DURING INNODB RECOVERY Problem: ======= The connection 'master' is dropped by mysqltest after rpl_end.inc. At this point, dropping temporary tables at the connection 'master' are not synced at slave. So, the temporary tables replicated from master remain on slave leading to an inconsistent close of the test. The following test thus complains about the presence of temporary table(s) left over from the previous test. Fix: === - Put explicit drop commands in replication tests so that the temporary tables are dropped at slave as well. - Added the check for Slave_open_temp_tables in mtr_check.sql to warn about the remaining temporary table, if any, at the close of a test.
