| | | | | | multi-document transactions Now that we update the multikey flag within a transaction in a side transaction, the in-memory state about the multikey write will be naturally visible to subsequent writes inside the transaction, so we don't need to keep around any extra structures to enforce this anymore.

| | | | | | replication recovery Now that we execute multikey catalog updates in a side transaction, we need to give them some suitable timestamp. In normal replication, we can grab the latest value of the LogicalClock. In startup recovery, though, we may replay a prepared transaction that does a multikey write, but the LogicalClock may not have been initialized yet. Thus, we use the prepare timestamp of the transaction for the multikey write, since that timestamp is guaranteed to be less than or equal to the commit timestamp of the transaction.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
