# # BUG # --- # BUG#39753: Replication failure on MIXED + bit + myisam + no PK # # Description # ----------- # Simple statements against a bit column cause failure in mixed-mode # replication. # # Implementation is as follows: # i) A table with two bit fields is created. One of them is a key. # ii) A record is inserted without specifying the key value. # iii) The record is deleted using a where clause that matches it. # iv) repeat i-iii) for bit key that has different size, generating # different extra bits values # v) The slave is synchronized with master # vi) The table is dropped on master and the slave is re-synchronized # with master. # # Step v) made the bug evident before the patch, as the slave would # fail to find the correspondent row in its database (although it did # the insert in step ii) ). # # Obs # --- # This test is based on the "how to repeat" section from the bug report. # # --source include/not_group_replication_plugin.inc --source include/have_myisam.inc --source include/master-slave.inc disable_query_log; call mtr.add_suppression("Unsafe statement written to the binary log using statement format since BINLOG_FORMAT = STATEMENT"); enable_query_log; --disable_warnings # setup DROP TABLE IF EXISTS t1,t2,t3,t4,t5,t6,t7,t8; CREATE TABLE t1 (`bit_key` bit, `bit` bit, key (`bit_key` )) ENGINE=MyISAM; CREATE TABLE t2 (`bit_key` bit(4), `bit` bit, key (`bit_key` )) ENGINE=MyISAM; CREATE TABLE t3 (`bit_key` bit(7), `bit` bit, key (`bit_key` )) ENGINE=MyISAM; CREATE TABLE t4 (`bit_key` bit(8), `bit` bit, key (`bit_key` )) ENGINE=MyISAM; CREATE TABLE t5 (`bit_key` bit(9), `bit` bit, key (`bit_key` )) ENGINE=MyISAM; CREATE TABLE t6 (`bit_key` bit(14), `bit` bit, key (`bit_key` )) ENGINE=MyISAM; CREATE TABLE t7 (`bit_key` bit(15), `bit` bit, key (`bit_key` )) ENGINE=MyISAM; CREATE TABLE t8 (`bit_key` bit(16), `bit` bit, key (`bit_key` )) ENGINE=MyISAM; # insert and delete INSERT INTO `t1` ( `bit` ) VALUES ( 0 ); DELETE FROM `t1` WHERE `bit` < 2 LIMIT 4; INSERT INTO `t2` ( `bit` ) VALUES ( 0 ); DELETE FROM `t2` WHERE `bit` < 2 LIMIT 4; INSERT INTO `t3` ( `bit` ) VALUES ( 0 ); DELETE FROM `t3` WHERE `bit` < 2 LIMIT 4; INSERT INTO `t4` ( `bit` ) VALUES ( 0 ); DELETE FROM `t4` WHERE `bit` < 2 LIMIT 4; INSERT INTO `t5` ( `bit` ) VALUES ( 0 ); DELETE FROM `t5` WHERE `bit` < 2 LIMIT 4; INSERT INTO `t6` ( `bit` ) VALUES ( 0 ); DELETE FROM `t6` WHERE `bit` < 2 LIMIT 4; INSERT INTO `t7` ( `bit` ) VALUES ( 0 ); DELETE FROM `t7` WHERE `bit` < 2 LIMIT 4; INSERT INTO `t8` ( `bit` ) VALUES ( 0 ); DELETE FROM `t8` WHERE `bit` < 2 LIMIT 4; --enable_warnings --source include/sync_slave_sql_with_master.inc # clean up connection master; DROP TABLE t1, t2, t3, t4, t5, t6, t7, t8; --source include/sync_slave_sql_with_master.inc --source include/rpl_end.inc
