Closed temeo closed 6 years ago

After adding new Galera variable wsrep_open_transactions https://github.com/codership/galera/issues/492 the MTR internal check for the test case galera.galera_as_slave_multisource has started failing:

mysqltest: Result content mismatch

This indicates that either there is an open transaction remaining at the end of the test or that a transaction which is executed by the test does not get properly closed in wsrep patch.

The galera.galera_as_slave_multisource post-test mtr check failure is not due to the merge of mysql-5.7.22 (5b18c9efd00). It has been "failing" before too.
