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 rollback them thus leading to inconsistencies.
To fix the problem, we automatically rollback 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.
@ mysql-test/extra/rpl_tests/rpl_mixing_engines.test
Enabled item 13.e which was disabled because of the bug fixed by the
current and removed item 14 which was introduced by mistake.
