From c21fbff33886644b945337cd155184e80cfcbc93 Mon Sep 17 00:00:00 2001 From: Alfranio Correia Date: Thu, 27 Aug 2009 13:46:29 +0100 Subject: [PATCH] BUG#46864 Incorrect update of InnoDB table on slave when using trigger with myisam table Slave does not correctly handle "expected errors" leading to inconsistencies between the mater and slave. Specifically, when a statement changes both transactional and non-transactional tables, the transactional changes are automatically rolled back on the master but the slave ignores the error and does not roll them back thus leading to inconsistencies. To fix the problem, we automatically roll back a statement that fails on the slave but note that the transaction is not rolled back unless a "rollback" command is in the relay log file. --- .../extra/rpl_tests/rpl_mixing_engines.test | 47 ++++++------------- .../suite/rpl/r/rpl_stm_mixing_engines.result | 45 +++++++++--------- sql/log_event.cc | 9 ++++ 3 files changed, 46 insertions(+), 55 deletions(-) diff --git a/mysql-test/extra/rpl_tests/rpl_mixing_engines.test b/mysql-test/extra/rpl_tests/rpl_mixing_engines.test index 73713b7998b..cbda85527f1 100644 --- a/mysql-test/extra/rpl_tests/rpl_mixing_engines.test +++ b/mysql-test/extra/rpl_tests/rpl_mixing_engines.test @@ -562,21 +562,21 @@ let $binlog_start= query_get_value("SHOW MASTER STATUS", Position, 1); --echo # There is a bug in the slave that needs to be fixed before enabling --echo # this part of the test.
