* SERVER-52877 Unify how writable Collections instances are handledHenrik Edin2022-04-051-46/+31
| | | | | | | | | | | | | | | | | | | | | CollectionCatalog::LifetimeMode has been removed. Catalog writes now require that we are in an active WUOW. Make it allowed to use WriteUnitOfWork when the server is in readOnly mode. It does not open storage sessions, just allows registration of RecoveryUnit callbacks that are executed when calling commit(). This allows for the unification of code where we need to initialize Collection instances even in readOnly mode. Handling of enforcing readOnly has been pushed down to the RecordStore. All interfaces that perform write now check if we are in readOnly mode and throw if we are. Catalog updates using the BatchedCollectionCatalogWriter class bypass the Collection cloning if the batched CollectionCatalog instance already has a uniquely owned copy (a previous write to this collection has been requested). It is also not required to be in an active WUOW when the BatchedCollectionCatalogWriter is used.

* SERVER-60321 Fix edge cases when setting up state for Lock-free readsHenrik Edin2022-03-041-0/+5
| | | | | | | | | | | | | | | | | | | When LFR is setup we should now always: * Open a storage snapshot * Stash the catalog * Mark the OperationContext that we are in LFR None of the three is done if we are not LFR. This fixes an edge case where the opCtx was marked as LFR when no collection was found and no snapshot or catalog was stashed. A sub op could then stash a catalog that wasn't cleaned up properly when tearing down. Anything that happened afterwords, like the profile logic, now had a stashed catalog when there should be none. Also fixed when we lock for reading on a view that we are not marking the OperationContext to be LFR as we never opened a storage snapshot or stashed the catalog.

* SERVER-60094 Add shard version to internal writeBrett Nawrocki2021-09-211-2/+1
| | | | | | | | | | | | | ReshardingOplogApplicationRules::_applyDelete_inlock() has special logic to, upon removing a document from the temporary resharding collection, move a document from one of the other stash collections (i.e. one associated with a different donor shard) into its place. The runWithTransaction() helper does so by using AlternativeSessionRegion which will construct a separate OperationContext. The write being performed in this separate OperationContext won't have shard version attached for the temporary resharding collection like the original one had. Therefore, call initializeClientRoutingVersions() on this context to set the version.

| | | | | | | 1) Create a nested lock helper to run lock-free if a higher level lock-free operation is already running. 2) Change LockFreeReadsBlock to use a counter rather than a boolean to accommodate out of order lock helper destructors. 3) Only yield lock-free read state in query yield when NOT recursively locked. 4) Change query stages and plan executor to use new nested lock-free lock helper.

| | | | | | | | | | | CSS::getCollectionDescription() safely in AutoGetCollectionLockFree and expand lock-free sharding testing. CollectionShardingState and DatabaseShardingState can now be accessed without a lock via new getSharedForLockFreeReads() functions on their respective interfaces. The shard key will now be available in the AutoGetCollection* RAII types via the CollectionPtr. This allows lock-free reads to acquire a single view of the sharding state to use throughout a read operation.

| | | | | | | | | | | owned by AutoGetCollection RequiresCollectionStage now holds a pointer to CollectionPtr owned by an AutoGetCollection. When we save and restore the executor a new CollectionPtr pointer needs to be assigned. Plan executors can no longer be created with temporary CollectionPtr instances and their interface have been changed to take pointers to avoid binding to rvalues. RequiresCollectionStage no longer loads collections from the catalog and will be in sync with the owning AutoGetCollection.
* SERVER-50145 Collection instances are modified using copy-on-writeHenrik Edin2020-10-081-8/+9
| | | | | | | | When a writable collection is requested from the catalog a cloned instance will be returned. Its lifetime is managed by default in a WriteUnitOfWork and committed into the catalog in a commit handler. In the case of a rollback the cloned and modified collection instance is simply discarded. This removes the need to setup rollback handlers to restore any state written to a collection in the case of a rollback.

* SERVER-50984 Add CollectionPtr to replace usage of const Collection*Henrik Edin2020-09-261-25/+48
| | | | | | | | | | | | It implements a yieldable interface that is used to re-load the Collection pointer from the catalog after a yield that released locks. With lock-free reads and copy-on-write on Collection instances releasing locks without notifying an AutoGetCollection at a higher level may cause its pointers to dangle if a MODE_X writer installs a new Collection instance in the catalog. CollectionPtr should be passed by const reference so a yield can notify all the way up.

| | | | | | | | | | | | | inside a WUOW by default There are three modes when accessing a writable Collection: * Managed in WUOW (default) * Unmanaged (users need to commit/rollback) * Inplace that provides direct access to the Collection in the catalog. (Users need to ensure there's no concurrent operations going on) Added a helper RAII type CollectionWriter that abstract the three modes above and also provides abstraction on different methods of accessing Collections (AutoGetCollection or manual lookups). Writable Collection is aquired lazily when needed (usually inside a WUOW).
