# ==== Purpose ==== # # This test checks if an event that is drop implicitly by the scheduler is # written to the binlog. # # ==== Implementation ==== # # The event is first created on the master. # The test sleeps for enough time so that, when the scheduler is enabled, # the event is implicitly dropped because its start and end times have passed. # The slave is synchronized with the master to log this drop. # Finally, another event is created to check if the implicit drop was successful # as it will fail on the slave synchronization, otherwise. # # # ==== References ==== # # BUG#22150112 REPLICATION BREAKS WITH NOT PRESERVE EVENTS --source include/master-slave.inc # Save current event scheduler status SET @saved_event_scheduler= @@GLOBAL.event_scheduler; SET GLOBAL EVENT_SCHEDULER= OFF; CREATE EVENT e1 ON SCHEDULE EVERY 1 SECOND STARTS NOW() ENDS NOW() + INTERVAL 2 SECOND ON COMPLETION NOT PRESERVE DO SELECT 1; # sleep enough so that the event gets dropped automatically when the scheduler # is enabled --let $interval= 2 --let $naptime= `SELECT $interval + 2` --sleep $naptime SET GLOBAL EVENT_SCHEDULER= ON; --echo Wait until the event is dropped to disable the event scheduler again. --let $wait_condition= SELECT COUNT(*) = 0 FROM information_schema.events --source include/wait_condition.inc SET GLOBAL EVENT_SCHEDULER= OFF; --source include/sync_slave_sql_with_master.inc # check that we can create another event with the same name --source include/rpl_connection_master.inc CREATE EVENT e1 ON SCHEDULE EVERY 1 SECOND STARTS NOW() ENDS NOW() + INTERVAL 3 SECOND ON COMPLETION NOT PRESERVE DO SELECT 1; --source include/sync_slave_sql_with_master.inc #cleanup --source include/rpl_connection_master.inc DROP EVENT e1; # Restore the scheduler SET GLOBAL EVENT_SCHEDULER= @saved_event_scheduler; --source include/rpl_end.inc
