# ==== Purpose ==== # # Test verifies that when an admin command execution is interrupted by KILL # command it should stop its execution. The admin command in binary log should # contain only the list of tables which have successfully executed admin # command prior to kill. # # ==== Implementation ==== # # Steps: # 0 - Create two table t1,t2. # 1 - Execute OPTIMIZE TABLE t1,t2 command. # 2 - Using debug sync mechanism kill OPTIMIZE TABLE command at a stage # where it has not optimized any table. # 3 - Check that OPTIMIZE TABLE command is not written to binary log. # 4 - Using debug sync mechanism hold the execution of OPTIMIZE TABLE after # t1 table optimization. Now kill the OPTIMIZE TABLE command. # 5 - Observe the binlog output, the OPTIMIZE TABLE command should display `t1,t2`. # 6 - Please note that, we binlog the entire query even if at least one # table is modified as admin commands are safe to replicate and they will # not make the slave to diverge. # # ==== References ==== # # MDEV-22530: Aborting OPTIMIZE TABLE still logs in binary log and replicates to the Slave server. # --source include/have_log_bin.inc --source include/have_debug.inc --source include/have_debug_sync.inc --source include/have_innodb.inc --echo # --echo # Kill OPTIMIZE command prior to table modification --echo # RESET MASTER; CREATE TABLE t1 (f INT) ENGINE=INNODB; CREATE TABLE t2 (f INT) ENGINE=INNODB; --connect(con1,127.0.0.1,root,,test,$MASTER_MYPORT,) --connection con1 SET debug_sync='admin_command_kill_before_modify SIGNAL ready_to_be_killed WAIT_FOR master_cont'; --send OPTIMIZE TABLE t1,t2 --connection default SET debug_sync='now WAIT_FOR ready_to_be_killed'; --let $thd_id= `SELECT ID FROM INFORMATION_SCHEMA.PROCESSLIST WHERE INFO LIKE '%OPTIMIZE TABLE %'` # Now kill. --replace_result $thd_id THD_ID eval KILL $thd_id; SET debug_sync = 'reset'; --disconnect con1 --source include/show_binlog_events.inc DROP TABLE t1,t2; RESET MASTER; --echo # --echo # Kill OPTIMIZE command after table modification --echo # CREATE TABLE t1 (f INT) ENGINE=INNODB; CREATE TABLE t2 (f INT) ENGINE=INNODB; --connect(con1,127.0.0.1,root,,test,$MASTER_MYPORT,) --connection con1 SET debug_sync='admin_command_kill_after_modify SIGNAL ready_to_be_killed WAIT_FOR master_cont'; --send OPTIMIZE TABLE t1,t2 --connection default SET debug_sync='now WAIT_FOR ready_to_be_killed'; --let $thd_id= `SELECT ID FROM INFORMATION_SCHEMA.PROCESSLIST WHERE INFO LIKE '%OPTIMIZE TABLE %'` # Now kill. --replace_result $thd_id THD_ID eval KILL $thd_id; SET debug_sync = 'reset'; --disconnect con1 --let $wait_binlog_event= OPTIMIZE --source include/wait_for_binlog_event.inc DROP TABLE t1,t2; let $binlog_file= query_get_value(SHOW MASTER STATUS, File, 1); FLUSH LOGS; --let $MYSQLD_DATADIR= `select @@datadir` --exec $MYSQL_BINLOG $MYSQLD_DATADIR/$binlog_file > $MYSQLTEST_VARDIR/tmp/mysqlbinlog.out --let SEARCH_PATTERN= OPTIMIZE TABLE t1,t2 --let SEARCH_FILE= $MYSQLTEST_VARDIR/tmp/mysqlbinlog.out --source include/search_pattern_in_file.inc --remove_file $MYSQLTEST_VARDIR/tmp/mysqlbinlog.out
