* a dedicated test for wsrep_retry_autocommit * some galera_toi_* tests were only passing because wsrep_retry_autocommit was in effect. The tests were changed to do not use autocommit * higher timeout values in galera_2nodes.cnf , galera_3nodes.cnf # Conflicts: # mysql-test/suite/galera/galera_2nodes.cnf # mysql-test/suite/galera/r/galera_defaults.result # mysql-test/suite/galera_3nodes/galera_3nodes.cnf
