############################################################################### # Bug#21317739: APPLYING CREATE TEMPORARY TABLE SQL ON A SLAVE WITH # REPLICATE-REWRITE-DB FAILS # # Problem: # ======= # As part of fix for BUG#16290902, at the time of writing the 'DROP TEMPORARY # TABLE IF EXISTS' query into the binlog, the query will not be preceded by a # 'use `db`' statement. The query will have a fully qualified table name. # Eg: # 'USE `db`; DROP TEMPORARY TABLE IF EXISTS `t1`;' # will be logged as # 'DROP TEMPORARY TABLE IF EXISTS `db`.`t1`;'. # # Because of this change application of 'replicate-rewrite-db' filter rule # will fail on slave, as it works only on default database specified in 'use' # statement. This causes slave to break when the 'CREATE TEMPORARY TABLE' is # re-executed on slave. # # Test: # ===== # Specify replicate-rewrite-db=test->new_test on slave. On master use 'test' # database and 'CREATE TEMPORARY TABLE 't1'. Then drop the temporary table and # recreate it on master. Now sync master with slave. Slave should be in sync # and up and running. ############################################################################### --source include/master-slave.inc --source include/have_binlog_format_statement.inc # Database 'test' on master is mapped with 'new_test' on slave by using # replicate_rewrite_db filter --source include/rpl_connection_slave.inc CREATE DATABASE new_test; # Create a temporary table on the default database. --source include/rpl_connection_master.inc use test; CREATE TEMPORARY TABLE t1(id int); --source include/sync_slave_sql_with_master.inc # On slave verify that all the queries are rewritten as per the rewrite db # rules. --source include/show_binlog_events.inc # On slave verify that one temporary table is created.
