1############################################################################### 2# Bug#17942050:KILL OF TRUNCATE TABLE WILL LEAD TO BINARY LOG WRITTEN WHILE 3# ROWS REMAINS 4# 5# Problem: 6# ======== 7# When truncate table fails while using transactional based engines even 8# though the operation errors out we still continue and log it to binlog. 9# Because of this master has data but the truncate will be written to binary 10# log which will cause inconsistency. 11# 12# Test: 13# ===== 14# Make master to wait in "open_table" call during the execution of truncate 15# table command and kill the truncate table from other connection. This causes 16# open table to return an error saying truncate failed during open table. This 17# statement should not be binlogged. 18############################################################################### 19--source include/have_debug_sync.inc 20--source include/have_binlog_format_statement.inc 21RESET MASTER; 22--enable_connect_log 23--connection default 24CREATE TABLE t1(id INT AUTO_INCREMENT PRIMARY KEY, a INT, b INT) ENGINE=INNODB; 25INSERT INTO t1(a, b) VALUES(1,2),(2,4),(3,6),(4,8),(5,10); 26SET DEBUG_SYNC = "open_and_process_table signal truncate_before_lock wait_for forever"; 27--send TRUNCATE t1 28 29connect(con1,localhost,root,,); 30SET DEBUG_SYNC = "now wait_for truncate_before_lock"; 31# Wait for one connection to reach open_and_process_table. 32--let $show_statement= SHOW PROCESSLIST 33--let $field= State 34--let $condition= 'debug sync point: open_and_process_table'; 35--source include/wait_show_condition.inc 36 37SELECT ((@id := id) - id) FROM information_schema.processlist WHERE processlist.info LIKE '%TRUNCATE t1%' AND state LIKE '%open_and_process_table%'; 38# Test killing from mysql server 39KILL QUERY @id; 40 41connection default; 42--ERROR ER_QUERY_INTERRUPTED 43--reap 44 45connection con1; 46--source include/show_binlog_events.inc 47 48disconnect con1; 49--source include/wait_until_disconnected.inc 50connection default; 51 52SELECT * FROM t1; 53 54DROP TABLE t1; 55SET DEBUG_SYNC= 'RESET'; 56--disable_connect_log 57
