################################################################################ # ==== Purpose ==== # The purpose of this test is to verify that, in single thread replication # mode when applier thread is handling a transaction that interacts with # non-transaction tables, server should not report error when applier thread is # being stopped in the middle of a transaction and able to complete the # transaction with in the timeout which is hard-coded to 60 seconds. # # ==== Requirement ==== # In single thread replication, when applier thread is being stopped in the # middle of a transaction that interacts with non-transactional tables, there # should not be any error if the transaction is able to complete with in the # timeout. When the applier thread is restarted, the timeout should be reset, so # that the next 'stop slave sql_thread' statement again gives a 60 seconds # interval for non-transactional statements to complete. Also replica should # be stopped successfully. # # ==== Implementation ==== # 1. Create source-replica topology and initial setup on source. # 2. Execute insert statement followed by STOP SLAVE SQL_THREAD for two times. # 2.1 Execute a statement on source. # 2.2 Verify that applier thread is waiting on debug sync point. # 2.3 Execute 'stop slave sql_thread' and let it wait on debug sync point. # 2.4 Continue applier thread. # 2.5 Continue 'stop slave sql_thread'. # 2.6 Execute 'start slave sql_thread'. # 3. Cleanup. # # ==== References ==== # BUG#33646899: MTS + STOP SLAVE SQL_THREAD + group of rep events stops # before 60 sec timeout ################################################################################ source include/have_myisam.inc; source include/have_debug.inc; source include/have_debug_sync.inc; source include/have_binlog_format_row.inc; source include/big_test.inc; source include/not_mts_slave_parallel_workers.inc; --echo # --echo # 1.
