quite useful as there might not be enough information for it
after the statement has been processed. Better to handle retrying
on DBMS side. Also removed after_statement_result enumeration and
return plain int from after_statement().
of background rollback. The separate call is necessary as all of
the resources may not have been released before the execution
reaches after_rollback() call and background rollbacker needs
to notify the client thread after all is complete.
The interface method can be used to notify the DBMS implementation
about state changes in well defined order. The call will be done
under server_state mutex protection.
* Added after applying call for high priority threads in order to
avoid client mode complexity in after_statement() call and
make high prio transaction cleanup possible
* Mask connection failed error with deadlock error if provider
returns connection failed and the transaction was BF aborted
* Pass condition variable for client_state
* Notify all cond waiters when changing the transcation status to
aborted
* Wait for aborting transaction state aborted in before_command
* Added bootstrap service call to do DBMS side bootstrap operations
during the cluster bootstrap.
* Added last_committed_gtid() to provider interface
* Implemented wait_for_gtid() provider call
* Pass initial position to the server state
this should be dealt with the provider. However, only one
thread is allowed to call pause at the time to keep track
of implicit desyncs when pausing the provider.
* Propagate server max protocol version to provider init options
* Store gtid from connected call to make cluster id and the connect
position available
Depending on the DBMS client session allocation strategy the
client id may or may not be available when the client_session
is constructed, therefore there should be a method to assign
an id after construction. Close/cleanup methods were added to
clean up open transactions appropriately.
