as part of we plan to remove support for opquery for all commands except hello and legacy hello but it turns out that many drivers and the server itself also use opquery for authenticationrelated commands saslstart and saslcontinue although it is not mentioned in the scope document as part of the implementation of this project saslstartcontinue are still allowed to be executed with opquery the motivation according to was that the repl code was still using opquery and we didnt want to take the time to modify that code it turns out this helps drivers as well still there is a small problem that still remains some drivers including the latest release of the java driver which is the most popular on atlas execute the buildinfo command as part of the handshake its a long story and this command is also executed with opquery so the request of this ticket is to add buildinfo and its cousin buildinfo to the list of commands that are still allowed to be executed with opquery

from to the server has stopped returning the value field from a findandmodify command under certain conditions this is causing the net driver for instance to throw an exception where null used to be returned certainly we could alter the driver to check if the field exists first but this is a change to the servers api and affects all versions of the net driver currently released

we have lots of places throughout the frontend code where we link to another page by referencing its url or make an ajax call to some endpoint referencing a hardcoded url for example noformat httpgetuitaskhistory project taskname function noformat and noformat noformat this is bad because it means if we want to change the url structure we have to update frontend code across the whole codebase for example if we were to try to get rid of the ui in all the urls it would be a huge pain in the ass better approach would be to have some utility angular service perhaps that can generate a url for any endpoint on the server so the code above might look something more like noformat httpgeturlstaskhistoryproject taskname function noformat or noformat noformat

this would allow mongodb to fix a bug described in our request would be to provide either a cursor or session configuration option that allows a cursor to return the last or more generally the first key in a table even keys that are not visible we do not need the value

hii have an application that is virtually partitioned on a relational database mysql and we are moving to mongo we have accounts with an accountid partition field i have a question surrounding our design approach with moving to mongowe currently hoped to give each account its own database and then have a central account manager db to control routing this appears to be working really well and performance is awesomewe could not find any limit anywhere on db numbers per installation there was a reference to the file access limits which we increased to on our ubuntu installationshould we collapse all accounts into a single db using an account key field apply combined indexes etc and then rely on autosharding or is it ok to continue to create new databases per account to reduce the index overheads for large accountsyour help is much appreciated

we track cursors by object location so if an object is deleted we can advancewe werent keep these isolated by db so if a cursor is open at position x on db a and a delete on db b removes an object at position x a segfault can happen because a cursor will be advanced to an illegal positionthis is exacerbated by replication because once an oplog rolls over every time we add an op we delete one so it makes the odds of this higher

a project stage which excludes a field that does not exist in the input document naively removes that field from the output document in practice this has the effect of adding a new field to the output with value missing while this is usually invisible to the client since the missing field will be discarded when the document is serialized to bson the unexpected addition of this new field can negatively impact the behaviour of downstream pipeline stages in the example below for instance we exclude a nonexistent field b before attempting to insert new fields abc into the document via the addfields stage normally the new fields are added in the order they are specified but because the exclusion has already spuriously added an empty field b the ordering of the fields in the output document changes to bac inclusions of nonexistent fields do not produce these missing entries and therefore do not manifest this bug code dbtestinginsertid writeresult ninserted dbtestingaggregate id a b c dbtestingaggregate id a b c dbtestingaggregate id b a c code

we always want reads against mongo to succeed if there is at least one standard or passive node of the replica set alive however in dbtcpconnectors call handling if an ioexception occurs against the chosen dbport the logic in error that calls checkmaster will cause an error if the master is also unavailable this checkmaster needs to be conditional based on slaveok being set that is if slaveok is true in the call method the check should be checkmastertrue false so that the list of hosts is refreshed even if it results in no master being found

ive attached a code snippet here weve been experiencing connection issues in our production application since switching to c for our main mongo processing toolafter a large read ie select all from table documents the c driver throws a no host is known error and crashes or a server ip xxxxxxxxx is no longer connectedin the aftermath of this event i decided to test our database by inserting a large number of records using a very simple c console application as shown in the screenshot attached it makes about inserts and then throws the same error continues to fail inserts a few more records and then fails constantly foreverthis occurs on a mongo db instance setup on amazons it also occurs on a free mongolab db and a high availability mongolab db

per the latest version of the design retryable internal transactions will run in internal sessions with lsid of the form id uid txnnumber txnuuid as supposed to id uid txnnumber stmtid so we should remove stmtid from the internalsessionfields struct make getparentsessionid only check for txnuuid update unittests and jstests that use lsids of the form id uid txnnumber stmtid

multiwrites in a sharded cluster updatemanytrue and justonefalse for deletes do not perform version checking on account that they are broadcast to all nodes in the sharded cluster such operations attach the special value chunkversionignored to indicate that an operation is coming from a router as opposed to direct connection to a shard but that the shard must not perform version checking under the assumption that the caller knows what they are doing however chunkversionignored still triggers a staleshardversion exception in the case where the shardversion is unknown or if the shard is in a critical section the former is not a big problem since it only happens once for the duration of a shards mongod process but the latter is problematic since it may exhaust the retry attempts that we allow on the router this ticket is to comeup with a scheme so that multiwrites staleshardversion exceptions be retried at the level of the shard and not bubble up all the way up to the router

in mongocsharp driver there was an option to delete documents in fschunks collection using gridfs object but in mongodb driver how can we delete documents from only fschunks is it okay to delete documents in fschunks without using gridfs bucket object ie by using codejava databasegetcollectionfschunks code thanks in advance irshad

i am implementing a mongo database to store and manage our users files we currently have gigs of files i have transfered and stored all the files into the database everything went smooth i shutdown the server and went away for a few hours came back and it was running fine again i shut it down to test it and started it back up i have been sitting here for almost hour and it is still not loaded i have decided to store all my files into individual buckets depending on the project record so i have buckets i used an object id for bucket name with files stored in each one i have set the chunk size to i will have a replica set with this solution

on it was made that the following commands are ran with a sessionid txnnumber attached shardsvrcreatecollectionparticipant shardsvrdropcollectionparticipant shardsvrrenamecollectionparticipant shardsvrrenamecollectionparticipantunblock however binaries did not attach it yet so for backwards compatibility those commands do not enforce that they are run as a retryable write after branches out we will be guaranteed that no more binaries that do not attach the sessionid are in the cluster this ticket is to enforce that those commands are run with sessionid txnnumber

currently the bson package depends on the bsonx package which is a reverse of the dependency we should have a stable package should not be depending on an unstable package if possible therefore we need to reverse the dependency to reverse the dependency the tests for the bsonx types need to be moved from the bson package to the bsonx package and the usage of bsonx types within the other tests for the bson package need to be changed to use bsoncore or bsonprimitive types

helloassuming i have a database boo with sharding enabledand collection uri with the compound index sharded by key want to presplit the collection only using doesnt mattersince the system doesnt allow to split by partial shard key i read here that you can split in the following way dbruncommand split boouri middle dbruncommand split boouri middle dbruncommand split boouri middle this works perfect on the mongo console but since im working with the mongodb client and i need to send the maxkey somehow it fails to workattached the script i used to test the splitting after having the db and collection indexed and sharded readyit includes various tries and the response from mongohow can i solve thishow do i serialize maxkey properly and get it to workthanks in advance
