# ==== Purpose ==== # # Verify that their is no crash any more while executing a # 'CREATE...SELECT' statement even if it is interrupted at # debug point 'mysql_lock_tables_kill_query' in the middle # and 'CREATE TABLE' event was not logged when # binlog_format=row, gtid_mode=off and autocommit=0. # # ==== Implementation ==== # # 1. Disable autocommit. # 2. Create a table with select. # 3. Drop the table from another connection. # 4. Set DEBUG= '+d,mysql_lock_tables_kill_query'. # 5. There is no crash while executing a 'CREATE ... SELECT' # statement even if it is interrupted at the above debug # point in the middle. # 6. Verify that 'CREATE TABLE' event was not logged. # # ==== References ==== # # Bug#21114464 CRASHES WITH CONCURRENT DDL+KILL+BIN LOGGING --source include/have_binlog_format_row.inc --source include/not_gtid_enabled.inc --source include/have_debug.inc --connection default SET SESSION autocommit= 0; CREATE TABLE t1 AS SELECT 1 AS col1; --connect(con1,localhost,root) --connection con1 DROP TABLE t1; --connection default RESET MASTER; SET SESSION DEBUG= '+d,mysql_lock_tables_kill_query'; --error ER_QUERY_INTERRUPTED CREATE TABLE t2 AS SELECT 1 AS col1; SET SESSION DEBUG= '-d,mysql_lock_tables_kill_query'; --echo # Verify that 'CREATE TABLE t2' event was not logged. --source include/show_binlog_events.inc SET SESSION autocommit= 1;
