* SERVER-43859: Take MODE_IX locks for collection creation.Daniel Gottlieb2019-11-261-1/+1
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mutexes in TransactionParticipant This type simplifies and clarifies concurrency control in TransactionParticipant by: (1) Removing TP's own mutexes and using the Session concurrency control rules, instead. That is, certain state is only accessible when the Session is checked out, and requires no further locking. Other state is observable either while holding the client lock or while having checked out the Session. The latter type of state is modifiable only when having checked out the session and locked the client. (2) Separating the two types of state in (1) into separate sub-structures in TransactionParticipant, to make it clear who can access what state, (3) Putting all methods formerly on TransactionParticipant onto new member classes, TransactionParticipant::Participant and TransactionParticipant::Observer. The latter can only read the observable state from (1) above, and the participant may read or modify all of the state. The two types introduced by (3) are designed to enforce proper concurrency control by limiting access of their methods to the underlying TransactionParticipant member variables. The observer type has a private o() method which its other methods are required by convention to use in order to obtain read-only access to the Observable state of the TransactionParticipant. The participant type has the o() method plus an o(WithLock) method that allows mutation of the state while holding the client lock, and a p() method which allows reading and writing of the private state with no other locks. Please see the implementation in transaction_participant.cpp for examples. It is worth noting that with this change, locking the Client is not needed often and never for long, and there is no need for separate mutexes for participant state and monitoring state.

* SERVER-37283 Use stronger locks for system.viewsCharlie Swanson2019-02-111-2/+5
| | | | | | | | | | Readers of the view catalog depend on a MODE_IS DB lock preventing concurrent writes to the view catalog. This is true for regular view maintenance commands like collMod, create, and drop. However, on secondaries these commands are replicated as direct writes to system.views and do not hold as strong of a lock. Further, a user is permitted to write directly to system.views and so could hit a similar issue on the primary.

| | | | | | | | The `MONGO_DECLARE_SHIM`, `MONGO_DEFINE_SHIM`, and `MONGO_REGISTER_SHIM` macros can be used to create specialized types which are customization and auto-registration points for late-binding functions. In some sense they work like weak-symbols; however, they also are useful for tracking dependencies upon shimmed-out implementations.
