Problem: ======== When the mysql.gtid_slave_pos table uses the InnoDB engine, and mysqld starts, it reads the table and begins a transaction. After reading the value, it should end the transaction and release all associated locks. The bug reported in DBAAS-7828 shows that when autocommit is off, the locks are not released, resulting in indefinite hangs on future attempts to change gtid_slave_pos. In particular, the transaction was not properly finalized because thd->server_status was not updated to reflect the end of the transaction. Solution: ======== This patch updates the code to properly commit the transaction after reading gtid_slave_pos during mysqld start-up.
