For now I can only think of some hacks like creating a surrogate project for each jar or setting a mainClass in SBT each time before calling one-jar multiple times per build . These approaches obviously have their deficiencies . .. . Answer : It s not about SBT or onejar plugin . When you pack your project into the jar file both main classes would be packed . JAR File specification http : docs.oracle.com javase 6 docs technotes guides jar jar.html defines that you can have as many classes with main method as you want but there should be only one class with main method defined in Main-Class attribute per JAR Comment : Yep so what I m trying to achieve is for onejar to create one .jar file per each class with main that it finds in my src . It might happen that jars will be identical but Main-class attr will be set to a different value in each one . Onejar can clearly discover these candidates .

Answer : If you use the poorly-documented Maven Shade Plugin https : maven.apache.org plugins maven-shade-plugin usage.html instead of One-jar they can achieve similar results as each other it should solve your problems . It unpacks the dependent jars and stores the class files directly in the fat Jar rather than having jars within the jar . I have used it to create an executable-jar for running under JSVC with some success . Of course things are seldom as simple as they sound . With the Shade plugin you may have to do some work to relocate classes http : maven.apache.org plugins maven-shade-plugin examples class-relocation.html when there are conflicts in your dependency tree or use resource transformers https : maven.apache.org plugins maven-shade-plugin usage.html to handle your non-Java resource files .

Answer : I need to produce a jar file that will be used by others as a library lets call it myLib.jar thus the jar does not need to be executable .

While searching i found OneJar http : one-jar.sourceforge.net index.php page getting-started file quickstart and followed the 2 steps at the top of the page .

Q2 : If OneJar is intended only for executables is their another way to produce the myLib.jar library .. . .. . PS : If there is a need to add more information please let me know in order to edit my quetsion . Comment : Why not just package your own classes in myLib.jar and then inform users of your dependencies . Better yet if you used a build tool like Maven or Gradle you could declare your dependencies so that when they include your library they get them automagically Comment : Ideally i wanted to distribute just one jar without any dependencies and without expecting from the users to do anything else besides including this jar to buildpath . If this is not possible i may try something like maven . Comment : Also why do you think that this is a requirement It is totally reasonable to expect users of your library to have to have your dependencies on their classpath at runtime . I have never been discouraged from using a library simply because it had dependencies . Comment : Have you checked the license terms for your dependencies to make sure that it is OK to repackage the JARs . For at least some open-source licenses repackaging goes against the spirit if not the letter of the license . I m thinking of LGPL s rules about linking .. . which are intended to make it easier for your users to use a different version of the dependencies . Comment : You are going to create headaches when some wants to use myLib.jar with other libraries . Suppose myLib.jar had dependancy A version 1 . Some other library may have dependency A version 2 .

Answer : OneJar packages all of your code into a JAR file that also contains other JAR files in the lib directory or as a reference to them in other dirs outside the JAR depending on the onejar system you are using . It uses a custom class loader to make this work . Therefore it defeats your use of the system class loader . One way to defeat this is to use a class from the same JAR as the resource you want to load and therefore its class loader is probably setup correctly into the JAR or nested JAR or magic location in Narnia of your resource : .. . .. . Where MyClass is a class from the same JAR as merchant.id and the path to the resource must be absolute with the leading .. . .. . Be sure to get the stream and not the resource URL which might not be usable to you since it isn t an understandable URL to the system . It could produce a URL for a JAR within a JAR which the rest of Java wouldn t understand for example file : path to jarfile bot.jar config file.txt or worse . It could work but I m not sure when it is a JAR within a JAR with a file in it . A secondary option : .. . .. . Check your resource names : .. . .. .

Enumeration findResources String resource : returns an enumeration of resource URL s which match the given string .. . URL.openConnection : opens a connection to a resource by its URL . .. . One-Jar supports all of these mechanisms within the context of a One-Jar file which may contain Jar files that have duplicate resources .

I hope this is clear enough . Best Regards .. . Answer : The first problem with NoClassDefFoundError was setting correct classpaths I solved this by adding the maven-dependencies-plugin and included the class prefix attribute in the maven-jar-plugin . For one-jar plugin When building the one-jar file DOMConfigurator.configure method of log4j was not able to parse the log4j.xml file anymore as can be seen in the question above . I was able to replace this by log4j.properties file and using the PropertyConfigurator.configure method . Then the problem would be solved . However OneJar is causing another problem for me . Since it builds the first executable-jar into another jar I will need to change my code to find the path of the parent executable-jar to write log and properties files . For this reason I changed into the maven-assembly-plugin using its non deprecated single goal . In this case I can also keep the nice log4j.xml file . Below is the new pom.xml file : .. . .. . Moreover I uploaded the testing project into github : .. . .. . I Hope someone will find this useful . Comment : This helped me out greatly . Thanks . On minor note : You should mention that the maven-assembly-plugin is building a somewhat shaded jar https : maven.apache.org plugins maven-shade-plugin and that the classpathPrefix lib classpathPrefix property is unnecessary because the jar will have all the dependencies embedded within it . You only need this if you are using a non-shaded light-weight jar because the jar will reference the lib directory which exists beside the light-weight jar sans dependencies .", "Question : I have a project that only builds the fat onejar file for testing purposes . Thus there s a separate testing class that I don t want as a dependency to the main source but I do want it included into the onejar . Odd scenario I know . I m using the com.smokejumperit.gradle.OneJarPlugin plugin source here https : github.com RobertFischer gradle-plugins blob master src main groovy OneJarPlugin.groovy and clearly it gets the list of files to include in the onejar here : .. . .. . jar.output.files is used for publishing so I don t want a this second jar file being published and the two project.configurations would define dependencies for the main source jar and I don t want this second jar to be a dependency of that either .

Ideas Comment : Just put a dummy class in the main source that depends on the jar in question . Ugly but effective . Comment : Not sure what you mean exactly . Can you give an example The integration jar file is separate because it has some dependencies I don t want the main source to have like jetty . Do you mean a class that simply loads the jar file into the classpath or something Not sure what that might look like . .. . Answer : I m not familiar with the implementation of that plugin but I d be surprised if inputs.files determined what gets included . Usually inputs is just consumed by Gradle s up-to-date check .

Answer : what am I trying to do : .. . .. . first let me present a very simplified version of what i m trying to achieve . consider the following multi-project : .. . .. . the backend is packaged with oneJar https : github.com sbt sbt-onejar and performs as a standalone process that does the background work . the frontend is a web-service play http : www.playframework.com project packaged as a zip file with dist . the deployer is yet another self executable-jar that is packaged with oneJar https : github.com sbt sbt-onejar but the packaging is modified to include the other projects artifacts . the deployer job is to initialize the system . it deploys the other artifacts to specified machines and initializes the distributed-system . what is my problem : .. . .. . basically i m trying unsuccessfully to get the play s dist zip artifact the backend oneJar self executable artifact packaged inside the deployer jar with other resources files .. . .. . the deployer jar should look like : .. . .. . what do I have so far : .. . .. . build.sbt .. . .. . backend build.sbt .. . .. . frontend build.sbt .. . .. . deployer build.sbt .. . .. . notice that in the root build.sbt i have per-configuration classpath dependencies http : www.scala-sbt.org release docs Getting-Started Multi-Project.html per-configuration-classpath-dependencies optional- compile .

In my maven project setup I have a file in base src main resources template.html .

Answer : I managed to find the answer after a lot of digging . The code to use the ClasspathResourceLoader is as follows : .. . .. . Secondly many people are telling me that inside of a nested jar the standard classpath loader shouldn t even be able to find the template.html file . I was told that some fancy third party classloader would be necessary . OneJar provides such a fancy loader . Once I got the code correct to use the ClasspathResourceLoader things seemed to resolve . The thing to keep in mind is that is relative to the classpath root . So when base src main resources template.html got repackaged as template.html in the root directory of the unpacked JAR that meant that template.html was the right resource path to load . That path template.html is of course relative to the nested inner JAR .

It ended up being trickier than I thought because I went in not fully understanding how the boundary part works eventually I worked out that the starting and ending -- were significant and off it went . Very barebones really and obviously the using inline CSS to hide the form is a bit cheap and you d almost certainly want a bit more feedback to the user Also I d probably spend a bit more time working out what the actual Content-Type for the file is rather than cheating and using application octet-stream but that part is quite as interesting . Comment : This is the best response so far in my opinion as you are the only one to provide full code which the question specifically asks for . +1 . Comment : It s fine to use md5 for the boundary for golf but for production you should double check that the boundary doesn t occur in the encoded attachment .

I m not familiar with Perl and my inclination is to just use the PHP mail function and drop the Perl script rather than spend time trying to figure out how to use it correctly . So is there any good reason to keep using the Perl script or should I just advise him to drop it in favor of PHP mail Any pros and cons or is it entirely subjective I realize that this question may be flagged as subjective just looking for advice . .. . Answer : I d recommend a third option : an external PHP mailer class such as PHPMailer . This gives you the advantage of not mixing languages unnecessarily as well as not having to figure out the quirks of mail . It also does things like SMTP email itself if required and can assemble attachments and alternate sections . mail can do none of that . PHP s mail function needs to be caught and shot . It s one of the quirkiest and odd functions that PHP has and requires some knowledge of how SMTP and often MIME work to call .

We have two Windows Server 2008-R2 servers that are being used to test drive Web Deploy : QA and Staging .

For some reason our Staging server generates backup ZIP files that only contain two files : .. . .. . archive.xml .. . systemInfo.xml .. . .. . The Contents directory is not there and there is no error being logged in Windows Event Logs . What s worse is that the servers are configured to not continue up on backup failure continueSyncOnBackupFailure false but this obvious failure to add the Contents directory is seemingly not regarded as an error by the tool so the tool happily continues to deploy the package .

Keep in mind that if you are using an IIS user you ll need to make sure you ve configured delegation rules such that the contentPath provider will be able to write to the website s directory with the correct permissions .

I know this isn t the answer you were looking for nor was I but the sad fact of the matter nevertheless .

Only downside to this method is that it will create a backup every time you compile not just when you deploy . Otherwise you ll have to write a special script that you run prior to each publish . On a side note you can also edit your web deploy configuration via IIS Manager at the server level using the Configuration Editor must have the Management role installed . enter image description here http : i.stack.imgur.com Fhhfw.png Comment : Thanks .

Answer : Microsoft is being super sneaky about this but it appears they have removed the ability to use web deploy remotely from ALL non server os s . Even in Windows 7 if you do all of the newest updates the deploy menu vanishes in IIS . So if you want to use web deploy it seems like your only option is to shell out some bucks for a server os .

Before asp.net dev team provide a better solution you can just follow the instruction from docs.asp.net Publishing to IIS with Web Deploy using Visual Studio 2015 https : docs.asp.net en latest publishing iis-with-msdeploy.html .. . .. . To publish an ASP.NET 5 application to a remote IIS server the following steps are required . 1 . Configure your remote IIS server to support ASP.NET 5 .. . 2 . Create a publish profile .. . 3 . Customize the profile to support Web Deploy publish", "Question : null .. . Answer : I m trying to migrate a site to a new server using Microsoft Web Deploy . The command I m using is the following : .. . .. . When I run it locally on the server itself it copies all of the site information that I want but it sets the Connect As user in the site s Basic Settings as SANDBOX sandbox usr . But as I m working on automation I m not running the script locally I m executing it from a uDeploy server . When I execute it from my uDeploy server everything gets put onto the server but the user that s set is sandbox usr which isn t what I want . I tried using the Authtype flag in web deploy but that didn t do it for me . Any ideas Comment : have you tried starting it with start-process and pass it credentials this way Since i dont see where you declare the user i assume it uses the user that runs the command Comment : @Paul the user account that s running the scripts in both local and remote script execution are SANDBOX pcort . What I did to get the IIS package was create a template of the IIS set up we wanted and then we re going to deploy that to servers . What I m not understanding is why the domain is there when I run it locally but not when I run it remotely .", "Question : The title needs some expansion . In summary I am finding it impossible to : .. . .. . Deploy a web site to an IIS 8 host .. . Using a Web Deploy Package .. . Using the out-of-the-box publish functionality in VS 2013 .. . Using a non-admin IIS Manager User which is delegated permission to deploy to the given site .. . .. . It all seems to come down to one small detail that messes it all up but I should describe my process up to the point where it all falls apart . I create a publish profile Publish in VS 2013 configured to publish to a web package . I then fire the following command at a developer command-prompt : .. . .. . This goes through a build-process and I now see the expected package and deployment files in the PublishedWebsites Web Package folder . My next step is run this from the Web Package folder : .. . .. . This is where the problem comes in . This results in the following expanded command formatted for ease of reading : .. . .. . whose execution results in : .. . .. . I can fix this problem by manually re-running just the expanded command and tagging on the site parameter to the MsDeploy.axd URL like so : .. . .. . However I cannot see any way to have this set through Web.deploy.cmd which was auto-generated by MSBuild . If I try this : .. . .. . It results in this again formatted for ease of reading : .. . .. . I can perform this process fine using an admin account . But it seems that the non-admin requires this site querystring value and the auto-generated Web.deploy.cmd just isn t having any of that . Am I missing something obvious here Is there a permission I m missing on the IIS Management side I ve made sure I have the Management Service Delegation rule set up as directed in this blog post http : blogs.msdn.com b amol archive 2011 02 09 allowing-non-admin-users-to-deploy-web-applications-on-iis-7-using-web-deploy-2-0.aspx . .. . Answer : I can t see a way around this using the process I ve laid out . My solution here is to simply take the expanded MSDeploy.exe command-line and use it directly instead of the generated .deploy.cmd file . Of course if anyone comes along with an actual solution to my original problem I ll happily mark that one as the answer . Until then this is my solution .", "Question : I would like to try the Web Deploy method to deploy our website . Before my questions I would like to provide a few details about the current deployment procedure : .. . .. . 1 . It is an enterprise site is hosted on multiple servers with continuous-deployment . 2 . The files are not in Release mode but in Debug mode . 3 . We manually copy-paste only the current assignment related files . Say this week the Accounts module is to be deployed then the files to be deployed are .. . mysite App Code Models accounts.cs .. . mysite pages accounts.aspx accounts.aspx.cs .. . .. . The 3 files will be copied to the respective folders in all the servers manually . This has been the procedure for years here . 4 . The project mysite is an ASP.NET Website and not ASP.NET Web Application in VS2013 which means these options are unavailable - Package Publish Web Package Publish SQL .. . .. . I have created the packages in the dev system .. . i using the publish option web-deployment package in Visual Studio and also .. . ii export application in IIS gives the option to select the files .. . .. . 1 . Is it possible to create a package only for the files I need in this case accounts.cs accounts.aspx accounts.aspx.cs using VS publish feature . 2 . Is it possible to include custom SQL scripts file in the package . using IIS or VS .. . 3 . If the answer is a Yes for Q2 then it should be executed only once not for all servers . Because there is only one DB server . How can it be done . I did not go for the Installing package part yet . .. . Answer : 1 - Not through VS because there is no extension point that I know of into MSBuild for Websites . Sayed has a great post http : sedodream.com 2012 08 06 PlansRegardingWebsiteProjectsAndWebDeploymentProjects.aspx which describes how Websites are treated differently than Apps . Alternative - You could copy the files you wish to deploy to a new folder and then use the MSDeploy.exe commandline tool to create a customer MSDeploy package which you can deploy to your server . 2 3 - Yes you could include SQL into the web-deployment package but it would be deploy each time the package is deployed . We have found its better to seperate our SQL deployments into its own package so we can deploy it only when we want to . This post describes how we handle our SQL deployments - https : dotnetcatch.com 2016 02 10 deploying-a-database-project-with-msdeploy", "Question : I followed this http : martinbuberl.com blog deploy-aspnet-mvc-on-amazon-ec2-with-web-deploy tutorial .. . .. .

The following is a UNION query that uses an ORDER BY clause : .. . .. . .. . select supplier id supplier name .. . from suppliers .. . where supplier id 2000 .. . UNION .. . select company id company name .. . from companies .. . where company id 1000 .. . ORDER BY 2 .. . .. . .. .

Or use a place holder array that is your original order and fetch the results from database in whatever order loop the place holder array and set it accordingly . You already has the chicken why you still wondering how the egg laying .. . Answer : There is no auto-sorting or default sorting going on . The sorting you re seeing is most likely the natural sorting of rows within the table ie . the order they were inserted . If you want the results sorted in some other way specify it using an ORDER BY clause . There is no way in SQL to specify that a sort order should follow the ordering of items in an IN clause . Comment : More accurately there is no way to specify ordering in the WHERE clause . Comment : @JonhFx : +1 Thanks for broadening the scope of my statement . Comment : read the question try it on your query. . it sorts when you specify the in keyword. . anyways. . i just added ORDER BY FIELD id values in the end and it worked. . Comment : @Nauman Bashir : I did re-read the question and stand by my answer . There is no sorting going on without an ORDER BY . You re getting the results back in the order that they happen to be present in the table which in your case happens to be in ascending order of the id column . But this simply isn t true in the general case . In any case your solution that uses ORDER BY FIELD is a good one .

Answer : Follow the step. . .. . .. . 1 . First give alias for the columns inside select statements..since its union the alias should match in all queries . 2 . put an outer select with the alias names and do orderby using the alias of the column u needed .

I came up with the following : .. . .. . which gives the result : .. . .. . I however require that the order of winners for each subject be further sorted by name i.e . the result above should become Caesar Milstein as 3rd followed by Georges J.K . Kahler and then Niels K .

Comment : just add the second order criteria to your ORDER BY : ORDER BY CASE WHEN ......END subject winner Comment : As most people here have pointed out adding winner to the ORDER BY clause should resolve this . However I am running the query on the mentioned website itself and I m guessing perhaps wrongly it is the use of MariaDB that results in a different output . In any case the addition of winner to the ORDER BY is causing the results to be sorted only by winner ignoring the subject column . The page I found this question on is this - sqlzoo.net wiki SELECT from Nobel Tutorial - Question no . 14 in case anyone is curious about the source .

Removing the brackets the result is the same as before Comment : do some this like select orderline.orderlineno ....from select...union select...union orderby 1 asc give alias to each column in the inside select and use it in outer select..this way i achieve sort in my pgms..dont know whether it will solve ur issue .. . Answer : Your SQL was fine . Might as well leave off the order by on the union . Set the sort order in the datawindow itself . Drag the column want to sort by over to the right hand side and uncheck the Ascending box .

Answer : Just add the winner to your order by statement : -", "Question : I was wondering how sql-server sorts it s data . I noticed that if I have a table that doesn t contain the column Id and you select data without ORDER BY sql-server doesn t automatically sort on the primary column . Does anyone know what rule sql-server follows to sort it s data Comment : +1 good question .. . Answer : Although it s good to wonder about how it might be explained that you often see the same order I d like to point out that it never a good idea to rely on implicit order caused by the particular implementation of the underlying database engine . In other words its nice to know why but you should never ever rely on it . For MS SQL the only thing that reliably delivers the rows in a certain order is an explicit ORDER BY clause . Not only do different RDMBS-es behave differently one particular instance may behave differently due to an update patch . Not only that even the state of the RDBMS software may have an impact : a warm database behaves differently than a cold one a small table behaves differently than a large one . Even if you have background information about the implementation ex : there is a clustered-index thus it is likely the data will be returned by order of the clustered-index there is always a possibility that there is another mechanism you don t know about that causes the rows to be returned in a different order ex1 : if another session just did a full table scan with an explicit ORDER BY the resultset may have been cached a subsequent full scan will attempt to return the rows from the cache ex2 : a GROUP BY may be implemented by sorting the data thus impacting the order the rows are returned ex3 : If the selected columns are all in a secondary index that is already cached in memory the engine may scan the secondary index instead of the table most likely returning the rows by order of the secondary index . Here s a very simple test that illustrates some of my points . First startup SQL server I m using 2008 . Create this table : .. . .. . Examine the table and witness that a clusted index was created to support the primary-key on the id column . For example in sql-server management studio you can use the tree view and navigate to the indexes folder beneath your table . There you should see one index with a name like : PK test ord 3213E83F03317E3D Clustered .. . .. . Insert the first row with this statement : .. . .. . Insert more rows by repeating this statement 16 times : .. . .. . You should now have 65536 rows : .. . .. . Now select all rows without using an order by : .. . .. . Most likely the results will be returned by order of the primary-key although there is no guarantee . Here s the result I got which is indeed by order of primary-key : .. . .. . the is not a column but the ordinal position of the row in the result .. . .. . Now create a secondary index on the name column : .. . .. . Select all rows but retrieve only the name column : .. . .. . Most likely the results will be returned by order of the secondary index idx name since the query can be resolved by only scanning the index i.o.w . idx name is a covering index . Here s the result I got which is indeed by order of name . Now select all columns and all rows again : .. . .. . Here s the result I got : .. . .. . as you can see quite different from the first time we ran this query . It looks like the rows are ordered by the secondary index but I don t have an explanation why that should be so . Anyway the bottom line is - don t rely on implicit order . You can think of explanations why a particular order can be observed but even then you can t always predict it like in the latter case without having intimate knowledge of implementation and runtime state .", "Question : I am working on a plsql procedure where i am using an insert-select statement .

You need to use an order by when you select from the table you inserted into Comment : @a horse with no name is exactly right .

South Sudan put into it that were not alphabetical with the rest of the records above them . This makes for more not much more but still more coding when binding the table to a dropdown on a page with .DataBind where you are not controlling the SQL you get so it makes sense to start with the table instead .

Comment : @ShannonSeverance .. . and also for reducing clustering factor on particular indexed column s as well . .. . Answer : The typical use-case for an ordered insert is in order to co-locate particular value in the same blocks effectively reducing the clustering factor on indexes on columns by which you have ordered the data . This generally requires a direct path insert .. . There s nothing invalid about this as long as you accept that it s only worthwhile for bulk data that the data will load above the high water mark only and that there are locking issues involved . Another approach which achieves mostly the same effect but which is more arguably more suitable for OLTP systems is to create the table in a cluster . Comment : but that is not lourdh s intention . The OP expects the rows returned in the order they were inserted when selecting them - which is a wrong assumption . And not even the append hint with an order by will guarantee that . Comment : @a horse with no name indeed but I m just focusing on the idea that an insert with order by is of no value . Comment : @a horse with no name ACTUALLY it worked for me to both insert in the right order and show it when doing a SELECT on the table afterwards so why can t it be guaranteed when dealing with static data i.e . ID NAME in a table of Countries that inserting this data into another New Countries Table using the + append hint won t always work Would like to know so I know when to use this hint and when not to.. . Comment : @vapcguy : Because rows in a relational-database are NOT sorted . Without an order by the DBMS is free to return the rows in any order it likes . The append hint has nothing to do with sorting rows . Comment : @a horse with no name True but that s why you append an ORDER BY clause on your INSERT statement like in this answer above .

SELECT article FROM table1 ORDER BY publish date LIMIT 20 .. . .. . How does ORDER BY work Will it order all records then get the first 20 or will it get 20 records and order them by the publish date field If it s the last one you re not guaranteed to really get the most recent 20 articles . Comment : Note that if some publish date s are equal ordering by them does not give determinate results meaning that if you use LIMIT for pagination you may end up getting the same items on different pages .. . Answer : The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement . LIMIT takes one or two numeric arguments which must both be nonnegative integer constants except when using prepared statements . With two arguments the first argument specifies the offset of the first row to return and the second specifies the maximum number of rows to return . The offset of the initial row is 0 not 1 : .. . .. . SELECT FROM tbl LIMIT 5 10 Retrieve rows 6-15 .. . .. . To retrieve all rows from a certain offset up to the end of the result set you can use some large number for the second parameter . This statement retrieves all rows from the 96th row to the last : .. . .. . SELECT FROM tbl LIMIT 95 18446744073709551615 .. . .. . With one argument the value specifies the number of rows to return from the beginning of the result set : .. . .. . SELECT FROM tbl LIMIT 5 Retrieve first 5 rows .. . .. .

The example is right from the MySQL Documentation http : dev.mysql.com doc refman 5.0 en select.html Comment : Number 5 is the 6th row . 5 rows 0 through 4 are ignored . Comment : But using LIMIT without ORDER BY may give inconsistent results Unfortunately the entire result set must be ordered before the LIMIT is applied or the the DBMS is free to arbitrarily order the result and then OFFSET and LIMIT on that set .

The order of the result was always descending as I needed . Last week I just migrated to a new MySQL Version In fact I migrated to MariaDB 10.0.14 and now the same query with the same database is not sorted descending anymore . It is sorted ascending or sorted using the natural order not sure in fact .

Plante Comment : Possibly relevant : mariadb.com kb en mariadb https : mariadb.com kb en mariadb group-by-trick-has-been-optimized-away .. . Answer : After a bit of digging I can confirm both your scenarios : .. . .. . MySQL 5.1 does apply the ORDER BY inside the subquery . MariaDB 5.5.39 on Linux does not apply the ORDER BY inside the subquery when no LIMIT is supplied . It does however correctly apply the order when a corresponding LIMIT is given : .. . .. . Without that LIMIT there isn t a good reason to apply the sort inside the subquery . It can be equivalently applied to the outer query . Documented behavior : .. . .. . As it turns out MariaDB has documented this behavior https : mariadb.com kb en mariadb faq general-faq why-is-order-by-in-a-from-subquery-ignored and it is not regarded as a bug : .. . .. . A table and subquery in the FROM clause too is - according to the SQL standard - an unordered-set of rows . Rows in a table or in a subquery in the FROM clause do not come in any specific order . That s why the optimizer can ignore the ORDER BY clause that you have specified . In fact SQL standard does not even allow the ORDER BY clause to appear in this subquery we allow it because ORDER BY .. . LIMIT .. . changes the result the set of rows not only their order . .. . You need to treat the subquery in the FROM clause as a set of rows in some unspecified and undefined order and put the ORDER BY on the top-level SELECT . So MariaDB also recommends applying the ORDER BY in the outermost query or a LIMIT if necessary . Note : I don t currently have access to a proper MySQL 5.5 or 5.6 to confirm if the behavior is the same there and SQLFiddle.com is malfunctioning . Comments on the original bug report https : mariadb.atlassian.net browse MDEV-3926 closed as not-a-bug suggest that MySQL 5.6 probably behaves the same way as MariaDB . Comment : Thank you very much . I applied the order by to the outermost query and it work well now . Comment : @Michael It is typical for order by not to apply inside a subquery isn t it I don t think any db would guarantee that ordering . Comment : @Pacerier As noted in the quoted docs SQL standard does not even allow the ORDER BY clause to appear in this subquery so most RDBMS probably won t allow it .

Can anyone see what I m doing wrong Do I need to make a nested query Comment : Invalid ORDER BY . When GROUP BY and SELECT DISTINCT and UNION etc only select list items may be specified in the ORDER BY . .. . Answer : The reason this doesn t give you the results you want is how GROUP CONCAT works . With standard SQL any field in the SELECT must either be also mentioned in the GROUP BY clause or must be an aggregate field there is an exception for fields 100 related to a field that is returned but many flavours of SQL do not support this . MySQL does allow a field to be in the SELECT clause which is not an aggregate value and is not mentioned in the GROUP BY clause and allowing this was the default until recently . However for these fields there could be multiple values for the GROUP BY fields and in this case which one is chosen is not defined . As this is worked out prior to the ORDER BY statement being processed the ORDER BY clause has no effect on which one is chosen . There are a few normal ways to do this . You can use a as Gordon has suggested or similarly and possibly more efficiently depending on records and indexes you can use a sub query to get the latest rows date for each of your important rows and then join that back to your main table : - .. . .. . In some situations another option is to ab use the GROUP CONCAT and SUBSTRING INDEX functions . This way you can GROUP BY the fields you want to but do a GROUP CONCAT or the other fields in the descending order of the date . Then use SUBSTRING INDEX to get everything up to the first comma the default delimiter for GROUP CONCAT : - .. . .. . Obviously this has issues if the latest row has a null value hence I have used COALESCE to fudge in non null values . Also if the field contains commas you will need to use an alternative delimiter . And if the field is large then you might have issues with the max field length for GROUP CONCAT default is 1024 I think . Comment : Thanks for the explanation", "Question : This only happens for queries that force GROUP BY after ORDER BY . Goal : .. . .. . Get latest balance for each unit for the given cardID . Table : .. . .. . Query : .. . .. . Expected Result MySQL v5.5.38 : .. . .. . Unexpected Result MySQL v5.7.13 : .. . .. . After upgrading to MySQL v5.7.13 the result returns the initial balances as-if no deduction occurred for the given card . Is this a bug in MySQL version Would you suggest any other more reliable way to solve this Comment : See MySQL Handling of GROUP BY https : dev.mysql.com doc en group-by-handling.html . .. . Answer : This is a bug in your use of the database . MySQL is quite explicit that when you include columns in the SELECT clause in an aggregation query -- and they are not in the GROUP BY -- then they come from indeterminate rows . Such syntax is specific to MySQL . It is not only a bad idea to learn but it simply normally not work in other databases . You can do what you want in various ways . Here is one : .. . .. . This has the advantage that it can use an index on cardBalances unit CardId date . Comment : Thanks your query is meaningful and works as expected . But I didn t quite understand why this same query returns different results . I get that they become indeterminate rows but it s the fact that versions handle this in a different way . Comment : Grouping with just using takes the top row . However sql is working on sets unordered of tuples unless specifically ordered . your subquery might be explicitly ordered your query however sees a temporary result which is a table and it should group it .. . if the table is sorted or not is at that point irrelevant . So the result is indeterminate and it wouldn t even work in other database systems because is not an aggregate column in your query . mysql is .. . sloppy . and now you have to do real sql Comment : different versions with different results : could be optimization btw . ordering is usually expensive so if there is no necessity to do it .. . don t do it o", "Question : When querying the db for a set of ids mysql doesnot provide the results in the order by which the ids were specified . The query i am using is the following : .. . .. . in return the result provided is in the order 1 3 5 7 9 . How can i avoid this auto sorting Comment : I once receive this request from one of my company developer I simply reply Seems you have the precise information of 7 1 5 9 3 why you still need to sort it again Comment : @ajreal i get these ids from another server . n i need to query the db in the relevant order . i dont wanna sort it the db returns in a sorted way. . i wanna avoid the sorting : Comment : . . ARGGGGG...you already have these IDs in the ORDER of 7 1 5 9 3 why you need to sort it again Two solution query one id by id . Or use a place holder array that is your original order and fetch the results from database in whatever order loop the place holder array and set it accordingly . You already has the chicken why you still wondering how the egg laying .. . Answer : The WHERE clause in SQL does not affect the sort order the ORDER BY clause does that . If you don t specify a sort order using ORDER BY SQL will pick its own order which will typically be the order of the primary-key but could be anything . If you want the records in a particular order you need to specify an ORDER BY clause that tells SQL the order you want . If the order you want is based solely on that odd sequence of IDs then you d need to specify that in the ORDER BY clause . It will be tricky to specify exactly that . It is possible but will need some awkward SQL code and will slow down the query significantly due to it no longer using a key to find the records . If your desired ID sequence is because of some other factor that is more predictable say for example you actually want the records in alphabetical name order you can just do ORDER BY name or whatever the field is . If you really want to sort by the ID in an arbitrary sequence you may need to generate a temporary field which you can use to sort by : Comment : well. . thanks for the info. . but i am generating the query on run time. . so this would be a bit lengthy. . i just added ORDER BY FIELD id values at the end of the query. . im just worried about the performance issues" ] }

You would need to subclass it and override removeEldestEntry http : docs.oracle.com javase 7 docs api java util LinkedHashMap.html removeEldestEntry java.util.Map.Entry with logic to signal when the cache has grown larger than you want it . If multi-threaded usage is necessary then you ll need to wrap operations with appropriate synchronization . Caffeine was heavily inspired by the Guava Cache https : code.google.com p guava-libraries wiki CachesExplained which similarly provides concurrent access and has approximate LRU behavior . A quick test of your code against the Guava cache shows similar results . I am not aware of any standard-library that would provide predictable externally observable LRU results and true concurrent access without a coarse-grained lock . You might reconsider whether it s really a requirement to have strict externally observable LRU results . By its nature a cache is fast temporary storage to provide optimized lookups . I would not expect program behavior to change drastically dependent on whether the cache implements strict LRU an approximation of LRU LFU or some other eviction policy .

Comment : @AndyTurner I think the confusion is my prior involvement with Guava and Caffeine s similarities . Kevin has said he favors transitioning Google over to Caffeine after the JDK8 release but I think how the relationship will evolve is still an unknown . .. . Answer : The term eden was borrowed from JVM generational garbage collectors where most objects die young and are not promoted . We later decided on window when coming up with a name for the eviction policy Window TinyLFU . In the simulator https : github.com ben-manes caffeine wiki Simulator you can adjust the window size by modifying the percent-main in the configuration file https : github.com ben-manes caffeine blob master simulator src main resources reference.conf L171 . That makes it easy to experiment with different trace files when evaluating policies and the impact of tuning options . For the production facing cache the window size is not a configuration parameter . This value is hard coded to 1 which was near optimal across a variety of workloads and avoids TinyLFU s degredation scenarios . In some workloads OLTP disk traces a larger value has a small gain but not enough to expose a configuration option .

Comment : @BenManes yeap there is a bound to jcache api . also we re using spring 4.2.4 and waiting for a 4.4 to come in so there will caffeine support in it . anyway thank you for a hint :", "Question : I want to use Caffeine for caching and I need to have a write-behind . I want to limit the amount of times I write to the database . The documentation https : github.com ben-manes caffeine wiki Writer speaks of write-back cache so it should be possible but there is no example there on how to configure it . I have implemented a CacheWriter but I don t understand how to configure it to for example only call the writer once every 10 seconds If something changed to the cache ofcourse . .. . Answer : CacheWriter is an extension point and the documentation describes the use-cases where it may make sense . Those cases are beyond the scope of the library and if implemented instead could have been too rigid . The writer is called atomically during a normal write operation but not a computation . This ensures that a sequential order of changes is observed for a given key . For write-behind the writer would add the entry into a queue that is processed asynchronously e.g . to batch the operations . When implementing this capability you might want to consider .. . .. . Coalescing the updates e.g . collect into a LinkedHashMap .. . Performing a batch prior to a periodic write-behind if it exceeds a threshold size .. . Loading from the write-behind buffer if the operations have not yet been flushed This avoids an inconsistent view e.g . due to eviction .. . Handling retrials rate-limiting and striping depending on the the characteristics of the external resource Comment : Ah that was totally not clear . Maybe the first section that has no title can get a title Usage and the other 3 titles can be grouped under a new title Possible use cases . Maybe even with a note that these are things that are possible to implement on top of that CacheWriter but are not available in Caffeine . In the end I went with Hazelcast as they have write-behind out of the box . Comment : Thanks I ll improve the documentation then . I think a community extension to offer this capability would be nice . I d like Caffeine too feel like a library flexible small obvious focused to avoid the mistakes many framework authors make . Hopefully it is extensible enough to be used as a building block to handle aspects outside of its scope .", "Question : I have configured my cache as follows : .. . .. . Also I have the @Service that uses it in following way : .. . .. . So I have the next behavior . 1 . When I m calling the service method first time it takes 5 seconds then doing some work as expected . 2 . Calling method the second time with same parameters - caching works - returns result immediately .. . 3 . Calling the third time with same parameters again results in Thread.sleep .. . .. . And all over again . How to solve this Is that the issue about proxying What did I miss Comment : Perhaps there is a bug in the cache s expiration logic The TCK doesn t provide much coverage here unfortunately so more tests are desirable for the JCache adapter . Can you wrap this into a sample so that I can debug it with you Also note that version 2.0.3 https : github.com ben-manes caffeine releases fixed some JCache issues . Comment : I think you found a bug . When the access time is updated after a get https : github.com ben-manes caffeine blob master jcache src main java com github benmanes caffeine jcache CacheProxy.java L173 the new time set to the current millis and not adjusted https : github.com ben-manes caffeine blob master jcache src main java com github benmanes caffeine jcache CacheProxy.java L1065 by the expiry duration . I ll fix this and add some additional tests over the weekend . Sorry about that . Comment : @BenManes currently we are using version 2.0.3 of caffeine lib Comment : @BenManes that s cleared something waiting for a bugfix . thank you for replying Comment : I pushed a fix available as a snapshot . I ll spend time over the weekend to add JCache tests and try to have a release out Sunday night . .. . Answer : As discussed in the comments this was a bug in the JCache adapter . Thank you for letting me know about this problem . I released version 2.1.0 https : github.com ben-manes caffeine releases tag v2.1.0 which includes this fix . That release also includes friendlier initial settings for CaffeineConfiguration which you identified in another post http : stackoverflow.com q 34809817 19450 . While the core library is heavily tested the JCache adapters relied too heavily on the JSR s TCK test compatibility kit . Unfortunately that test suite isn t very effective so I added tests to help avoid these types of mistakes in the future . This issue only occurred in JCache because its version of expiration is not supported by Caffeine s core library . Caffeine prefers to use an O 1 design that eagerly cleans up expired entries by using fixed durations . JCache uses per-entry lazy expiration and the specification authors assume a capacity constraint is used to eventually discard expired entries . I added a warning https : github.com ben-manes caffeine wiki JCache to the documentation about this feature as it could be error prone . While none of the other JCache implementations go beyond this a pending task is to decide on a mechanism to help mitigate this JCache design flaw . Thanks again for reporting this issue . As always feel free to reach out if you have any other issues or feedback to share . Comment : thank you for fast bugfixing and detailed explanation for what happened great to see that", "Question : null .. . Answer : I am trying to build a cache using https : github.com ben-manes caffeine where I need to fetch all entries during boot up time and I do not know all the keys before hand . My CachLoader has something like this and trying to cache all at startup . But looks like I will need to know all the keys before hand if I want to prefetch all entries in to cache Am I missing anything So say I call cache.getAll 10 and only 10-- 100 will be cached even though the loadAll method returns 3 entries 10-- 100 20-- 400 30-- 900 Comment : What is your specific question Comment : my question is do I need to know all possible keys before hand so that i can prefetch all possible entries Comment : loadAll is allowed https : github.com ben-manes caffeine wiki Population loading to return a larger mapping than the keys requested and all will be cached but only the requested entries returned . If you want to load everything then you might not have a key-value cache and Guava s Suppliers.memoizeWithExpiration could be a better fit . Comment : Thanks a lot for the reply Ben . looks like i do not need to know all possible keys . I can pass in a fake key and load them all in loadAll" ] }

I will be starting with either a RGBYTP red green blue yellow teal or purple color then through hue adjustments I will be able to make it look like each one of the other RGBYTP colored images .

A common technique in web game design . eyeballs http : quadradius.com stuff RandomImagesForLinking hue-adjusted-eyeballs.jpg .. . .. . I often use GreenSock Animation Platform TweenLite TweenMax but both core AS code and the TweenLite engine don t seem to handle hue as I expect . I want to adjust the hue color wheel by an increment of 60 degrees which should adjust through all 6 secondary colors nicely and get a full bodied color result from it . But what I actually get is horrendous . In fact adjusting the hue of an RGBYTP color returns very weird results earth tones pastels even shades of gray . bad-hues http : quadradius.com stuff RandomImagesForLinking 6-colors-all-hue-adjusted.jpg .. . .. . Here is the code I use to generate all those circles with . Why do AS3 or TweenLite Max not handle hues like Photoshop or an artists color wheel What am I doing wrong Comment : Flash only supports RGB and ARGB colour formats . You ll need to cycle thru hues and convert each one to RGB format before applying it - googling should provide some algorithms for converting Comment : I m already using what many consider to be a great package of algorithms the GreenSock platform . It is used for tweening transformations timers and color manipulation and includes a hue function . But even their arguably respected hue function seems to return lacking results . The results of the algorithm are in the image with the circles I included . For example if you start with purple you can never produce yellow . .. . Answer : Two colors don t go straight to black on the Real Color Wheel . Yellow goes to brown first and cyan goes to blue first . The brown is reds darkest color before black . Cyan goes to blues darkest color before black . I don t know any java but I sure would like a java wheel like this one . http : acko.net blog farbtastic-jquery-color-picker-plug-in .. . .. . The yellow eye is using the RGB gradation to dark and that s why it looks greenish the same for the cyan colored eye . I have the coded gradations in a table I made on this website . http : www.realcolorwheel.com colorwheel.htm You can get the color-codes on the source page . Don RCW Comment : Nice color wheel and it looks like you know your color rules But not sure if that answers it . The top image made in photoshop is just an example of what I want . When using the built-in Hue function in the Tweenlite package I don t get those results at all circles image . For example if I start with red the hue function produces a brown Purple will never get you anything close to yellow One of blue s go to near black It s like the hue algorithm is more suited to pick another pretty color rather than a hue adjusted output .

It works", "Question : I am using TweenLite to complete some SVG animations but for some reason every time i reload the page the first time I hover the element with the animation the durration of the animation is instant . Then after the first time the hover effect is added instantly the animation works properly . CodePen http : codepen.io Zlerp pen adEZzE .. . .. . Just reload the page hover the object and you will see the error I am receiving . Thanks for your time .. . Answer : The main problem is not in the javascript but in the CSS . The .social-circle class does not have a fill which means it is actually 000 . This solves the initial animation http : codepen.io foozle pen zrpBmL you may or may not have noticed that the fill -animation uses a somewhat bright-colored transition from nothing to the purple . This seems to be because TweenLite interprets fill : none as fill : rgba 255 255 255 0 the latter being transparent white which in itself is not visible but the steps in the transition are . This is why I opted for the transparent version of your color in the code above . Now that your question is answered I feel like I should take some time to help you reducing the overall complexity of your solution . The way I see it you have used two different and rather large javascript libraries to achieve what should have been a very simple CSS declaration .

Comment : @coner Remove the last line of the init function .", "Question : Using GSAP I want to create one TweenLite or TweenMax object which acts different animations intended to play in parallel on multiple different objects . How can this be done I have only seen allTo which applies same animation on an array of multiple objects . It is important to get one tween as I need to pass it to ScrollMagic . I figured I can use TimelineLite or TimelineMax to do this too since that s OK with ScrollMagic . However is it possible purely using TweenLite or TweenMax Or the timeline is the only way to go Comment : If you intend to do different animations on multiple elements then yes TimelineMax is the best option . And I believe ScrollMagic can take TimelineMax and treat it as one single tween based on the assumption that you are going to be using its setTween method . .. . Answer : If you were to just use TweenMax and not TimelineMax . . then you could just use method-chaining and chain your tweens using TweenMax .. . .. . Using TimelineMax would be give you greater control . You could also chain with the TimelineMax constructor : .. . .. . Or just do like you were doing but with chaining : .. . .. . See TweenMax docs for more information : http : greensock.com docs HTML5 GSAP TweenMax Comment : Although you can chain TweenMax or Lite the .to method in TweenMax is a static method https : greensock.com docs HTML5 GSAP TweenMax to . Hence the tweens variable will just have the last call s tween object the other animations will play but won t be controllable . There is no true chaining happening and the code is misleading . In TimelineMax or Lite the .to method is non-static https : greensock.com docs HTML5 GSAP TimelineMax to so you are in fact doing a true chaining . Comment : Also I don t see the point in your last code block . If I already assigned it to var timeline why re-assign it to another var tl What advantage does it provide I can just use timeline variable in subsequent code . Comment : its just another way to assign your timeline to a variable. . you can see that in practice here when i assign many timelines to multiple elements . Storing my timeline in a variable and then assign that variable to another var associated with each DOM element . . see this example codepen.io jonathan pen KdYqWo http : codepen.io jonathan pen KdYqWo Comment : I changed line 22 to el.animation tl and removed the assignment var t tl replaced it with just tl . The page still works the same . Both var tl and var t are actually pointing to the same TimelineMax object . It doesn t seem to offer any advantage to assign the same object to two different variables . see : codepen.io anon pen MKyWbG http : codepen.io anon pen MKyWbG PS : TweenMax chaining in your answer is misleading . You should make a note of it and strike it out . Comment : Sorry about that codepen sometimes parses javascript wrong due to their infinite-loop check which can cause it to be buggy .

I need to somehow apply a sharpen filter to origBitmap which I have successfully achieved using a ConvolutionFilter . The problem is after I ve ran the above tweenlite call then create a convolution filter and apply it to origBitmap it removes the initial saturation and brightness filters and just keeps the sharpen filter .. . .. . Is there a way to also incorporate the ConvolutionFilter in that TweenLite call above I ve searched quite a bit and found some guy made a class called TweenMan which was based around your class where ConvolutionFilter is incorporated : https : github.com danro tweenman-as3 .. . Answer : Nothing to do with TweenMax here since your code is the one making the mistake . This correctly removes all current filter and apply only one : .. . .. . Since filters property is either null or is an Array . To add a filter to the list you use array operation and reapply the array : .. . .. . EDIT : starting over since I think I understand what you are trying to do . You are avoiding creating the filter yourself and let TwennLite do it for you even tough you don t need to tween anything . Don t do that you are making everything harder for yourself . Instead create your filter that way : .. . .. . If you need to animate multiple filters remember that most tween engine can tween easily array values so you can just do that and then apply those array values to your filters . Comment : I ve tried that and it isn t working . I d rather not use TweenLite but the syntax for applying filters makes it so easy . I ve also tried doing bitmap.filters bitmaps.filters conv Comment : The tween is running at the same time and messing up the whole filters property . Not sure if TweenLite supports running 2 filters at the same time but either way you can easily do it yourself . I ll show you how if you need to . Comment : why is the tween time set to 0 Comment : I tried adding a timeout of 1 second to apply the convolution filter and no luck . I am simply using TweenLite because of its easy syntax of applying brightness saturation and contrast . I am looking into how to apply those effects without tweenlite because I think I could solve the problem that way . The 0 second tween time is because I don t need it to actually tween . Comment : then apply it directly in the filters property directly .", "Question : I m using tweenlite library to rotate move and zoom image . The problem is that I get 3D transformations on image but I would like to have 2D transformations . If tweenlite detects that there is browser which doesn t support 3D he will do 2d .

Answer : I think what you are looking for is called force3D http : greensock.com docs HTML5 GSAP Plugins CSSPlugin . Navigate to this link I shared and look for section named force3D on this page . Currently force3D defaults to a value of auto which means it will automatically decide when to use transform3d and when not to .

If my answer is not clear enough let me know . Comment : Okay . At this point I don t plan to use HTTPS so I am not sure what is a good point to use another layer which is Nginx cause post you have mentioned talks about Varnish as a cache as well . Comment : Using Nginx makes it easier to manage SSL also its better to cache the static content using NGINX Comment : Ok . So Nginx will be act as a cache and Varnish as a reverse proxy then If so Nginx will run port 80 for http no ssl Varnish port 80 for Nginx and 8080 for Apache and Apache port 8080 for Varnish and 80 for back end servers Comment : Nginx will be on PUBLIC IP : 80 Works as a cache for static content and to manage SSL if exist Varnish will be on LOCALHOST : 80 Receiving from NGINX and sending to Apache and Caching the dynamic-content PHP requests for exmple Apache will be on LOCALHOST : 8080 or 82 Which receives from Varnish and sending to the backend servers Comment : Thank you . I think I understand it . After verifiying Nginx was working Varnish was enabled . It look like everything is cache so age count is not increasing .", "Question : null .. . Answer : Ok so I have a Symfony 2 app that has been working ok . I now wish to deploy a varnish reverse proxy server in front of it . My app uses a slightly different approach from the usual in that I installed Suncat Mobile Detection Bundle where I detect a users device from within Twig and select which layout to extend e.g Layout.html.twig if mobile extends mobile.html.twig if desktop extends desktop.html.twig if tab extends tab.html.twig and all of this extend Base.html.twig . This is very convenient for me as I get a mobile tab and desktop optimized app easily . This comes at a cost however as I cannot cache the whole page as the mobile detection will not work my work-around was to set cache to 0 then render esi controllers for the page content and cache accordingly . This methods works flawlessly with the Symfony Reverse Proxy but now I want to try and if significant performance gain switch to Varnish . Currently I have Nginx ssl termination to Apache with symfony reverse proxy now I wish test and or switch to Nginx ssl termination to Varnish to Apache . I have bought a separate VPS for Varnish on which I can test irrespective of Nginx . I have read and followed many docs and it seems to work when I request static resources from the backend such as images I get a cache hit but my Symfony pages do not show cache hits on varnishstat .

Comment : Did you try to use the Vary cache-header with a corresponding custom header Such as Vary : X-User-Agent Accept-Encoding and then have e.g . X-User-Agent with 3 distinct values : desktop tab mobile . Let Varnish determine the user-agent also within the config and add it the vcl hash subroutine . This way you will have 3 distinct objects in varnish for the same url .", "Question : I have a reverse proxy server on which mod-security is configured to be used as web application firewall and varnish is for cache .

It does not seem to be requesting the new URL even after updating req.url and restarting the request . .. . Answer : This is not a definitive answer but here are some thoughts : .. . .. . 1 req.url holds only the path part of a URL but does not contain the protocol and host part of an URL . So it seems plain wrong to me when you assign http : rubygems.global.ssl.fastly.net latest specs.4.8.gz to req.url in vcl deliver and then restart . In my opinion the restarted request will not hit rubygems.global.ssl.fastly.net but still rubygems.org - the defined default backend . So I guess you would need to define a second backend rubygems.global.ssl.fastly.net and and set when you restart . You also need to do something like this not tested .. . .. . 2 retry and restart are different concepts in varnish 4 .. . .. . That is why bereq.retries always shows 0 . You need to look at req.restarts", "Question : I am always asking this question : why use Varnish instead of Symfony proxy Is there anything more than Varnish is a dedicated proxy Symfony is also managing other features so Varnish is better Or just because Varnish is written in C I didn t find any link where I can have a technical point about why Varnish proxy is better than Symfony proxy . Do you have any information to share with me about this .. . Answer : It outperforms Symfony cache by a large margin and also has-many features that Symfony s HTTP cache does not have . https : www.symfony.fi entry symfony-benchmarks-symfony-proxy-vs-varnish", "Question : Is it possible to set a cache-control header communicating with a reverse proxy to ignore query parameters in determining what is a unique uri or in short : validate a cache even if some query parameters have changed Sometimes query parameters have nothing to do with the rendering of the page at least from a server-side perspective . For instance all utm variables from Google Adwords . These are needed for the javascript on your page so you don t want to strip them away and redirect to a cached page but at the same time it would be advantageous not to treat two uri s which are basically the same but have different utm parameters as unique when communicating with a reverse proxy . An example : .. . .. . 1 . http : www.example.com search sort price .. . .. . 2 . http : www.example.com search sort price utm campaign shoes .. . .. . Is there anyway to tell the reverse proxy using the HTTP 1.1 spec i.e . some type of http header that it can just treat these two pages as the same .. . Answer : You can filter the query-string in vcl recv and there is also a Varnish module for that 1 . Also you have to keep in mind that query-string parameter order matters in this case 2 .. . .. .

I am running Varnish on port 80 and forwarding requests to nginx on port 8080 but when the user tries to login with OmniAuth and the Devise gem generates a url to redirect back to the server it thinks its on port 8080 which then the user will see . Is there any way to trick the Rails app to hard code the port as 80 I would think it s a bad practice or have nginx forward the request as-if it s running on port 80 Since I am not running a nginx proxy to the Rails app I can t think of a way to trick the port . Has anyone ran into this issue before if so what sort of configuration is needed to fix it Thanks in advance EDIT : Both nginx and Varnish are running on the same server . .. . Answer : Set up X-Forwarded-Port in Varnish . See this example http : www.cynapse.com community home cyn.in-users varnish-configuration and the other results from a Google search for varnish x-forwarded-port http : www.google.com search sourceid chrome ie UTF-8 q varnish+x-forwarded-port . You must also of course set up X-Forwarded-For and X-Forwarded-Proto . .. . .. . The headers X-Forwarded-For X-Forwarded-Proto and X-Forwarded-Port are a way for HTTP reverse proxies such as Nginx Squid or Varnish to communicate to the back-end HTTP application server your Rails application running in Thin or Unicorn who the user actually is and how the user actually connected . For example suppose you have Nginx in front of your Rails application . Your Rails application was booted with Thin and is listening on 127.0.0.1 : 8080 while Nginx is listening on 0.0.0.0 : 80 for HTTP and 0.0.0.0 : 443 for HTTPS . Nginx is configured to proxy all connections to the Rails app . Then your Rails app will think that any user s IP address is 127.0.0.1 the port is 8080 and the scheme is http even if the actual user connected from 1.2.3.4 and requested the page via https on port 443 . The solution is to configure Nginx to set the headers : .. . .. . and the Rails app should use these parameters instead of the default ones . The same applies for whatever reverse proxy you use such as Varnish in your case . Comment : This isn t a very descriptive answer . Do I need to setup X-Forwarded-For and X-Forwarded-Proto in nginx or Varnish Do I still have Varnish listen on Port 80 Comment : I have updated my answer with more description hopefully making the X-Forwarded-For system clear .", "Question : Here s the situation . I have clients over a secured network https that talk to multiple backends . Now I wanted to establish a reverse proxy for majorly load-balancing based on header data or cookies and a little caching . So I thought varnish could be of use . But varnish does not support ssl-connection . As I ve read at many places quoting Varnish does not support SSL termination natively . But I want every connection ie . client-varnish and varnish-backend to be over https . I cannot have plaintext data anywhere throughout network there are restrictions so nothing else can be used as SSL-Terminator or can be . So here are the questions : .. . .. . Firstly what does this mean if someone can explain in simple terms that Varnish does not support SSL termination natively . Secondly is this scenario good to implement using varnish and Finally if varnish is not a good contender should I switch to some other reverse proxy . If yes then which will be suitable for the scenario HA Nginx etc . .. . Answer : what does this mean if someone can explain in simple terms that Varnish does not support SSL termination natively .. . .. . It means Varnish has no built-in support for SSL . It can t operate in a path with SSL unless the SSL is handled by separate software . This is an architectural decision by the author of Varnish who discussed his contemplation of integrating SSL into Varnish back in 2011 . He based this on a number of factors not the least of which was wanting to do it right if at all while observing that the de facto standard-library for SSL is openssl which is a labyrinthine collection of over 300 000 lines-of-code and he was neither confident in that code base nor in the likelihood of a favorable cost benefit ratio . His conclusion at the time was in a word no . That is not one of the things I dreamt about doing as a kid and if I dream about it now I call it a nightmare . .. . https : www.varnish-cache.org docs trunk phk ssl.html .. . .. . He revisited the concept in 2015 . His conclusion again was no . Code is hard crypto code is double-plus-hard if not double-squared-hard and the world really don t need another piece of code that does an half-assed job at cryptography . .. . .. . .. . .. . When I look at something like Willy Tarreau s HAProxy http : haproxy.org I have a hard time to see any significant opportunity for improvement . .. . No Varnish still won t add SSL TLS support . .. . Instead in Varnish 4.1 we have added support for Willys PROXY protocol which makes it possible to communicate the extra details from a SSL-terminating proxy such as HAProxy to Varnish . .. . https : www.varnish-cache.org docs trunk phk ssl again.html .. . .. . This enhancement could simplify integrating varnish into an environment with encryption requirements because it provides another mechanism for preserving the original browser s identity in an offloaded SSL setup . is this scenario good to implement using varnish If you need Varnish use it being aware that SSL must be handled separately . Note though that this does not necessarily mean that unencrypted traffic has to traverse your network.. . though that does make for a more complicated and CPU hungry setup . nothing else can be used as SSL-Terminator or can be The SSL can be offloaded on the front side of Varnish and re-established on the back side of Varnish all on the same machine running Varnish but by separate processes using HAProxy or stunnel or nginx or other solutions in front of and behind Varnish . Any traffic in the clear is operating within the confines of one host so is arguably not a point of vulnerability if the host itself is secure since it never leaves the machine . if varnish is not a good contender should I switch to some other reverse proxy .. . .. . This is entirely dependent on what you want and need in your stack its cost benefit to you your level of expertise the availability of resources and other factors . Each option has its own set of capabilities and limitations and it s certainly not unheard-of to use more than one in the same stack . Comment : Hi this is a really good explanation . It is not just security but audit certification restrictions . So even if the plain text is on same machine it is visible to system administrator and even this is not acceptable . So whatever I ll use to route the traffic from within I need it to route SSL traffic as well . So I ll probably now use HAProxy for load distribution . Comment : Ok on a different note do you know if HAProxy can be used to distribute load based on Http s header parameters and or cookies Comment : @vish4071 yes HAProxy can inspect the payload and make the same routing decisions on HTTPS as HTTP as long as HAProxy terminates the SSL connection . It can re-establish SSL to the back-end so the unencrypted data is only within the HAProxy process which is different than what happens with Varnish but really no different than what happens inside the web server itself -- the encrypted data must be decrypted by the web server or it couldn t be processed by the application .", "Question : null .. .

This extension relies on Varnish config published on github . These are the features already implemented : .. . .. . 1 . Workable varnish config .. . 2 . Enable full page caching using Varnish a super fast caching HTTP reverse proxy . 3 . Varnish servers are configurable in Admin under System Configuration General - Varnish Options .. . 4 . Automatically clears only cached pages when products categories and CMS pages are saved . 5 . Adds a new cache type in Magento Admin under System Cache Management and offers the possibility to deactivate the cache and refresh the cache . 6 . Notifies Admin users when a category navigation is saved and Varnish cache needs to be refreshed so that the menu will be updated for all pages . 7 . Turns off varnish cache automatically for users that have products in the cart or are logged in etc . 8 . Default varnish configuration offered so that the module is workable .

Answer : Unless you are using one of the supplied vmods I would still install the source perhaps on a build machine and build your vmods there and then deploy your vmods to your production server . Or if you have something like an ansible script untar the source build your vmod move it into place and remove the source .

Option 1 would be my first option and option 2 the second .", "Question : I m trying to speed up my benchmark 3-tier web architecture and I have some general questions related to Memcache d and Varnish . What is the difference It seems to me that Varnish is behind the web server caching web pages and doesn t require change in code just configuration . On the other side Memcached is general purpose caching system and mostly used to cache result from database and does require change in get method first cache lookup . Can I use both Varnish in front web server and Memcached for database caching What is a better option scenario 1 - mostly write .. . scenario 2 - mostly read .. . scenario 3 - read and write are similar .. . Answer : Varnish is in front of the webserver it works as a reverse http-proxy that caches . You can use both . Mostly write -- Varnish will need to have affected pages purged . This will result in an overhead and little benefit for modified pages . Mostly read -- Varnish will probably cover most of it . Similar read-write -- Varnish will serve a lot of the pages for you Memcache will provide info for pages that have a mixture of known and new data allowing you to generate pages faster . An example that could apply to stackoverflow.com : adding this comment invalidated the page cache so this page would have to be cleared from Varnish and also my profile page which probably isn t worth caching to begin with . Remembering to invalidate all affected pages may be a bit of an issue . All the comments however are still in Memcache so the database only has to write this comment . Nothing else needs to be done by the database to generate the page . All the comments are pulled by Memcache and the page is recached until somebody affects it again perhaps by voting my answer up . Again the database writes the vote all other data is pulled from Memcache and life is fast . Memcache saves your DB from doing a lot of read work Varnish saves your dynamic web server from CPU load by making you generate pages less frequently and lightens the db load a bit as well if not for Memcache .

Answer : 1 var log syslog and var log messages are normally for syslogd . Varnish does not configure these they should already be setup . 2 I have always viewed Varnish messages in syslog var log messages .. . .. . 3 Core files are system specific . The first thing you need to do is enable core files on your system . You need to put ulimit -c unlimited in the varnish startup script . For an OS with init.d edit the etc rc.d init.d varnish file and add the above line to the start section . As to where the core files are stored you can use something like : .. . .. . echo tmp core e . p sudo tee proc sys kernel core pattern .. . .. . You are also probably going to want to build varnish from the source and turn on debug flags so that your core files have a symbol-table that you can look at . Running ulimit -c unlimited at the command-line and restarting Varnish is not going to work .", "Question : I have a Varnish 4.0.3 server on Centos 7.2 . Varnish has three backends configured . I am receiving intermittent 503 s from Varnish . I have pulled a tcpdump during a 503 event and I saw : .. . .. . Consumer makes request to Varnish .. . Varnish opens socket to backend . Backend responds in 500ms .. . Varnish sends a ACK FIN to the Backend . Varnish sends a 503 to the consumer . Backend sends a ACK FIN to Varnish .. . .. . The requests that fail do not fundementally appear different from requests that are succeeding . The failure rate is 1 per 20k requests . .. . Answer : Your client is using HTTP to communicate with Varnish . The HTTP response 503 represents mean The server is currently unable to handle the request due to a temporary overloading or maintenance of the server . The implication is that this is a temporary condition which will be alleviated after some delay . So this error is sent by the Varnish server indicating above reason . Regards Sudhansu" ] }

Comment : Can you share your inprovements Comment : Yes I am willing to share them . They were a lot of work . I have just emailed the gentleman behind white staruml fork about contributing them . .. . Answer : StarUML is the best open-source UML Tool .. . .. . After performing an exhaustive test on every free UML tool I could find I decided StarUML was the best . Unfortunately it s missing a few features : PHP Code generation reverse engineer and the ability to generate reports and estimates . BUT DON T STOP READING YET I went digging deeper and found out that StarUML saves project data in a single .uml file . This file is writing in plain old XML . Which means you can do whatever you want with it because it s in a simple predictable format . You could feed it to another application like a PHP application to generate all kinds of fun stuff like reports estimates put the model data into a database generate code for whatever language you want etc . This also means that you can write UML models without even opening StarUML for automation purposes because it s just XML . The other thing the StarUML interface can be extended through AddIns I looked in modules staruml-standard and discovered that most of the files were also in plain simple XML . I quickly wrote my own add-in and soon had a new menu item for generating PHP code . I also created a profile for PHP and added in a few tagged values one such being PHP Method Body an essential for round-trip engineering to preserve the method body by pulling it into the StarUML project to be written back out when you generate the code again . I still haven t actually hooked the menu items I created to any script but it looks really simple if you take a peek at how the staruml-standard addin does it . The XML menu item has a script attribute referencing a .vbs Visual Basic file . I looked at one of these .vbs files ConvCol2Seq.vbs which converts a Collaboration Diagram to a Sequence Diagram . Down at the bottom after all the helper functions the main code begins . In the first few lines of the main code the script creates an object with App CreateObject StarUML.StarUMLApplication and then the script has access to tons of features through the object named App . My next thought was There must be an API that will tell me how to use these objects Sure enough Google staruml api . The developers of StarUML knew exactly what they were doing . Create a solid tool and leave it wide open for expansion . Great work So as long as you follow the pattern in the XML it seems you can do whatever you want . I wonder if the API includes function for automatically generating graphics for a diagram If so I could batch generate graphic files for all diagrams then write a PHP app to automatically generate documentation reports and estimates with graphic diagrams included .

What are the pros and cons of both tools .. . Answer : I ve used the both original StarUML Unfortunately it was abandoned so long time because it was developed for a commercial program first by a company in South Korea.. . but the company went bankrupt . and StarUML2.0 I think WhiteStarUML is not very different from the original one . StarUML2.0 is much better to see - anyway it is prettier . It s undeniable . : and UI looks better . - But I felt it is a little bit uncomfortable when I draw some kind of diagrams.. . for me especially sequence-diagram . I guess it is because I m familiar with the original StarUML . What I want to say is I think StarUML2.0 can be a little bit unfamiliar for users who have been using StarUML1 for long time . But If you want to show your diagram in your presentation I recommend you to use StarUML2.0 . + Now staruml 2.0 is charged . Personal license is 70 . If you are a student you need to pay only 49 .

Comment : It d help if you can include the error message you get when you try to generate a collaboration diagram . .. . Answer : Back when these tools were built there was no standard for interchange of the diagrams -- only the metadata . If StarUML supports UML 1.4 1.5 you should be able to export an XMI file from ArgoUML to at least get the basics over but the diagrams will have to be redrawn ." ] }

Answer : Mustache itself is just a templating-engine it is not concerned with what URLs you have or how many PHP files you have or anything other than changing a template into HTML . For all the other things you have several options . The most straightforward is to have a single PHP file for every URL you want to handle . As you said this isn t ideal : .. . .. . I would suggest checking out a lightweight PHP framework . They handle routing mapping URLs to rendered pages and provide a lot more structure to your backend .

I m not that familiar with Mustache but according to the documentation https : github.com bobthecow mustache.php wiki Template-Loading by default loadTemplate needs to be invoked with the template string and not a template file name . Consider also configuring a FileSystemLoader for loading your templates : Comment : About the error you were right . Mustache template loader didn t work at all I tried to use file-get-contents on template too then template rendered correctly but the confusing part is data only shows up if I change person to person . Shouldn t I escape HTML On another more complex template it was exactly opposit result Comment : Your answer is right . About further problem it was unwanted comma in JSON file .

This works like a charm however in some cases I would also like to load regular partials . Is there a way to combine both the dynamic alias loader and the regular partial loading .. .

What am I doing wrong here Does Mustache provide a better way of doing something like this I am very very new to Mustache and have taken several tutorials just to get this far . Thank you for your help in advance .. . Answer : By default Mustache implementations escape HTML . They do this to protect you against malicious user-submitted content . You must use a separate variable syntax to unescape a string containing HTML . See Mustache Tags https : github.com bobthecow mustache.php wiki Mustache-Tags in the bobthecow mustache.php documentation : .. . .. . All variables are HTML escaped by default . If you want to return unescaped HTML use the triple mustache : name . .. . You can also use to unescape a variable : name . This may be useful when changing delimiters .

You could even have default sidebar partials by adding them to the sidebar block in the main layout just like there s a default title .

To use it you either have to add BLOCKS to the first line of any template with blocks in it or pass pragmas Mustache Engine : : PRAGMA BLOCKS to the Mustache Engine constructor to enable them globally .

I m not sure exactly what your issue is . In Mustache.php hinfo.artist name no spaces is correct syntax . In Mustache.js hinfo.artist name with spaces is correct syntax .

Comment : possible duplicate of Is it possible to use Mozilla Persona BrowserID with mobile apps http : stackoverflow.com questions 11451190 is-it-possible-to-use-mozilla-persona-browserid-with-mobile-apps .. . Answer : Persona BrowserID is not a general-puropse signature scheme . For that you might want to look at JSON Web Signature http : datatracker.ietf.org doc draft-ietf-jose-json-web-signature JWS for which there is library support in many languages . The navigator.id.request API https : developer.mozilla.org en-US docs Web API IdentityManager request does not provide a way to pass arbitrary data into the provisioning workflow so the standard Persona JavaScript would not be able to accomplish this . You would have to use customised JavaScript that provides the provisioning callback with custom data rather than a public-key object . If you get this far whether you can get the identity provider to sign arbitrary data will depend on how the IdP software treats the public-key argument . For example the Haskell persona library treats the public-key argument opaquely it will certify any arbitrary JSON Value see source https : github.com frasertweedale hs-persona blob v0.1.0.0 src Crypto Persona.hs L163 . On the other hand if the IdP software expects to parse a valid key object in the format generated by the JavaScript mediator code then you will not be able to sign arbitrary data . In conclusion : if you host customised JavaScript to pass arbitrary data to the IdP rather than a public-key and if the IdP s software treats the public-key as an opaque value then you can sign arbitrary data with Persona .

This is unfortunately useless for sign-in purposes because there s no way for your server to know whether an app requesting sign-in is friend or foe . The way around this problem is to run your persona code in an invisible iframe hosted on your server . Thus the iframe will have the correct origin and your server will know it s your app . The iframe and the app can communicate via postMessage . In the case of a packaged app sometimes called a privileged app your origin will be the origin declared in your webapp manifest . E.g . app : yourapp.yoursite.org . This gives you better assurance that the app is really yours but the truly paranoid may still wish to deploy the iframe trick . Hope this helps j Comment : So if I understand correctly - I should expose authentication process to my webpage thus run these javascripts on my webpage not directly on the device Comment : You would always run watch and request on the device . In the case where you don t have a privileged app I was suggesting that the code to run watch and request could live in an iframe served from your web page . But the first step is just to get watch and request working properly in a web page you visit from FirefoxOS or any other browser . Is that working Comment : Login with Persona to my site it works . Right now I managed to make it working - from mobile . Right now I have to sync signing up to mobile with singing app in the portal - I can login to my site with Persona and to my app .

This is how I understand the process : .. . .. . 1 . User clicks on the Persona login link .. . 2 . Ultimately the UI posts the assertion from the Persona verifier back to my site ie auth login .. . 3 . My site verifies the assertion .. . 4 . My site notices there is no user for the asserted email-address .. . 5 . What do I do next This is where I m a bit confused .

Once you sign in the site can make the local user just with the verified assertion . 2 . https : ting.com Seems to do it wrong . You need to sign up with Ting directly give a username password but afterwards you can authenticate with Persona . .. . Answer : You ve got the right idea . If you notice that the email you get doesn t map to an existing account then you show a sign up form to the user where they need to enter their name and anything else that your site needs . Or you do like I did in Zookeepr https : github.com zookeepr zookeepr : .. . .. . all profile fields are optional in the DB except for email .. . I immediately create a new account and log the user in when I get a new email .. . whenever someone logs in and some of their profile fields are missing they are shown a please enter this missing info screen before they can do anything else .. . .. .

I ve been working through this book http : chimera.labs.oreilly.com books 1234000000754 ch16.html which is fantastic btw and I thought I had everything working . All of the tests functional and unit but for some reason every time I hit the logout button I am immediately logged back in . I am using a custom authentication backend the one given in the book which uses Mozilla Persona as described in the book the chapter in the link . I have seen a few similar posts but none of the solutions helped . Behaviour : .. . .. . 1 . Logging in with bad credentials will continually refresh the page which appears to query Persona each time the Persona error : Persona says no . Json was : status : failure reason : audience mismatch : domain mismatch --I accidentally discovered this by visiting 127.0.0.1 : 8000 instead of localhost : 8000 . I do not know if Persona is queried each time or if the message is kept after each page refresh . 2 . The initial login appears to work correctly . The persona pop-up appears and goes through the steps before closing and reloading the page . 3 . After logging out the page will refresh sending post information and logging back in : 06 Nov 2015 21 : 25 : 20 GET accounts logout HTTP 1.1 302 0 06 Nov 2015 21 : 25 : 20 GET HTTP 1.1 200 795 06 Nov 2015 21 : 25 : 21 POST accounts login HTTP 1.1 200 2 The logout is redirected back to the root page . 4 . This behaviour is persistent through restarting the server and the web browser . If I stop the server and close the browser and reopen both entering in the web address again the page is already logged in . 5 . This behaviour also persists through different git branches . I am not sure when it started because the tests still pass but I know it worked previously . Every branch I checked has the same issue which makes me think it s something to do with the cache or installation . 6 . The behaviour also persists through removing all pycache migrations and the database itself . 7 . The behaviour persists through clearing the cache . EDIT UPDATE : I m still writing this so it s not technically an update...I had previously emptied the cache only for Today Firefox which had no effect however I just cleared everything and it seems to have solved the problem . I need to do more testing I ll update once I m sure . I do know that Persona says to use the ip over localhost but it doesn t seem to make a difference .

Comment : @TheBuzzSaw Doing what myself Comment : +1 I learned something about GLFW and it looks like it might be nice .. . Answer : I used both for some programs now . And I can tell you that I really prefer SDL over GLFW . I like the simplicity of GLFW but GLFW took out image loading entirely which I think is a real bummer . You do not want to write you own texture loader and looking for something that works and integrates well takes time . I also prefer having SDL events over callbacks because of the following reason . When I poll for events I can test them in a switch case block and from there I can modify local-variables . With callback functions this is not simply possible often global-variables are necessary which is dirty . GLFW simply misses the void on callback functions to pass the closure . The 2D rendering API of SDL can get pretty handy if you want to do simple operations on textures before putting them in video memory like putting all together into one big texture atlas . SDL supports : .. . .. . multiple mice .. . File Abstraction .. . Shared Object DLL loading .. . SDL ttf font rendering .. . SDL net network abstraction .. . .. . and still the library is small and modular . You can load just what you need .", "Question : I want to create an application where I draw on an window either windowed or fullscreen where I have the mouse grabbed but without intercepting any WM keyboard-shortcuts like Alt+Tab and I also need to be notified whenever the user enter leaves focus . Common applications like Google Chrome Firefox or gnome-terminal can handle this just fine going fullscreen with F11 but still having Alt+Tab but they do not grab the mouse . SDL has a notorious poor handling of this use-case : SDL WM GrabInput grabs the mouse but also intercepts WM shortcuts and SDL FULLSCREEN seems to have some sort of automatic grab by itself don t ask me why . A solution could be to write code for Alt+Tab myself but this sucks and doesn t help for other WM shortcuts like changing to another workspace . Another solution is to not call SDL WM GrabInput but instead fake a grab : just hide the mouse pointer with SDL ShowCursor and move it back to the center whenever the user moves . Which is ugly but in practice works - except of course for SDL FULLSCREEN because it grabs automatically unlike sane implementations . A fullscreen-capable SDL solution is this but that s still not what I want . I don t want to have hacks to enable and disable grab I want to grab the mouse but not grab the keyboard . So I am mad with SDL and want to see alternatives . I would like to use SDL but this is not necessary . This question http : stackoverflow.com questions 10916997 alt-tab-from-fullscreen-sdl seems to point out that what SDL actually does is to use XGrabKeyboard . By reading the man page it s not immediately clear to me whether you can grab the mouse without grabbing the keyboard I never used Xlib myself . I know how to make fake fullscreen with GTK that is of the Alt+Tab friendly gnome-terminal variety . I imagine that doing this coupled with mouse hiding and moving it back to the center fake grabbing could do the trick but this feels like too much duct tape . There must be a simpler way . Also I don t want to add GTK as a dependency but I m also not sure if making raw Xlib calls is a good idea . What s a good solution for this I need a Linux X11 solution but it would be nice for it to be cross-platform - I know this can be solved smoothly on Windows so perhaps there is a library that does exactly this . also I render with OpenGL but this is irrelevant .. . .. . PS : Perhaps I am having a bad understanding of this issue and I m not asking the right question so feel free to point out approaches I haven t considered . Comment : The question I cited http : stackoverflow.com questions 10916997 alt-tab-from-fullscreen-sdl in my opinion isn t really a duplicate since I m not looking specifically for a SDL solution . SDL is merely the library I m using right now . Comment : I just saw at Xlib API the XGrabPointer http : tronche.com gui x xlib input XGrabPointer.html function . So apparently Xlib has enough functionality for grabbing only the mouse without having to grab the keyboard . .. . Answer : I have been using Gtk and GtkGLExt for gaming on Linux these days e.g . my Ludum Dare entries . Here gtk.c Gist https : gist.github.com depp 4942294 is my code I have released it under the FreeBSD license . You can see the code I ve commented out for debugging window state changes . I should mention that this is part of a much larger framework which I use for things like Ludum Dare and I prefer it to SDL precisely for the same reasons that you mention : the resulting applications conform more closely to users expectations for native applications on their platforms Linux OS X Windows . Needless to say going this route is a lot of work . Raw X11 programming however is a real mess . I estimate that it would take me a couple weeks of solid programming and reading docs to convert my Gtk code to X11 code it s just not worth it for me but you may decide differently . Many hours just to eliminate a dependency that everyone has installed anyway The Gtk dependency is not actually that outrageous it s probably already loaded into memory anyway and the ABI for 2.x is very stable so it won t hurt binary compatibility . A big problem with X11 programming for games is that event-handling is a total mess . You can t easily poll for events . The Xlib interface is blocking so you have to use an arcane sequence of function-calls to read data check that there are events pending and then only read events from the queue if they exist otherwise your application will block until events appear . The xcb library is alternative to Xlib which is much better all around and supports a non-blocking interface but it doesn t play well with OpenGL . So you could try to mix the two or you could just use Gtk . Let me give you a snippet of the Gtk code for fullscreen : .. . .. . Just imagine how much work this would be with the X11 interface : figure out the size of the screen there might be more than one resize the window change the ordering so that it s on top of everything else change the decoration and then respond intelligently when the user switches virtual desktops . Blah Actually this describes how my code works on OS X but the APIs are much nicer . More than that if you re using X11 you ll have to learn how to react to the user in the expected way . X11 is from the 1980s . Gtk by comparison gives your application a swath of appropriate defaults from Gtk s UI designers . UI design is work . And remember : you can mix X11 with Gtk just fine . The summary : X11 programming is for programmers with lots of spare time . Notes : The GtkGLExt adds an annoying linker flag -Wl --export-dynamic . My build scripts remove the flag from pkg-config s output . X11 experiences : I think I spent about a week trying to get the whole thing working in X11 and I ended up following lots of dead ends in the process . Learn from my failures . Comment : Hey a big thank you I will take a look at your code . I agree that the benefits of simplifying programming quickly outweighs the drawbacks of adding a fat dependency like GTK . I would prefer a small library that does the same thing however . or to be honest I would prefer that SDL did this. . Comment : @darque : I also wish that SDL did this but I think the unfortunate reality is that SDL 1.2 s design is a relic from an earlier era . Maybe SDL 1.3 is better . And SDL is good enough for most people . There s definitely room for a modern replacement to SDL but since it s 2013 it would have to work well on Android and iOS which makes the undertaking so much more complicated . Comment : SDL 1.3 Hmm I heard that SDL 2.0 was going to improve this but I can t find it at Google except this roadmap http : wiki.libsdl.org moin.cgi Roadmap Mouse Input that cites improvements on mouse grab without elaborating . Comment : Anyway there is also the issue on whether you can do any of those WM tricks if you are setting to a different resolution and color depth . I can t say whether you code is setting video mode like SDL SetVideoMode does . F11-aware programs like Chromium does the WM trick of borderless-and-fill-whole-screen but doesn t set video mode . but it should work anyway like I could set mode by calling xrandr without affecting whether alt+tab works Comment : I think for a modern game it is usually inappropriate to change the video resolution . This is something you did in 2000 because the CPU couldn t push enough pixels but it s mostly irrelevant in 2013 when everyone has tragically underutilized graphics cards and LCD screens that look ugly when not run at full resolution . My advice is that if you have players with low-end systems from 2005 tell them to change the resolution themselves rather than do it in-game . SDL 1.3 and 2.0 are basically the same thing but 1.3 will have a compatibility layer for 1.2 .", "Question : I ve been working on a game that uses multiple audio tracks whose volumes are adjusted in realtime based on mouse motion . I m using SDl-Mixer for audio and Reactive-Banana for the game in general . The problem is that the tracks which have all been started at the beginning stop playing when the input-loop starts . The cause may be something else but I wonder if there s some strange interaction between SDL and Reactive-Banana that I don t understand .

Comment : What happens when you remove reactive-banana from the picture by replacing the last line with forever getMouseState print Comment : Same result .

Issues like that are often fixed by compiling with the -threaded compiler flag . If this is a Cabal project add .. . .. . to your Executable section . Comment : Tried it didn t seem to help . In fact the audio didn t start at all . Does this have to do with the fact that the FFI spawns its own thread I m wondering if I need to explicitly fork a thread for SDL . I m really inexperienced with FFI in haskell so I might have the wrong idea . Comment : Do I understand correctly that if you use -threaded then the audio will not start at all but if you don t use -threaded then it will at least start If so then this is an indication that SDL doesn t work well with concurrency . Which is probably unsurprising . Comment : SDL is designed to work with concurrency it has a thread library in it but there are of course some rules . Most SDL calls can only be made from the thread where SDL.init was initially called but having other threads around certainly won t cause an issue : Comment : @Apfelmus : I m actually not using any concurrency at this point not to my knowledge but yeah that s what happened .", "Question : The documentation of SDL does not seem to mention much about color spaces .

If you are on SDL2 you should request the capability by calling SDL GL SetAttribute SDL GL FRAMEBUFFER SRGB CAPABLE 1 during init but if you are on an earlier version of SDL it seems that right now graphics drivers do not care if you request it beforehand .", "Question : What are the pros and cons to each It seems they serve the same purpose .

Snippet from GLFW s FAQ http : www.glfw.org faq.html why-yet-another-opengl-library : .. . .. . ...SDL is too large for some people and has never had OpenGL as its main focus . .. . We therefore believe that there is room for a lightweight modern library for managing OpenGL contexts windows and input . See Related Toolkits and APIs https : www.opengl.org wiki Related toolkits and APIs .. . .. . Bugs .. . .. . Here are a couple of bugs that currently exist in both GLFW and SDL : .. . .. . home button doesn t work on some keyboards https : github.com andrewrk genesis issues 1 .. . keyboard-shortcuts ignore keyboard layout https : github.com andrewrk genesis issues 2 .. . .. . Neither of them have fixed it yet but the maintainer of GLFW has participated in the issues and planned to fix them while I have seen no response from SDL . By the way do not use GLEW .. . .. . Instead use libepoxy https : github.com anholt libepoxy snippet from libepoxy s README : .. . .. . GLEW has several issues : .. . .. . Doesn t know about aliases of functions There are 5 providers of glPointParameterfv for example and you don t want to have to choose which one to call when they re all the same . Doesn t support GL 3.2+ core contexts .. . Doesn t support GLES . Doesn t support EGL . Has a hard-to-maintain parser of extension specification text instead of using the old .spec file or the new .xml . Has significant startup time overhead when glewInit autodetects the world . User-visible multithreading support choice for win32 . .. . The motivation for this project came out of previous use of libGLEW in piglit . Other GL dispatch code generation projects had similar failures . Ideally piglit wants to be able to build a single binary for a test that can run on whatever context or window system it chooses not based on link time choices . .. . We had to solve some of GLEW s problems for piglit and solving them meant replacing every single piece of GLEW so we built piglit-dispatch from scratch . And since we wanted to reuse it in other GL-related projects this is the result . Comment : @andrewrk Are you really sure about Glew OpengGL version support the Sourceforge news list http : glew.sourceforge.net seems to tell that OpenGL 4.5- contexts are supported since version 1.11.0 .

So the question is : Is it possible to Draw 2D things with SDL over the 3D scene or do I need to draw them with opengl Because I ve experienced that if I create a SDL renderer the OpenGL scene will disappear and be overdrawn by the SDL renderer . Comment : I would just do it in OpenGL using an orthographic projection pretty straight forward . .. . Answer : IIRC OpenGL has functions for drawing 2D elements . You could render the 3D to a texture and then render 2D over it . If you must use SDL you ll need a method to copy an OpenGL texture to an SDL surface texture .

I used SDL too but i think it has a bunch of functionallity that is not used and the one that is needed it comes on a different installation about jpeg loading audio net etc - of course glfw doesn t have them either .", "Question : First off I m relatively new to this . I m looking forward to picking up both SDL2 as well as SFML2 libraries for game dev . and other stuff . Now I know for a fact that both SDL2 and SFML2 are capable of creating OpenGL enabled contexts through which OpenGL graphics programming may be done . But online I ve read discussions wherein people said something to the effect of SDL 1.2 is software accelerated SDL2 and SFML2 are hardware accelerated by default . I know that software rendering is graphics using CPU alone . While Hardware rendering uses graphics cards pipeline . So my question is with regards to these game libraries : .. . .. . Part 1 : when someone says one is software hardware acc.by default what does he mean Is it that my guess if say SFML2 is hardware acc . by default even basic 2d graphics are done by it using hardware rendering as the backend pipeline to do it even if I didn t explicitly do any hardware-rendering programming in the code Part 2 : And if that is true is there any option within these libraries to set that to software acceleration rendering Part 3 : Which of these 2 libraries SDL2 vs SFML2 has better overall performance speed Thanks in advance for any answer and apologies if you found the question dumb . .. . Answer : Cannot say anything about SFML but almost sure things are very close but for SDL it is as you say . In SDL1 2d drawing implemented as blitting directly on display surface and then sending this surface to display - so mostly software although minor hw acceleration is still possible . SDL2 have SDL Renderer and textures which are GPU-side images or render targets and any basic drawing that uses renderer may be accelerated by one or another backend . Which backend will be chosen depends on system your program runs and user settings - e.g . it would default to opengl for linux d3d for windows but still can use opengl opengles for android ios etc. . .. . .. . You can use software renderer either by explicitly calling SDL CreateSoftwareRenderer https : wiki.libsdl.org SDL CreateSoftwareRenderer or hint https : wiki.libsdl.org SDL SetHint SDL to use software https : wiki.libsdl.org SDL HINT RENDER DRIVER driver or even override it by setting SDL RENDER DRIVER environment variable . If you intend to use opengl for 3d graphics - then you just ignore all that and create window with opengl context as usual and never use SDL Renderer . Comment : By the hint and SDL RENDER DRIVER parts did you mean simply using the software rendering substitutes meant for software rendering OpenGL D3D calls on that system eg . Mesa driver for OpenGL Swiftshader for D3D Comment : Sorry I cannot understand your comment . Basically it requests SDL to use different implementation for all rendering functions e.g .

Comment : @TheBuzzSaw Doing what myself Comment : +1 I learned something about GLFW and it looks like it might be nice .. . Answer : I m not familiar with GLFW but I never liked SDL because it tries to take over too much responsibility from your program and force you to write an SDL application rather than an application that uses SDL . On the other hand if you re a beginner or if your program benefits from not having to think outside the SDL box that might be a plus . Comment : I have to agree with this . GLFW is simple and robust and does only the necessary stuff to help programmer to build the application as he wants . SDL is not so straighforward and simplistic but it certainly has useful features too . Comment : Exactly what about SDL takes over too much responsibility from your program I use SDL rather extensively I have never had this feeling . Comment : I can t say for sure whether it still does this but originally on Windows it used define main .. . to rename your main and run its own code prior to main . This of course broke properly factored programs where the translation-unit containing main had no knowledge of using SDL . Comment : Hmm I don t think I stated that very clearly - what I meant to say is that the define main hack completely failed if the file containing main did not include SDL.h and in fact a program that s just using SDL as a component rather than being an SDL app probably would not have include SDL.h in the file with main .", "Question : Is there a good library to use for gathering user input in Linux from the mouse keyboard joystick that doesn t force you to create a visible window to do so SDL lets you get user input in a reasonable way but seems to force you to create a window which is troublesome if you have abstracted control so the control machine doesn t have to be the same as the render machine . However if the control and render machines are the same this results in an ugly little SDL window on top of your display . Edit To Clarify : .. . The renderer has an output window in its normal use-case that window is full screen except when they are both running on the same computer just so it is possible to give the controller focus . There can actually be multiple renderers displaying a different view of the same data on different computers all controlled by the same controller hence the total decoupling of the input from the output Making taking advantage of the built-in X11 client-server stuff for display less useable Also multiple controller applications for one renderer is also possible . Communication between the controllers and renderers is via sockets . Comment : I deleted the answer that led to the clarification above.. . I think the clarification needs to stay but it covers enough that my pseudo-answer which could ve been a comment can be deleted entirely . .. .

I am trying to build a video-player using both FFmpeg and SDL . I am viewing my video on SDL Surface . My player is working fine .

Comment : Show us your code : Comment : i am doing this : SDL BlitSurface Bmpsrc NULL screen rect SDL Flip screen where Bmpsrc and screen are SDL Surfaces .. . Answer : SDL 1.2 does not have an API for moving windows . SDL 2.0 has better support for multiple windows and window management in general . See http : wiki.libsdl.org SDL SetWindowPosition .. . .. . To do this with SDL 1.2 you ll need to use platform-specific calls using the window handle . You can get that with SDL GetWMInfo . If you just need to set the initial position of the window so it is centered then try this before SDL SetVideoMode :", "Question : I am newbie to SDL and developed a small SDL 2.0 project trying to run setup under dosbox but it crash . Comment : Back in the DOS days there were no OS standards for device drivers - they gave you access to the underlying hardware and that was it not putting M code between your code and an 8MHz 8086 was seen as a good thing . That meant for example writing handlers in your code for every printer you supported SDL uses OS standard drivers to abstract out hardware-acceleration etc for video cards which DOS does not have . Since it s open-source you could in theory write a DOS version of SDL but without hardware-acceleration in an emulator it might be really slow .. . Answer : No you cannot do that . If you want to run your app with SDL forget about DOS : DOS is not on the list of supported platforms http : wiki.libsdl.org Installation Supported platforms .", "Question : Is there a way to get initial position of mouse in SDL 2.0 I try to get mouse coordinates by SDL GetMouseState mouse x mouse y however I get the result I expected only after using the function SDL PollEvent and also I can t see a value other than 0 0 if the mouse has not been moved at least once since begining of the program.Although I don t check SDL MOUSEMOTION and connect SDL GetMouseState to it I get mouse coordinates only when mouse is moved.So what s wrong Or is SDL GetMouseState suitable to do so Edit : Why Why is there no any answer Comment : Which OS are you using SDL2 on Comment : I run via Windows 7 . .. . Answer : The SDL updates the position of the mouse internally in SDL PrivateSendMouseMotion http : hg.libsdl.org SDL file 54c06b0f65d9 src events SDL mouse.c l191 which is called by various mouse related functions in the same file . These functions are called in the event-loop processing function WIN WindowProc http : hg.libsdl.org SDL file 54c06b0f65d9 src video windows SDL windowsevents.c l287 in response to the mouse events dispatched by Windows . Thus if you do not move the mouse no event is dispatched and the SDL does not know where the mouse is . The solution is to wait for a mouse event before requesting the position and to find a workaround until this event .", "Question : I have been learning about SDL 2D programming for a while and now I wanted to create a program using SDL and OpenGL combined .

For the second option i m unaware of how to do this using the elasticsearch.js api so I would have to do it another way and I can t find an example of this online .", "Question : I am trying to add Elasticsearch HTTP access to the Titan ES client https : github.com thinkaurelius titan blob titan10 titan-es src main java com thinkaurelius titan diskstorage es ElasticSearchIndex.java L334 using JEST https : github.com searchbox-io Jest . titan-es only supports ES local and transport TCP mode . But I would like to support communication over ES HTTP interface . That would allow client libraries like titan-es to use AWS Elasticsearch https : aws.amazon.com elasticsearch-service as an indexing backend which only provides a HTTP S interface . See this post https : groups.google.com forum topic aureliusgraphs tVSw7UiyEyg for more information . I am looking for some feedback on the approach I am considering so far : .. . .. . 1 . Create a new class ElasticsearchHttpClient that implements the org.elasticache.client.Client interface . The new class will use the JestClient as it s internal client . This way it will communicate with ES over HTTP . The new class will likely extend ES AbstractClient to reduce the methods that have to be implemented to : admin settings execute threadPool and close . 2 . Add a new enum HTTP CLIENT to ElasticSearchSetup .. . 3 . Ensure that the connect method on HTTP CLIENT returns an instance of Connection which contains proper values for node and client . The client member would be an instance of the new ElasticsearchHttpClient class . 4 . Ensure that ElasticSearchIndex.interfaceConfiguration method retrieves the correct instance of Connection containing the new ElasticsearchHttpClient if the INTERFACE is configured as HTTP CLIENT . From that point on the rest of the code should continue to work over the new protocol . Does that sound like it should work The 1st step is my biggest concern - I am not confident that I can implement all Client methods using the JestClient . I also asked this on the Titan mailing list https : groups.google.com forum topic aureliusgraphs 70 AAPASlzo and Elasticsearch forum https : discuss.elastic.co t how-to-create-a-new-elasticsearchhttpclient-class-implementing-org-elasticache-client-client-to-enable-es-applications-to-run-against-aws-elasticsearch 39348 u ingo jaeckel . .. . Answer : I ve posted an answer in the Titan mailing list https : groups.google.com d msg aureliusgraphs 70 AAPASlzo nd60lM3WAAAJ . What you d need to do from a Titan perspective is implement the IndexProvider interface . My guess is that it isn t feasible to make Jest look like a full Elasticsearch client . .. . I think you would use JestHttpClient -- you don t need to implement the Jest interface . IndexProvider has methods to create drop mutate query an index which you should be able to do over HTTP . Check the Elasticsearch HTTP documentation to see if you can do all the required methods on IndexProvider with JestHttpClient . .. . There s already an ElasticSearchIndex implementation of IndexProvider which does NODE and TRANSPORT . You re trying to add an HTTP or JEST option . So you might consider shoehorning your changes into ElasticSearchIndex but I m not sure how well that will work out since the 2 existing impls are both full Elasticsearch clients . Perhaps consider creating a separate ElasticSearchHttpIndex implements IndexProvider if it s cleaner .", "Question : null .. .

First note that if you macroexpand the call yourself you can see that with-html-output establishes macrolet bindings such as str htm ftm esc .. . The htm macrolet takes no argument except a body and expands into a with-html-output form which has the same parameters has the lexically enclosing with-html-output macro .

You macro is expanded and produces an htm : script .. . form . 3 . Then the macrolet is expanded to produce an inner with-html-output .. . form . 4 . The inner with-html-output is expanded and processes : script .. . . You have to choose if you prefer to use macros or functions here . Functions are generally not inlined and can easily be redefined at runtime . Macros can in theory be expanded at runtime too but in most implementations and default configurations you have to recompile whichever function depends on a macro . You could also let the macro call an auxiliary function . Comment : Thanks for the detailed explanation For me I ll now stick to cl-who and use more functions .

On the other hand to suppress the result string and only see the document as written out you can do something like this : Comment : Today when I tried it again it worked for some reason .

Any help will be appreciated . .. . Answer : There are JUnit 3 vs 4 runner differences that may be the cause you don t mention JUnit and dbUnit versions nor how dependency managing them . And different tooling has different running default requirements e.g . Maven defaults to only running classes as tests with class name suffix of Test . Note that it is not required to extend a dbUnit class I don t and not doing so should eliminate the encountered problem . Just further down that page you mentioned are two sections describing how : .. . .. .

Using no parent class : http : dbunit.sourceforge.net howto.html Database setup with no parent class .. . .. . And combining both is what I ve done for years - have my own parent test class for common stuff and then DI or instantiate the desired DBTestCase usually PrepAndExpectedTestCase . Comment : Thanks It worked using a IDatabaseTester . :", "Question : Spring Test helpfully rolls back any changes made to the database within a test method . This means that it is not necessary to take the time to delete reload the test data before each test method . But if you use the @BeforeClass Junit annotation then that forces the data loader to be static . A question that is explored here : http : stackoverflow.com questions 1052577 why-must-junits-fixturesetup-be-static .. . .. . If the data initialization method is static so must the data connection methods and the data source..and on and on...forcing everything to be static...which won t work . At which point I ask - what good is Spring Test s ability to rollback changes when you have to delete reload the test data anyway for every test .. . Answer : We use DBUnit in conjunction with Spring Test extensively . But we do not use the DBUnit functionality to delete data at the end of the test . We put a bunch of DBUnit inserts for our test data in the @Before method to initialise the test . Then when the test is complete we let the spring rollback functionality bring the database back to its original state . The biggest problem we have with this is that the DBUnit data has to be loaded before each test which can be a major performance hit . Most of our tests using DBUnit are read only testing the behaviour of the application based on certain predefined behaviour . So we have a habit of creating master tests that then run all the fine grain tests in a batch within the same transaction . Comment : Well that s bad practice . What do you think of the checked solution", "Question : For example after I setup a datasource to the actual database and use @DatabaseSetup to set it to a state which of the following happens 1 DBUnit connect to the actual database delete everything insert records specified in @DatabaseSetup test the cases and then roll back . 2 DBUnit somehow create an in-memory database based on the datasource setup the in-memory database . Nothing is changed in the actual database . 3 Magic . How does the DBUnit work Thanks . .. . Answer : DBUnit does exactly what you ask it to do . If you connect it to the real database then yes it will be acting on the real database . If you tell it to act on an in-memory database then that s what it will do . If you get it to do a CLEAN INSERT then it will wipe all of the data in all tables specified in the dataset you re asking it to load it ll then load the dataset then it will remove the loaded dataset . The data it wiped at the start will not be put back in-place . If you re using DBUnit for testing you generally would not point it at the real i.e . production database . Instead you d create a copy of some sort and point it at that . That copy could be a real instance of your DB something in-memory it could be populated with dummy-data or a copy of the real data .", "Question : I m wondering if there is any way to specify for example tomorrow as date in the DBUnit XML dataset . Sometimes code logic is different for dates in future and dates in the past and I want to test both cases . For sure I can specify something like the 5th of November 2239 and be sure that test will work till this date but are there more elegant way . I haven t yet faced such situation during my Java development but once I had experience when code logic was different for one day before dates two days before dates and more than two days before dates . In this case the only possible solution to write database driven test is to insert relative dates during data-import . Are there any facilities provided by the DBUnit for this .. . Answer : You can use add of Calendar http : java.sun.com j2se 1.5.0 docs api java util Calendar.html add 28int 20int 29 to define dates in the future and using this in relationship with datasource for JUnit . I doubt that this would work with DBUnit s XML format . May be you create your own TestCase which extends from DBTestCase and implement getDataSet method . Comment : Yes I know how to calculate relative day in Java . It looks like I really need to parse dataset and calculate dates manually .", "Question : I have a simple spring project and try to use spring-dbunit https : springtestdbunit.github.io spring-test-dbunit to do some services tests .

Answer : You need to provide a way to create your schema before running your unit tests . The way DbUnit works is by putting your database in a known state before running the particular test . If you have a RDBMS installed you should have already the database created but if you are using an in-memory database more likely for this matters you must provide a SQL script or some other way to be able to create the schema for you when the in-memory database is started . Have a look here https : bitbucket.org vadimvera spring-jdbc this may helps . Comment : Yes you have right . I had to init DB schema first .

Answer : am I supposed to create a new database only for tests so my DBUnit can point to it It is a better approach to do so as it eliminates multiple problems . how would I manage the structure synchronization between my original database and the one for tests You don t mention tech in your persistence stack such as Hibernate Spring Spring Boot Spring Data Flyway LiquiBase etc . to suggest more of how to implement this .

An in-memory embedded database for its speed such as Apache Derby automatically started just before launching tests . 2 . Create tables in schema using Hibernate DDL gen from annotated entities . 3 .

Minimal dbUnit data for each test . Comment : Great answer thanks Yes I am using hibernate-entitymanager and let s say I am using liquibase to manage mysql database . So the question that comes to my mind is. . Is it safe to use Hibernate DDL gen to create the schema and its tables for the in-memory database or should I find the way to use the same liquibase for both databases Comment : If the team correctly manages the entities then it s probably very safe to use the Hibernate DDL gen . However if the entities don t have all the needed annotations then your best choice is the LiquiBase configuration . Since the team has made the effort to write the LiquiBase files and LiquiBase has the master definition and used for production I would use it instead of the Hibernate DDL gen . This way tests use the same configuration as dev test prod environments . This is very helpful and important . Comment : Jeff I have another doubt .

Thanks Edit : I believe using class AbstractJUnit38SpringContextTests by Spring is the way to go since it is the latest class made for JUnit 3.8 to help us in such cases . Comment : Afaik if you use @Transactional and the Spring JUnit Runner Spring should automatically recognize that it s in test mode and rollback the transactions.. . Comment : Yes but as I understood the Spring JUnit Runner is for JUnit 4 and I m depending on JUnit 3.8 instead . Comment : Ah yeah my bad . Never needed the abstract-class for spring there but as far as the documentation says it seems to be the way to go.. . .. . Answer : We dropped support for JUnit 3.8 in Spring Framework 4.0 . However if you are still using Spring 3.2.x you can extend from the AbstractTransactionalJUnit38SpringContextTests http : docs.spring.io spring-framework docs 3.2.15.RELEASE javadoc-api org springframework test context junit38 AbstractTransactionalJUnit38SpringContextTests.html base-class . Since you re using DbUnit you may also be interested in the third-party DbUnitTestExecutionListener https : springtestdbunit.github.io spring-test-dbunit . Regards .. . .. . Sam author of the Spring TestContext Framework Comment : Thanks . I just need a way to change the Spring Context file location now . Unfortunately my test case already extends class ServletTestCase of Apache Cactus which works with JSFUnit to run my test case on the Tomcat running in eclipse . So I cannot extend a second class such as AbstractTransactionalDataSourceSpringContextTests maybe which allows me to change the context through overriding a method named getConfigLocations . Glad I got your attention :", "Question : I am new to automated testing and dbUnit . So I would appreciate your advice . I am going to create a test suite that will run the following way : .. . .. . create an in-memory H2 database .. . run DDL scripts to create tables .. . run dbUnit to insert initial data let s call it STATE0 that will be used by all tests . run tests .. . .. . Till there it looks nice for me but what I don t understand is how do I revert the database to the STATE0 after a test run and changed the data Can I do it with dbUnit Or with something else Should I recreate the database before each test Simple not commiting transactions in tests is not appropriate for me because the tests will eventually run more than one transaction over may be more than one database-connection . .. . Answer : DBUnit can do the work four you automatically if you write your @BeforeClass @Before and @After methods properly . E.g . in our project using Derby one such test case looks like .. . .. . This code puts back a subset of the DB schema to the state defined by MyDataSet.xml after each test . Note that as @Pascal commented the reset may not always be full - if a test modifies a table which is not in the dataset it won t be affected by the @Before @After methods . Comment : Does this really reset the DB I mean if my test insert some data in the table FOO and if MyDataSet.xml doesn t include FOO FOO won t be reseted right Comment : @Pascal you are probably right . Being human it is always advisable to double-check that if I am running tests which involve table FOO that table is actually included in the dataset . Comment : ter I agree with that . It s just that the nitpicker in me was not fully convinced by the phrasing of the last sentence : +1 anyway . Comment : @Pascal in our profession it is almost always better to nitpick in advance than to be sorry afterwards : - So thanks for your comment I updated my answer to make it hopefully clearer . Comment : I find it very clear and fully accurate now .", "Question : In a nutshell .. . .. . My command-line Java application copies data from one datasource to another without using XA . I have configured two separate datasources and would like a JUnit test that can rollback data on both datasources . I use DBUnit to load data into the source database but I cannot get this to rollback . I can get the target datasource to rollback . My Code .. . .. . Given this config.. . .. . .. . and this code.. . The problem as I see it is that @TransactionConfiguration only states the target datasource for enabling a rollback . DBUnit is being passed dataSourceA explicitly and is picking up the default transaction manager named transactionManager I m not sure how which has not been told to rollback . Question .. . .. . How can I tell both transaction managers to rollback Can I use a single transaction manager when my datasources do not support XA transactions Note : The application does not require a transaction manager on dataSourceA when running in production as it will only be read-only . This issue is for my tests classes only . .. . Answer : A possible workaround would be to introduce a helper bean annotated as @Transactional transactionManagerTarget and leave your test annotated as @Transactional transactionManager configuring both with defaultRollback true . Your test would then have to call the helper bean which in turn would call your service bean under test . This should cause the transaction around your service to roll back then the transaction around DBUnit . It s a bit messy though . Other possible approaches : .. . .. . Using an in-memory database such as H2 instead of your production database- you could configure this to drop all of its data when required . Allow DBUnit to commit and have a compensating transaction in your tear-down method to clear the data out . Comment : I tried factoring out a helper bean but this does not help the siutation . Somewhere under the hood DBUnit will not rollback when there are multiple transactionManagers . I m going to accept your answer for using HSQL as the way forward however in my case I m still stuck because I use Sybase to create a temporary table on this datasource and the syntax is not compatible with HSQL .", "Question : null .. .

My problem is i don t need any entity as i am connecting to other database and saving the data from there to the temp table in our application database using PreparedStatement.If i create entity class the test case runs fine . Is there any way through which DBUnit will consider the table for which entity class is not there . .. . Answer : dbUnit does not use entity classes it directly uses JDBC . The dbUnit error is table does not exist and dbUnit does not create tables . Your application test setup creates the tables from the entity classes so without the entity the table does not exist . For needed tables without entities test setup must create these tables . For ease you may want to just put the entity in the test classes folder . Another option is to run DDL that creates the table s before running all tests . Comment : Jeff thanks for the response so it means if i will create the entity class in test folder it will not cause any problem .", "Question : Spring Test helpfully rolls back any changes made to the database within a test method . This means that it is not necessary to take the time to delete reload the test data before each test method . But if you use the @BeforeClass Junit annotation then that forces the data loader to be static . A question that is explored here : http : stackoverflow.com questions 1052577 why-must-junits-fixturesetup-be-static .. . .. . If the data initialization method is static so must the data connection methods and the data source..and on and on...forcing everything to be static...which won t work . At which point I ask - what good is Spring Test s ability to rollback changes when you have to delete reload the test data anyway for every test .. . Answer : Spring Test and DbUnit is two excellent frameworks . But it doesn t make sense to combine them . Since Spring Test execute a rollback on the connection it cleans up afterwards while DbUnit cleans up and insert test data in the @Before method . Use Spring if you re not dependent on any dynamic data and dbUnit otherwise . Comment : I find DBUnit s ability to load a database-table from XML to be convenient .

In production code the transaction is started by a controller the service itself does not know anything about a transaction . So here is my test : .. . .. . What I found out is that if I annotate the NewsService with @Transactional propagation Propagation.REQUIRES NEW the test works fine however it is not the same as in production mode . @Transactional propagation Propagation.REQUIRED is not sufficient as the DbUnit-Spring-test opens a transaction by itself and the latter assert fails as the transaction is not committed yet . How can I achieve that a transaction is committed BEFORE the last assert is executed .. . Answer : As mentioned in the documentation .. . .. . http : springtestdbunit.github.io spring-test-dbunit .. . .. . If you have configured DBUnit tests to run using the are DbUnitTestExecutionListener and are also using the TransactionalTestExecutionListener you may experience problems with transactions not being started before your data is setup or being rolled back before expected results can be verified . In order to support @Transactional tests with DBUnit you should use the TransactionDbUnitTestExecutionListener class . .. . .. . And to initiate transaction you have to annotate your test method or class with @Transactional annotation like this . Comment : Thanks for your reply but it s not about the @ Transactional . It s about commiting a transaction manually AND DIRECTLY AFTERWARDS assert that the database is an an expected state . The @ Transactional is not necessary as the database is resetted before each test . Comment : OK may be you need to handle manually commit by flushing the session as you are already inside a global test transaction of dbunit SessionFactory.getCurrentSession.flush Comment : Or moviing the saving part into a new testSave method by wrapping the method by a Transactional requires new may be it will commit after leaving the method Comment : No success so far .

I believe this works because by default mockito tries to use the apps cache directory but I never run an activity so I suspect the directory is never created by the OS Comment : You can also call the following as given here - code.google.com p dexmaker issues detail id 2 http : code.google.com p dexmaker issues detail id 2 .. . getInstrumentation .getTargetContext .getCacheDir", "Question : I am trying to get Mockito 1.9.5 rc1 working in my Android tests using Robotium .

Answer : I encountered the same problem attempting to use mockito 1.9.5-rc1 . The dexmaker page notes that you need 1.9.5+ http : code.google.com p dexmaker for this and apparently RC1 doesn t cut it . Mockito 1.9.5 appears to have just been released days ago http : code.google.com p mockito wiki ReleaseNotes so it should show up shortly in Maven Central .

CMake is slow to generate makefiles http : stackoverflow.com questions 26701628 cmake-is-slow-to-generate-makefiles .. . .. . My project is made up of a top level CMakeLists.txt which uses add subdirectory to add various subprojects for individual library and executable components . For a given component the CMakeLists.txt contains something like : .. . .. . I can build just the contents of that directory using : .. . .. . If I modify the CMakeLists.txt in the sub-directory which I ve been doing a lot as part of a migration from pure Makefiles to cmake then run make it correctly re-runs cmake to update the configuration as-if I d run make rebuild cache . However I notice that it in fact reconfigures the entire project . What I really want is for cmake to be clever enough to know it only needs to regenerate the Makefile in the current directory and sub-directories . Is there a better way to structure a cmake project to achieving this I see some people use project for each CMakeLists.txt in each sub-project . In general is this a good idea Alternatively Additionally is there some way to speed up the generation step of cmake currently I have 60s+ .. . .. . Bonus points if you want to discuss why cmake itself should or shouldn t be able to run in parallel imagine a cmake -j .. . .. . .. . .. . I ve added the meson-build tag as a modest bounty alone hasn t yet attracted enough attention to warrant an answer . Its this kind of problem that might cause people to switch to build systems to meson-build assuming it doesn t have similar problems or something similar . It is possible that the correct answer is it can t be done without modifying the source to cmake . To earn the bounty though I require an explanation in terms of how cmake works and or where it is flawed . .. . .. . Clarification : It is the generation step that is slow in my case . The configure itself is quick enough but cmake hangs for a quite a while between outputting -- Configuring done and -- Generating done . For a full cache rebuild I run : .. . .. . under the hood this runs : .. . .. . I presume -B is a synonym for --build neither option is described correctly in the documentation @todo report bug -H is the root of the source directory not the same as --help as the docs would have you believe .. . .. . Its fast to get to the output of Configuring done but slow from there : E.g . If edit a single CMakeLists.txt file in a subdirectory then run make -n it runs : .. . .. . --check-build-system is another undocumented option . The effect is the same - regenerate the whole build-system not just the current subtree . There is no difference in behaviour between an in source and and out of source build . If I run a trace e.g . : .. . .. . The majority of time spent seems to be spent on or between open access unlink calls . The length of each task is quite variable but the huge number of them builds up . I have no idea what the Labels.json and Labels.txt files are about something internal to cmake .. . .. . 1 run : .. . .. . another run of the same command : .. . .. . Note the ninja generator is much faster though still not brilliant E.g . Note that the project is not quite ready for ninja yet as there are errors like : .. . .. . and .. . .. . to be resolved . This question is really about why the Makefile generator is slow . I m not sure if the problems ninja shows are useful hints here or red herrings . .. . .. . Building cmake with more optimisations does not help . Based on my trace output it and the output of time it is unlikely that it would . The user time and therefore time spend within the cmake code itself is quite low . see e.g . What do real user and sys mean in the output of time 1 http : stackoverflow.com questions 556405 what-do-real-user-and-sys-mean-in-the-output-of-time1 Here s what I tried for completeness : .. . .. . Actually using a more optimised cmake does make the configure part faster but in my case it is the generate part that is slow . It would appear from the timing that this step is somehow I O bound . .. . .. . I decided to investigate Florian s idea that using memory insteam of file stream for temporary files might make a difference . I decided to try the easy route and hacked cmake to write .tmp files to a ramdisk instead . I then went the whole hog and tried generating the build-system on on the ramdisk .. . .. . I was very surprised to find this makes no difference at all to the wall clock time : .. . .. . Similarly with ramfs : .. . .. . What could be happening here I was guessing sub-processes but I can t work out which sub-processes are consuming the wall clock time if any of them are . They look to be very short lived . .. . .. . for completeness here is some output from perf cmake built with -fno-omit-frame-pointer : .. . .. . And perf report -g graph -no-children : Comment : project modifies neither parsing flow nor makefile generation flow . It just adds several CMake variable s definition . Comment : I had a similar problem and rebuilding CMake itself with a lot more optimization options then the normal distributions did reduce my configuration time from about 20s to less then 1s . Which host system do you use Another alternative would be to divide a big project into sub-projects using ExternalProject Add see e.g . my answer here http : stackoverflow.com questions 33443164 cmake-share-library-with-multiple-executables 33448011 33448011 but this would increase the initial configuration step duration . Last there is always the possibility of binary delivery pre-compiled libraries . Comment : And did you see CMake Performance Tips https : cmake.org Wiki CMake Performance Tips Because I think this being more a configuration step issue then having a problem with the generation step just writing the files is normally pretty fast . Can you please try the Investigation profiling methods https : cmake.org Wiki CMake Performance Tips Investigation.2Fprofiling methods Simply because the configuration step duration mainly depends on what you do in your CMakeLists.txt files . Comment : I thought about externalProject add but really the subprojects are not external . They are part of the same source tree . In particular they share the same configuration and are strongly coupled as in your answer . Is it considered good modern cmake practice to use ExternalProject Add as a workaround in this case Comment : Note that I have looking at the performance tips and using trace strace . I ve even poked into the source of cmake a little . Nothing obvious leapt out and I haven t had a chance to delve deeper . .. . Answer : Turning my comments into an answer .. . .. . Answering this isn t easy because there are so many aspects that define CMake s configuration and generation steps duration besides what you actually do in your CMakeLists.txt files it s e.g . your host system your toolchain and which CMake version distribution you are using . So I try to concentrate on the specific questions you have . Rebuild Rewrite makefiles for just a subdirectory .. . .. . For the start : Using add subdirectory is good for structuring your CMake code . But you have to keep in mind that you can always change global CMake properties in a subdirectory and that targets inside those subdirectories can have cross-dependencies . So what does CMake do considering the I have touched one CMakeLists.txt file in a subdirectory case discussed here : .. . .. . If a CMakeLists.txt file is changed it goes through the complete hirarchy of CMakeLists.txt files again and rebuilds the build environment again in memory . Now it temporarily recreates all the necessary build make files and checks if they defer from the existing ones see cmGeneratedFileStreamBase : : Close https : github.com Kitware CMake blob master Source cmGeneratedFileStream.cxx L162 .. . If a file has changed it replaces the existing one with the new one .. . .. . This behavior is necessary because any makefile can change even when only a subdirectories CMakeLists.txt file has changed and it was optimized to prevent unnecessary rebuilds during the actual make step from touched makefiles . Is there some way to speed up the generation step of cmake .. . .. . So yes it does temporarily rewrite all makefiles which could be slow and no you can t minimize this while using add subdirectory to only the changed subdirectory . Maybe one possible performance optimization for the future in CMake s own code would be to use memorystreams instead of filestreams for the temporary files . Edit : @BruceAdams tested this by using a RAM disk for the generated makefile environment with no effect . And yes the CMake generated cmake check build-system rule does almost the same as the rebuild cache rule and yes the used -B -H and --check-build-system options are CMake internal command-line options and therefor undocumented even if often referred to on StackOverflow e.g . in one of my answers here http : stackoverflow.com questions 33917454 cmake-how-to-specify-the-version-of-visual-c-to-work-with . What helped me to speed-up the configuration generation was to rebuild CMake itself with a lot more optimization options than the normal distributions and using a 64bit toolchain instead of the 32bit versions currently still distributed . Edit : Here are some test results using the CMake test script found below with 100 subdirectories libraries on my Windows PC always using the same MSYS environment but different CMake compilations of the same CMake source code : .. . .. . 1 . Official CMake 3.2.2 version : .. . .. . time -p cmake -G MSYS Makefiles . . .. . .. . .. . real 43.93 .. . user 0.00 .. . sys 0.03 .. . .. . .. . 2 .

To summarize I see two main influences : .. . .. . 1st : The configuration step can be speed-up by going for a 64bit version and optimize for your processor platform you would certainly have to find a common base -march .. . or -mtune .. . https : gcc.gnu.org onlinedocs gcc-4.9.2 gcc i386-and-x86-64-Options.html for all your project s build PCs . 2nd : The generation step can mostly be speed-up by searching for possible file I O bottlenecks outside of CMake . In my case telling the antivirus software to not check the toolchain and build directories each time I read-write to those was really speeding up things . Remark : I confirmed @BruceAdams test results that the compilers auto-vectorization https : gcc.gnu.org projects tree-ssa vectorization.html default for -O3 or -Ofast is not able to do much about CMake source code s ability to run in multiple processes on multiple cores . Is there a better way to structure a cmake project to achieving this .. . .. . Yes if you e.g . know that a certain sub-tree of your CMake script code just generates a library and has no dependencies you could put that part in an external project by using ExternalProject Add . And yes having had similar concerns http : stackoverflow.com questions 31512485 cmake-how-to-setup-source-library-and-cmakelists-txt-dependencies regarding large CMake projects this is seen as a good modern cmake practice see also references below .

And then - after the first cmake . . and make calls - doing : Comment : Thanks for the answer . I m not sure I m fully convinced by arguments to use externalProject Add for internal libraries . I will try it out though and see if the performance justifies the extra complexity . Essentially that means that add subdirectory does not scale and yet this is one of the few places where cmake s language is quite nice . auto vectorisation will not make your code multi-core multi-threading or multi-process automatically . There is hope for that with parallel STL and execution policies but you still have to write you code in suitable fashion . Comment : I don t think you ve actually solved my problem or completely answered the question but rather than let the bounty go to waste I will award it on the basis of effort . I ll try with external project add when I have more time and if that works out I ll accept the answer . Comment : @BruceAdams Thanks . So I will also try to add some results on the CMake recompilation part . And sure the auto-vectorization can only do so much . And I ll give it a try and rewrite my test code to use externalProject Add for the libraries and add the measurement results also . Comment : @BruceAdams I ve added my recompilation test results . Going for 64bit and - as I ve already done for my build environment paths in the past but had not measured the influence so far - selectively disabling my antivirus software had a significant speed-up effect 85 less for the initial configuration step . I ll try to add some numbers for the externalProject Add usage in the coming days ." ] }

Thanks for your help Marc B .", "Question : PHP PDO ODBC doesn t seem to be able to store NVARCHAR characters UTF-16 without some manual encoding . This seems like a pretty commun bug all around the internet and no one seems to have a definitive solution . How to reproduce the bug .. . .. . 1 . Try to insert the following japanese characters using PDO : It means hello .. . 2 . The following will be stored in your database : .. . 3 . Then retrieve it via PDO and print it on the screen you will get : .. . .. . It s not so bad but it s not good either . PHP works but when you have other applications that are not in PHP that access that information from your database they will get the wrong string : . Ideally you would want to have everywhere . The symptom .. . .. . It seems that PDO doesn t have any notion of NVARCHAR aka characters that are encoded using 16 bits . In fact everything that you pass to or retrieve from SQL SERVER via PDO will be by chunk of 8 bits . How to prove it Here it is : .. . .. . 1 . You start with your japanese string . You first have to know that PHP consider string as binary and that if it s set like that it will store them in UTF-8 . So if we look at the binary representation of you will get E38193E38293E381ABE381A1E381AF which is also the binary representation that SQL SERVER will give you for . depends on your collation .. . .. . 2 . Next let s put it into UTF-16 because that s the format of NVARCHAR . utf16 string mb convert encoding UTF-16LE .. . .. . The following will-change the binary representation in PHP of to 533093306B3061306F30 which is exactly the binary representation of in SQL SERVER NVARCHAR . 3 . Next try to save it in SQL via PDO and you will get the following : S0 0k0a0o0 .. . .. . The SQL SERVER binary representation of S0 0k0a0o0 in VARCHAR is 533093306B3061306F30 which is also the binary representation of in NVARCHAR . A dirty solution .. . .. . You can use the following to save and retrieve unicode data in SQL SERVER via PDO ODBC but it s ugly.. . .. . .. . 1 . You want to transform the data into exactly the same binary representation that SQL SERVER NVARCHAR will store it .. . .. . mb convert encoding UTF-16LE .. . .. . 2 . You want to receive it as a binary on SQL SERVER side and then transform it to NVARCHAR . @binary VARBINARY 40 SELECT @string CONVERT NVARCHAR 20 @binary .. . .. . 3 . At this point you have in your database . To retrieve it you want to resend it to PHP as a binary .. . .. . 4 . Once you get the binary in PHP PHP will already have transform it into a hex string.. . So you want to convert the hex string into a binary and then change the encoding from utf-16 to utf-8 .. . .. . result mb convert encoding hex2bin string UTF-8 UTF-16LE .. . .. . And you will be back with your when you echo it to your webpage . Basically that s what the SQL driver should be doing for me instead of me doing it manually . Did I forgot to configure something or I have to do it manually .. . Answer : No I don t think you forgot to configure anything . In fact your explanation is the best I ve found so far regarding the long-standing issues between PHP and Microsoft ODBC drivers . Those issues are especially puzzling given that the PDO ODBC page http : php.net manual en ref.pdo-odbc.php says : .. . .. . On Windows PDO ODBC .. . is the recommended driver for connecting to Microsoft SQL Server databases . However on Windows they also offer PDO SQLSRV http : php.net manual en ref.pdo-sqlsrv.php which actually does appear to work correctly . So it seems that PDO ODBC doesn t have any notion of NVARCHAR rather than PDO as a whole . Similar problems arise when trying to use PHP with Microsoft Access ODBC if Unicode characters are involved .. . .. . Conclusion : PHP support for ODBC continues to be a bit of a mess at least where Microsoft databases are concerned .", "Question : null .. .

Out of curiosity can you reproduce with all-static query as well I mean this this .. . Answer : This is probably not what you want to hear but this has all the hallmarks of a bug in PHP s ODBC driver for PDO which is not heavily used as PHP programmers tend to favour open-source databases like MySQL SQLite Postgres over commercial offerings or in the underlying SQL server driver which is poorly supported in Linux for similar reasons though if odbc works then it s probably not the underlying driver . If you try to do the exact same tasks except using sqlite : : memory : as the DSN all your examples work . This makes it highly unlikely that you re doing anything wrong unless MS Server has some really weird non-conforming SQL syntax of which I m not aware . Your examples work fine for me with SQLite when ATTR EMULATE PREPARES is both enabled and disabled . All I think you can realistically do is file a bug report https : bugs.php.net report.php and hope somebody picks it up . You may be in for a long wait though . As for practical solutions to your problem your options are either a switch to a DBMS that PHP supports or b resort to SQL string construction instead of prepared statements and be ready to accept the burden of avoiding SQL injection attacks https : xkcd.com 327 yourself . This should be considered a last resort though Using PDO : : quote http : php.net manual en pdo.quote.php may help but I d also make sure your data is very thoroughly validated as well . I know it s not an ideal solution but if you must use MS SQL and can t wait for the PHP team to bugfix it then I don t really see that you have much of a choice . Or there s option c which is use odbc functions instead if they work . Of course if you want to use OOP style then you ll have to implement your own class that wraps the procedural odbc functions in OO methods so that could potentially be a lot of work .

Fortunately .. . .. . It has a patch http : git.php.net p php-src.git a commit h 186ffcb72c982b0235761bdd6388ff1c36d79568 that was first included in the 5.6 release : .. . .. . This bug is also referenced in 61777 https : bugs.php.net bug.php id 61777 and is still present in the latest stable release of the 5.5 branch . I see two tickets exist for this problem already and I m just submitting these changes via github as a reminder that this is a serious problem for anyone using PDO ODBC on the x64 builds . What is wrong with your PHP s shipped PDO ODBC By looking at one of those recommended patches : .. . .. . We see the only thing that s changed is SDWORD 16-bit signed integer which is substituted with new ODBC type SQLULEN that is 64 bits in a 64-bit ODBC application and 32 bits in a 32-bit ODBC application http : www.unixodbc.org doc ODBC64.html . I believe committer wasn t aware of colsize data type only since in the very next line SQLLEN is defined properly . What should I do now 1 . Upgrade to PHP version 5.6 .. . 2 . Stick with odbc functions as a working solution . 3 . Compile a PHP v5.5.9 with provided patches . 4 . Build your own PDO wrapper as recommended by @GordonM Comment : Wow 64824 is spot on the bug I ve got too . I covet thy Google-Fu because I never came close to finding that . I m afraid that the patch was built for a slightly different bug referenced in 61777 but I m still eager to try . It might take me a couple days to get the time to spin up a test vm to build custom PDO with that patch but I m excited thanks Comment : I compared that patch to PHP 7.0 related source files and can say you are going to do it right . @JeffPuckettII Comment : Today I installed a fresh ubuntu-16.04 on a vm with php7 and confirmed that this issue doesn t exist . I edited your answer to include this option . Tomorrow I will spin up another vm with php5 and compile with the patch to fully confirm your answer and if it s successful then I will happily accept your answer . Comment : I did not add Upgrade your PHP to the list since I guessed you are not thinking about this option . So if you are able to do it you are totally fine . A PHP version 5.5.x does not come with this issue . @JeffPuckettII Comment : CONFIRMED . I cloned the php source checked out release 5.5.9 compiled and installed to verify the bug . Then I cherry-picked that commit recompiled and installed and totally verified that fixed this bug .", "Question : There is a column url nvarchar 200 not null .. . .. . Returning error : .. . .. .

ODBC Driver 11 for SQL Server .. . sql-server-2012 .. . centos-x64 6.4 Comment : Well seems to be a bug . Now I m trying to compile PHP with a patch I found . .. . Answer : Having done a fair bit of research into this it seems pdo-odbc is buggy on 64-bit architectures : it s built with 32-bit SQLLEN and SQLULEN sizes . Microsoft s driver used to be built this way which is probably why PHP followed suit . MS have since started to follow the ODBC spec properly but apparently PHP hasn t . The patch referenced in the question fixes one such problem in the PHP source but seemingly not all such problems . Using the MS driver and a patched PHP I was still unable to run prepared statements . I actually found the same problem when using Easysoft s driver and talking through the issues with them discovered that pdo-odbc is the culprit . They were able to provide me with a 64-bit driver built using 32-bit sizes and that works fine . Until 64-bit PHP is patched to use 64-bit SQLLEN and SQLULEN sizes it looks like the best Free solution is to use 32-bit PHP and ODBC drivers .

Is that pattern completely stupid My temporary solution is to SELECT the column names from the system.schema columns table and to strings.Join all of that to my SELECT query .. . Thank you very much for your help . .. . Answer : I m not familiar with the gocql library but it sounds like you may be running into a combination of not repreparing your statements and CASSANDRA-7910 https : issues.apache.org jira browse CASSANDRA-7910 . Whenever a request is Prepared like what is being done in Select from where date in it sends a request to cassandra which responds with the column metadata for that table so when you get a response to a query back from cassandra you know what columns are available to look for . It looks like gocql has a feature called Automatic query preparation which may be treating your request as a prepared-statement . When you alter a table the prepared-statement does not get updated on your client-side so really the only way to fix this is to reprepare your statement not sure if you have that level of control from gocql . However this still doesn t work since there is a bug in cassandra CASSANDRA-7910 https : issues.apache.org jira browse CASSANDRA-7910 where it does not return the new columns since it is itself caching the prepared-statement on it s side and not invalidating it when the schema changes . This issue is fixed in 2.1.3 coming soon it may be worth trying this against the cassandra-2.1 branch in git to see if that resolves your issue . It s not an abnormal pattern to alter your schema when your application is running so this is a scenario that should work but unfortunately doesn t . I d look into seeing if there is a way to reprepare statements in gocql . I see there is a stmtsLRU var in cluster.go . If you could somehow get to that you could invalidate prepared statements . If there isn t a way to do this would be good to open up an issue against gocql as you can reprepare statements again in other drivers . I know that the java driver allows you to do this but gives you a warning . I suppose this could be a big difference between gocql and the other drivers in that in the other drivers you explicitly use a prepared-statement object where-in gocql it gets handled for you automatically in the library . With the cassandra bug outstanding I think you should stick to not using prepared statements and instead make queries like : SELECT FROM api counters WHERE date total", "Question : I have a table with a tuple column that is made up of an int64 paired with a uuid : .. . .. . and I can currently set the field using a cql statement like : .. . .. . and I pass in 2 variables as arguments an int64 and a gocql.UUID . Instead of moving 2 variables around everywhere I want to put these in a struct something like .. . .. . then use a Marshaller to pass these into the UPDATE statement .

If so how can I do this I can t figure out how - I was trying to mimic https : github.com gocql gocql blob master marshal test.go L935 but I m getting errors where I can t set the fields in the struct cannot refer to unexported field or method proto Comment : The error you get is because you are trying to use from a different package a variable or method that is not exported i.e . they do not start with Upper case . But beside this I don t know cql so I can t help . Writing Proto instead of proto may or may not fix your problem . .. . Answer : As you mentioned you are getting the following error : .. . .. . cannot refer to unexported field or method proto .. . .. . This means you need to export your fields inside the struct and that means beginning with a capital letter in Go . So your struct should be : .. . .. . Then it should work . Comment : Yea so I think the gocql lib needs an update in order to support this . Comment : Um well no : I don t think gocql can do anything about this . This is more like Hibernate requiring your classes to have public setter and getter methods . So YOU need to make first letters of your struct fields in capital letters . Using capital letters is THE way you make your struct usable by external code and I don t think any way around this exists .", "Question : I came across this weird behaviour while trying to implement some counters for my application .

Thank you very much for your help . .. . Answer : Thanks Andy for your help . At first I thought that considering what you told me I would rather do a SELCT column name on the system.schema columns sometimes and refresh it when I alter my table . I would just then strings.join the columns in my SELECT FROM api counters . It worked but if I had 2 different instances and one would update the schema and the other would receive a GET request this one would not know the new column still . And then I rearranged my ideas and found out that there was obviously an other way of doing that and I simply change for this schema : CREATE TABLE stats dev.api counters date text description text all counter PRIMARY KEY date description and I am updating the field based on the description I am expecting .

Answer : Plain answer is no getting number 100 in your example means knowing the result-of SELECT count FROM table which is a perf killer query .

Each data load from cassandra is small but many . I should be scalable so I can put in more app containers - like in Kubernetes they have pods .

Answer : Please see : .. . .. . https : github.com kubernetes kubernetes blob release-1.0 examples cassandra README.md .. . .. . for a tutorial of how to run Cassandra on Kubernetes . You will also need to add-in best practices like snapshotting the databases to persistent-storage and other such things . and why do you say that Kubernetes is expensive Google Container Engine only charges the cost of the VMs for small clusters and you can deploy open-source Kubernetes yourself for free Comment : Thanks . Hov would you devide the workload in a pod . Like 3 app containers to 3 cassandra nodes plus one seed node in pod", "Question : My scan is not updating its destination variable . I sort of got it working with : .. . .. . But I don t think it is working the way I want . Both log messages are the exact same Existing obj 0 0 0 0 0 0 0 0 0 0 0 0 Spaces are string fields . Is this because of the heavy use of reflection to generate a new object In their docs it says I should use var ValueName type to define my destination but I cannot seem to do that with reflection . I realize this may be silly but maybe even just pointing me in the direction for further debugging this would be great . My skills with Go are quite lacking .. . Answer : What is it you want exactly Do you want to update a variable you pass to Execute If so you have to pass a pointer to Execute . And then you only need to pass reflect.ValueOf incrementedValue .Interface to Scan . This works because reflect.ValueOf incrementedValue is a reflect.Value https : golang.org pkg reflect Value holding an interface the type of your parameter which holds a pointer the pointer you pass to Execute and Value.Interface https : golang.org pkg reflect Value.Interface will return a value of type interface holding the pointer the exact thing you have to pass Scan . See this example which uses fmt.Sscanf https : golang.org pkg fmt Sscanf but concept is the same : .. . .. . It will print 1 from main as the value 1 is set inside Execute . If you don t want to update the variable passed to Execute just create a new value with identical type since you re using reflect.New which returns the Value of a pointer you have to pass existingObj.Interface which returns an interface holding the pointer the thing you want to pass to Scan . What you did is you passed a pointer to a reflect.Value to Scan which is not something Scan expects . Demonstration with fmt.Sscanf : .. . .. . This will print 2 . Another variant of Execute2 is that if you call Interface right on the value returned by reflect.New : .. . .. . This Execute3 will print 3 as expected . Try all examples on the Go Playground http : play.golang.org p DpuUcN3Af3 . Comment : I am accepting a value of any type incrementedValue and I am just trying to create an uninitialized new variable of the same type to give to the bindQuery.Scan . I want a second one because I go through and compare all their fields later on . I haven t tested what you posted but I wanted to give a little more detail on why I am trying to do what I am . Essentially the end goal is get the object from the database compare with the incrementedValue then update the database with the changes between the two . Fairly simple until you want to make it really dynamic . Comment : @electrometro Then my Execute2 and Execute3 might be feasible to you . Also a link-to try my codes on the Go Playground http : play.golang.org p DpuUcN3Af3 is included at the end of my answer . Comment : The second example was exactly what I needed . It was a long night and as soon as I seen that this morning it made perfect sense . Thanks", "Question : I m trying to insert a map value into my Cassandra database .

Answer : As stated by the documentation http : synopse.info files html Synopse 20mORMot 20Framework 20SAD 201.18.html TITL 86 current version of the main framework units target only Win32 Win64 systems under Delphi and in a preliminary state Windows or Linux under FPC . So you can run a Server on those platforms . But you can write a Client on all Delphi supported platforms by using some dedicated cross-platform client units and generate some code to consume the server ORM and SOA content . To write an OSX or Mobile client using FMX for the UI do not use regular SynCommons.pas mORMot.pas units but the dedicated units as available in the CrossPlatform sub-folder . The documentation is pretty detailed about it . See also this sample https : github.com synopse mORMot blob master SQLite3 Samples 27 20- 20CrossPlatform 20Clients MobileClient.dpr and the associated generated client unit https : github.com synopse mORMot blob master SQLite3 Samples 27 20- 20CrossPlatform 20Clients mORMotClient.pas . Comment : Mormot s documentation too big . I read demo with calculator but it s calculator .

Did you read the chapter I quote in my answer Publish the wrappers generator on the server compute your cross-platform client unit then use it directly . For RAD consumption you would have to fill a TDataSet with the data by code or fill a string grid or other components with code from the objects returned by the client unit . Comment : Damned if you do damned if you don t . There s not enough documentation . There s too much documentation . Comment : @Arnaud . It s interesting components but I don t understand . General advantages of Delphi is mobile developing . Main advantages of you tools is powerful data-access . Why I can t open demo with multi-tier server and mobile client Comment : and JSONToClientDataSet component is included in mORMotMidasVCL", "Question : mORMot Framework www.synopse.info http : www.synopse.info have add support to WebSockets on pack there is also a demo about WebSockets sample 31 . In this sample the client send a message to server and this reply with a new message to client . I d like use this library to do this : .. . .. . 1 . The client send message to server and send also the IP address without waiting message from server . .. . 2 . The server can send message to single client by IP address .. . .. . Note : the IP address is used only to identify the client . I can use also a unique name . Something like a LAN chat between clients and server . I don t understand how edit the sample n . 31 to do it . This sample is based on interface . Comment : The link-to the framework should be synopse.info not .com .. . Answer : No need to store the IP or whatever low-level implementation parameter by the way the IP would not be able to identify a connection in an unique manner : several clients may share the same IP . In the mORMot framework asynchronous callbacks are implemented via interface parameters . On the server-side each instance of this parameter would be in fact a fake class instance linked to the input connection able to call back the client via its interface methods . This is a pretty straightforward way of implementing callbacks - in fact this is a good way of implementing SOLID callbacks on the server-side and the mORMot framework allows to publish this mechanism in a client-server way by using WebSockets . So you first define the callback interface and the service interface : .. . .. . Then on the server-side each call to IChatService.Join would subscribe to an internal list of connections : .. . .. .

In case of high numbers of messages the framework is even able to gather push-notification messages into a single message to reduce the resource use . The following method will be called by the server when a client callback instance is released either explicitly or if the connection is broken so could be used to unsubscribe to the notification : .. . .. . On the server-side you define the service as such : .. . .. . Here the optExecLockedPerInterface option has been set so that all method calls would be made thread-safe so that concurrent access to the internal fConnected list would be safe . On the client-side you implement the IChatCallback callback interface : .. . .. . Then you subscribe to your remote service as such : .. . .. . If you compare with existing client-server SOA solutions in Delphi Java C or even in Go or other frameworks this interface-based callback mechanism sounds pretty unique and easy to work with . Of course this work from Delphi 6 up to XE7 and also under Linux thanks to FPC or CrossKylix .

I wish to establish a connection and query the database directly via SQL without using the ORM Object-relational mapping features of mORMot .

Answer : In short : it is better to use the SynDB.pas layer over SynSQLite3.pas via its SynDBSQLite3.pas classes since it will allow your code to work in the future with any database accessible via OleDB ODBC or even direct access e.g . for Oracle . For instance using a variant for holding column data : .. . .. . So for your question read the SynDB-related part of the mORMot documentation and all the related blog articles http : blog.synopse.info tag SynDB . Those classes are used by the ORM but you can use those without the ORM . To start with there is a TQuery wrapper in SynDB.pas which works very well with SQLite3 and allow classic code-level programming . But there is not 100 RAD direct access with those units . Just some TClientDataSet fillers . This was not their purpose : they want fast and direct access to the DB in code not via the UI plumbing .

Answer : I just tested it with Delphi Seattle 10 and the ODBC driver from http : ftp.postgresql.org pub odbc versions msi psqlodbc 09 03 0400.zip - with no problem . Ensure your PostgreSQL server has been defined to run on the same port as expected by the source . Edit the 5433 value into 5432 if you used the default port-number . Being paranoid I try to always change the default port which reduces network-scan attacks at least from fast scan . I never use port 22 for ssh nor 5432 for PostgreSQL . Sorry for the inconvenience .

We want to offer our customers the possibility having their databases in cloud hosted in our server .So clients are written in Delphi server is a http IOCP server written also in Delphi from mORMot framework for dbs we use Firebird embedded .

Practically can I call FDManager.AddConnectionDef . . while other pools are in use .. . Answer : AFAIK Firebird embedded does not have any connection . As its name states it is embedded within the same process so there is no connection pool needed . Connection pools are needed when several clients connect disconnect to the same DB over the network whereas here all is embedded and you would have direct access to the Firebird engine . As such you may : .. . .. . Define one connnection per Firebird embedded database .. . Protect your SOA code via a mutex aka critical section per DB . In fact mORMot s HTTP IOCP server would run the incoming requests from a thread pool so ensure that all DB access is safely made . Ensure you use at least Firebird 2.5 since the embedded version is told to be threadsafe only since revision 2.5 see the release notes http : www.firebirdsql.org en firebird-2-5-release-description . Instead of FireDAC consider using ZDBC Zeos in latest 7.2 7.3 branch which has nice features together with the native mORMot SynDB libraries http : synopse.info files html Synopse 20mORMot 20Framework 20SAD 201.18.html TITL 126 . Comment : Agree to disagree - connection pools are used to to facilitate acquiring a resource when normally creating establishing a new one will take time and or resources . Even attaching a local database file to the process like fbembed.dll does will take some time and resources - SQL privileges will be checked separate buffers will be allocated per every attachment even it s the same process and the same database file FB 2.5 . So connection-pooling apply here . Comment : Defining connections and protecting them with a critical section is not connection-pooling So why invent the wheel when there is available a tested one . Even if your scenario seems simple because it s only one connection per database I think I need at least two of them because sometimes one client can acquire the connection for a longer period of time because has to synchronize a bigger change log since it was last time online . Anyway your solution is good one because it has one critical section per db and Firedac will have one critical section per all databases .", "Question : I m in process of upgrading our client-server ERP app to multi-tier .

Practically can I call FDManager.AddConnectionDef . . while other pools are in use .. . Answer : Looking at Firedac sources seems that all about adding connection definitions and acquiring connections in pooled mode is thread-safe . Adding a connection definition or matching one is guarded by a TMultiReadExclusiveWriteSynchronizer and acquiring a connection from the pool is guarded by a TCriticalSection . So answers : .. . .. . 1 . I don t have to create all ConnectionDef s before server starts serving requests . 2 . Yes I can call safely FDManager.AddConnectionDef . . while other pools are in use . Using Firedac acquiring a connection for any of those databases will be guarded by one TCriticalSection . The solution proposed by @Arnaud Bouchez presents a more grained access by creating one TCriticalSection per database and I think will scale better but you should be aware of a bug when using multiple TCriticalSection especially that all will be initiated at once : .. . .. . https : www.delphitools.info 2011 11 30 fixing-tcriticalsection .. . .. . In that article present a very simple fix for this bug . Comment : Since you are using mORMot you can use the TSynLocker record or the IAutoLocker TAutoLocker interface class which fixes the TCriticalSection bug allows to protect a whole method in one call and uses the padding space to store some values which would be protected by the lock .

Answer : FireDAC is more helpful than some other frameworks in that when things go wrong the exception messages often say how to fix the problem . So in your case given that the message says you can drop component TFDPhysXXXDriverLink into your project the thing to try first would be to drop the relevant DriverLink component onto your form datamodule .

Answer : Versions .. . .. . Symfony 2.8 .. . Sonata core 2.3 cannot upgrade it to 3 as it produces too much collateral damage .. . .. . .. . .. . Original Issue .. . .. . Basically after upgrading from symfony-2.7 to 2.8 one of the sonata core filter form types sonata type equal flips its option list key-value . This is due to some version detection in the EqualForm class where it erroneously performs an array flip on the choices array . Line 62 https : github.com sonata-project SonataCoreBundle blob 2.x Form Type EqualType.php the comments say from 2.7 but it only seems to hit 2.8 .. . .. . .. . .. . So to try to fix this I thought I would extend the original form class and fix the issue . No matter what I do I cannot get Sonata to use my custom type class . I ve looked at all sorts of posts here and elsewhere from people trying to do the same thing but none of the suggestions work . I wonder if this is due to a symfony-2.8 change that prevents these things from working I ve tried without success : .. . .. . overriding the sonata.core.form.type.equal service . This produces the error : .. . .. . The field type Sonata CoreBundle Form Type EqualType is not registered with the service container . trying to configure the mapping in config.yml as follows : .. . .. . Note : Ive tried to derive the config syntax from the DI classes so this might be inaccurate . the sonata.core docs dont seem to list any config instructions in this area .. . .. . following these https : sonata-project.org bundles core master doc reference form types.html instructions by using the FormHelper methods in the bundle class . this gets called but immediately gets overriden by the sonata DI classes . Ive even tried using composers classmap option to hook the custom class up directly but it didnt work . Im new to the Sonata project bundles so there may be a way of solving the original issue without having to go through these hoops . Comment : Sonata admin 2.3 has some issue with SF 2.8 . If you can t upgrade now to 3.0 try 2.3.9 instead of 2.3.10 . But I highly recommend to upgrade 2.x is not maintained anymore . Comment : many thanks for that . 2.3.10 cured it 2.3.11 appears to be the culprit .", "Question : I m trying to override the SonataUser Admin Model UserAdmin s configureFormFields because I need to remove some default fields from the admin form . So I have copied the file vendor bundles Sonata UserBundle Admin Model UserAdmin.php in my bundle app Application Sonata UserBundle Admin Model UserAdmin.php and modified it . Then declared it as a service : .. . .. . Now questions : Am I doing right How can I tell sonata-admin to use it .. . Answer : It is a better practice to keep your bundles in the src directory instead : See Creating a bundle section http : symfony.com doc current book page creation.html . In this case if you are using easy extends make sure to use --dest src in order to generate the bundle inside an Application namespace in src . By creating your overriding bundle in src Application Sonata UserBundle and registering the vendor bundle as a parent you won t have to create a new service . This explains you how to override the bundle properly : overriding a bundle http : symfony.com doc current cookbook bundles inheritance.html and should save you a lot of time . Don t forget to create the file you want to override in the same location as your parent bundle . In your case you would have to copy-paste SonataUser Admin Model UserAdmin.php from the vendor into your bundle src Application Sonata UserBundle Admin Model UserAdmin.php and modify it as you wish . That s why overriding bundles can be so useful . Comment : Actually I used SonataEasyExtends http : sonata-project.org bundles easy-extends master doc index.html to extend the SonataUser Bundle as told in the docs http : sonata-project.org bundles user 2-0 doc reference introduction.html it automatically creates the structure of the extending bundle . It s using app Application by default I left it because it s always mentioned like that in SonataUser docs . Comment : If you specify no parameter the files are generated in app Application Sonata.. . but you can specify the path with --dest src . I have updated my answer . Comment : I saw that I intentionally left it because they are still using this path in the docs . I ll move it later maybe . The question is more about the way to tell sonata to use my new Admin class . Comment : You can still override the class instead of creating a new service anyway . Good luck : - Comment : That s what I did see my question but this class don t get overridden .", "Question : I m trying to override the SonataUser Admin Model UserAdmin s configureFormFields because I need to remove some default fields from the admin form . So I have copied the file vendor bundles Sonata UserBundle Admin Model UserAdmin.php in my bundle app Application Sonata UserBundle Admin Model UserAdmin.php and modified it . Then declared it as a service : .. . .. . Now questions : Am I doing right How can I tell sonata-admin to use it .. . Answer : The overriding class should be set in config.yml : .. . .. . Extend original UserAdmin : .. . .. . Of course change class name MyCompany UserBundle Admin Model UserAdmin to reflect your bundle structure .", "Question : I ve hitting my head against the wall for countless hours now and I hope SO can be of help I have Retailer Branch and RetailerBranches entities which work just fine retailers can have many branches and a branch can only have one retailer . The hard part happens when trying to make Sonata Admin SonataAdminBundle play nice with that relationship . In their simplest form they look like this : .. . .. . Retailer entity .. . .. . RetailerBranches join table .. . .. . Branch entity .. . .. . The harder part happens when trying generate the form to allow that relationship to take shape : .. . .. . RetailerAdmin .. . .. . RetailerBranchesAdmin .. . .. . The problem : .. . .. . All this sort of works here s a screenshot : enter image description here http : i.stack.imgur.com YPX0L.png .. . .. . There s a Retailer and its Branches . Yay . Problem 1 : The Add new button at the bottom attempts to add a RetailerBranches object instead of a simple Branch object which obviously doesn t work . Problem 2 : This method also doesn t allow the user to modify a Branch inline . I feel like I m close to the solution but I just cannot quite get there . Any help would be greatly appreciated Comment : This Sonata again.. . I see so many people fighting it longer than it d take to write all that stuff yourself . Why do you need it at all If you need stuff like Sonata you probably want a CMS not a framework . Comment : That s what I m about to do . It s a neat piece of code but the documentation is so so poor . Comment : I have found another way to get this done will work on it tomorrow and post my findings . Comment : I m using Sonata Admin for half a year now and run into many not documented use cases . But it is in open-source project and a lot of people are doing an awesome job on improving and adding new features . That s why I took the uses cases talked to the contributors about there best practice and added them to docs . It s a simple GitHub fork and adding some lines . Feel free to join @Pier-Luc Gendreau and Elnur Abdurrakhimov . : .. . Answer : When needing to edit OneToOne or other relationships on the same page in Sonata Admin you could also create Admin classes for each Entity and add to config.yml and simply add the entire entity to your form in you main Admin class like so : .. . .. . see Sonata Doc http : sonata-project.org bundles admin master doc reference form types.html", "Question : I have installed Sonata Admin Bundle https : sonata-project.org bundles admin and User Bundle https : sonata-project.org bundles user in my Symfony 2.6 application .

I only need Username E-Mail Password Groups Firstname and Lastname for my admin user creation . How can I remove the other unnecessary fields from that page .. . Answer : Under configuration for sonata user bundle in config.yml i.e sonata user you can override sonata user admin class and define your own admin class .. . .. . Now create your user admin class in your extended bundle i.e ApplicationSonataUserBundle and extend your class with sonata s Sonata UserBundle Admin Model UserAdmin now in configureFormFields define your desired fields you want to add .. . .. . Or remove some of the fields : .. . .. . See ADVANCED CONFIGURATION https : sonata-project.org bundles user master doc reference advanced configuration.html for sonata user bundle" ] }

Answer : I don t think Siebel generates this part in it s WSDL the examples on Oracle and other blogs mention that the extra Headers need to be sent in the incoming SOAP to Siebel but they are not present in the generated WSDL .

Oracle will not provide support for changes customizations or extensions made to the Oracle Commerce Siebel Reference Integration Pack code or for any implementation issues that arise from such changes . Below is the config atg Initial.properties from the Oracle Commerce and Siebel Integration reference application for version 11.1.1 : .. . .. .

I have the Siebel open UI Add-in Enabled however still it is identifying as Web object . .. . Answer : Siebel Open UI is implemented as a WebExtensibility http : www.advancedqtp.com DemoMTW content tech.web ext.html project in UFT so most of the objects will still be recognised as plain web-objects . The two main differences that Siebel Open UI support adds are : .. . .. . 1 . New test objects are added the most common of which is SblOUIAdvancedEdit . 2 . Additional levels are added into the object repository in order to segment the application more correctly these objects are usually SblOUIApplet but SblOUITable will also contain the objects within it . So a typical script line could look something like : .. . .. . Regarding SblOUIAdvancedEdit this object is not identified for every edit field only those which have an opener element inside it which allows opening a dialog to set the edit field see picture below .

There are already bug enhancement requests raised for a way to modify these messages but so far there is no Oracle supplied solution .", "Question : i would like to know . Is there any way where i can interact with Siebel application using Selenium Java script . any add-on required Comment : Can you give us a clue about Siebel otherwise you may never get an answer If it involves web-applications then surely yes . .. . Answer : I have automated Classic Siebel application using QTP10 and it worked alright . However with Selenium WebDriver I was not able to automate because classic Siebel does not have a proper HTML code for Selenium WebDriver to access and control in the browser . After reading through the documents on Siebel Open UI I believe that proper HTML code will be visible in the browser . If the HTML code is available Selenium can automate the application A quick google-search returned the following result on the topic - http : www.tricentis.com enterprise-solutions solving-the-top-three-challenges-with-siebel-open-ui http : www.boxfusionconsulting.com boxfusion-blog siebel-open-ui-automated-testing .. . .. . If the HTML code is not available you can also look at providing javascript hooks from your Siebel aplication and then use Selenium to execute the Javascript code . The same principle is used in automating flash using Selenium . http : www.adobe.com devnet flash articles flash selenium.html https : code.google.com archive p flash-selenium . This is a long shot but worth a try", "Question : This might fall under the product support category so if it s off topic let me know . There doesn t seem to be anywhere in SE or elsewhere online to ask questions for help in Siebel and Open UI .. . .. . Anyways I m trying to do something simple and include a custom css file with Siebel Open UI . This is just for testing purposes so I can start twaeking the UI and see what can be done . Most guides such as this http : www1.askmesiebel.com 2014 02 how-to-change-theme-in-openui this http : www.siebelhub.com main 2013 01 siebel-open-ui-custom-themes.html and this https : docs.oracle.com cd E14004 01 books config open ui customizing mobile23.html mention editing the theme.js file located at PUBLIC language build SCRIPTS siebel . .. . .. . Problem is this file doesn t exist in my installation . The only theme.js file at all is located under PUBLIC language webeditor themes theme.js . The contents of this are minified and when I run it through a beautifier it has nothing of the siebelApp.ThemeManager.addTheme that the tutorials talk about . This instead starts with CKEDITOR.themes.add default function which is similar but I can t use it to follow the tutorials to add a theme and reference a css file . .. . .. . I ve tried every guide on this I can find through Google but it always comes down to editing theme.js file to have Siebel include a custom css file . I ve even tried creating my own theme.js file and putting it in scripts siebel custom and added that to the manifest but no luck . Is Siebel not installed correctly I have Siebel Tools Client and a sample db . Or am I missing something else .. . Answer : File theme.js was deprected starting from Siebel IP2014 . Now to add a new custom theme you have to do following : .. . .. . 1 . Create separate CSS file with your custom style .. . 2 . Put this file to PUBLIC language files custom folder .. . 3 . Add this file to Siebel manifest : .. . 1 . Navigate to Site Map Administration - Application Manifest Files .. . 2 . Create new record with a path to your file path should start from files custom .. . .. . 3 . Navigate to Site Map Administration - Application Manifest Expressions .. . 4 . Create new record with expression LookupName OUI THEME SELECTION Preference Behavior DefaultTheme YOUR CUSTOM THEME NAME .. . 5 . Navigate to Site Map Administration - Application Manifest Administration .. . 6 . Create new record in the UI Objects applet Type Application Usage Type Theme Name YOUR CUSTOM THEME NAME .. . 7 . Create new record in the Object Expression applet with the expression you ve created previosly . Level should be equal to 1 . 8 . Create new record s in the Files applet . If you just extend vanilla Aurora theme with your custom CSS rules than you need to add both files here and sequence is important - first one should be files theme-aurora.css and the second one is you custom CSS file . If you create CSS file from scratch or just copy aurora file than you just need to add only your CSS file . 4 . Create new record in LOVs Type OUI THEME SELECTION Display Value user friendly name of you theme LIC YOUR CUSTOM THEME NAME Parent LIC NAVIGATION TAB or NAVIGATION TREE or NAVIGATION SIDE Comment : Thanks . Is it just me then or is the documentation at http : docs.oracle.com cd E14004 01 books config open ui config open uiTOC.html http : docs.oracle.com cd E14004 01 books config open ui config open uiTOC.html a bit out of date then Comment : Documentation you pointed to is actualy for IP2013 version this can be determined by code E14004 in URL .

I could develop some tools myself but i don t want to reinvent the wheel . If someone have more informations interesting articles interesting way to do this it could be very usefull for me . Thanks .. . Answer : This is really several questions in one . TDD is a way of working but I think you are already wel versed in what this entails . It can be applied to any kind of technology . From that stance I feel comfortable saying that it s possible with Siebel as well . As for the tooling to be used it very much depends on the version of Siebel you are on HI Open UI the skills of your developers the way of working at your project Agile Waterfall the test automation tooling used and the general level of automation at the project program . To me it sounds more like a way-of-working transformation then the implementation of a test approach .", "Question : I have a requirement to create a business service function to calculate expiry date 2 weeks from a date field in Siebel .

Specifically I d like advice on the following areas : .. . .. . How should we set up version-control specifically with Subversion What kind of structure should our repository have How should we handle branches and tags How can we do code reviews How can we peer review configuration changes made through Siebel Tools that don t necessarily have any code We want to review these changes for quality assurance and knowledge transfer as well as compliance with change-management policies . What sort of change-management works well with Siebel How do we verify that only things listed in our change log are actually changed when we do a new deploy How can we automate testing of our application Is unit-testing even possible with Siebel I saw another question suggesting QTP for web testing but are there other options that work Are there other things we can do to implement Continuous Integration practices with our Siebel development efforts What recommendations do you have for naming-conventions and other things that would traditionally fall under coding-style guidelines How should we separate development roles from Siebel Administrator roles What should our build test deploy cycle look like It s not likely that I ll be able to obtain any new expensive tools for this but if there s a paid tool that provides really great ROI feel free to mention it . If you have other recommendations along these lines but not specifically addressed by one of my questions feel free to add that as well . .. . Answer : SVN CVS are not suitable for Siebel a few reasons being .. . a Siebel objects are db objects and SVN CVS etc store sif equivalent of the changes . These changes are impossible to query except for some basic queries . b The integration between Siebel tools and SVN is a loosely coupled integration . The ideal integration should be with the Siebel repository and invidual tools . Take a look at our tool Object Hive it addresses many of the short comings of a files based version-control . http : www.enterprisebeacon.com siebel version-control tool.html .. . Object Hive has been from the ground up specifically for Siebel version-control some of its features are : .. . 1 Object Based repository similar to Siebel repository that stores all version history . This makes is very easy to query changes and conduct code reviews based on the changes .. . 2 A browser based GUI that is similar to Siebel tools to query for version history no combing sif files for changes . 3 Seamless integration - directly integrates with the Siebel repository .

Answer : If you ensure that the Siebel Open UI Test Automation capability is enabled on the server three additional Siebel OUI specific properties are made available for UI objects in the HTML . Those properties are : .. . .. . rn - Repository Name - the unique name assigned to the UI object by your Siebel developers . un - UI Name - name or caption of object as it appears in the UI . ot - Object Type - type of object that the HTML element represents .

I need a floating window this should not be a pop-up window . With a popup window the data main window cannot be edited . The user should be able to edit data in main window as well as floating window without closing the floating window . And the data in main window and floating window are not from same BC . They are just linked . I tried ShowPopup method but that is giving me a popup . If someone knows how to design floating windows in Siebel application . Please help . .. . Answer : As far as I know that is not even possible in Siebel . At least not easily . The only thing you can add to a Siebel view are applets . Inside an applet you can embed advanced controls like an ActiveX object a Java applet an external web page.. . but they wouldn t have the appearance nor the behaviour of a floating window . Via server scripting you can open popups raise error texts and that s all . In browser scripts you have a few more options alert confirm etc but nothing useful for your requeriment . Maybe you could tweak the webtemplate files and insert your floating window HTML code there.. . and use browser scripts to show-hide control the window . But then you could have only HTML you wouldn t be able to add fields to it . Also it would be a total pain to make it work and a maintenance nightmare since the very first moment . If you were using Siebel 8.1+ you could try the new OpenUI instead of the standard ActiveX interface . It s based on CSS and jQuery so it should be easier to tweak the appearance . But it s only available for Siebel 8.1+ .

We use IE11 compatibility-mode enabled . The problem occurs after a popup is opened for the second time . Comment : Compatibility mode helps in IE10 mostly .

For this example we will be using the SLComposeViewController s SLServiceTypeFacebook . If you wish to use Twitter or SinaWeibo just change out the SLServiceType to one of the following : .. . .. . SLServiceTypeFacebook .. . SLServiceTypeSinaWeibo .. . SLServiceTypeTwitter .. . .. . iOS 6 has made it very easy to post directly to Facebook Twitter or Sina Weibo using the SLComposeViewController . This works very similarly to iOS 5 s TWTweetComposeViewController . First in your view controller s header file .h import the Social Framework and the Accounts Framework . import Social Social.h .. . .. . import Accounts Accounts.h .. . .. . Here we will declare a simple UIButton and an IBAction that we will later link-to that button and a void sharingStatus which will be used to check that the selected sharing service is available . Then in your implementation file .m we ll start by implementing the sharingStatus void that we declared in the header file . sharingStatus uses SLComposeViewController s isAvailableForServiceType BOOL to return whether or not you can post to the service specified in its arguement . In this case we will use the service type SLServiceTypeFacebook . If the service is available the post button will be enabled with an alpha value of 1.0f and if the service isn t available the button will be disabled the its alpha value set to 0.5f . Here we will set up the IBAction that will call up the composer . For good practice we will check isAvailableForServiceType again to avoid calling up the composer for a service type that isn t available . Incase something went wrong during the last check or if availblility somehow changed in the fraction of a second in between tapping the post button and the composers alloc init . The code below has been set up to display a Facebook composers sheet with text an image and a link . This action also utilizes a completion handler for the composer s canceled and done results . In viewWillAppear we will register an observer to ACAccountStoreDidChangeNotification so the application can be notified when account information changes . This observer will then be removed in viewDidDisappear . And finally open up interface-builder and add a UIButton which will be the post button . Then in the connections inspector link the IBOutlet and IBAction we created earlier to the button and that s it You re done enter image description here http : i.stack.imgur.com 2tR7g.png Comment : Hi It was a nice answer though i have small doubt can we also present Login interface in case user s twitter Facebook account is not set up Comment : @AbhinandanSahgal no not with this class . However when working properly the composer will detect if the user isn t logged in and present an alert to take them to the settings for the appropriate service to log in to their account . Comment : @AbhinandanSahgal Sorry but no I can t . This is build in behavior that should be working automatically if you aren t already logged in . Additionally Apple used to offer API for sending the user to the preferences app but it was removed in iOS 5.1 : Comment : There s no need to link-to Accounts.framework when using Social.framework . Also it can be a disadvantage to check if a service is available since the OS will do this automatically and fail with an alert that has a Settings button .

Answer : My website serves blank pages to social urls i.e . urls that start with social as a path and originally generated by my app to share on FB and Twitter . Those served pages only include open graph and twitter meta-tags in their head and a few lines of javascript to redirect the user to either a deep link-to the app iTunes or the appropriate section of the website when they visit the page . I m using this technique to avoid distracting my web server by serving unnecessary content sometimes significantly large amounts of content to social media Twitter Facebook whereas all they really need to represent data is just meta-tags . My shared social links are successfully tested on both Facebook and Twitter online validators . They re also presented as expected on both FB and Twitter timelines when shared from the app but the only problem I m having is SLComposeViewController twitter dialog which displays a blank image preview as a preview of my blank page I guess when the user is prompted to enter his tweet . Also neither the title nor the description from the url page meta-tags are pre-rendered in the tweet dialog which might give the impression of something wrong to the user and potentially canceling his tweet . If the user decides to post the miss-previewed tweet though everything goes well and the card displays on his timeline properly . I m experiencing the preview problem only with the Twitter dialog with Facebook the post preview is presented as expected to the user before he validates his post .

Comment : Did you check condition for twitter if SLComposeViewController isAvailableForServiceType : SLServiceTypeTwitter Comment : @Rushi Absolutely the parameter serviceType in my code above is equal to SLServiceTypeTwitter when I share on Twitter . I reiterate the dialog shares successfully on Twitter the card displays properly in the timeline when the user clicks the post button . The only problem is the preview before the post neither the title nor the description nor the image are pre-rendered in the tweet dialog which might give the impression of a bug to the user and potentially cause them to cancel the tweet .", "Question : Our app has sharing options with Twitter that was implemented with third party libraries and I m trying to re-implement them .

Comment : Do you see any error messages in the debug console If you replace the prettyPrint call with alert onload happened does it pop--up an alert when you expect .. . Answer : I believe your test page is using Blogger s Ajax templates not sure what the official name is whereas the other link you posted is using classic templates . If you reload your test page you ll first see the Blogger logo in the middle of the page then your content appears . If you view the test page source you ll see a lot of code but not your content . I believe with layout templates Blogger s code-first runs then it fetches your content using Ajax . Any JavaScript code that runs on document-ready DOMContentLoaded or window load will run before your content is loaded into the page . I believe if you add a HTML Javascript widget http : www.wikihow.com Add-a-Widget-to-Blogger to the page after your content block then include a call to prettyPrint within that widget it should be called every time a post is displayed . .. . .. . Update : The official name of this template is Dynamic Views and it appears that the HTML JavaScript widget isn t supported for Dynamic Views . I can t find any mention of an API that lets you hook into Blogger s JavaScript so I believe the answer for now at least is that it s not possible to add template-level code to do what you want . The most practical way would be to include a script-tag with prettyPrint in every post : - .. . .. . .. . .. . Update 2 : I ve traced through Blogger s code and I think I ve found a suitable and bindable event . Try including this after the Dynamic Views code in the head element after the script src www.blogblog.com dynamicviews .. . script tags : .. . .. . The viewitem event is triggered every time the user views an item which can happen multiple times in the page s lifetime . The element argument is a jQuery object of the item s container element so if you want to save prettyPrint a little time you can do this : Comment : Thanks . Is there any way to do this on the template For example is the anyway to hook into blogger s ajax success callback from the template itself Comment : HOLY COW THAT WAS AMAZING .

Answer : There can be a few problems with your snippets above . If you hook an event with body onload .. . other javascript codes could overwrite it . Dom.addEventListener will not work with internet-explorer you need to use Dom.attachEvent there . Basicly when I don t or can t use a javascript-framework like jquery for event-handling then I use my old code for onload event-handling : .. . .. . I attach two codes which work in slightly different ways . Mainly if you use document.ready 2nd snippet then the hooked code will run when the page is loaded and all HTML elements are created . But on document.ready there is no guarantee that all javasript and css codes are loaded also so if you want all codes and scripts to be loaded then you need window.ready 1st snippet .

Can you post what you are trying to insert into the code block Are you using lt gt or and Comment : I m using lt and gt but when I save the post its turns into and @adilapapaya Comment : one thing that s just odd to me is that it s not even syntax-highlighting the php or css code but rather just printing it our like a regular code block . I m wondering if there s an error in the way you re applying it . Maybe try removing the class lang-html from the code blocks and just using straight-up code code to see if it shows up Comment : Just got rid of it . But it still doesn t show @adilapapaya Comment : hmm ok one more thing you can try is to add html markup to a php code block . E.g . add a div something something div to one of the php code blocks at colourity.com posts arrays-in-php http : colourity.com posts arrays-in-php and see if it shows up . It does when I do it from the browser but not when you load it directly into the html so I think the script must be messing up somewhere . I m just not sure where ." ] }

Answer : The second location should make itself known via a touchesBegan event . In your UIView you need to have public methods for the OS to call and one of them is void touchesBegan : NSSet touches withEvent : UIEvent event . touchesMoved will only list existing touches .

Should I implement the method override func motionEnded motion : UIEventSubtype withEvent event : UIEvent in every panel then Or is there a way of implementing it once and populating it across the whole app .. . Answer : First of all lets find out where these motion methods come from as docs say : .. . .. . The UIResponder class defines an interface for objects that respond to and handle events .

Hope it helps Comment : Thank you it does help a lot Just two small questions - should I put this protocol in a completely new and separated file The same with extension - where exactly can I put it Comment : It is does not really matter but it is a good way to separate files to logic pieces so I would advise to implement protocol and vc extension in new file .", "Question : null .. . Answer : I m trying to mirror a view controller : .. . .. . 1 . app instantiates view controller 1 of class A .. . 2 . app instantiates view controller 2 also of class A on another UIWindow external display via Airplay or physical connector .. . 3 . any touch-event that view controller 1 receives should be mimicked on view controller 2 .. . .. . I ve got part of this working on things like MkMapViews and simple view controllers by just catching things like region changes or scrolling in vc1 and telling vc2 to set its region or scroll to that position having UIControl IBActions on vc1 also call the same action in vc2 etc . This works with simple cases but the problem comes with complex view controllers that have things like UITableViews with custom UITableViewCells that expand contract etc . I find myself having to implement every single possible delegate action and make a bunch of objects aware of things they shouldn t be aware of which just seems wrong if I m going to make this at all reusable . I ve tried walking the subview tree of vc1 and using objc setAssociatedObject to associate the UIResponders in the view controller instances with each other but I still have to catch every delegate action on vc1 to look up the UIResponder on vc2 to mimic the event . There has to be a simpler way to do this . I tried subclassing UIWindow and overriding sendEvent and sending the event to the external display s UIWindow as well but each UIEvent seems to have info in it that ties it to the UIWindow it originated in as the external display UIWindow did nothing with it when I sent it . How would I do this in a way that would allow me to abstract away the mirroring into a nice subclass or something so I don t have to litter every view controller with special-case code I ve thought about swizzling UIView s touch-events but I m not even sure if that will help since UITouches and UIEvents are tied to the UIWindow they originated from and UIEvent doesn t seem to provide a way for me to create my own event . NOTE : what I m trying to do is not default Airplay mirroring as I want the external display experience to take advantage of the full display resolution and dimensions . The idea is to allow an iPhone app to work on the device itself i.e . taller than it is wide while also providing an experience on an external display that is geared for that display wider than it is tall greater resolution opportunities to present info in a more readable HDTV-friendly format . Thoughts Comment : Any luck with this challenge Comment : Not really . It was a demo project and I ended up doing what I feared - that being implementing every single delegate I could checking to see if the VC had a mirror VC and if so calling the same delegate on the mirror VC . It was ugly and demanded that every VC was aware of it s mirror and while it worked for a lot of UI actions it didn t work for everything . I d really love to know how to do it better .", "Question : On Mac one can always get the location of the mouse outside the event stream ie even if you ve not subscribed to any delegate methods for mouseUp : et al by calling NSEvent mouseLocation .

Not getting touch-events is not because the app is unduly burdened with heavy processing it s because touches which are in progress when the app opens are not delivered to the app via the normal means .

Comment : I think that this is not possible . UIApplication is not suitable for subclassing and that is the entry-point for your application Comment : Understood .

If there were a method which were being called on UIApplication for touches already in progress at launch I would go that route . Do you know of one .. . Answer : This cannot be done . The simple reason : The touch-events don t belong to your app . Each touch belongs-to some UI element or responder . As you already know this element gets the began moved ended cancelled messages . This is even true within a properly programmed app : All events regarding one touch are delivered to the very same object . After all how would another object know what to do with that event and how should the first object properly finish its expected behavior While you can or could but probably shouldn t find a work around within your app there s just no way for cross-app-touch passings . And on the Mac you may query the mouse position but in normal application flow there ll always be a mouse down before you get a mouse up event . To be honest I don t see any reason why this would be needed anyway.. . oh wait.. . I could split my app icon into several areas.. . not sure if it would already break privacy laws though if you get to know where the user has his icon on screen .

I need to monitor all the current touches but touchesBegan touchesEnded touchesMoved and touchesCancelled all only give me the touches that they are monitoring .

If there were a method which were being called on UIApplication for touches already in progress at launch I would go that route . Do you know of one .. . Answer : I think you could simply extend the application launch . When I had time consuming tasks during my application launch I used to show the same splash-screen with a UIActivityIndicator while the action was being carried out . You could simply create a NSTimer wait for about 2 seconds and during this time check for touches while the splash-screen will still be showing . To do this in applicationDidFinishLaunch push a ViewController that looks exactaly like the splash-screen and check for touches in this ViewController . After those 2 seconds proceed with normal initialisation . This behaviour also helps if you have time consuming tasks during initialisation . I know it s a workaround but my guess is that it is not possible to check for touches because application will be working on the main thread and the touches also processes on the main thread . This could happen also because there are no ViewControllers or UIWindow initialised and ready to listen to touches .

Views A blue and B red are both subviews of the same superview gray . In other words they are both siblings and the order decides on which of them covers the other . Option 1 : View B red has a regular UIButton as its subview . Option 2 : View A blue has a regular UIButton as its subview . Given Option 1 for the sake of explanations : View A blue has a UITapGestureRecognizer or maybe even more other UIGestureRecognizers attached . What would be the most elegant approach to make sure that the UIButton does receive all touches on its region but also the view A blue receives those touches on its UITapGestureRecognizer If possible by any means the solution should not involve extending the UIButton -class and manually forwarding any events from the button itself . Imagine view B would contain a lot more controls and not just a button . All of those controls should somehow allow view A to receive the touches on its UIGestureRecognizer . I did provide two options as I do not care which of those views A or B comes first as long as both receive the touches . All of my approaches so far abruptly reached dead-ends . Maybe a custom responder-chain would be a nice solution I keep thinking that there must be an elegant solution within the entire UIKit UIEvent UIResponder stack . Comment : +1 for such a thoroughly crafted question : .. . Answer : Have you tried with this http : developer.apple.com library ios documentation uikit reference UIGestureRecognizer Class Reference Reference.html cancelsTouchesInView A Boolean value affecting whether touches are delivered to a view when a gesture is recognized . Comment : I did try that with both Option 1 and 2 and using that property did not make any difference in both cases only the button or only the view received the touches on that button-region . Comment : Whoops I did actually try a different option when attempting to get cancelsTouchesInView to work . My button was a sibling of view A and B hence the property had no effect . When using option 1 as described in my question that property works exactly as described . Any touch onto that button triggers the button touch-up-inside as well as a touch gesture-recognition on the superview of that button . That does not actually solve my entire quest get touch recognized also onto that other view but it gets me a big step closer to the goal - hence a +1 - ty .

Answer : I am working on a project where I want to manually run the main event-loop on IOS . That is to say I want to dequeue the UIEvents myself from the source and then send them on to the UIApplication . I have found examples on how to do this for OS X and it works . In that case it is a matter of calling nextEventMatchingMask and then sendEvent on the NSApplication object .

I thought a solution was to post a UIEventSubtypeRemoteControlNextTrack notification but i can t found how to build a UIEvent notification . Has anyone already solved something like that Thanks .. . Answer : You can not stop Spotify app or any other app from playing using your app . Spotify has it s own process which is separated from your process . The notification you are trying to send will be sent within your app the system uses this notification to send to all processes apps registered for this notification when the user interacts with the remote .

It doesn t slides vertically . Which exactly do you want You can do this with a table view but actually I would do it in a UICollectionView they probably do that for the App Store . You can add the images slider as a supplementary view in a fixed position at the top of the collection view . This makes it easy to change layouts in the future and gives more flexibility around the behaviour of the supplementary view images slider .

Otherwise you have to build some kind of api between the client + v8 prerendering engine and the server to get the data which is what reactive-record does . You can look at reactive-ruby and reactive-record s code in the files labeled isomorphic.. . See the React.rb Reactive-Ruby branch readme for more info .", "Question : null .. . Answer : So I m basically still pretty new to the whole npm react.js let alone react.rb ecosystem and I m wondering if it would be possible to use reactrb with the gatsby static site generator .

Specifically where I got stuck was trying to get it to play nice with bundler . Is combining reactrb components with gatsby something that s even feasible I m hoping the answer is yes . Comment : Not sure actually.. . haven t seen reactrb before . What you ll need to find out is if you can include reactrb components in a JS project . From what I ve seen poking around all the documentation assume you re writing everything in Opal .

React.rb is NOT being loaded twice I have made sure a couple of ways including putting a console.log into the first line of the react source file . SOOO It would seem I need a way to completely clear reacts state between tests . Any way to do that .. . Answer : The problem seems to occur if you do a static render of a component that is later asynchronously updated i.e . when a promise is fulfilled . Once this happens react is busted .

Answer : It sounds like you re looking for a way to pass data to the client in the initial request . If you load the data in the server app and just want to pass it along you can look into the gon gem . TL DR version .. . .. . Here s enough to get your feet wet .. . .. . The explanation : .. . .. . The gon gem sets up a hash that will be JS-objectified and placed into your JS runtime in the browser . For more info on that see the Railscast http : railscasts.com episodes 324-passing-data-to-javascript about it it s still mostly relevant not much has changed . In the browser that JS object is also named gon so gon.current user would be whatever you set in gon.push current user : some user in the controller action or before action callback . But we ll need to convert that from a JS object to a Ruby hash using Hash.new gon.current user then you can pass that resulting hash to a User.new call . The important part : you ll need to have a User class in your Opal app . If your Rails app sets up User an ActiveRecord model you won t be able to reuse it so you ll need to create a new one but if it s just a PORO plain-old Ruby object you can add the following line to an initializer : .. . .. .

Thanks . Comment : Add react component to your partials Comment : @HieuPham I meant as I add partials edited the question sorry about that . .. . Answer : You would use react component in-place of a partial . So react component Components : : Foo name : @user.name rank : @user.rank .. . .. . would mount the Components : : Foo component at this point passing the users name and rank . There is no direct equivalent to content for when bridging between layouts and react . Instead you would break the view into several component one for each content for block and individually reference them using react component . Be aware that you can also directly mount the component from the controller using the render component method in the controller .", "Question : I have a form that makes an ajax request the problem is that every time I click on it the amount of times it makes that request multiplies . Now I m sure it s because of the way I ve set up submit-intercept but I don t know how else to do it whilst still encapsulating it as a single component . I m using react as my view layer and I ve attached a function that contains code to intercept the request and this function is called in both the afterMount callback and the after update callback if I don t do this then either the form-submit is never intercepted or it only intercepts it once and then just does a normal submit . Now obviously it s multiplying because those events fire and add an extra submit-handler . I m using opal and react.rb so the code might look a little odd . Here s my function that intercepts the submit action on the form .. . .. . Here are my call backs : .. . .. . I was able to reduce the amount of requests made by checking if the component state was already in the middle of a request whilst this doesn t reduce the amount of submit handlers being added it does stop a good amount from doing anything but it doesn t stop the actual multiplying of handlers being added . .. . Answer : I don t know why I didn t think of it till a colleague mentioned it but by moving the form to a sub-component I can now run the intercept code on the form components mount which only happens when it s rendered so problem solved", "Question : Is it possible to have NPM Webpack package Opal and Reactrb I would simply like to install Reactrb like this : .. . .. .

The Nodes are in the form of Tree Structure . Memory : It Occupies more memory DOM is only preffered in the case of small XML documents . Slower at runtime . Stored as an objects . Programmatically easy to implement . Ease of navigation and use . SAX : .. . .. . Sequence of events . It doesn t use any memory preferred for large documents . Faster at runtime because of the above mentioned point . Objects are to be created . Need to write code for creating objects . In SAX Backward navigation is not possible as it sequentially processes the document . Comment : +1 . This is an excellent comparison . I would emphasize that SAX is more difficult to implement because you the programmer must step through the nodes .

RESOURCE NAME equals META-INF services org.xmlpull.v1.XmlPullParserFactory .. . .. . I must admit that i didn t find a way to bind in the needed META-INF directory into the executable which would have been one of the most elegant solutions . But since the XmlPullParserFactory.java http : m-im.googlecode.com svn-history r79 trunk m-im src org xmlpull v1 XmlPullParserFactory.java file and XStream library is open-source you just need do add one line of code into above s source file and replace the old class with the new one - and that s it . In the public static XmlPullParserFactory newInstance String classNames Class context function the program only wants to read from the RESOURCE NAME file when classNames null . So what we do to avoid this is to assign the RESOURCE NAME s file content to the classNames variable by our selves and for that place this line of code above the if classNames null classNames.length 0 DEFAULT .equals classNames statement : .. . .. . org.xmlpull.mxp1.MXParser org.xmlpull.mxp1 serializer.MXSerializer is my RESOURCE NAME-file s content .

Answer : I think that you ve made a couple of mistakes in your implementation platform choices : .. . .. . You probably didn t need to go to the lengths of implementing stuff in native-code for speed . For most things you can get roughly comparable speed in Jana as in native-code especially if you take the time to profile and optimize your Java code . Assuming that you did CNI was a poor choice . You would have been better off using JNI or JNA both of which allow you to use Oracle HotSpot OpenJDK releases . GCJ is a poor choice because as you have observed some things don t work and debugging is more difficult . See also Is GNU s Java Compiler GCJ dead http : stackoverflow.com questions 4035538 is-gnus-java-compiler-gcj-dead .. . .. . Relying on a library that you cannot get source code for is unfortunate . My advice would be to revisit as many of those missteps as possible . Comment : Thank s for your reply @Stephen C The client has to work on very time-critical tasks even a very small increase of its speed has a big effect . But rewriting the whole project to C C++ or in some parts even to Assembler would be too much work for a minimal increase of speed . So using JNI was my first idea . Then i got aware of CNI and read that it is more efficient . I did several speed tests and CNI tourned out to be the best choice for the algorithms i want to use . Since CNI is in maintenance mode i thought there should be a way to get it work . But if it turns out there isn t i ll use JNI . Comment : Yes .. . well I still think you have made bad choices and that you are paying the price . If I was your PM I d have asked for some hard numbers to back up your assumptions that the tasks were really time critical and that a pure Java solution really wouldn t work . This has the smell of premature-optimization . I can t offer you any help to get your current approach to work .", "Question : i am parsing xml from a website .

Answer : This is how i got the login to work . the trick is not to put the wsdl on the url", "Question : I have been asked to write a utility to search a large number of XML files for elements with a missing attribute . The department responsible cannot just make the attribute mandatory in the DTD because it will break hundreds of files . They want to edit them manually over a period of days weeks . I am writing a small command-line tool in Scala 2.8.1 . I will be using a pull parser so that I can keep my code functional-programming pure and run it multi-threaded . I need the location of XML events . The API provided in Java 6 javax.xml.stream . XMLStreamReader has a method getLocation that returns the line number of an event . I can use this to write messages that inform the user where to look for the missing attribute . I would prefer to use the pull parser in scala.xml.pull.XMLEventReader but it does not appear to offer location information . Am I missing something Is it somewhere else in the Scala API Comment : possible duplicate of How to track the source line of an XML element http : stackoverflow.com questions 4446137 how-to-track-the-source-line-of-an-xml-element Comment : I m amazed at how low the original duplicate of this question is on the list of related links . I ll try editing its title to make it closer . Comment : Ugh . I failed to see that what I thought was a the original question was a full XML loader while this is concerned about pull reader . Sorry . I d retract my vote to close if it was possible . Comment : It is not a duplicate . The other question deals specifically with SAX parsers -- the API for Locator is clear . I am trying to use the Scala StAX parser . I even know how to do it in the javax.xml.stream package just not the scala.xml.pull version . .. . Answer : As far as I can see this is not provided by the XMLEventReader api . It relies on io.Source and could provide access to the location but does not . I don t see an easy way to go around that as the object that has access to the position is private . You may want to make your own copy of XMLEventReader http : lampsvn.epfl.ch trac scala browser scala tags R 2 8 1 final src library scala-xml pull XMLEventReader.scala that produces a custom XMLEvent with the position . The method to modify would be override def elemStart which has access to the position and could generate another EvPos line : Int column : Int after each EvElemStart .

I noticed you are running tests on multiple devices you should take a look at dtmilano.blogspot.ca 2015 05 android-culebra-multi-device.html http : dtmilano.blogspot.ca 2015 05 android-culebra-multi-device.html", "Question : I am trying to build a program with Eclipse that will send touch-events via MonkeyRunner to an Android phone .

I searched for questions similar to mine and found that there were several .jar dependencies and I added them to Libraries under the Java Build Path but it still fails cannot be resolved to do .. . .. . What else am I missing besides adding the .jars to the libraries .. . Answer : If your intention is to send events from Java to a device you should use UIAutomator http : developer.android.com tools testing-support-library index.html UIAutomator from the Testing Support Library . UIAutomator provides a set of APIs to build tests that allow you to send events and interact with the applications on the device . Building with Eclipse may be difficult but not impossible or you can use Android Studio and make your life easier . However if you just want to send events to the device and want to use a scripting-language like python instead of Java you can use AndroidViewClient culebra https : github.com dtmilano AndroidViewClient which facilitates the creation of tests and scripts from a UI see Culebra UI https : github.com dtmilano AndroidViewClient wiki Culebra-GUI .

In addition to what mmutz said above I needed to do a few other things . I had to create a subclass of QSpinBox and implement focusInEvent QFocusEvent and focusOutEvent QFocusEvent . Basically on a focusInEvent I change the Focus Policy to Qt : : WheelFocus and on the focusOutEvent I change it back to Qt : : StrongFocus .

Note that if you don t want to create a new QSpinBox subclass you could also use event filters instead to solve this . Comment : This way works for me instead of the accepted answer .

So I expect login page but instead it bypasses that and shows the redirect url . If I try separately without connecting to facebook for checking permission it works fine .

My applet has been online for several years with no reported errors . When I downgrade to version 6 Update 21 everything works perfect . My applet is not signed . SOLUTION : It took me ha while to find the cause of the problem . Actually in my case there were several factors causing the security error . The problem was solved by the crossdomain.xml file . The Java applet tried to download the crossdomain file failed and did not even bother to display an error in the java console debug level 5 . Java tried to download the file from the ip adress of my domain http : ip-address crossdomain.xml and not the root of my website http : domain-name crossdomain.xml . I guess it is better for the security aspect I then had to configure the webserver to expose the crossdomainfile on the IP address . In my case I have removed the default website in ISS for security reasons and had to create a new website . I then discovered that the java applet did not work with the crossdomain files i use with flash : .. . .. . I had to remove the site-control and allow-http-request-headers-from nodes from the xml file in order to make the applet work .

Answer : If you set separate jvm to true this has very bad effect on performance since new Java VM is instantiated for every applet . If you have multiple applets on the page 30+ this is pretty slow . I wonder if there is any other solution for this issue . E.g . we have multiple applets across multiple tabs . When the first tab with applets is opened all applets are shown correctly with no problems . But switch to any other tab results with the error for no registered plugin .

The problem is that Java applet code called from JavaScript has only permissions that are the intersection of the JavaScript s code and your applet code - and somehow the JavaScript s permissions are seen as less which results in this Exception . Here is what I did : assume you have a function innocentFunc that throws the java.net.SocketPermission exception so your code is something like so : .. . .. . Now what you can do is to change it to something like so : .. . .. . This AccessController call basically states to the Java Virtual Machine that the code it runs should not obey to the permissions from the call chain but rather only the caller s permissions in its own . Of course you should do something like this only after making sure that this innocentFunc call can t do anything bad even if invoked by malicious code .

Thanks", "Question : Firstly thanks for your time . I have a serious concern about Live Connect s OAuth2 API . I follows this and using DotNetOpenAuth to implement integrate LiveId authentication authorization for our federated-identity access management system . http : msdn.microsoft.com en-us library live hh243647.aspx authcodegrant .. . .. . Everything is working fine for quite a long time . But now I m having a serious trouble when fixing the replay attack issue for LiveId login module . Let s take a look at the Authorization code grant flow from the above article . 4 . The user-agent calls the client with the redirection URI which includes an authorization code and any local state that was provided by the client . For example : ...Callback.htm code AUTHORIZATION CODE . 5 . The client requests an access token from the authorization server s token endpoint by using its client credentials for authentication and includes the authorization code that was received in the previous step . The client includes the redirection URI that was used to obtain the authorization code for verification . .. . .. . Right after the step 4 Live Connect OAuth2 server returns to my callback endpoint with the authorization code state like the following : .. . .. . https : ssss.myapp.com : 443 liveid consume.idp code 406dd558-0cda-50cc-bd37-d964ec29fbb3 state uvygsnd3gba0jwi315kdyccs https : ssss.myapp.com : 443 liveid consume.idp code 406dd558-0cda-50cc-bd37-d964ec29fbb3 state uvygsnd3gba0jwi315kdyccs .. . .. . Problem is that authorization code could be used more than once . So it leads to the serious replay attack issue like the following scenario : .. . .. . 1 . User A when logging in to my application chose LiveId to sign-in then he s redirected to LiveId login page . He then logged in Live Connect OAuth2 server returned to the callback endpoint with the code xxx state yyy...user A then used this authorization code to obtain the access token.. . .. . .. . 2 . User B when logging in to my application chose LiveId to sign-in he then logged in at LiveId s login page . Live Connect OAuth2 server now return with code kkk state ggg .. . .. . If I this time use some tools like Webscarab to capture the response request then change the return from OAuth2 server to code xxx state ggg the old authorization code was given to user A not B . Then after that requesting for access token using this replay authorization code was going through smoothly . And guess what I received again the ACCESS TOKEN which was given to user A before...and finally user B can logging into my application as user A . Please be noticed that applying the same replay attacking like above for Google OAuth2 server I received bad request error from the server Google OAuth2 authorization code never could be used more than once . And the code flow or exactly the implementation for Google login LiveId login are exactly the same . I used DotNetOpenAuth.OAuth2.WebServerClient to implement the OAuth2 authenticating flow for both of Google LiveId . Again exactly the same code but Google OAuth2 server returned bad request when authorization code is reused but LiveId returned the old access token of the previous user . This is a serious security problem . Hope you guys have some ideas on this . Or hopefully I m wrong on some points . Please point it out . Thanks very much in advance Phuc Le . .. . Answer : The OAuth 2 spec is quite clear here https : tools.ietf.org html rfc6749 section-4.1.2 : .. . .. . If an authorization code is used more than once the authorization server MUST deny the request and SHOULD revoke when possible all tokens previously issued based on that authorization code . This is for the exact reasons https : tools.ietf.org html rfc6819 section-5.1.5.4 you mentioned above . In your case you should notify your provider http : technet.microsoft.com en-us security ff852094.aspx of this issue . Meanwhile you could implement a cache of used authorization codes on client-side and check for already issued codes . Note thate this could also produce false positives in the occasion that the provider randomly generated the same code for two different users which might be quite unlikely depending on the implementation . Comment : Thanks Gerlinger for the response Comment : Back to the issue . As specified in your link @ tools.ietf.org html rfc6819 section-5.1.5.4 https : tools.ietf.org html rfc6819 section-5.1.5.4 5.1.5.4 . Limit Number of Usages or One-Time Usage The authorization server may restrict the number of requests OR operations that can be performed with a certain token . This mechanism can be used to mitigate the following threats.. . As specified above I think the Live Connect OAuth 2.0 server chose the approach to limit the number of usage NOT one time usage . I will try to ask again in Live Connect forum to see if it s . Comment : About your solution that using cache to store the already-used authorization code for checking later . IMO that does not work for my case actually . Imagine that we have the application running on many servers which doesn t share anything to each other no central session or cache database....nothing shared . So maybe an authorization code is already used once in this instance server but not in others . Now hacker uses it for replay attacking another server instance there s actually no way to check . Please share you ideas Thanks a lot . Comment : @PhucLe As is specified in the spec it is not allowed to use authorization codes more than once . The sentence in the Threat Model spec aims for other tokens that could be prone to replay attacks . I just posted it to prove that limiting the usage or using one-time tokens is the recommended way to deal with replay attacks . In your scenario there s not much you can do about it than waiting for your provider to fix this issue or holding a common store for your servers . Comment : @Gerlinger : thanks that s what I thought too . It seems this need to be fixed by Live Connect OAuth 2.0 server team .

How do I get Jackson XML to JSON converter to output all child records in JSON Code .. . .. . Source XML .. . .. . Actual Output .. . .. . Expected Output .. . .. . Any help shall be appreciated . Thanks .. . Answer : The problem is that XML does not have distinction between concepts of Objects in JSON term that is collection of key-value pairs and Arrays ordered sequence of values without name . When using data-binding POJOs it is possible to determine from Java type which one a particular XML element means -- if Java property is a List or array it has to be Array otherwise Object -- but when only telling mapper to map XML to java.util.Map there is no such distinction and default handling will essentially consider all XML Elements to indicate Objects . And since Objects can not have properties with duplicate names only one of the values last one is retained . There is no simple way to avoid that using XmlMapper : you will need custom handling of some sort . Comment : I understand the reason for this issue but can you share some ideas on how to do this custom handling Do you know about any other Java library for XML to JSON conversion that can address this issue Comment : @Aman no I do not think it is possible to reliably convert from XML to JSON without having actual understanding of structure -- XML and JSON have different data models so you need to help with conversion . So better way in my opinion is to define actual Java classes to map XML content to and then serialize instances as JSON . This allows proper handling of list array values .

It only talks about Streaming Traversing and Binding of JSON data and nothing about sanitizing or similar functionality . Could someone please confirm . I need a library that can check the JSON data for any malicious or vulnerable content code . .. . Answer : What does such sanitization mean Page you linked to does not actually explain what it is supposed to do . But I am guessing it would be used to verify that input is valid JSON and not something that just resembles JSON such as Javascript code .

Answer : Make sure that you place the @JsonIgnoreProperties ignoreUnknown true annotation to the parent POJO class which you want to populate as a result-of parsing the JSON response and not the class where the conversion from JSON to Java Object is taking place .

Thank you Comment : Any particular reason for this behavior", "Question : I d like to use Jackson to deserialize JSON strings from client requests to Java objects and use FlexJson to serialize Java objects to response .

But this way Jackson also converts to JSON the response already converted by FlexJSON that I don t want . Is there any solution Thanks . .. . Answer : You should be able to build a custom MappingJackson2HttpMessageConverter bean where you plug in Jackson for the serialization methods and FlexJSON for the deserialization methods . Comment : Yes that could work however I have already found the better way . Spring has a number of default HttpRequestConverter instances pre-enabled and uses convenient one depending on the request Content-Type . So in my case it was just enough to add Jackson dependency in the project and send request with application json content-type . That causes Jackson to read data from the request body and deserialize to object . And response is not processed by Jackson . Comment : same here just added the jackson2 jars and you get to do things like at RequestBody YourDomainObject yourDomainObject and jackson does its thing . I imagine if you tried to return yourDomainObject the reverse would kick into effect with at ResponseBody but if you re using flexjson then you re most likely returning a ResponseEntity String which doesnt seem to trigger any jackson processing", "Question : I m using Jackson JSON library to convert some JSON objects to POJO classes on an android application .

Aalto is by far fastest of the three especially for parsing . It is commonly 50 - 100 faster than either Woodstox or SJSXP . One downside is that it does not handle DTDs and thereby not external entities it handles pre-defined and character entities . it seems that Aalto is the recommended way to read-write xml with jackson . However on jackson-dataformat-xml https : github.com FasterXML jackson-dataformat-xml maven-dependency page it recommends using Woodstox which has not been updated for some time . So what is the best way forward Woodstox or Aalto Comment : One small note on Woodstox releases : part of reason for few releases is that it is very mature complete and bug-free . If it ain t broke don t fix it . But there has been a new release 4.3.0 to add one feature that was missing ability to limit expansion of parsed entities needed to protect against certain forms of denial-of-service attacks using XML parsed entities .. . Answer : I think that Woodstox is the safest choice for correct operation given its wide functionality and being de facto Stax standard implementation -- most Java XML Soap frameworks use Woodstox . So if you just want least hassle all around it is a good choice . But Aalto is significantly faster and its features set is perfectly fine for Jackson XML module : DTD processing is not needed for JAXB-style data-binding . So I would say that this comes back to how much you value performance Aalto and how much simple no-hassle it just works with no problems whatsoever Woodstox . That is how I would choose myself if I was developing system myself . Besides switching from one to the other is trivially easy : so one possibility is to try Aalto and only if you face an issue FWIW there are no reported issue with Aalto Jackson as per issue tracker -- these are hypothetical issues .", "Question : null .. .

Answer : Jackson is complaining because it can t find a field in your class Wrapper that s called wrapper . It s doing this because your JSON object has a property called wrapper . I think the fix is to rename your Wrapper class s field to wrapper instead of students . Comment : Thanks Jim . I tried that and it did not fix the problem . I am wondering if I am missing some annotation. . Comment : Hmm what happens when you create the equivalent data in Java and then use Jackson to write it out in JSON . Any difference between that JSON and the JSON above should be a clue to what s going wrong . Comment : This answer worked for me with the example from the question .", "Question : I want to serialize a Map with Jackson . The Date should be serialized as a timestamp like all my other dates . The following code renders the keys in the form Tue Mar 11 00 : 00 : 00 CET 1952 which is Date.toString instead of the timestamp . I assume this is because of type-erasure and jackson doesn t know at runtime that the key is a Date . But I didn t find a way to pass a TypeReference to any writeValue method . Is there a simple way to achieve my desired behaviour or are all keys always rendered as Strings by jackson Thanks for any hint . Comment : JSON maps are just JSON objects with element name value pairs . A JSON element name must be a string . So Jackson is generating a string from what it was provided . .. . Answer : Since Jackson 2.0 maybe 1.9 too WRITE DATE KEYS AS TIMESTAMPS can be used to change this particular behavior . Usage example for ObjectMapper : .. . .. . and for ObjectWriter :", "Question : I am using Jackson library . I have number of java objects which are nothing but the wrapper for jsonNode . So want to convert these list of jsonNodes into single jsonNode . how can i do that . i tried this .. . .. . this is not working . ithere any other way .. . Answer : If each of your objects can be serialized then you should also be able to serialize a list of them to combine them into a json list : .. . .. . You can also ask Jackson to simply convert the objList to an ArrayNode instead : .. . .. . But if you actually had a method in Base to allow conversion to a JsonNode you could simply build ArrayNode yourself : .. . .. . This would avoid round-tripping via a JSON representation .", "Question : I have created a simple test case that shows the error . Please let me know if I ve missed something . I have a simple interface that declares a single accessor : .. . .. . When I run this unit test Jackson fails on parsing the json string : .. . .. . As you can see from the stacktrace Jackson correctly extracts the contextMap token from the json but it fails to continue tokenizing the string . As far as I know the json string correctly represents a map . Thanks Robin . Comment : What concrete class should Jackson use to unmarshall the JSON to the EventWithMap interface Moreover a Map containing foo as a key and bar as a value is normally represented in JSON as foo : bar Comment : I am using the MrBeanModule mapper.registerModule new MrBeanModule which is responsible for materializing POJO beans from interfaces . And a map is an array of objects in json i.e . . This JSON string was also created by Jackson so I expect it s valid and should be parseable by Jackson . Comment : That must be another side effect of this module because this code https : gist.github.com jnizet 9c7c991d0f92f6362ce7 produces json contextMap : processedAt : Thu Dec 31 14 : 30 : 51 EST 2015 . Maybe you should post a complete example containing the marshalling code as well that produces the JSON . Comment : Very interesting indeed . So there s no array token in the ObjectMapper serializer in your case . Mine was actually not created with MrBeanModule as far as I know it was created with log4j2 which uses Jackson for its JSONLayout appender . I will investigate whether this is a bug in that implementation . Thanks . Comment : According to the log4j2-dev group this representation was done purposely to make writing XML and JSON consistent : mail-archives.apache.org mod mbox logging-log4j-dev 201601.mbox http : mail-archives.apache.org mod mbox logging-log4j-dev 201601.mbox 3CCAOC1H uwW9SfoD5CKpqOqEvYNw 2B 3DFtPNbdWWA8Qqtv567VpFxw 40mail.gmail.com 3E .. . Answer : As others pointed out the problem is that JSON in question is structurally incompatible with the POJO : there is that unnecessary extra Array wrapper . But there is a way to handle this particular case : if you enable DeserializationFeature.UNWRAP SINGLE VALUE ARRAYS you should be able to get conversion for the specific case where array has one AND EXACTLY ONE value in it .", "Question : null .. . Answer : I m trying to serialize maps with arbitrary key types best effort using jackson and jackson-module-scala . I did plenty of searching of course I ve found cases for custom key deserializers but they won t do here - and I m also trying to avoid writing a custom map de serializer if possible . My basic idea is to serialize map as an array of entries entries being pairs length 2 arrays of objects - I know this is not quite map semantics but I think this is the closest I can get without converting keys to strings and then parsing them back to objects on a per-type basis . When learning about jackson s converters I was delighted thinking I could get away with writing just a pair of them - since jackson-module-scala happily de serializes both Seqs and Tuples I thought it could be this simple : .. . .. . All that was left is applying this as a global setting I did that via a mixin side question : is there a better way for this The serialization side works nicely the json output is exactly as described above however on deserialization results in a weird phenomenon : it does not fail but the insides of the map are of the wrong type . So serializing a Map MyType1 MyType2 works ok but then deserializing the result I get something that s more like a Map String Any the value being a simple type or another map for the entries . I suspect there is some type information lost in the process so I also tried to specializing all the type paramteres in the code replacing every with MyType1 MyType2 in the above effectively and interestingly it seemed to work ok obviously this solution is not generic .. . .. . So my question is : is there a way to make this work or any other way to achieve the same I feel like it s reasonable close but I can t seem to figure it out" ] }

Depending on your desktop system gnome kde there might be helpsystems but they are usually based on loose files and use full-blown browsers . usually webkit based .. . .. . For Lazarus http : lazarus.freepascal.org a CHM based helpsystem and embedded-browser was created including CHM write support . The reasons to avoid loose static html were mostly : .. . .. . 1 . the 60000 lemma static documentation took too long to install on lighter systems or systems with specialist filesystems . 2 . CHM removes slack and adds compression . 3 . we also support non posix and OS X systems and little filesystem related problems charsets encoding separators path depth etc and case insenstive filesystems on nix caused a lot of grief . The CHM based help solved that allowing for one set of routines to access helpdata on all systems . 4 . indexing and toc are Btree based and can be easily merged runtime from independently produced help sets . In general integrating independently produced helpfiles is a underappreciated aspect of helpfiles in general while key to open platforms . 5 . native fulltext search . An own viewer also has the ability to take advantage of extra features on top of the base system . I m not mentioning the Lazarus system in the hope you adapt it since it is at the moment too much a development system SDK oriented system the viewer is not even available as a separate package . I mainly mention it to illustrate the problems of loose html . I haven t investigate KDE Gnome Eclipse what they use as helpsystem for a while though . If I would have to restart from scratch that s where I would look first . If I had to create something myself quickly I would use zipped static html and a single gziped file with metadata indexes and the lightest browser Konquerer I could find . Not ideal not like Windows but apparently the best Linux can offer ." ] }

My scripts are based on icCube s live demo http : demo3.iccube.com icCube doc tutorial ic3report-tutorial.html ic3reportName World 20Economy . When I start my Web App with an empty Cache Cookies the App is unable to load throwing me a lot of errors similar to these : WebApp errors http : i.stack.imgur.com 37iwY.png .. . .. . The reason for these errors is the fact that the GET-requests for the resources are answered with code 401 which is a text html . This means that my WebApp is not authorized to fetch the .css and similar resources from the icCube-server . Logging into my icCube interface solves the errors as that authorizes my browser session to get data from my icCube server . Is there any workaround for this problem As far as I know the resource URIs are generated from the ic3root and ic3rootLocal passed to the ic3Start-function on the html-page which means that I can not just pack all the .css-files into my apache folder and link them . Is it possible to authorize my WebApp to get these resources based on the same authorization process used to get my report selection proxy configuration .. . Answer : It looks like because Apache does not secure the icCube URLs with its Basic Auth . configuration and let non-authenticated requests reaching the icCube server . Note 1 : You can access public HTML resources i.e . with no authentication required . For that you can use the icCube.xml property see doc . in the file . Note 2 : You can deploy the icCube Web Reporting application with you Web App HTML files in Apache and configure the Web Reporting for accessing icCube server elsewhere worth a different question . Comment : With Note 1 do you mean rewriting the ic3bootstrap.js to fetch all scripts etc . from the public directory instead of the default Also can I find documentation on your Note 2 anywhere Sounds like a reasonable solution too . Comment : Conceptually Note 1 would be very much similar to Note 2 . Note 2 your Web App will contain the icCube Web Reporting application as well . On top of my head you would need to change the location of the icCube GVI servlet to access the report definition and the OLAP engine for the MDX requests . Worth a different question .

The Application page is hosted on a server different to the IcCube-server . The server is currently a local Apache server xampp using Basic Auth to authenticate users before they can access my htdocs . I would like my Apache to do the authentication while icCube s internal authorization manages report access with only a single login being required . My application is based on the live demo for web reporting http : demo3.iccube.com icCube doc tutorial ic3report-tutorial.html provided by IcCube therefore it s using explicit JavaScript authentication it s getting the demo user data through ic3.getDemoDataSourceSettings . After trying to work through the IcCube documentation http : www.iccube.com support documentation reporting doc ic3WebAppIntegration.php on the matter I am just as confused as before .

Comment : Not sure to understand why you would need an explicit login . Apache Basic Auth . is performed meaning the GVI requests sent by your Javascript files will be authenticated on the server-side meaning the list of reports returned depends on the authenticated user . Comment : Does that mean I can leave dsSettings as undefined Comment : Ok I configured a local test install of IcCube and Apache similar to your example and it seems to work . I can t test it properly due to different problems which I m about to post in seperate questions . Thanks for the help so far Comment : Update : after testing the configurations with our live system the icCube is no longer accessible neither via standard online interface nor via apache-hosted WebApp . The interface states : HTTP ERROR : 500 Problem accessing icCube service.gwt .

I tried to access the Database throw a http access but I couldn t do it . So I tried to add jdbc4olapndriver as plugin to connect with DATABASE with same researches I found that we can use it like follows : jdbc : jdbc4olap : http : server : port OLAP msmdpump.dll . But I haven t an idea about the process of adding plugin in icCube . Any help or suggestion please thank you .. . Answer : Accessing SQL server tables is performed through a JDBC driver www http : www.iccube.com support documentation user guide schemas cubes ds database.php . So create a new SQL data source and select the SQL Server driver . Then enter amongst other the address of the SQL server and leave blank the port-number default : 1433 . Note : the URL you re talking about msmdpump.dll has nothing to do with tables in SQL server but this is related to accessing OLAP cubes for example from Excel . Hope that helps . Comment : I want to Access SSAS Database wich contain OLAP cubes with iceCube not accessing an SQL Server tables Comment : This is not possible .

Until now only with Load on startup . There are only 2 schemas that load on startup . Normally one loads in 1 minute and the other in 14 minutes . But now they both will not finish even after several hours . Last info in the log is LOAD SCHEMA PHASE I full-load started .. . .. . The machine is not busy on disk and no CPU . The Postgresql server it loads from is not running any query for the icCube server . In the builder I can open a schema but if I want to browse a simple dimension it freezes . I solved it by disabling load on startup and deployed loaded the schema from the builder . We use 64 bits Java 1.8.0 77 . Is this a known problem Other things I can check Thanks Comment : are you running out-of-memory check iccube logs for this you ll see a lot of Full GC Comment : No we are not running out-of-memory we were before but I stopped many loads . The Java settings are with 2GB max heap . According to icCube the schema s are using around 140MB and 100MB .

We have same Java version as you also 64 bits . Comment : Remco with the Community Edition the memory is limited to 512Mb just contact icCube support directly with the log files . .. . Answer : This is more likely related to this issue http : issues.iccube.com issue ic3pub-241 . This will be fixed in the upcoming 5.2 version .

Comment : Uploading a JSON array is not a recommended way to do because if you upload the JSON array you will not able to find a specific key in that array . Also when you fetch the document it will always download the whole data which also impact on the network bandwidth . Comment : I know.. . But it would be technically possible to send an array to the server just for fast transmittment and the response could be an array as well.. .

I switched to that my prompt changed and then yolk -l gives me again the same 114 packages . What is going on there Comment : Installing yolk in the virtual environment helped.. . quite strange . .. . Answer : Activating a virtualenv works by changing your shell PATH so the virtualenv s bin directory is first . This is all it does . This means that when you run python it runs the virtualenv s copy of the Python binary instead of your global system python . If you have yolk installed globally however the only yolk binary on your PATH is usr local bin yolk or some such activating the virtualenv doesn t change this because there s no yolk script in your virtualenv bin dir . And the usr local bin yolk script naturally has your system Python interpreter in its shebang line . This is why installing yolk into the virtualenv fixes the problem because it adds a yolk script in your virtualenv bin dir that has the virtualenv s python in its shebang line . If you don t want to install yolk in each virtualenv you could also just copy the yolk script-wrapper from usr local bin or wherever it is into your virtualenv s bin dir and manually change the shebang line to point to your virtualenv s python . This won t work with a --no-site-packages virtualenv though because the script wrapper then won t be able to find the actual yolk packages it needs to import If you want to use yolk within a --no-site-packages virtualenv really your only choice is to install it there .

There are one of three possibilities that I can think of that explains your issues : .. . .. . 1 . The incorrect virtualenv was sourced .. . 2 .

Answer : It looks like you are running a python 2 library with python 3 the versions need to match .", "Question : I have just started using virtualenv from this tutorial http : simononsoftware.com virtualenv-tutorial where it uses yolk to list the packages installed in the virtualenv but yolk by default is for Python 2 so I decided to upgrade with an extension for Python 3 my current version with the following command : .. . .. . pip3 install --upgrade yolk3k .. . .. . It works when I am not in the virtualenv that I called virt0 but if I am on it it gives me the error it was giving me before upgrading it to the Python 3 version .

Comment : @thefourtheye Fortunately apparently I can list the installed packages in the virtualenv virt0 using the normal pip3 with the following command : pip3 list if you someone could help me also with yolk it would be great . .. . Answer : Delete the virtualenv recreate it with Python 3 as the interpreter and install all dependencies for Python 3 such as yolk3k . The problem seems to come from the fact that you re going from a 2.x to a 3.x environment even though the virtualenv originally wasn t . That s not the intended way of using a virtualenv - a virtualenv should be tied to one particular Python version e.g . 2.7 or 3.4 with all dependencies installed for that version . So you should throw away the virtualenv and rebuild it entirely using 3.x dependencies . That should resolve any conflicting language issues .", "Question : In ubuntu lucid I have python 2.6.5 by default.I compiled python3.3.1 and set up virtualenv and wrapper such that workon envpy331 gets me to work on python3.3.1.Then I installed yolk using pip .. . .. .

Any idea why this happens Do I need to compile python3 again and set up virtualenv .. . Answer : Found the answer in a pull request on github .. . .. . This will let people and tools e.g . : https : python3wos.appspot.com know that yolk is compatible with Python 3 . Should do a release to PyPI it seems that the latest code in GitHub works with Python 3 but the last released version on PyPI 0.4.3 released 2012-02-06 doesn t work with Python 3 . .. . .. . so use the github release instead", "Question : I would like something like : .. . .. . which would return a version number .

I ll be sure to post a comment if I have any luck getting this thing working stably Comment : Any luck with getting your bot to work on Heroku Seeing the same issues myself - testing locally with ngrok works fine . Switching the messaging webhook to Heroku results in the same as the OP . Via Papertrail I see skype-sdk.messagingHandler Received request receiving data . - but nothing from console.log Tried the full URL in the server.post command but no change . My last resort is trying Azure but just curious if anyone s successfully deployed to Heroku .", "Question : From what I could understand Microsoft Bot Framework appears to be a superset of Skype Bot Framework . As in you can develop Bot Applications using MS Bot Framework with Skype as the client . So where does the difference lie .. . Answer : Right now the Skype Bot API exposes additional functionality of Skype such as audio that aren t included in the Bot Framework . You can use either one though to build a text images only Skype bot . Under the covers the Bot Framework uses the Skype Bot Framework SDK just as you might if you coded to it directly .", "Question : null .. . Answer : I ve started with just a very simple skype bot using Node.js . I would like that my bot echoes user message . Here is my server.js code : .. . .. . For testing this I use Bot Framework Emulator . When I type a message the bot responds me only with Hello World message and nothing else . Looks like it doesn t catch on message event . What s wrong here", "Question : null .. . Answer : http : docs.botframework.com builder node guides core-concepts https : www.luis.ai this is the code i have to use to make a skype bot now i want to integrate my skype bot with microsoft lui api to train my bot automatically so it can do certain works automatically any help would be greatly appreciated", "Question : I ve added my Skype bot in preview mode to my Skype account . The Skype bot seems to be properly configured as he respons to the OnContactAddedAsync event properly by replying a pre-defined message . However I cannot further test the OnPersonalChatMessageReceivedAsync handler as I m not able to message my bot i.e . Skype shows me the following : .. . .. . Screenshot of the conversation with my bot http : i.stack.imgur.com KVWC2.png .. . .. . Is it because I m not added to the bot s contact-list If so how to add somebody to the bot s contact-list using the Skype Bot SDK I have not found any way to do so in the OnContactAddedAsync handler . Is it because of some other reason .. . Answer : You need to forcefully update your Skype client to the lastet version in order to make it work . Skype v7.21.0.100 does not work . Skype v7.21.85.100 does work . Skype v7.22.85.107 does work . When you add the bot to your contact-list in the latter version it automatically accepts the request and you are able to message the bot .", "Question : I am developing a Bot using Microsoft Bot Framework In that bot will respond with sending some images to the user . I configured it with slack and skype . In slack Images are displaying but in Skype nothing coming . To send pictures I used the following syntax .. . .. . Reference dev.botfrmaework.com http : docs.botframework.com connector message-content navtitle The Text property is Markdown section clearly mention how to link an image to reply message . If I reply with just link like below skype able to understand and displaying links . But If I mention like above skype not able to understand . .. . Answer : Each channel has it s own peculiarities . Slack happens to be able to process images sent in-line as you ve shown above . However this will not work generically across all channels . To send images generically add them as attachments : Comment : Using attachments is good but in my case I am using Form Builder and in the middle of the conversation depends on user choice bot will display some information along with images . Example Bot will display list of pizzas with images for each pizza . The output would be like below 1 . PizzaA image of PizzaA 2 . PizzaB image of PizzaB . . . etc .", "Question : null .. . Answer : I want to open Skype Android app and redirect user to the bot conversation screen of XYZ Bot . As it happens while redirecting user to a chat conversation with particular Skype user through below URI ." ] }

Answer : Since you are using wsDualHttpBinding then both your server and your client need to be reachable on the ports specified in your config . This is the reason it works on your local machine as you dont have any port issues . The timeout is consistent with a firewall blocking or your server unable to route back to your client . If your client can easily be reached by adding a firewall or port forwarding rule then wsDualHttpBinding may still be suitable - otherwise using wsDualHttpBinding is probably not ideal .

Answer : wsDualHttpBinding doesn t support transport security . MSDN : .. . .. . The WSDualHttpBinding provides the same support for Web Service protocols as the WSHttpBinding but for use with duplex contracts .

Answer : Per the original question : .. . .. . When using WSDUALHTTPBINDING with message security is it recommended to use Transport security also i.e SSL As stated WSDualHttpBinding does not support security at the Transport level . So the original question is sort of defeated . Per the update to the question : .. . .. . Update now that i know wsduallhttpbinding does not support transport security is message security as secure or should i use another binding that supports ssl under my scenario .. . .. . Message level security is actually superior as it provides end-to-end security . Transport level security only provides point-to-point security . Message security directly encrypts and signs the message so even routing the messages through intermediate systems does not break the security . You also get the additional bonus that message security is transport-independent so it can be used with any transport protocol . MSDN actually recommends using message security in internet scenarios : .. . .. . Use message security in the following scenarios : .. . .. . You are sending a message to a WCF service and the message is likely to be forwarded to other WCF services or may be routed through intermediate systems . Your WCF clients are accessing the WCF service over the Internet and messages may be routed through intermediate systems .

I am not really sure if soapUI is supprting WSDualHttpBinding . I really appreciate any hints articles or solutions . .. . Answer : I m not sure dual binding is interoperable with clients other than WCF . I read once that Metro WSIT stack for Java supports it . But the safest will be to use a WCF client . The reason is that the dual binding assumes the client should get messages from the server in a callback endpoint . This is not so standard also in terms of defining this properly in a WSDL file . You might be able to get away with it by setting up a dedicated-server on your client-side waiting for the WCF response . But the wiring will be time consuming . If you own the server you might want to make it more explicit that the client is supposed to have a server endpoint to get callbacks to or you could use some WCF router as an intermediate .

I m sorry if i m not been clear enough my English is not so good . sry and thanks again a lot . .. . Answer : netTcpBinding is better for duplex communication communication with callbacks and it s more performant than WSDualHttpBinding which is the preferred binding for duplex communication over HTTP . But you shouldn t really use netTcpBinding over the internet although you technically can and it might work but the ports that netTcpBinding uses may be and usually are blocked by firewalls on the internet . When you send something across the internet it makes lots of hops and goes through lots of routers and firewalls and there is no guarantee that those routers and firewalls will have all ports open . But if you can open the ports for netTcp it s TCP 808 on both the client and server endpoints usually done by port forwarding on the router it may work but the general advice is not to use netTcpBinding over the internet . Having said that I have used it a couple of times for my services and my clients have been able to consume the service over the internet without any problems-after I forwarded the ports on both the client and server ends . In general for duplex communication over the internet you have the WSDualHttpBinding http : msdn.microsoft.com en-us library system.servicemodel.wsdualhttpbinding.aspx and if you have a Silverlight client Silverlight doesn t support WSDualHttpBinding you can use PollingDuplexHttpBinding http : msdn.microsoft.com en-us library system.servicemodel.pollingduplexhttpbinding 28v vs.95 29.aspx . I also recommend you read this http : www.code-magazine.com article.aspx quickid 0605051 page 3 . EDIT : .. . .. . To change that example to use netTcpBinding just change the bindings in the config file to use netTcpBinding instead of wsDualHttpBinding . Have a look at this article http : www.codeproject.com Articles 25261 A-WCF-WPF-Chat-Application it does what the link you posted does with netTcpBinding and more explanation . EDIT 20 06 2012 : .. . .. . Making myself clear : I just could not make it work over the internet . Can you guys show me how can i change my configurations Web.config e App.config to use netTcpBinding and work over the internet Seems that you were able to get the service to work with netTcpBinding in LAN so your earlier problem is now fixed and you re now having trouble hosting the service in IIS and publishing it online . When your service works in a LAN it will work over the internet once you host it in IIS and forward the appropriate ports on the clients and servers routers this is a common scenario and is documented well online . To do this You must host your service as an application in your IIS website . You need to make sure your service has a .svc file that points to the location of the service then copy the contents of the App.Config Service config file to a new web.config in the same physical directory as your App.config and also remove the host baseAddresses section in the newly created web.config point the physical path of the application to the location of this service on your service host computer . Once that s taken care of just be sure to edit the default website bindings to enable the specific bindings your service uses for netTcpBinding go to : Website - Edit Bindings.. . - Add.. . then choose net.tcp and assign it the ports . Then on your application go to Advanced Settings and enable net.tcp netTcpBinding service will typically have http net.tcp as it s enabled protocols . If you run into teething errors make sure the default app pool or which ever application-pool your website is using has the required permissions to access and read the physical directory on the server in which the service resides . Please read this http : blogs.msdn.com b santhoshonline archive 2010 07 01 howto-nettcpbinding-on-iis-and-things-to-remember.aspx and this http : galratner.com blogs net archive 2010 10 08 setting-up-a-nettcpbinding-enabled-wcf-service-in-iis-7.aspx asking me to elaborate would just be repeating what they re saying . EDIT 21 06 2012 : .. . .. . I just downloaded your service and hosted it in IIS and it s hosted fine since its using HTTP and not nettcp then that means it works perfectly fine on the internet . If your service is something simple and you don t expect to do heavy processing with it by the looks of it you re just trying to get the list of clients connected to it then stick with wsDualHTTPBinding since the HTTP protocol will work in any environment and you don t have to worry about firewalls as you would with netTcpBinding . This is all I did to host the service in IIS and make it available over the internet : .. . .. . 1 . Go to DefaultWebsite in IIS right-click add application under Alias just give your service any name you wish to be able to see in the URL . Select Default App Pool or ASP.NET 4.0 app pool . 2 . Point the physical path to where your .svc file is on your computer for me its : .. . .. . C : Users MyPC Documents DualCommunicationTest.Server WcfServiceApp .. . .. . 1 . Under enabled protocols ensure that you have HTTP on port 80 or any other port for example 8085 but you will need to forward this port on your router to the Service host computer . If your Service host is on IP 192.168.1.4 in your LAN then on your router forward port 80 or whatever port you use-say 8085 to computer 192.168.1.4 . And it s that easy . Comment : Nice reading indeed.. . ok i don t know anymore if i m going for netTcp or wsDual but could you please help me to make it work I m happy just in puting the example implemented in the link above to work.. . Comment : @TanielianBarreira I just looked at the article it seems well written what exactly is the problem It s implementing a simple chat service by the looks of it there are lots of examples on callbacks in WCF . the gist of the idea is that the client calls some operation on the service and the service can in turn call a method on the client this is the callback so the client will temporarily be like a server itself . The methods in ChatService are what clients call on the server and the methods in IChatServiceCallback is what the service invokes on the clients . Comment : @TanielianBarreira look at my update .

In my case both client and service are located on an intranet . If the service was on a webserver over the internet would the answer be different Update now that i know wsduallhttpbinding does not support transport security is message security as secure or should i use another binding that supports ssl under my scenario .. . Answer : The wsDualHttpBinding doesn t support Transport security as explained here : http : msdn.microsoft.com en-us library ff648589.aspx .. . .. . Binding limitations : Transport security does not work with wsDualHttpBinding . You can rely on Message security . It uses WS-Security to protect each message . UPDATE : As I said you can rely on Message security it provides end-to-end security . You can find here the detailled explaination : http : msdn.microsoft.com en-us library ff648863.aspx .. . .. . The downside of Message security is mainly that it is a bit slower as every message as to be encrypted but don t worry it is secure enough you don t need to change bindings .", "Question : I have to find a way to connect a WCF service to a Java client . I can not change the code of the WCF service and it only offers NetTcpBinding or wsDualHttpBinding .. . .. . One work-around would be to create a C communication channel to manage the communication between the service and the client . However I have no experience with C and I m sure this will take a long time . What would be the best way to deal with this Are there any available communication channels and offer this already Thank you in advance Comment : Did you ever find a resolution to this .. . Answer : The problem you have is neither of the bindings offered support non-wcf clients . I can t see any way you can communicate with this service without as you say put an intermediary service in between . The perfect candidate for this is WCF Routing protocol bridging http : msdn.microsoft.com en-us vs2010trainingcourse whatsnewinwcf4 topic17.aspx - which is exactly what it sounds like - translation of one protocol to another . In this case you are not going between protocols but WCF bindings . Your solution would have to use basicHttpBinding which ships with WCF and exposes services over soap 1.1 .

Answer : When java compiler converts your source code to byte code it handles synchronized methods and synchronized blocks very differently . When the JVM executes a synchronized method the executing thread identifies that the method s method info structure has the ACC SYNCHRONIZED flag set then it automatically acquires the object s lock calls the method and releases the lock . If an exception occurs the thread automatically releases the lock . Synchronizing a method block on the other hand bypasses the JVM s built-in support for acquiring an object s lock and exception-handling and requires that the functionality be explicitly written in byte code . If you read the byte code for a method with a synchronized block you will see more than a dozen additional operations to manage this functionality . This shows calls to generate both a synchronized method and a synchronized block : .. . .. . The synchronizedMethodGet method generates the following byte code : .. . .. . And here s the byte code from the synchronizedBlockGet method : .. . .. . .. . .. . One significant difference between synchronized method and block is that Synchronized block generally reduce scope of lock . As scope of lock is inversely proportional to performance its always better to lock only critical section of code . One of the best example of using synchronized block is double-checked-locking in Singleton pattern http : docs.oracle.com cd E19205-01 820-0619 gedig index.html where instead of locking whole getInstance method we only lock critical section of code which is used to create Singleton instance . This improves performance drastically because locking is only required one or two times .

First when one thread is executing a synchronized method for an object all other threads that invoke synchronized methods for the same object block suspend execution until the first thread is done with the object . Second when a synchronized method exits it automatically establishes a happens-before relationship with any subsequent invocation of a synchronized method for the same object . This guarantees that changes to the state of the object are visible to all threads .

Synchronizing constructors doesn t make sense because only the thread that creates an object should have access to it while it is being constructed . Synchronized Statement .. . .. . Unlike synchronized methods synchronized statements must specify the object that provides the intrinsic lock : Most often I use this to synchronize access to a list or map but I don t want to block access to all methods of the object . Q : Intrinsic Locks and Synchronization Synchronization is built around an internal entity known as the intrinsic lock or monitor lock . The API specification often refers to this entity simply as a monitor . Intrinsic locks play a role in both aspects of synchronization : enforcing exclusive access to an object s state and establishing happens-before relationships that are essential to visibility . Every object has an intrinsic lock associated with it . By convention a thread that needs exclusive and consistent access to an object s fields has to acquire the object s intrinsic lock before accessing them and then release the intrinsic lock when it s done with them . A thread is said to own the intrinsic lock between the time it has acquired the lock and released the lock . As long as a thread owns an intrinsic lock no other thread can acquire the same lock . The other thread will block when it attempts to acquire the lock . Cross check different outputs with synchronized method block and without synchronization .

Answer : Someone more experienced with multithreading should feel free to step in but I believe this would remove the versatility of synchonized blocks .

Answer : What is the synchronized keyword Threads communicate primarily by sharing access to fields and the objects reference fields refer to . This form of communication is extremely efficient but makes two kinds of errors possible : thread interference and memory consistency errors . The tool needed to prevent these errors is synchronization . Synchronized blocks or methods prevents thread interference and make sure that data is consistent . At any point of time only one thread can access a synchronized block or method critical section by acquiring a lock . Other thread s will wait for release of lock to access critical section . Once the lock is released by current owner thread with notify or notifyAll call one of thread s will acquire the lock to access critical section guarded by synchronized keyword . When are methods synchronized Methods are synchronized when you add synchronized to method definition or declaration . You can also synchronize a particular block of code with-in a method . What does it mean pro grammatically and logically It means that only one thread can access critical section by acquiring a lock . Unless this thread calls notify or notifyAll all other thread s will have to wait to acquire a lock . They don t have access to enter critical section with out acquiring lock . This can t be done with a magic . It s programmer responsibility to identify critical section s in application and guard it accordingly . Java provides a framework to guard your application but where and what all sections to be guarded is the responsibility of programmer .

Answer : As already said here synchronized block can use user-defined variable as lock object when synchronized function uses only this . And of course you can manipulate with areas of your function which should be synchronized . But everyone says that no difference between synchronized function and block which covers whole function using this as lock object . That is not true difference is in byte code which will be generated in both situations . In case of synchronized block usage should be allocated local variable which holds reference to this .

Comment : A benefit to the consumer of the API is that using the synchronized keyword in the method declaration also explicitly declares that the method synchronizes on the object instance and is presumably thread-safe . Comment : I know this is an old question but synchronizing on this is considered in some circles to be an anti-pattern . The unintended consequence is that outside of the class someone can lock on an object-reference that is equal to this and prevent other threads from passing the barriers within the class potentially creating a deadlock situation .

Since the length of the bytecode is a factor in whether a method gets in-lined moving the block to the method-signature could be the difference in decision . In theory anyway .

A synchronized method can only use this or the corresponding Class instance for a synchronized class-method . For example these are semantically equivalent : .. . .. . The latter is more flexible since it can compete for the associated lock of any object often a member variable . It s also more granular because you could have concurrent code executing before and after the block but still within the method . Of course you could just as easily use a synchronized method by refactoring the concurrent code into separate non-synchronized methods . Use whichever makes the code more comprehensible .

So my question is why java didn t go for synchronized wait notify methods removing the restriction of calling these methods from synchronized block or methods . In case these are declared as synchronized it would have automatically taken the monitor access . .. . Answer : The wait-notify model of synchronization requires that you acquire the monitors on an object first before proceeding to perform any work . It is different from the mutual exclusion model that is used by a synchronized block . The wait-notify or mutual cooperation model is typically used in a producer-consumer scenario where one thread produces events that are consumed by another thread . Well-written implementations will strive to avoid the scenarios where a consumer is starved or the producer overruns the consumer with too many events . To avoid this you would use the wait-notify protocol where .. . .. . the consumer wait s for the producer to produce an event . the producer produces the event and notifies the consumer and then usually goes to sleep until it is notified by the consumer . when the consumer is notified of an event it wakes up processes the event and the notifies the producer that it has finished processing the event . You could have many producers and consumers in this scenario . Acquiring the monitor through the mutual exclusion model on wait notify or notifyAll is bound to destroy this model since the producer and the consumer do not perform the waiting explicitly . The underlying threads will be present in either the wait set used by the wait-notify model or the entry set used by the mutual exclusion model of a monitor . Invoking notify or notifyAll signals thread s to be moved from the wait set to the entry set of the monitor where there may be contention for the monitor among several threads and not just the recently notified one . Now when you want to automatically acquire the monitor on wait notify and notifyAll using the mutual exclusion model it is usually an indication that you do not need to be using the wait-notify model . This is by inference - you would typically signal other threads only after doing some work in one thread i.e . on a change in state . If you are automatically acquiring the monitor and invoking notify or notifyAll you are merely moving threads from the wait set to the entry set without any intermediate state in your program implying that the transition is unnecessary . Quite obviously the authors of the JVM were aware of this and have not declared the methods as synchronized .

P S : Sorry the the unclear code this is how it should look like Comment : It is difficult to understand what you mean . Can you illustrate your question with some code Comment : I think Block B would also be synchronous . I believe in java all code is executed synchronously by default . If B is contained in A and A and B are executed synchronously then A will not finish until after B finishes . .. . Answer : Depends . If the block B is a block of code within method like this then yes.. . it will be synchronized . If it s another method like the following then no : .. . .. . Unless methodB is also marked synchronized or called from another synchronized method eg public synchronized methodC or another synchronization mechanism is used then methodB is not synchronized . Those are just the simplest cases . You re better off posting example code since block is not well defined by default and the type of synchronization lock implicit on this via synchronized method vs . explicit object lock makes a difference . But your last line sounds like you re asking about synchronous vs . asynchronous execution of code which while related to threading and synchronized blocks is a different concept . In that case it depends on what happens in block A .. . if new threads are created to execute block B then anything can happen with the timing of code execution . If no threads are created it s safe to assume that block A will not complete before block B . Edit : based on code now posted .. . the synchronized A block will only ensure the Timer threads get created one at a time . But unless there s something special about the Java Timer framework there s nothing there that will prevent two threads from executing the B block in the run method simultaneously .. . so make sure that the contents are thread safe . That is don t assume that just because different instances of Timer are created in a synchronized block with the same delay they won t get into the run method at the same time .

Note : I ve already seen this http : stackoverflow.com questions 6124855 unloading-a-jvmti-agent-at-runtime but thought there might be some normal way to do it that isn t in the JVMTI standard . .. . Answer : 1 . You can only inject deploy an agent either at start time http : docs.oracle.com javase 7 docs platform jvmti jvmti.html onload of the JVM by passing the argument -agentlib : agent-lib-name options or -agentpath : path-to-agent options . The other way is through Java itself . This depends heavily on the JVM for that reason it is out of JVMTI specification scope . For instance if there is the VirtualMachine http : docs.oracle.com javase 6 docs jdk api attach spec com sun tools attach VirtualMachine.html class through the method loadAgentPath agentPath options http : docs.oracle.com javase 6 docs jdk api attach spec com sun tools attach VirtualMachine.html loadAgentPath 28java.lang.String 20java.lang.String 29 . If you want to execute this from within the native JVMTI code you would need to do Bytecode instrumentation . 2 . I am not sure similar to 1 . you could run the Java unload method through Bytecode instrumentation . If dlclose works I do not see a problem in doing that .

You have to set the system property java.system.class.loader to be the name of your custom class loader for your target JVM . see doc here http : download.oracle.com javase 6 docs api java lang ClassLoader.html getSystemClassLoader 28 29 .. . .. . Java s builtin Class loaders always checks if a class is already loaded before loading it . Reloading the class is therefore not possible using Java s builtin class loaders . To reload a class you will have to implement your own ClassLoader subclass . In your case you have to implement a ClassLoader which has ClassLoader.getSystemClassLoader has parent . Even with a custom subclass of ClassLoader you have a challenge . Every loaded class needs to be linked . This is done using the ClassLoader.resolve method . This method is final and thus cannot be overridden in your ClassLoader subclass . The resolve method will not allow any given ClassLoader instance to link the same class twice . Therefore everytime you want to reload a class you must use a new instance of your ClassLoader subclass . This is not impossible but necessary to know when designing for class reloading . see Dynamic Class Reloading http : tutorials.jenkov.com java-reflection dynamic-class-loading-reloading.html Comment : This does not help with JVMTI agents which are native-code . Detaching from the JVM doesn t cause the JVMTI agent to be unloaded . Comment : I dont say that . The code example is just here to show how to load the agent . Unloading agent from the JVM is the same problem that unloading classes . The only solution is to use your own Class loader . Comment : If you look at the attach doc it clearly states that loadAgent is used to load agents that are written in Java while loadAgentLibrary and loadAgentPath are used to load JVMTI agents that are native-code . Since the JVMTI agents are native-code and not Java classes your discussion of class loaders does not apply .

So I have few questions about them . 1 . What is the difference between JDI java debugger interface JWDP javaagent and native agent JVMTI . and where does the java instrumentation API fit in picture . 2 . I am using JDI to intercept exceptions in target java application . but I found out that JDI is not good enough if we talk about how it impacts the performance of target app . I read that most good applications does this with combining JVMTI with byte code instrumentation . But I can t understand how byte code instrumentation can be used with JVMTI . So how can we do byte code instrumentation along with JVMTI any example will be helpful . 3 . Can we instrument both byte code and machine code in java 4 . Can static byte code-analysis be used along with JVMTI . If yes then how If any question is irrelavent or wrong let me know . .. . Answer : 1 - I think that this site explains the distinction pretty well : http : docs.oracle.com javase 1.5.0 docs guide jpda architecture.html - these are basically 3 layers of abstraction built on top of each other with JVMTI interfacing directly with the running JVM then JDWP being used as a communication protocol then JDI as an interface to that remote JVM . You can use a javaagent to perform bytecode instrumentation orthogonal to the implementation of these 3 things . 2 - I think that the most performant way to do this would be to instrument all code to add a try-catch in each method to handle an exception - when the exception is caught you handle it however you wanted to then re-throw it . The easiest way to do instrumentation is with the javaagent approach then using javaassist or asm or whatever . You can instrument bytecode from JVMTI too but it is much more cumbersome . If you only care about specific exceptions namely those that are explicitly thrown and not those that are thrown internally by the interpreter like NullPointerException ArrayIndexOutOfBoundsException etc then the easiest way to handle these would be to intercept ATHROW instructions the instruction used to throw an exception . I have no specific experience but it might be reasonable to create a JVMTI agent that is registered for the Exception event http : docs.oracle.com javase 7 docs platform jvmti jvmti.html Exception but I am not sure of its performance could be just as slow as your JDI approach could be better . 3 - No : you can only instrument bytecode running in Java . If you wanted to instrument the machine code you could try to do that with something like pin but I think this is probably getting way out of hand for what you are looking for . 4 - Sure : what sort of static-analysis are you interested in You could certainly use something like soot and also use JVMTI . Comment : Thanks a lot for your answer . About the static-analysis My use-case is only that if I can find out pieces of code which can throw any exceptions without actually running the target application . Anyway I am not going to use byte code-analysis in near future . I was just curios if byte code-analysis can be done using JVMTI . If you could point out to some tutorial for this that will be helpful . I already searched google for this but couldn t find anything . Thanks . Comment : If all that you are interested in is the exact site that could throw the exception e.g . throw new MyException then you could use ASM to simply detect the ATHROW instruction and then emit some instrumentation around it . However if your goal is to more broadly find all possible call sites that might call code that might throw an exception then you need to build a static call-graph .

One of the required capabilities is this : only when an exception is thrown I need to be able to query the local-variables for all frames in the call stack at the time the exception is thrown . This capability is not available in standard Java or reflection . Thus I m looking at the following idea : .. . .. . Write a simple JVMTI shared object in C .. .

Code in the JVMTI lib suspends the Java thread that threw the exception inspects the stack to pull out the locals stores them somewhere accessible and resumes the Java thread .. . .. . Other than in this one scenario JVMTI would not be used at all . Code could potentially run for days without throwing an exception and I would hope it would run as fast as non-JVMTI enabled code .

Answer : JVMTI capabilities you mentioned will not prevent from JIT compilation . However certain optimizations will be disabled e.g . Escape Analysis and dead locals elimination . Also every thrown exception will cause deoptimization switching to interpreter . Nevertheless overall performance overhead should be negligible . Comment : why do you say every thrown exception will cause a switch to the interpreter Comment : If you are going to handle exceptions by JVMTI function you ll have to set up Exception callback . Whenever exception occurs JVM will deoptimize current frame and call this callback . Or were you planning to do that some other way Comment : no you re absolutely right . I found what seemed to be a more direct way though by creating a dummy function and using JVMTI to set a breakpoint in the dummy function .

Comment : +1 cause you r question produced such a good answer below : - .. . Answer : OpenGL http : en.wikipedia.org wiki OpenGL .. . .. . OpenGL Open Graphics Library is cross-platform API for rendering 2D and 3D graphics . The API mainly tries to focus on using the GPU to achieve hardware-accelerated http : en.wikipedia.org wiki Hardware acceleration rendering . OpenGL-ES http : en.wikipedia.org wiki OpenGL ES .. . .. . OpenGL-ES OpenGL for Embedded Systems is a subset of OpenGL designed for use on embedded systems like smartphones tablets game consoles etc . WebGL http : en.wikipedia.org wiki WebGL .. . .. . WebGL Web Graphics Library is a JavaScript API for rendering 2D and 3D graphics . WebGL also uses the GPU as much as it is possible through the browser . WebGL is based on OpenGL-ES http : en.wikipedia.org wiki OpenGL ES . Take in mind that they might have the same functions though WebGL isn t OpenGL or OpenGL-ES . WebGL is only based on OpenGL-ES . GLU http : en.wikipedia.org wiki OpenGL Utility Library .. . .. . GLU OpenGL Utility Library is a graphics library for OpenGL consisting of utility functions which can be used with OpenGL . The functions mainly focus on primitive rendering and mapping between screen- and world-coordinates etc . GLEW http : en.wikipedia.org wiki OpenGL Extension Wrangler Library .. . .. . GLEW OpenGL Extension Wrangler Library is a cross-platform library helps in querying and loading OpenGL Extensions . GLUT http : en.wikipedia.org wiki OpenGL Utility Toolkit .. . .. . GLUT OpenGL Utility Toolkit is a library of utilities for OpenGL which primarily focuses on window definition window control and monitoring of keyboard and mouse input . SDL http : en.wikipedia.org wiki Simple DirectMedia Layer .. . .. . SDL Simple DirectMedia Layer is a cross-platform development library designed to provide low-level access to audio keyboard mouse joystick and graphics hardware via OpenGL . SDL can also be used for other graphics API s such as DirectX etc . QT http : en.wikipedia.org wiki Qt 28framework 29 .. . .. . QT is a cross-platform application development framework widely used for the development of GUI programs in which case it is known as a widget toolkit and also used for developing non-GUI programs such as console tools and servers . Conclusion .. . .. . OpenGL is an API for rendering 2D and 3D graphics . OpenGL-ES is a subset of OpenGL targeting embedded systems . WebGL is a JavaScript API for rendering 2D and 3D graphics based on OpenGL-ES . GLU is a utility library for OpenGL which mainly contains mapping functions . GLEW is a utility library for OpenGL which can handle loading of OpenGL Extensions . GLUT SDL is a library for handling various things like window keyboard and mouse control as well as listening . QT is a framework mainly for creating GUI . Thereby GLU GLEW GLUT is simply utility libraries for OpenGL which requires OpenGL if not they aren t for much good . SDL doesn t require OpenGL and isn t directly an OpenGL utility library mainly but it can be used with OpenGL but also with other things as well . Comment : Upvoted for mostly correct answer but SDL doesn t really require GL . It may use many different graphics backends . Comment : @keltar thanks for the response I fixed that part of my answer . Comment : You should mention that Qt has functions for using OpenGl . As of Qt 5.1 Qt Quick 2 only uses OpenGl and so now QOpenGL classes are a core part of Qt in QtGui module . Also QtCanvas implements WebGL for non web-applications and Qt3D is a new module for games and other applications that involve pairing 3D content with other functionality .", "Question : I have been working in Optix for my ray tracing project i went through its classes and function I know that all the display function and call backs are handled in glutmainloop and it will never end my question is I cannot find any function or .c file where glutmainloop is defined is it hidden Can anyone help me .. . Answer : glutMainLoop is a function from the GL Utility Toolkit GLUT . On Windows the library gets linked in and thus no source code is provided .

It s a single C C++ cross-platform file to add to your project.It has no init and no main loop . .. . Answer : GL is an API and GLU is an utility library on top of GL . It s completely operating-system independent . OpenGL initialization and extension fetching are platform dependent operations . Therefore you can do about nothing with OpenGL alone . GLUT is fast insufficient and terribly poor library and about only it does is that it initializes the opengl context and provides some primitive mouse keyboard input modules to get you ongoing . Win32 provides tools to initialize opengl context as well . For linux you could check out GLX . Also if you want a system independent way of doing it then you could check out SDL .

Is anyone here who can explain the difference between this header-files and what I have to do with it I goggled much time but on different sites there are much more confusing words like glee or glut . .. . Answer : gl : This is the base header file for OpenGL version 1.1 . That means if you want to use any functionality beyond version 1.1 you have to add any extension library on this . glew : OpenGL Extension Wrangler Library . This is a cross-platform library for loading OpenGL extended functionality . When you initialize this library it will check your platform and graphic card at run-time to know what functionality can be used in your program . glu : This is OpenGL utilities library which has been not updated for long time . Don t need to use this header file . glut : OpenGL Utility Toolkit for Windowing API . This is good for small to medium size OpenGL program . If you need more sophisticated windowing libraries use native window system toolkits like GTK or Qt for linux machines . glfw : OpenGL Frame Work .

Comment : When I installed Visual Studio 2012 I don t think the OpenGL development files were in there . I ll double-check but I m pretty sure OpenGL was not in there . I installed VS 2010 in the meantime so I can get started on my school projects . Comment : Yes they re definitely there . Visual C++ comes with the OpenGL headers in GL gl.h and ships the linker symbol library opengl32.lib .. . Answer : OpenGL should be present already - it will probably be Freeglut GLUT that is missing . GLUT is very dated now and not actively supported - so you should certainly be using Freeglut instead . You won t have to change your code at all and a few additional features become available . You ll find pre-packaged sets of files from here : http : freeglut.sourceforge.net index.php download If you don t see the lib folder it s because you didn t download the pre-packaged set . Martin Payne s Windows binaries is posted at above link and works on Windows 8.1 with Visual Studio 2013 at the time of this writing . When you download these you ll find that the Freeglut folder has three subfolders : - bin folder : this contains the dll files for runtime - include : the header-files for compilation - lib : contains library files for compilation linking .. . .. . Installation instructions usually suggest moving these files into the visual-studio folder and the Windows system folder : It is best to avoid doing this as it makes your project less portable and makes it much more difficult if you ever need to change which version of the library you are using old projects might suddenly stop working etc . Instead apologies for any inconsistencies I m basing these instructions on VS2010 .. . - put the freeglut folder somewhere else e.g . C : dev - Open your project in Visual Studio - Open project properties - There should be a tab for VC++ Directories here you should add the appropriate include and lib folders e.g . : C : dev freeglut include and C : dev freeglut lib - Almost Final step is to ensure that the opengl lib file is actually linked during compilation . Still in project properties expand the linker menu and open the input tab . For Additional Dependencies add opengl32.lib you would assume that this would be linked automatically just by adding the include GL gl.h to your project but for some reason this doesn t seem to be the case .. . .. . At this stage your project should compile OK . To actually run it you also need to copy the freeglut.dll files into your project folder Comment : Just wanted to add that you need to copy freeglut.dll to the Debug folder in which the .exe of your project is there . Comment : Don t try to build glut or freeglut by yourself because the only consequence is a pile of linking errors crying out for OpenGL functions not found .

Answer : glutTimerFunc 1000 30 mytimer 0 tells GLUT from now on call mytimer every 1000 30th milliseconds . You probably want to call it from main .

Comment : it s kinda too late for me switching back to SDL or anything similar . I can t imagine how that would be a significant problem . GLUT is for window setup and management switching managers should only require fairly localized changes . Unless you re dependent on GLUT-specific features like sRGB framebuffers and the like . .. . Answer : Ultimately no . The best you can do is call glutReshapeWindow to force it to a particular size whenever you detect that it has been resized . But that s about it . And if you do that you need to do some infinite-loop prevention by ensuring that you only call glutReshapeWindow if the new size isn t the same as the desired . This won t prevent the user from trying to resize it but it ll prevent them from succeeding . Possibly . Remember : GLUT is designed for demo applications and simple test-beds .

Answer : I have been developing a somewhat complicated app on core python-2.6 and have also managed to use pyinstaller to create an executable for deployment in measurements or distribution to my colleagues .

The way I ve upgraded on my local machine was to delete the folders of these libraries and then manually install the newer versions . However this does not work for machines where I do not have root access . While trying to find a workaround I found ActivePython .

Answer : You can try installing Django in a virtualenv . A virtualenv lets you decide where you want to install Python packages . You can install it in the directory you want if you have the required permissions . A virtualenv can either be a clean room environment excluding all system-wide modules or use those modules as well as modules only available within the virtualenv . Placing a clean room virtualenv in a location where you are absolutely sure that you will have the required permissions can help you understand whether it s an issue with file system permissions or something with old .py or .pyc files located somewhere you forgot about . You can use the installed Python modules in a virtualenv in different environments if you add the appropriate directories within the virtualenv to PYTHONPATH so you don t need to worry that if you use virtualenv you will not be able to use Eclipse or any other IDE editor anymore . You just need to configure it appropriately . Comment : please read my edit Comment : In the python shell type django . file to see where Django is located just to make absolutely sure that you added the correct directory in PyDev .", "Question : i have recently asked a question http : stackoverflow.com questions 7206762 why-does-django-open-with-pype .. . .. . I rechecked and it seems that pydev does not detect django either but i can import django in activepython interpreter . so if i installed django using pypm would pydev detect it Comment : You can install Django globally if the user-site path which is where pypm installs into is not recognized by pydev : pypm -g install django Comment : @Sridhar Ratnakumar thank you so much sir i have fixed this issue this afternoon what i did is in the window preferences i pointed pydev to the site packages...this has been a complete headache for me some told me to uninstall django the others told me to uninstall python...i didn t even need to uninstall django...i wish you where here yesterday to save me from all of this : D Comment : look at the theories man bit.ly pg73m6 http : bit.ly pg73m6 and the problem is silly yet i wouldn t have received a good answer if i haven t started a bounty .. . Answer : PyDev currently doesn t pick additions to the PYTHONPATH automatically so you have to re-configure your interpreter within PyDev even if only the PYTHONPATH changed . See : http : pydev.org manual 101 interpreter.html Comment : sir I tried to change the path didn t work so since i have another problem with django as described in the question I wounder if i uninstalled activepython django and installed django using pip would it work and how about keeping the current django and installed a 2nd one Comment : Adding a 2nd one should be OK you can have many at the same time . Still not recognizing is strange.. . You should check if your PYTHONPATH is really correct i.e . : the folder on the PYTHONPATH should be something as mypath considering that django is in mypath django init .py . Comment : Another thing make sure that django is not installed as a zip file i.e . : its contents should be uncompressed . If that still doesn t work it may be that there s some problem in some internal cache in that case you can try restarting Eclipse after configuring the shell .

Answer : I would guess that windows has associated all .py files with your text-editor pype . So when a script tries to run another script by asking windows to open the .py file it just pops up in your editor instead of executing . Right click on a .py file in windows-explorer choose open-with and tell it to always open .py files with your python interpreter python.exe instead of pype . See if that fixes it . Comment : i did that and now when i run setup.py install the file setup.py opens up with the interpreter lol instead of installing django : D I know that there s a problem with my pc not just a silly mistake i just don t know what it is Comment : Muck with your windows settings and your python install maybe reinstall python until when you double-click a .py file in file explorer and the python script runs try hello world then I bet you ll be good . Comment : man i not a newbie i can run any python script you know just forget it I ll use turbo gears instead or better yet learn-ruby-on-rails and just forgot about django - unless someone can give an answer that is worth 50 pts - python is working PERFECTLY django is not that s all i can say I m even ready to give you team viewer access to my pc just to prove it s not a silly issue Comment : @Eli : I know it must be frustrating to run into such a basic problem . But that doesn t mean that you have to be so aggressive towards people who want to help he is only trying and you d be surprised how many times even the biggest experts make stupid newbies mistakes . Comment : So sorry sir for everything i said", "Question : I am new to python scripting and started to look into a script to allow me to SSH to a box and check it is still running .

After a survey I know there are two libraries exist which might meet my requirement which are MIDIutil and pygame . However MIDIutil seems only output the midi file and not able to output the real-time signal . On the other hand Pygame is a real pain of Mac Mountain Lion user . I have working on it for 1 week and still stuck at same stage . Unable to initial midi the log constantly shows unable to find pypm module . What is pypm module I ve tried to find solution on google non of them able to solve the problem I faced .

Thank you very much . James .. . Answer : Python-RTMIDI http : pypi.python.org pypi python-rtmidi is in alpha stages haven t tried it yet myself but it s my primary choice for an upcoming hardware synth editor project It s a C++ Python extension so it might not be painless to setup but then you get CoreMIDI as well as optional JACK support might be worth your while ." ] }

Help me to solve this issue and how can I print values of NSNumber .. . Answer : The best way to debug EXC BAD ACCESS : .. . .. . 1 . If you are not using XCode 4 then upgrade . 2 . In XCode 4 press CMD-I to run Instruments . 3 . Select the Zombies profile . Background : EXC BAD ACCESS means you are sending a message to a deallocated object . Zombies turns on the zombie feature so that objects with a retain count of 0 are not deallocated but kept as a zombie . The NSZombie class raises an exception whenever a message is sent to it - thus it can be trapped and identified the point of origin . 4 . Run your app via Instruments . When it crashes Instruments will be brought to the foreground with a pop-up callout that indicates the memory that was freed but accessed . 5 . You can click the little arrow in the lower right corner this will give you that memory s alloc retain release history and the code that performs the action . Click on the source column it will take you to that line in the code .

For example you would want to add something like the following : .. . .. . There is also an API call that you can use to programmatically do this .

Now all the requests like this socket.io xhr-polling 40pt1SBvasfDuwctz4Ma for the service appear to take 20.000 seconds . Is there a way to set up newrelic so it would correctly show request times served by socket.io .. . Answer : The software is actually working as intended . When using XHR-polling with Socket.IO the default polling duration is 20 seconds . Therefore the connection is held open for 20 seconds which is the reason why New Relic reports it as so .", "Question : We are running Elasticsearch with the NewRelic Java agent installed . We want to record custom metrics without changing anything in ES . I know the NewRelic proposed way to do this is Steven Eksteens Elasticsearch Plugin http : newrelic.com plugins steven-eksteen 134 but it s Ruby based and we try to avoid adding another language to our stack . I tried to replicate Stevens efforts in Python using the NewRelic Python agent and the newrelic.agent.record custom metric function : .. . .. . This works fine . Only problem : If configured to use the same app name as the existing java-agent controlled App it registers a new app in NewRelic with the appendix Python . What I want is to add the metrics to the original one . Is this possible .. . Answer : Applications in the New Relic Dashboard have to be the same language to be consolidated . Otherwise you will end up with multiple applications with the same name and an appended language name due to the type of metrics and manner of reporting in different languages . There is no way to consolidate two applications of the same name written in different languages in your New Relic account . You could however create a custom dashboard which will allow you to place charts from multiple applications in one dashboard . Comment : Oh That means the official Elasticsearch plugin can t coexist with a java-agent as well No ES stats and JVM metrics at the same time Comment : They co-exist just fine . You simply cannot merge them into a single chart . Much as you cannot create for example a ruby application and a python application with the same name and expect them to occupy the same application space in New Relic . They will both report but under separate application instances in the New Relic Dashboard .", "Question : null .. .

Within the same WSGI application file you then need to add a wrapper around the actual WSGI application entry-point . If the WSGI application entry-point is a function declared in the file itself then you can use a decorator .

We do extensive testing and estimate our overhead impact to be roughly 5 + - a few points as it relates to CPU impact on the box and application response time . This is based on a number of different frameworks and load patterns we test with as well as our default instrumentation byte code probes . Given that the Server Monitors do much less instrumentation than our language agents and mostly just query data we would expect this number to be even lower . Since every application and server is different we always encourage customers to run their own tests in a pre-production environment to validate overhead and let us know if they encounter anything different . Based on our current traffic datacenter bandwidth divided by number of agents reporting we calculate each agent consumes an average of 0.0008 Mb s megabytes second 838 bytes second or roughly 50K bytes minute .

Often it is the case that a customer is using a backlevel version of the CVI Run-Time Engine RTE . When possible the customer is urged to upgrade to the latest but when they can t I must build the software targeting the older RTE . LabWindows does not support compiling for previous versions of the RTE so the work-around is to install multiple versions of the LabWindows Development Environment and compile using whichever matches the target RTE . How can one install multiple versions on the same machine .. . Answer : The LabWindows installer will not permit an older version to be installed on a machine which already has a newer version on it . To get around this the LabWindows Development Environment must always be installed in the order of oldest to newest with the oldest version installed first .

My customer s lab stations all have the CVI 9.0 runtime environment RTE installed . The customer strongly prefers to avoid updating their lab stations to the latest CVI RTE . I have installed the older version of LabWindows 9.0 on my machine and successfully built my project so I know that my code compiles under both environments . Ideally I would like to use LabWindows 2012 and just tell it to target the older CVI RTE . Is this possible .. . Answer : No this is not possible . Applications built-in LabWindows CVI are only compatible with the same version of the Run-Time Engine or later versions . Also note that up until CVI 2012 only one version of the Run-Time Engine can be installed on a system at a time . In CVI 2012 the side-by-side Run-Time Engine was introduced which allows for multiple versions to be installed on the same system and for applications to be bound to a specific version 2012 or later . You can however install multiple versions of the CVI environment on a system . This would allow you to develop in CVI 2012 but build in CVI 9.0 . You would need to pay particular attention that you do not use any features or library functions introduced in CVI 2012 or later . The user-interface UIR files can be saved for older versions using the Save As menu item . Additionally you would need to downgrade your project to the older version . Since CVI 9.0 and 2012 are pretty close in version this is likely not a major issue it might work without any problems . Comment : I have run into trouble installing both 2012 and 9.0 on the same machine . The installer for 9.0 tells me that it will not install because a more recent version already exists .

Supposedly it plays well with anything that fits the MS API MSSCC SCC but I haven t found this to be the case in practice . I d love if there was a SVN service that works well with it but I suppose that s asking for too much . .. . Answer : The way that you should set up your development should be as follows : .. . .. . Option 1 : Do your normal development in LabWindows CVI . For source control use Subversion and for your interface to Subversion use TortiseSVN . I have been using TortiseSVN with VS2008 and VS2005 for a while now and I find that it is just fine . Option 2 : Do your normal development in VS2005 or VS2008 and link-to the Measurement Studio libraries supplied by National Instruments . There you will have the option of using C C++ C or whatever your heart desires . You can also integrate other libraries or subsystems such as MatLab and you would get the added benefit of framing your questions in terms of Microsoft Technologies vs National Instruments technologies where the support is much smaller . You can integrate Subversion with Visual Studio through a number of addons http : ankhsvn.open.collab.net but again I prefer to use TortiseSVN .

The development-environment that comes with Labwindows CVI is pretty decent -- they have a drag-and-drop GUI building interface that makes it easy to position controls within windows and wire them up to your C code if that matters to you .

I have mostly used the MultiClientServer sample provided by NI as a model to implement a server that uses multi-threading .

I have used run-time variable assignments for regular ctrls never for tabs . Tab controls in LabWindows CVI are as you have discovered layer under the handle to the tab panel .

Because the data I am interesting in protecting is a struct I am unable to explicitly set nesting level so I assume that the nesting level stays at 0 i.e . that once a single thread safe pointer has been issued a request for second will be denied until the first has been released .

Execution continues through the DefineThreadSafeVar CLI SafeCli statement by continuing to use the F8 step-into key and subsequent requests for a pointer to the thread-safe variable are granted without ever having released the original . My expectations are that these macros should prevent access to a thread-safe variable once a pointer to it has been issued and not yet released . Are my expectations incorrect Or have I implemented the calls incorrectly Here is my source code : Comment : Is it possible that since you re calling func2 within the same thread it simply already has access to it Understanding you may have more code beyond this example you re not running multiple threads in this case . func2 is in the same call stack since it s being called inside func1 and hence the same thread . .. . Answer : In your case you are calling func2 within func1 and subsequently is within the same call stack and thus the same thread . You re granted access because you are requesting the pointer from within the same thread that already has access to the pointer . GetPointerToSafeCli is a waiting call . Had it been called from thread A and then again in thread B before ReleasePointerToSafeCli was called back in thread A thread B would wait until the pointer was released before granting access .

There are DaqMx python bindings http : www.scipy.org Cookbook Data Acquisition with PyUL too .", "Question : I m not sure how one layouts a GUI e.g . buttons edit boxes text and etc . when one is given measurements in pixels . As in Microsofts s GUI Guidelines all the specifics are given in distances of pixels . How does one transform that into actual distances when using another editor besides a Microsoft editor Thanks Comment : That completely depends on what kind of GUI . Comment : what makes no sense . Comment : What editor are you trying to use The quality of answer depends on that as the techniques for each are different . LabWindows CVI for example has extensive libraries specifically for controlling and scaling User Interface objects . .. . Answer : For LabWindows CVI : .. . .. . EDIT to correct function names : .. . .. . In the LabWindows CVI development-environment you can use a family of functions also accessible through function panels that provide status and control of panels and controls things such as position size color.. . et . al . called the User Interface Library . Functions such as GetCtrlAttribute SetCtrlAttribute GetPanelAttribute and SetPanelAttribute . Each of these uses an enumerated list of pre-defined arguments to access which of the many properties you would like to control . For example to set the size and position of a panel as it is displayed on the monitor you would use something like : .. . .. . There are many more attributes properties that can be set or retrieved using these four functions such as background-color whether panel control is active or greyed out frame color etc . As mentioned before there is a similar set of functions in the same family for controls Get Set CtrlAttribute that provide control for all the control properties .", "Question : I ve developed a software using National Instruments LabWindows CVI and installed the .exe in a Windows 7 32-bit PC with 4GB RAM .

I ve reviewed my software code many times and I am sure that I am not doing anything wrong in the software which causes this error to come up . Is this anything related to windows and how can I resolve this Help is much appreciated . Thanks Sujith Rajan Comment : Seems like you have a bug in your software . Test it and run it in a debugger . Or activate DrWatson and look at the DrWatson output . Comment : If I have a bug in my software I should see this issue coming at same place and same time I run the software . My software ran for 3 days without any issues and suddenly today I got this issue . Its very random . Your thoughts Comment : Not all bugs are consistently reproducible . Comment : @SujithRajan Welcome to software development and to the world of hard-to-find bugs which are not easily reproducible . .. . Answer : I have encountered similar problems several times . This may happen even with simple programs like a console-application used to get input from user and display some data on screen after processing it . Usually this is an indication that your computer is unable to provide enough resources to this program or that there is a bug in your code . It might be random due to the following reasons : .. . .. . 1 . The Processor might already be busy with several demanding tasks and your program needs to be closed due to this . At other times when it works well the resources might be available . 2 . Your program might have a certain logical error that appears at runtime only when certain conditions are fulfilled . such as an erroneous conditional statement .. . .. . 3 . Your program might have an infinite-loop . 4 . Windows suspects your file to be harmful to the system for some reason ." ] }

Answer : I don t know pylucene very well as I only work with the java version but as far as I know pylucene is accessing the java implementation . If this is the case you are missing the Version parameter in the constructor . As SnowballAnalyzer has been deprecated in lucene 3.1.0 I suggest you directly use the spanish analyzer .", "Question : I use SnowballPorterFilterFactory for index and query analyzers . When i search for profession word . Solr successfully finds only articles that contains profession but i want professional professionalism .. . This is the current configuration on schema.xml Comment : I would suggest going to the Solr admin panel clicking on Analysis and running a field analysis on this type . Do both the query and index ones and see whether they re getting stemmed the same way or not . Comment : Also look at the Solr logs and see if the Porter filter factory is being loaded correctly especially with the additional language tag or if it s throwing some kind of warning . .. . Answer : What is happening is porter is over-stemming your query . When you search for profession your keyword gets stemmed down to profess whereas profession professional and professionalism are all stored in the index as profession . The only real way you are going to get around this is by adding another fieldType where you do not stem your query . Something like : .. . .. . With a copyfield like : .. . .. . copyField source your text field dest text unstem query field Comment : I don t think this is the issue - I use the Porter stemmer myself and I ve never faced this double-stemming issue before . Comment : I ran his setup through the Solr analysis and this was the result I got . Profession gets stemmed down to profess and professional gets stemmed to profession in the index . They will not match with his current setup . That is why there is an analyzer type one for storing content in the index and one for how to compare when running a query . Comment : hi thank s for your response i verified my logs and used copyfield solution but the problem persiste please note that i use edismax query parser . should i add the on my q parameter example : profession Comment : If he doesn t stem the query it s not going to match what he has in the index . One dirty getaround however is to stem everything twice . That way everything will be the stemmed to the base . Comment : There is no problem about the stem but the problem is to combine the stem with the mark . so the Profession word is stemmed to profess and when i add mark after prefess they don t find the articles with profess profession professional.. .", "Question : null .. .

I tried it with walk walking walks like mentioned here http : wiki.apache.org solr AnalyzersTokenizersTokenFilters CharFilterFactories . Is maybe the combination of the filters the problem Comment : Shouldn t you try it with actual german words And be sure to look at the tokens and not the text returned from the field which will be identical to the stored one . Search for the stemmed version of a german word and see if that changes . Use the analysis page under the Solr Admin interface to see how the tokens are generated and the text is processed for the field . Comment : When you say can t get it to work what does that mean exactly How are you using the configured analyzers what outcome is it you expect and what happens instead Comment : Thanks for the help .

I would like to switch from searching with the StandardAnalyzer to the EnglishAnalyzer which will perform stemming of terms . The search results are good but now the highlighter doesn t always find a match . Here s an example of what I m looking at : .. . .. . Using the EnglishAnalyzer and searching for goat both documents are matched but the highlighter is only able to find a matched fragment from document 2 . Is there a way to have the highlighter return data for both documents I understand that the characters are different for the tokens but the same tokens are still there so it seems reasonable for it to just highlight whatever token is present at that location . If it helps this is using Lucene 3.5 . .. . Answer : I found a solution to this problem . I changed from using the Highlighter class to using the FastVectorHighlighter . It looks like I ll pick up some speed improvements too at the expense of storage of term vector data .

Everything seems to be working as expected except that non-Windows OS s don t kick off in my automated process . I have a bunch of OS X browsers configured on TestSwarm that seem to be configured correctly they just never get launched during the automated runs . I m able to join the swarm manually with BrowserStack where I manually pull up an OS X browser and browse to the join url on my TestSwarm instance and it will properly pick up the browser and start running tests against it . The testswarm-browserstack nodejs module just seems like its ignoring the OS X browsers when it requests browsers from BrowserStack .

I try to configure browserstack-cli . I can run the test from circleci via tunnel on Browserstack but never report back to circleci server . Could you please share your experience if you already played with this stack Thank you very much .. . Answer : The solution is to use BrowserStackLocal and browserstack-cli tools together . The 64bit linux version of BrowserStackLocal builds up the tunnel from circleCI server to Browserstack server .

This line is responsible for closing the Tunnel which in my case was to BrowserStack . I was able to get the runner to exit cleanly by simply changing from SIGINT to SIGTERM . The question is why doesn t it work with SIGINT According to wikipedia https : en.wikipedia.org wiki Unix signal SIGINT it s nearly identical to SIGTERM . The original question mentioned issues with BrowserStack for ref I m using v5.1 of the BrowserStackLocal https : www.browserstack.com browserstack-local BrowserStackLocal-darwin-x64.zip for OS X so in all likelihood there is still an issue here . But I could see no documentation on the binary . That said I noticed on the BrowserStack automate website that all the sessions are closed correctly and the runs are correctly labelled by Intern via the BrowserStack REST API as pass fail etc .

Answer : Axibase Time-Series Database http : axibase.com products axibase-time-series-database supports MIN VALUE TIME and MAX VALUE TIME aggregators . MIN VALUE TIME returns time in milliseconds when the MIN value was first reached within the period . MAX VALUE TIME returns time in milliseconds when the MAX value was first reached within the period . Multiple aggregators can be combined within the same API request so you can fetch both MAX and MAX VALUE TIME in one go . As for the back-end ATSD uses HBase for raw storage . Disclosure : I work for Axibase . Export Screenshot http : i.stack.imgur.com qKR7z.png .. . .. . UPDATE 1 : Examples on how these aggregators can be represented .

Posting the details in answer mode to include a screenshot and a description of these aggregators . .. . Answer : You can do this type of query in Cassandra 2.2 . The older 2.0 branch is outdated and has fewer query options than 2.2 . In 2.2 it looks like this : .. . .. . For some more background although CQL Cassandra Query Language looks similar to SQL it has a lot of restrictions on what types of queries you can do . See this http : www.datastax.com dev blog a-deep-look-to-the-cql-where-clause . So you have a few options : .. . .. . 1 . Set up your schema and queries to work within the restrictions of CQL sometimes relying on code in your client to do filtering analysis on a superset of the rows you are actually interested in . 2 . You can create UDF s User Defined Functions and user defined aggregate-functions to do some additional work on the query co-ordinator i.e . using in cluster resources instead of client resources . 3 . You can pair Cassandra with Apache Spark which can do much more complex analytics than CQL but is somewhat complex to set up and use . 4 . In Cassandra 3.0 there is a new feature called materialized-views which lets you define an alternate primary-key for your data to support different query patterns on your dataset than would be supported by the base table . Cassandra 3.0 is currently in beta release . Cassandra 2.2 adds the min max avg and sum functions to CQL along with user-defined-functions so is more powerful than 2.0 . I think over time CQL will slowly gain more SQL functionality but some traditional SQL operations are difficult in a distributed model and will take time to be implemented . Comment : I tried the above but as even your sample shows it returns the max value but not the corresponding sampletime . It selects the first sampletime that matches the range and the max value . Paaland 6 mins ago Comment : Interesting I didn t notice that before . I guess it s a bug or limitation . Then you re probably stuck with trying some of the other approaches I mentioned .", "Question : I have a development-machine that had a single-node Cassandra 2.1.2 setup .

I can see the files for my database under var cassandra data and would like to recover that data . Nothing outside of var survived -- no configs or binaries . Is it as simple as copying that directory to the var cassandra data directory on the good system or is there some other more detailed procedure for recovering importing that data .. . Answer : All you need to remember from your config files - is what was the partitioner . Now you should save your data files somewhere safe create another single-node cluster then follow the procedure described here http : www.datastax.com documentation cassandra-2.0 cassandra operations ops snapshot restore new cluster.html .

Is the consistency level of such a write always at QUORUM Would this mean that even if I have a multi data center setup with 100s of nodes then quorum of the entire cluster majority of the row s replicas across all data centers is involved Won t this be really slow and wont it affect availability Can we do LOCAL QUORUM or EACH QUORUM consistency This would be preferred if writers for data replicated across multiple data centers would always originate from a specific data center only . .. . Answer : The suggested Consistency Level for lightweight transactions is SERIAL . Behind the scenes however SERIAL is even worse than QUORUM because it s a multi-phase QUORUM . As you said the situation can get hard to handle when you have multiple DC -- Datastax estimate effectively a degradation to one-third of normal .

Also using netstat I can see that the new server successfully establishes a tcp connection to port 7001 of the original server . Edit : .. . .. . Okay next day . I ve upgraded to java 1.7.0 60 on both machines . Gossip now works with internode encryption : none . I very much doubt the new result is related to the change in JDK it s more likely related to some carelessness in scrubbing directories or the like . I ve commented the line in each config file that lists ciphers . Gossip still fails in the same way with internode encryption : all . The seed node s logs are clean but the other node logs Filtering out TLS RSA WITH AES 256 CBC SHA TLS DHE RSA WITH AES 256 CBC SHA TLS ECDHE RSA WITH AES 256 CBC SHA as it isnt supported by the socket repeatedly until gossip fails . I think the log entry is related to the failure . Why one logs this and the other not I don t know . They re both debian running the same jdk version . Edit : .. . .. .

According to my knowledge Cassandra will create two hidden column families like so : .. . .. . Cassandra secondary indexes are implemented as local indexes rather than being distributed like normal tables . Each node only stores an index for the data it stores . Consider the following query : .. . .. . 1 . How will this query execute under the hood in Cassandra 2 . How will a high-cardinality column index record link id affect its performance 3 . Will Cassandra will touch all nodes for the above query Why .. . 4 . Which criteria will be executed first base table partition key or secondary index partition key How will Cassandra intersect these two results Comment : My 2 cents : Since you specified a full partition key it makes no sense to query all the nodes . It should clearly only query a node responsible for 35 78005 . Due to the way Cassandra is designed I m expecting it to consider reducing the number of involved nodes as a priority . Given that the only involved node should probably look at how many records it has for 35 78005 and how many it has in the index for record link id 9897 and use the fastest one to serve the query which isn t necessarily the smallest one depending on whether the index is also sorted by primary-key . Comment : My theory seems to be supported by docs.datastax.com en cql 3.0 cql ddl http : docs.datastax.com en cql 3.0 cql ddl ddl using multiple indexes.html Comment : if this the way then creating index over high-cardinality columns will be the fastest and best data model if you are including partition key also in criteria . .. . Answer : Query with only secondary index is also possible in Cassandra 2.x .. . .. . select from update audit where record link id 9897 .. . .. . But this has a large impact on fetching data because it reads all partitions on distributed environment . The data fetched by this query is also not consistent and could not relay on it .

But it also has an option of CL ANY .. . Answer : ANY will give you the fastest write performance if you don t care about possible loss but you can easily overload your nodes with it such that you cause extra loss .

Column 2 is a flag so values are repeating . I get the following error : .. . .. . So what is the right way to do it I really need to get the data that already filtered . Thanks . .. . Answer : So to make sure I understand your schema you have defined a table T1 : .. . .. . Correct If this is the case then Cassandra cannot find the data to answer your CQL query : .. . .. . because your query has not provided a value for column 1 without which Cassandra cannot compute the partition key which requires per your composite PRIMARY KEY definition both columns 1 and 2 and without that it cannot determine where to look on which nodes in the ring . By including 2 in your partition key you are telling Cassandra that that data is required for determine where to store and thus where to read that data . For example given your schema this query should work : .. . .. . since you are providing both values of your partition key . @Caleb Rockcliffe has good advice though regarding the need for other secondary supplemental lookup mechanisms if the above table definition is a big part of your workload . You may need to find some way to first lookup the values for 1 and 2 then issue your query . E.g . : .. . .. . Given a value for 1 the above will provide all of the possible 2 values through which you can then iterate : .. . .. . And then for each 1 and 2 combination you can then issue your query against table T1 : .. . .. . Hope this helps Comment : This helps a lot thank you . So does it mean that for the T1 index I need to do separate insert each time I insert to T1 Comment : Yes unfortunately . Cassandra likes denormalization which effectively means duplication . And it does not support foreign key constraints or things of that sort so your application code needs to know to write to the multiple relevant tables and to read from them . Comment : I just spent some time trying this and that in my schema and it seems I found a solution for my task based on what you ve shown . So we can say that for each specific select query I need to create a separate table and include that table in inserting batch in my code and that s fine as soon as these inserts are negligible rare right So Cassandra is for huge amount of reads and occasional inserts or updates right Again I am new in it and completely RDBMS guy Is there any mechanism inside Cassandra to keep all that tables updated instead of having multiples inserts in my code Comment : Actually Cassandra is optimized for writes it s the reads which are expensive . That s why the denormalization duplication is useful it helps improve Cassandra read latency . And no as far as I know there s nothing built into Cassandra to automatically keep related tables updated based on a single write insert . A large part of Cassandra s speed and scaling abilities come from not having that sort of schema relationships enforced by the database those relationships are treated as business or application logic and left to your application to handle .

My intention was to send a number of reads at a rate that is higher than the capacity of my backend servers thereby overwhelming them and resulting in server-side queuing . To do so I m using the datastax java driver cql version 2 to run my operations asynchronously in other words the calling thread doesn t block waiting for a response . The problem is that I m unable to reach a high-enough sending-rate to overload my backend servers . The of requests that I m sending is being somehow throttled by Cassandra . To confirm this I ve ran clients from two different machines simultaneously and the total number of requests sent per unit time is still peaking at the same value . I m wondering if there s a mechanism that is employed by Cassandra to throttle the amount of requests that are being received Otherwise what else might be causing this behavior .. . Answer : Each request received by Cassandra will be handled by multiple thread pools implementing a staged event-driven architecture https : en.wikipedia.org wiki Staged event-driven architecture where requests will be queued for each stage . You can use nodetool tpstats http : docs.datastax.com en cassandra-2.0 cassandra tools toolsTPstats.html to inspect the current status of each queue . Once too many requests are about to overwhelm the server Cassandra will shed load by dropping requests once queues are about to reach their capacity . You ll notice this by numbers shown in the dropped section of tpstats . In case no requests are dropped all of them will eventually complete but you may see higher latencies using nodetool cfhistograms http : docs.datastax.com en cassandra-2.0 cassandra tools toolsCFhisto.html or WriteTimeoutExceptions on the client . Comment : I ve checked the codebase for Cassandra s threadpoolexecutor and my understanding is that the workqueue is practically unbounded i.e . the maximum size is by default set to an arbitrarily high value . However even assuming that this is not true tpstats reports 0 blocked dropped operations . Comment : It s also important to note that the java driver client I m utilizing is not timing out on any requests and that Cassandra s queues aren t exploding i.e . they keep fluctuating between 0 and 300 . However despite all this I can t manage to exceed a certain sending rate in my experiments .", "Question : Say I have a 50 node-cluster and my replication factor 3 and Write Consistency Level Quorum which is 50 2 + 1 26 and Read Consistency Level ONE .

For example in an old school menu you might have : .. . .. . thereby controlling the flow of user interaction . In a GUI program or somesuch instead we say .. . .. . So now control is inverted.. . instead of the computer accepting user input in a fixed order the user-controls the order in which the data is entered and when the data is saved in the database . Basically anything with an event-loop callbacks or execute triggers falls into this category . Comment : dont mark this guy down . technically he is correct martinfowler.com bliki InversionOfControl.html http : martinfowler.com bliki InversionOfControl.html IoC is a very general principal . Flow of control is inverted by dependency-injection because you have effectively delegated dependancies to some external system e.g . IoC container Comment : Agreed with Schneider s comment . 5 downvotes The mind boggles since this is the only answer that s really correct . Note the opening : like a gui program . Dependency injection is only the most commonly-seen realization of IoC . Comment : Indeed this is one of the few correct anwsers Guys IoC is not fundamentally about dependencies . Not at all . Comment : +1 - This is a good description with example of the following statement by Martin Fowler - Early user interfaces were controlled by the application program . You would have a sequence of commands like Enter name enter address your program would drive the prompts and pick up a response to each one . With graphical or even screen based UIs the UI framework would contain this main loop and your program instead provided event handlers for the various fields on the screen . The main control of the program was inverted moved away from you to the framework .

Answer : IoC - Inversion of control is generic term independent of language it is actually not create the objects but describe in which fashion object is being created . DI - Dependency Injection is concrete term in which we provide dependencies of the object at run time by using different injection techniques viz . Setter Injection Constructor Injection or by Interface Injection .", "Question : I see a lot of IoC frameworks for .Net and Java . Does anyone know why there are no equivalent frameworks for Smalltalk . This is more a philosophy question than anything else . I m wondering if there is something in the Smalltalk way of doing things that precludes the necessity of having an IoC framework . Comment : Great question .. . Answer : A few possible reasons for this . One is that we haven t bothered to use the IoC qualifier which is essentially redundant - since calling something a framework implies the inversion-of-control flow . Another is that the Smalltalk language provides direct support for IoC flows - in the form of closures . One result-of programming with closures is that the flow of control as found in frameworks doesn t seem so starkly different as to evoke a sense of being inverted from a normal sense of flow rather with closures the flow of control is flipping back and forth between these two perspectives all of the time and everywhere . Even within single statements . A third reason perhaps is that even without closures the inversion-of-control being described is not uniquely associated with frameworks - the same flows are found in most forms of code that involve I O . Fourth Smalltalkers probably use these sorts of flows even more than others as we lean more heavily on the notions of objects and the messages sent between them than on the notions of structures and the calling of member-functions . In the absense of closures these two views are equivalent and interchangeable but the addition of closures changes the result - the sense of control-flow in use is one of the effects . Finally one might even think about describing the REPL style of control-flow as a simpler but inverted sense of the normal flow normal in the sense that it is used nearly everywhere else . In summary the same sorts of frameworks exist for Smalltalk . We describe them a bit differently is all . The difference is at least in part due to the presence and utilization of closures in Smalltalk which many other environments do not yet provide -- -- notably C++ C and Java .", "Question : Inversion of Control or IoC can be quite confusing when it is first encountered . 1 .

Answer : Inversion of Control is a generic principle while Dependency Injection realises this principle as a design pattern for object graph construction i.e . configuration controls how the objects are referencing each other rather than the object itself controlling how to get the reference to another object . Looking at Inversion of Control as a design pattern we need to look at what we are inverting . Dependency Injection inverts control of constructing a graph of objects . If told in layman s term inversion-of-control implies change in flow of control in the program . Eg . In traditional standalone app we have main method from where the control gets passed to other third party libraries in case we have used third party library s-function but through inversion-of-control control gets transferred from third party library code to our code as we are taking the service of third party library . But there are other aspects that need to be inverted within a program - e.g . invocation of methods and threads to execute the code . For those interested in more depth on Inversion of Control a paper has been published outlining a more complete picture of Inversion of Control as a design pattern OfficeFloor : using office patterns to improve software-design http : doi.acm.org 10.1145 2739011.2739013 with a free copy available to download from http : www.officefloor.net mission.html .. . .. .

Answer : I shall write down my simple understanding of this two terms : .. . .. . Dependency Injection DI : .. . Dependency injection generally means passing an object on which method depends as a parameter to a method rather than having the method create the dependent object . What it means in practice is that the method does not depends directly on a particular implementation any implementation that meets the requirements can be passed as a parameter . With this objects tell thier dependencies . And spring makes it available . This leads to loosely coupled application development . .. . .. . Inversion of Control IoC Container : .. . This is common characteristic of frameworks IOC manages java objects .. . from instantiation to destruction through its BeanFactory . -Java components that are instantiated by the IoC container are called beans and the IoC container manages a bean s scope lifecycle events and any AOP features for which it has been configured and coded . QUICK EXAMPLE : Inversion of Control is about getting freedom more flexibility and less dependency . When you are using a desktop computer you are slaved or say controlled . You have to sit before a screen and look at it . Using keyboard to type and using mouse to navigate . And a bad written software can slave you even more . If you replaced your desktop with a laptop then you somewhat inverted control . You can easily take it and move around . So now you can control where you are with your computer instead of computer controlling it . By implementing Inversion of Control a software object consumer get more controls options over the software objects instead of being controlled or having less options . Inversion of control as a design guideline serves the following purposes : .. . .. . .. . There is a decoupling of the execution of a certain task from implementation . Every module can focus on what it is designed for . Modules make no assumptions about what other systems do but rely on their contracts . Replacing modules has no side effect on other modules .. .

Answer : Is IoC a direct implementation of the Dependency Inversion Principle The two are related in a way that they talk about abstractions but that s about it . Inversion of Control is : .. . .. . a design in which custom-written portions of a computer program receive the flow of control from a generic reusable library source https : en.wikipedia.org wiki Inversion of control .. . .. . Inversion of control is allowing us to hook our custom code into the pipeline of a reusable library . In other words Inversion control is about frameworks . A reusable library that does not apply Inversion of Control is merely a library . A framework is a reusable library that does apply Inversion of Control . Do note that we as developers can only apply Inversion of Control if we are writing a framework ourselves you can t apply inversion-of-control as an application developer . We can and should however apply Dependency Inversion Principle and the Dependency Injection pattern . Does IoC always break encapsulation and therefore OOP Since IoC is just about hooking into the pipeline of a framework there is nothing that s leaking here . So the real question is : does Dependency Injection break encapsulation . The answer to that question is : no it does not . It doesn t break encapsulation because of two reasons : .. . .. . Since the Dependency Inversion Principles states that we should program against an abstraction a consumer will not be able to access the internals of the used implementation and that implementation will therefore not be breaking encapsulation to the client . The implementation might not even be known or accessible at compile-time because it lives in an unreferenced assembly and the implementation can in that case not leak implementation details and break encapsulation . Although the implementation accepts the dependencies it requires throughout its constructor those dependencies will typically be stored in private fields and can t be accessed by anyone even if a consumer depends directly on the concrete type and it will therefore not break encapsulation . Should IoC be used sparingly religiously or appropriately Again the question is Should DIP and DI be used sparingly . In my opinion the answer is : NO you should actually use it throughout the application . Obviously you should never apply things religiously . You should apply SOLID principles and the DIP is a crucial part of those principles . They will make your application more flexible and more maintainable and in most scenarios it is very appropriate to apply the SOLID principles . What is the difference between IoC and an IoC container Dependency Injection is a pattern that can be applied either with or without a IoC container . An IoC container is merely a tool that can help building your object graph in a more convenient way in case you have an application that applies the SOLID principles correctly . If you have an application that doesn t apply the SOLID principles you will have a hard time using a IoC container . You will have a hard time applying Dependency Injection . Or let me put it more broadly you will have a hard time maintaining your application anyway . But in no way an IoC container is a required tool . I m developing and maintaining an IoC container for .NET but I don t always use a container for all my applications . For the big BLOBAs boring line of business applications I often use a container but for smaller apps or windows-services I don t always use a container . But I do almost always use Dependency Injection as a pattern because this is the most effective way to adhere to DIP . Note : Since an IoC container helps us in applying the Dependency Injection pattern IoC container is a terrible name for such library . .. . .. .

My Question : What s exactly is IOC and DI I am confused . Based on pococapsule IOC is something more significant than just invert the control of objects or between programmers and frameworks . Comment : Here s a good writeup on the subject IoC vs DI Dependency Inject vs SL Service Locator : tinyurl.com kk4be58 http : tinyurl.com kk4be58 - Extract from the url : IoC vs DI Dependency Injection IoC is the general concept where control of flow is Inverted from client code to framework which Does something for the client . SL Service Locator and DI Dependency Injection are two design-patterns stem off from IoC . .. . Answer : IoC is a generic term meaning rather than having the application call the methods in a framework the framework calls implementations provided by the application . DI is a form of IoC where implementations are passed into an object through constructors setters service look-ups which the object will depend on in order to behave correctly . IoC without using DI for example would be the Template pattern because the implementation can only be changed through sub-classing . DI Frameworks are designed to make use of DI and can define interfaces or Annotations in Java to make it easy to pass in implementations . IoC Containers are DI frameworks that can work outside of the programming language . In some you can configure which implementations to use in metadata files e.g . XML which are less invasive . With some you can do IoC that would normally be impossible like inject implementation at pointcuts http : en.wikipedia.org wiki Pointcut . See also http : martinfowler.com articles injection.html InversionOfControl Comment : Thanks for the answer . But the other paper suggests that with IOC IOC containers are far more superior to EJB while Martin Fowler suggests that EJB is a typical example of IOC . Comment : EJB management is really a typical example of IoC . You can see it from the fact that the lifecycle of a EJB is managed by the container not by the programmer . The programmer does not create or destroy an EJB instance because the control is delegated to the server . That is the concept of IoC : the external code controls when your code is called which is usually the inverse of what its done most of the time . Comment : IoC is a generic term meaning rather than having the application call the methods in a framework the framework calls implementations provided by the application . Can you explain a it more about this Comment : Aka Hollywood principle http : en.wikipedia.org wiki Hollywood principle don t call us we ll call you . Leaves the invocation up to the framework rather than the application .

Answer : To understanding the concept Inversion of Control IoC or Dependency Inversion Principle DIP involves two activities : abstraction and inversion .

What is it It is a practice where you let the actual behavior come from outside of the boundary Class in Object Oriented Programming . The boundary entity only knows the abstraction e.g interface abstract-class delegate in Object Oriented Programming of it . 2 . What problems does it solve In term of programming IoC try to solve monolithic code by making it modular decoupling various parts of it and make it unit-testable . 3 .

Answer : IoC is about inverting the relationship between your code and third-party code library framework : .. . .. . In normal s w development you write the main method and call library methods . You are in control : .. . In IoC the framework controls main and calls your methods . The Framework is in control : .. . .. . DI Dependency Injection is about how the control flows in the application . Traditional desktop application had control-flow from your application main method to other library method calls but with DI control-flow is inverted that s framework takes care of starting your app initializing it and invoking your methods whenever required . In the end you always win : Comment : This is a good explanation because it is uses plain language and little jargon .", "Question : I was recently having a debate about the Dependency Inversion Principle Inversion of Control and Dependency Injection . In relation to this topic we were debating whether these principles violate one of the pillars of OOP namely Encapsulation . My understanding of these things is : .. . .. . The Dependency Inversion Principle implies that objects should depend upon abstractions not concretions - this is the fundamental principle upon which the Inversion of Control pattern and Dependency Injection are implemented . Inversion of Control is a pattern implementation of the Dependency Inversion Principle where abstract dependencies replace concrete dependencies allowing concretions of the dependency to be specified outside of the object . Dependency Injection is a design pattern that implements Inversion of Control and provides dependency-resolution . Injection occurs when a dependency is passed to a dependent component . In essence the Dependency Injection pattern provides a mechanism for coupling dependency abstractions with concrete implementations . Encapsulation is the process whereby data and functionality that is required by a higher level object is insulated away and inaccessible thus the programmer is unaware of how an object is implemented . The debate got to a sticking point with the following statement : .. . .. . IoC isn t OOP because it breaks Encapsulation .. . .. . Personally I think that the Dependency Inversion Principle and the Inversion of Control pattern should be observed religiously by all OOP developers - and I live by the following quote : .. . .. . If there is potentially more than one way to skin a cat then do not behave like there is only one . Example 1 : .. . .. . Here we see an example of encapsulation . The programmer only has to call Main and the cat will be skinned but what if he wanted to skin the cat with say a set of razor sharp teeth Example 2 : .. . .. . Here we observe the Dependency Inversion Principle and Inversion of Control since an abstract ICatSkinner is provided in order to allow concrete dependencies to be passed in by the programmer . At last there is more than one way to skin a cat .. . .. . The quarrel here is does this break encapsulation technically one could argue that .SkinTheCat is still encapsulated away within the Main method call so the programmer is unaware of the behavior of this method so I do not think this breaks encapsulation . Delving a little deeper I think that IoC containers break OOP because they use reflection but I am not convinced that IoC breaks OOP nor am I convinced that IoC breaks encapsulation . In fact I d go as far as to say that : .. . .. . Encapsulation and Inversion of Control coincide with each other happily allowing programmers to pass in only the concretions of a dependency whilst hiding away the overall implementation via encapsulation . Questions : .. . .. . Is IoC a direct implementation of the Dependency Inversion Principle Does IoC always break encapsulation and therefore OOP Should IoC be used sparingly religiously or appropriately What is the difference between IoC and an IoC container Comment : Being a question about conceptual questions about software development you might have more luck getting this answered on programmers.stackexchange.com http : programmers.stackexchange.com . As written this is a request for discussion which isn t the forte of a Q A site like SO . Comment : Poor kitty .

Answer : Encapsulation does not contradict with Dependency Inversion Principles in Object-Oriented Programming world . For example in a car design you will have an internal engine which will be encapsulated from outside world and also wheels that can be replaced easily and considered as outside component of the car . The car has specification interface to rotate the shaft of the wheels and the wheels component implements part that interact with the shaft . Here The internal engine represents the encapsulation process while the wheel components represent the Dependency Inversion Principles DIP in the car design . With DIP basically we prevent building a monolithic object and instead we make our object composable . Can you image you build a car where you cannot replace the wheels because they are built-in into the car .

Answer : Inversion of Control is about getting freedom You get married you lost freedom and you are being controlled . You divorced you have just implemented Inversion of Control . That s what we called decoupled . Good computer system discourage any very close relationship . more flexibility The kitchen in your office only serves clean tap water that is your only choice when you want to drink . Your boss implemented Inversion of Control by setting up a new coffee machine . Now you get the flexibility of choosing either tap water or coffee . and less dependency Your partner has a job you don t have a job you financially depend on your partner so you are controlled . You find a job you have implemented Inversion of Control . Good computer system encourage in-dependency . When you use a desktop computer you are slaved or say controlled . You have to sit before a screen and look at it . Using keyboard to type and using mouse to navigate . And a bad written software can slave you even more . If you replace your desktop with a laptop then you somewhat inverted control . You can easily take it and move around . So now you can control where you are with your computer instead of your computer controlling it . By implementing Inversion of Control a software object consumer get more controls options over the software objects instead of being controlled or having less options .", "Question : Inversion of Control or IoC can be quite confusing when it is first encountered . 1 .

Answer : For example task 1 is to create object . Without IOC concept task 1 is supposed to be done by Programmer.But With IOC concept task 1 would be done by container . In short Control gets inverted from Programmer to container . So it is called as inversion-of-control . I found one good example here http : www.goospoos.com 2009 12 inversion-of-control-basics-with-example . Comment : What is a container Comment : A container is a concept in IoC where the object-model including dependencies relationships between user object and used object and object instances reside and is managed -- e.g . contained . The container is usually provided by a IoC framework such as Spring . Think of it as a runtime repository for the objects that make up your application ." ] }

My question is this : Is there anyway for me to construct the --regex-puppet argument or --regex- LANG lines generally to collect information about a tag s scope To perhaps declare that tags meeting criterion A are always going to be scope-parents of tags meeting criterion B man ctags suggests no clear way to add arbitrary scope information but I might be overlooking another solution snipped slightly for emphasis : .. . Answer : No unfortunately that is not possible with the regex pattern support in ctags . The only way to get ctags to generate correct scopes is to write a parser as an additional module in C . I would like to add support for a better handling of new languages to ctags if I find the time but so far that hasn t worked out and I m also still unsure about the best approach . If you re mostly interested in Tagbar support there is another approach though : Tagbar supports arbitrary tag-generating programs as long as their output is compatible to the ctags one so you could write a simple parser in say Python and configure Tagbar to use that .

I d post comparison images but I don t think its going to let me as a new member . As per romainl s suggestion I can set the vim filetype to scheme and it does work . This however only seems like an 80 solution when the documentation according to the extending pages seems to suggest that what I have should work . Perhaps I should be looking at filing a bug report . Thanks again Comment : Do your settings work when you use ctags directly from the command-line If not it s not a problem with TagList or Vim but with your regular expression . Comment : Does this --langmap scheme : .rkt work when ctags is used directly Comment : try tagbar looks better than taglist Comment : @locojay Indeed it does but it does not as far as I can see display the tags of multiple buffers at once .

Answer : Here is a small racket snippet I lifted from the official documentation http : docs.racket-lang.org quick index.html and saved as tt.rkt : .. . .. . Without racket-specific syntax indent files nothing is shown whether ft is set to racket of course or nothing the default . If I : set ft scheme both TagList and TagBar http : www.vim.org scripts script.php script id 3465 list checker as function . From left to right : the file TagBar TagList . TagList and TagBar against a racket file http : i.stack.imgur.com yEaIr.png .. . .. . From what I understand Racket is a rebranding of some Scheme derivative . If it doesn t deviate too much from the norm adding this line in your .vimrc may help : Comment : Thanks for answering . I d not actually found TagBar and interestingly enough it just worked with my .ctags file which I added to as I tested it . Unfortunately while it does work it doesn t display tags from multiple buffers at once at least I didn t see an option for it . I d like to see if I can get the problem fixed but it is good to know I can work around it . Thanks . Comment : No TagBar doesn t show tags for multiple buffers you can still use native commands like : tselect though . It s not as pretty and convenient but it works .", "Question : I ve recently started using racket and one of the first things I ve done has been to try and get the vim TagList plugin http : vim-taglist.sourceforge.net to work with it . However it doesn t work in the slightest . I can open racket files and the TagList window will be as blank as-if I had opened a text file . According to the extending page http : vim-taglist.sourceforge.net extend.html I have added the following to my .vimrc file : .. . .. . The extra ctags stuff is also in my .ctags file but TList was spitting out errors about my setting line not being any good .

If anyone else has any ideas on how to get it working then I would be extremely grateful . Thanks .. . .. . I d post a link-to the ctags one page as well but it wont let me new user .

The URIs are not equivalent because one has no query component while the other one has an empty query component . .. . .. . The URI standard STD 66 http : tools.ietf.org html std66 is currently RFC 3986 http : tools.ietf.org html rfc3986 . Section 6.2 . Comparison Ladder http : tools.ietf.org html rfc3986 section-6.2 describes methods how to test if URIs are possibly equivalent . In 6.2.3 . Scheme-Based Normalization http : tools.ietf.org html rfc3986 section-6.2.3 it says : .. . .. . Normalization should not remove delimiters when their associated component is empty unless licensed to do so by the scheme specification . For example the URI http : example.com cannot be assumed to be equivalent to any of the examples above . Where examples above refers to : .. . .. . .. . http : example.com .. . http : example.com .. . http : example.com : .. . http : example.com : 80 .. . .. . .. . These 4 URIs are equivalent . So http : example.com api item.json has no query component while http : example.com api item.json has an empty query component ." ] }

How might I restructure the test to read the same to the reader of the test and function the way I intend it to It s fine if the restructure means I can t use the standard RSpec format and have to require RSpec components differently the posts online didn t seem to follow the simple basic RSpec format . I think my code is fairly straighforward to interpret . In case not the intent is to use the CSV input to dynamically build the test . Each CSV row is a scenario that has multiple tests - 1 test differs based on a CSV field value hence the ifs the remaining tests are common to all scenarios . And we repeat this set for as many CSV scenario rows there are in the file . And the before all block is the global setup before we process the CSV data . In the restructure ideally I d like to keep the describe it text description blocks or some equivalent to them so that in the test results they show up describing the tests not just a bunch of expects . .. . Answer : Something like this should work : .. . .. . Notable changes from your version : .. . .. . No need to require rspec RSpec will load itself when you run the rspec command . I moved the CSV logic out of before : all and into the describe body . The problem with what you had before is that before hooks are run after all examples and groups are defined just before executing a particular group . You need to leverage the CSV file contents during spec definition time during which the describe block is executed . I switched from instance-variables to local-variables . What you had before didn t work because the before : all hook runs in the context of an instance of the example group class where as the describe block runs in the context of the class itself -- so they run in different contexts and don t have access to the same instance-variables . Once we move the logic into the describe block you can just use simple local-variables . I added clients to the last line of your before : all logic . What you had before was throwing away the result-of device client.map .. . but I m assuming that s what you want to use .

Using allow to set up message expectations with parameters that return test doubles and then using expect to make an assertion on the returned test doubles .. . Just using expect to set up the expectation with parameters and return the test double .. . .. . or is it all just semantics I know that providing specifying a return-value with expect was the syntax in RSpec mocks 2.13 https : www.relishapp.com rspec rspec-mocks v 2-13 docs message-expectations expect-a-message provide-a-return-value but as far as I can see the syntax changed in RSpec mocks 3 http : www.relishapp.com rspec rspec-mocks v 3-1 docs configuring-responses returning-a-value specify-a-return-value to use allow . However in the passing sample code below using either allow expect or just expect and return seems to generate the same result . If one syntax was favoured over another perhaps I would have expected there to be some kind of deprecation notice but since there isn t it would seem that both syntaxes are considered valid : .. . .. . If I deliberately make the tests fail by changing the passed-in baz parameter in the expectation to a different test double the errors are pretty much the same : .. . .. . So are there any real differences between these two tests either in result or expressed intent or is it just semantics and or personal preference Should allow expect be used over expect and return in general as it seems like it s the replacement syntax or are each of them meant to be used in specific test scenarios Update .. . .. . After reading Mori s answer http : stackoverflow.com a 28007007 567863 s I commented out the Foo.bar baz .qux line from the example code above and got the following errors : .. . .. . The allow spec fails because the foobar result double never gets to stand in for the result-of Foo.bar baz and hence never has qux called on it .. . The expect spec fails at the point of Foo never receiving .bar baz so we don t even get to the point of interrogating the foobar result double .. . .. . Makes sense : it s not just a syntax change and that expect and return does have a purpose different to allow expect . I really should have checked the most obvious place : the RSpec Mocks README https : github.com rspec rspec-mocks blob master README.md specifically the following sections : .. . .. . Mock Objects and Test Stubs https : github.com rspec rspec-mocks blob master README.md mock-objects-and-test-stubs .. . Test-Specific Extension https : github.com rspec rspec-mocks blob master README.md test-specific-extension .. . Setting Responses https : github.com rspec rspec-mocks blob master README.md setting-responses .. . Answer : See the classic article Mocks Aren t Stubs http : martinfowler.com articles mocksArentStubs.html . allow makes a stub while expect makes a mock . That is allow allows an object to return X instead of whatever it would return unstubbed and expect is an allow plus an expectation of some state or event . When you write .. . .. . .. . you re telling the spec environment to modify Foo to return foobar result when it receives : bar with baz . But when you write .. . .. . .. . you re doing the same plus telling the spec to fail unless Foo receives : bar with baz . To see the difference try both in examples where Foo does not receive : bar with baz .", "Question : I have several RSpec examples that share the following complex expectation with the array records and the floating-point numbers min long max long min lat max lat varying between these examples .

This works fine but now I have to call that method with e.g . in my examples . This looks foreign in RSpec s specification DSL . I d prefer to be able to write .. . .. . or .. . .. . instead . .. . .. . Is there a recommended way to achieve this I don t think I can use RSpec s matcher aliasing facilities for this as they only seem to map matcher names onto other matcher names not complete matcher invocations with arguments . Though maybe the options argument of alias matcher http : rspec.info documentation 3.2 rspec-expectations RSpec Matchers.html alias matcher-class method is meant for that Off course I could also implement a custom matcher but then I probably would be forced to provide an implementation that returns a boolean which contradict it being composed from already existing matchers . Not that it d be hard but I like the implementation using stuff like all and be between . Lastly I could also monkey-patch the class of the element of valid records to have a in bbox min long max long min lat max lat attribute so that RSpec would automatically provide the corresponding be in bbox min long max long min lat max lat matcher . .. . Answer : Sure you can do that . Make it a helper method https : www.relishapp.com rspec rspec-core v 3-2 docs helper-methods arbitrary-helper-methods . Helper Methods .. . .. . These are just normal Ruby methods . You can define them in any example group . These helper methods are exposed to examples in the group in which they are defined and groups nested within that group but not parent or sibling groups . I suggest putting that method in a helpfully named file stored in spec support . Possibly something such as spec support rgeo matchers.rb . As written this will define the helper on main mixing it into Kernel which makes it available to every object in Ruby . You ll need to make sure this helper file is required in all the necessary spec files with : require support rgeo matchers . Instead of defining helpers on main I suggest placing them in a module https : www.relishapp.com rspec rspec-core v 3-2 docs helper-methods define-helper-methods-in-a-module to prevent global leakage : .. . .. . Since the matcher is in a module you ll need to add include MyProject : : RGeo : : Matchers inside your RSpec.describe block . An alternative is to make it a shared context https : www.relishapp.com rspec rspec-core v 3-2 docs example-groups shared-context : .. . .. . With a shared context you ll need to use include context in-place of include : include context RGeo matchers . Complex Matchers .. . .. . While the matcher you describe is rather nested-if it fits your domain models and describes a coherent unit then that s acceptable in my book . The test one thing does not necessarily mean test only a single attribute . It means test a coherent concept or unit . What that means depends on the domain-model . Combining composable matchers http : www.relishapp.com rspec rspec-expectations v 3-2 docs composing-matchers with compound expectations http : www.relishapp.com rspec rspec-expectations v 3-2 docs compound-expectations as you have demonstrated provide an simple and valid alternative to writing a custom matcher http : www.relishapp.com rspec rspec-expectations v 3-2 docs custom-matchers . Alternatives .. . .. . Per your suggestion perhaps remove the all from the helper so that the matcher only describes being in a bounding-box : .. . .. . This makes the matcher more re-usable . As it really describe one thing e.g . inside a bounding-box .

Anybody please help me on this . Thanks", "Question : Is there anything like ondelete event handler or way to warn user before they want to clear the indexedDB database . Background : There is a offline first app that works by saving most of the data on indexedDB while offline . Now when the user goes online it tries to sync the data to the server but now if someone mistakenly resets browser or clears the indexedDB they might create a disaster since they have important data that needs to sync to server . So is there any way to overcome this problem Is there a way to save indexedDB as a persistent file system or disable deletion or raise an event and handle properly when there is a deletion .. . Answer : No . Despite how some of us are using it there is no guarantee that data in an IndexedDB database will remain there . This is by design it is temporary storage . The browser can free up space if it needs to . The situation will be somewhat improved when eventually it is possible to store IndexedDB data as persistent data http : code.google.com p chromium issues detail id 340350 but there s never going to be a way to guarantee data isn t deleted . IMHO the user should have the ability to delete data on their computer and it would be a significant problem if that wasn t true . And the problem may be even worse than you realize . For instance here s a bug in Chrome https : code.google.com p chromium issues detail id 340821 and maybe in other browsers too . If the user says delete my cookies and site data from the past 24 hours Chrome will completely delete any IndexedDB database that has been changed in the past 24 hours . So if you have 5000 objects in a DB that were created a year ago but never changed since and one that was edited today they all get deleted . This can be confusing for users but to my knowledge nobody has proposed a good solution . The only workaround is to sync to the server which obviously is not 100 reliable . So if you have any data that is super important it probably shouldn t be in a website s IndexedDB database except as a cache .", "Question : I ve been playing with IndexedDB in Firefox Ubuntu .. . .. .

Is there any way to do that If so Pls help me. . thank you. . .. . Answer : From what I understand in your question you are just using indexeddb like a cache layer in case the db goes done . What I would do is the following . In case you are working online a save of your data should exist out af 2 actions . Saving to your service SQL server and save to your indexeddb . In case-when you are offline I would do 2 operation . On is still updating your indexeddb but I would add an extra object store where you save all of your operation that have to be preformed on your service . Once back online you can processes them one by one . Comment : I am using IndexedDB to populate first time from SQL Server and save it in my indexedDB.. . Datas in my SQL Server wont be changing repeatedly it ll be almost same or maybe rarely some changes may happen. . So I will be almost working offline with my IndexedDB datas only. . But I cant able to save the SQL datas to my IndexedDB. . Just for now I have inserted some dummy datas which is also hard coded. . I want to automate the process of copying SQL Server datas to my IndexedDB. . Comment : So the data you are saving is in the indexeddb comes directly from the SQL server and users aren t allowed to save their own This will make it a lot easier . I think the best thing to do is expose your data from SQL server as a rest service . Next you will have to insert the data one by one there isn t a batch insert possibility . I would advice to use one transaction for inserting your data . But for awnsering your question do you need a code sample how you can insert the data Comment : For Now I have created a sample HTML file and manually inserted datas of my tables . Everything is working fine but instead of manually inserting the datas I want to make it more easier . Comment : Also I have another problem right now I have created a HTML file it is working fine . But when I try to add it in my .NET project and run it it is thrown me the error saying Microsoft JScript runtime-error : Object doesn t support property or method addEventListener . Am I missing something or do I need to reference something to make it work in my .NET application Comment : On your first comment : I think the best thing to do is expose your data by using a REST service . In the .NET world you have ASP.NET MVC Web API for that . On your second comment . On which object do you get the error The simpelest way of using the indexeddb is by using js promises . This makes the callbacks a bit easier", "Question : 1 . Both indexedDB and local-storage are key-value stores .

They appear to run in the same thread as the async calls were made . How will this not block the UI 3 . indexedDB allows a larger store . Why not increase the size of the HTML5 store 4 . I m scratching my head . What is the point of indexedDB .. . Answer : IndexedDB is not a key-value store in the same way that Local Storage is . Local storage just stores strings so to put an object in local-storage the usual approach is to JSON.stringify https : developer.mozilla.org En Using JSON in Firefox it : .. . .. . This is fine for finding the object with key uniq but the only way to get the properties of myObject back out of local-storage is to JSON.parse the object and examine it : .. . .. . This is fine if you only have one or a few objects in local-storage . But imagine you have a thousand objects all of which have a property b and you want to do something just with those ones where b 2 . With local-storage you ll have to loop through the entire store and check b on each item which is a lot of wasted processing . With IndexedDB you can store stuff other than strings in the value http : www.w3.org TR IndexedDB value-construct : This includes simple types such as DOMString and Date as well as Object and Array instances . Not only that but you can create indexes http : www.w3.org TR IndexedDB index-concept on properties of the objects that you stored in the value . So with IndexedDb you can put those same thousand objects in it but create an index on the b property and use that to just retrieve the objects where b 2 without the overhead of scanning every object in the store . At least that s the idea . The IndexedDB API isn t very intuitive . They appear to run in the same thread as the async calls were made . How will this not block the UI Asynchronous is not the same thing as multi-threaded JavaScript as a rule is not multi-threaded http : stackoverflow.com questions 39879 why-doesnt-javascript-support-multithreading . Any heavy processing you do in JS will block the UI if you want to minimize blocking the UI try Web Workers http : www.whatwg.org specs web-workers current-work . indexedDB allows a larger store . Why not increase the size of the HTML5 store Because without proper indexing it would get increasingly slower the larger it got .

If I just do a simple .. . .. . in an incognito window pointed at my webapp it works fine . If I do the same in the non-incognito window I get the timeout . The important thing is : I get the same timeout problems if I increase the loop size to something big even in a fresh session . So it feels like there s some threshold somewhere that s not quite right . Comment : The Transaction timed out due to inactivity is a Chrome-specific thing that triggers when no activity has been seen from a connnection which usually indicates a hung process .

Answer : There isn t any limit on a single database item s size however there is in some cases a limit on each IndexedDB database s total size .

Long story short the app should be able to run on : .. . .. . One of the major desktop browsers Chrome preferred .. . Safari on iOS .. . Android s native browser based on V8 and WebKit .. . .. . So the question is which technology to choose : IndexedDB or Web SQL Database Regarding Web SQL Database on one hand it is ready to be used in any of the above scenarios . On the other Mozilla has stated Firefox will never implement it and acording to the HTML5 working draft http : www.w3.org TR webdatabase the specification has reached an impasse : .. . .. . This specification has reached an impasse : all interested implementors have used the same SQL backend Sqlite but we need multiple independent implementations to proceed along a standardisation path . Until another implementor is interested in implementing this spec the description of the SQL dialect has been left as simply a reference to Sqlite which isn t acceptable for a standard . Should you be an implementor interested in implementing an independent SQL backend please contact the editor so that he can write a specification for the dialect thus allowing this specification to move forward . IndexedDB is the alternative advocated by Mozilla but it will only come in Firefox 4 . Microsoft is interested and Chrome will support it as well . I know nothing of Apple s plans regarding IndexedDB . I m personally inclined to choose Web SQL Database but just because I m used to SQLite I like the power and expressiveness of SQL and I understand the relational model . IndexedDB for me is an uncertainty . That said I m afraid of betting on the wrong horse . Is it safe to assume support for Web SQL Database will continue to exist even if IndexedDB becomes the standard A note on CouchDB : do you also see it as an alternative .. . Answer : Well as with all things computing the game is abstraction . If you can come up with an adequate layer that works on both a SQL store and a key-value-store then ideally you re isolated from the problem and can support the appropriate implementation on the particular browser . If your data model and access patterns don t fit with the lowest common denominator i.e . a k v store then that pretty much solves your problem right there . If you can use either store then work on a decent access layer and approach the problem from that direction . Mind just because you have a k v store on the back end doesn t mean you have to model your data as only a k v model . Essentially all a DB is on the backend is a k v store . If you don t have an insane amount of data you can do many things . With a large amount of data the hoops you might have to jump through may cost you in performance that you may well not see with a smaller amount of data . All depends . Comment : Great answer i totally agree .", "Question : I ve been playing with IndexedDB in Firefox Ubuntu .. . .. . Is there any way to visualize IndexedDB databases contents Or do I have to do it programmatic-ally .. . Answer : Bleeding edge Chromium builds reportedly allow you to view IndexedDB content in the Resources panel of the Chrome devtools but only I know of one way to view Firefox IndexedDB content non-programmically and that s to load the .sqlite file directly . Firefox s IndexedDB .sqlite files are located at Users USER Library Application Support Firefox Profiles PROFILE indexedDB on OS X and should be C : Users USER AppData Roaming Mozilla Firefox Profiles PROFILE on Windows . I use the excellent and free Firefox tool SQLite Manager https : addons.mozilla.org en-US firefox-addon sqlite-manager which is cross-platform . which looks like this http : i.stack.imgur.com bxrze.png .. . .. . One thing to keep in mind however is that the contents are often stored as binary blobs and are likely not to be human-readable . Keys are stored as text however so they should be able to be read by hand . Update Although local files remain a great way to view IDB databases and stores Chrome does now have great tooling available in the Resources panel . Comment : will take a look at chromium.. .

Thanks for the tip . Yea it shows values as blobs but at least I see all the objectstores keys etc . Comment : Fernando One master trick that we had to develop for IndexedDB is to wait till all transaction ended before starting any schema changes like adding new ObjectStore adding index to the existing store etc . If you like you can check the sources indexedDB.js and taskQueue.js in github.com urbien urbini http : github.com urbien urbini For that we used jquery-indexeddb.js http : nparashuram.com jquery-indexeddb to put IDB requests into taskQueue as promises .

By default in Firefox 4 a site can use up to 50MB of IndexedDB storage . If it tries to use more than 50MB Firefox will ask the user for permission : http : mxr.mozilla.org mozilla-central source modules libpref init all.js 101 .. . .. . In Firefox for mobile-devices Google Android and Nokia Maemo Firefox will ask for permission if a site tries to use more than 5MB : http : mxr.mozilla.org mozilla-central source mobile android app mobile.js 571 .. . .. . .. . .. . .. . If the user grants permission for a site to exceed the 50 MB IndexedDB quota then as far as I know Firefox does not impose any more limits . The only limits on the size of the IndexedDB database will be the user s disk space and operating-system . .. . The localStorage quota is 5000KB and there is no way for a web site to ask the browser for permission to store more than that amount in localStorage . I don t think there s a specific limit for a size of a single item only a global limit but you d need to test that .", "Question : I m building a chrome app which requires a persistent and local database which in this case can be either indexedDB or basic object storage .

If the indexedDB file data persist can i locate and view it 3 . If I can locate but can t view it is it possible to change the location of the indexedDB file 4 . Can I store the indexedDB in a file located on desktop or any other custom location Comment : To that point @Shourya if you are looking to persist the data outside the app you can keep one copy in the app and using an iframe copy it to persist in on a web domain think iFrame or like it using postMessage this way you can move it .

But I can t see why you would want to do that for anyway . Comment : @joseeight i just want to make sure that the indexedDB persist even if I have to reinstall my app or chrome browser Comment : It is unclear to me how the data is stored but the data for indexedDB is stored in C : Users username AppData Local Google Chrome User Data Default IndexedDB on Windows and inside that folder there are folders for each site with indexedDB . I don t think you can configure it to save elsewhere . .. . Answer : If I had these requirements I see a couple of options that you might pursue .. . .. . 1 . Write a simple database backed by the FileSystem API and periodically lock the database and back up that file . This would be pretty cool because I don t know of anyone who has implemented a simple FileSystem API backed database but I could see it being useful for other purposes . 2 . Any edits to the database would be also made to a copy of the database stored on your backup server and I would write functions that could import snapshots from your backup . 3 . Simply write functions to export from your indexedDB to some format into a backup and to import from the backup . All options seem quite time consuming . It would be cool if when you create an indexedDB you could specify an HTML FileSystem API entry file to back it and that way you wouldn t have to do 1 or 2 . I agree that it seems like quite an oversight that an indexedDB is quite difficult to back up . Comment : do you mean to say that i can put indexedDB in a file Comment : No but I am saying that it would be awesome if indexedDB were implemented in this way . However it is not a part of the specification . It would be possible to implement your own database that uses a file for storage .

Does someone read what you unzip into mkfifo file Comment : Yes it will be read after function-call that s why gunzip executed in the background . .. . Answer : The problem is that the kernel will block in the open system call until the fifo is opened for the opposite direction and Tcl creates the redirections in the parent process prior to forking because this allows for much more reliable error-handling in normal circumstances . What you need is to get the O NONBLOCK flag passed into the open syscall but the exec command doesn t give you control over that . So some trickery is required This works by doing the open by hand with the flags we want Tcl maps them in without the O prefix and then passing that descriptor to the subprocess . Note that since this is the write side of the pipe that we re setting up we have to open in WRONLY mode which is sort of what open w would do under the covers minus some flags that don t apply here and plus the NONBLOCK which is the magic we want .

You probably don t want to both read and write to the FIFO in the same process . Some background on how FIFOs are opened : .. . .. . Using open for read-only without specifying O NONBLOCK causes a block until another process opens the FIFO for writing . Similarly an open without specifying O NONBLOCK for write-only blocks until another process opens the FIFO for reading . If you pass O NONBLOCK to open opening for read-only returns immediately but opening for write-only returns an error with an errno of ENXIO unless another process has the FIFO open for reading . Info from Advanced Programming in the UNIX Environment by W . Richard Stevens .", "Question : I have gone through a variaty of different linux named pipe client-server implementations but most of them use the blocking defaults on reads writes . As I am already using poll to check other flags I though it would be a good idea to check for incoming FIFO data via poll as well.. . .. . .. . After all the research I think that opening the pipe in O RDWR mode is the only way to prevent an indefinitely number of EOF events on a pipe when no writer has opened it . This way both ends of the pipe are closed and other clients can open the writable end as well . To respond back I would use separate pipes.. . .. . .. . My problem is that although I have found some examples that use the O RDWR flag the open manpages describe this flag as being unefined when assigned to a FIFO . http : linux.die.net man 3 open .. . .. . But how would you use poll on a pipe without O RDWR Do you think O RDWR is a legitimate way to open pipes Comment : Did you read mkfifo 3 and fifo 7 man pages And you won t get an indefinite number of EOF events... . Can t you open it O RDONLY on one side and O WRONLY on the other side and rthen poll appropriately And fifo 7 explicitly says that opening a FIFO for read and write will succeed both in blocking and nonblocking mode Comment : Yeah you are right fifo 7 mentions it to be OK under Linux although it is no standardized POSIX behavior . The thing here is that I cannot open the reading end with O RDONLY only and the writing end with O WRONLY because by default this will block and that is not allowed in my use-case . So while I can theoretically open it with O RDONLY O NONBLOCKING it will not block but since there might be no writer EOF events will be thrown on poll . So I will have to go with O RDWR to avoid blocking behavior on open and to be able to use poll .. . .. . Answer : According to open 2 http : www.kernel.org doc man-pages online pages man2 open.2.html man page you can pass O RDONLY O NONBLOCK or O WRONLY O NONBLOCK to avoid the open syscall to be blocked you ll get errno ENXIO in that case .. . .. .

Comment : thanks but on linux O WRONLY O NONBLOCK will not work I guess.. . The thing is that I cannot block on open AND want to use poll so when I use O RDONLY O NONBLOCK it will not block but poll will fire EOF events all the time.. . So O NONBLOCK and poll is a bad combination . So it seems that I have to go with O RDWR although its no POSIX standard . So is there a way to use poll on non blocking pipes without O RDWR Comment : I never coded that but the man page says that O WRONLY O NONBLOCK should work without blocking . Did you tested it Of course you cannot poll for open since poll requires file descriptors returned by open Comment : Thanks a lot . I will try this for sure later . I am not going to poll on open . I will use POLLIN on reads after I have successfully openend the pipe... .", "Question : Does mkfifo simply not work with Cygwin A simple set of commands such as .. . .. . just causes the terminal to sit forever with the cursor blinking .

I m using babel-watch which uses mkfifo and since it s running inside the docker-container VM mkfifo can t create a file-pipe in that network shared directory . sidenote : babel-watch actually does works on windows outside docker with cygwin which has a mkfifo.exe utility .. . .. . Is there any workaround to this I tried editing babel-watch source https : github.com kmagiera babel-watch blob 22119922c65edc4f6e8cebe16ac382ac4582f191 babel-watch.js L230 to have mkfifo create a file in var app or var instead where it would still be inside the realm of the docker-container and while this way mkfifo actually works the file changes aren t seen by babel-watch . I guess fundamentally the file change info isn t able to propagate pass the network share barrier - var app server the mount point to var app real directory inside docker . .. . Answer : mkfifo requires Linux OSX environment while var app server was mounted from Windows . So it does not works . So you should ADD or COPY instead of mount volume Comment : I should ve mentioned this earlier but on windows I use cygwin which provides mkfifo.exe and so babel-watch actually does work on windows .

And if I look in tmp myfifo I found that permissions prwxr-xr-x but I want prw-rw-rw- . Comment : The segmentation-fault occurs because you don t check if fopen did open the file it s very likely that the permissions are the cause but it s very bad practice not to check for fp NULL . Comment : GDB is your friend A segfault always indicates a programming error . Comment : You are right but this is an example now I ll modify it . The segmentation-fault become also if I check that fp NULL : Comment : now your check is wrong : - it has to be if fp NULL return -1 .. . Answer : Your writer is segfaulting because you are opening it for writing but do not have permissions to write to it . Hence fp will be NULL and your fprintf fails . The reason for your FIFO having incorrect permissions is probably because your umask is 022 which means those bits are being cleared from the mask you send to mkfifo . This will result in the permissions you see . To fix this either change your umask using the umask call or explicitly set permissions with chmod .

The node code is just an enhanced version of brianc s basic client pooling example https : github.com brianc node-postgres roughly like.. . So Postgres is getting : .. . .. . .. . repeated every 55ms . get jobs is written with temp-tables something like this .. . .. . I ve used the temp table pattern http : stackoverflow.com a 27084540 2036135 because I know that jobs will always be a small extract of rows from really big table 1 in hopes that this will scale better than a single query with multiple joins and multiple where conditions . I used this to great effect with SQL Server and I don t trust any query optimiser now but please tell me if this is the wrong approach for Postgres The query runs in 8ms on small tables as measured from node ample time to complete one job poll before the next one starts . Problem : After about 3 hours of polling at this rate the Postgres server runs out-of-memory and crashes . What I tried already.. . .. . .. . If I re-write the function without temp-tables Postgres doesn t run out-of-memory but I use the temp table pattern a lot so this isn t a solution . If I stop the node program which kills the 10 connections it uses to run the queries the memory frees up . Merely making node wait a minute between polling sessions doesn t have the same effect so there are obviously resources that the Postgres backend associated with the pooled connection is keeping . If I run a VACUUM while polling is going on it has no effect on memory consumption and the server continues on its way to death . Reducing the polling frequency only changes the amount of time before the server dies . Adding DISCARD ALL after each COMMIT has no effect . Explicitly calling DROP TABLE jobs DROP TABLE jobs extra after RETURN query instead of ON COMMIT DROP s on the CREATE TABLE s . Server still crashes . Per CFrei s suggestion added pg.defaults.poolSize 0 to the node code in an attempt to disable pooling . The server still crashed but took much longer and swap went much higher second spike than all the previous tests which looked like the first spike below . I found out later that pg.defaults.poolSize 0 may not disable pooling as expected https : github.com brianc node-postgres issues 319 .

On the basis of this http : www.postgresql.org docs 9.2 static routine-vacuuming.html : Temporary tables cannot be accessed by autovacuum . Therefore appropriate vacuum and analyze operations should be performed via session SQL commands . I tried to run a VACUUM from the node server as some attempt to make VACUUM an in session command . I couldn t actually get this test working . I have many objects in my database and VACUUM operating on all objects was taking too long to execute each job iteration . Restricting VACUUM just to the temp-tables was impossible - a you can t run VACUUM in a transaction and b outside the transaction the temp-tables don t exist . : P EDIT : Later on the Postgres IRC forum a helpful chap explained that VACUUM isn t relevant for temp-tables themselves but can be useful to clean up the rows created and deleted from pg attributes that TEMP TABLES cause . In any case VACUUMing in session wasn t the answer . DROP TABLE .. . IF EXISTS before the CREATE TABLE instead of ON COMMIT DROP . Server still dies . CREATE TEMP TABLE .. . and insert into .. . select.. . instead of CREATE TEMP TABLE .. . AS instead of ON COMMIT DROP . Server dies .

Is there some way of having node-postgres accept the question marks instead or an utility that can convert to postgres style params Note that some sort of Regex-based hack is not acceptable because question marks can be inside quotes or backslash escaped to any depth . Comment : Using a in a query is not MySQL but rather the app layer e.g . Java . This should not need to be changed most likely . Can you show us this query in the context of the code Comment : What version of Postgres are you using Because the documentation mentions using postgresql.org docs 9.1 static ecpg-commands.html https : www.postgresql.org docs 9.1 static ecpg-commands.html as well as this random SO question stackoverflow.com questions 10659737 http : stackoverflow.com questions 10659737 how-can-i-use-a-query-with-placeholder-inside-quotes-perl-postgresql Comment : What is node-postgres and why is it not in the tags as it appears to be the core of your question Comment : @joop It looks like this is a node.js interface to postgres . Which makes my comment irrelevant . .. . Answer : Is there some way of having node-postgres accept the question marks instead NO . And there is no direct correspondence between and 1 syntax because the latter implies parameter re-use while doesn t allow it . For example using implies that you have 3 formatting parameters while 1 2 2 implies that you have two formatting parameters . or an utility that can convert to postgres style params Not likely since there is no direct correspondence the conversion is possible only one-way which would make such an utility fairly useless . You can replace everything yourself with a single regular expression replacing each with + index + 1 . I don t want to convert all my existing SQL from to postgres-style operators like 1 . You don t really have much choice in this . It has to be done . Besides 1 is way more flexible than due to parameter re-use plus optional extensions . For example pg-promise https : github.com vitaly-t pg-promise extends them very nicely with various formatting modifiers that are needed frequently : : json : csv etc.. . .. . .. . Note that some sort of Regex-based hack is not acceptable because question marks can be inside quotes or backslash escaped to any depth . You will likely spend less time converting your SQL by hand than the time to write an utility for the one-way proper conversion .", "Question : Using Node.js and the node-postgres module https : github.com brianc node-postgres to communicate with a database I m attempting to write a function that accepts an array of queries and callbacks and executes them all asynchronously using the same database-connection . The function accepts a two-dimensional array and calling it looks like this : .. . .. . And the function iterates over the array creating a query for each sub-array like so : .. . .. . When I ran the above code I expected to see output like this : .. . .. . However the output bizarrely appears like so : .. . .. . Not only is the second function getting called for both requests it also seems as though the drain code is getting called before the client s queue of queries is finished running...yet the second query still runs perfectly fine even though the client.end code ostensibly killed the client once the event is called . I ve been tearing my hair out about this for hours . I tried hardcoding in my sample array thus removing the for-loop and my code worked as expected which leads me to believe that there is some problem with my loop that I m not seeing . Any ideas on why this might be happening would be greatly appreciated . .. . Answer : The simplest way to properly capture the value of the q variable in a closure in modern JavaScript is to use forEach : .. . .. . If you don t capture the value your code reflects the last value that q had as the callback function executed later in the context of the containing function . forEach by using a callback function isolates and captures the value of q so it can be properly evaluated by the inner callback . Comment : Ahh thank you so much this worked perfectly . I m still getting the issue with drained not appearing in the expected place but obviously that is more an issue with the node-postgres library than with the looping syntax .", "Question : I m fairly new to pg and trying to figure out what the best approach is to loading a set of posts and their associated comments together . For example : I m trying to fetch a 10 posts and comments associated with all those posts like facebooks wall where you see a feed of posts and comments loaded on the same page . My Schema looks something like this : .. . .. . I tried to load both posts and comments on the same postgres function doing the follow : .. . .. . unfortunately it duplicated the posts N times where comment exists where N is the number of comments a post has . However the first solution is that I can always filter it out in Node after fetching the data .. . .. . Also when I try to use group-by posts.id to make it easier to traverse in node I get the following error : .. . .. . The second thing I can try is to send an array of post ids I want to load and have pg function load and send them back but I can t quite the query right : .. . .. . to call it : .. . .. . However even when trying to get value from one index I get the following error : .. . .. . Finally the last solution is to simple make N seperate calls of postgres where N is the number of posts with comments so if I have 5 posts with comments I make 5 calls to postgres with post id and select from Comments table . I m really not sure what to do here any help would be appreciated . Thanks Comment : The first solution is the simplest and fastest . The other will need two queries and two trips to the server . About duplicated posts that is the way it is with relational databases and it is a problem better dealt with in the presentation layer . Comment : are you using only the sql Comment : im using postgres with node Comment : @ClodoaldoNeto is there anyway to use group-by without having that aggregate error show up Comment : Would you like to have an array of records for each post .. .

One of the things I tried to do is to write a short js to populate my database using a file with about 200 000 entries . I noticed that after sometime less than 10 seconds I start to get Error : Connection terminated . I am not sure whether this is problem with how I use node-postgres or if it s because I was spamming postgres . Anyway here is a simple code that shows this behaviour : .. . .. . It fails after about 18 000-20 000 queries . Is this the wrong way to use client.query I tried changing the default client number but it didn t seem to help . client.connect doesn t seem to help either but that was because I had too many clients so I definitely think client pooling is the way to go . Thanks for any help .. . Answer : I m guessing that you are reaching max-pool-size . Since client.query is asynchronous prolly all the available connections are used before they are returned . Default Pool size is 10 . Check here : https : github.com brianc node-postgres blob master lib defaults.js L27 .. . .. . You can increase default pool size by setting pg.defaults.poolSize : .. . .. . .. . .. . Update : Execute another query after freeing a connection . The basic idea is since you are enqueuing a large number of queries with relatively small connection pool size you are reaching max-pool-size . Here we make new query only after an existing connection is freed . Comment : Thanks . I did change it to 25 but it didn t help my original code . Haven t tried it with this one though . I referred to it as default client number .. . oops .. . or was that something else Comment : @DanielSutantyo : how are changing default client number Comment : So I tried both pg.defaults.poolsize 25 maybe even more and pg.defaults.poolIdleTimeout 60000 The first one definitely increase the number of entries I could put in but not by much . Comment : @DanielSutantyo : can you try something like I mentioned in the updated answer The basic idea is to make another query only after freeing a used connection . Comment : Thanks . I am a bit swamped with things until start of next week but I will give it a go ASAP . Anyway nice to learn about queue and release . I also tried an implementation with npm-async library but got the same problem ." ] }

CTE is an Eclipse plugin that ships with ClearCase . In ClearCase version 7.x CCRC only supports web views . Web views are copy based views that communicate with the ClearCase server via http . They perform well in WAN environments . In version 8.0 the ClearTeam Explorer formerly CCRC adds support for Dynamic views . In 8.0 the ClearTeam Explorer supports both Web and Dynamic views .

This is not a true decentralized model since it is does not allow for parallel concurrent evolutions : The branches are mastered in one VOB or another you can only check-in to the master VOB for the branches mastered there though you have readonly access to any branch at any replica . linear version storage : each file and directory has a linear history there is no direct relationship between them like the DAG VCS Directed Acyclic Graph http : en.wikipedia.org wiki Directed acyclic graph where the history of a file is linked to the one of a directory linked to a commit . That means .. . .. . when you compare two commits you have to compare the list of all files and directories to find the delta since commits are not atomic across files or directories meaning there is no single name for all the changes to all the files that make up a logical delta . That also means a merge http : publib.boulder.ibm.com infocenter cchelp v7r0m0 index.jsp topic com.ibm.rational.clearcase.hlp.doc cc main about merge base cc.htm must find a common base contributor http : publib.boulder.ibm.com infocenter cchelp v7r0m0 index.jsp topic com.ibm.rational.clearcase.hlp.doc cc main about merge base cc.htm not always the same as a common ancestor through history exploration see next point . Git is at the opposite end of that spectrum being both decentralized and DAG-oriented : .. . .. . if a node of its graph has the same id as a node of a different commit it does not have to explore further : all the sub-graphs are guaranteed to be identical .. . the merge of two branches is actually the merge of the content of two nodes in a DAG : recursive and very quick for finding a common ancestor .. . .. . alt text http : publib.boulder.ibm.com infocenter cchelp v7r0m0 topic com.ibm.rational.clearcase.hlp.doc cc main images merg base contrib.gif .. . .. . 3-way merging : to merge two versions ClearCase must find a common based contributor in their linear history which can be fairly long for complex version tree http : groups.google.com group comp.software.config-mgmt browse thread thread aaed6a7dfb14ba0e branch sub-branch sub-sub branch .. . and the basic ClearCase merge http : www.tips5.com how-merge-works-in-clearcase command merges a file or directory but it is not recursive . It only affects a singe file or a single directory without its files ct findmerge is recursive .. . .. . file-centric as opposed to the other recent VCS more repository centric : that means the commit is file by file not set of modified files : the transaction is at the file level . A commit of several files is not atomic . Almost every other modern tool is repository centric with an atomic commit transaction but first-generation systems like RCS SCCS CVS and most other older systems do not have that feature . id-managed : each file and directory has a unique id meaning they can be renamed at will : their history will not change since the id remains for the element . Plus a directory will detect in its history any addition suppression of file . When a file is removed rmname it does not know it : only the directory is notified and creates a new version in its history with a list of sub-elements not including the file removed . Create two files with the same size and content they will get the same id in Git -- a SHA1 key -- and will be stored only once in the Git repo Not so in ClearCase . Plus If two files with the same path and name are created in two different branches their id being different means those two files will never be merged : they are called evil twins .. . .. . branches are first-class citizens : most VCS consider a branch and a tag as the same : a single point in the history from which a new linear history can grow branch or from where a description is attached tag . Not so for ClearCase where a branch is a way to reference a version number . Any version number starts at 0 just referenced in ClearCase to 1 2 3 and so on . Each branch can contain a new list of version numbers 0 1 2 3 again . This is different from other systems where the version number is unique and always growing like the revisions in SVN or is just unique like the SHA1 keys in Git . path-accessed : to access a certain version of a file directory you need to know its extended path composed of branches and versions . It is called an extended path name : myFile@@ main subBranch Version . Git does refer to everything through id -- SHA1-based -- : version or commit tree or version of a directory and blob or version of a file or rather of a content of a file . So it is id-accessed or id-referenced . For ClearCase an id refers to an element : a directory or a file whatever its version is . both pessimistic lock and optimistic lock : reserved or unreserved checkouts in ClearCase : even a pessimistic lock reserved checkout is not a true pessimistic one since other users can still checkout that file albeit in unreserved mode : they can change it but will have to wait for the first user to commit his file checkin or cancel the request . Then they will merge their checkout version of that same file . Note : a reserved checkout can release its lock and be made unreserved either by the owner or the administrator .. . .. . cheap branching : a branch does not trigger a copy of all files . It actually triggers nothing : any file not checkout will stay in its original branch . Only modified files will have their new versions stored in the declared branch . flat-file storage : the VOBs are stored in a proprietary format with simple files . This is not a database with an easy query language . local or network workspace access : .. . .. . local workspace is through checkout to the hard-drive update of a snapshot-view . network workspace is through dynamic view combining versioned files and directories access through network no local copy instant access and local files the ones which are checked out or the private files . The combination of distant versioned and local private files allows a dynamic view to appears like a classic hard drive whereas actually any file written is stored in the associated view storage . centralized deported storage : view storage is there to keep some data and avoid some or any communication with the central referential . a workspace can have : .. . .. . a scattered storage : like the .svn subdirectories all over the place .. . a centralized storage : like the view storage in ClearCase they contain information about the files displayed by the view and that storage is unique for a view . a deported storage : the storage is not part of the view workspace itself but can be located elsewhere on the computer or even outside on the LAN WAN .. . .. . Git has no storage per se . Its .git is actually all the repository meta-data oriented : any key-value can be attached to a file or a directory but that couple of data is not historized itself : if the value changes it overrides the old value . meaning the mechanism is actually weaker than the properties system of SVN where properties can have an history .. . Git on the other end is not too keen on meta-data .. . .. . system-based protection : the owner and the rights associated with a file directory or repositories are based on the rights-management of the underlying system . There is no applicative account in ClearCase and the group of users are directly based on the Windows or Unix existing group which is quite challenging in an heterogeneous environment with Windows clients and a Unix VOB server SVN is more like server-based protection where the Apache server can get a first level of protection but must be completed with hooks to have a finer grain of rights . Git has no direct rights management and must be controlled by hooks during push or pull between repositories .. . .. . hooks available : any ClearCase action can be the target of a hook called trigger . It can be a pre or post operation . CLI managed : cleartool is the Command Line Interface from which all actions can be made .

What are the basic ClearCase concepts every developer should know http : stackoverflow.com questions 645008 what-are-the-basic-clearcase-concepts-every-developer-should-know illustrating some major differences and some shortcomings of ClearCase .. . .. . .. . .. . File-centric operations .. . .. . The most single important shortcoming of ClearCase is its old file-centric approach as opposed to repository -centric like in SVN or Git or Perforce.. . .. . That means each checkout or check-in is done file per file . The atomicity of operation is at file levels . Combine that with a very verbose protocol and a network with potentially several nodes between the developer workstation and the VOB server and you can end up with a fairly slow and inefficient file server which ClearCase is at its core . File-per-file operations means : slow recursive operations like recursive checkout http : stackoverflow.com questions 33577 how-do-i-perform-a-recursive-checkout-using-clearcase or recursive add to source control http : stackoverflow.com questions 138321 how-can-i-use-clearcase-to-add-to-source-control-recursively even by clearfsimport . A fast LAN is mandatory to mitigate the side-effects of that chatty protocol . Centralized VCS .. . .. . The other aspect to take into account is its centralized aspect even though it can be distributed with its multi-site replicated VOB feature .. . If the network does not allow access to the VOBs the developers can : .. . .. . still work within snapshot views but with hijacked files only .. . wait for the restoration of the network if they are using dynamic views .. . .. . Expensive Distributed VCS option .. . .. . You can have some distributed VCS feature by replicating a Vob . But : .. . .. . you need a special kind of license to access it . that license is expensive and add to the cost of the regular license .. . any vob that uses the replicated vob admin vob admin pvob .. . must be replicated as well meaning some projects not directly concerned with a distributed development will still have to pay multi-site license.. . .. . .. . Old and not user-friendly GUI .. . .. . the GUI is very old school and impractical mid-90 s MFC look completely synchronous GUI meaning you have to wait for a refresh before clicking elsewhere : when browsing baselines you cannot quickly look for one in particular . the GUI on Unix is not exactly the same than on Windows the latest 7.1 version is better but not there yet .. . the installation process is quite complicated although the latest Installer Manager introduced by CC7.1 is now a coherent GUI on Windows or Unix and does simplify the procedure .. . the only real rich application has only been developed for CCRC the Remote Client .. . .. . UCM inconsistencies and in coherencies .. . .. . As mentioned in How to Leverage ClearCase s features http : stackoverflow.com questions 449549 how-to-leverage-clearcases-features dynamic views are great a way to see data through the network without having to copy them to the disk but the main feature remain UCM : it can be a real asset if you have big project with complex workflow . Some shortcomings on that front : .. . .. . the dependencies between components is not well managed for a depth superior to one because of the bug of parasite baseline http : www.ibm.com developerworks forums thread.jspa threadID 74125 .. . UCM still has some in coherencies and inconsistencies as documented in CM Crossroads http : www.cmcrossroads.com component option com 5Ffireboard func view id 58775 catid 31 Itemid 593 .. . .. . Limited policies with Base ClearCase .. . .. . Using ClearCase without using UCM means having to define a policy to : .. . .. . create branch otherwise anyone can create any branch and you end up with a gazillon of them with merge workflow nightmare .. . put labels otherwise you forget to label some files or you put a label where you were not supposed to or you move gasp a label from one version to another : at least UCM baselines cannot be moved .. . define changeset . ChangeSets only exist with UCM activities . With Base ClearCase you are reduced to clever cleartool find requests.. . .. . .. . No application rights .. . .. . ClearCase right management is entirely built on system rights . That means you need to register your user to the correct system group which is not always easy to do when you have to enter a ticket to your IT service in order for them to make the proper registration . Add to that an heterogeneous environment users on Windows and server on Unix and you need to register your user on Unix as well as Windows with the same login group name . Unless you put some sort of LDAP correspondence between the two world like Centrify http : www.centrify.com products overview.asp .. . .. . No advanced API .. . .. . only CLI is complete cleartool is the ClearCase Command Line Interface meaning that any script in Perl or other language consists in parsing the output of those cleartool commands .. . ClearCase Automation Library CAL http : stackoverflow.com questions 268595 how-do-i-get-latest-clearcase-label-programmatically-from-c 269624 269624 exists but is quite limited .. . Java API exists but only for web views for the CCRC client . View Storages not easily centralized backed up .. . .. . The View storages are the equivalent of the .svn of SubVersion exept there is only one view storage per view instead of many .svn in all the directories of a SubVersion workspace . That is good . What is bad is that each operations within a view a simple ls checkout checking .. . will trigger a network request to the view server process that manages your view server . 2 options : .. . .. . declare your view storage on your workstation : great for scalability you can have as many view as you want without taxing the LAN : all communications are directly done on your workstation . BUT if that machine dies on you you loose your views . declare your view storage on a centralized server : that means all view server process will be created there and that all operations on a view by any user will have to communicate with that server . It can be done if the infrastructure is right special high-speed LAN dedicated-server constant monitoring but in practice your LAN will not support this mode . The first mode means : you have to backup yourself your work in progress private files or checked-out files .. . The second mode means : your workstation can be unavailable you can just log on another a get back your views execpt for the private files of a snapshot-view .. . .. . .. . .. . Side discussion about dynamic views : .. . .. . To add to the dynamic view aspect it has one advantage it s dynamic and one shortcoming it s dynamic . Dynamic views are great for setting a simple environment to quickly share a small development between a small team : for a small development effort a dynamic view can help 2 or 3 developers to constantly stay in touch one with another seeing instantly when one s commit breaks something in the other views . For more complex development effort the artificial isolation provided by snapshot-view is preferable you see changes only when you refresh - or update - your snapshot-view .. . For real divergent development effort or course a branch is still required to achieve true code isolation merges will be required at some point which ClearCase handles very well albeit slowly file-by-file .. . .. . The point is you can use both for the right reasons . Note : by small team I do not mean small project . ClearCase is best used for large project but if you want to use dynamic views you need to setup up task branches in order to isolate a small development effort per branch : that way a small team a subset of your large team can work efficiently sharing quickly its work between its members . If you use dynamic views on a main branch where everyone is doing anything then any check-in would kill you as it could introduced some build breaks unrelated with your current development effort . That would then be a poor usage of dynamic views and that would forget its other usages : .. . .. . additional way of accessing data in addition of snapshot views meaning it is a great tool to just see the files you can for example use a dynamic view to tweak its config spec until you see what you want and then copy those select rules into your usual snapshot-view .. . a side view to make merges : you work with your snapshot-view but for merges you can use your dynamic sister-view sister as in same config spec in order to avoid having a failed merge because of checked-out files on which you would be currently working on your snapshot-view or because of a snapshot-view not completely up-to-date . Once the merge is complete you update your regular snapshot-view and resume your work . Developing directly in a dynamic view is not always the best option since all non-checked-out files are read over the network . That means the dll or jar or exe needed by your IDE would be accessed over the network which can slow down considerably the compilation process . Possible solutions : .. . .. . one snapshot-view with all in it .. . a snapshot-view with dll or jar or exe in it files which do not changes every five minutes : one update per day and dynamic view with only the sources visible . Comment : I still don t get what s so great about dynamic views . I admit I don t have to do updates anymore but if someone breaks the build I immediately have to work with that broken build and cannot just not update till it s fixed again . Comment : @VonC s point was that it works in a small team . Small teams by nature check in early and often with small changes in each commit . Therefore it should not be difficult to figure out who broke it and what they did . However why would small teams buy ClearCase The cost and workflows of other options are better suited than the dated ClearCase . Comment : I m on a small team . We use Clearcase because its a company standard . Dynamic views basically waste a day for me each and every time someone else commits . Comment : Also if you are EVER having developers make commits directly to a main branch then no VCS will help the fact that you don t have a development-process that makes any sense . Comment : Hi .

Once I have manually unmounted all of the irrelevant VOBs from the corresponding dynamic views but after a restart of my PC all the VOBs are appearing again every where . I don t want to view all the 50 VOBs in each dynamic view . Is there a solution for this issue PS : - I am not a clearcase admin expert . Please suggest . .. . Answer : Firstly you can cleartool umount https : publib.boulder.ibm.com infocenter cchelp v7r0m0 topic com.ibm.rational.clearcase.cc ref.doc topics ct mount.htm all vobs with .. . .. . Secondly you can mount them without making them persistent : .. . .. . Through the GUI they are generally mounted as persistent like if you did : .. . .. . That means they are recorded in the Windows registry in oprder to be mounted again automatically at the next Windows session . If you mount them through a script without the -persistent option you won t have that problem . Finally know that if one of your dynamic view need a vob then you need to mount it obviously . But that same vob will then be visible on all your dynamic views it will be mounted at least even if no version in it is selected by the other views config spec . To resolve that you can add-in another dynamic view which shouldn t see a particual vob : .. . .. . you can use and not in a config spec even in Windows .. . .. . That will make that vob invisible for that dynamic view while still being mounted and available for the first dynamic view which needs it . Comment : Thank you VonC . When i right-click on my windows dynamic view i can only see foundation baselines i dont see any place where i can amend the config spec to add element aVob .. . -none . please suggest . Comment : @Subba I am more a command-line of guy than a GUI user But even with the GUI when selecting properties on a dynamic view you can access the Config Spec tab in which you can add any rule you like . Example in command-line of config spec modification : stackoverflow.com a 15656418 6309 http : stackoverflow.com a 15656418 6309 stackoverflow.com a 1346985 6309 http : stackoverflow.com a 1346985 6309 . The last link brings actually more details on how and where put that non-selection rule in your config spec .", "Question : Because I m currently struggling to learn IBM Rational ClearCase I d like to hear your professional opinion .

I would like to add one reason to stay away from CC or any other commercial source control system . Your vital business data is hostage to ClearCase . You can t get it out . Your vital business data is the code its version history and all metadata such as commit comments who checked in and when . All software will have a limited useful life . You should always ask yourself when you introduce a new system that swallows important business data whether it is code bugs customer data or what not : How do I get my data out again If you can t answer that question you should not introduce that system . When we migrated out we lost most of our history and all of our metadata . Essentially we only have history corresponding to released versions but information about what changes were done in response to what customer requests is lost we have that data in the customer support and bug ticket-system so it is not completely lost but the coupling to the source code is gone . This will be somewhere between a nuisance and a problem for us on short to medium term . In a couple of years time it is not important anymore but perhaps for 1-3 years it will matter . There are commercial tools to migrate CC to other SCM but they were not deemed adequate to our needs and I doubt it would have been feasible . The minimal export we did took long enough . The lesson learnt is : Never entrust vital business data to proprietary systems .", "Question : Because I m currently struggling to learn IBM Rational ClearCase I d like to hear your professional opinion .

I m not really here to persuade you that one is better than the other except by way of making a few points : .. . .. . If you re comparing git and ClearCase I respectfully submit that you need to better define your needs - if you are considering ClearCase for a good reason the git probably isn t even in the equation - it s far too new to trust for enterprise-level source control imo . ClearCase introduces a lot of concepts into the version-control space that other systems don t have so it can be pretty daunting and confusing . Especially if the only experience you have is reading the documentation as appears to be the case for a few people here . ClearCase is definitely not well suited to huge code bases supported by developers who are not on a LAN with a VOB server . You can have many replicated multi-site VOB servers to get them close to remote developers but this isn t necessarily practical if those remote sites are just a single developer . Do you want file versioning or repository versioning This is a pretty important question and one that will necessarily filter out an entire set of tools making your job easier . Repository versioning has a lot of advantages and it s not new like some posters claimed - commercial tools like Perforce have been around for more than a dozen years and there may have been tools that did repository versioning even before Perforce but it isn t a panacea . With a sufficiently large installation of any source control system you re going to need help . When considering tools you need to consider how easy it will be to find people to help you either job applicants who have experience or consultants who will be there at a moments notice to address any issues . There s no such thing as a maintenance-free SCM system and assuming you have one will get you into more trouble than picking one that requires too much administration . Don t pay too much attention to people who talk about how bad dynamic views are - bad SCM policies are bad regardless of the tool you re using . Your configuration-management policies and practices have to be separate from your choice of tool - no tool will stop people from smashing all over your codebase if you don t define sensible branching-and-merging policies . If someone suggests that having developers directly commit onto main is ever a sensible idea you might want to walk away from that conversation . ClearCase is a fine tool but it is a complicated tool . There is no getting around this - it does not have an easy install mode . : - From a technical standpoint there s nothing that git or SVN can do that ClearCase cannot although often the terminology is different since Open Source projects tend to just invent new taxonomy where there already existed one but some things are definitely easier harder for a given system depending on their design . ClearCase snapshot views are basically the same thing you would have if you checked out a repository from SVN or CVS - it s a local copy of the source code on your machine with pointers back into the central server for tools to query version history etc . You can work with these views without any network connection to the ClearCase server at all once they have been created and you can recycle them to avoid downloading your entire repository again when you want to move to work on another branch for example . Dynamic Views are basically a ClearCase invention and the standard operating mode for a LAN . They appear the same as checking out an SVN repository but they don t actually copy any files until you make changes . In this way the view is available immediately but it obviously cannot be worked with if the main clearcase server is unavailable and is unpleasant to work with over a high-latency connection . They also have the convenience of being able to be mounted as a network-drive on any machine with access to the server on which they were created so if your windows workstation dies you can just log onto another one mount your view and get back to work since all the files are stored either in the VOB server for files you haven t modified on this branch or the view server for files you have created or modified just in this view . Also and this deserves its own paragraph....clearmerge is nearly worth the price of admission alone . It s hands down the best merge tool that I ve ever used in my life . I firmly believe a lot of bad practice in SCM has developed because of a lack of high-quality merge tools so CVS users never learned to use branches properly and this fear of branching has propagated to the current day for no particularly good reason . Ok all that being said if you re looking for reasons not to use ClearCase they re not hard to find although I think that s the wrong way to go about it . Really you should need to come up with good reasons TO use ClearCase not reasons for NOT using ClearCase . You should come into any SCM situation assuming that ClearCase is too much tool or too complicated a tool for the job and then see if you have some situation that encourages you to use it anyhow . Having IBM or Rational logos is not a good reason. . : - .. . .. . I would not even consider ClearCase unless you could say yes to all the following statements : .. . .. . You do now or will eventually have more than 50 developers working on the same codebase . Most of those developers are centrally located or have high-throughput low-latency connections to a central location . You have a set of SCM policies and can identify how to use ClearCase to enforce those policies really you should consider this for any tool .. . Money really is no object Comment : if your windows workstation dies you can just log onto another one : only if your view storage was not on your workstation and centralized view storage is not always possible due to the additional stress it puts on the network each view operation then involving a network access Comment : OK clearmerge is a good tool I ll grant you that But no way is it worth the price of the entire system - either in dollars or in sanity . Comment : @VonC : on an even halfways well designed LAN dynamic views don t cause significant network traffic say compared to windows boxes smb ing all over the place all the time . In my experience it s more efficient and more convenient than having a CVS or SVN checkout exported to NFS and mounted somewhere else .

What is difference between Eclipse Virgo and Eclipse Gemini I understand what OSGI does in general . .. . Answer : From the Virgo proposal : .. . .. . Gemini .. . .. . Virgo provides a runtime enterprise application model on top of Equinox with integrated application and provisioning support . The Gemini project at Eclipse.org provides implementations of enterprise capabilities that can be exploited by such applications . The Virgo kernel provides just the foundational capabilities and depends solely on the Gemini Blueprint Service project . The Virgo server distribution pre-integrates the Gemini Web Container and Blueprint Service projects .

Is there a way to use OSGi on every Java EE appliction server Comment : Does this answer http : stackoverflow.com questions 12582709 osgi-and-application-servers help you .. . Answer : Currently no . Some application servers such as Virgo Glassfish IBM Websphere etc directly support OSGi deployment but they support it in different ways . Other application servers have no built-in support for OSGi . However even in application servers with no OSGi support it is possible to embed OSGi within a traditional Java EE deployment artifact such as a WAR or EAR file . Some example code for embedding OSGi is shown in a blog post http : njbartlett.name 2011 03 07 embedding-osgi.html I wrote some time ago . Comment : Neil s right in general but if you pick app servers that directly support OSGi deployment you can in principle develop application bundles which will run on Virgo as well as other app servers . You just have to deploy the bundles in app server specific ways . That s a benefit of OSGi being a standard . Comment : Thanks Glyn . I did indeed mean that the deployment aspects differ between these servers but totally agree that the code can be portable .", "Question : Hey .. .

I do not want to use that way for now . I prefer same as class path loading . Please help me how to use in virgo . Thank you regards gopy .. . Answer : Considering that in OSGi each bundle has its own classpath nothing would prevent you from putting your property files in the same bundle or any other type of resource for the matter including even non-OSGi-fied JARs http : wiki.osgi.org wiki Bundle-ClassPath and reading it like you would usually do in a single-classpath environment . Having said that reading your properties through the Compendium Services benefits you with the same modularity benefits that porting your WAR had as the property file s would be considered a separate bundle of artifact type configuration in Eclipse Virgo terms that you can modify in runtime and refresh independently for the changes to take effect according to your design . Comment : Hi Hesham thank you for the reply Yes for bundle i am using compendium services to load properties but i deployed 4 more traditional war files which is using common properties files . before i copied common properties file in tomcat lib folder which is treated as common classpath to all war files . i do not want to put properties file inside each war file .", "Question : I am trying to integrate restlet in an application using Eclipse Virgo as the application server .

Of course I can start the restlet own web server on a separate port than the Eclipse Virgo one but I had no success using its web server . Is it at all possible Update .. . .. . There is also Spring involved into the story so I think this will make things even more interesting . The Spring related configuration is below : .. . .. . I am now getting this exception : .. . Answer : In fact you don t necessary need the extension org.restlet.ext.osgi to make work Restlet within an OSGi container . As a matter of fact with the OSGi edition all Restlet jars contain valid MANIFEST files even before version 2.2 . Virgo supports Web bundles so you can embed a Restlet application in it leveraging the extension org.restlet.ext.servlet . You can have a look at the following link for more details : https : github.com restlet restlet-tutorial blob master modules org.restlet.tutorial.markdown 02 Server Side 04 Server Deployment 02 Servlet Deployment.md . Otherwise I would be interested in having more details about the errors you have when trying to use Restlet in such context . Edited Following the new elements added in the question .. . .. . You should configure the Restlet servlet for Spring . This servlet would replace the one from Spring itself DispatcherServlet . The listener ContextLoaderListener must remain since it s used to manage the Spring application context within the Web bundle . Here is a sample of configuration for this servlet : .. . .. . The servlet will look for a bean named myComponent in your Spring application context . Here is a sample of configuration of Restlet within this application context : .. . .. .

Answer : You should use OSGis ConfigurationAdmin for doing this . You can deploy your properties files into VIRGO HOME pickup and then consume the properties from ConfigurationAdmin Service over the configurations pid . Virgo recognizes your properties files in its pickup folder and automatically exposes them over the ConfigurationAdmin Service . You could also list your properties files in a plan file if you use plans to deploy your bundles as an application .

Answer : Be aware that Virgo Nano doesn t include servlet container such as Tomcat or Jetty so you will need the HttpService to bind your REST services . You can try with OSGI JAX-RS Connector from EclipseSource .

These lines must be feeding into Phalanger to load this extension when compiling I think know . After that everything seems to compile and run fine Thanks Jakub Comment : Right . Just to clarify that .mng file Phalanger is completely in C managed code - still it is needed to support some legacy PHP extensions which are in C language native-code .

This is just an test exercise and I want to actually convert Codeigniter into dll so that I can remove source code from wwwroot inetpub folder and just put compiled dll into the web root folder at the time of publishing . While doing it I get codeigniter default page running on IIS successfully using phalanger . Then I compiled it using phalanger command and put all phalanger dll into the bin as described on their wiki . So now I have compiled dll as well source code into the web root . Which is also working fine . The moment I move source of codeigniter php files including folder system application out of webroot it stops working . As described on phalanger features a compiled dll should work but its not working . Instead everytime we access page it is loading it from the php file . Does any one has any idea how to convert it to dll and host only dll on and not the source code . Or I m missing something here . Any help in this regard is appreciated . .. . Answer : Phalanger actually loads scripts from bin WebPages.dll and additional DLLs specified in configuration . And only if the script is not found in provided DLLs it looks at filesystem . The problem can be caused by the fact it only works within inclusion statements include require include once require-once . File system functions work with filesystem only and it is common practise in PHP to check for various files existence and content . Mostly to check if configuration is present plugins are loaded parse additional comments from script etc . So you can remove all .php files that are in DLL already but you should leave these files which CodeIgniter uses through fs functions . Comment : Okay I got it .

Specify target : exe parameter to build executable file . List any reference to .NET or extension library by adding r : .. . parameter . .. . Answer : Phalanger works as a compiler and runtime for PHP . The easiest way is to install Phalanger Tools for Visual Studio which allows you to create build and debug console-application . Anyway without Visual Studio first you have to compile the code .. . .. . Optionally if you have more files in your project you should list them all and specify the entering script file .. . .. . Which compiles everything .php in current directory and subdirectories and specifies hello.php to be the entering script file . This creates an executable file hello.exe . After you succeed with this basic example you may be interested in using some PHP extensions like GD2 .

Integrating phalanager as a view model looks fairly easy apart from one point . I m not sure how to pass the model to the page script . Any ideas how this might be achieved One idea would be to calling a static .NET method from the php script but it feels a bit hacky . I d like be able to just pass the parameter to the script and have the script be able to pick it up in a variable . .. . Answer : Using .NET on the backend and PHP using Phalanger on the frontend looks like a good scenario . I think that the best option is to implement the model in .NET and use PHP to implement controllers and views either directly or using some PHP framework . Calling a .NET model from PHP compiled using Phalanger is quite easy because the PHP code can access .NET objects . Assuming you have a C DLL containing a namespace DemoDataLayer with the following type : .. . .. . Then you can reference the C library from the Phalanger website using web.config and use PHP extensions provided by Phalanger to use the Data class as-if it was a standard PHP object : .. . .. . To configure the reference you ll need to add the C DLL to the bin directory and include it in classLibrary element . The import namespace syntax used above is a Phalanger-specific language extension for using .NET namespaces that needs to be turned on using PhpClr feature : Comment : Thanks for the answer Tomas but I was hoping to do it the other way round : have the .NET code call the php script and pass it parameter to automatically create a binding like categories to minimize the amount of php .net code that had to be written . Is this possible Comment : @Robert : Yes there is some way to do that too I ll need to check for the details . The question is how do you want to instantiate the PHP code If you re using ASP.NET MVC I assume you d like to have something like return PhpView foo.php in your controller There is no support for this currently but it sounds interesting and it could surely be done Comment : I have my own mvc like framework which has it s own F ish way of invoking views but basically you d do something like return PhpView foo.php to invoke the php view . I ve been looking at it right now and it looks difficult as all the stuff relating to compilation of scripts is marked as internal . Looks like it d need to make a custom build of phalanger and change some visibility settings .", "Question : I have three php classes Im trying to use in my .net application . I used Phalanger to take those three classes and make a .dll file using this command : .. . .. . Which of course outputted Client.dll as well as a Client.pdb files . From there I went to VS2012 and created a new asp.net application and added the Client.dll as a reference . However I do not see the public methods from any of the classes and the object browser window shows : .. . .. . Client Client Base Types Object so that I only have the methods of type Object .. . .. .

Which of course means that it doesnt know what or where ScriptContext . However this tutorial is from 2007 so I dont know if its just to far out of date or where I should get that class from The other tutorial http : www.codeproject.com Articles 17311 Phalanger-PHP-for-NET-Introduction-for-NET-develop 5 1 I found is just as old . It says : .. . .. . If you want to use existing PHP source developed for standard interpreter without modifications you have to use legacy mode but when you want to develop new PHP project you can consider using pure mode .. . .. . But I cannot find the step for legacy mode within the document and would prefer that over trying the pure mode so that I dont have to change edit my existing php code . I did try pure mode however it wouldn t compile phalanger compile with the command above adding the DynamicObject.php class to the command . How can I get to my public methods within the php class .. . Answer : creates DLL in legacy standard mode . This DLL contains weird namespaces needed for compatibility with PHP semantics . these namespaces separate code from different script files . .NET interoperability overview of Phalanger 3.0 http : www.php-compiler.net blog 2012 net-interoperability-overview-of-phalanger-3-0 blog post describes how to use scripts compiled in standard mode . Command line option pure+ tells compiler to create so-called pure mode assembly . In this mode compiler concatenates all the source files and compiles them as one as C does without any weird namespaces . If you specify Export attribute above the PHP class declaration resulting DLL will look as it would be compiled from C code and you will be able to reference it and use its classes normally . Comment : If you have a phalanger project in visual-studio go to properties and change Mode to Pure . Comment : Great link thanks Part of my problem however is that I cannot find the class ScriptContext . The doc mentions that VS express edition isn t support so is that why I do not see that class Comment : PHP.Core.ScriptContext is in PhpNetCore.dll .. . VS Express has no support for 3rd party plugins - this means you cannot install Phalanger Tools plugin that utilize Phalanger PHP projects and editor features but it won t affect C editor experience Comment : Thank you I didnt realize that I had to browse to it at the C : Program Files Phalanger 3.0 Bin folder for that . Comment : If you get a chance please check out my followup question about the fact that phalanger isnt seeing my php classes stackoverflow.com questions 12901567 http : stackoverflow.com questions 12901567 phalanger-cant-find-my-php-classes", "Question : Zend framework is just a collection of PHP classes .

Answer : Phalanger is a complete PHP compiler+runtime and in the result it should compile and run any PHP script including Zend Framework . However it is still in development - since Phalanger is complete opensource reimplementation of PHP to .NET there are differences or it is just a bug . I suggest to report the misbehaviour at http : phalanger.codeplex.com workitem list basic ideally with small test case that points out the difference between PHP and Phalanger .", "Question : I need to embed some resource in a pure compiled dll written in php using phalanger . These are txt files tha I set in visual-studio as Embedded Resource . My problem is that I cannot use the Assembly class to get the resource using GetManifestResourceStream . I tried code like this : use System Reflection Assembly .. . .. . My question is : how do I get access to embedded resources in phalanger Many thanks .. . Answer : This question is old but the part of the Phalanger code Php.Core.Emit.AddResourceFile method responsible for this hasn t changed since this was asked . I faced the same problem and solved it in almost non-hacky way . You have to provide alternative name res : path to filename alternative-name for this to work though . Straightforward GetManifestResourceStream as suggested by Jakub does not work because Phalanger does not use System.Reflection.Emit.ModuleBuilder.DefineManifestResource like I think it should when supplied with unrecognized file-format . It uses ModuleBuilder.DefineResource which returns ResourceWriter instead that only really suited for .resources files . And this is what dictates the requirement to use ResourceReader when you need to read your resource . Note : This answer applies to Phalanger master branch at the time of writing https : github.com DEVSENSE Phalanger tree e13ea87f1a635c577a409d48276f31b097a670a6 and prior versions since circa 2011 .

An example of something that causes issues is : .. . .. . the compiler complains that : .. . .. . Does anyone have any ideas who is using the latest version of Phalanger .. . Answer : List is PHP keyword and it is not valid PHP identifier . However Phalanger has additional configuration option which allows to use such keywords in identifiers . Add following into your .config file : phpNet compiler set name LanguageFeatures add value CSharpTypeNames .. . .. . This allows compiler to treat disallowed PHP keywords as identifier . Comment : Works perfectly thank you Is the a location on your wiki where all of this is listed", "Question : I want to compile a PHP application where I ve used css files and javascript code . I ve choosed to work with Phalanger but I can t find any tutorial that mention how to compile such aplication . So is it possible or Phalanger just compile php files .. . Answer : Phalanger is server-side compiler of php code and js is client-side script . This means Phalanger does not handle js either in php files or in standalone js files . Js code in php files is simply outputted to the response as it would using regular php . You can consider using additional tools for optimizing and minimizing js files .", "Question : Is it possible do code-coverage for manual-testing on a .NET server which has phalanger for compiling php code .. .

The package doesn t target any framework . .. . .. . Its a phpproj PHP project created from VS.php extension how can i use nuget with phpproj type project . .. . Answer : VS.php is only PHP extension nothing to do with Phalanger . Phalanger comes with Phalanger Tools for Visual Studio https : visualstudiogallery.msdn.microsoft.com 419916fb-ec89-4f18-ba97-75cf66037797 . It cannot co-exist with VS.php since both provide PHP Editor functionality . Then if you create new Phalanger Web Project it should allow you such features as NuGet . Comment : I am using Phalanger as PHP compiler . I am not using PHP tools because Vs.PHP and PHP tools conflicts as they both target the same configuration setting . My question is about adding nuget to phpproj of Vs.PHP the Phalanger is mentioned to complete info about my environment i m not saying this is due to Phalanger because I m aware its a compiler and its role will come at the time of compile . The issues seems to be with Visual Studio and Vs.PHP integration . Comment : VS.Php integration uses deprecated format of phpproj files not msbuild and does not support such features . You may contact jcx soft . to implement such features . Phalanger Tools and PHP Tools are built on top of MSBuild and supports this extensibility naturally .", "Question : How to use a php-extension like mcrypt My first thought was to find mcrypt.php and simply include it context.Include mcrypt.php false but of course that doesn t exist since it is written in C . .. . I was reading over Writing compiled PHP extensions in PHP http : www.php-compiler.net blog 2012 php-extension-in-php post from the blog but that seems to be about creating your own extension for use in .net . But maybe Im wrong considering this statement : Implement Phalanger extension in PHP langage . When you take your PHP library and compile it using Phalanger the result is DLL working as any other extension But even still phpc phalanger php compiler is not going to compile c code as far as I know though I haven t tried . these are the calls my php class is trying to make : mcrypt module open mcrypt enc get key size mcrypt enc get block size Comment : .NET has its own set of crypto libraries .

Plus learning about this phalanger stuff is fun . in the end if it cant be done thats what i will have to do .. . Answer : It s not that complicated install and use MCrypt . For nix users PHP.net provides a source of information in this page http : br2.php.net manual en mcrypt.installation.php . But for Windows there is not too much information . However it s easy too . You just have copy the file libmcrypt.dll from a PHP Binary save it in ext directory and enable it : .. . .. . Note : In WINDOWS environment PHP EXtensions are usually anemd as php so you have to rename the DLL or the PHP.INI line above . After that restart Apache . But before you do this check your phpinfo first because some packages and or distributions comes with a pre-compiled static MCrypt . Run it and check for with-mcrypt static and or MCrypt group with mcrypt support enabled Comment : sorry but this is not what im trying to do . Im using phalanger to compile php scripts at runtime in the .net environment . Quite different then using php on a server like Apache or even IIS Comment : It s not what you said in the first topic .

Comment : @JakubM ek I tried with 3.0 AND 4.0 and the error persists . .. . Answer : The error is telling you that the class JLogEntry hasn t been defined yet it has been referenced by something the expects it to be defined . This means a dependency wasn t satisfied . Your log.php is dependant on a file that defines the JLogEntry class . The JLogEntry class is defined in entry.php according to this : .. . .. . http : www.reference.joomlademo.de nav.html classes index.html .. . .. . and this : .. . .. . http : www.reference.joomlademo.de nav.html classes index.html .. . .. . So for whatever reason you re not satisfying that dependency . If I was on your system I d poke around for that file check if it exists is corrupt correctly versioned or otherwise prevented from being executed . If you still suspect something is hinky with your Phalanger compiler then test it . Write a simple hello world http : stackoverflow.com questions 18849763 hello-world-in-phalanger-php-compiler and prove whether it works or not . Infact do it in the same file after backing up the file to prove whether it s executing . The compiler is working at some level or else it wouldn t be showing you error messages . Edit : .. . .. . According to @highcore the Phalanger 3.0 compiler fails to implement regular expressions in the way Joomla expects . Joomla relies on this to resolve the filenames it will include . Thus entry.php is never included leaving JLogEntry undefined . The suggested work around is to avoid reg ex and split the file names .

I only get an additional separate Stacks graph . It s ok but not where I d expect it i.e . in the Generic Events window . My question was related to Generic Events in general not only to user mode providers . Maybe other kernel flags do not have corresponding user mode provider do they so it s not clear for me yet.In addition if I do it this way symbols are missing again . Do we have to add a minimum set of providers to get symbol support Comment : generic events user mode events . Click on Open View Editor and activate he stack column here . symbols are missing because NETWORKTRACE is not enough . Use NETWORK which captures PROC THREAD+LOADER both MUST be used all the time Comment : Sorry but this is not right because networktrace is a kernel flag and the events are shown in the generic events graph . Anyway I ll just have to accept but not understand that there s no Stack column in that graph . Regarding symbols I found out meanwhile too thanks . Comment : there are stacks if you activate them . I use this often . But for network there is no stack option . Here you have to activate the usermode providers that I told you .

Inside of repo are trunk and branches directories . Within branches there are several dozen release branches e.g . 1.0 1.1 . These branches directories contain a relatively large application . I want to add an external at the root of repo called myExternal . When I define the external the only way to get SVN to create the myExternal directory is to run svn up from the root of repo . However this will also cause the entire contents of branches to be checked out which is unacceptable we have many developers that need to get myExternal added to their copy of repo and can t have all of them checking out gigabytes of unneeded branches .

Answer : Yes that is the known issue of subversion externals are not created unless depth infinity http : subversion.tigris.org issues show bug.cgi id 3311 . I think there is no way as to redesign your directory structure so that myExternal is attached not to the repo but to its subfolders e.g . set on trunk and every folder in branches .

I want to move away from externals sub-repos anyway so I thought I could flatten them out as part of a svnsync .

Comment : Does it work properly if you put the command option before the file path arguments i.e . svn cp --ignore-externals A B .. . Answer : You are misunderstanding what --ignore-externals is for on the copy subcommand . This flag only affects working-copy operations . When you copy one working-copy path to another it prevents svn from processing all the svn : externals properties on copied items to check out their targets . It does not prevent svn from copying the properties themselves those get copied along with the folders they have been set on . Removing those properties would be a change to the copied objects and svn does not change objects while it copies them .

Answer : I forgot to add comments and stuff to this question . I read some in depth stuff on the svn : externals documentation and found that it must create a sub-folder . That s ridiculous limitation to have IMO but it is what it is . I ended up putting the external on the top-level folder in this case . It hasn t broken anything to my knowledge but I also haven t worked on that particular project in a while now . The other devs haven t complained . Also I m leaving this question unanswered because there is no solution to the problem yet . Comment : That s outdated information then . You can do externals file-by-file using file externals . Directory externals must create a subdirectory because a directory external basically creates a brand new independent working copy . This is also similar to how Subrepositories work in systems like Mercurial and Git . Comment : I didn t want to specify each file separately .

However these applications share the same database abstraction-layer and several of the same common components . We d like to share the common bits between the apps somehow . The current idea we have looks like .. . .. . Now we d like the itg-app repository to have an externals reference to the itg-common repository . The problem is we want e.g . itg-app trunk common to be linked to itg-common trunk itg-app branches foo common to be linked to itg-common branches foo etc . That is the general pattern is itg-app BRANCH common - itg-common BRANCH . Now in principle we could create these externals but problems arise whenever we would try to merge . E.g . merging from trunk to branches production would overwrite the svn : externals property to make branches production common to point to itg-common trunk . Does this make sense If it does is there some way around this problem If it does not why not and what should we do instead .. . Answer : Does this make sense If it does is there some way around this problem If it does not why not and what should we do instead As prodigitalson said http : stackoverflow.com questions 7911270 how-does-one-setup-correlated-subversion-externals-should-one 7911304 7911304 already an external in SVN basically is considered a totally different piece of software with its own release cycles branches tags etc . According to this model you should not have unpinned externals into some trunk at all but have them all pinned to either a tag or a revision . That s a pretty restricted model of using code from external sources but that s what SVN supports . Stray from this and you are on your own . See below for my personal war story about that . Another thing I would reconsider if I was you is referring to a different repository . IME referring to an external relatively to the current project or repository root is much better than using absolute paths . Just consider the possibility that you might ever change the protocol from svn : to say https : . I have seen this happening to a company and despite heavily relying on scripting to change all the externals this transition was a mess everyone involved keeps having nightmares about . Relative paths to externals simply are more robust but they are only available within a single repository . .. . .. . The company I am working for has just faced a similar problem . We have a lot of code that is shared between different products . This is done via externals and those externally referenced projects have externals themselves . At some spots we re down to three layers of recursive externals and we already know that there will be more in the future . All that code is worked on constantly and we like to let externals reference the trunk of the projects they refer to because automatic testing takes the edge off that and managing releases of all those recursive externals would require efforts we simply cannot afford . But branching a project in this setting is a real pain in the erm neck because it s not enough to pin a project s externals when those themselves then refer to unpinned externals . Whenever you need to branch project foo to foo which via an external refers to project X which in turn via an external refers to project XX you would need an foo branch of XX which is an external in an foo branch of X which is an external of foo itself . Imagine half a dozen externals in foo half of which have their own externals some recursing three or even more layers and you reach the point where project XXX is littered with branches created for projects it shouldn t even know about . Our solution is to recursively either A replace all externals with a branch of what they referred to or B setup a branch of external X in foo branches externals foo X that s referenced by project branches foo with foo branches externals foo X itself referring to foo branches externals foo XX . However setting this up when creating foo is impossibly complex and offers more than enough chances for making silly mistakes so we employ scripting to recursively descent the project and its externals and do all that .", "Question : I m using VisualSVNServer . I ve a svn repo say : test1 with externals say : test2 . Everything fine so far when I checkout test1 test2 is automatically checked out to and placed inside my working copy of test1 . Good .

Within branches there are several dozen release branches e.g . 1.0 1.1 . These branches directories contain a relatively large application . I want to add an external at the root of repo called myExternal . When I define the external the only way to get SVN to create the myExternal directory is to run svn up from the root of repo . However this will also cause the entire contents of branches to be checked out which is unacceptable we have many developers that need to get myExternal added to their copy of repo and can t have all of them checking out gigabytes of unneeded branches . I ve tried svn up --set-depth immediates but that doesn t seem to get the externals . Is there any way to tell svn to fetch myExternal without fetching all of branches Using SVN 1.7 . .. .

Downside to a SVN external is that if it belongs-to a different repository then it is not possible to commit changes in both root working copy and external s WC in a single action .

Answer : The answer partially depends on the version of Subversion that you re using . Older versions could only do externals at the folder level but newer versions are capable of doing externals at the file level . Even if you are using the latest version I recommend doing your externals at the folder level anyway . You ll typically end up with a lot less maintenance work than if you have to update your externals metadata any time you add remove rename a file . In your specific case you could store all of the company-specific files in a folder named something like webresources services service1 jsp client and have Subversion populate that directory using svn : externals .", "Question : I m using bzr to access a Subversion repository .

Answer : As Dialecticus already commented there is no such thing as a shared folder or a shared file in Subversion . You can bring something else in your working copy using svn : externals but that doesn t really make it shared .

I am just trying to figure out a way to get the external that are specify in a transaction but cant figure out how . The command svnlook dont seem to be able to return anything that remotely look like externals modification . And with the svn command it seem to be the transaction that I am unable to specify . I have no idea what command to use in my pre-commit hook . I am currently in windows but making a python script to be able to test this on our linux server . What I tested so far is the following : .. . .. . In my repository C : TestReposLocal I have one external that is the trunk of another repository . This repository is displayed with the svn propget command but I need to know with the current transaction in a pre-commit if this external is something else than a Tag . Any help would be gladly receive . Tnx Comment : The real solution to your problem starts with getting rid of svn : exterals for the reasons you re encountering and more Comment : That would be difficult . We are a compagny and we each sector have a repository to put our stuff in them . We each have a version of our repository and are modified frequently . And our SDK is a melting pot of every part the compagny is working on . When we release a tag we tag every external and release a version containing only tags .

Comment : @thekbb - don t fix the things which are not broken And don t dictate policy for company which you don t own Comment : I m not dictating policy - just making the observation that svn : externals are very very rarely used in a way that makes things easier . Without knowing more it s hard to recommend an alternative.. . However the OP did mention an SDK it seems odd that the source of an SDK would be needed . .. . Answer : Well I can t see really your trouble-point here .. . .. . Any almost any operation in pre-commit hook with transaction and local repo can be performed with svnlook .. . svnlook have subcommand propget with can operate on transaction level and extract any property from any path inside repo transaction in this case and you must already know there you can meet externals inside repo-tree .. . you can identify correct needed format of externals from any previous revision inside repo .. . .. . Edit .. . .. . OK I see : additional details is needed here . For tests and experimenting I used open repository Proving Ground for externals on Assembla https : www.assembla.com code subversion-troubleshoot-b subversion nodes which have PEG-ed revision in tags and not PEG-ed in trunk . In order to use svnlook locally I just svnrdump ed it into local repository . Nearest equivalent to getting property from transaction is getting it from committed revision . Tag 1.0.1 was created with r7 .. . .. . where : .. . .. . 1 . rep is relative-path to repository on local filesystem .. . 2 . tags 1.0.1 is path inside repository for which I previously know that it should have definition .. . 3 . -r 7 is revision which I want to test .. . .. . Tag was created from trunk in which external is not binded to specific revision .. . .. . You ll have to see difference in specification now .. . .. . WARNING : format of externals-definition will be different in case of using ancient pre 1.4 SVN-clients and can be slightly different can t recall exact details in case of using CLI-version of SVN or SVN-integration from IDE definitions above I created with TortoiseSVN but it will be your part of job .. . .. . I order to apply business logic of hook only when it needed for commits in tags only and finish commits faster you have also check in hook at early stages additional condition - is this commit tag-related or not . It s again svnlook and dirs-changed subcommand .. . .. . dirs-changed for commit into tags .. . .. . dirs-changed for commit into other location .. . .. . you can grep tags in good OS do some tricks in Windows operate according to results .. . .. . PS : Don t forget replace -r with -t on production and store transaction-id+repo-path which you ll get as parameters for hook Comment : My problem is that I cant seem to figure out how to write the command-line properly for a transaction . In my above example I wrote : svnlook propget C : TestReposLocal svn : externals I was missing trunk at the end . This is to be able to validate a already existing path in the repository . What I am trying to do is to be able to see which externals are being commit in a transaction I guess the line should look like svnlook propget C : TestReposLocal svn : externals -t 12-2c or whatever the transaction number is .

Does Jackcess provide a JDBC driver for Microsoft Access databases .. . .. . Unfortunately no . The Jackcess API is a direct implementation of the features available for interacting with an Access database . There is currently no implementation of the JDBC API included with the Jackcess library . While this library would be a great foundation for a JDBC driver implementing the JDBC API is currently outside the scope of this project . There have been a few attempts to use Jackcess to build JDBC drivers for Access databases but most of the projects have not progressed very far before becoming inactive . The UCanAccess project http : ucanaccess.sourceforge.net site.html however is a currently active open-source project which provides a JDBC driver built on top of Jackcess .

On Jackcess Homepage there is only this Information with the link-to Bouncy Castle : The encryption support requires an additional library Bouncy Castle . Making this support separate from the main Jackcess library allows users to avoid including unnecessary libraries . I could not get any Information about dependencies or required compatible Versions . Comment : To clarify : You re talking about an Access 97 file that is protected with a database password .

If I open the file with msaccess user I only need to enter the username and have to leave password empty . .. . Answer : It turns out that while jackcess-encrypt is source compatible with bouncycastle 1.52 it is not binary compatible . See this feature request https : sourceforge.net p jackcessencrypt feature-requests 2 for more details . Basically for now you need to use a version of bouncycastle 1.50 or lower .

Comment : Yes you don t have to replace the correct jackcess jar 2.0.4 but remove the wrong one from your classpath . There couldn t be another cause of the exception you re getting you have another jackcess 1.x.x jar in your classpath or something dirty in your environment .

Do you have any further advice Comment : I was able to remove the older jackcess from the class path by creating a new JRE System Library but it still gives the same error . The only way I was able to resolve this was by manually removing the older file from its folder .

Here the answer by @Gord Thompson : unsupported collating sort order when trying to read from Access using Jackcess Java http : stackoverflow.com questions 20719417 unsupported-collating-sort-order-when-trying-to-read-from-access-using-jackces", "Question : I have a Jackcess table and everything is working just fine . BUT I can t find anything on how to change a column name in the Jackcess table . The reason I want to change the column name is that I have a ResultSet which is converted to Microsoft Access using Jackcess . a column is named RELATION but when Jackcess converts it the name is changed to xRelation . it must be some kind of Blacklisted word.. . I want to change the column name back to RELATION and changing RELATION itself to something else is not an option . How can I do this .. . Answer : Jackcess cannot alter the structure of the table after it has been created . So if you want that column to be named Relation instead of xRelation you will probably need to .. . .. . explicitly create the table first e.g . using TableBuilder with Relation as the column name and then .. . use ImportUtil.importResultSet to import into the table you created : .. . .. .

How can I implement the above Comment : Welcome to StackOverflow . Thanks and other chit-chat read help tour http : stackoverflow.com tour should never be included in a question . Comment : you should be able to do everything except the foreign key reference . at this point in time jackcess does not support creating foreign key indexes .", "Question : I have installed Jackcess 2.0.4 API on my Ubuntu 14.04 server IP : 192.168.0.130 . And now i want to access a Microsoft Access 2010 DB on a Windows 2003 R2 server IP : 192.168.0.125 . How do i do this .. . Answer : Jackcess will need to be able to open the database file so .. . .. . 1 . The database file will need to be in a shared folder on the Windows server and .. . .. . 2 . The Ubuntu server will have to be set up to mount the Windows share most likely using steps similar to those described here : .. . .. . MountWindowsSharesPermanently https : wiki.ubuntu.com MountWindowsSharesPermanently .. . .. . Once that s done Java code running on the Ubuntu server should be able to use Jackcess to manipulate the Access database file by opening it from the mounted location . For example if you ve configured the Ubuntu server to make the Windows share available at mnt windowsshare then Jackcess would simply open the database file in that folder : .. . .. . IMPORTANT NOTE : .. . .. . Jackcess reads and writes Access database files .accdb and .mdb files directly . It does not use the Access Database Engine ACE Jet and does not try to recreate the multi-user support that ACE Jet provides . Therefore Jackcess itself has no way of managing multiple concurrent users . Ref : here http : sourceforge.net p jackcess discussion 456474 thread 295b0032 limit 50 . If the Access database resides on a Windows share then there is at least the possibility that some other user or process might try to update the database while Jackcess has the file open . If that happens you could very well experience strange errors or perhaps even corruption of the database file .", "Question : I am using the Jackcess API with an Access database . I open the database and get a specific table . How can I get the data rows from this table which matches a list of ids For example get all the rows from the table where id is in List . In this particular case I want to delete the rows . .. . Answer : Jackcess provides very limited functionality for querying the data so your best option is to go through the table with an iterator or streams . Comment : yeah but what after this how can I write the query like for each row if id component id return it Comment : You don t know how to write an if clause and add to a list based on that Comment : My aim is to delete the data from the table and for that I need to write a delete query Comment : Why didn t you say so . You can t do that with Jackcess . You ll need to create a new table and leave the missing values out . Comment : You can t delete rows with Jackcess . - Actually you can delete rows using Jackcess .

And I perceived that Jackcess doesn t need password to access the database s data while UCanAccess only works if I insert the password if the database has . So wtf really happens If Jackcess is a dependency of UCanAccess why does it needs password Or why does Jackcess doesn t require password too Thanks Comment : wtf may be perceived as something unpolite.. . anyway if you really want to protect with a password your access file you have to encrypt it . If not just a code weak code based block will be applied by the upper layer API implementations MS Access via ODBC or GUI UCanAccess . .. . Answer : When a database password is assigned to an older-format .mdb database the file is not actually encrypted . Older versions of the MS Access application had a separate option to encrypt the file but even that protection was pretty weak . If the file is not encrypted then Jackcess does not require a password to open it . In fact Jackcess provides a way to retrieve the database password from an unencrypted but password protected .mdb file . As suggested in the comment to your question the UCanAccess development team decided to remain consistent with the other higher-level data-access methods and require that the user supply the correct password while opening the database . If you really wanted to avoid coding the database password into a UCanAccess application then you could always .. . .. . open the database file with Jackcess first .. . use Jackcess calls to retrieve the database password .. . close the Jackcess connection to the database and then .. . supply the database password when opening the UCanAccess connection to the database . Note that when applying a database password to a newer-format .accdb database the file really is encrypted so both Jackcess and UCanAccess require the correct password along with the additional component Jackcess Encrypt plus dependencies to open it .", "Question : I need help in a routine I ve written to dump the content of a class which represent a database-table to a new database-table in MS Access .

Comment : The issue was fixed in version 2.0.9 released today .", "Question : I am working with Jackcess to read and categorize an access database . It s simply meant to open the database loop through each line and print out individual row data to the console which meet certain conditions . It works fine except for when I try to read numeric values . My code is below . This code is built into a Swing GUI and gets executed when a jbutton is pressed . When the code is run I get the following error : .. . .. . java.lang.ClassCastException : java.lang.String cannot be cast to java.lang.Double .. . .. . The following condition looks to be what is throwing the error . row.getDouble CURRENTGAC 12.00 .. . .. . It appears that when the data is read from the database the program is reading everything as a string even though some fields are numeric . I was attempting to cast this field as a double but java doesn t seem to like that . I have tried using the Double.parseDouble and Double.valueOf commands to try converting the value as mentioned here http : stackoverflow.com questions 5769669 convert-string-to-double-in-java but without success . My question is how can I convert these fields to numeric values Is trying to type cast the way to go or is there a different method I m not aware of You will also notice in the code that I created a cursor but am not using it . The original plan was to use it for navigating through the database but I found some example code from the jackcess webpage and decided to use that instead . Not sure if that was the right move or not but it seemed like a simpler solution . Any help is much appreciated . Thanks . EDIT : .. . .. . To ensure the program was reading a string value from my database I input the following code .. . .. . row.get CURRENTGAC .getClass .getName .. . .. . The output was java.lang.String so this confirms that it is a string . As was suggested I changed the following code .. . .. . The ouput to the console from these changes is below .. . .. . 9.85 11.76 9.57 12.98 10.43 13.08 10.53 11.46 .. . This output although looks numeric is still of the string type . So when I tried to run it with my conditional statement which is commented out in the updated sample code I still get the same java.lang.ClassCastException error that I was getting before . Comment : You can easily see if Jackcess really is returning a string by printing row.get CURRENTGAC .getClass .getName and seeing if it says java.lang.String . If that is the case then have your application print String.format s row.getString CURRENTGAC and edit http : stackoverflow.com posts 30261961 edit your question to show us what it looks like . Comment : Apologies for the delay . My computer was having some security issues that were beyond the scope of this program but are now fixed . My edits are now posted . Thanks for your assistance . .. . Answer : Jackcess does not return all values as strings . It will retrieve the fields columns of a table as the appropriate Java type for that Access field type . For example with a test table named Table1 .. . .. . .. . .. . the following Java code .. . .. . .. . .. . produces : .. . .. . If you are unable to get Double.parseDouble to parse the string values from your database then either .. . .. . they contain funny characters that are not apparent from the samples you posted or .. . you re doing it wrong . Additional information re : your sample file .. . .. . Jackcess is returning CURRENTGAC as String because it is a Text field in the table : .. . .. .

Comment : Here is a sample http : wikisend.com download 544616 myDatabase.accdb of the database I am working with . I believe I was coding similarly to your example but I could still very well could be doing it wrong . That s pretty much the point for posting it to this forum . If you can find any additional funny characters please let me know how you found those also . Comment : @Rucker06 The CURRENTGAC string values are perfectly fine and parse correctly . I have update my answer . Comment : Thanks for the help . It works now .", "Question : So I have a program that selects a DB and exports it as a csv . It appears when I export the DB the tab delimitation does not keep any data types . The csv ideally should keep text fields as instead of just . Although the fields are numbers they have no need to be treated as numbers . This lack of formatting causes a small issue with sorting and I can see jackcess supports data types but will I need to use the cursor to keep these datatypes or can I still use the exportFile function Comment : What do you mean by a small issue with sorting True Jackcess does not put text delimiters around every text field only the ones that contain commas but many other applications export to CSV that way . And Jackcess does not do silly things like removing leading zeros from text fields that look like numbers . Comment : The output from my program puts the first account 0 as the 10th account and everything else besides the first ten are in perfect order . So is there a way with Jackcess to output my alphanumberic fields with the around every field or should I consider something else I just read in the documentation that Jackcess supports the text datatype but does the export keep the datatype in .csv format Comment : 1 What is the field type of the field on which you want to order the results 2 Does that field have an index on it Comment : The field does not have an index and it is alphanumeric but for my purposes every field could be treated as text so long as the first field is sorted ascending alphanumerically . .. . Answer : I m not aware of a way to force Jackcess to enclose all text fields in double quotes when exporting . However that would not affect the order in which the rows are exported by Jackcess anyway . When using exportFile http : jackcess.sourceforge.net apidocs com healthmarketscience jackcess util ExportUtil.html exportFile com.healthmarketscience.jackcess.Database 20java.lang.String 20java.io.File Jackcess will export the rows in natural order which is the order in which the rows physically exist in the table often but not always the order in which the rows were inserted into the table . When using exportWriter with a Cursor http : jackcess.sourceforge.net apidocs com healthmarketscience jackcess util ExportUtil.html exportWriter com.healthmarketscience.jackcess.Cursor 20java.io.BufferedWriter 20boolean 20java.lang.String 20char 20com.healthmarketscience.jackcess.util.ExportFilter Jackcess will export the rows in the order defined by the Cursor . So if the field on which you want to sort the output has an index on it then you can create an IndexCursor and use exportWriter with that Cursor to dump the rows to CSV . If the field on which you want to sort the output does not have an index on it and you are unable or unwilling to create such an index in the Access database then another approach would be to use the UCanAccess http : ucanaccess.sourceforge.net site.html JDBC driver to create a ResultSet based on an SQL statement that has an ORDER BY clause then use something like opencsv http : opencsv.sourceforge.net to dump the ResultSet to CSV . Comment : Thank you . I needed to use the Cursor and to solve the issue of string values I just have another function with some regex that puts before and after commas . Maybe not the most efficient but I just need it to work and it does in less than a second so I cant complain .", "Question : I am not much familiar with Java but I try to accomplish this task in R my fav There is this Java library called Jackcess http : jackcess.sourceforge.net .

I only get an additional separate Stacks graph . It s ok but not where I d expect it i.e . in the Generic Events window . My question was related to Generic Events in general not only to user mode providers . Maybe other kernel flags do not have corresponding user mode provider do they so it s not clear for me yet.In addition if I do it this way symbols are missing again . Do we have to add a minimum set of providers to get symbol support Comment : generic events user mode events . Click on Open View Editor and activate he stack column here . symbols are missing because NETWORKTRACE is not enough . Use NETWORK which captures PROC THREAD+LOADER both MUST be used all the time Comment : Sorry but this is not right because networktrace is a kernel flag and the events are shown in the generic events graph . Anyway I ll just have to accept but not understand that there s no Stack column in that graph . Regarding symbols I found out meanwhile too thanks . Comment : there are stacks if you activate them . I use this often . But for network there is no stack option . Here you have to activate the usermode providers that I told you .

Comment : If Visual Studio was perfect then who would buy Resharper", "Question : How do you extend Tabs in Visual Studio 2013 It would be handy to extend the Tabs so that you can selectively track an item in Solution Explorer by right clicking on a tab . By default Visual Studio will track active items in Solution Explorer via the setting : Tools Options Projects and Solutions General Track Active Item in Solution Explorer . Having that turned on makes Solution Explorer jump around and is consequently confusing on large projects so I turn it off . But what I d like to be able to do is right-click on an open tab and select a menu item to make Solution Explorer track and display that file s location in Solution Explorer .

Answer : The type returned by Worker.Malloc is DeviceMemory this represents one memory allocation on Gpu . It is disposable so you can dispose it yourself or let GC to clean it . But note if you rely on GC to collect there is delay it is done in a GC thread and since Gpu memory is all pinned memory cannot be swapped to disk so it is recommended that you dispose it explicitly . To make code easier you can use C using keyword . Of course Alea Gpu works with those types the problem you met is because you need specify the exact type . Note a 1.0 is of type double and 1.0f is of type single . The reason is the kernel function is provided to worker launch method by delegate so you need specify the correct data type to help it to find the kernel method .

Answer : I m no expert on GPU programming but have a basic understanding . I saw this question while evaluating Alea GPU . The NVidia GTX 980 Ti has 2816 cores . With a blockSize of 256 that gives a grid size of 2816 256 11 . The Alea Community Basic Developer library allows up to 2688 cores . If the Alea library sets a blockSize of 256 this is a guess that gives a gridSize of 10.5 . Could it be that the job is being split into two The first run saturating the 2688 core limit and then the rest running on 2816 - 2688 128 cores", "Question : Having done some work implementing various ML algorithms in Alea I ve tried benchmarking some simple but essential routines in Alea . It surprised me to find out that Alea takes roughly 3x longer than the equivalent cuBLAS call to sgeam do the same thing . If I was doing something more complex like matrix-multiplication where I had to juggle shared-memory this would ve been understandable but the following are just simple array transformations . DeviceUnaryTransformModule transform module s kernel is the same as from the basic transform example the only difference is that afterwards instead of gathering to host it keeps the data on the device . Also the Unbound s reduce works really poorly for me so badly in fact that there must be an error in the way I ve been using it . It is roughly 20x slower than using sgeamv twice to sum a matrix . I haven t tried comparing this with CUDA C++ but for simple things I think it should be on par with cuBLAS . I thought that the optimization flag might have been off but then found it was on by default . Any optimization tips I am missing here .. . Answer : I think there are some issues in your testing code : .. . .. . 1 . In your mapping module you should preload the GPUModule . GPUModule is JIT-compiled when the first time it is launched . So actually your timing measument includes the GPU code compiling time .. . .. . 2 . In your mapping module both Alea code and the cublas code you should sync the worker sync the CUDA context . The CUDA programming is async style . So when you launch the kernel it returns immediately without waiting for the kernel to complete . If you don t sync the worker actually you are measuring the kernel launching time not the kernel executing time . Which Alea gpu s launching time will be slower than native C code since it will do some marshaling of the kernel arguments . There are some other issues related to the kernel launching time which I will show you in following example code . 3 . Your reduce test actually load the reduce module each time which means each time you do reduction you measures the time including the GPU compiling time It is suggested that you make the instance of GPU module or Program to be long lived since they represent the compiled GPU code . So I did a test following your usage . Here I first list the full test code : .. . .. . In Alea GPU a worker represents a CUDA context and currently we are using the pattern that one GPU uses one dedicated thread and on that thread the CUDA context is attached . We call this worker with dedicated thread . So this also means each time you call a CUDA API such as kernel launching we have to switch to the worker thread . If you are doing a lot of kernel launching it is suggest to use Worker.Eval function to execute your code inside the worker thread to avoid thread switching . There is also an experimental feature of creating worker on current thread which thus avoid the thread switching but we are still optimize this usage . For more detail please reference here http : quantalea.com static app manual programming gpus-device and worker.html .. . .. . Now we first use the default worker to do a test without sync the worker thus it means we are comparing the kernel launching time only . The default worker is a worker with dedicated thread so you can see it performances better when we use Worker.Eval . But overall kernel launching from .net is slower than the native C kernel launching : .. . .. . Also you might noticed I run this test twice and in the first time the test without pre-loaded module uses 304 ms but in the second time the test without pre-loaded module uses only 29 ms . The reason is we use LLVM P Invoke to compile the kernel . And those P Invoke function are lazy function so they have some initialization when you first use it after that it becomes faster . Now we sync the worker which actually measured the real kernel executing time now they are similar . The kernel I created here is very simple but it does op on both matrix A and B : .. . .. . Now if we test them on threadless worker they will be a little bit fast since there is no thread-switching : .. . .. . Now here is test over reduce : .. . .. . Please note in this reduction test there are one memory gathering memcpyDtoH for each reduction to get the result from device to host . and this memory copy API calling automatically sync the worker because if the kernel isn t finished the value is meaningless . So if you want to compare the performance with C code you should also copy the result scalar from device to host . although it is just one CUDA api invoking but as you did it for many iterations 100 in this example it will acuumulate some timing there . Hope this answeres your question . Comment : BTW the current alea gpu uses nvidia llvm compiler from CUDA 6.0 . We will release a new version which upgrade it to CUDA 7.5 when CUDA 7.5 is released . From what I observed now this upgrading increased the performance of generated kernel . Comment : This is a great answer . I actually knew that CUDA had asynchronous lauches by default in C++ but I assumed that it was different in Alea . That was because I did not know that asychronous kernel execution acts a bit like lazy-evaluation in functional languages . I thought it was something else .

Alea GPU s random module is designed follow the SPRNG library sprng.org http : www.sprng.org . Comment : Thanks . I never head about the SPRNG library before . Also this would be a good time to ask just how expensive are these streams in terms of memory and computation Comment : the idea is say you want 1M random numbers and you don t want create GPU memory for 1M numbers . So one solution could be you use 2 streams : let rng RandomModule.Create streams 2 seed time then rng.AllocCUDAStreamBuffer will allocate memory fo 0.5M numbers . Then you rng.Fill streamId 0 buffer . It will fill the buffer with the first 0.5M numbers . set streamId 1 fills the next 0.5M numbers .

In the other question the error was about not able to load find 4.3.1.0 whereas what I am getting is related to AOTCompilerServer exiting unexpectedly . When I tried to clean build only the fsharp project I am not interested in the csharp one at the moment I got the following error : .. . .. .

Answer : The error means that cucumber.runtime.RuntimeOptions has no constructor which takes a List as argument . Since all classes are part of cucumber I suspect a bug in the release . Run mvn dependency : tree and search the output for cucumber . Make sure that you have only a single version of the dependency . If your classpath is good try an older version .

Answer : I m trying to get a Save dialog box to pop-up and prompt the user what location they would like to save a particular file to after they hit an API route .

Whenever i get to the same API route but go through my TypeScripted front-end UI i can t get the same prompt to pop-up . What s the deal Comment : When you go through the browser directly it interprets the Content-Disposition header automatically and prompts you to save the file by design .

Answer : I ve got a Shiny app that produces a product that I d like my users to be able to save in whatever location they d like to save it and with whatever name they d like . In order to do this I m currently using file.choose to allow the user to choose a location and file name . On Windows if it s a new file the user will be prompted with a message saying this file does not exist and asks if it should be created . On Ubuntu I believe it was the same outcome . However this option doesn t work on Mac as there s no way to enter in a new file name and an existing file must be chosen . Additionally the dialog box says Open as opposed to Save which is confusing to some users . Is there a way to trigger the Save As dialog box that opens when you save a new file save write and all other functions either come with a predefined file name or expect one to be passed .

I ve come across some questions on SO that attempt to address this with the tcltk package but I m not sure I like this solution since there seem to be some issues on Mac OSX with this package .

And i want to store local file @server with perticular url Comment : what is the error .. . Answer : The getInputStream method of the uploaded file represents the file content . You need to copy it to a file . You should first prepare a folder on the local disk file system where the uploaded files should be stored . For example path to uploads on Windows that would be on the same disk as where the server runs . Note that you should absolutely not store the files in expanded WAR folder by using a relative-path or getRealPath for the reasons mentioned here Uploaded image only available after refreshing the page http : stackoverflow.com questions 8885201 uploaded-image-only-available-after-refreshing-the-page . Then you need to autogenerate the filename . Otherwise when someone else uploads a file with coincidentally the same name later it would be overwritten . You could use Files createTempFile http : docs.oracle.com javase 8 docs api java nio file Files.html createTempFile-java.nio.file.Path-java.lang.String-java.lang.String-java.nio.file.attribute.FileAttribute...- facility to get an autogenerated filename .

I just need to figure how to save from the memory . Comment : Do you only load the images to memory or do you also show them in a UI If you don t show them there is no need to create BitmapImages you could simply store the binary file content as byte array . Anyway saving a BitmapImage to file is done by a BitmapEncoder e.g . a PngBitmapEncoder . Comment : I ll take a look into that . And yes I show the images in the UI . .. .

Answer : The MP3 class is a type of ID3 class which as the tutorial says is highly structured http : mutagen.readthedocs.org en latest tutorial.html hard-examples-id3 and cannot be simply written to because of metadata it needs to keep track of . I suspect that s the reason for the errors -- when you re trying to save or print the audio object the code is expecting each key to point to some object but instead sees a simple string . Instead you need to specify that you want to use the EasyMP3 class so you can edit the keys like you want . The EasyMP3 class will automatically convert the strings into the appropriate objects for you . Example from the docs : .. . .. . However you can only edit certain keys . To get a list of valid keys that are editable use the following : .. . .. . Edit : .. . .. . Disclaimer : None of this is tested and might need tweaking or debugging . To edit tags not included within EasyMP3 you could reference this chart http : help.mp3tag.de main tags.html and use the 4-letter tag under the ID3v2.3 column .

Comment : I get a lot of images it s first displayed then I want to save all of them . so I should name them firstly then set a path to store them finally the script can save them automatically when I use the script . Comment : @user1438038 thank you I should provide my codes . .. . Answer : The script you ve written will not save anything but most likely produce an error . In the For -loop you 1000000x get the next image to save but when you reach the end the next image is invalid . Therefore the next iteration will throw an error at img.SetName because img is not a valid image at that moment . What you want to do is something like the following :" ] }

Answer : Sqoop and Flume both are meant to fulfill data ingestion needs but they serve different purposes . Apache Flume works well for streaming data sources that are generated continuously in hadoop environment such as log files from multiple servers whereas whereas Apache Sqoop works well with any RDBMS has JDBC connectivity . Sqoop is actually meant for bulk data transfers between hadoop and any other structured-data stores . Flume collects log data from many sources aggregating it and writing it to HDFS .

My confusion is because big data architecture i am looking at which i have no virtual copy of grouped structured-data and its transferred by Sqoop and Unstructured streamed by Flume .

Answer : sqoop is essentially a tool to ingest data in HDFS from RDBMS . Under the hood it generates simple Java code which submit a query to a RDBMS and writes the result to HDFS . This means that you can import with sqoop everything which can be accessed via JDBC connection and which has a Java driver available . For this reason you can t use it for files like logs or things like that . Then sqoop can t handle video or audio files . Flume instead is used to monitor and ingesting in real-time informations .

Answer : It is common for Hadoop services to look for jars in HDFS because all nodes in the cluster can access files in HDFS . This is important if the MapReduce job being kicked off by the Hadoop service in this case Sqoop has a dependence on those jars . Remember the Mappers are running on a DataNode not the NameNode even though you are probably running the Sqoop command from the NameNode . Putting the jars on HDFS is not the only possible solution to this problem but it is a sensible one . Now we can deal with the actual error . At least one but probably all of your Mappers are unable to find a jar they need . That means that either the jar does not exist or the user trying to access them does not have the required permissions . First check if the file-exists by running hadoop fs -ls home SqoopUser sqoop-1.4.3-cdh4.4.0 sqoop-1.4.3-cdh4.4.0.jar by a user with superuser privileges on the cluster . If it does not exist put it there with hadoop fs -put jarLocationOn NameNode fileSystem sqoop-1.4.3-cdh4.4.0.jar home SqoopUser sqoop-1.4.3-cdh4.4.0 sqoop-1.4.3-cdh4.4.0.jar . I haven t worked with Cloudera specifically so you will have to track down the jar location on the NameNode yourself . If Cloudera is anything like Hortonworks there will be occasional issues like this where cluster deployment scripts documentation misses a couple of required steps to get everything up and running . Now that we know the file-exists we can check to see if the user SqoopUser has permissions to the file . Again run hadoop fs -ls home SqoopUser sqoop-1.4.3-cdh4.4.0 sqoop-1.4.3-cdh4.4.0.jar and look at the file-permissions . Also check the permissions of the directories containing the jar . Explaining POSIX file-permissions is outside the scope of this answer so if you are not familiar you might need to read up on those . One important note is that HDFS does not have its own concept of groups it bases that on the groups of the underlying OS . Just make sure the jar is readable by SqoopUser and all of the parent directories are executable by SqoopUser . Indiscriminate user of chmod 777 will take of this ie hadoop fs -chmod 777 home SqoopUser sqoop-1.4.3-cdh4.4.0 sqoop-1.4.3-cdh4.4.0.jar . But of course be more discerning about the permissions you grant if your environment requires it . If you find file-permissions are tripping you up more often than you would like the nuclear option is to set dfs.permissions to false in hdfs-site.xml . This will let all users access all files on HDFS . This can be very useful for rapid development but it is safer to leave dfs.permisssions on .", "Question : I am using cloudera CDH for practising sqoop .

I am trying to copy the tables to hive database Then why an existing file in cloudera caused the problem . Is there a way to ignore this error or overwrite the existing file . .. . Answer : This is how sqoop imports job works : .. . .. . sqoop creates imports data in tmp dir HDFS which is user s home dir in your case it is user cloudera . Then copy data to its actual hive location i.e . user hive wearhouse . This categories dir should have exist before you ran import statements . so delete that dir or rename it if its important . hadoop fs -rmr user cloudera categories .. . .. . OR .. . .. . hadoop fs -mv user cloudera categories user cloudera categories 1 .. . .. . and re-run sqoop command So in short Importing to Hive will use hdfs as the staging place and sqoop deletes staging dir user cloudera categories after copying sucessfully to actual hdfs location - it is last stage of sqoop job to clean up staging tmp files - so if you try to list the tmp staging dir you won t find it . After successful import : hadoop fs -ls user cloudera categories - dir will not be there .", "Question : I have 3 physical nodes running DSE 4.5 . On the same 3 nodes I have HDP 2.2 running as well .

My confusion is because big data architecture i am looking at which i have no virtual copy of grouped structured-data and its transferred by Sqoop and Unstructured streamed by Flume . My question regard that is does that mean Flume is only for streaming What about high frequency data and does Flume support transfer of unstructured data that are non-log files i.e . audio video or would Sqoop be able to handle that Final question is can Sqoop work with federated data sources if yes with both real and virtual Thanks .. . Answer : Apache Flume is a distributed reliable and available system for efficiently collecting aggregating and moving large amounts of log data from many different sources to a centralized data store . The use of Apache Flume is not only restricted to log data aggregation . Since data sources are customizable Flume can be used to transport massive quantities of event data including but not limited to network traffic data social-media-generated data email messages and pretty much any data source possible . .. . .. . .. . .. . Apache Sqoop is a tool designed for efficiently transferring bulk data between Apache Hadoop and structured datastores such as relational databases it imports data transform the data in Hadoop MapReduce and then export the data . Sqoop automates most of this process relying on the database to describe the schema for the data to be imported .

I know authentication login creating accounts etc . But now I want to work on groups and permissions . Where is the documentation for django groups permissions This is not it : http : docs.djangoproject.com en dev topics auth .. . Answer : I suppose the first question you need to ask are what permissions do you need and what sort . By what sort I mean do you want Model- or Object-level . To clarify the difference say you have a model Car . If you want to give permissions on all cars then Model-level is appropriate but if you want to give permissions on a per-car basis you want Object-level . You may need both and this isn t a problem as we ll see . For Model permissions Django handles these for you.. . mostly . For each model Django will create permissions in the form appname.permissionname modelname . If you have an app called drivers with the Car model then one permission would be drivers.delete car . The permissions that Django automatically creates will be create change and delete . For some strange reason they decided not to include read permissions from CRUD you will have to do this yourself . Note that Django decided to change CRUD s update to change for some reason . To add more permissions to a model say read permissions you use the Meta class : .. . .. . Note that permissions is a set of tuples where the tuple items are the permission as described above and a description of that permission . You don t have to follow the permname modelname convention but I usually stick with it . Finally to check permissions you can use has perm : .. . .. . Where obj is either a User or Group instance . I think it is simpler to write a function for this : .. . .. . Where entity is the object to check permissions on Group or User model is the instance of a model perms is a list of permissions as strings to check e.g . read change and app is the application name as a string . To do the same check as has perm above you d call something like this : .. . .. . If you need to use object or row permissions they mean the same thing then Django can t really help you by itself . The nice thing is that you can use both model and object permissions side-by-side . If you want object permissions you ll have to either write your own http : djangoadvent.com 1.2 object-permissions if using 1.2+ or find a project someone else has written one I like is django-objectpermissions https : github.com callowayproject django-objectpermissions from washingtontimes . Comment : This is a great answer for permissions but barely touches groups and how they work in Django Comment : There isn t a whole lot to groups they re mostly just for bundling users together to apply permissions much like Linux user groups .

It provides a way to assign permissions to specific users and groups of users . Like this app lable.model name . It may be convenient for the django-admin but I think it will be use difficult when I use it to control what people can to do with it . For example If I want to control whether a certain user can post a comment or see some portion content of my site . I have to config a permission group to him but why not just add a user property like can post or can view certain portion Its seems more intuitive . So who can help me understand those things Thanks in advance . .. . Answer : The reason to keep permissions in a separate model is to leverage groups . So if you needed to change the permissions on many users at once you could simply update the permissions of the group they are assigned to . Also since users can belong to more than one group you have more flexibility for customizating permissions per user . Keep in mind vanilla django-permissions are model based so if you need to limit changing only certain fields to different users you will need something more robust like django-guardian .", "Question : Is there a way to do row level permissions in django I thought there wasn t but just noticed this in the docs : .. . .. .

Answer : Why not mix both approaches in Django model allows for inheritence https : docs.djangoproject.com en dev topics db models model-inheritance . First define the Role model with allowed roles and a school model . You can then inherit a new model from django.contrib.auth.Group say GroupRole . Django will create a new db table for your model only containing the properties not originally in group with a foreignkey to the appropriate group with constraints . Even better you will get an automatic reverse relationship to the original group model so you can write something like : .. . .. .

Guardian needs attach detaching permissions though the rest of the code . Comment : I don t really understand what you mean by runtime vs object creation . Presumably they both use the database to store permissions and they both use an API to retrieve them . Comment : @RobertGrant : I added a couple of examples for clarity .

Answer : Django has a really nice authentication authorisation api built-in .. . .. . I would advise that you read the follow doc : https : docs.djangoproject.com en dev topics auth this gives you the basics . For your application the best way is to setup permissions for cetain things like permissions to edit courses .

For example if you had a view : .. . .. . you can add the above this view : .. . .. . and then only a user that has this permission can access that piece of functionality . YOu can the go further by creating groups that you can assign permission to e.g . a teacher group and then you can assign all of you staff to this group and they will inherit this course editor permission .

Answer : I am completely lost and am hoping to get some clarity . The Django documentation especially docs.djangoproject.com and djangobook.com talks extensively about how to retrieve permissions programmatically and to test users for permissions but what I can t find is one of the most basic uses of permissions alluded to in the documentation : controlling per-model not per-object just the model permissions for the admin interface . Say I have a model called Book . I want all staff users to be able to edit any book object in the admin interface . As an added layer of complexity I m using Django-nonrel with djangotoolbox and django-permission-backend-nonrel . I have created a permission called change book for the book type using the Permissions section of the admin interface . However my test user who is is staff but not is superuser just sees the generic message You don t have permissions to edit anything in the admin landing page . I can see the box to set unset permissions for the user but when I select the new permissions and click save the permission is not attached to the user as far as I can tell . What do I specifically name the permission and how do I attach it to the user UPDATE : Here s the relevant parts of settings.py : Comment : can you show your settings.py Especially the AUTHENTICATION BACKENDS part Comment : I ve added the parts of settings.py that are related to authentication and the user model .", "Question : I am looking for the best way to implement user-permissions to allow users to edit specific model instances .

We have GP and eConnect installed in a server.Our application runs from another machine which has to send data to GP in our server using eConnect . Is that necessary to install eConnect in developer s machine as well as in the server As eConnect uses windows-authentication we use integrated security in our application to connect with eConnect . So we are now able to integrate data from one user s machine whose credentials was given while installing eConnect in server . Can anyone help .. . Answer : In short yes . The eConnect SDK must be installed on every client machine that issues eConnect for requests . If you are building a web application then you would need the eConnect SDK installed on the webserver from which the requests originate . If you are developing windows forms application to be installed on each users PC then the eConnect SDK must also be installed on each users PC . Because this is often not a desirable deployment scenario many people are in the practice of creating a new service to encapsulate the specific eConnect requests that the application needs so that the SDK only needs to be installed on the server . Another option worth considering is a separate installation for Dynamics GP called the Dynamics GP Web Services . That would allow you to issue web service requests without the need of installing the eConnect SDK . However installing Web Services for Dynamics GP is not trivial . Regarding security the eConnect SDK creates a windows service where credentials are supplied . It is these credentials that are used to authenticate eConnect to Dynamics GP . Keep in mind that Dynamics GP does not support Active Directory authentication for user access . However one can use a domain service account in the eConnect service and set that up for access directly in SQL Server with DYNGRP role . Normally this account would be a service account created for this purpose and not the user account . Comment : We have a service account which has access to SQL with DYNGRP role in the server . Do we need to use the same credentials to invoke the service in the server from another machine Comment : As eConnect uses windows-authentication we use integrated security in our application to connect with eConnect . So we are now able to integrate data from one user s machine whose credentials was given while installing eConnect in server.But we need to integrate data from different machines different windows id by invoking service in the server . Comment : You will need to put the service account into the eConnect service . Don t use a user s credentials in the service account . As long as the eConnect account has DYNGRP role permissions in SQL Server it should function properly with any other valid active-directory account on each machine . Use the same eConnect service account on all machine installations .

Each time I need to repair the econnect to get rid of this exception . Any solutions", "Question : We are using Integration Manager to create a batch of monthly invoices . I want to build a replacement that creates a batch in GP and imports the invoices into the batch . After review the batch will be posted to GP . Is this doable with either of these API s and which would you choose .. . Answer : Integration manager can use econnect for its insertion engine . If you are processing a high volume of transactions you will notice a huge difference between integration manager s UI engine and econnect . When you create a new integration simply choose the econnect option and whatever data source you have set up . Concerning the non-IM APIs both may be used and they are situational . The web-services sits on top of econnect and it is much slower integrating because you are passing information between several layers . It does provide a secure link between your SQL server and any outside integration sources and it is ideal if you need to setup something to allow integrations to happen through middleware such as a billing gateway . If you have access to build an econnect process app that makes a connection to your SQL server for GP this is the fastest way to integrate SOP and receivable transactions . It maintains all the business-rules to help ensure GP does not break in as a result-of a patch and the speed is fast enough to push thousands of records without requiring a custom integration solution . If you want to get done quickly and do not mind working from the integration manager interface just build your integrations using econnect . If you have the time to develop a custom integration routine go for econnect . If you want to leverage WCF technology on top of econnect go for web-services .

I have a vague recollection that this approval happens in a workflow whose functionality was added somewhat recently in GP s history . So perhaps a second question is this approval functionality part of the stock Dynamics GP install or no Thanks .. . Answer : You can add purchase order approval functionality to Dynamics GP by enabling the option in the Purchase Order Enhancements Setup window . Microsoft Dynamics GP menu - Tools - Setup - Purchasing - Purchase Order Enhancements .. . .. . Refer to the manual for Purchase Order Enhancements from your installation media or download it directly from Microsoft . In a nutshell it allows you to set up security around approvals with limits on dollar amounts and restrictions by purchase order number vendor or created by . There is no eConnect integration to approve purchase orders but you may create your own process by extending eConnect with custom SQL logic . If you are unfamiliar with the database-schema in Dynamics GP you may want to reach out to a Dynamics GP Partner for assistance with that development .

Answer : Yes you are correct in order for your windows form app to work with the eConnect code you will need to install it on each of the clients .

Answer : You don t have to use SQL you can use eConnectOut to retrieve data but the result sets are somewhat limited out of the box . In the end I found that just dealing with SQL was easier for me because eConnectOut doesn t give you access to all of the GP data without manipulation to the eConnect Out Setup table which is cumbersome at best .

Answer : Actually you can setup econnect on the server and add a HTTP reference in addition to the net pipe . this will allow econnect to be called from a client that does not have econnect .", "Question : How do I get the next BACHNUMB for the Dynamics GP eConnect proc taPopRcptHdrInsert .. .

I have worked with Dynamics CRM before but not with Great Plains . I have heard that GP is a different animal than CRM even though they share the same Dynamics prefix where do the similarities end and where do the differences begin Has anyone had any experience with both Are you able to describe some similarities and or differences between the two Any caveats difficult parts or pain points I should be looking out for in GP I am interested about the entrance points into the product and ease of extending the user-interface . When I worked with Dynamics CRM I used a provided Web Service as the entrance point into the application . I read that GP has some sort of web service too but I ve also read that it supports something called eConnect new to me . That s a lot of questions I put in here I m not looking for a specific answer for every single point just wanted to get you thinking about the kind of information I am digging for . Thanks .. . Answer : Here is what I ve found working with these two products : .. . .. . They are very different products that were acquired by Microsoft in separate acquistions . CRM uses a web UI GP uses a fat windows client . Both have web service APIs but you ll find a lot less documentation and samples for GP . GP also has an API called eConnect but the web service API is a lot easier to work with . CRM customizations make it pretty easy to extend both the data model and the user-interface . It s mostly just point and click unless you need more sophisticated UI functionality using Javascript . The GP UI is called Dexterity which does support customizations . However I ve not had any experience with it .", "Question : Is there a way to get a list of existing credit cards in GP using eConnect Current implementation uses the .NET serialization approach mentioned in the eConnect documentation though I haven t been able to find any information about how to get a list of currently existing credit cards .

Am I out of luck on this one .. . Answer : GP doesn t and shouldn t keep credit-card numbers PCI compliance and all . The default info that is kept around is Card Name Reciept Number Auth code etc but not the card number itself Your best bet is to take a look SOP10103 http : www.gptablereference.com 2010 Table SOP10103 Comment : I see that the table stores all of the information that I m hoping to get a hold of but haven t been able to find any eConnect requests that I can build out to get that data . Is a direct SQL query the only way to get it Comment : Yes as of this time there is no eConnect request to retrieve this information . Direct SQL query is the recommended approach . If you want to keep all integration points going through eConnect in order to keep your architecture consistent consider extended eConnect to add the credit-card information request .", "Question : Simply trying to create via eConnect the EFT Bank informations on a customer .

In case someone reads this I ll give you a few sources after my question so you can guide your self even if this post doesn t help you . My question is how can I create a new PMClassMaster through C In the end its an XML file that you need to generate but I wonder if there is a method that does that for me For example to create a new Vendor you can do the following : .. . .. . This will pretty much create an XML for you because thats what GP recevies through eConnect s CreateEntity and UpdateEntity methods .

Answer : There is no eConnect node for the PM Class Master . Not everything that can be done in GP can be done via eConnect . For this you will have to manually insert records into the relevant SQL table in the desired database .", "Question : I was using eConnect to connect my .NET application to the Dynamics GP .

When using the fuctionnal currency everything works fine . The problem is that when I use another currency the ACCRUED REVENUES are set to 0 . I tried to enter the same entry manually in GP and the accrued revenues are OK . When you take a look at it in the UI everything is the same in both timesheet entryes . I specifed the currency id which is different from the functionnal currency and I provide a PAUNITCOST as requested by eConnect . If I look into the PA10001 TABLE there are differences between the record inserted manually and the one inserted with eConnect as the value of PA Base Billing Rate and PAORIGBSBILLRTE are set to 0 . The ACCRUED REVENUE COLUMN is evidently different as well . There is no option in taPATimeSheetLineInsert that can help me so I don t know what to do to make it work Please help .. . Answer : Just to let you know we resolved the problem temporarily and I would hate to find an unanswered post about that problem if I were to be someone else having the same problem . The problem with the econnect storedproc taPATimeSheetLineInsert is that it does thing differently than the timesheet entry inside GP . Looks like it tries to use the forecast profit amount instead of the profit amount set in the Project Budget . Funny that there is no usable data in the Forecast and that the stored procedure tries to get it anyway . For now we added a bit of code to get the paprofitamt instead of paforecastbaseprofitamt . Still have no clue about why the code was made like that but everything works fine . Have fun people" ] }

I just bought a Raspberry Pi and would like to reach it from the outside too preferrably with another subdomain . Can I use multiple CNAME records pointing at the DynDNS domain and then put a VHOSTS file in the servers to direct traffic to the right server depending on the subdomain called Or is it the DynDNS subdomain that calls the server rather than my own subdomain i.e . showing the same id to the server independent of the subdomain called by the user I d rather not use different ports for different servers handling the same protocol . Today : .. . server.example.com - CNAME - server.dyndns.com - 1.2.3.4 - home server .. . .. . Future : .. . server.example.com - CNAME - server.dyndns.com - 1.2.3.4 - home server .. . rpi.example.com - CNAME - server.dyndns.com - 1.2.3.4 - raspberry-pi Comment : That certainly is possible . from a technical point of view . But DynDNS does not offer usage of second level domains like that . Most likely you have an account there resolving to something like myserver.dyndns.org . Then you can use rpi.myserver.dyndns.org as virtual host . What you cannot do is have such subdomains resolve to different internal ip addresses since that would mean that the router would have to evaluate the host header inside the http protocol which does not work . Comment : I dont intend to use second level subdomains with my DynDNS address I want to direct several first level subdomains to my single IP and then split them to different servers . My intention is to have the VHOSTS file resolve which server to use if the host header contains my own subdomain name rather than just the DynDNS name which is what my question is all about . Comment : Ok no problem then . But what is the problem in this case Comment : I want to know if the host header shows my subdomain name rather than the DynDNS name . If so I can use VHOSTS to separate traffic to different servers . Comment : Perfect thats just what I wanted to hear .. . Answer : Ya I think you would just use CNAME records to point all of your sub domains to the same dyndns sub domain and then handle differentiating them all with vhosts . As for your raspberry-pi you might have to have a vhost on your apache web server that would act like a proxy server sending all traffic from a hostname sub domain to the pi s ip .

I just did this and it solved hours of head-scratching . On CentOS you can check your available vhosts with httpd -S Comment : I have voted to re-open this question because both the question and the answer are helpful . Besides this questions about Apache are not off-topic on StackOverflow and ServerFault is only for professional setups . .. . Answer : Sounds like you need to add NameVirtualHost directive http : httpd.apache.org docs 2.2 mod core.html namevirtualhost to your configuration . Under some circumstances Apache may not be able to handle : 80 VirtualHosts correctly . In those cases you should map VirtualHosts directly on specific IPs . You can also run apachectl -t -D DUMP VHOSTS to see how Apache parses the VirtualHost configuration . Update : As mentioned in the comments usually you can just use NameVirtualHost : 80 . So most of the time you can configure the virtual-hosts as follows . Comment : Thx Ketola . At the end of my httpd.conf file I have the following where the vhosts are included NameVirtualHost : 80 new line Include etc httpd sites-enabled Comment : That should work then . Apache can be a bit picky with : 80 at times so you might want to try 8.8.8.8 : 80 instead to see if it works better . Also run apachectl -t -D DUMP VHOSTS to see how Apache parses your configuration-files . Updated the answer to reflect these as well . Comment : Thanks Ketola tried that in both .conf files and the httpd.conf file but no cigar although the order changes The apachectl -t -D DUMP VHOSTS is very useful and shows that Apache is defining the dev server as the default and loading it first . Comment : Very strange . The only other cause I can think of is a typo somewhere but that s quite unlikely . Do you have a proxy or anything else in between that could mess up the Host : header in the request The next step would be to set LogLevel debug in Apache and or do telnet localhost 80 on the server and request for the document directly . Comment : I had a similar issue...the apachectl -t -D DUMP VHOSTS command was the tell all : Mon May 20 23 : 51 : 08 2013 warn default VirtualHost overlap on port 80 the first has precedence .

From the computer which Im trying to surf from I added 192.168.1.2 wordpress.local to its host file . I don t seem to be able to access it though . I tried to ping wordpress.local which gave a message of timeout . How come Comment : If a ping is timing out then either you have network connectivity issues or name resolution issues . Please try to directly ping 192.168.1.2 from the surfing computer . If this does not work verify network connectivity and firewall settings . If this does work verify the IP address shown when you ping wordpress.local is the IP address in the hosts-file . Lastly you may want to try to visit 192.168.1.2 http : 192.168.1.2 from your host computer which shouldn t land at the wordpress site due to vhosts but should land you at some page on that webserver . Comment : From the host computer I can access 192.168.1.2 unsurprisingly . I also can access my surfing computer from my host computer when pinging it this in reverse though throw a timeout message . On my hosting computer my windows-firewall are completely turned off while testing no other firewall is used either . Comment : Have you verified that you are listening on all interfaces by checking the Listen directive in httpd.conf Have you verified the IP address you get when you ping from the surfing computer to wordpress.local is actually the IP of the host computer Comment : I start thinking the problem not has anything to do with WAMP since I can t ping my host computer in any way with WAMP turned off either Hmm.. .

Answer : I ve had similar problems as well with that . I ve been searching around for an answer found some solutions but none of them seemed to work . The only thing that finally made it working not even sure how it actually helped is going into system preferences - sharing and enabling web sharing . That is normally starting your apache2 server but I wasn t using the default one I am running another apache2 process with a different httpd configuration . Anyway after starting it and stopping it from the system preferences window it seemed like it was working . One thing that could be useful is checking your error-log as well as the access log in var log apache2 . Check the access log to see what is the address trying to be resolved . At first whenever I was making a request on my website through the Virtual Host in my access log I only had 127.0.0.1 which is incorrect . After it worked I can see that the requests are www.example.com and not the localhost showing that the virtual host is indeed working .

Answer : In JMeter is it possible to override the hosts-file somehow I mean something that is described here : https : guide.blazemeter.com hc en-us articles 207420205-Hosts-Override .. . .. . What I want to test : Behind a Loadbalancer there are many application servers Apache webservers . The app-servers host different sites via vhosts . They are requested by customers via the loadbalancer . Thehe loadbalancer sends the requests to the app-servers . Based on the url the webserver knows which site is requested . Now I want to send requests directly to the webservers . I could change my hosts-file so a request will bypass the Loadbalancer . but I want to test different webservers at the same time . So I would need a separate Hosts file for every thread group . Comment : why do you want to change it in the middle of the run wouldn t it be simpler to put all servers behind LB in your hosts-file before run and then just target them instead of LB name during run Comment : I have a lot of servers and I want to send requests to all the servers separately . I want to bypass the loadbalancer . But on all servers I need to use the same hostname since they can only be reached via the vhosts configuration . that is why I want a function like the one I linked to in blazemeter because I want to be able to test all server from one loadgenerator JMeter .", "Question : I m writing a script to create virtual-hosts in Mamp Pro . I want them to be created and appear in the GUI next to the normal ones I ve created manually through the GUI . I ve found the following questions on SO : .. . .. . Automatic Virtual Hosts with MAMP Pro http : stackoverflow.com questions 12359199 automatic-virtual-hosts-with-mamp-pro .. . Add MAMP Pro Vhosts with script http : stackoverflow.com questions 32032912 add-mamp-pro-vhosts-with-script .. . .. . Here are my findings so far : .. . .. . I ve found out that the hosts appearing in the MAMP Pro GUI are found in : Library Application Support appsolute MAMP PRO settings3.plist I ve tried editing it but I can t seem to get the entries right with the command PlistBuddy -c print : virtualHosts settings3.plist which says Print : Entry : virtualHosts Does Not Exist .. . .. . From the second question I ve listed above I found out that I can edit the httpd.conf files one found in user library and one in the root library through the GUI . The hosts-file including all of the IP addressing is in private etc hosts .. . .. . The questions are dead even though I commented on the latest one asking for an update on how he solved his scripting problem in the end . In the end I can easily add the values into the hosts-file and the vhosts.conf files to make the website work . My only problem is getting it to show up in the list with the other virtual-hosts in the MAMP Pro GUI . Update : After further investigation and experimentation I realized the process in which the virtual-hosts are created when I first create a host through the GUI the settings3.plist file gets updated when I hit save to save the changes the hosts and httpd.conf files are updated accordingly . I understand that settings3.plist can be converted to an XML through plutil -convert xml1 -o - settings3.plist test.txt and then edit it and convert it back to binary through plutil -convert binary -o - test.txt settings3.plist . My problem with that is that even though I got the gist of how the CP UID works in the XML formats I cannot create a script to undestand the concept check for the position of the values through the list and then put in the values accordingly . I even asked a question about it here : How to add new data values to an NSKeyedArchiver Plist file through a command-line shell script http : stackoverflow.com q 33775025 1934402 Comment : Make sure you work with file Library Application Support appsolute MAMP PRO settings.plist i.e . check that you are working on the right plist file . On my system Mac OS X 10.11.1 El Capitan with MAMP PRO 2.2 the file is settings.plist and the commands from my answer in Automatic Virtual Hosts with MAMP Pro http : stackoverflow.com questions 12359199 automatic-virtual-hosts-with-mamp-pro work fine . What version of MAMP PRO are you on which MAC OS X version In any case the .plist file is an xml file and you could inspect it with an editor and even write a simple script to process it . Comment : I had the chance to look further into this by getting my hands on a MAMP PRO 3.4 used by friend . You are indeed looking at the right file which for version 3.x of MAMP PRO is settings3.plist and it is BINARY FORMAT PROPERTY LIST while for version 2.x of MAMP PRO was settings.plist and was an XML FORMAT PROPERTY LIST . I will try to put my findings in an answer to your question . Comment : I updated my question . @Symvan Also I greatly appreciate your help . Comment : I would avoid the round trip with plutil conversions as it misses the point of automation . My approach is to use PlistBuddy .. . Answer : The solution provided in Automatic Virtual Hosts with MAMP Pro http : stackoverflow.com questions 12359199 automatic-virtual-hosts-with-mamp-pro refers to MAMP PRO version 2.x where host configuration is saved in settings.plist which is an XML format property list file while in MAMP PRO version 3.x host settings are stored in settings3.plist which is a binary format property list file . Even in this format you should be able to do : .. . .. . and still get the contents of the file . Your problem arises from the fact that virtualHosts is no longer there as you will see by running the above command . The above command output is not very helpful for understanding the structure of your plist file so you could run : .. . .. . and then work out the structure of settings3.plist.xml in order to find out which keys to use in PlistBuddy commands . It is a good idea to check the manual pages for plist and PlistBuddy . Do note that key names have changed and the structure is not that clear even in the xml file . I hope this helped . I will investigate further into it and modify this answer if I have a full recipe for editing host details . Comment : I have already found out the structure of the XML file and what the values mean roughly through this post : cclgroupltd.com http : www.cclgroupltd.com geek-post-nskeyedarchiver-files-what-are-they-and-how-can-i-use-them I don t know how to put all of that logic into a shell script .", "Question : I am struggling to configure virtual-hosts on a remote-server to do the following : I have a Tomcat running on port 8888 and want to serve it to the public on port 80 .

Now on another server I have this working with this simple directive .. . .. . But I am limited to what I can do with the vhost on the current server as ISPconfig writes most of it for me and it refuses to write the above config that worked elsewhere . Also I feel editing the file directly will be bad practice I d always be on edge that ISPconfig will rewrite the file for me so I m not really sure how best to proceed with this . My options would be to just go ahead and edit the vhost and hope for the best but if I do that how would I ensure ISPconfig could not overwrite the file without resorting to hacky methods Alternatively is there a config I can enter via ISPconfig that will allow rewrites to happen properly in a way that suits Laravel In this instance any directive entered would need to take precedence over the .php clause as that is written by ISPconfig before any directives entered via the control panel . Comment : I ve created the ispconfig tag this is now the first question under the tag and also removed the nginx tag from this question because as an nginx specialist I can t see how I can be of any help here . .. . Answer : I am not expert with this but from my past experience if I have two domains I would define server blocks for each in two different files and place them in etc nginx sites-available site1.com and etc nginx sites-available site2.com .. . .. . but it looks like you already have a website that you access using mywesite.com which is located at var www mywebsite.com web see the root value of your configuration file .. . .. . Now you install Laravel in test folder in var www mywebsite.com test location . To access this you need can try adding following at the end of your ispconfig file .

The problem I have is that ISPConfig rewrites much of the vhost files for me and I want to avoid having to take control away from ISPConfig Comment : Oh.. .

The issue might be rectified in future release .", "Question : I m working on a WinRT project in which I m playing multiple video files at the same time . I have 3 audio devices attached to machine which will be used distinctively to render audio from video file s that s playing . Maximum number of videos that can be played simultaneously is 3 . Hence each audio device would be used to render audio from its corresponding video file . i.e . Audio device 1 would play video 1 and so on . That s the requirement I have . So far I came across two approaches . First we use Dolby or any other API to channelize audio to corresponding device . i.e . left channel is rendered to device 1 middle center to device 2 and right to device 3 . I ve tried Dolby Audio sample app https : github.com DolbyDev Universal Windows App for Windows 10 . They ve done channeling in embedded video not in code . I couldn t find documentation for Windows 10 Dolby API http : developer.dolby.com tools-tech.aspx . So for this approach can I render audio in form of a channel to a particular audio device And I don t want to merge audio in anyway . Second we use 3 sound cards and attach an audio device to each one . We choose the device we want to play audio on by providing device ID . I ve tried this approach with XAudio2 http : www.newventuresoftware.com blog universal-audio-component-playing-audio-xaudio2 by calling createMasteringVoice method with device ID I want . That worked for single audio file however I want to render audio of multiple videos that are being played . Both approaches didn t solve the core requirement yet . So considering the scenario what is best approach to follow to fulfill the requirement .. . Answer : I would say you can go with XAudio2 as you mentioned in second approach . Since you can pass deviceId to createMasteringVoice you can create multiple instance of UniversalAudioPlayer and pass different IDs to each one . This way multiple sounds can be played concurrently .

Comment : Thanks i tried to use this tag but i dont have enough points : .. . Answer : if you do a adb shell getprop grep dolby you ll see there is a system property dolby.ds.state that toggles between On and Off when it s active playing audio .. . .. . To query the active status from your application this lets you query a System property note that you ll probably have to wrap try-catch blocks round it to keep Java happy .. . .. . It looks like different sorts of audio trigger the Dolby status - if you watch logcat with something like iHeartRadio playing you ll see the the Dolby setting gets bypassed for orbis so you might simply be able to change the codec you are using when you don t want it turned on .

Answer : Explain Python s slice notation .. . .. . In short the colons : in subscript notation subscriptable subscriptarg make slice notation - which has the optional arguments start stop step : .. . .. . Python slicing is a computationally fast way to methodically access parts of your data . In my opinion to be even an intermediate Python programmer it s one aspect of the language that it is necessary to be familiar with . Important Definitions .. . .. . To begin with let s define a few terms : .. . .. . start : the beginning index of the slice it will include the element at this index unless it is the same as stop defaults to 0 i.e . the first index . If it s negative it means to start n items from the end . .. . stop : the ending index of the slice it does not include the element at this index defaults to length of the sequence being sliced that is up to and including the end . .. . step : the amount by which the index increases defaults to 1 . If it s negative you re slicing over the iterable in reverse . How Indexing Works .. . .. . You can make any of these positive or negative numbers . The meaning of the positive numbers is straightforward but for negative numbers just like indexes in Python you count backwards from the end for the start and stop and for the step you simply decrement your index . This example is from the documentation s tutorial https : docs.python.org 2 tutorial introduction.html but I ve modified it slightly to indicate which item in a sequence each index references : .. . .. . How Slicing Works .. . .. . To use slice notation with a sequence that supports it you must include at least one colon in the square brackets that follow the sequence which actually implement the getitem method of the sequence according to the Python data model https : docs.python.org 2 reference datamodel.html object . getitem . Slice notation works like this : .. . .. . And recall that there are defaults for start stop and step so to access the defaults simply leave out the argument n in the notation . Slice notation to get the every other elements from nine elements from a list or any other sequence that supports it like a string would look like this : .. . .. . When I see this I read the part in the brackets as 9th from the end to the end . Actually I abbreviate it mentally as -9 on .. . .. . Explanation : .. . .. .

Give your slices a descriptive name You may find it useful to separate forming the slice from passing it to the list . getitem method that s what the square brackets do https : docs.python.org 2 reference datamodel.html object . getitem . Even if you re not new to it it keeps your code more readable so that others that may have to read your code can more readily understand what you re doing . However you can t just assign some integers separated by colons to a variable . You need to use the slice object : .. . .. . The second argument None is required so that the first argument is interpreted as the start argument otherwise it would be the stop argument https : docs.python.org 2 library functions.html slice . You can then pass the slice object to your sequence : .. . .. . Memory Considerations : .. . .. . Since slices of Python lists create new objects in memory another important function to be aware of is itertools.islice . Typically you ll want to iterate over a slice not just have it created statically in memory . islice is perfect for this . A caveat it doesn t support negative arguments to start stop or step so if that s an issue you may need to calculate indices or reverse the iterable in advance . The fact that list slices make a copy is a feature of lists themselves . If you re slicing advanced objects like a Pandas DataFrame it may return a view on the original and not a copy .

Answer : Square brackets following a sequence denote either indexing or slicing depending on what s inside the brackets : .. . .. . Both of these cases are handled by the getitem method of the sequence or setitem if on the left of an equals sign . The index or slice is passed to the methods as a single argument and the way Python does this is by converting the slice notation 1 : 10 : 2 in this case to a slice object : slice 1 10 2 . So if you are defining your own sequence-like class or overriding the getitem or setitem or delitem methods of another class you need to test the index argument to determine if it is an int or a slice and process accordingly : .. . .. .

Answer : I find it easier to remember how it s works then I can figure out any specific start stop step combination . It s instructive to understand range first : .. . .. . Begin from start increment by step do not reach stop . Very simple . The thing to remember about negative step is that stop is always the excluded end whether it s higher or lower . If you want same slice in opposite order it s much cleaner to do the reversal separately : e.g . abcde 1 : -2 : : -1 slices off one char from left two from right then reverses . See also reversed http : www.python.org dev peps pep-0322 . Sequence slicing is same except it first normalizes negative indexes and can never go outside the sequence : .. . .. . Don t worry about the is None details - just remember that omitting start and or stop always does the right thing to give you the whole sequence . Normalizing negative indexes first allows start and or stop to be counted from the end independently : abcde 1 : -2 abcde 1 : 3 bc despite range 1 -2 . The normalization is sometimes thought of as modulo the length but note it adds the length just once : e.g . abcde -53 : 42 is just the whole string .

Answer : Note that in go 1.2 Q4 2013 1.2rc1 is available now http : code.google.com p go downloads list you can associate to a slice a capacity of its own instead of a capacity deduced from the underlying array . See Three-index slices http : tip.golang.org doc go1.2 three index and the design document http : golang.org s go12slice . A slicing operation creates a new slice by describing a contiguous section of an already-created array or slice : .. . .. . The capacity of the slice is the maximum number of elements that the slice may hold even after reslicing it reflects the size of the underlying array .

Answer : This is how I teach slices to newbies : .. . .. . Understanding difference between indexing and slicing : .. . .. . Wiki Python has this amazing picture which clearly distinguishes indexing and slicing . enter image description here http : i.stack.imgur.com o99aU.png .. . .. . It is a list with 6 elements in it . To understand slicing better consider that list as a set of six boxes placed together . Each box has an alphabet in it . Indexing is like dealing with the contents of box . You can check contents of any box . But You can t check contents of multiple boxes at once . You can even replace contents of the box . But You can t place 2 balls in 1 box or replace 2 balls at a time . Slicing is like dealing with boxes itself . You can pickup first box and place it on another table . To pickup the box all You need to know is the position of beginning ending of the box . You can even pickup first 3 boxes or last 2 boxes or all boxes between 1 4 . So You can pick any set of boxes if You know beginning ending . This positions are called start stop positions . The interesting thing is that You can replace multiple boxes at once . Also You can place multiple boxes where ever You like . Slicing With Step : .. . .. . Till now You have picked boxes continuously . But some times You need to pickup discretely . For example You can pickup every second box . You can even pickup every third box from the end . This value is called step size . This represents the gap between Your successive pickups . The step size should be positive if You are picking boxes from the beginning to end and vice versa . How Python Figures Out Missing Parameters : .. . .. . When slicing if You leave out any parameter Python tries to figure it out automatically . If You check source code of CPython You will find a function called PySlice GetIndicesEx which figures out indices to a slice for any given parameters . Here is the logical equivalent code in Python . This function takes a Python object optional-parameters for slicing and returns start stop step slice length for the requested slice . This is the intelligence that is present behind slices . Since Python has inbuilt function called slice You can pass some parameters check how smartly it calculates missing parameters .

The key point to remember is that the : end value represents the first value that is not in the selected slice .

Answer : I have a Spring Integration application where I have a JMS inbound channel adapter that will receive messages from a queue in a remote JMS broker . I m looking up the connection factory directly from the broker s remote JNDI service and this is what I use to set up my inbound channel adapter . I understand that behind the scenes there is a DefaultMessageListenerContainer . According to AbstractMessageListenerContainer javadocs found here http : docs.spring.io spring-framework docs 2.0.x api org springframework jms listener AbstractMessageListenerContainer.html if sessionTransacted is set to true for the DMLC local JMS transactions will be used for the delivery of messages from the broker . I m not interested in having the receipt of messages to be part of externally managed transactions . Now if the JMS broker provides a resource adapter and therefore there is a JCA managed connection factory that might be capable of participating in JTA transactions configured in a JBoss App server where my Spring Integration is running packaged in a war . I could use this instead of directly looking up from the broker s JNDI as I described above . Since I am not interested in global transactions I don t see the value of using this JCA connection factory moreover I don t know if the caching of connections sessions that JCA does might clash with the DMLC caching strategy . Additionally I m not sure if adding a JCA layer to wrap the original connection factory will impact performance . Which is the right approach then take connection factory directly from broker JNDI and let DMLC handle everything or take a JCA managed connection There seems to be a not very well documented school of thought that tells that JCA is safer and more robust but if I m not using EJBs I dont see how this can be true .", "Question : The java doc here http : docs.spring.io spring docs 3.2.4.RELEASE javadoc-api related to Spring CachingConnectionFactory has comment : .. . .. .

With the request response being asynchronous when I inject a message via the initial Gateway the message goes all the way to JMS OUT QUEUE . Beyond this message flow a reply message is put back into JMS IN QUEUE which it is then picked up by JmsGatewayIn . At this point the message is Processed and placed into out.ch I know the response gets to out.ch because I have a logger interceptor there which logs the message being placed there but the Gateway never receives the response . Instead of a response the system outside of this message flow which picked up the message from JMS OUT QUEUE and placed the response in JMS IN QUEUE receives a javax.jms.MessageFormatException : MQJMS1061 : Unable to deserialize object on its own JmsOutboundgateway I think it is failing to deserialize a jms reply object from looking at the logs .

My Gateway is configured as follows : .. . .. . My Integration flow is configured as follows : .. . .. . Thanks for any help on this PM . .. . Answer : First of all your configuration is bad : .. . .. . 1 . Since you start the flow from WsGateway process you really should wait reply there . The gateway s request reply capability is based on TemporaryReplyChannel which is placed to the headers as non-serializable value . 2 . As long as you wait rely on that gateway actually there is no reason to provide the replyChannel if you aren t going to do some publish-subscribe logic on the reply . 3 . As you send message to the JMS queue you should understand that consumer part might be a separete remote application . And the last one might know nothing about your out.ch . 4 . The JMS request reply capability is really based on JMSCorrelationID but it isn t enough . The one more thing here is a ReplyTo JMS header . Hence if you are going to send reply from the consumer you should really just rely on the JmsGatewayIn stuff . So I d change your code to this : .. . .. .

I had first tried replacing the Jms In Out Gateways with Jms In Out Adapters but had trouble configuring those too . Then I tried only Jms Out Gateway with replyDestination as in your solution and that worked okay . I hadn t removed the initial @Gateway s replyChannel which as you mentioned is not needed . Thanks Comment : Hello again I find myself needing to come back to this post.. . I have a requirement where I believe I do need to use separate JMS Inbound Outbound adapters to allow for asynchronous responses . In order to do this I have again set a replyChannel out.ch on WsGateway switched the Jms.outboundGateway to both a Jms.outboundAdapter and Jms.inboundAdapter and have set JMSCorrelationID header on the message before sending out but when response comes back and placed into out.ch the WsGateway does not pick up the response message My SI flow is actually a bit more complicated than shown here.. .

Answer : To my knowledge there is no Spring specific way of sending an unsubscribe command to the MQ server however you always have the option of obtaining an underlying JMS Session by extending the DefaultMessageListenerContainer http : static.springsource.org spring docs 3.0.x javadoc-api org springframework jms listener DefaultMessageListenerContainer.html class and calling getSession http : static.springsource.org spring docs 3.0.x javadoc-api org springframework jms listener AbstractPollingMessageListenerContainer.html getSession 28org.springframework.jms.connection.JmsResourceHolder 29 or createSession http : static.springsource.org spring docs 3.0.x javadoc-api org springframework jms support JmsAccessor.html createSession 28javax.jms.Connection 29 .

So whilst I have no reason to doubt the advise below I am not able to test it as I can t figure out how to get AQ JMS to not attempt a commit . Will update as I learn more . .. . Answer : My understanding is that JMS producers are inherently transacted via JTA . By sending a message via JMS MessageProducer the thread-local JTA transaction is used if one is present . This is hinting at by the Spring manual section 21.2.5 http : static.springsource.org spring docs 3.0.x reference jms.html jms-tx : .. . .. . JmsTemplate can also be used with the JtaTransactionManager and an XA-capable JMS ConnectionFactory for performing distributed transactions . Note that this requires the use of a JTA transaction manager as well as a properly XA-configured ConnectionFactory . This is also suggested by JmsAccessor.setSessionTransacted the superclass of JmsTemplate javadoc http : static.springsource.org spring docs 3.0.x javadoc-api org springframework jms support JmsAccessor.html setSessionTransacted 28boolean 29 : .. . .. . Set the transaction mode that is used when creating a JMS Session . Default is false . Note that within a JTA transaction the parameters passed to create Queue Topic Session boolean transacted int acknowledgeMode method are not taken into account . Depending on the J2EE transaction context the container makes its own decisions on these values . Analogously these parameters are not taken into account within a locally managed transaction either since the accessor operates on an existing JMS Session in this case . .. . Setting this flag to true will use a short local JMS transaction when running outside of a managed transaction and a synchronized local JMS transaction in case of a managed transaction other than an XA transaction being present . The latter has the effect of a local JMS transaction being managed alongside the main transaction which might be a native JDBC transaction with the JMS transaction committing right after the main transaction . So by start a JTA transaction i.e . by using Spring s transaction API with JtaTransactionManager and calling JmsTemplate.send .. . you will be sending the message bound to that transaction .

I updated the code here . jsfiddle.net Kpmcn 2 http : jsfiddle.net Kpmcn 2", "Question : I m using the Flotr2 lib : https : github.com HumbleSoftware Flotr2 .. . .. . I have been searching everywhere to just understand how to add a callback or an event handler which gets triggered when the Flotr graph is actually finished with its drawing . My graph draws okay with small or mid size data but when I use a larger set of data the graph takes much longer to draw . While it s trying to draw the graph container is blank so I would like to show a loading spinner while it s trying to draw and hide this spinner when the graph is actually finished with its drawing . So my question is how to know when the graph has really completed its drawing Could someone please point me to the right direction or provide with some code sample . Any help would be much much appreciated . Thank you Comment : I ve only tried my answer with smallish data sets that I have handy . You might want to show your code so people know what you re working with . .. . Answer : You can wrap the call to Flotr.draw in another function and just put your spinner code inside the calling function . I ve used windows.onload as a wrapper but you could also use a custom function that you call explicitly . Comment : Thanks . It worked .", "Question : I need help to display chart in tapestry pages .

Answer : I think you can do most of what Qi4j does and way way more with AspectJ ITDs the language not the @AspectJ Java alternative . Jordao mentions it in his answer to the similar post http : stackoverflow.com a 2893712 318174 mentiond by @Ischin http : stackoverflow.com questions 6068772 qi4j-alternatives comment7027745 6068772 . Here is an example of trait-like functionality I mentioned in another post : http : stackoverflow.com a 7403617 318174 . Just by adding an interface to a class you can magically add methods . Comment : Sure but keep in mind that AspectJ force you to use their toolchain and that you can t use it with plain JDK . It means that you ll need to tweak your build and use a AspectJ enabled IDE . Once compiled of course AspectJ based code works on any JRE . Qi4j do not have this downside . Comment : Qi4J in my mind has way more downsides in that your tightly coupled to a library . Such is not the case with AspectJ and will work great with any framework like Spring or JPA . Also with AspectJ you can now refactor with either eclipse or I think Maven to do the code weave inline . That is you can actually tell AspectJ to modify your code . ie you can remove the AspectJ dependency if you want to in the future . AspectJ is also agnostic of your architecture methodology whether its plain OOP or Component oriented Functiona separation of behavior and state . Qi4j is not . Comment : You can write Qi4j agnostic code and use Qi4j assembly code to compose it . Moreover Qi4j provides more than just composites and AOP constructs : a DDD oriented framework libraries extensions and dev tools . Composite Oriented Programming is at Qi4j s heart but its scope goes beyond that . Comment : Nothing stops you to use only qi4j-core alongside anything you re already using or choose to use more from the SDK . Obviously the more you use the more your software depend on Qi4j to run but it s about the same with all frameworks libraries or tools . BTW AspectJ is awesome and has greatly inspired Qi4j .

I would like to know what does Qi4j provide to support SQL databases Thanks .. . Answer : Qi4j SQL support is like everything Qi4j an opt-in collection of libraries and extensions . First you can use Qi4j in applications that already use something else to handle persistence JDBC JPA or any other technology . The Qi4j core is small and you are free to use or not librairies and extensions present in the SDK . If you don t want to use Qi4j persistence support ie . Entities and Query API you still can leverage the SQL Library that allows you to manage DataSources connection pools as Qi4j Services . As stated in the documentation the SQL Library give you CircuitBreaker Library and Qi4j I O API integration for free . Moreover you can choose to either import an existing DataSource useful if you deploy your application in a container and you want that container to manage the DataSource or use any of the following connection pools implementations : Apache DBCP C3P0 or BoneCP . See http : qi4j.org latest library-sql.html .. . .. . Qi4j persistence relies on Entities stored in an EntityStore . The SDK provides many EntityStore implementations including one based on SQL databases . There s support for the following databases : PostgreSQL MySQL MariaDB SQLite embedded H2 embedded or server and Apache Derby aka . Oracle JavaDB both in embedded and server modes . See http : qi4j.org latest extension-es-sql.html .. . .. . Qi4j Query API relies on Index Query services . Again the SDK provides several implementations including one based on SQL databases . At the time of writing it supports only PostgreSQL as a backend but work is being done to support as many SQL databases as the SQL EntityStore . See http : qi4j.org latest extension-indexing-sql.html .. . .. . Finally an application sample demonstrates how to use all the SQL support provided by the Qi4j SDK for you to get started from .

Answer : Well I ve been using Qi4j myself for about a year now in a project . Once you get used to the power of mixins in your domain-model you ll be wondering how you ever managed without them before . In fact I think the POJO method of creating domain models should be obsolete . It creates systemically unmaintainable code . Because the mixin composite model is the important feature of Qi4j rather than DI there really isn t any comparison on the Java platform . As for Bozho s concerns : when it comes to declaring mixins there are two separate cases . In entities i.e . the domain-model an interface will typically only have one implementation and you would in fact want to actively avoid having several implementations for maintenance and readibility reasons . So I declare the implementation straight in the interface . But it is only a default which can be overriden by the composite if you want to . I ve so far never found a need to do so . The other case is services which is quite different . For many cases there will be only one implementation and so declaring the implementation in the interface is again quite ok . But there are far more cases with services that you want different implementations and so for those cases you simply declare the mixin in the concrete composite type declaration instead . So both styles are possible and recommended for various reasons . As for casting being able to cast an object is a bonus not a problem . If you don t have casting from one role to other roles you re going to have to be quite inventive to get around it which probably won t make your code simpler .", "Question : In Qi4j you have to assemble the composites . Can someone tell me where to handle this in a JSF 2.0 application Should i extend the FrontController-Servlet Or is it enough to assemble at the point when the application is being deployed and started Thanks a lot .. . Answer : Using a Qi4j application in a servlet context is quite easy . Qi4j provide a small library supporting this use-case : qi4j-lib-servlet . All you need is to extends AbstractQi4jServletBootstrap http : qi4j.org latest javadocs org qi4j library servlet lifecycle AbstractQi4jServletBootstrap.html which is a ServletContextListener and register it in your webapp . The only abstract method of this class is from the ApplicationAssembler interface . Your Qi4j Application will then be assembled and bootstrapped alongside your webapp and the Qi4jServletSupport class provided by the very same project will allow you to get a handle to your Qi4j Application from your code for example in your managed beans .", "Question : I was reading an InfoQ article on Composite Oriented Programming earlier on : .. . .. . http : www.infoq.com articles Composite-Programming-Qi4j .. . .. .

Answer : Hopefully not too late on this discussion : But this is how I see it . First of all I like the ideas Composites Mixins Assemblies behind Qi4j but am held back by the complexity of using it . The concepts there should be part of wider umbrella such as a language such as Java than a framework and should be easier to use . I ran into a problem 2 years ago that left me wishing I had something like that then . I wanted 3 different behaviors that could be reused on a set of beans . Some beans used all of them others any combination of two . I did not want to put all of them together in a class because it did not make sense . On the other hand I was constrained by the fact that I could not have multiple-inheritance . The obvious solution : use an interface which means implement the thing that many times . I remember complaining to a co-worker about the fact that I hope I had a way of providing a default implementation for an interface . This to me is a simple OO concept that allows one to reuse behaviors in a cleaner fashion . And if it is the case where you need something different than the default implementation than implement that one . That would make more sense and would not brake any natural law that I can see . So to answer your question I think this Qi4j s concepts allow you to think OO in cleaner fashion where Spring is more structural and not even comparable conceptually . You could be thinking dependency-injection and not be thinking spring and be thinking Qi4j and not be thinking dept injection .", "Question : I m currently trying to figure out how Qi4j works .

Answer : Qi4j consists of many many artifacts to keep the total footprint down as most applications won t use all bits and pieces . contains the artifacts as of 1.3 .. . .. . For compile scope api and bootstrap should be enough . testsupport is obviously test scope and runtime should not be used by your code and only be a runtime dependency . The Libraries varies greatly in completeness and quality . Extensions can depend on libraries but not the other way around . Extensions implements the slowly growing SPI pluggable functionalities entity stores indexing query and caching . Next release 2.0 will have more extensions for value serialization and others .

Answer : Kabram Integration with JPA has been attempted more than once . If we have two overlapping but not fully compaible technologies you will end up only with the intersection of possibilities . So there are two basic approaches to integrate Qi4j with JPA . 1 . To limit the JPA options so that the much more flexible data-structures that Qi4j needs can fully be used . Doing that makes no sense as going directly to SQL is much more performant and that is what we chose . 2 . To limit Qi4j s data model to fit an existing JPA data model . Doing this will take away most of the advantages of why people choose Qi4j in the first place . We have therefor decided not to spend the cycles to do this . However I think the extensibility of Qi4j is good enough to do such integration without hacking in the Core Runtime and simply create an EntityStore .", "Question : I m currently trying to figure out how Qi4j works .

Answer : Bozho For you question about Mixins being declared on interfaces .. . .. . The Mixin implementations can be overridden either in higher i.e . sub- interfaces as the seek order for implementations happen per method and goes from the declared interface left-to-right and then to each of the super interfaces also left-to-right in the extends clause . OR you can override in the Assembly of a composite .. . .. . where the LdapAuthenticatorMixin may be abstract and only override a single method .", "Question : I just found an article http : www.infoq.com news 2008 11 Qi4j on a framework in Java that apparently allows it to support Mixins http : en.wikipedia.org wiki Mixin and something called Composite Oriented Programming which for all I know might even be the same thing.. . I ve also heard of worked with AOP and I m not sure how it differs from this either.. . .. . Answer : Mixin is never meant as stand alone class .

I ve also heard of worked with AOP and I m not sure how it differs from this either.. . .. . Answer : At a language-agnostic level a mixin just adds functionality to a class and is more for programmer convenience and to avoid code duplication . An abstract base-class forms an is-a relationship and allows for polymorphism . One reason why inheritance is overused is that it s an easy way to implement mixins without writing any boilerplate in languages that don t really support them . The problem is that you re declaring a polymorphic is-a relationship as a side effect making your API more confusing and possibly adding ambiguity . Hence newer languages like D and Ruby support mixins as native features allowing a convenient way to add a bunch of functionality to a class without declaring a polymorphic is-a relationship .

Comment : @Bruno A core language like C++ Comment : concise and very clear . Awesome explanation Comment : I think the point about making an incorrect unnecessary is-a relationship is a good point .

Comment : Little update : now in 2014 it seems that Unitils is almost abandoned while spring-test is under active development . So answer which one to choose seems clear . .. . Answer : We use Unitils and Spring s test framework on our project . With unitils one thing we ran into problems with was having more than one PersistenceUnit . Unitils does not support it . Of course spring does . Another problem we ran into I posted about here : Using unitils dbMaintain to maintain database how to exclude scripts from being run http : stackoverflow.com questions 6143505 using-unitils-dbmaintain-to-maintain-database-how-to-exclude-scripts-from-being .. . .. . Basically unitils does not have all the latest features of each of the underlying frameworks such as DBMaintain because unitils uses old versions of the other frameworks under the covers . That said Unitils does have some great convenience-methods like some of the ones provided in DatabaseUnitils http : www.unitils.org apidocs org unitils database DatabaseUnitils.html . We particularly like updateSequences .. . .. . So for ultimate flexibility and or if you anticipate a fairly complex code-structure I would stick with Spring s test framework whenever possible . In many other cases unitils is a very handy tool . And a little p.s.. . when possible I would recommend favoring unit tests and mocking frameworks like Mockito versus integration tests . I ve always been an integration test heavy tester and on this last project it has turned into a bit of a maintenance challenge . Comment : thanks for sharing your experience : You re mentioning using Mockito - do you prefer it over EasyMock which is already bundled with Unititls Comment : I ve heard good arguments for against both frameworks . I haven t used EasyMock . When I was reading about it vs mockito and their associated documentation mockito just seemed simpler and more straightforward . So I chose mockito . YMMV . Comment : The EasyMock support in Unitils is deprecated now . Instead it offers the Unitils Mock module which provides a modern mocking API that is IMO significantly better than the EasyMock or Mockito APIs .", "Question : I am trying to get scala specs and unitils-dbunit to work . To use unitils you have to annotate your test class with @RunWith classOf UnitilsJUnit4TestClassRunner or extend from a class and you can set DataSet s to load with @DataSet Array DataSet.xml . All of this works with JUnit . But I got 2 problems when using specs : .. . .. . I am running my specs tests with gradle and the ScalaTestAntTask so I guess the @RunWith annotation will be ignored .

Does somebody know how I can use specs and unitils together UPDATE : This is the solution I came up with : .. . .. . -- Christian .. . Answer : The DataSet annotation can t be applied directly to xxx should because this is not a test method just a regular scala code call . I can t give you a fully working solution but what you need to do is to dig out the unitils API and use the DataSetFactory http : www.unitils.org apidocs org unitils dbunit datasetfactory impl MultiSchemaXmlDataSetFactory.html directly to load your data . I think that you can more or less reuse the code found here http : www.java2s.com Open-Source Java-Document Testing unitils org unitils dbunit DbUnitModule.java.htm . Then if you need to load this dataset before each example just use a doBefore http : code.google.com p specs wiki DeclareSpecifications Call a function before or after each example call .

And i changed it to : database.url jdbc : mysql : localhost : 3306 test .. . Answer : I would say that the problem is here : .. . .. . Try setting it to the following instead : .. . .. . Ultimately the class MySqlDbSupport has a bug in it . If the database.identifierQuoteString.mysql property is set to none in the properties file a private field named identifierQuoteString in the class DbSupport is set to null . The toCorrectCaseIdentifier method in MySqlDbSupport fetches the value of this field but forgets to do a null-check before passing it to String.startsWith . Hence we get a NullPointerException . Using auto asks the database for the identifier-quote string to use . I don t see why you would want to use anything other than this . Comment : Hi Luke You are the only one person who trying to help . Thanks . I had used your advice in my unitils-local.properties . I had updated my question if you had some time just look at the updated last part of question . Maybe you know something about this problem . Comment : @davakin111 : to be honest I don t know anything much about Unitils I ve never used it myself other than it appears to have been more-or-less abandoned in 2011 . I based my answer on reading the source code of Unitils . The exception you mention in your most recent edit comes from within DbUnit which I haven t used either . Sorry I don t think I can help you any more here . Comment : Thank you for your reply.That s ok : Did you know some frameworks for database testing something very similar to Unitils Comment : @davakin111 : sorry no I don t . Comment : @davakin111 some time passed but this answer http : stackoverflow.com a 34659291 1037316 might be what you asked for .", "Question : I guess I need someone with extensive knowledge to solve my current problem : .. . .. . I use Eclipse to debug jUnit-tests that use Unitils . While debugging some or all of the tables in my database are locked even though they are not accessed at the moment . The result is that other developers working on the same database are unable to run tests as long as I m debugging or vice versa . Logically I don t see a reason why the tables should be locked the whole time . So should I try to deactivate locking Do you know how to configure that Though I can think of alternative approaches I d really like to have these questions answered for this would be the most convenient solution . EDIT : The tests run on an Oracle DB with empty tables . Before each test Unitils empties EVERY table unusual configuration for Unitils and then inserts specific test data . All constraints are active which again is an unusual configuration . When I m debugging and another developer starts a jUnit-Test their IDE freezes until they get a DB timeout or I stop debugging due to Unitils trying to empty the tables again . Comment : Which DBMS are you using Oracle PostgreSQL Comment : Oracle via JPA . Shouldn t matter though . Comment : It matters a lot actually because some DBMS impose more locking than others . e.g . in MySQL MyISAM an update of a single row will lock the whole table in SQL Server a read-only SELECT will block all retrieved rows from being updated from other sessions and so on . Do you actually see table locks when you e.g . query V LOCK What does the application or the test environment do when you start it It s nearly impossible to answer your question without more details what your tests are doing during startup . Comment : I would strongly urge you not to run unit tests against a live database . It s much better faster easier to run tests against a mocked database . Comment : Ok will query the data-dictionary next time to find out . See EDIT for more details . .. . Answer : Solution : Stopped using Unitils . DBUnit alone is enough and this problem is gone . Though this decision was made because Unitils is no longer supported .", "Question : I m new to unitils built-in dbunit and spring . At the new place I m working I can see that some of the testing is with spring and others using unitils dbunit without spring . There is a push to use spring so I ve been trying to merge the following functionality . Spring tests using : .. . .. . This class has the @Autowired ProfileDao which works when using the @RunWith SpringJUnit4ClassRunner.class . Unitils tests using : .. . .. . Which correctly loads the database etc when run . What I m trying to achieve is to combine these so that I can Unitil ise my class with the @RunWith UnitilsJUnit4TestClassRunner.class annotation but also make use of spring in the normal way as in the previous class . Problem is I can t seem to unitilise my class whilst using the spring version as they re both JUnit4ClassRunner extensions . I ve tried a variety of variations but have not been able to get any to work . Can anyone advise on a decent way of doing this Thanks .. . Answer : Unitils has a Spring integration package : .. . .. . We ve not had to migrate from Spring tests but do use Spring and Unitils together . Rather than using the @RunWith annotation we subclass : .. . .. . We recently ran into a problem where our test data wasn t being loaded properly the first time . This could be a conflict between the Unitils and Spring transaction handling . I m not really sure but turning off transactions in Unitils by setting this property : .. . .. . in the unitils.properties file got around the problem .", "Question : anybody knows whether unitils project http : unitils.org is still alive . On there pages last version is 3.3 in maven repository it is 3.4.2 . Actually there is google cached version of their pages where the version is said to be 3.4.2 .. . .. . Anyway is there any replacement for this project . I kind of lack the vivid community around and really don t want to be bound to dying project . .. . Answer : Unitils seems to be almost abandoned nowadays . Project is available on the GitHub here https : github.com arteam unitils and you can look at its history and activity . Anyways my two cents.. . .. . .. . Unitils has serious drawbacks : .. . .. . Integrates many third-party libs easymock dbunit spring dbmaintainer xmlunit slf4j etc and thus forces their versions - it is a really serious drawback .. . Due to being dependent on many 3rd party libraries it is almost impossible to keep it up to-date without any company behind . Unitils 4.0 is developed since 06.2011 and was planned to release at 01.2012 but now 01.2016 after 4 years is still not released . DbUnit .. . .. . For database-driven apps it may seem that interesting way to go is a plain DbUnit + Spring-Test or alternatively some 3rd party tools : .. . .. . excilys spring-dbunit https : github.com excilys spring-dbunit that comes with handy @DataSet annotation and is actively developed on the github also is constantly updated to use the newest versions of DbUnit and Spring Framework . springtestdbunit spring-test-dbunit https : github.com springtestdbunit spring-test-dbunit which is also hosted on the github comes with a @DatabaseSetup annotation . Both are very similar but personally I find DbUnit confusing quite cumbersome and time-consuming . Why Try to maintain large amount of small xml files and you find out what I mean . Also combining multiple data sets is really hard . DbSetup .. . .. . My choice . DbSetup http : dbsetup.ninja-squad.com doesn t need external xml json files is extremely convenient and allows you to combine freely multiple data sets using fluent builders . Just look at code below : .. . .. . Everything is java so you can freely refactor it extract methods etc . Hope it helps . Comment : The version madness is complete not only inside libraries but unitils itself . The usage of mockito vs . easymock is terrible . But so far I have been kind of happy but now I have waken up to realize that I have slept to long . DBSetup looks good but for bigger table the setup can clutter the code heavily . Although I really agree about maintaining multiple .xmls been big burden . Comment : Another thing is that the projects you offered are Spring bounded . We are unfortunately not using Spring at all . Comment : @Zveratko yes and no.. . DbSetup is not bounded to Spring at all - it just needs a DataSource to operate on . All other mentioned by me possibilities : yes they need Spring - but surprisingly it s not a blocker too because you can use spring-test module within unit tests without using Spring at all in your normal classes .

Does this happen in org.unitils.UnitilsJUnit4 library I would like to make my own implementation for anotation no code ready yet . .. . Answer : Depends on which part of the processing that you are looking for . If you mean where the actual DataSet is processed then check out the DbUnitModule class . From the API http : www.unitils.org apidocs org unitils dbunit DbUnitModule.html : .. . .. . Loading of DbUnit data sets can be done by annotating a class or method with the DataSet annotation . The name of the data set files can be specified explicitly as an argument of the annotation . If no file name is specified it looks for a file in the same directory as the test class named : classname without packagename .xml . If you are referring to the code that actually looks for things that are annotated with @DataSet then they have a helper class called AnnotationUtils API http : www.unitils.org apidocs org unitils util AnnotationUtils.html which has a bunch of methods for accessing annotated items . This is used by the DbUnitModule mentioned above to find whatever data set is needed for a given test .", "Question : Any ideas how this can be done with Unitils dbunit Date relative to current in the DBUnit dataset http : stackoverflow.com questions 2856840 date-relative-to-current-in-the-dbunit-dataset .. . .. .

I have tried some code copied from the link provided but getting errors about using -placeholder in my xml . .. . Answer : A simple solution might be to just use placeholders in your xml dataset eg . xml version 1.0 encoding UTF-8 dataset user userName jdoe name doe firstname john lastLogin YESTERDAY user userName jdoe name doe firstname jane lastLogin A WEEK AGO dataset .. . .. . and do some post-processing replace the placeholders with the calculated values before you run your tests .

Answer : Coincidentally I was trying to pick up unitils for my db testing as well . I was able to replicate your problem with maven 2.2.1 .

If there is any problem it probably lies with the pom definitions related to hibernate and sure enough in the pom for unitils-orm the following dependencies are set as optional : .. . .. .

That in turn needs UnitilsJUnit4TestClassRunner.class which extends JUnit4ClassRunner . AFAIK UnitilsJUnit4TestClassRunner does not have any implementation on how Unitils processes the annotation @InjectInto . The basic idea behind this question - This annotation does not support injection of Mockito mocks . I just want to check if it is possible to to add some implementation that can do this . If there is any other direct solution that integrates Mockito with Unitils even that is welcome . .. . Answer : Yeah Unitils doesn t support Mockito . However Mockito comes with handy mock injection utility annotations . You could write in your JUnit test something like that : .. . .. . Note that it only works with mockito mocks or spies . Comment : thanks for your reply . That is a nice piece of information but @ InjectMock works only when we have a setter or constructor based injection in the CUT.. . but in my case I am using EJB3.x which does not need these . So it may be an additional overhead in my case to write a setter method in the CUT for mock injection . Comment : Actually Mockito 1.8.5 does field injection . Version 1.9 adds it all with setter injection then field injection if setter injection is not possible . Comment : thanks it works : -", "Question : It seems to be a simple question . I have some unitils tests in a spring application . The database contains some oracle views and i just want to insert dataset into these views . I know that it is possible to set options to DBunit Table Type properties . But i find nothing for unitils . Is there some unitils properties for inserting dataset to views Thank you for help Comment : Inserts can only be performed on simple views views that are based only on one table . You cannot insert records into views that are the results of joins on multiple tables . The first thing you need to do is determine whether or not you can insert into the view . Comment : Probably you want to add data to the tables that actually are used for having the views.. .

However recently I have found the existence of a library called JBox2D https : github.com jbox2d jbox2d . Is there any difference between this two libraries What the advantages of one from another I know they both are based on the Box2D https : github.com erincatto Box2D library for c++ because of this : .. . .. . The Box2D implementation in libgdx is a thin Java wrapper around the C++ engine . .. . .. . JBox2d is a Java port of the C++ physics engines LiquidFun and Box2d . But what do they mean by port and wrapping Is JBox2D more complete than Box2D which one is faster I ask this because I want to know if change my project from one to another in this case from Box2D to JBox2D can affect or optimize the performance of my game . Comment : Wrapping would mean that their is a thin essentially non-functional API which makes it easier to call the underlying API from Java . It basically acts as a proxy between Java and presumably the native implementation . A Port is where the actual code has been translated from C++ to Java so the ported version becomes presumably pure Java and doesn t rely on any external native libraries Comment : Do this make the port one slowly Comment : You d have to bench mark some times yes some times no . The port would be easier to get running on multiple platforms as you won t need to worry about ensuring that the correct libraries are installed for example also it won t suffer from issues such as updated libraries on the platform OS which might cause issues .. . Answer : As MadProgrammer said the libgdx box2d extension gdx-box2d is a JNI wrapper around the native box2d library . While the JBox2D library is completely written port in Java and doesn t rely on the native library . However you might find it interesting to know that the gdx-box2d extension uses JBox2d https : github.com libgdx libgdx tree master extensions gdx-box2d gdx-box2d-gwt src com badlogic gdx physics box2d gwt emu org jbox2d behind the scenes when it is not possible to wrap the native library . Which is only the case for the GWT backend . In most cases specifically Android it is faster to use the JNI wrapper instead of JBox2d it is probably also faster on iOS because RoboVM needs to translate the JBox2D bytecode . Which is why the extension uses that on the those backends . Of course this depends on that actual scenario so you should benchmark and compare it know the actual difference . I haven t bench marked gdx-box2d vs JBox2d myself . But I can say from experience that the 3D physics gdx-bullet JNI wrapper is much faster compared to the JBullet Java port . Please note that the gdx-box2d includes the required libraries . It does not depend on any libraries on the platform that needs to be updated . You also don t need to worry about ensuring that the correct libraries are installed . Comment : I ll have to learn how to benchmark then it s a new word for me do just porting my game from one library to another and then measure time performance for both count as bench marking or there are standard on how to benchmark Comment : Unless there s an actual performance problem you re trying to solve and you actually found that box2d is causing that problem and you verified that it is not a problem with your own code e.g . misusing the API you shouldn t even think about this . First identify the problem then try to solve .

Answer : Anything you can do in Java you can do in Processing . But the code you posted is not Java . It s C++ . Edit : George pointed out that it looks like ActionScript . Either way it s not Java Box2D is the original library written in C++ . Your code is an example of using that library . JBox2D is a Java wrapper of the C++ library so you can write Java code that interacts with the C++ library . Processing is written in Java so you can use JBox2D in Processing . Processing also has a few libraries that simplify JBox2D like Daniel Shiffman s Box2D for Processing https : github.com shiffman Box2D-for-Processing or BoxWrap2d http : www.jbox2d.org processing doc index.html org jbox2d p5 Physics.html . You don t need to use these libraries in order to use JBox2D from Processing . .. . .. . You can find the documentation for JBox2D here https : github.com jbox2d jbox2d . To answer your question yes the world variable would be the instance of World you created when you set up your physics environment . If you re using one of the Processing libraries the creation of the World instance might be hidden from you . You might have to use JBox2D directly yourself .

Balls can collide with one another and a ring of circles keys around the edge of the sketch . Every time you click a ball object is added to an array list . Everything works fine until you start clicking rapidly creating many balls in a short period of time .

The simulation runs incrementally and in between the updates the contents of the simulation are supposed to be drawn . Similar to a game except without input . I only need geometric primitives to draw a JBox2D simulation . This API seemed like the simplest choice but its design is a bit confusing . Currently I have one class called Window extending JFrame that contains as a member another class called Renderer . The Window class only initializes itself and provides an updateDisplay method that is called by the main loop that calls updateDisplay objects method on the Renderer . I made these two methods myself and their only purpose is to call repaint on the Renderer . Is the JPanel supposed to be used that way Or am I supposed to use some more sophisticated method for animation such that involves events and or time intervals in some back-end thread .. .

Comment : What is your question Java port did not updated yet to the last Box2D version it is obvious . Only way to fix this - make your best and do it yourself or wait while someone will update jbox2d . Comment : From what I recall reading Box2D v2.1 was released in 2011...why is it taking so long There s no way I can do it myself but I did ask the creator and he never wrote back so I m guessing he doesn t know either .. . Answer : If you want the 2.2.1 version of jbox2d you can grab a build from the trunk https : code.google.com p jbox2d source checkout . It s almost ready for a release I just need to do a bit more optimization and inlining . edit : It looks like libgdx uses it s own wrappers to a the native C++ implementation of Box2D . This is definitely preferable performance-wise hopefully they will update their library ." ] }

Answer : It seems that nobody ported Candescent NUI to Kinect v2 . You can do it by yourself . His code is pretty good and clear . A number of months ago I really wanted to port this code to Kinect v2 even started working on that but realized that I don t want front face finger tracking but top-down something more similar to RetroDepth https : www.youtube.com watch v 96CZ QPBx0s and now I am implementing this . If you only need a finger tracking similar to Leap Motion you may use Nimble SDK it works pretty well not perfectly with Kinect v2 in front facing mode like Candescent does but it gives use full 3d hand skeleton . With Kinect v1 it works using top-down setup . But I am not sure if they still provide free licenses . Check it . If they don t provide free license you can either re-implement Candescent hand tracking features moreover you could do it more robust so it could support another depth cameras with different range near far and different resolutions actually one of the most annoying things in my opinion that Candescent has it s hard coded resolution of depth and color images . Moreover on the CHI2015 http : chi2015.acm.org will be presented a new technique for hand tracking for Kinect v2 by Microsoft https : www.youtube.com watch v A-xXrMpOHyc maybe they will integrate it soon into Kinect SDK v2 .

If you select your text field in the IB and look at its outlets you should see something like the below where it has a Referencing Outlet to the view controller s view property .

You can download the SDK freely but the v2-sensor may cost a little .", "Question : For the past few months I ve been looking into developing a Kinect based multitouch interface for a variety of software music synthesizers . The overall strategy I ve come up with is to create objects either programatically or if possible algorithmically to represent various controls of the soft synth . These should have .. . .. . X position .. . Y position .. . Height .. . Width .. . MIDI output channel .. . MIDI data scaler convert x-y coords to midi values .. . .. . 2 strategies I ve considered for agorithmic creation are XML description and somehow pulling stuff right off the screen ie given a running program find xycoords of all controls . I have no idea how to go about that second one which is why I express it in such specific technical language . I could do some intermediate solution like using mouse clicks on the corners of controls to generate an xml file . Another thing I could do that I ve seen frequently in flash apps is to put the screen-size into a variable and use math to build all interface objects in terms of screen-size . Note that it isn t strictly necessary to make the objects the same size as onscreen controls or to represent all onscreen objects some are just indicators not interactive controls .. . .. . Other considerations .. . .. . Given for now two sets of X Y coords as input left and right hands what is my best option for using them My first instinct is was to create some kind of focus test where if the x y coords fall within the interface object s bounds that object becomes active and then becomes inactive if they fall outside some other smaller bounds for some period of time . The cheap solution I found was to use the left hand as the pointer selector and the right as a controller but it seems like I can do more . I have a few gesture solutions hidden markov-chains I could screw around with . Not that they d be easy to get to work exactly but it s something I could see myself doing given sufficient incentive . So to summarize the problem is .. . .. . represent the interface necessary because the default interface always expects mouse input .. . select a control .. . manipulate it using two sets of x y coords rotary continuous controller or in the case of switches preferrably use a gesture to switch it without giving taking focus . Any comments especially from people who have worked are working in multitouch io NUI are greatly appreciated . Links to existing projects and or some good reading material books sites etc would be a big help . Comment : Meta-discussion about this question is happening has happened : meta.stackexchange.com q 106720 146495 http : meta.stackexchange.com q 106720 146495 .. . Answer : Woah lots of stuff here . I worked on lots of NUI stuff during my at Microsoft so let s see what we can do.. . But first I need to get this pet peeve out of the way : You say Kinect based multitouch . That s just wrong . Kinect inherently has nothing to do with touch which is why you have the select a control challenge . The types of UI consideration needed for touch body tracking and mouse are totally different . For example in touch UI you have to be very careful about resizing things based on screen-size resolution DPI.. . regardless of the screen fingers are always the same physical size and people have the same degreee of physical accuracy so you want your buttons and similar controls to always be roughly the same physical size . Research has found 3 4 of an inch to be the sweet spot for touchscreen buttons . This isn t so much of a concern with Kinect though since you aren t directly touching anything - accuracy is dictated not by finger size but by sensor accuracy and users ability to precisely control finicky lagging virtual cursors . If you spend time playing with Kinect games it quickly becomes clear that there are 4 interaction paradigms . 1 Pose-based commands . User strikes and holds a pose to invoke some application-wide or command usually brining up a menu 2 Hover buttons . User moves a virtual cursor over a button and holds still for a certain period of time to select the button 3 Swipe-based navigation and selection . User waves their hands in one direction to scroll and list and another direction to select from the list 4 Voice commands . User just speaks a command . There are other mouse-like ideas that have been tried by hobbyists havent seen these in an actual game but frankly they suck : 1 using one hand for cursor and another hand to click where the cursor is or 2 using z-coordinate of the hand to determine whether to click .. . .. . It s not clear to me whether you are asking about how to make some existing mouse widgets work with Kinect . If so there are some projects on the web that will show you how to control the mouse with Kinect input but that s lame . It may sound super cool but you re really not at all taking advantage of what the device does best . If I was building a music synthesizer I would focus on approach 3 - swiping . Something like Dance Central . On the left side of the screen show a list of your MIDI controllers with some small visual indication of their status . Let the user swipe their left hand to scroll through and select a controller from this list . On the right side of the screen show how you are tracking the users right hand within some plane in front of their body . Now you re letting them use both hands at the same time giving immediate visual feedback of how each hand is being interpretted and not requiring them to be super precise . ps.. . I d also like to give a shout out to Josh Blake s upcomming NUI book . It s good stuff . If you really want to master this area go order a copy : http : www.manning.com blake Comment : Robert - thanks a bunch for your answer good to see an ex-microsoft guy onboard . First re kinect vs multitouch . I started out screwing around with various blob-tracking solutions awhile back and gave up because when lighting conditions changed by the smallest margin imaginable system response slowed to a crawl . I got into kinect because it handles blob tracking internally and outputs one or more x y cursor coords . I have found that the resolution problem you mention if we re talking about the same thing still obtains for kinect because display resolutions and interface sizes differ . Comment : Re mouse the middleware I am using primesense nite essentially outputs 2 cursors in hand mode as well as a gesture-based click pushing your hand toward the screen . I can use all of the joints it outputs 10 or so knees hips etc if I so choose tho I haven t felt like it yet . Re your swipe that is the best I could actually come up with on my own . I am hoping other people have better ideas . Comment : Here s an example of what I consider better - anythinghonest.com amos http : anythinghonest.com amos . It uses all the available features of the new tech ipad in this case in an intuitive way while providing deep control . I may steal parts of it for my thing . Thanks again for your help . Joe Comment : I m also aware of that book - looks pretty awsome will have to pick it up .", "Question : I ve got a strange problem . I m creating a NUI for application and I binded some simple gestures to right and left arrow . The problem is when I start application .

I m comparing timestamp of invoking the code and timestamp of last gesture-recognition . If its too fast i meen couple of ms which it impossible to make I don t allow to hit an arrow . I m not sure if it s a perfect solution but it is a working solution Comment : It is not very easy to follow you but usually such things happen when something is wrong with initialization code . Comment : @AndriyBuday its hard to fallow cause the problem is strange and its hard to describe it . If you need more info just say what you need and I ll try to add it . About the initialization . ArrayList are initialized on start of the program : private List HistoryItem history new List HistoryItem 16 nothing else Comment : You should probably paste a little more code to show the transitions . Also as the problem is likely to be in the init code could you summarize what you put in there Comment : @PPC added more code . Comment : what do you mean the application is hitting two times in a row .. . Answer : Ok my problem was the code . Ofc a small bug untracable in the debug . I used one function to analyse a history of frames . The method was working in 2 modes .

Assuming that I have an ellipse on my Grid or Canvas I should be able to pick an ellipse using my program . In order to do this I thought that I have to determine the exact position of the element like Transform.Position in Unity but I couldn t find such a thing in WPF . Here is my XAML code .. . .. . So my question is about finding the that element on the Grid . Having a Cursor or any element that represents the user s hand is not a problem . But after that I ll have to detect the collision between my cursor and these elements and that the part that troubles me . An event like ElementHover or ElementPicked would also help but i guess i m gonna have to write something like that myself . By the way it s about an Engineering Education Software project that aims to develop virtual environments for engineering exercises like expensive or dangerous experiments . .. . Answer : Several examples from Microsoft provided in the SDK v1.6 Toolkit give examples of how to determine the location of objects on the screen and interact with them with a custom cursor that represents the player s hand . I would suggest checking out several of the examples provided in order to get a clear picture of how interactions can work . The toolkit is found in the same location as the office Kinect for Windows SDK . http : www.microsoft.com en-us kinectforwindows develop developer-downloads.aspx .. . .. . ShapeGame .. . .. . This example generates random shapes some of them ellipses which fall from the top of the window . Those shapes interact with the skeleton produced by the Kinect . You ll see how to get the position of elements in the window and in relation to the skeleton . BasicInteractions .. . .. . This examples does several things that are of use . It shows how to produce a custom cursors based on the hand position . It also creates a ContentControl that can be hooked up to Kinect events such as a hand enter hover and exit event . It is built-in such a way because it is a ContentControl that anything can be put inside -- be it a single ellipse or a complex layout .

Thanx man .", "Question : I need to write applications with NUI for multiple simultaneous users . I have the following options : .. . .. . 1 . OpenGL .. . 2 . Microsoft Surface SDK .. . 3 . Microsoft Windows 8.1 RT .. . .. . Of the above three options I believe that with OpenGL I can write my programs but I am confused about the other two . With Microsoft Surface SDK 2.0 I am unable to confirm that it can be used with third-party multitouch enabled devices with are Windows 7 8 ready . And also will the application only run on Windows 7 platform or will it also run on Windows 8.x platform too How will I be able to deploy Microsoft Surface SDK 2.0 application on the third-party device Microsoft Windows 8.1 RT does support multitouch gestures but I can t find anything concrete on its limitations of the number of simultaneous touches . So I would like help on getting more info on writing Microsoft SDK 2.0 application for third-party devices . .. . Answer : The Surface 2.0 SDK is essentially a set of DLLs that you reference and deploy with your app . They will work on Win7 8 and 8.1 . They are for building desktop apps though as opposed to modern apps which play nicely with things in Win8 like swiping to switch apps . Comment : And can I also leverage the power of multi-user multi-touch gesture of Surface SDK 2.0 in the apps written for Win 7 8.x too Comment : Surface 2.0 SDK is basically going to give you a bunch of WPF controls that are touch-friendly and support multiple users . If you just want the basic gesture APIs those manipulation events are built into WPF 4 taken out of the Surface 1.0 SDK and also built into the modern Win8 UI frameworks . The controls in the Win8 UI frameworks are touch-friendly but not for multiuser you can t press 2 buttons at the same time for example Comment : Thank you Robert Your answers were of great help and now I d need to go forward with using Surface SDK 2.0 as I need to leverage its multiuser features .", "Question : I am working with Kynect + Python without using Micosoft visual-studio on windows-7 . Does anybody know how to get frames from Kinect without using an event-loop I am refering to this method of PyKinect nui init .py .. . .. .

How can I do this I am using the following environment and versions : .. . .. . Python 2.7.2 .. . PyKinect 2.1b1 .. . Kinect sensor from XBOX v1 .. . Kinect SDK 1.8 .. . Windows 7 .. . Answer : You cannot get RGB or depth or skeleton frame on demand . Kinect data are provided by events so you have to use them to got data . The only thing that you can do to workaround this event-based system is to save your data in a global variable and then read that variable whenever you need it . For instance let s say that you associate a function named depth frame ready to the event related to depth data : .. . .. . You can write the depth frame ready function to save data on a global variable let s say depth data . You will also need a synchronization mechanism to read and write that variable a simple Lock to avoid simultaneously writing and reading : .. . .. .

Comment : How much is 1 LSB Is it 1 Bit Comment : @Hedge Least Significant Bit - the lowest valued bit in your bit pattern i.e . 1 if the value is not floating-point", "Question : I m currently in the early stages of a project and have difficulty deciding which framework to use . I hear people say WPF is dead yet it seems to be the only way to program a Microsoft Surface app . This is one of the possible future aims of the project but not the main focus . The main focus however is : both 2d and 3d objects in the same view and kinect voice support . Some of the 2d objects are SVG files . From what I have read online so far it s not easy to render SVG graphics in XNA nor Silverlight 5 3D for that matter . I ve seen some SVG to XAML converters but could the result-of this be used in a 3d view Or vice versa Considering it s not going to be a game but a business-application I m tempted to rule out XNA but then again I also require good performance as there will be quite some graphical stuff going on and if possible support for high resolutions video wall . Taking a video wall into consideration would maybe rule out WPF as I ve read that it will only use hardware-acceleration if the resolution is lower than the texture size limit of the GPU . There is no intend to run the application in the browser or phone as such i m tempted to rule out Silverlight 5 . Any tips would be greatly be appreciated . Thanks Comment : Not only is WPF dead but so is Silverlight and WinForms I m pretty sure HTML 5 is the only technology not dead yet . Good luck doing 3D with it though . Comment : @gabe Well let s not call it all dead yet . Before the HTML 5 standard is actually done accepted and all browsers support it we will be 5 or more years further down the road . Comment : LOL @Gabe . You forgot to mention compilers and all compiled languages are dead too .. . Answer : I wouldn t rule out XNA on the basis that it s for games . You can simply use only the parts required for hardware-accelerated 3D rendering and ignore the rest . This is in fact what Silverlight 5 does So you may find that your 3D rendering code is the same between XNA and SL5 in any case . Here is a question about SVG in XNA http : gamedev.stackexchange.com questions 2196 rendering-svg-art-directly-in-xna . Basically answer is : you have to write your own hardware-accelerated SVG renderer - a stupidly difficult task . But if your SVG files never change you could just use an existing software renderer to render them to a texture . If you converted your SVG to XAML you would have to render it to a texture to use it in a SL5 3D view anyway unless it s an overlay . So there is no big win there . I don t know how 2D-3D compositing works in WPF . Your decision really depends on whether you would find the built-in functionality that SL5 or WPF provides for user interfaces useful Seeing as you are basically making your own user-interface you probably would not get much use from the provided 2D interface . The 3D API that SL5 provides is basically a cut-down version of XNA . The 3D API for WPF looks like it just renders models for you - it does not seem to buy you much over XNA . If you have a compelling reason to use XAML then WPF may be a good choice . Otherwise I d go with XNA .", "Question : I have some problem with the kinect . when I try to get color Image from the event : Sensor AllFramesReady everything is ok . example : .. . .. .

Answer : A std : : string s allocation is not guaranteed to be contiguous under the C++98 03 standard but C++11 forces it to be . In practice neither I nor Herb Sutter http : herbsutter.wordpress.com 2008 04 07 cringe-not-vectors-are-guaranteed-to-be-contiguous know of an implementation that does not use contiguous storage . Notice that the s 0 thing is always guaranteed to work by the C++11 standard even in the 0-length string case . It would not be guaranteed if you did str.begin or str.begin but for s 0 the standard defines operator as : .. . .. . Returns : begin + pos if pos size otherwise a reference to an object of type T with value charT the referenced value shall not be modified .. . .. . Continuing on data is defined as : .. . .. . Returns : A pointer p such that p + i operator i for each i in 0 size . notice the square brackets at both ends of the range .. . .. . .. . .. . Notice : pre-standardization C++0x did not guarantee s 0 to work with zero-length strings actually it was explicitly undefined-behavior and an older revision of this answer explained this this has been fixed in later standard drafts so the answer has been updated accordingly . Comment : I have not been following the standard for the last few months but it was my impression was this was still in the 0x draft and therefor not actually yet required or will be if a library chooses to only implemented 03 . Comment : Sutter says in a comment to that post current ISO C++ does require str 0 to cough up a pointer to contiguous string data but not necessarily null-terminated which would in fact make the OP s usage correct . However I can t find anything that says that in the standard at least it s not in 21.3.4 lib.string.access . Comment : I think that might be right the std defect 530 says operator is contiguous but the iterator interface is not guaranteed to be and quotes 23.4.4 . I am digging out my standard to check . Comment : I skipped right over the defect link in Sutter s post that s why I missed it . In any case the defect says we almost require contiguity already key word : almost and I don t see how its reference to multiset is relevant basic string is a sequence with random-access iterators . However I think the important thing to take away is that given the existence of data and the definition of operator and at in terms of data I don t believe it s possible to write a useful and standard- conforming basic string that isn t contiguous . Comment : James : the almost is because the null for s s.length does not have to be contiguous . s n + 1 s n + 1 must be true for all n where 0 n s.length - 1 . The requirement is buried in 21.3.4 1 that s n must return the same object as s.data n for n length and data must be contiguous .", "Question : Is it possible for C++ code to conform to both the C++03 http : en.wikipedia.org wiki C++03 standard and the C++11 http : en.wikipedia.org wiki C++11 standard but do different things depending on under which standard it is being compiled Comment : I m pretty sure auto could result in a situation like this Comment : Yes .

Comment : Closing this as too broad would be a shame this is question likely to be asked many times and it would be good to have a solid canonical question to point to that is not closed . .. . Answer : One potentially dangerous backward-incompatible change is in constructors of sequence containers such as std : : vector specifically in the overload specifying initial size . Where in C++03 they copied a default-constructed element in C++11 they default-construct each one . Consider this example using boost : : shared-ptr so that it s valid C++03 : .. . .. . C++03 Live example http : coliru.stacked-crooked.com a 426fb7a77f020e4b .. . .. . C++11 Live example http : coliru.stacked-crooked.com a 201f0609fec61325 .. . .. . The reason is that C++03 specified one overload for both specify size and prototype element and specify size only like this allocator arguments omitted for brevity : .. . .. . This will always copy prototype into the container size times . When called with just one argument it will therefore create size copies of a default-constructed element . In C++11 this constructor signature was removed and replaced with these two overloads : .. . .. . The second one works as before creating size copies of the prototype element . However the first one which now handles calls with only the size argument specified default-constructs each element individually . My guess for the reason of this change is that the C++03 overload wouldn t be usable with a move-only element type . But it s a breaking change none the less and one seldom documented at that . Comment : While this is obviously a breaking change I prefer the C++11 behaviour .

Removing the implementation defined part of the operator is a consequence of that . Comment : @moswald : you would have to avoid using operator in those cases as well since it is similarly implementation defined . .. . Answer : The algorithm says a b b + a b a which is easier to read if you remember that it s truncate a b b + a b a Using algebra a b a - truncate a b b . That is to say f a b a - truncate a b b . For what values is f a b 0 It doesn t matter if b is negative or positive . It cancels itself out because it appears in the numerator and the denominator . Even if truncate a b 0 and b is negative well it s going to be canceled out when it s a product of 0 . Therefore it is only the sign of a that determines the sign of f a b or a b .

Comment : Closing this as too broad would be a shame this is question likely to be asked many times and it would be good to have a solid canonical question to point to that is not closed . .. . Answer : Yes there are number of changes that will cause the same code to result in different behavior between C++03 and C++11 . The sequencing rules differences make for some interesting changes including some previously undefined-behavior becoming well defined . 1 . multiple mutations of the same variable within an initializer-list .. . .. . One very interesting corner case would multiple mutations of the same variable within an initializer-list for example : .. . .. . In both C++03 and C++11 this is well defined but the order of evaluation in C++03 is unspecified http : stackoverflow.com questions 19881803 are-multiple-mutations-of-the-same-variable-within-initializer-lists-undefined-b but in C++11 they are evaluated in the order in which they appear http : stackoverflow.com questions 14442894 are-multiple-mutations-within-initializer-lists-undefined-behavior . So if we compile using clang in C++03 mode it provide the following warning see it live http : coliru.stacked-crooked.com a 906eb652c8852d7a : .. . .. . but does not provide a warning in C++11 see it live http : coliru.stacked-crooked.com a f64b518da84ecc4e . 2 . New sequencing rules make i ++ i + 1 well defined in C++11 .. . .. . The new sequencing rules adopted after C++03 means that : .. . .. . is no longer undefined-behavior in C++11 this is covered in defect report 637 . Sequencing rules and example disagree http : www.open-std.org jtc1 sc22 wg21 docs cwg defects.html 637 .. . .. . 3 . New sequencing rules also make ++++i well defined in C++11 .. . .. . The new sequencing rules adopted after C++03 means that : .. . .. . is no longer undefined-behavior in C++11 . 4 . Slightly More Sensible Signed Left-Shifts .. . .. . Later drafts of C++11 include N3485 which I link below fixed the undefined-behavior of shifting a 1 bit into or past the sign bit http : blog.regehr.org archives 738 . This is also covered in defect report 1457 http : www.open-std.org jtc1 sc22 wg21 docs papers 2012 n3367.html 1457 . Howard Hinnant commented on the significance of this change in the thread on Is left-shifting a negative integer undefined-behavior in C++11 http : stackoverflow.com questions 19593938 is-left-shifting-a-negative-integer-undefined-behavior-in-c11 comment29091986 19593938 . 5 . constexpr functions can be treated as compile-time constant expressions in C++11 .. . .. . C++11 introduced constexpr http : en.cppreference.com w cpp language constexpr functions which : .. . .. . The constexpr specifier declares that it is possible to evaluate the value of the function or variable at compile-time . Such variables and functions can then be used where only compile-time constant expressions are allowed . while C++03 does not have the constexpr feature we don t have to explicitly use the constexpr keyword since the standard-library provides many functions in C++11 as constexpr . For example std : : numeric limits : : min http : en.cppreference.com w cpp types numeric limits min . Which can lead to different behavior for example : .. . .. . Using clang in C++03 this will cause x to be a variable-length array which is an extension http : clang.llvm.org compatibility.html vla and will generate the following warning : .. . .. . while in C++11 std : : numeric limits unsigned int : : min +2 is a compile-time constant-expression and does not require the VLA extension . 6 . In C++11 noexcept exception specifications are implicitly generated for your destructors .. . .. . Since in C++11 user defined destructor has implicit noexcept true specification as explained in noexcept destructors http : akrzemi1.wordpress.com 2013 08 20 noexcept-destructors it means that the following program : .. . .. . In C++11 will call std : : terminate but will run successfully in C++03 . 7 . In C++03 template arguments could not have internal linkage .. . .. . This is covered nicely in Why std : : sort doesn t accept Compare classes declared within a function http : stackoverflow.com a 14596065 1708801 . So the following code should not work in C++03 : .. . .. . but currently clang allows this code in C++03 mode with a warning unless you use -pedantic-errors flag which is kind of icky see it live http : coliru.stacked-crooked.com a 316202b3a33a8ec6 . 8 . is not longer ill-formed when closing multiple templates .. . .. . Using to close multiple templates is no longer ill-formed but can lead to code with different results in C++03 and C+11 . The example below is taken from Right angle brackets and backwards compatibility http : dev.krzaq.cc right-angle-brackets-and-backwards-compatibility : .. . .. . and the result in C++03 is : .. . .. . and in C++11 : .. . .. . 9 . C++11 changes some of std : : vector constructors .. . .. . Slightly modified code from this answer http : stackoverflow.com a 6474857 1708801 shows that using the following constructor from std : : vector http : en.cppreference.com w cpp container vector vector : .. . .. . produces different results in C++03 and C++11 : .. . .. . 10 . Narrowing conversions in aggregate initializers .. . .. . In C++11 a narrowing conversion in aggregate initializers is ill-formed and it looks like gcc allows this in both C++11 and C++03 although it provide a warning by default in C++11 : .. . .. . This is covered in the draft C++11 standard section 8.5.4 List-initialization paragraph 3 : .. . .. . List-initialization of an object or reference of type T is defined as follows : .. . .. . and contains the following bullet emphasis mine : .. . .. . Otherwise if T is a class type constructors are considered . The applicable constructors are enumerated and the best one is chosen through overload-resolution 13.3 13.3.1.7 . If a narrowing conversion see below is required to convert any of the arguments the program is ill-formed .. . .. . This and many more instance are covered in the draft C++ standard http : www.open-std.org jtc1 sc22 wg21 docs papers 2012 n3485.pdf section annex C.2 C++ and ISO C++ 2003 . It also includes : .. . .. . New kinds of string-literals .. . Specifically macros named R u8 u8R u uR U UR or LR will not be expanded when adjacent to a string literal but will be interpreted as part of the string literal . For example .. . .. . define u8 abc .. . const char s u8 def Previously abcdef now def .. . .. . .. . User-defined literal string support .. . Previously 1 would have consisted of two separate preprocessing tokens and the macro x would have been expanded . In this International Standard 1 consists of a single preprocessing tokens so the macro is not expanded . define x there .. . hello x 1 .. . .. . .. . Specify rounding for results of integer and .. . 2003 code that uses integer-division rounds the result toward 0 or toward negative infinity whereas this International Standard always rounds the result toward 0 . Complexity of size member-functions now constant .. . Some container implementations that conform to C++ 2003 may not conform to the specified size requirements in this International Standard . Adjusting containers such as std : : list to the stricter requirements may require incompatible changes . Change base-class of std : : ios base : : failure .. . std : : ios base : : failure is no longer derived directly from std : : exception but is now derived from std : : system error which in turn is derived from std : : runtime-error . Valid C++ 2003 code that assumes that std : : ios base : : failure is derived directly from std : : exception may execute differently in this International Standard . Comment : So most of the examples narrow down to the fact that previously undefined behaviour is now well defined Comment : @MatthiasB 2 3 and 4 are about this so at this point they are not a majority of the examples anymore . I doubt I will find many more undefined-behavior examples so as I add more then they will become a smaller set . Comment : Well 1 behaviour is unspecified so i d count it as undefined behaviour at least you cannot expect to get a specific result with c++03 now with c++11 you can 5 uses a non-standard extension of c++ . But I guess you re right . The more you look for it the more examples you ll find which are defined in both standards but produce different results . Comment : @MatthiasB yes both unspecified and undefined-behavior have undesirable results .

Answer : The behaviour of was tightened in C++11 and is now fully specified apart from division by 0 .

The mathematical reason for this is as follows : .. . .. . Let be mathematical division and be C++ division . For any a and b we have a b a b + f where f is the fractional part and from the standard we also have a b b + a b a . a b is known to truncate towards 0 so we know that the fractional part will always be positive if a b is positive and negative is a b is negative : .. . .. . sign f sign a sign b .. . .. . a b a b + f can be rearranged to give a b a b - f . a can be expanded as a b b : .. . .. . a b b + a b a a b - f b+a b a b b .

I understood that the Unicode code points were minimized to make all of the UTF-8 UTF-16 and UTF-32 encodings able to handle the same number of code points . But what is this number of code points The most frequent answer I encountered is that Unicode code points are in the range of 0x000000 to 0x10FFFF 1 114 112 code points but I have also read in other places that it is 1 112 114 code points . So is there a one number to be given or is the issue more complicated than that Comment : possible duplicate of How many characters can be mapped with Unicode http : stackoverflow.com questions 5924105 how-many-characters-can-be-mapped-with-unicode .. . Answer : yes all the code points that can t be represented in UTF-16 including using surrogates have been declared invalid . U+10FFD seems to be the higest code point but the surrogates u+00FFFE and u+00FFFF aren t usable code points so the total count is a bit lower .", "Question : In Unicode what is the difference between composite characters and surrogate-pairs To me they sound like similar things - two characters to represent one character . What differentiates these two concepts .. . Answer : Surrogate pairs are a weird wart in Unicode . Unicode itself is nothing other than an abstract assignment of meaning to numbers . That s what an encoding is . Capital-letter-A Greek-alternate-terminal-sigma Klingon-closing-bracket-2 etc . currently numbers up to about 221 are available though not all are in use . In the context of Unicode each number is know as a code point . However the Unicode suite as a whole contains more than just this encoding . It also contains technologies to serialize code points . This is essentially just an exercise in serializing unsigned integers . Three subfamilies of technologies are specified : UTF-32 UTF-8 and UTF-16 . UTF-32 simply expresses every code-point as a 32-bit unsigned-integer . That s easy . Two variants exist for big and little endian respectively . Each 32-bit serialized integer is called the code unit of this format and this is a fixed-width format one code point per code unit . UTF-8 is a clever multi-byte format in which code points take up anything from one to six 8-bit bytes . This format is very portable since it has no ordering issues and since it is pretty compact for English near-English and computer code . The code unit of UTF-8 is one byte and this is a variable-width format 1 6 code units per code point . Finally there s UTF-16 : Initially people thought Unicode could do with only 216 numbers so this was initially deemed to be fixed-width with 16-bit code units . However it eventually became clear that we needed larger numbers . So UTF-16 is now also a variable-width format but the way this is achieved is that certain 16-bit code units act as indicators that they are part of a two-unit pair the surrogate pair . However to simplify the way you detect those pairs rather than having some external envelope format as UTF-8 does the actual 16-bit values that are used by the surrogates are deliberately leaked back into the Unicode encoding and left out of the encoding - that is the surrogate values 0xD800 to 0xDFFF are not valid Unicode code points . So in summary surrogates are the result-of forcing a serialization format for Unicode back into the encoding and distorting the design of the encoding to accommodate the serialization format . This is perhaps an unfortunate historical accident which is somewhat pointless and unsightly in retrospect but it s what we have and what we need to live with . .. . .. . Composite characters on the other hand are something much higher-level : They are visual units graphemes that are composed of multiple Unicode code points . Sometimes people refer to code points themselves as characters but that s a little bit misleading since characters should really be graphemes and they can consist of several components e.g . a base letter plus diacritics and modifiers .

However if you think of the underlying language of source symbols being graphemes things get a lot more complicated . So my question is this in the sense of graphemes is UTF-32 truly a fixed length encoding And if not is there a possible fixed length encoding in that sense Comment : Read this : The Absolute Minimum Every Software Developer Absolutely Positively Must Know About Unicode and Character Sets No Excuses http : www.joelonsoftware.com articles Unicode.html .

Just like UTF-8 isn t fixed width some Unicode characters code points require one 8-bit code units others require two three or even four 8-bit code units .

Answer : One of the comments referenced Joel Spolsky s The Absolute Minimum Every Software Developer Absolutely Positively Must Know About Unicode and Character Sets No Excuses http : www.joelonsoftware.com articles Unicode.html article which was written in 2003 . At the time it served as a wake-up call it probably still does in some places . However it is not without its minor but significant technical problems though the overall thesis you need to know about Unicode and you need to know which encoding a string is in remains valid . The comment then continued : .. . .. . And yes UTF-16 and UTF-32 are both fixed width . UTF-8 isn t . UTF-16 isn t really fixed width some Unicode code points are one 16-bit code unit others require two 16-bit code units just like UTF-8 isn t fixed width some Unicode code points require one 8-bit code units others require two three or even four 8-bit code units but not five or six despite the comment from Joel s article that mentions the possibility . UTF-32 on the other hand is fixed width all Unicode code points can be encoded in a single 32-bit code unit . Indeed the maximum possible Unicode code point is U+10FFFF so Unicode is a 21-bit code set though it does not use all possible combinations of 21 bits . However code points are not identical to characters let alone graphemes . The Unicode FAQ has a section on Characters and Combining Marks http : unicode.org faq char combmark.html discusses graphemes referencing the glossary http : www.unicode.org glossary grapheme definition . The better word for what end-users think of as characters is grapheme as defined in the Unicode glossary : a minimally distinctive unit of writing in the context of a particular writing system . .. . Graphemes are not necessarily combining character sequences and combining character sequences are not necessarily graphemes . .. . Q : How are characters counted when measuring the length or position of a character in a string http : unicode.org faq char combmark.html 7 .. . .. . A : Computing the length or position of a character in a Unicode string can be a little complicated as there are four different approaches to doing so plus the potential confusion caused by combining characters . The correct choice of which counting method to use depends on what is being counted and what the count or position is used for . To address the question here : .. . .. . If you mean something to do with it can take multiple Unicode code points to get a complete character grapheme with associated diacritics combining markers etc . then yes even UTF-32 isn t necessarily fixed width and there is no fixed width encoding for Unicode . UTF-32 employs a fixed-width encoding for each Unicode code point but since it can take multiple code points to create a complete grapheme even UTF-32 does not have a 1 : 1 mapping between code points and graphemes . Of course you can also find interesting character stacks in some comments on SO . For example : .. . .. . .. . .. . .. . .. . @ s e r n m e B l a b l h b a h . . . .. . .. . .. . .. . .. . .. . Why how do Zalgo pings work http : meta.stackoverflow.com questions 266912 why-how-do-zalgo-pings-work .. . .. .

What you see of course depends on the quality of the Unicode support in your browser which in turn depends in part on the quality of the O S support . I get to see different results on two different Macs running rather different versions of Firefox even they re running the same base O S version 10.10.4 Yosemite . The second of those examples can be decoded from UTF-8 into the following sequence of Unicode code points it is only 700 bytes on disk : .. . .. . It gets tricky to decipher which parts of that are graphemes but clearly with all the stacked characters this is not a fixed amount of data per grapheme and there is no sane way to make Unicode work with a fixed width encoding per grapheme because as the Zalgo examples show combining-marks can basically be combined in arbitrary sequences . The first grapheme in the second Zalgo example contains : .. . .. . The next code point is U+0078 LATIN SMALL LETTER X the start of a new grapheme . A couple of the combining-marks appear several times each in that list . Comment : Joel s article might have been a great read but it s sadly riddled with small mistakes like the one you pointed out . Of the top of my head there s also the claim that UTF-8 goes up to 6 bytes which is severely outdated Comment : @R.MartinhoFernandes Yes that s why I don t recommend it although I am sad not to . I don t understand why he doesn t fix it . Comment : @tchrist : I ve revised the commentary on Joel s article in part in the light of your comment and R . Martinho Fernandes s comment . It mentions UTF-7 which I ve not seen serious discussion or use of in a long time . Wikipedia says UTF-7 https : en.wikipedia.org wiki UTF-7 was an experimental protocol defined by some RFCs that were never officially Internet Standards and UTF-7 was never a Unicode standard either and apparently the Internet Mail Consortium recommends against using it . Comment : I think you might want to note explicitly why a fixed length encoding is impossible namely that you can stack combining-marks infinitely But all around a beautiful answer I ll mark it as accepted shortly .", "Question : I have read many articles in order to know what is the maximum number of the Unicode code points but I did not find a final answer . I understood that the Unicode code points were minimized to make all of the UTF-8 UTF-16 and UTF-32 encodings able to handle the same number of code points . But what is this number of code points The most frequent answer I encountered is that Unicode code points are in the range of 0x000000 to 0x10FFFF 1 114 112 code points but I have also read in other places that it is 1 112 114 code points . So is there a one number to be given or is the issue more complicated than that Comment : possible duplicate of How many characters can be mapped with Unicode http : stackoverflow.com questions 5924105 how-many-characters-can-be-mapped-with-unicode .. . Answer : The maximum valid code point in Unicode is U+10FFFF which makes it a 21-bit code set but not all 21-bit integers are valid Unicode code points specifically the values from 0x11000 to 0x1FFFF are not valid Unicode code points . This is where the number 1 114 112 comes from : U+0000 . . U+10FFFF is 1 114 112 values . However there are also a set of code points that are the surrogates for UTF-16 . These are in the range U+D800 . . U+DFFF . This is 2048 code points that are reserved for UTF-16 . 1 114 112 - 2 048 1 112 064 .. . .. . There are also 66 non-characters . These are defined in part in Corrigendum 9 http : www.unicode.org versions corrigendum9.html : 34 values of the form U+nFFFE and U+nFFFF where n is a value 0x00000 0x10000 0xF0000 0x100000 and 32 values U+FDD0 - U+FDEF . Subtracting those too yields 1 111 998 allocatable characters . There are three ranges reserved for private use : U+E000 . . U+F8FF U+F0000 . . U+FFFFD and U+100000 . . U+10FFFD . And the number of values actually assigned depends on the version of Unicode you re looking at . You can find information about the latest version at the Unicode Consortium http : unicode.org versions latest . Amongst other things the Introduction there says : .. . .. . The Unicode Standard Version 7.0 contains 112 956 characters .. . .. . So only about 10 of the available code points have been allocated . I can t account for why you found 1 112 114 as the number of code points . Incidentally the upper limit U+10FFFF is chosen so that all the values in Unicode can be represented in one or two 2-byte coding units in UTF-16 using one high surrogate and one low surrogate to represent values outside the BMP or Basic Multilingual Plane which is the range U+0000 . . U+FFFF . Comment : 1 112 114 look like a typo it a the 000000..10FFFF count with the 2 and 4 transposed . Comment : @user313114 : I suppose it could be a compound typo as you suggest that is at least better than no explanation which is roughly what I ve got at the moment . I could make efforts to account for slightly smaller numbers of characters than the 1 112 064 but not for slightly larger .

Unicode code points are limited to 21 bits which limits UTF-8 to 4 bytes . You could of course extend the principle of UTF-8 to encode arbitrary large integers but it would not be Unicode . See RFC 3629 .", "Question : I ve never understood the point of UTF-16 encoding . If you need to be able to treat strings as random-access i.e . a code point is the same as a code unit then you need UTF-32 since UTF-16 is still variable-length . If you don t need this then UTF-16 seems like a colossal waste of space compared to UTF-8 . What are the advantages of UTF-16 over UTF-8 and UTF-32 and why do Windows and Java use it as their native encoding Comment : Perhaps you could rephrase your question to not be so subjective and argumentative Comment : If only it was true for UTF-32.. . Play 5 minutes with combining characters en.wikipedia.org wiki Combining character http : en.wikipedia.org wiki Combining character and the tell me how much random everything is : - .. . Answer : UTF-16 allows all of the basic multilingual plane BMP to be represented as single code units . Unicode code points beyond U+FFFF are represented by surrogate-pairs . The interesting thing is that Java and Windows and other systems that use UTF-16 all operate at the code unit level not the Unicode code point level . So the string consisting of the single character U+1D122 MUSICAL SYMBOL F CLEF gets encoded in Java as ud824 udd22 and ud824 udd22 .length 2 not 1 . So it s kind of a hack but it turns out that characters are not variable-length . The advantage of UTF-16 over UTF-8 is that one would give up too much if the same hack were used with UTF-8 . Comment : Me thinks yes me thinks : - that the world would be better if programmers had to know of variable-length characters instead of discovering them casually as it s now a programmer could live years without knowing that a code point could be long 2 if everything was UTF-8 he could keep the head under the earth only for some months : -", "Question : The unicode standard has enough code-points in it that you need 4 bytes to store them all . That s what the UTF-32 encoding does . Yet the UTF-8 encoding somehow squeezes these into much smaller spaces by using something called variable-width encoding . In fact it manages to represent the first 127 characters of US-ASCII in just one byte which looks exactly like real ASCII so you can interpret lots of ascii text as-if it were UTF-8 without doing anything to it . Neat trick . So how does it work I m going to ask and answer my own question here because I just did a bit of reading to figure it out and I thought it might save somebody else some time . Plus maybe somebody can correct me if I ve got some of it wrong . Comment : Straight Unicode does not require 32 bits to encode all its code points . They once did lay claim to that many possible code points but after UTF-8 took off they intentionally limited themselves to 21 bits so that UTF-8 will never exceed 4 bytes per character . Unicode currently requires only 17 bits to hold all possible code points . Without this limitation UTF-8 could have gone to 6 bytes per character . Comment : @Warren : mostly accurate but Unicode is a 21-bit code U+0000 to U+10FFFF . Comment : @Warren : 4-byte-limited UTF-8 could have supported up to U+1FFFFF . The restriction to U+10FFFF was made for the sake of UTF-16 . Comment : @dan04 Do we have any easy explanation of how it is restricted to U+10FFFF by UTF-16 It would be nice to know more about this . Comment : @A-letubby : Because the UTF-16 surrogate codes are allocated such that there are 1024 lead surrogates and 1024 trail surrogates and they can only be used in pairs to make 2 20 about a million additional characters available beyond the BMP . Added to the 2 16 characters available in the BMP this makes 0x110000 possible characters . .. . Answer : UTF-8 was another system for storing your string of Unicode code points those magic U+ numbers in memory using 8 bit bytes . In UTF-8 every code point from 0-127 is stored in a single byte . Only code points 128 and above are stored using 2 3 in fact up to 6 bytes . Excerpt from The Absolute Minimum Every Software Developer Absolutely Positively Must Know About Unicode and Character Sets No Excuses http : www.joelonsoftware.com articles Unicode.html Comment : That s a good article but it seems Joel is wrong regarding the maximum length of the sequence the Wikipedia page shows 1..4 bytes per character only . Comment : As I said above when UTF-8 was first created Unicode lay claim to up to 32-bits for code points not because they really needed it only because 32-bits is a convenient value and they d already blown past the previous limit of 16-bit characters . After UTF-8 proved popular they chose to forever limit the maximum number of code points to 2 21 that being the largest value you can encode with 4 bytes of the UTF-8 scheme . There are still less than 2 17 characters in Unicode so we can more than quadruple the number of characters in Unicode with this new scheme . Comment : Ok but not the explanation asked by OP . Comment : This is not answering the question . Comment : This does not provide an answer to the question . To critique or request clarification from an author leave a comment below their post . - From Review review low-quality-posts 10163216", "Question : I need to escape unicode characters within a input string to either UTF-16 or UTF-32 escape sequences .

I m tasked to escape unescaped input string-literals like Eat drink and store them to disk in their escaped literal form Eat drink u611b UTF-16 example If my program finds a UTF-32 character it should escape those too in the form U8902611b UTF-32 example but I can t find a certain way of knowing if I m dealing with UTF-16 or UTF-32 in an input byte array .

In what form are you storing the input Eat drink Your question seems as-if you re storing it as a byte array with unspecified encoding and you re attempting to guess what encoding it might be not for the whole array but for each individual character .

Comment : Note that Windows wchar-t is 2 bytes Linux wchar-t is 4 bytes . Windows wchar-t will take UTF-16 but not UTF-32 . Linux wchar-t will take both . If you just have a stream of bytes there is no way of differentiating unless there is a Byte Order Mark BOM character at the start of the sequence . Comment : Literals that contain any character beyond the basic source character set which is a subset of ASCII are implementation-dependent any method of dealing with them is non-portable . Whether your literals are UTF-16 UTF-32 UTF-8 or anything else is determined solely by your implementation and not by the content of the string . Comment : You can either require that requisite knowledge of the input format e.g . implied by platform or via a BOM or other means in order to produce a single transformed output or you can produce both possible outputs . In the absence of encoding knowledge there is no good way to distinguish UTF-16 bytes from UTF-32 bytes other than statistically . There is a statistics-based detector in the Windows API but it has made some quite infamous mis-identifications . .. . Answer : There are many questions within your question I will try to answer the most important ones . Q . I have a C++ string like Eat drink is it a UT8-8 UTF-16 or UTF-32 string .. . A . This is implementation-defined . In many implementations this will be a UTF-8 string but this is not mandated by the standard . Consult your documentation . Q . I have a wide C++ string like L Eat drink is it a UT8-8 UTF-16 or UTF-32 string .. . A . This is implementation-defined . In many implementations this will be a UTF-32 string . In some other implementations it will be a UTF-16 string . Neither is mandated by the standard . Consult your documentation . Q . How can I have portable UT8-8 UTF-16 or UTF-32 C++ string-literals .. . A . In C++11 there is a way : .. . .. . In C++03 no such luck . Q . Does the string Eat drink contain at least one UTF-32 character .. . A . There are no such things as UTF-32 and UTF-16 and UTF-8 characters . There are UTF-32 etc . strings . They all contain Unicode characters . Q . What the heck is a Unicode character .. . It is an element of a coded character set defined by the Unicode standard . In a C++ program it can be represented in various ways the most simple and straightforward one is with a single 32-bit integral value corresponding to the character s code point . I m ignoring composite characters here and equating character and code point unless stated otherwise for simplicity . Q . Given a Unicode character how can I escape it .. . A . Examine its value . If it s between 256 and 65535 print a 2-byte 4 hex digits escape sequence . If it s greater than 65535 print a 3-byte 6 hex digits escape sequence . Otherwise print it as you normally would . Q . Given a UTF-32 encoded string how can I decompose it to characters .. . A . Each element of the string which is called a code unit corresponds to a single character code point . Just take them one by one . Nothing special needs to be done . Q . Given a UTF-16 encoded string how can I decompose it to characters .. . A . Values code units outside of the 0xD800 to 0xDFFF range correspond to the Unicode characters with the same value . For each such value print either a normal character or a 2-byte 4 hex digits escape sequence . Values in the 0xD800 to 0xDFFF range are grouped in pairs each pair representing a single character code point in the U+10000 to U+10FFFF range . For such a pair print a 3-byte 6 hex digits escape sequence . To convert a pair v1 v2 to its character value use this formula : .. . .. . Note the first element of the pair must be in the range of 0xd800..0xdbff and the second one is in 0xdc00..0xdfff otherwise the pair is ill-formed . Q . Given a UTF-8 encoded string how can I decompose it to characters .. . A . The UTF-8 encoding is a bit more complicated than the UTF-16 one and I will not detail it here . There are many descriptions and sample implementations out there on the net look them up . Q . What s up with my L string .. . A . It is a composite character that is composed of four Unicode code points U+092A U+094D U+0930 U+0947 . Note it s not the same as a high code point being represented with a surrogate pair as detailed in the UTF-16 part of the answer . It s a case of character being not the same as code point . Escape each code point separately . At this level of abstraction you are dealing with code points not actual characters anyway . Characters come into play when you e.g . display them for the user or compute their position in a printed text but not when dealing with string encodings .

Some comments on it are wierd : It is possible in UTF-8 or any other multi-byte encoding to split or truncate a string in the middle of a character which may result in an invalid string . So a string that gets UTF-8 encoded is no more a string but a byte array or byte stream . The characters that make up the string get encoded . Of course it can be decoded as well . Now of course you can cut a utf-8 sequence after the start-byte or after a following byte but why should someone do this Comment : Short answer : Unicode is the standard for computers to display and manipulate text while UTF-8 is one of the many mapping methods for Unicode .. . Answer : To expand on the answers others have given : .. . .. . We ve got lots of languages with lots of characters that computers should ideally display . Unicode assigns each character a unique number or code point . Computers deal with such numbers as bytes.. . skipping a bit of history here and ignoring memory addressing issues 8-bit computers would treat an 8-bit byte as the largest numerical unit easily represented on the hardware 16-bit computers would expand that to two bytes and so forth . Old character encodings such as ASCII are from the pre- 8-bit era and try to cram the dominant language in computing at the time i.e . English into numbers ranging from 0 to 127 7 bits . With 26 letters in the alphabet both in capital and non-capital form numbers and punctuation signs that worked pretty well . ASCII got extended by an 8th bit for other non-English languages but the additional 128 numbers code points made available by this expansion would be mapped to different characters depending on the language being displayed . The ISO-8859 standards are the most common forms of this mapping ISO-8859-1 and ISO-8859-15 also known as ISO-Latin-1 latin1 and yes there are two different versions of the 8859 ISO standard as well . But that s not enough when you want to represent characters from more than one language so cramming all available characters into a single byte just won t work . There are essentially two different types of encodings : one expands the value range by adding more bits . Examples of these encodings would be UCS2 2 bytes 16 bits and UCS4 4 bytes 32 bits . They suffer from inherently the same problem as ASCII and ISO-8859 standars as their value range is still limited even if the limit is vastly higher . The other type of encoding uses a variable number of bytes per character and the most commonly known encodings for this are the UTF encodings . All UTF encodings work in roughly the same manner : you choose a unit size which for UTF-8 is 8 bits for UTF-16 is 16 bits and for UTF-32 is 32 bits . The standard then defines a few of these bits as flags : if they re set then the next unit in a sequence of units is to be considered part of the same character . If they re not set this unit represents one character fully . Thus the most common English characters only occupy one byte in UTF-8 two in UTF-16 4 in UTF-32 but other language characters can occupy six bytes or more . Multi-byte encodings I should say multi-unit after the above explanation have the advantage that they are relatively space-efficient but the downside that operations such as finding substrings comparisons etc . all have to decode the characters to unicode code points before such operations can be performed there are some shortcuts though . Both the UCS standards and the UTF standards encode the code points as defined in Unicode . In theory those encodings could be used to encode any number within the range the encoding supports - but of course these encodings were made to encode Unicode code points . And that s your relationship between them . Windows handles so-called Unicode strings as UTF-16 strings while most UNIXes default to UTF-8 these days . Communications protocols such as HTTP tend to work best with UTF-8 as the unit size in UTF-8 is the same as in ASCII and most such protocols were designed in the ASCII era . On the other hand UTF-16 gives the best average space processing performance when representing all living languages . The Unicode standard defines fewer code points than can be represented in 32 bits . Thus for all practical purposes UTF-32 and UCS4 became the same encoding as you re unlikely to have to deal with multi-unit characters in UTF-32 . Hope that fills in some details . Comment : Conceptually UCS-2 and UCS-4 are character sets not character encodings hence the name . Comment : There are lots of errors here . No code point occupies six bytes Comment : @tchrist : Would you point out those errors in more detail Comment : @Tuukka Errors in this posting are legion . There are more than just 2 versions of ISO 8859 . ASCII didn t work for English missing things like curly quotes cent signs accents a whole lot more Unicode is not just about non-English English needs it too No codepoints occupy more than 4 bytes in ANY encoding this 6-byte business is flat-out wrong . You can t UTF-encode any Unicode scalar value as this says : surrogates the 66 other noncharacters are all forbidden . UCS-4 and UTF-32 aren t the same . There is no multi-unit UTF-32 .

The C and C++ standards require wchar-t to be able to hold any valid character from all supported encodings . But there is no way to encode all of the Unicode characters in 16 bits -- it just can t be done . Therefore the Windows C and C++ libraries do not actually support Unicode of any kind . If you want to use Unicode on Windows you have to go outside the C and C++ libraries . Yes it s stupid but what did you expect from Microsoft : P Comment : @Let Me Be : You are confusing 16-bit wchar-t and UTF-16 . They are not the same thing . UTF-8 and UTF-16 are two different ways of encoding all of the Unicode code points of which there are far more than just 65535 . You need at least 24 bits to represent all 1 000 000+ Unicode code points . The 16 in UTF-16 does not mean that all characters representable using only 16 bits for instance some Unicode characters require 32 bits two 16-bit code units when encoded using UTF-16 . But the C++ library requires wchar-t to be able to uniquely represent every supported character . Comment : @Let Me Be : No conversion to wchar-t is not the same as conversion to UTF-16 . That s precisely what I m trying to explain although probably not as well as I d like . Some UTF-16 characters are going to need more than 16 bits to be able to represent them . wchar-t being only 16-bits on Windows can therefore not represent those characters . Again the C standard requires that wchar-t be able to uniquely represent every supported character . Comment : @Let Me Be : I did read your linked question but it seems that you didn t understand the correct answer there . Some or even all of the Windows APIs may interpret wchar-t strings as UTF-16 encoded data but the C and C++ libraries do not . If they did then you could use UTF-8 as a locale for the C and C++ libraries . But you can t . And that is the answer to your question here", "Question : Google App Engine uses Python 2.5.2 apparently with UCS4 enabled . But the GAE datastore uses UTF-8 internally . So if you store u ud834 udd0c length 2 to the datastore when you retrieve it you get U0001d10c length 1 . I m trying to count of the number of unicode characters in the string in a way that gives the same result before and after storing it . So I m trying to normalize the string from u ud834 udd0c to U0001d10c as soon as I receive it before calculating its length and putting it in the datastore . I know I can just encode it to UTF-8 and then decode again but is there a more straightforward efficient way Comment : Don t try to store u ud834 udd0c . Surrogates are not valid unicode code points so you shouldn t rely on them being preserved in strings or length working properly . Comment : To clarify : u blah in Python conceptually represents a sequence of Unicode code points . So you shouldn t put UTF-16 s binary representation into them . Comment : If you deleted the sentance about encoding and decoding from your question and added it as an answer I d probably upvote it because I think it s the most correct thing to do to get what you re asking for . .. . Answer : I know I can just encode it to UTF-8 and then decode again .. . .. . Yes that s the usual idiom to fix up the problem when you have UTF-16 surrogates in UCS-4 string input . But as Mechanical snail said this input is malformed and you should be fixing whatever produced it in preference . is there a more straightforward efficient way Well.. . you could do it manually with a regex like : .. . .. . Certainly not more straightforward.. . I also have my doubts as to whether it s actually more efficient Comment : Thanks . My input comes from a yaml stream that contained the surrogate code units and fixing the stream to not contain surrogates does seem to prevent them from showing up in the unicode . So I ll look into fixing the stream . Comment : What encoding s the YAML If it s UTF-16 those surrogates should be getting converted to single Unicode characters.. . if it s UTF-8 though then the producer has made a mistake . UTF-8-with-surrogates is known as CESU-8 and shouldn t be used . Comment : I m pretty certain the regex won t be more efficient . Comment : The yaml itself is a utf-8 encoded str but the unicode characters in the source data are represented with escape sequences in the yaml . This is with PyYAML on a python without UCS4 . So yaml.dump u U0001D10C produces this str : uD834 uDD0C len 14 . Comment : I agree . Filed pyyaml.org ticket 197 http : pyyaml.org ticket 197 .", "Question : The unicode standard has enough code-points in it that you need 4 bytes to store them all . That s what the UTF-32 encoding does . Yet the UTF-8 encoding somehow squeezes these into much smaller spaces by using something called variable-width encoding . In fact it manages to represent the first 127 characters of US-ASCII in just one byte which looks exactly like real ASCII so you can interpret lots of ascii text as-if it were UTF-8 without doing anything to it . Neat trick . So how does it work I m going to ask and answer my own question here because I just did a bit of reading to figure it out and I thought it might save somebody else some time . Plus maybe somebody can correct me if I ve got some of it wrong . Comment : Straight Unicode does not require 32 bits to encode all its code points . They once did lay claim to that many possible code points but after UTF-8 took off they intentionally limited themselves to 21 bits so that UTF-8 will never exceed 4 bytes per character . Unicode currently requires only 17 bits to hold all possible code points . Without this limitation UTF-8 could have gone to 6 bytes per character . Comment : @Warren : mostly accurate but Unicode is a 21-bit code U+0000 to U+10FFFF . Comment : @Warren : 4-byte-limited UTF-8 could have supported up to U+1FFFFF . The restriction to U+10FFFF was made for the sake of UTF-16 . Comment : @dan04 Do we have any easy explanation of how it is restricted to U+10FFFF by UTF-16 It would be nice to know more about this . Comment : @A-letubby : Because the UTF-16 surrogate codes are allocated such that there are 1024 lead surrogates and 1024 trail surrogates and they can only be used in pairs to make 2 20 about a million additional characters available beyond the BMP . Added to the 2 16 characters available in the BMP this makes 0x110000 possible characters . .. . Answer : RFC3629 - UTF-8 a transformation format of ISO 10646 http : tools.ietf.org html rfc3629 is the final authority here and has all the explanations . In short several bits in each byte of the UTF-8-encoded 1-to-4-byte sequence representing a single character are used to indicate whether it s a trailing byte a leading byte and if so how many bytes follow . The remaining bits contain the payload . Comment : Ummmm silly me I thought the Unicode Standard was the final authority on UTF-8 Comment : Unicode standard defines the Unicode itself . It doesn t define various methods today s and future that can be used to encode unicode texts for a variety of purposes such as storage and transport . UTF-8 is one of those methods and the above reference is to the document that defines it .", "Question : What are the differences between UTF-8 UTF-16 and UTF-32 I understand that they will all store Unicode and that each uses a different number of bytes to represent a character .

Unicode guys were smart when designing UTF-8 encoding . .. . Answer : In short : .. . .. . UTF8 : Variable-width encoding backwards compatible with ASCII . ASCII characters U+0000 to U+007F take 1 byte code points U+0080 to U+07FF take 2 bytes code points U+0800 to U+FFFF take 3 bytes code points U+10000 to U+10FFFF take 4 bytes . Good for English text not so good for Asian text . UTF16 : Variable-width encoding . Code points U+0000 to U+FFFF take 2 bytes code points U+10000 to U+10FFFF take 4 bytes . Bad for English text good for Asian text . UTF32 : Fixed-width encoding . All code points take 4 bytes . An enormous memory hog but fast to operate on . Rarely used .

UTF-8 is perfect for Japanese for example . I run a Japanese web site and everything is encoded in UTF8 and all works fine . UTF-8 can encode any Unicode character . Comment : @spurrymoses : I m referring strictly to the amount of space taken up by the data bytes . UTF-8 requires 3 bytes per Asian character while UTF-16 only requires 2 bytes per Asian character . This really isn t a major problem since computers have tons of memory these days compared to the average amount of text stored in a program s memory . Comment : UTF-32 isn t rarely used anymore.. . on osx and linux wchar-t defaults to 4 bytes . gcc has an option -fshort-wchar which reduces the size to 2 bytes but breaks the binary compatibility with std libs . Comment : @UstamanSangat Yes if this answer is restricted to only memory requirements then I missed the point . However that point was never made within the answer nor does the question require it . It appears then that I missed a point that was never made but that you somehow were able to see without it even being said . When someone says that UTF-8 is not so good for Asian text - without restricting it to the context of memory requirements then it is wrong . Comment : If someone were to say UTF-8 is not so good for Asian text in the context of All Encoding Formats Including Those That Cannot Encode Unicode they would of course be wrong . But that is not the context . The context of memory requirements comes from the fact that the question and answer is comparing UTF-8 UTF-16 and UTF-32 which will all encode Asian text but use differing amounts of memory storage . It follows that their relative goodness would naturally be entirely in the context of memory requirements . Not so good not good .", "Question : null .. .

So what happened in this process Comment : Java is open-source so if you wanted to you could just look at the code and see what it actually does . It s already on your filesystem Comment : I know but it would be easier to understand the source code if there are some advice from expert . Comment : The fact that strings are stored in UTF-16 by the JVM internally which by the way is not necessarily the case is somewhat irrelevant . From the language perspective a String is a String and does not have an encoding - you can convert between a String and a byte using the two methods you have used which are standard encoding decoding operations . What is your real question Comment : @assylias oh Your answer is very helpful . I thought String in java is encoded in UTF-16 . if it has no encoding then the conversion using getBytes make sense . One more question If String have no encoding is it represented in unicode which we call code point and what s the relationship between UTF-16 and String After all str in python have an encoding UTF-8 ascii etc .

May I recommend What Every Programmer Absolutely Positively Needs To Know About Encodings And Character Sets To Work With Text http : kunststube.net encoding not the same as linked to by @Avi .. . Answer : The pages you are using are confusing you somewhat . Neither your UTF-8 table or Unicode table are giving you the value of the code point in UTF-8 . They are both simply listing the Unicode value of the characters . In Unicode every character code point has a unique number assigned to it . The character is assigned the code point U+00F6 which is F6 in hexadecimal and 246 in decimal . UTF-8 is a representation http : www.cl.cam.ac.uk mgk25 unicode.html utf-8 of Unicode using a sequence of between one and four bytes per Unicode code point . The transformation from 32-bit Unicode code points to UTF-8 byte sequences is described in that article - it is pretty simple to do once you get used to it . Of course computers do it all the time but you can do it with a pencil and paper easily and in your head with a bit of practice . If you do that transformation you will see that U+00F6 transforms to the UTF-8 sequence C3 B6 or 1100 0011 1011 0110 in binary which is why that is the UTF-8 representation of . The other half of your question is about ISO-8859-1 . This is a character-encoding commonly called Latin-1 http : en.wikipedia.org wiki ISO IEC 8859-1 . The numeric values of the Latin-1 encoding are the same as the first 256 code points in Unicode thus is F6 in Latin-1 . Once you have converted between UTF-8 and standard Unicode code points UTF-32 it should be trivial to get the Latin-1 encoding . However not all UTF-8 sequences Unicode characters have corresponding Latin-1 characters .

BTW question marked as answered does not mean that the discussion should be over . The power of SO is that everything is here for prosperity.. . .. . Answer : Unicode defines among other things a bunch of code points and gives each one a numerical value . The value for HEBREW LETTER DALET is U+05D3 or 0x05D3 . But that s just a number and that DOES NOT tell you how to encode the code point i.e . the set of actual bits in a file in memory...UTF-8 as well as UTF-16 UTF-32 and a variety of other schemes tell you how to do that . There is actually a formulaic way of translating Unicode code points to UTF-8 characters but that s a whole different SO question . It turns out that in UTF-8 HEBREW LETTER DALET is encoded as 0xD7 0x93 . By the way if you find a text-editor that allows you to save-as UTF-32 or UCS-4 you will find that that in addition to a very large file the bytes that you see with a hex-editor should match the code points from the Unicode spec . This http : www.fileformat.info info unicode char 05d3 index.htm page may give a little extra information on some of the representations for that one character .

Comment : @pst : B e c a u s e i t l o o k s l i k e t h i s .. . Answer : If UTF-32 is available prefer that over the other versions for processing . If your platform supports UTF-32 UCS-4 Unicode natively - then the compressed versions UTF-8 and UTF-16 may be slower because they use varying numbers of bytes for each character character sequences which makes impossible to do a direct lookup in a string by index while UTF-32 uses 32-bit flat for each character speeding up some string operations a lot . Of course if you are programming in a very restricted environment like say embedded systems and can be certain there will be only ASCII or ISO 8859-x characters around ever then you can chose those charsets for efficiency and speed . But in general stick with the Unicode Transformation Formats . Comment : UTF-32 takes 4x the space of ASCII or UTF-8 when encoding ASCII characters for the same data . This can definitely matter . Plus unlike the legacy charsets like ISO-8859- and unlike UTF-8 you have byte-order endianness issues with UTF-32 and UTF-16 . Comment : UTF-32 or UCS-4 is a protocol for encoding Unicode characters that uses exactly 32 bits for each Unicode code point . All other Unicode transformation formats use variable-length encodings . The UTF-32 form of a character is a direct representation of its codepoint . http : en.wikipedia.org wiki UTF-32 UCS-4 Comment : @dkarp Just double checked and you re right . My bad Comment : @dkarp : that s why I wrote for processing in the first sentence . For storage you may want consider storage formats or compression depending on environment the speed of the components the frequency the strings are accessed and other factors . Optimisation is rarely done on one factor alone . -- But the primary factor is as I wrote the platform support . Windows for example used UTF-16 internally the last time I looked so going with UTF-16 will be best there leaving string operation optimisation to the platform library provider .

Answer : Going down your list : .. . .. . Unicode https : en.wikipedia.org wiki Unicode isn t an encoding although unfortunately a lot of documentation imprecisely uses it to refer to whichever Unicode encoding that particular system uses by default . On Windows and Java this often means UTF-16 in many other places it means UTF-8 . Properly Unicode refers to the abstract character set itself not to any particular encoding . UTF-16 http : en.wikipedia.org wiki UTF-16 : 2 bytes per code unit . This is the native format of strings in .NET and generally in Windows and Java . Values outside the Basic Multilingual Plane http : en.wikipedia.org wiki Basic Multilingual Plane BMP are encoded as surrogate-pairs . These are relatively rarely used - which is a good job as very few developers get them right I suspect . I very much doubt that I do . UTF-8 http : en.wikipedia.org wiki UTF-8 : Variable length encoding 1-4 bytes per code point . ASCII values are encoded as ASCII using 1 byte . UTF-7 http : en.wikipedia.org wiki UTF-7 : Usually used for mail encoding . Chances are if you think you need it and you re not doing mail you re wrong . That s just my experience of people posting in newsgroups etc - outside mail it s really not widely used at all . UTF-32 http : en.wikipedia.org wiki UTF-32 : Fixed width encoding using 4 bytes per code point . This isn t very efficient but makes life easier outside the BMP . I have a .NET Utf32String class as part of my MiscUtil http : pobox.com skeet csharp miscutil library should you ever want it . It s not been very thoroughly tested mind you .

They were based on drafts submitted for ANSI standardization but ANSI itself never standardized them . Windows-1252 the code page most commonly referred to as ANSI is similar to ISO 8859-1 Latin-1 except that Windows-1252 has printable characters in the range 0x80..0x9F where ISO 8859-1 has control-characters in that range .

Part of the problem is I don t know how to specify the code for use in strpos and I don t know if PHP has to be compiled with any special support for the code or if I have to use mb strpos which I am trying to avoid since it also might not be available . ie . for example the needle is U+56DE U+590D without the space .. . .. . With preg-match it might be preg-match @ x 56DE x 590D @ haystack but that actually requires @u which might not be available and I get a Compilation failed : character value in x .. . sequence is too large anyway . I don t want to use preg-match anyway as it might be significantly slower than strpos there are other sequences that have to be searched .

How do you specify unicode inline in PHP anyway I mean outside of PRCE .. . .. . blah u56DE u590D doesn t work .. . .. . Thanks for any ideas .. . Answer : First your question is poorly structured . It has several questions at several points . You would probably get more answers if you used a more clear structure : 1 describe the task you re trying to accomplish 2 the limitations requirements 3 the strategy you considered 4 the difficulties you found with such strategy is there a better one . That said I ll start by the end : .. . .. . blah u56DE u590D doesn t work No . The language doesn t know anything about unicode . In PHP strings are byte arrays . Therefore how you express a unicode code points in a PHP script depends on the encoding you want to use . For UTF-8 it would be xE5 x9B x9E xE5 xA4 x8D for UTF-16 big endian would be x56 xDE x59 x0D and so on . Can I convert U+56DE U+590D into its single byte sequence possibly 5-6 characters and then search for it via strpos I can t figure out how to convert it to bytes if so . For the first part yes i.e . converting U+56DE U+590D into bytes a clarification is needed . Are these UTF-16 code units or Unicode code points For instance how is represented U+D869 U+uDED6 or U+2A6D6 If they are unicode code units it s trivial to encode them into UTF-16 . For UTF-16 big endian it s just x56 xDE x59 x0D . Otherwise it s still trivial to encode them UTF-32 but it takes a little more work to do the same in UTF-16 or UTF-8 . For the second part keep reading . Part of the problem is I don t know how to specify the code for use in strpos and I don t know if PHP has to be compiled with any special support for the code or if I have to use mb strpos which I am trying to avoid since it also might not be available . What are you trying to do Why do you need to find a position in a string strpos will give you a byte offset for a given string again interpreted in binary form . Are you trying to clip a string strpos or even mb strpos mean trouble in Unicode a glyph can be constituted by several code units so you risk clipping part of a glyph . I can t advise you more unless you tell what you re trying to do . Comment : Many thanks for the detailed reply . Sorry about the unfocused question I should not have tried to ask it at 4am All I want to do is detect if the needle exists in the haystack I don t even need the position . I ll try to post the original unicode here at the end but really it s just an example of a general question I have about the rare but necessary need to search for unicode inside unknown strings . Please let me know how you create the conversion to bytes if it s not obvious . String follows : In html-entities it s 22238 22797 google helpfully converts it Comment : @ ck You can convert html-entites to your encoding of choice e.g . utf-8 with mb convert encoding string UTF-8 HTML-ENTITIES . If you want to see a byte representation you can do unpack H convString to the result-of that . Comment : @ ck As to your other question as long as the needle and the haystack are in UTF-8 it s safe to search for it in a binary manner with strpos . This is not true for UTF-16 or UTF-32 . You may want however to normalize both strings first . See php.net Normalizer http : www.php.net Normalizer and the links under See Also in that page . Comment : Thanks to your persistence and patience I figured out exactly what I really wanted how to convert the unicode directly into it s single byte representation so I could do a binary match instead of relying on mb functions in PHP . I made a little tool with input form and converted with this : unpack unpack H GET unicode echo x .implode str split unpack 1 2 x Which shows me your original six bytes : xe5 x9b x9e xe5 xa4 x8d but now I really understand how to get there with any unicode actually UTF-8 I think . Thanks again" ] }

But they depend on the application server implementation and the database you use . The filter in my opinion is more flexible and easier to implement .

Answer : Working from the answer to Jersey 2.3.1 on Google App Engine http : stackoverflow.com questions 19302237 jersey-2-3-1-on-google-app-engine and the accepted answer to Dependency injection with Jersey 2.0 http : stackoverflow.com questions 16216759 dependency-injection-with-jersey-2-0 17133081 17133081 I am trying to get Jersey 2.21 set up on Google App Engine . My configuration is similar to that shown in the above questions . I get the stack-trace shown below when starting the devserver . Searching around it is unclear to me whether anyone actually has the lastest version of Jersey working on App Engine . Am I just barking up the wrong tree here or should I be able to get it to work", "Question : I am coming from Node.js background and have quite a good understanding of RESTful web-services . Now I am trying to build RESTful web-services using Java . I understand core Java but completely new to Java based web development . I come to conclusion after some tutorials that I need to use Jersey framework to build my RESTful API . I understand that Jersey is some sort of reference implementation of JAX-RS . But I fail to understand relationship between various other terms and components like JAXB Jackson EclipseLink Moxy jersey-media-moxy Jettison JSON-P JSON XML etc . that come across my readings . The only thing that I could conclude was it is not so straight forward like JavaScript to covert Java objects into XML or JSON equivalent . My question is what is the relationship between these terms mentioned above and how they fit together if I am developing a Java based RESTful API . .. . Answer : There sure is a lot of terminology in the Java world and that can create a significant learning curve for new developers . It s not that it s particularly difficult to pass JSON or XML documents around using Java it s just that the various bits and pieces you need to do it have sprouted terminology over the years . I ve tried to list my understanding of the terms you ve used below.. . .. . .. . XML http : www.w3schools.com xml - you know what XML is right The extensible markup language . It s what we had before JSON became the big thing . JSON http : www.w3schools.com json - oh well JSON is the new big thing . It s a human-readable object serialisation format less verbose than XML . Very popular nowadays . It s the new magic bullet good for what ails ya gonna solve all your problems.. . .. . .. . JAXB https : jaxb.java.net - the Java Architecture for XML Binding in the Java ecosystem is the primary mechanism for turning XML data into objects which you can then interact with and vice versa . It s important to realise that it s an API and not an implementation so it mostly defines a set of annotations and simple classes interfaces in the javax.xml.bind package . To do anything useful with JAXB you need an implementation . There s a reference implementation included in the Glassfish application server . Most application servers will have some kind of implementation of JAXB . Jackson https : github.com FasterXML jackson - a library for data-binding . It supports both XML and JSON as document formats and implements the JAXB API . You can use Jackson as your implementation of JAXB or you can just use the Jackson API directly . EclipseLink Moxy https : wiki.eclipse.org EclipseLink FAQ MOXy - an alternative implementation of the JAXB API . Like Jackson it also has its own API . You can choose to use it or not . You probably don t want to use both Jackson and Moxy . Jersey-media-moxy - as you mentioned Jersey is an implementation of JAX-RS . One aspect of JAX-RS is passing documents around - often XML or JSON . To do that Jersey needs to know what underlying library to use for data-binding or stream processing . So jersey-media-moxy exists as a kind of jersey plugin dependency which you can use to configure Jersey to use Moxy for your object serialisation needs . There s an equivalent package for using jackson called jersey-media-json-jackson . Jettison https : github.com codehaus jettison - Yet Another serialisation library for converting Java objects to Json and back . JSON-P https : jsonp.java.net - an API for processing JSON either as a stream of events or via data-binding to an object . This API is still in development . You might ask how it is that anybody does json processing without it - the answer is that they either utilise proprietary library APIs such as Jackson or Moxy or they use a library which repurposes the JAXB API to work with JSON Jackson definitely allows this I m not sure about Moxy . JSON-P will make it easier to work directly with JSON features without all the XML-concepts which JAXB brings in .", "Question : Is there any sample code demonstrating how to use guice-servlet with Jersey 2.0 Comment : Any particular reason you want to use guice-servlet Jersey 2.0 is fully integrated with HK2 dependency-injection out of the box which as far as I have seen is very similar to Guice DI .

Comment : @joscarsson I have no desire to learn yet another DI framework . HK2 is not nearly as mature as Guice both from a functionality and community perspective . .. . Answer : For those interested there is a sample of guice jersey integration available at https : github.com mycom-int jersey-guice-aop . Comment : It s not clear what you re doing here especially because you talk about unidirectional injection but don t explain which direction you mean . You need a bi-directonal bridge because Jersey will always ask HK2 to inject in which can you want HK2 to delegate to Guice and on the flip side when you ask Guice to inject an Object which happens to contain a Jersey type e.g . UriInfo you need Guice to delegate to HK2 for injection . In short : a unidirectional bridge is not enough . Comment : Maybe to clarify : uni directional bridge is enough to inject Guice resources into Jersey . If you want to use AOP and mix Guice and HK2 then you definitely need the bi-directional bridge . Comment : You re going to have a very hard time not mixing Guice and HK2 . I ll give a specific example : if you inject a Jersey resource using Guice but it references UriInfo then Guice will need to delegate to HK2 to get an instance but won t be able to .", "Question : I am trying to create a custom http param binding for my restful service .

You are using Jersey 1.x flavored Jersey Test Framework but your app is Jersey 2.x . See below for 2.x dependency . I ve never used the Jersey 1.x flavored Test Framework but with Jersey 2.x the In-Memory container https : jersey.java.net documentation latest test-framework.html d0e16898 doesn t support servlet dependent features . See below for different dependency . With Jersey Test Framework you do not need to create the Client yourself . There is one created and we can simple call JerseyTest s target String path method to get back a WebTarget Jersey 2.x WebResource is Jersey 1.x .. . .. . Here is a refactor that works . Dependency I only added this dependency and didn t take anything out as your GitHub project didn t include anything test related as your code example above does .. . .. . Test .. . .. . For those not use an xml context file you can use an annotation config application context and add it as an init param .. . .. . Other Resources : .. . .. .

UPDATE .. . .. . So after a few more test here are a couple interesting things I discovered .. . .. . One : .. . .. . With the above dependency even if we don t configure the DeploymentContext and just override Application configure in the JerseyTest it will still work . Can t really explain it but it appears the descriptor is still picked up . Two : .. . .. . Even if we get rid of the above dependency grizzly and use the in-memory dependency the same simple previous test works . The documentation states .. . .. . In-Memory container is not a real container . It starts Jersey application and directly calls internal APIs to handle request created by client provided by test framework . There is no network communication involved . This containers does not support servlet and other container dependent features but it is a perfect choice for simple unit tests . So I am not completely sure what Servlet features they are referring to as this test still works .. . .. . What I don t understand in particular is this statement .. . .. . There is no network communication involved .. . .. . because when I run the test I see a log .. . .. . INFO : Creating InMemoryTestContainer configured at the base URI http : localhost : 9998 Comment : So I m trying to figure out where this overridden method is coming from DeploymentContext configureDeployment . I ve bumped several version of JerseyTest framework and cannot find where this method is coming from Comment : I would get rid of all the Jersey related dependencies that aren t org.glassfish.jersey . My Guess is you are still using the older JerseyTest which doesn t have that method . Comment : Well done sir . A very earnest thank you . Comment : And I will agree - this testing framework does some crazy magic behind the scenes", "Question : So I have a tomcat 8 + jersey 2.5.1 + weld CDI app that works very well in most cases . Where it fails is that I am unable to intercept jersey resource method calls with a CDI interceptor . This makes sense because a jersey resource class is not a CDI bean . Then is there any way to make a CDI interceptor work in jersey Another way to ask this question : Can a CDI bean be used as a Jersey resource Thanks EDIT : Before I wrote my RESTful resources using Jersey I had CDI interceptors that were used to begin and commit database transactions . I really need to follow the same or similar pattern to implement this cross-cutting transaction injection in my RESTful jersey resources . That is the main reason for asking this question . Thanks again Comment : YOu should be able to use a CDI bean as a Jersey resource in an EE container . In Tomcat servlet container it s a little more difficult since it s not built-in . Per this bug it should work : java.net jira browse JERSEY-883 https : java.net jira browse JERSEY-883 Comment : Thanks . That bug does say that CDI interceptors should work . Comment : I got rid of jersey in my app and replaced it with straight servlets . Now things work as they should and I dont have to deal with the ResourceConfig crud . Additionally I dont have to deal with java.net jira browse HK2-181 https : java.net jira browse HK2-181 and can use lambda expressions in my java8 code . Thanks to everyone who attended this question .. . Answer : Adam Bien in one presentation http : www.youtube.com watch v vvtuFLz2prk recommends that you separate your Service CDI or EJB class from your RESTful resources class . His reason was that the RESTful class usually uses the HttpHeaders injected by Jersey yet not available in the CDI or EJB containers . The hazard is that your RESTful classes could be injected a Null reference of HttpHeaders if any CDI client like the JSF framework uses it . Thanks to your self-answered question . You have just showed a second use-case that validates Adam Bien s recommendation . Simply keep them apart Comment : I m not sure how this answers the question . For example one use I have today is a CDI interceptor on certain REST APIs that checks for an active user login before activating the REST resource . Comment : Yeah even I am not sure how this answers the question .", "Question : I m trying to upgrade to Jersey 2.0 and I m having a lot of trouble because the groupIds and artifactIds of Jersey have completely changed and I can t find a migration plan in the Jersey docs https : jersey.java.net nonav documentation 2.0 index.html .

To achieve the workflow you have to first encode a video to Smooth Streaming format and then run it through the Encryptor task here http : msdn.microsoft.com en-us library hh973610.aspx with your PlayReady settings . Once you have an encrypted Smooth Streaming Asset you can then create a second HLS PlayReady protected asset by passing the file through the Packager task here http : msdn.microsoft.com en-us library hh973635.aspx . The resulting HLS Asset will be encrypted with PlayReady and the .m3u8 will contain the proprietary PlayReady tags for use by a player framework that is capable of getting a license and decrypting the content . There are several third party DRM companies that provide such player frameworks . Microsoft does not provide a PlayReady player SDK for iOS at this time so you have to go to a third party DRM company . Comment : Microsoft now have a client SDK for iOS http : www.microsoft.com playready features ClientOptions.aspx", "Question : Are there any tools available for adding Playready protection to MP4 content Thanks Comment : Be aware that simply encrypting the video won t help . You still need the PlayReady license server that delivers the content encryption key to the player . .. . Answer : You have to use Microsoft Expression Encoder to convert MP4 - WMV . Then you need to obtain PlayReady SDK and run the encryptor to encrypt the WMV file . This will given you what you need . If you need to protect the content in order to share via adaptive streaming use a Transformation Manager IIS extension . Comment : This is not correct . You don t have to convert it to WMV . The expression-encoder can create .ismv files which are playready protected mp4 files . Comment : This is not correct either . ISMV are not playready protected - these are just files for smooth streaming . You ll need to run IIS Transform Manager job to make them PlayReady protected . Comment : You are right . My wording is wrong here - it should be : The expression can create encrypted playready protected .ismv files . These files are suitable for download protected file -use-case . And yes : You can also put the files on an IIS together with ismc and ism file to stream them . BTW . : my downvote was too harsh .", "Question : I wonder whether anyone has tried using NdkMediaDrm with PlayReady If so is there any documentation available .. . Answer : The NdkMediaDrm API is designed for interacting with DRM technologies built into the Android operating-system by the device s manufacturer . While there are Android devices that do include PlayReady e.g . most Samsung devices I lack information on whether they expose PlayReady through this API . If you are simply looking to enable PlayReady playback on Android you will want to use the Microsoft PlayReady Client SDK for Android http : www.microsoft.com playready features ClientOptions.aspx . Comment : Thanks I hadn t realised it wasn t a standard thing .

The free trial includes access to a PlayReady and Windows Media DRM license server and all the licensing related functionality that goes along with that .

Alternatively Microsoft has a public PlayReady test server http : playready.directtaps.net pr doc customrights that you can use for free .

After I read the PlayReady documentation I found out that I also need to implement some code in my app but it doesn t mention for which server I stream or something else.Just how to implement their SDK . My app functionality is similar to GoCoders . It streams the media using an rtsp connection and the video is a H.264 format . My question is what is the proper way to implement the PlayReady SDK and make it work with my app and the wowza servers I mean crypting securing my videos Thank you .. . .. . Bob .. . .. . P.S . My app is not public yet . .. . Answer : Bob - DRM can be pretty complex and in most cases suited best suited for high value content if you want to do that route there is some lifting to do . The article you noted above tells you how to set up the BuyDRM PlayReady module on Wowza Streaming Engine with any incoming source not just GoCoder . Once you have enabled PlayReady on the Wowza server you will not need to do anything more in the app as far as encoding goes the encryption is all done on the server . What you will need however is a custom player that can play back this encrypted stream as well as a PlayReady key server to manage access . You may want to consider a somewhat lighter solution like secure token and streamlock which is focused more on preventing unauthorized playback and transport encryption rather than content encryption .", "Question : I am trying to do an experiment with encrypted Microsoft smooth streaming streams .

I have found a few sources that specify the definition of the P160 curve since it is non-standard and custom . Below is a link-to one source . In particular the PlayReady curve values are discussed in Section 6.4.2 http : www.scribd.com doc 55582525 45 Elliptic-Curve-Cryptography of the book Elementary Number Theory A Computational Approach by William Stein . Below is an exert from another source http : cryptome.org ms-drm.htm concerning the P160 PlayReady curve parameters . For ECC Microsoft is using an elliptic-curve over Zp where p is a 160 bit prime number given below . The curve consists of the points that lie on the curve y 2 x 3+ax+b where the operations are done over the field Zp and a and b are coefficients that are given below . All values are represented as packed binary values : in other words a single value over Zp is encoded simply as 20 bytes stored in little endian order . A point on the elliptic-curve is therefore a 40 byte block which consists of two 20 byte little endian values the x coordinate followed by the y coordinate . Here are the parameters for the elliptic-curve used in MS-DRM : .. . .. . p modulus : 89abcdef012345672718281831415926141424f7 .. . coefficient a : 37a5abccd277bce87632ff3d4780c009ebe41497 .. . coefficient b : 0dd8dabf725e2f3228e85f1ad78fdedf9328239e .. . generator x : 8723947fd6a3a1e53510c07dba38daf0109fa120 .. . generator y : 445744911075522d8c3c5856d4ed7acda379936f .. . Order of curve : 89abcdef012345672716b26eec14904428c2a675 .. . .. . These constants are fixed and used by all parties in the MS-DRM system . The nerd appeal of the modulus is high when you see this number in hexadecimal : it includes counting in the hexadecimal as well as the digits of fundamental constants e pi and sqrt 2 . Based on this information I have created the following hex-encoding of the DER encoded curve parameters for the P160 curve using BouncyCastle as my base ASN.1 library . Note that no seed value is specified in these curve parameters . 308195020101302006072a8648ce3d010102150089abcdef012345672718281831415926141424f7302c041437a5abccd277bce87632ff3d4780c009ebe4149704140dd8dabf725e2f3228e85f1ad78fdedf9328239e0429048723947fd6a3a1e53510c07dba38daf0109fa120445744911075522d8c3c5856d4ed7acda379936f02150089abcdef012345672716b26eec14904428c2a675 .. . .. . Although mathematically these curve parameters are accepted by the HSM and OpenSSL the P160 curve points produced are not acceptable to PlayReady . I am able to use the same process to produce valid P256 curve points that are acceptable to PlayReady so I do no believe my methods are flawed . Does anyone have any experience with the PlayReady P160 curve parameters .. . Answer : After researching with Microsoft the solution was found . Apparently one must byte swap the public-key x y points and the private key to get the PlayReady tool kit to accept the EC key pair only for the P160 curve . This odd byte swapping was not required for the P256 EC key pair . Comment : That answer swapping public and private key does not make any sense to me hopefully it does make sense to others .", "Question : Second bind call failed with license expire for Non persistence license in Play ready .. . .. .

Actually I am in 2nd year of college and starting an internship . They want me to do a program in C++ builder but I only know C . What I studied . And I don t have any knowledge about OOP . So my question is . I have TEdit1 and I want to verify if the data introduced in that textbox is a number . I know to verify if it is a number but I don t know how to put data from TEdit into string . I wrote some code but it doesn t work . And I get these errors : .. . .. . Can you please explain what i did wrong or where i can found Embarcadero C++ Builder tutorials I searched all google and didn t find something to help me . .. . Answer : Your code has several mistakes in it : .. . .. . 1 . you are declaring two Buffer variables in the same scope . That is not allowed . You need to remove one of them . 2 . you are passing the std : : auto-ptr http : en.cppreference.com w cpp memory auto-ptr itself to ShowMessage but it expects a System : : UnicodeString http : docwiki.embarcadero.com Libraries XE7 en System.UnicodeString instead thus the compiler error message . You can use the std : : auto-ptr : : get method to get the wchar-t pointer and pass it to ShowMessage as UnicodeString has a constructor that accepts wchar-t as input : .. . .. . ShowMessage Buffer.get .. . .. . .. . 3 . despite the above you actually cannot use a pointer from new with std : : auto-ptr to begin with . std : : auto-ptr uses delete instead of delete to free the memory being pointed at . You must always use delete with new and delete with new . So while the code will compile it will not free the memory correctly at runtime . C++11 introduced a new std : : unique-ptr http : en.cppreference.com w cpp memory unique-ptr class to replace std : : auto-ptr and std : : unique-ptr supports new and delete however C++Builder s 32bit compiler does not support C++11 yet - that is in the works - but its 64bit compiler does : .. . .. . include memory .. . .. . void fastcall TForm1 : : Button1Click TObject Sender .. . .. . int Size Edit1- GetTextLen Get length of string in Edit1 .. .

Edit1- GetTextBuf Buffer.get Size Puts Edit1- Text into Buffer .. . .. . ShowMessage Buffer.get .. . .. . .. . .. . Now with that said if you are going to continue using C++Builder you should learn how to use its built-in functionalities like UnicodeString which the RTL VCL relies heavily on use the System : : String alias for most code use UnicodeString directly only when absolutely necessary . Your example can be vastly simplified using the TEdit : : Text http : docwiki.embarcadero.com Libraries XE7 en Vcl.StdCtrls.TEdit.Text property : .. . .. .

But if you have to stick with TEdit there are many ways to check a UnicodeString for numeric content . You can set the TEdit : : NumbersOnly http : docwiki.embarcadero.com Libraries XE7 en Vcl.StdCtrls.TEdit.NumbersOnly property to true so the user cannot enter a non-numeric value unless they use copy-paste but let s ignore that for the moment and then use the RTL s StrToInt http : docwiki.embarcadero.com Libraries XE7 en System.SysUtils.StrToInt function or System : : UnicodeString : : ToInt http : docwiki.embarcadero.com Libraries XE7 en System.UnicodeString.ToInt method to convert it as-is : .. . .. .

To use it rename your ilink32.exe in your RAD Studio binaries directory e.g . C : Program Files x86 Embarcadero Studio 17.0 bin for RAD Studio Seattle and copy mine in its place . I am using RAD Studio 10 Seattle Update 1 on Windows 10 . This problem has been around for a long time and is not limited to XE3 XE5 XE7 XE8.. . There is now a lengthy discussion lament as to why this was fixed in one version of RAD Studio but backed out in a later version apparently LAA resulted in failures when linking incrementally with the static RTL . See : https : quality.embarcadero.com browse RSP-13247 .. . .. . Also in the above link posted 28-Mar-2016 : apparently this patch does NOT address the linker errors EXE1825 or out-of-memory . Read below if you want to see how my ilink32.exe was created.. . .. . .. . .. . .. . 1 . Copy bcc32.exe and ilink32.exe to prevent UAC s block and to back them up .. . .. . D : copy C : Program Files x86 Embarcadero RAD Studio 12.0 bin bcc32.exe . .. . .. . D : copy C : Program Files x86 Embarcadero RAD Studio 12.0 bin ilink32.exe . .. . .. . 2 . Set Large Address Aware flag in their PE header with editbin.exe tool included in MS Visual Studio but see below : .. . .. . D : editbin LARGEADDRESSAWARE bcc32.exe .. . .. . D : editbin LARGEADDRESSAWARE ilink32.exe .. . .. . 3 . Overwrite them on the original locations . Explorer will make this operation easier to force UAC to allow us copying them . For those of you reluctant to install MS Visual Studio just to run editbin which MS claims must be run from within the IDE there is a simpler standalone installation : http : www.masm32.com download.htm which creates c : masm32 bin editbin.exe . I got a few warnings involving ordinals 201 and 203 during MASM32 installation but its self-test passed and all I needed was editbin.exe . Comment : In your case were you actually running into large file problems Some of the other people having LME288 only had small projects and the error did seem to be caused by corrupted or badly-permissioned temporary file so perhaps the same error-code is used for two quite separate problems .

Even the incremental link began to work again Comment : Thanks for sharing This also worked for me with C++ Builder XE6 . For anyone else with this issue Disk Cleanup is the Windows tool cleanmgr.exe and not a feature of C++ Builder . Comment : I wonder if it could be related to temporary files being owned by Administrator and you are running C++B as user and so it cannot write the required temporary files Comment : Sometimes it helps sometimes not . I wish I could withdraw my upvote . Comment : I ve tried this before and it appeared to work but today I spent 3 hours trying everything that I could think of with no luck . I lost the count on how many times I run the Disk Clenaup restarted cleaned by hand all temps ran as Administrator and so on .

Answer : I have a different solution that hopefully will help someone struggling with this . I tried everything and none of the solutions suggested earlier worked for me . Disk cleanup didn t help . This is clearly a bug in C++Builder that existed for many years and is still not fixed even in XE8 as of 2015 .

Comment : virtual doesn t help but I found out that if I declare the ShowModal body in the class definition it works but not If I place it in the .cpp file .

I can find stuff for HTTPS and SMTP but nothing for custom connections . In BCB5 it was a lot easier I would do it with custom code but now with Android and iOS things need to be done a little differently as we now need to support these products too . I ve looked at TIdSocketSSL but with the very few examples I could find it seems to need an owner which ultimate comes from SMTP or HTTPS . .. . Answer : C++Builder ships with Indy which has a TIdTCPClient component that you can use for implementing custom protocols . There are plenty of examples on Embarcadero s forum Indy s forum StackOverflow and various blogs demonstrating how to send receive custom data with Indy . For SSL TLS simply assign a TIdSSLIOHandlerSocketOpenSSL component to the TIdTCPClient : : IOHandler property before calling Connect and configure its properties as needed certificates SSL TLS version s etc . When you want to perform the SSL handshake set the TIdSSLIOHandlerOpenSSL : : PassThrough property to false . You can set it before calling Connect so the handshake is immediate before any data is exchanged aka implicit SSL TLS or you can set it after exchanging unencrypted data first aka explicit SSL TLS depending on your protocol needs .", "Question : I am trying to use the code below to open an .xlsx file from C++Builder in RAD Studio XE7 : .. . .. .

Seems like something with static-cast conversion on the screen doesn t it Comment : The cast is working fine I think . Comment : What happens when you change the filename to something other that 1 Comment : Error remains the same when I change the path to D : file.xlsx .. . Answer : The problem seems very specifically related to the use of C++ and thus the way that C++ compilers deal with literal strings or at least this particular C++ compiler . Quite what the problem is in this case I cannot say - it could even be a bug in the compiler since seemingly correct escaping doesn t address the problem . You could employ various strategies to eliminate the possibility that it is handling of the literal string in this case . But since this does involve a literal string and since you are using XE7 I believe you should be able to bypass this more explicitly by expressing the literal as a raw string as per C++11 which is should be supported by C++ Builder XE7 : .. . .. . Note that with raw string-literals you specifically do not escape chars . Comment : I have tried it with no success Comment : @Deltics It is a stretch to imagine that there exists a compiler that cannot escape backslashes in literals . Comment : Possibly but if the problem was in the OLE objects the file system or the OLE automation server then you would see the same result no matter what language was involved . It s too much of a coincidence that the problem only arises when one particular language is being used . And this is an Embarcadero compiler we re talking about... . a vendor not known for the quality of their work . Certainly not lately . Try the same C C++ code in Visual Studio and see what happens First eliminate the impossible.. . Comment : @Deltics Escapes in literals work in all compilers . It s the COM dispatch that is unique to Emba . I can t imagine how they stuffed it up . Comment : Ah yes didn t spot the OleProcedure intermediate . As I said.. . Not a vendor known for the quality of their work.. .", "Question : I have RAD Studio XE7 installed on my computer and i have everything like VCL Forms for Delphi C++.etc but how do i manage to get FireMonkey HD and 3D application frameworks for Delphi and C++ Builder both in RAD Studio XE7.Do I have to download it or it is already in RAD Studio XE7 and I have to follow some steps to get FireMonkey . .. . Answer : FireMonkey is pre-installed as part of the IDE . You do not need to do anything extra to get it . In earlier versions there were separate FireMonkey Desktop Application which had HD and 3D options and FireMonkey Mobile Application projects . They no longer exist as separate projects in XE7 .

What else can I do to fix this EDIT .. . I tried to rebuild a couple of other projects that has been running fine for years and now I get the LME288 error on all my projects . Comment : This has been reported to QualityCentral several times over the years : 102099 http : qc.embarcadero.com wc qcmain.aspx d 102099 106085 http : qc.embarcadero.com wc qcmain.aspx d 106085 and 109265 http : qc.embarcadero.com wc qcmain.aspx d 109265 Comment : All three reports are closed without any solution or workaround . I doubt this problem is project related . One guy had even reinstalled Builder and still had the problem . It must be some cached files being corrupted . I m cleaning up all my temp folders to see if it helps . Comment : I cleaned the disk from all temporary files emptied the trashbin and now it works again . Comment : @MaxKielland a similar fix is suggested in the last comment to QC 102099 http : qc.embarcadero.com wc qcmain.aspx d 102099 . Would be nice if this was enough of a clue for QC to try and fix the problem Comment : This bug in builder makes me seethe . I have had a huge exchange with Embarcadero support trying to get to the bottom of it . All my problems started with XE7 on Windows 10 along the way several things fixed it for me for a short time . Installing XE8 fixed XE7 . Cleaning up my project by removing non-version controlled files . However the one thing that has given me the biggest fix fine for a few months until today was making a new user account on my PC . Now I am sitting here raging at the time I m wasting I will never ever use Builder again by choice because of this bug . .. . Answer : I have been having this problem as well with RAD Studio XE8 installed on Windows 10 . When installed on Windows 7 x86 RAD Studio XE8 worked properly . After upgrading to Windows 10 x86 I ran into the dreaded unknown heap LME288 errors . At first it didn t appear on Windows 10 but if I installed something it would pop-up . If I restored the computer to Windows 7 it would disappear . After a little research on the net I found the solution . There is a memory problem with ilink32.exe and you need to enable the 3GB memory space at bootup on the computer . Here is what I do now if this error is ever displayed again : .. . .. . 1 . Run command-prompt as Administrator . 2 . Type without quotes bcdedit set IncreaseUserVa 3072 .. . 3 . Reboot computer . After doing that ilink32 works properly . I found that after installing a newer version of Acronis True Image 2016 the LME288 error came back . But running the bcdedit solution here it fixed the RAD Studio XE8 linker Comment : this solution works Comment : ilink32.exe is not compiled with LARGEADDRESSAWARE flag . So I dont understand how this solution could work . Comment : For me this solutions doesnt work . Comment : works for me thanks Comment : Worked for me as well" ] }

Extended the FileAppender and used it in the config file . 2 . Inside the setFile method I appended process name and id to the file name you can do it in the setOption method if you don t use a rolling file . We already had a mechanism for uniquely identifying our processes and their instances by our internal id you could use a PID for example or add a global variable and set it in every application using log4cxx to your unique value then using it in the setOption method of your appender .

Then .. . .. . 1 . manually extract this zip apr-1.2.11-win32-src.zip the extracted folder should be named apr if it is not manually rename it .. . 2 . manually extract this zip apr-util-1.2.10-win32-src.zip the extracted folder should be named apr-util if it is not manually rename it .. . 3 . open a command-prompt and run the following : cd apache-log4cxx-0.10.0 configure this will execute configure.bat .. . .. . We will need to disable to use of the APR ICONV and LDAP support . In order to do so we will append the following files manually : .. . .. . 1 . Open apr-util include apu.hw . Find the line starting with define APU HAVE APR ICONV . Change the value to 0 and save . 2 . Open apr-util include apr ldap.hw . Find the line starting with define APR HAS LDAP Change the value to 0 and save . .. . We need to build the log4cxx.dll to do so convert .dsw to .cxproj . .. . 1 . Launch Visual Studio 2013 and open log4cxx.dsw . 2 . VS will ask if you like to convert everything . Simply click Yes . There may be some warnings in the migration report but nothing that should prevent the solution from opening . .. . The projects xml apr and apr-util should build successfully . .. . .. . If you try compiling the log4cxx project it will most likely fail with hundreds of errors . This is due to a bug in VC++ which can be worked around . .. . 1 . Move all macros outside above the class they are in . LOG4CXX LIST DEF macro is used to define classes . All macros reported in error C2252 will need to move out of any classes . This may also include moving definitions which are used in the macro . 2 . Next change all LoggingEvent : : KeySet to KeySet this is no longer nested in a parent class .. . .. .

This blog post shows one way to go about it : http : blackbeanbag.net wp 2009 01 14 log-file-management-in-coherence-using-log4j .. . .. . Basically pass in the process id as a system property and then use that in the Log4j pattern . Apparently this is due to the JVM not providing an easy method to access the process id .

Can i do the same for the log4cxx from config file If yes how .. . Answer : According to the log4cxx documentation in order to currently do this you need to declare at least one MappedDiagnostic context . An untested partial snippet of doing so is shown below .. . .. . After further inspection of the log4cxx source I realised that file doesn t take a ConversionPattern but FileNamePattern does . I believe you can only use FileNamePattern when you have use a TimeBasedRollingPolicy or FixedWindowRollingPolicy . Now you can add the processid to the log by adding the following parameter in your appender tags in the XML configuration file . or you can include it in the pattern layout by specifying the following layout tags also inside your appender tags in the XML configuration file . There is no simple way from the configuration file only to have each process append its own process to its own log like you are familiar with in log4net .

Answer : I d recommend Pantheios http : www.pantheios.org . It takes some time to build everything when you first download - type make build test and go have lunch - and you have to select the output streams Pantheios calls them back ends at link time but for coding it is really simple e.g . It s designed from the ground up for speed - the age won t be converted into a string unless the DEBUG level is switched on - and robustness - which is why you can t pass fundamental types directly and use inserters e.g . pantheios : : integer .

I have fixed it with your first post : One more thing how to find anchor tags which have no img tag as child element Instead of src and alt I need anchor text Comment : First guess : query a not img to get non-image links and query text from there to get each text node within those links .

My xml is as below .. . .. . My question is do I have to define the Java object that this will be converted into What I am afraid of if this is the case is what happens if data is added or removed from the XML response as it exists at the moment .

But it might be simpler to use the system-properties method .. . at least until you can figure out what is going wrong with the services method . Comment : The services mechanism is about components which provide a service announcing that they do so . It s about providing a choice . It is not about specifying which choice to make and relying on classpath ordering to use it to do that seems like a kludge to me . The system-properties method is a way of making an explicit choice and so it is the right way to do this here . Comment : @Tom Anderson - in defence of the OP my reading of the linked document is that the services approach ought to work . And I found other search hits that suggest this is true for OAS as well . However I must admit that the way the document is phrased leaves some room for doubt and I couldn t find OAS specific documentation . Comment : yes you re quite right . The services approach really ought to work everywhere since it s part of the JRE . I merely think it s better to be explicit ." ] }
