| | | | | | | | | | | | | | | | | | | | | 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-43859: Take MODE_IX locks for collection creation.Daniel Gottlieb2019-11-261-0/+2
| | | | | | | | | | | | | | | | | Two concurrent storage transactions can now create collections with the same collection name. These transactions will conflict at commit time; the first committer will win and register their collection into the global catalog. The losing transactions will bubble a WriteConflictException. Top-level callers that should fail if the collection already existed must now check and fail with a NamespaceExists error code. Previously, those callers could rely on lower level code returning the NamespaceExists error. Callers that were implicitly creating a collection may retry the operation, using the now-registered collection. These transaction-local collections (UncommittedCollections) are returned when doing any CollectionCatalog::lookup* call.

| | | | | | | | | | | - Don't use MONGO_INITIALIZER to declare each fail point. We only need one init task in total: freeze and iterate the registry. - remove MONGO_FAIL_POINT_DECLARE macro (extern) - remove MONGO_FAIL_POINT_SHOULD_FAIL macro (FailPoint::shouldFail) - remove MONGO_FAIL_POINT_BLOCK_IF (FailPoint::executeIf) - remove MONGO_FAIL_POINT_BLOCK (FailPoint::execute) - clean up FailPointRegistry and fail_point_service implementation.

* SERVER-38499: Enforce oplog visibility at the MongoDB layer.Daniel Gottlieb2019-01-241-0/+12
| | | | | | | | | | | | | | | | | | | | | | | WiredTiger guards against transactions preparing with a timestamp earlier than the most recent reader. This guarantees no reader may have seen the wrong version of a document. The oplog is a special case. Because the oplog does not contain prepared updates, and oplog readers cannot read from other collections, it's valid to prepare behind an oplog readers timestamp. However, WiredTiger is not aware the oplog is special. When MongoDB uses WiredTiger `read_timestamp`s to enforce oplog visibility, there are cases (specifically, secondary oplog application) where an oplog reader can be in front of an impending prepare. There were two strategies available for resolving this. The first is to artificially hold back what oplog is available to read at until nothing can be prepared behind an oplog reader. The second strategy, which is what this patch does, is to have the MongoDB layer hide documents that are newer than the visibility point. The mechanism for calculating and discovering the visibility point is unchanged.
