i was attempting to submit a manual patch build for evergreen project is also mongophpdriver this pr was originally opened against the master branch but later rebased on which happens to be the first branch when our evergreen config was introduced i noticed that github didnt register any automatic evergreen patch build for the pr so i attempted to manually submit a patch from the command line using evergreen p mongophpdriver resulted in which restricted me to selecting teststandalonessl and testreplicasetauth tasks on a subset of build variants these appear to correlate with github patch definitions in our project configuration using evergreen patch p mongophpdriver t testatlas to manually specify the actual task i wanted to test resulted in which had the same restrictions finally i used evergreen patch p mongophpdriver v all t all to create the ui had the same restrictions as before before giving up i decided to use the schedule all tasks button from this patchs listing in and that appears to have done the job im curious if there is an explanation for what i experienced here eg ui bug something to do with rebasing the pr im not sure if its pertinent but our project configuration does have disable patching checked i didnt toggle the option so i believe its been set that way since our project was first configured i couldnt find an explanation of that option in the evergreen wiki so im not clear how it might impact what i was trying to do if it is intended to actually disable patch submission it begs the question as to how i was able to schedule a patch build and how evergreen patch was allowed to create a patch in the first place | 0 |
in an configuration with multiple databases if records are inserted into collections of one database records from unrelated collections may be inserted into yet other unrelated collections there may also be rearrangements in collections in the original database but i can not determine this as readily as all records in the same database have an id of the same name so i have been using idname existsfalse to find the errorsthe logs frequently show errors indicating a bad bson object type and extremely long strings further validate does not always find the errors and returns ok when errors are still present other than inserting a couple hundred thousand records into a couple collections at the same time with the java driver i have not found a specific way to reproduce this error but i can provide a valgrind logthe bad records do not seem to be inserted with any client insert calls and the journal file does not repair the collections | 1 |

currently we have the document to convert a replica set to a sharded cluster as below however it doesnt cover the scenario when the replica set has authentication enabled for a sharded cluster the user credentials are stored in the admin database on the config servers so if auth is enabled there would be some extra steps to dump the user credentials from the original replica set and then restore them to the config servers via mongos | 1 |

it is my understanding that in server the only log format supported is json while this format has undisputable benefits when it is parsed by machines its readability by human beings is often significantly inferior to the old text format for example the following log output is produced when a server starts code i sharding marking collection adminsystemroles as collec tion version i sharding marking collection adminsystemversion as coll ection version i storage createcollection localstartuplog with genera ted uuid and options capped true size i index index build done building index id on ns loc alstartuplog i sharding marking collection localstartuplog as collect ion version i ftdc initializing fulltime diagnostic data capture with directory i storage createcollection localreplsetoplogtruncateaf terpoint with generated uuid and options i index index build done building index id on ns loc alreplsetoplogtruncateafterpoint code and the following is the same output

building index indexname on ns nssattrindexnameidnsslocalsystemrollbackid code a quick glance at the log is sufficient to determine what is happening index builds the log is a wall of text and i cannot get a quick assessment for what the logs are saying at all in other words i need to carefully read each log entry to figure out what it is referring to in my opinion the loss of readability is due to the log entries becoming much longer this increases the amount of text that must be processed while the effective payload remains the same since the log entries have become longer frequently the important information is no longer in the first or so columns that a user likely has in their view this means the user either has to scroll right all the time or the user has to read the logs with lines wrapped wrapping lines loses the structure that the text format provided timestamp severity facility etc aligned vertically even more and makes the logs again harder to read the information is no longer presented continuously because of the separation of formatting strings and the data for example index build done building index id on ns localstartuplog became msgindex build done building index indexname on ns nssattrindexnameidnsslocalsystemrollbackid this means the reader must jump back and forth constantly as they are reading the entries as an engineer who develops drivers for the server as well as a system administrator who reads server logs to troubleshoot the server i find that the loss of realtime logging in text format has a major negative effect on my productivity there are various tools available for converting json logs to text logs ideally i would like to send logs to a program that would output json logs unmodified to one file and convert json log to a text log and store the result in another file while i am unaware of a program that specifically does this this seems like a straightforward problem to solve however there is the challenge of getting the log to such a program the server currently offers three options for log destination stdout syslog file stdout would be the most suitable destination since i would be able to trivially pipe the logs to the log splitter program unfortunately stdout logging is not allowed when fork is used which is the subject of this ticket it is possible to launch the server without fork by manually implementing the daemonization externally but given that i believe there is an easy to implement alternative in the server that allows filepipe output with forking i believe the server should allow logging to stdout when fork is used syslog logging is suitable for production installations when there is only a single mongodmongos process that can be globally configured it is not generally suitable for development because i can have over mongod processes running in various deployments including scratch ones and configuring syslog for each of them is untenable file destination requires the log splitter to know when the log is rotated by the server so that the splitter can reopen the current log file i am not aware how the splitter might be notified of this event by the server directly although i imagine a workaround may be devised by watching for changes in the file system in the log directory the splitter would also need to rename its log files correctly when the server rotates logs which would be errorprone expected behavior as an engineer developing drivers for the server and as a system administrator i would like to have mongodmongos etc be able to log to pipe such as by logging to standard output which i will redirect to a pipe even when the server forks implementation i believe it will be sufficient to prohibit logging to stdout when stdout is a tty if stdout is not a tty in my understanding it is redirected to either a file or a pipe and hence the logs will be consumed by something and will not be lost such that it does not seem necessary to prohibit these cases | 0 |

todays mostly ebs related outage in amazon aws caused the same effect twice in our replica setthe root cause was that the ebs volumes became unavailable which in turn were mounted via mdadm and lvm i can see that the kernel probably leaves the mongo server just unaware or guessing here about whats going on but what happened was that the master didnt step down probably because its network was fine and it didnt lag all clients kept connecting to the node that didnt workwould there be any way for the master or the slaves to detect this situation and fail overnext to that i am not aware of any option to have a slave manually step up either instead of having the master step down in the above scenario the master didnt allow mongo shell access because of the bad data partition leaving no way to tell the master to step down other then powering it offcheers | 0 |

description this behavior is only observable in storage engine desired behavior if an indexed query runs while documents are updated which moves them it is possible for those documents to be missing from the results when using storage engine we would like this behavior to change so that all matching documents which exist through the lifetime of the query are returned even if they are updated in particular we only expect this behavior when those updated documents have values updates in the query which arent changed so the query matches the document in all updated states example see code below add a large document followed by small documents all with letter a add an index on letter remove the large document start a query batch size using index update document to cause it to move to empty space left by large removed document technical details when a query walks an index in it is possible for documents to move behind the current position as document location is stored in the index in as the cursor moves forward resulting in documents being missed this behavior cannot be reproduced in wiredtiger inmemory or encrypted storage engines | 0 |

bsonarraybuilder has a few rather serious performance glitches around subarraystart and subobjstart specificallythese functions require that you provide a name for the element that you wish to start as a string as a result you are forced into a strlen call to populate stringdata and a strtol call to convert the string to an integer and to keep your own external integer counter to convert to a string this is mostly useless the common use case here is just to start the next element in the series and bsonarraybuilder already keeps an internal counteri think you could just havesubarraystart autoincrement to next indexsubobjstart autoincrement to next indexsubarraystartsizet index ok you want to do something fancy use fill etc still no need for strtolsubobjstartsizet index as abovesubarraystart const stringdata strindex do the whole complex dance with strtol fill etcsubobjstart const stringdata strindex as abovethis would let most users never have to worry about this stuff at all since they are starting array elements in order let more advanced users use a more efficient mechanism that avoids string processing when using offsets by providing integer offsets and finally provide a way forward for the more general casefinally what should the behavior be if you specifiy a name index for an element and you are already beyond that many elements in the array it appears that the provided nameis just ignored in this case perhaps that should be an error | 0 |

it seems that the exists operator does not work on keys which have been indexed if a key has an index the exists operator will never return any documents ive attached some tests in ruby which demonstrate this along with their output and an example mongo console session showing that its not just an issue with the ruby driver | 1 |
we would like the intel library to be tested since it is prone to miscompilation which could cause decimal arithmetic in mongo to be incorrect there is an extensive test suite that comes with the library and runs quite quickly a few seconds the intel built in test compiles to a standalone executable its not clear how to best integrate into our test suite we could execute it from a cppunittest or have a separate scons target that is a standalone task on evergreen the self tests are located at and use readtestin as the input they should be built using the same flags as the library libm must be included on some platforms as well for proper functionality ideally these would be integrated into the unittest task however they currently have minor failures on some systems that must be resolved by changing compilation or skipped fails on a edge case not an issue as we do not need this function some inaccuracies with when returning inexact results there are tests which check that the error is expected for this function these are failing we are not sure if the issue is related to miscompilation or is a problem with the platforms pow implementation used underneath besides these systems the selftests have been confirmed to pass on all other evergreen targets | 1 |

during a primary step down we call closeconnection on all matching sessions this kicks those sessions out of sourcemessage which causes them to explicitly call end which calls closeconnection closeconnection calls globalticketholderrelease this causes us to double release on primary step down which causes us to increase the effective number of tickets in the system this behavior is most noticeable when looking at the now open number of connections in the main init and listen thread where the outof param stays steady at the desired number of connections but the available amount increases this causes us to report negative numbers of open connections | 1 |

if a specific index exists it is probably always better to use than the wildcard index if not we should probably warn or maybe even disallow adding the otherwise redundant index one way to do this would be to model the wildcard index purely as a fallback in the queryplanner so that when it would go to use an index on a field but there is no index it can use it will instead make a wildcard scan asif there was that index on that field i think that would also solve noformat dbfooensureindex createdcollectionautomatically true numindexesbefore numindexesafter ok dbfooensureindexa createdcollectionautomatically false numindexesbefore numindexesafter ok queryplanner plannerversion namespace testfoo indexfilterset false parsedquery a eq queryhash plancachekey winningplan stage fetch inputstage stage ixscan keypattern path a indexname ismultikey false multikeypaths path a isunique false issparse false ispartial false indexversion direction forward indexbounds path a rejectedplans stage fetch inputstage stage ixscan keypattern a indexname ismultikey false multikeypaths a isunique false issparse false ispartial false indexversion direction forward indexbounds a serverinfo host silversurferwsl port version gitversion ok noformat | 0 |

this is the follow up ticket from discussion this portion of the ticket investigates the functionality of adding an import thread into testformat stress testing currently the design that is discussed from describes adding an import thread in which will perform live import on the current rundir since import needs a table that is foreign to the rundir database the idea is to createdrop tables in another database in a new subdirectory rundirimport removing the necessity of exclusive access of tables there have been numerous implementation approaches that can be done here the thread will call session drop and then import the same uri onto the table this method is least preferable as no operation can be done on the uri between drop and import and drop would be ebusy most of the time the thread inside will create a new uri table and populate some data into the new uri then call drop on that uri and then import back into the database this is method allows other threads to work on original uri in testformat the thread will somehow copy the existing table uri file that it is performing on and then import the newly copied table this method is most experimental as not sure with the behaviours around copying a live table and importing a copied table file note testformat only performs operations on table continually currently an actual use case here can also provide assistance in designing the import for testformat | 0 |
