maybe i didnt understand very well the rollback part but i think there is a mistake in the first and second possible rollback operation indeed the second paragraph tells me to follow the steps below but i have the impression that the steps are for the first paragraph not the second best regards

in certain situations some helper methods could recursively call poolgetsocket the example helper is databasecollectionnames which gets a socket from the pool and passes it to databaselistcollections listcollections returns a commandcursor which collectionnames immediately fully iterates while still holding the original socket if commandcursor has to send opgetmore to the database a second socket will be required this can cause a deadlock because poolsocketsemaphore uses a lock rather than an rlock which is correct and not the source of the bug fix collectionnames so that it iterates the commandcursor after returning the original socket and look for any other methods that might have a similar problem collectionoptions is a likely candidate the severity of this bug is limited with mongodb since the collection count must be very large to require multiple result sets from the server but can be hit with older versions of mongodb easily by having more than collections in the database collectionnames is called for

the following shell sharding helpers use a write concern of wmajority but do not specify a wtimeout shsetbalancerstate shdisablebalancing shenablebalancing shaddshardtag shremoveshardtag shaddtagrange shremovetagrange this means that users get no feedback if the operations are slow to propagate to a majority of config servers simply adding a wtimeout eg or causes the shell helpers to apparently fail if they take too long in addition to potentially confusing users this causes spurious jstest failures the shell helpers should specify a reasonably low wtimeout eg and then if the operation has timed out due to wtimeout the shell helper should react accordingly ie output a message to notify the user what has happened and commence polling to determine when the write has gone through to a majority eg call gle if possible or do appropriate readconcern majority reads

rocksdb has its own way of doing backups so we didnt plan to support backups from mongodb api at this time however currently a storage engine without backup support fails a lot of tests an example can we skip all the tests that depend on backup functionality if the storage engine doesnt implement it

with multiple mongodb collections grouped inside a single wt table wts random cursor configuration has no way to tell its returning a document that belongs to the collection queried grouping collections into wt tables will not mix with the existing random cursor implementation passing nextrandom to the cursor config current options disregarding feasibility include leave the randomcursor method unimplemented for grouped record stores the query layer has a default walking implementation make calls to wt with a nextrandom cursor this can return a document that does not belong to the collection repeat calls until a valid document is returned add work to wt that allows a random cursor to respect a range of keys to select from a hybrid of the first two may cover most use cases when the collection to sample is small the overhead of a walking cursor is small when a collection is large relative to the entire table sampling random documents from the table will often return one belonging to the collection of interest large collections that are small relative to the table is a usecase not particularly suited to grouped collections

i am writing a virtual filesystem and i am blocked when a string is to be appended to an existing file the file system will emit an event writefdbuflengthposition where position if i am not mistaken i cannot handle this with gridfsbucketwritestream because i cannot start at a certain position alternatively and even better the previous gridfs had a seek method which is very flexible especially if you can go back and forth and read or write from there

after a command cursor is created libmongoc assigns the maxawaittimems and batchsize options to the command cursor i believe we have two options add batchsize as a new command constructor option akin to what we did for maxawaittimems in in this case we could capture batchsize and apply it after the command cursor is created in phongoexecutecommand this will then require changes in phplib to ensure that aggregate also copies batchsize to the new command constructor option instead of adding a command constructor option we can inspect the command document for a batchsize option earlier in phongoexecutecommand and apply it in the same place as above this requires no changes in phplib it also means that the same batchsize value will apply to the original command and subsequent getmore note the second choice inferring batchsize may have implications for where a user had asked if batchsize applied to getmore at all however they did not specifically request the ability to differentiate batchsize options for the initial aggregate and subsequent getmore commands im inclined to go with the second solution inferring batchsize as it requires minimal changes to the phpc api or phplib it also allows us the opportunity to introduce a command constructor option later which would take precedence

the collmod test case is one example specifically when run against a sharded cluster this operation can fail and leave the database or collection not created which in turn causes the rest of the test to fail with a missing database error

the current merge aggressiveness algorithm isnt working well in combination with the recent change to allow bulk loading into an lsm tree the algorithm is a hang over from when each lsm tree had its own set of worker threads

aggregations can involve read precursors stages that lead into write stages we should be able to mirror the read portion without mirroring the write portion additionally we need to figure out how to manage the inevitable cursors generated by aggregation

the doc for applyops currently statesquotethe applyops command is primarily an internal command to support sharded clustersquoteshouldnt that say it exists to support replication rather than sharding

current vast amounts of methods change the default php error handling that throws a warning to throwing exceptions this should not be done because phps general error handling for nearly any function or method albeit in core or in an extension doesnt do this it is incompatible with hhvms error handling in hhvm the parameter parsing happens before the native cfunction is entered this makes it impossible to convert warnings to exceptions even if we wanted to

the new driverconnection interface does not have a method for killing a connection completely as in closing the underlying netconn as opposed to returning the connection to the pool a new interface can extend the driverconnection interface with an expire method that kills the underlying connection or an expire method can be added to the existing interface there should also be an alive method to check if a connection is still alive ie its expire method has not been called

there are reports of databases where the number of preallocated log files grows unbounded in mongodb it does not appear that theyre being used and we keep allocating more one change that appeared in is the new file system interface to get a single file perhaps for windows wtwindirectorylistsingle is not working

currently we break some guarantees of atomicity by using separate wuows for each op and for the final logop this can result in a server performing the modification but not adding it to its oplog if the server is shut down in the middle of an applyops we cant use a single wuow in the general case because applyops needs to support operations like building an index that are illegal inside of a wuow however it should be possible to detect if all ops are simple singledocument crud ops and use a single wuow in that case this would cover all uses of applyops that are used when writing to the config servers

coverity is complaining about multiple places in our code where we do not check the return value of recordstorerestore code recovers from potential state changes in underlying data returns false if it is invalid to continue using this iterator this usually means that capped deletes have caught up to the position of this iterator and continuing could result in missed data if the former position no longer exists but it is safe to continue iterating the following call to next will return the next closest position in the direction of the scan if any this handles restoring after either savepositioned or saveunpositioned virtual bool restoreoperationcontext txn code it looks like all of the cases where we do this are safe and do not need to deal with the capped collections edge case however this is probably an indication that the api for recordstore could be improvedits a bit odd to have a return value that we throw away most of the time

this is a followup ticket for the during the ticket implementation i noticed that sometimes the socket timeout exception is triggered after exceding the time that is mentioned in readtimeout the gap is relatively small the case which i noticed readtimeout but the timeout exception has been thrown only after seconds this situation led to the failed tests which used failpointblocktimems the used workaround when we increased blocktimems from to doesnt contradict to the test idea but we need to investigate the underlying reasons for this behavior and make the full sync of these tests example of changed json test the original json value is

under wire version the current wire version servers have two operation modes if its a partly upgraded server with users created with mongodbcr it will operate in a compatibility mode which with some overhead will allow users to connect using scram to those accounts if the server has been completely upgraded and all users have been migrated to native scram or the server has been freshly brought up on then it will only accept incoming authentication requests using scram mongodbcr requests will be deniedcurrently we only use scram when the max wire version of the server is greater than this means we will currently always use mongodbcr when connecting to a server if the user has not manually specified an authentication mechanism as in the auth method which accepts the username and password as strings we should default to using scram for wire version and allow the server to sort out how to handle it

until is resolved we should skip the one record multiple strings spec test because there is no way to handle it with go without a custom dns lookup solution

in the current fcv upgrade logic the primary node in a replica set executes a command and has the opportunity to acquire strong locks for consistency however the secondaries only get to observe writes to the fcv document which are executed while already holding a hierarchy of locks and as a result they are not allowed to take any further locks on their own out of risk of introducing deadlocks during development we uncovered cases where upgrade requires the acquisition of strong locks on secondaries and because of this it would be much more convenient if the fcv upgrade logic wrote a command oplog entry which on the secondary nodes executes serially

a few modules in the branch of pymongo import unicodeliterals from future this is causing minor problems in the auth module due to expecting a str as its first argument there may be issues in other modules as wellbefore releasing ga we must audit our use of unicodeliterals it may make more sense to remove the future import and work around any issues manuallythe modules to audit are authpy bulkpy and collectionpy

when mongot or mongotmock returns an error which gets propagated by mongod it would be nice if mongod appended something to the error indicating that the error came from another node

first question complicates the answer by mixing locking behavior and granularity of locks this should be split out and lock def should link to wikipedia page with better description in wiki docsyielding happens for more than disk access which was added in and expanded in multiple document writes yield as well as readers periodically this can allow reads during long multidoc write operationsand there are more issues here so it is best if this put back on the list for more review

find show dbs and show collections prints out the json instead of the more friendly output this is probably affecting other commands too in particular find prints the cursor instead of the results

in order to create a new command when starting subsequent batches of grouped writes in the commandwriter we need to create a new bsonobjbuilder and bsonarraybuilder because they cannot be reusedthis functionality is required for bulkwrites

for example if the command was joined here need to also audit what happens when the command is retried but fell into the else branch instead of joining like in the above link the configsvrshardmongos versions of shard collection should probably assert that uuid field always exists

this is a feature request to enhance the behaviour of the sample aggregation command by adding to the plan optimizer the wiredtiger “readonce true” option for mongodb cursors the intended purpose behind this enhancement is so sample does not or is less likely to cache the result set a sample by definition is unlikely to be used again by subsequent samples thereby caching has no benefit and only serves to add unwanted cache pressure and workload contention

it seems like the change in replica set majority calculation introduced in broke balancing on some existing cluster setups since it bases the strict majority on the total number of members not the number of nonarbiter ones we recently upgraded a cluster from to and lost our ability to balance the cluster in its original setup the cluster has shards and each shard is a replica set with four members a primary a secondary and an arbiter in one datacenter and a nonvoting zeropriority hidden secondary with a replication delay in another datacenter after the upgrade balancing the cluster failed since it was waiting for the operations to replicate to a majority out of of the replica set members rather than a majority of the nonarbiter members out of with the third nonarbiter member being on a delay that didnt go very well i expect the same would happen on individual shards if either storage member had become unavailable as a temporary fix to get the balancing going again we removed the replication delay to the offsite secondary not sure if this is the same issue as or just related to it

the version of the driver introduced a regression which can cause corrupted wire protocol messages to be sent to the server in practice the impact of the bug is mitigated by these circumstances occurs when connected to a replica set or multiple mongos using the new ha support for mongos but not a single mongos or a standalone its triggered only if the driver gets an ioexception while performing a normal query not commands and attempts to retry the query if both of these occur it becomes likely that the driver will send corrupted messages to the server and keep sending them until the application is restartedthe affect of sending corrupted messages to the server is undefined in some cases the server will assert and send back an error in others it will crash and in others it will add corrupt documents to the database using objcheck can mitigate the latter case but not fully

the error returned is illegal instruction should fix this by troubleshooting the parameter we pass to g visible here and we should prevent this by testing on a machine after building on a machine

in current mongodbenterprise master the snmp agent does not start with either the snmpmaster or snmpsubagent arguments instead it exits on snmpagent not enabled

the php and hhvm drivers jailbreak the mongoc api and use several private symbols this means that the only way these drivers can be included in linux standard distribution packages is if mongoc ships its private symbols which implicitly makes those symbols public and part of the api this clearly isnt a good idea and there are no intentions for mongoc to move all of its internal symbols into implicit public api that can never change or fixed the php team needs to compile a list of the internal symbols it uses so we can expose these symbols one by one in mongoc in the public api this epic should contain all the symbols and track the progress of moving them into mongoc api and removing them from phongo and hippo

the define definition is wellknown to be a c design problem it has to appear before including headers etc this inverted dependency of a header upon its includer affects considerations of precompiled or c all we have to do is move that definition down below the include files like any other local macro and its much more conventional c if you want to define it in a header and do some logging from inline functions thats ok just undef it at the bottom there is no odr problem if an inline function has statements as long as it always contains the same body which it will nothing bad happens logh can switch from asserting that the macro is defined to asserting that the macro is not defined when logh is included codecxxdefine x include code to codecxxinclude define x code then we dont have a define that must appear before header includes a sideeffect of this is change is that shouldlogs component argument becomes mandatory this is easy to do and only affects or calls
