our current packaging system has a bindip parameter that is set to localhost this effectively means that anyone who upgrades will have their sharding and replication broken because they will only be listening on localhost this should be commented out in the configuration when upgradingthis was changed in and should be reflected in the release notes please follow up with the packaging team on the future of this but for now we should warn and guide people appropriately in both the upgrade page and release notes

the mongo shell prompt should tell one more about contect when connected for example if connected to a mongod and it is a member of a replica set the prompt should tell you the servers state something likeprimaryor secondaryorarbiterif connecting from the shell to an entire set it will be important that the user know which node to which it is currently active so this could be something where myset is the set name host name to which we are connected and primary the state of currentlylikewise with sharding similar things if connected to a mongos we should somehow indicate that maybe sif connected to a mongo in a particular shard indicate connected to a config server indicate that not for but useful lateralso we can make this configurable we can have a prompt js function that returns a string with the above being a default

in some circumstances making a second change to a configuration while it is trying to deploy the first change is not advisable therefore we tried to make this something that users would not do by accidenthowever it seems that users have trouble figuring out to make a change in the case where they need to correct their deployment configuration to make a change the user needs click the edit configuration make the change

its safe to run the setwindowfields stage on each shard independently as long as each partition lives on a single shard that means the shard key must be at least as coarse as the partitionby expression the shard key must be constant within each partition for example given this query codesetwindowfields partitionby state state city city code this is safe to push down if the shard key is any of these state city city state state city all these cases the documents that the partitionby groups together live on the same shard some examples of shard keys that wouldnt allow this state city id id country state city the analysis wed need seems similar to pushing down match past setwindowfields one problem is that we convert setwindowfields with a partitionby to a sort internalsetwindowfields before optimization pushing down the sort wouldnt be valid maybe we should somehow delay introducing the sort until after weve done some optimization maybe we can do something like where we push a lookup down through the mergesort part of a sharded sort

having a collection with elements with a tags array where each element in the array is k v with an index tagsk tagsv query of the form dbcollfindtags elemmatch k somekey v somevalue correctly makes use of the index however a query like dbcollfindtags all does not make use of the index and produces a full scannote the use of all is to allow search matching on more than one tag

currently initial sync ignores any inprogress phase index builds only if it sees commitindexbuild oplog entry during the initial sync oplog replay or during secondary oplog application the index build gets started and committed now the problem is that for two phase index builds with commit quorum on the primary can commit the index build only if my number of ready to commit votes satisfy commit quorum value lets assume my commit quorum is all and its a node replica set to be noted in our todays world initial syncing nodes can vote as a result so consider the below scenario node a is primary node b starts performing initial sync primarynode a starts the index build for collection foobar and votes for itself node b ignores buildinginprogress during initial sync node b finishes initial sync since index build has received only one vote all so it cant commit the index build and keeps waiting for the votes from secondarynode b forevercolor

i believe that mongogridfsdownload overloads should allow ignoring sum altogether not hashing at all for performance reasons this of course should be an optout flag with default still validating sums a little backstory while there is a gridfs module for nginx we would prefer using net backend to nginx wcaching for now since nginxgridfs is a bit limited in functionality we require and is based off the mongodb c driver that is very limited in functionality also so we cant easily extend the module for our needs it turned out that calculcations in net takes most of the cpu time for our gridfs server and we would not like to hack around the api or access collections directly to skip computations to emphasize that this is not recommended maybe the there should be another method instead of a flag for example mongogridfsdownloadunsafe

if an object is returned in the shell from a query or any other way from the server which is then modified the result will be that the id field will be ignored when being sent to a mongodb server in the bson encoding processthis is a bug in javascript shellclient but does not effect the server other than the client not sending the id field it is possible to cause this behavior with javascript on the server using eval dbeval or mapreduce in the reduce phase if the first document in the array is modified which is not a normal usage patternorig descriptiontheres a regression in the shell where if i write an object with my own id the shell ignores it and creates its own objectid i found this out during a data migration today when my previously working js function destroyed an entire tables worth of data

as followon work from we have recently enabled tcmalloc in our evergreen testing this required a local tcmalloc library to be built per machine on a local development machine we would need to export ldlibrarypath to the path of the local tcmalloc library once before compiling wiredtiger binaries however evergreen works a little differently evergreen copies over wiredtiger binaries into different machines and starts to perform testing on them the problem appears because we export the ldlibrarypath to the local tcmalloc library in a different machine we are testing on because the path of the tcmalloc library installed is now different on another machine cant find the location of the library therefore this forced us to update each variants ldlibrarypath to the location of the built tcmalloc when running each test this ticket aims to remove the repetitive setting of ldlibrarypath environment variable through manually patching the wiredtiger libraries elf files post compilation the idea is to patch the tcmalloc path within the wiredtiger libraries into a relative path both patchelf and installnametool change darwin machines commands can be used for this purpose note patchelf is not installed in the evergreen machines and will need to consult build team to install the command

since the topology package will be migrated first it needs to function with both the driver and driverlegacy packages to enable this we need a secondary connection type that implements the legacy functionality this type is called legacyconnection and it handles the glue code necessary for driverlegacy to continue functioning the type should be implemented as outlined above the connectionlegacy method of server returns this type although the actual return type remains a connectionconnection

the transportlayerlegacyendallsessions function takes a lock sessionsmutex this lock is also taken by the transportlayerlegacydestroy method which is called indirectly by the transportlayerlegacylegacysession destructor within endallsessions the sessions list of weak pointers is onebyone promoted by taking a shared pointer to it then processed then the shared pointer is discarded this leads to a pair of difficult to reproduce race conditions on endallsessions the failing case in where the shared pointer is created making the refcount of its object at least other threads dispose of their shared pointers to this object leaving only the shared pointer which was promoted from the weak pointer behind that shared pointer will go out of scope at the end of the loop iteration processing it thus invoking the destructor that destructor will indirectly call transportlayerlegacydestroy which will attempt to take the lock recursively taking a lock in cs mutex class is undefined behavior typical implementations will either deadlock or throw stdsystemerror as encouraged by the standard but this is nonnormative behavior thus the attempt to take the lock in the destroy function will throw an exception which is the precise observed behavior in an entry in the weak pointer list has expired due to the last true pointers to it being destroyed promoting the weak pointer will fail giving a nullptr value for the sharedptr in this case the code skips over empty promoted pointers thus having no failing actions

in certain heavily overloaded environments it is possible to have socket communications undergo timeouts while there are sockettimeout options available in the python driver setting these very high has downsides for socket availability and recycling etc to avoid these situations normal python socket communications allow for an option of setting a socket option of socketkeepalive which results in the sending of keepalive packets that reset the timeout timers on the server side this is a common practice in heavily loaded applications that transmit large amounts of data and where the cpu of the client may be overloaded for various reasonssetting this option is relatively trivial enabling this option involves passing the option through from mongoclient instantiation base behavior can be unaffected since it is an option that only is active when explicitly setfiles affected should be mongoclientpy pass option thru poolpy actually set socket option commonpy validators

we need to update before the ip address change to make sure users are aware and can proactively make changes on their systems

weve seen this problem a lot twitter compass mailing list atlas intercom looks like the problem does not occur with the isolated edition is it possible that on plugin activation we do something with the network eg in compassmetrics that might cause this behavior

initial sync doesnt survive sync sources state transitions in or older under this tests settings i think it is always possible for a node to step down while another node is still syncing from it this is because when at least two nodes are available primary could step down if the other node has higher priority and if the third node is still in initial sync then the initial sync will fail a potential fix would be to set a higher numinitialsyncattempts currently set to for this test and i think this could happen with too
