I want to get the HTML content of a web page but most of the content is generated by javascript. Is it posible to get this generated HTML (with python if posible)?

The only way I know of to do this from your server is to run the page in an actual browser engine that will parse the HTML, build the normal DOM environment, run the javascript in the page and then reach into that DOM engine and get the innerHTML from the body tag. This could be done by firing up Chrome with the appropriate URL from Python and then using a Chrome plugin to fetch the dynamically generated HTML after the page was done initializing itself and communicate back to your Python.

If most of the content is generated by Javascript then the Javascript may be doing ajax calls to retrieve the content. You may be able to call those server side scripts from your Python app. Do check that it doesn't violate the website's terms though and get permission.

So I have tried to find a answer but must not be searching correctly or what I'm trying to do is the wrong way to go about it. So I have a simple python script that creates a chess board and pieces in a command line environment. You can in put commands to move the pieces. So one of my co workers thought it would be cool to play each other over the network. I agreed and tried by creating a text file to read and write to on the network share. Then we would both run the script that reads that file. The problem I ran into is I pretty much DOS attacked that file share since it kept trying to check that file on network share for a update. I am still new to python and haven't ever wrote code that travels the internet, our even a simple local network. So my question is how should I go about properly allowing 2 people to access this data at the same time with out stealing all the network resources? Oh also im using version 2.6 because thats what everyone else uses and they refuse to change to new syntax

false

9,629,040

First off, without knowing how many times you are checking the fle with the moves, it is difficult to know why the file-share is getting DoS-ed. Most networks and network shares these days can handle that level of traffic - they are all gigabit Ethernet, so unless you are transferring large chunks of data each time, you should be ok. If you are transferring the whole file each time, then I'd suggest that you look at optimizing that. That said, coming to your second question on how this is handled at a network level, to be honest, you are already doing it in a certain way - you are accessing a file on a network share and modifying it. The only optimization required is to be able to do it efficiently. Even over the network operations in a concurrent world do the same. In that case, it will be using fast in-memory database storing various changes / using a high-scale RDBMS / in the case of fast-serving web-servers better async I/O. In the current case, since there are two users playing the game, I suggest that you work on a way to transmit only the difference in the moves each time over the network. So, instead of modifying the file over the network share, you can send the moves over to a server component and it synchronizing the changes locally to the file. Of course, this means you will need to create a server component that would do something like this user1's moves <--> server <--> user2's moves . Server will modify the moves file. Once you start doing this, you get into the realm of server programming / preventing race conditions etc. It will be a good learning experience.

I'm a newer and if the question is so easy I apologize for that. Assume I want to dev a classical online judge system, obviously the core part is get users' code to a file compile it on server run it on server (with some sandbox things to prevent damage) the program exit itself, then check the answer. or get the signal of program collapsing. I wonder if it's possible to do all the things using Node.js, how to do the sandbox things. Is there any example for compile-sandbox-run-abort-check thing? additional: is it more convenient to dev a such system using PYTHON? thanks in advance.

To accomplish the sandbox, it would be fairly easy to do this by simply running your code inside of a closure that reassigns all of the worrisome calls to NaN for instance, if the code executes inside a closure where eval=NaN

Put your Python script in your CGI directory and use the cgi and json modules in your script to read AJAX from post/get params. Of course you can do a system call from PHP to run a Python script, but I can't think of a good reason why you would.

I am working on a Python script that will extract data from Database and prepare data for a front graph amCharts tool. I am returning data via an AJAX call made from the front end side in JSON / XML format. Is it safe to return data in JSON / XML format to browser - in case if my tool goes to live wouldn’t the JSON / XML format would be viewable to client side before reading. Is it a safe way for data to be transmitted to client side? What are the other ways the Python script can print out data such that client side can show data in graphs etc in secured way? Also is my approach correct - is there any other way to represent data as Graphs? Please advice

You should use HTTPS on your server, so that the data is encrypted as it leaves the server. Ultimately, though, the browser will decrypt the data. If at anytime you don't even want the target end-user to see the data, then you have to follow this rule: don't send it.

In my main program, I do from bots.google import GoogleBot and I've looked at how to use reload to reload modules, but I still can't figure out how to do dynamic re-importing of classes.

Id like to know if there is a way to get information from my banking website with Python, Id like to retrieve my card history and display it, and possibly save it into a text document each month. I have found the urls ext to login and get the information from the website, which works from a browser, but I have been using liburl2 to "open" the webpages from Python and I have a feeling its not working because of some cookie or session things. I can get any information I want from a website that does not require a login with urllib2, and then save the actual HTML and go through it later, but I cant on my banks website, Any help would be appreciated

This is a part of Web-Scraping : Web-scraping is a standard task that can serve various needs. Scraping data out of secure-website means https Handling https is not a problem with mechanize and BeautifulSoup Although urllib2 with HTTPCookieJar also works fine If managing the cookies is the problem, then I would recommend mechanize Considering the case of your BANK-Site : I would recommend not to play with your account. If you must then, its not as easy as any normal secure/non-secure site. These sites are designed to with-stand such scripts. Problems that you would face with this: BANK sites will surely have Captcha that is almost impossible to by-pass with a script unless you employee a lot of rocket-science and effort. Other problem that you will definitely face is javascript, standard scripting solutions are focused to manage cookies, HTML parsing, etc. For processing javascript on links you will have to process js in your python script. That again needs a lot of effort. Then, AJAX that again comes from javascript fetches data from server after page-load. So, it will require you to take a lot of effort to do this task. Also, if you try doing this you risk of blocking access to your account since banking sites are quick to block account access on 3-4 unsuccessful attempt on login or captcha, etc. So, think before you do.

I wonder if TDD could help my programming. However, I cannot use it simply as most of my functions take large network objects (many nodes and links) and do operations on them. Or I even read SQL tables. Most of them time it's not really the logic that breaks (i.e. not semantic bugs), but rather some functions calls after refactoring :) Do you think I can use TDD with such kind of data? What do you suggest for that? (mock frameworks etc?) Would I somehow take real data, process it with a function, validate the output, save input/output states to some kind of mock object, and then write a test on it? I mean just in case I cannot provide hand made input data. I haven't started TDD yet, so references are welcome :)

You've pretty much got it. Database testing is done by starting with a clean, up-to-date schema and adding a small amount of known, fixed data into the database. You can then do operations on this controlled environment, knowing what results you expect to see. Working with network objects is a bit more complex, but it normally involves stubbing them (i.e. removing the inner functionality entirely) or mocking them so that a fixed set of known data is returned. There is always a way to test your code. If it's proving difficult, it's normally the code design that needs some rethinking. I don't know any Python specific TDD resources, but a great resource on TDD in general is "Test Driven Development: A Practical Guide" by Coad. It uses Java as the language, but the principles are the same.

I've just created a web chat server with Tornado over Python. The communication mechanism is to use long-polling and I/O events. I want to benchmark this web chat server at large scale, meaning I want to test this chat server (Tornado based) to see how many chatters it can withstand. Because I'm using cookies to identify sessions, presently I can only test with maximum 5 (IE, Firefox, Chrome, Safari, Opera) sessions per computer (cookie path has no use coz everything goes thru' the same web page), but in my office we only have limited number of computers. I want to test this Tornado app at the extreme, hopefully it can withstand few thousand concurrent users like Tornado is advertising, but having no clue how to do this!

I would run the server in a mode where you let the client tell which client they are. i.e. change the code so it can be run this way as required. This is less secure, but makes testing easier. In production, don't use this option. This will give you a realistic test from a small number of client machines.

I'm trying to create a 'Download Manager' for Linux that lets me download one single file using multiple threads. This is what I'm trying to do : Divide the file to be downloaded into different parts by specifying an offset Download the different parts into a temporary location Merge them into a single file. Steps 2 and 3 are solvable, and it is at Step #1 that I'm stuck. How do I specify an offset while downloading a file? Using something along the lines of open("/path/to/file", "wb").write(urllib2.urlopen(url).read()) does not let me specify a starting point to read from. Is there any alternative to this?

first, the http server should return Content-Length header. this is usually means the file is a static file, if it is a dynamic file, such as a result of php or jsp, you can not do such split. then, you can use http Range header when request, this header tell the server which part of file should return. see python doc for how set and parse http head. to do this, if the part size is 100k, you first request with Range: 0-1000000 100k will get first part, and in its conent-length in response tell your the size of file, then start some thread with different Range, it will work

Is it possible to upload a video on youtube with a remote URL (not from the local machine). I am using Youtube API and python gdata tools for this. I don't have the videos on the server where the script will run, and I want to upload them directly to youtube from a remote URL, instead of downloading them first... Do you know if this possible?

Short answer: Not possible. Long answer: Videos are just data files. So the question becomes: is it possible for a program on Computer A to tell Server B to send a file to Server C using standard internet communication? YouTube only accepts POST requests for uploading videos, so Server B would need to send this request. And you can't tell Server B to do this with just a URL.

I have a problem I've been dealing with lately. My application asks its users to upload videos, to be shared with a private community. They are teaching videos, which are not always optimized for web quality to start with. The problem is, many of the videos are huge, way over the 50 megs I've seen in another question. In one case, a video was over a gig, and the only solution I had was to take the client's video from box.net, upload it to the video server via FTP, then associate it with the client's account by updating the database manually. Obviously, we don't want to deal with videos this way, we need it to all be handled automatically. I've considered using either the box.net or dropbox API to facilitate large uploads, but would rather not go that way if I don't have to. We're using PHP for the main logic of the site, though I'm comfortable with many other languages, especially Python, but including Java, C++, or Perl. If I have to dedicate a whole server or server instance to handling the uploads, I will. I'd rather do the client-side using native browser JavaScript, instead of Flash or other proprietary tech. What is the final answer to uploading huge files though the web, by handling the server response in PHP or any other language?

It is possible to raise the limits in Apache and PHP to handle files of this size. The basic HTTP upload mechanism does not offer progressive information, however, so I would usually consider this acceptable only for LAN-type connections. The normal alternative is to locate a Flash or Javascript uploader widget. These have the bonus that they can display progressive information and will integrate well with a PHP-based website.

Use JSON. My argument is that JSON maps directly to and from native data types in common scripting languages. If you use Python, then None <-> null, True <-> true, False <-> false, int/float <-> Number, str/unicode <-> String, list <-> Array and dict <-> Object. You feel right at home with JSON. If you use PHP, there should be similar mappings. XML is always a foreign language for any programming language except Scala.

Depending on your needs, you could use both. For example, using XML bindings you get the (de)serialization of the data going across the wire for free. That is, if you're going to be POSTing lots of data to your web-service, and want to avoid calling the equivalent of "request.getParameter" for each parameter and building your own objects and creating/registering different servlets for each endpoing, the bindings can save in development time. And for the response, you can have the payload be defined as a String and return JSON text, which gives you the benefits of that compact, javascript-friendly of that notation.

I'm trying to send username and password data from a web form to my server.

9,742,351

The HTTPS channel over which you send the password to the server provides encryption that is good enough. However, you need a more secure storage mechanism for the password. Use an algorithm like "bcrypt" with many thousands of hash iterations (bcrypt calls this the cost factor, and it should be at least 16, meaning 216 iterations), and a random "salt". This works by deriving an encryption key from the password, which is a computationally expensive process, then using that key to encrypt some known cipher text, which is saved for comparison on future login attempts. Also, using HTTPS on the login only is not sufficient. You should use it for any requests that require an authenticated user, or that carry an authentication cookie.

The messages have to be encrypted using public and private keys and a X.509 certificate should be created for each user, this certificate is stored by the third party. I'm currently sending messages between users through a sockets. Could someone suggest an easy to understand library that I could use to perform simple encryption? Any appropriate reading sources about the library will help as well.

I ended up using M2Crypto after trying PyOpenSSL the problem with PyOpenSSL is that it doesnt have a method to return a public key. I was having a lot of problem with this. M2Crypto has its own encryption method as well, meaning you dont need to install multiple libraries :)

I have a multi threaded python application communicating with a separate service trough UDP. Each thread is similar, at some point need a response from the separate service. So practically for each thread I create e new client socket and start to communicate. The problem is on the server side each UDP packet seems to come from the same reception port thus this create problem on the client side on who receives whose message. How can I enforce the socket to use a different ephemeral reception port for each instance in the same program different threads? Thanks!

You can connect() each UDP socket to it's target. That way the ephemeral ports will be fixed (and different) for each thread.

In my latest Python project, utilizing Twisted, I've tried to be good at using the unittest module. At a high level, I'm building two RESTful APIs designed specifically to talk to each other. For most requests, I can just use DummyRequest and test the rendered values against an expected constant and that's been working fine. However, I've got a few cases where the design requires a request on one server that (among other things) then sends a request to the other server, but doesn't really care about the response. What matters is that the request happens. Like I said, I can test that functionality on the other side perfectly fine, but I'm getting stumped on how to test to ensure that the data was sent over. My ideas so far are either Set up a dummy test server that just checks to see if the request was made and validates the input - Seems flaky and too much effort Set up a decorator to wrap certain tests and modify urllib.urlopen to report when it was called, what we tried to retrieve, and allow me to simply return a known result there. I'm leaning towards the second option as it seems more pythonic, but also a bit hacky. Thoughts?

I don't know much about Twisted or how you set up your system under test, but could you start two servers on a single thread? One of them would be the one you are testing and another would be just a dummy that can accept any request. In addition to that, the dummy would store info that it has received the call. After initiating the operation on the first server that causes it to call the second one, you could then assert that the second one has received a request.

I am working out how to build a python app to do image processing. A client (not a web browser) sends an image and some text data to the server and the server's response is based on the received image. One method is to use a web server + WSGI module and have clients make a HTTP POST request (using multipart/form-data). The http server then 'works out' the uploaded image and other data that the program can use. Another method is to create a protocol that only sends the needed data and is handled within the application. The application would be doing everything (listening on the port, etc). Is one of these a stand-out 'best' way (if yes, which one?), or is it more up to preference (or is there another way which is better)?

false

In my opinion HTTP is an ideal protocol for sending files or large data, and its very common use, easy to suit any situation. If you use a self-created protocol, you may find it hard to transform when you get other client needs, like a web API. Maybe the discussions about HTTP's lack of instantaneity and agility make you hesitate about choosing HTTP, but that mostly something about instant messaging and server push, there are better protocols. But when it comes to stability and flexiblity, HTTP is always a good choice.

I have a working application using python and zeromq and I would like to optimize it. Briefly, a master node send the same request to all workers (about 200) and the then collect the answers. Based on the answer, it sends a message back to one node and the node answers back. Right now I implemented a very simple pattern. Each worker has one REP socket and the server has a list of REQ sockets. The server iterates through all sockets sending the general message and then iterates through all sockets to collect the answers. Finally, based on the answers the server picks one worker, sends a message to it and waits for the reply. This is, of course, quite slow. The slowest part is sending 200 times the same message. Collecting is also slow. The solutions that I have found to distribute tasks and collect answers do load balance which is not what I need. I need that each worker receives the message and responds. What is the pattern recommended for this situation? Thanks

I have developed a server that serves audio files over HTTP. Using the Content-Length header I was able to view the current position, but this source isn't seekable. How can I make it seekable?

Think about what you're asking: A stream of bytes is arriving over the network, and you want random access over it? You can't. What you can do is implement buffering yourself, which you could do reasonably transparently with the io module. If you want to seek forward, discard the intermediate blocks; if you want to seek backward, you'll have to hold the stream in memory till you don't need it anymore. If you don't want to buffer the entire stream client-side, you need a way to tell the server to seek to a different position and restart streaming from there.

What you need is u"http://www.besondere-raumdüfte.de/".encode('idna'). Please note how the source string is a Unicode constant (the u prefix). The result is an URL usable with urlopen(). If you have a domain name with non-ASCII characters and the rest of the URL contains non-ASCII characters, you need to .encode('idna') the domain part and iri2uri() the rest.

I'm using urllib2.urlopen() to open sometimes potentially large files. I have a signal handler to catch SIGTERM, but is it possible to actually interrupt urlopen() when it's downloading a big file to close my program immediately, without waiting for the call to finish?

false

9,897,647

0

urlopen returns a file-like object. Data is only sent over the network when you make a .read() request on this object. (Your OS does some buffering of network data, so this isn't strictly true, but it's close enough for all practical purposes.) So simply use the .read() method's capability to read data in chunks using a loop, perhaps 16K or 64K at a time, rather than retrieving the whole file at once. In your signal handler, then, you can close the file-like object and the file will stop downloading after the current chunk finishes. The smaller the chunk you use, the less latency there will be in stopping the download. I'd use a global variable to hold the reference to file-like object so it is accessible in your signal handler; in this case it seems like the simplest solution. If you should happen to try to read from the file-like object after closing it, you will get an exception, which you can handle gracefully.

Basically a browser hosted python notebook, where the code gets evaluated on a different machine.

I'm making an application in Python and using Amazon Web Services in some modules. I'm now hard coding my AWS access id and secret key in *.py file. Or might move them out to an configuration file in future. But there's a problem, how can I protect AWS information form other people? As I know python is a language that easy to de-compile. Is there a way to do this? Well what I'm making is an app to help user upload/download stuff from cloud. I'm using Amazon S3 as cloud storage. As I know Dropbox also using S3 so I'm wondering how they protects the key. After a day's research I found something. I'm now using boto (an AWS library for python). I can use a function of 'generate_url(X)' to get a url for the app to accessing the object in S3. The url will be expired in X seconds. So I can build a web service for my apps to provide them the urls. The AWS keys will not be set into the app but into the web service. It sounds great, but so far I only can download objects with this function, upload doesn't work. Any body knows how to use it for uploading? Does anyone here know how to use key.generate_url() of boto to get a temporary url for uploading stuff to S3?

Don't put it in applications you plan to distribute. It'll be visible and they can launch instances that are directly billable to you or worst..they can take down instances if you use it in production. I would look at your programs design and seriously question why I need to include that information in the app. If you post more details on the design I'm sure we can help you figure out a way in which you don't need to bundle this information.

This will not work, as you will always must have your client responding. I suggest using the client (eg. in html using javascript) to make a connection (ping) every minute from your script on the client to your server, and in your cronjobs letting a script run every x minutes to update the clients that didn't within x.

There is absolutely no point in such checking. You will always have these IPs UP. Just because an android client seldom have a real IP but using Net via some router/proxy. Web is one-way road. To implement a heart-beat feature you have to make your android clients to ping server.

I would point out that depending upon what site you are on, there may be a more efficient way (perhaps an exposed web service) than scraping data from the page and working with mechanize/selenium to do what you want. If you are on the web, browser driver tools are the hammers, and they will get the screws in the wood, but sometimes another tool will work better.

urllib2 is the appropriate way to post data if you're looking for python standard library. Django doesn't provide a specific method to do this (as well as it shouldn't). Django goes out of it's way to not simply reinvent tools that already exist in the the standard library (except email...), so you should never really fear using something out of the python standard library. requests is also great, but not standard library. Nothing wrong with that though.

I have a small website hosted by my university. The policy is that no server side scripting language (e.g. PHP, etc.) is enabled, hence websites are either static or can use client side scripting (e.g. javascript, etc.). I also can't touch the server/configure it/install things. Anyway, I wanted to add some data from other websites (namely, google scholar citations) that I manage to scrape with Python+lxml, dynamically. Is there any way I can have these data dynamically queried - on the client side of course? I tried using IronPython to embed my Python code in my webpage, but it was complaining about failing to find the lxml imported library. But a similar solution would be great. Or a library in pure javascript which allows for opening and parsing external webpages...? Thanks!

You could create a class that has an index number of the line from seed_list.txt, the URL, and where the data from the web. An object of this type can be created with the line number and URL, then it is passed to the worker thread which will put the data into the object, and then the object is passed to a write thread which will order the objects by the line number and output the data as necessary.

You can run a special thread which outputs data and interact with it through a queue. I mean your 'crawling' thread will not write a result to a text file but put it to the queue. This 'output' thread can sort/filter your results.

Remark: Doing CN=sAMAccount,base_dn) is not valid because the user can be somewhere in another sub-tree. Which is the proper way of getting the DN for an user for which I do have the sAMAccount?

The search result contains: A list of search result entries. Each search result entry in the list contains the distinguished name of the entry and a (partial) attribute list or A list of search result references. Each search result reference contains a sequence of URIs After the entries or references comes a single search result done message. Therefore, if any entries matched, they are returned in the list of search result entries, each of which contains the distinguished name of the entry that was matched. Your python API documentation should contain information as to how to extract the distinguished name of the entry that matched.

I am trying to build a simple email client with python and IMAPClient. The problem is that the folder names aren't uniform for all servers. If i mark an e-mail as spam, it has to be moved to the spam/junk folder from the inbox folder (?) .. but i am unable to do that because i don't know what the folder name would be (Spam or INBOX.junk or [Gmail]/Spam ) How do other email clients work with varying folder names ?

Roundcube have this in both the server and user configuration. I don't know about other mail clients, but I guess they either use heuretics, either by just looking at what folders there are or by using knowledge about the particular IMAP server.

I believe that for common EMail providers they have a mapping as to what that provider uses by default (gmail, hotmail, exchange etc.). Another way of doing it is to let the user decide first time, persist the setting for that account and not ask again. Mixed approach would be to try and detect all common variations and use the first valid one you encounter. If there are more then one simply allow user to choose.

You have several options here: Close the listening socket from another thread - the accept() will raise an exception if it fails. Open a local connection to the listening socket - that makes the accept() return by design. Use an accept mechanism that can block on more than one synchronization object so that the wait can be signaled to return without a connection. Use a non-blocking alternative to accept(), (async like AcceptEx() and overlapped IO on Windows).

I need to navigate though a website that is written mostly in Javascript. There are no hard links at all, as the page is simply modified through the script. I can do what I need to using Javascript injections one after another, but chrome starts searching for my input instead of injecting it after a certain string length. I've tried to use frames to do this in HTML, but chrome won't let me use Javascript inside the frame since the source is from a different domain. Is there a good way that I can do this? I've looked into using Java or Python, but I don't see anything that lets you work with Javascript. EDIT: Thanks for telling me about different software, but I don't want to use other third-party software. I would really like to know how to execute Javascript injections in a systematic manner from a HTML page. I can do it from the browser, so why can't I do it from an HTML document?

You can use a tool like Selenium to emulate a user clicking things in a web browser (I believe it actually "drives" a real instance of whatever browser you choose.) Selenium has a domain-specific language for specifying what actions you want to perform, and Python bindings for controlling it programmatically. I haven't actually used it, so I can't say much more about it, but you should go check it out.

Seems you're looking to cache queries made to your site. After calculating a response, save a record with the request url, method, params, and response in a your preferred storage. Depending on your environment and the number of requests, your may choose a database or filesystem. However, you need to take into account that some of the result data may change, in which case you'd need to remove cached data that depend on that data.

Workers process one request at a time. You have a few options: 1) You can run multiple workers (this is the most common method). Workers sit in poll() when they aren't processing so this model works pretty well. 2) Write a fork() implementation around the worker. This way you can fire up a set number of worker processes, but don't have to monitor multiple processes.

The goal is to collect the MAC address of the connected local NIC, not a list of all local NICs :) By using socket and connect (to_a_website), I can just use getsockname() to get the IP, that is being used to connect to the Internet. But from the IP how can I then get the MAC address of the local NIC ? Main reason for the question is if there are multiple NICs.

false

10,137,594

Another roundabout way to get a systems mac id is to use the ping command to ping the system's name then performing an arp -a request against the ip address that was pinged. the downfall to doing it that way thou is you need to write the ping response into the memory of python and performing a readline operation to retrieve the ip address and then writing the corresponding arp data into memory while writing the system name, ip address, and mac id to the machine in question to either the display or to a test file. Im trying to do something similar as a system verification check to improve the automation of a test procedure and the script is in python for the time being.

I have an application I am developing on top of GAE, using Python APIs. I am using the local development server right now. The application involves parsing large block of XML data received from outside service. So the question is - is there an easy way to get this XML data exported out of the GAE application - e.g., in regular app I would just write it to a temp file, but in GAE app I can not do that. So what could I do instead? I can not easily run all the code that produces the service call outside of GAE since it uses some GAE functions to create the call, but it would be much easier if I could take the XML result out and develop/test the parser part outside and then put it back to GAE app. I tried to log it using logging and then extract it from the console, but when XML is getting big it doesn't work well. I know there's bulk data import/export APIs but seems to be an overkill for extracting just this one piece of information to write it to data store and then export the whole store. So how to do it in the best way?

I have developed a few python programs that I want to make available online. I am new to web services, and I am not sure what I need to do in order to create a service where somebody makes a request to an URL (for example), and the URL triggers a Python program that displays something in the user's browser, or a set of inputs are given to the program via browser, and then python does whatver it is supposed to do. I was playing with the google app engine, which runs fine with the tutorial, and was planning to use it becuase it looks easy, but the problem with GAE is that it does not work well (or does not work at all) with some libraries that I plan to use. I guess what I am trying to do is some sort of API using my WebFaction account. Can anybody point me in the right directions? What choices do I have in WebFaction? What are the easiest tools available? Thank you very much for your help in advance. Cheers

Well, your question is a little bit generic, but here are a few pointers/tips: Webfaction allows you to install pretty much anything you want (you need to compile it / or ask the admins to install some CentOS package for you). They provide some default Apache server with mod_wsgi, so you can run web2py, Django or any other wsgi frameworks. Most popular Python web frameworks have available installers in Webfaction (web2py, django...), so I would recommend you to go with one of them. I would also install supervisord to keep your service running after some reboot/crash/problem. I would be glad to help you if you have any specific question...

This has nothing to do with download speed. XPath //* selects the entire page. XPath //script/text() selects only text inside script elements. So of course the second one is faster, because there is less text to search with the re() call!

I am afraid that you might look for 'something' in the entire document, so you probably should still use hxs.select('//*').re('something'). And about the speed question: the answer is that if you look for the word 'something' in a document which is 4k large, of course it will take longer then filtering the document for text() and after looking for that word within that text.

My experience has been that any sufficiently useful test framework will end up needing a customized logging solution. You are going to end up wanting domain specific and context relevant information, and the pre-baked solutions never really fit the bill by virtue of being specifically designed to be generic and broadly applicable. If you are already using Python, I'd suggest looking in to the logging module and learning how to write Handlers and Formatters. It's actually pretty straight forward, and you will end up getting better results than trying to shoehorn the logging you need in to some selenium-centric module.

No you cannot do that: the field names are keys in a Python dictionary, in what you write the second invoice_line will overwrite the first one this would mess up OpenERP's ORM anyway as it does not handle relations to different tables. So you need two different columns, one relative to account.invoice.line and the other to account.service.line. If you really need a merged view, then you can add a function field which will return the union of the invoice and service lines found by the two previous fields. But I'm not sure the forms will be able to handle this.

Store their last activity in a database table when they are active. You can use mouse movement, keypresses, or some other activity to update the timestamp. Periodically poll that table with an ajax call on the page on which the user would see their online/offline status. If the last active time is > 5 minutes, show them as offline or idle.

Everything that happens when the user is NOT on your side is impossible to track (luckily). So not this is not possible (think about the security). UPDATE Now that I think of it. It is possible, however very unlikely that you can do it. If your name would have been Google you would have come a long way, because lots of websites use Google analytics. But other than that: NO not possible for reasons mentioned.

if I am on such a thing I use either the HTML5 Visibility API or fallback to blur and focus events observing when the user left the page and then returns... leaving means unfocus the browser window or tab (but still keeping the page open) but since you wanna react on inactivity... hmmm you could start a timeout (of course that would need a global event delegation for many events to stop it if something happens like submit, click, change, mousemove and so on)

I need to set up a page that will let the user upload a file, modify the file with a script, and then serve the file back to the user. I have the uploading and modifying parts down, but I don't know where to put the file. They are going to be in the area of 1 or 2mb, and I have very little space on my webhosting plan, so I want to get rid of the files as soon as possible. There's no reason for the files to exist any longer than after the users are given the option to download by their browser upon being redirected. Is the only way to this with a cron job that checks the creation time of the files and deletes them if they're a certain age? I'm working with python and PHP. edit: First the file is uploaded. Then the location of the file is sent back to the user. The javascript on the page redirects to the path of the file. The browser opens save file dialog, and they choose to save the file or cancel. If they cancel, I want to delete the file immediately. If they choose to save the file, I want to delete the file once their download has completed.

I don't know why I didn't think of it, but I was on an IRC for Python, discussing a completely unrelated issue, and someone asked why I didn't just serve the file. Exactly! I never needed to save the file, just to send it back to the user with the correct header. Problem solved!

I'm new to cgi and python, so I've been making quite a few mistakes. The problem is that if something goes wrong with the script, I just get a 500 error on the webpage. The only way I can see what caused the error is by executing the page via ssh, but the page involves file uploads, so I can't test that part. Is there a way I can output Python errors to a file?

there are a couple of options, use the logging module as directed, you can tail the server's error log, and you can enable cgitb with import cgitb; cgitb.enable() Depending on exactly where the error occurs, the error will show up in different places, so checking all three, and using print statements and exception blocks helps to debug your code. With file uploads, I've found I have to explicitly state enctype="multipart/form-data" in the form tag or it breaks, often quietly.

In my case I'm using the Dropbox API. Currently I'm storing the key and secret in a JSON file, just so that I can gitignore it and keep it out of the Github repo, but obviously that's no better than having it in the code from a security standpoint. There have been lots of questions about protecting/obfuscating Python before (usually for commercial reasons) and the answer is always "Don't, Python's not meant for that."

Don't know if this is feasible in your case. But you can access the API via a proxy that you host. The requests from the Python APP go to the proxy and the proxy makes the requests to the Dropbox API and returns the response to the Python app. This way your api key will be at the proxy that you're hosting. The access to the proxy can be controlled by any means you prefer. (For example username and password )

There are two ways depending on your scenario: If you are developing a web application for end users, just host it in a way that your API key does not come to disclosure. So keeping it gitignored in a separate file and only upload it to your server should be fine (as long there is no breach to your server). Any obfuscation will not add any practical benefit, it will just give a false feeling of security. If you are developing a framework/library for developers or a client application for end users, ask them to generate an API key on their own.

You can use makefile if you find the file interface of Python convenient. For example, you can then use methods like readlines on the socket (you'd have to implement it manually when using recv). This can be more convenient if sending text data on the socket, but YMMV.

I am guessing you will have to set up your own proxy service for this, i.e set up your entire API and OAuth logic on a server outside your own country. If you call this proxy service from within your own country it is probably not apparent that you are actually communicating with Twitter. You will need some sort of cryptographic layer between your client and your proxy/relay service though to make it somewhat secure/obscure. Your own request signing mechanism so to say, and your proxy/relay endpoint should definitely talk (HTTPS/SSL).

I am having weird behaviors in my Python environment on Mac OS X Lion. Apps like Sublime Text (based on Python) don't work (I initially thought it was an app bug), and now, after I installed hg-git, I get the following error every time I lauch HG in term: *** failed to import extension hggit from /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-package/hggit/: [Errno 2] No such file or directory So it probably is a Python environment set up error. Libraries and packages are there in place. Any idea how to fix it? Notes: I installed hg-git following hg-git web site directions. I also added the exact path to the extension in my .hgrc file as: hggit = /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-package/hggit/ Python was installed using official package on Python web site.

newbie here in need of help. Using App Inventor amd App Engine. Learning python as i go along. Still early days. Need to post text data from AI to app engine, save in blob store as file (.xml), to be emailed as an attachment. Am able to send pictures using Shival Wolfs wolfwebmail2, and am sure with a bit of playing with the code i can change it to save the text post as a file in blob store to do the same operation. As stated newbie learning fast. Many thanks in advance for any pointers.

The solution I found was to do nothing with shival wolfs code on app engine, and to replace the 'postfile' block in the app inventor code with a 'posttext' block with the text you want to send attached to it. Also change the filename variable to the name you want the file called including file type (i.e. .xml, .csv, .txt etc). This appears to work for me.

Yes, it's possible to send the same info as the browser does. Depending on how the browser communicates with the server, it could be as simple as adding username and password as HTTP POST parameters. Other common methods are for the browser to send a hash of the password, or to log in with more than one step.

I'm working on a script which involves continuously analyzing data and outputting results in a multi-threaded way. So basically the result file(an xml file) is constantly being updated/modified (sometimes 2-3 times/per second). I'm currently using lxml to parse/modify/update the xml file, which works fine right now. But from what I can tell, you have to rewrite the whole xml file even sometimes you just add one entry/sub-entry like <weather content=sunny /> somewhere in the file. The xml file is growing bigger gradually, and so is the overhead. As far as efficiency/resource is concerned, any other way to update/modify the xml file? Or you will have to switch to SQL database or similar some day when the xml file is too big to parse/modify/update?

No you generally cannot - and not just XML files, any file format. You can only update "in place" if you overwite bytes exactly (i.e. don't add or remove any characters, just replace some with something of the same byte length). Using a form of database sounds like a good option.

not really sure what you want to happen but if your going to implement this kind of feature in a website I think you should use a flash application instead of python (or if possible html 5). though your using python on the development of you web app it would only run on the server side instead and the feature you want to use is on a client side so for me it's more feasible to use flash instead to capture the video then after capturing the video you upload it to your server then your python code will do the rest of the process on the server side.

I have an issue when trying to test a web application with Selenium/Python. Basically I can't test elements of a pop-up window. A scenario: I can test all elements for a page. But when I go to click on a button that opens up a small pop up box I can't test the elements on the popup. It's like the pop up isn't in focus or active. I can test elements on the next page. For example click a button, brings me on to next page, and I can work with elements on the 'next' page. So it the problem seems to be popup specific. I could post code but to be honest it might confuse at this stage. I may post code in a later post, thanks

For the Selenium RC API, you need to use the SelectWindow command to switch to the pop-up window. The window can be specified either by its name (as specified on the JavaScript window.open() function) or its title. To switch back to the main window, use SelectWindow(None).
