Bugs Fixed:
- 1494399: Fixed issue caused by replication of events on certain system tables (for example,
mysql.slave_master_info,mysql.slave_relay_log_info). Replication in the Galera eco-system is now avoided when bin-logging is disabled for said tables.
NOTE: As part of this fix, when bin-logging is enabled, replication in the Galera eco-system will happen only ifBINLOG_FORMATis set to eitherROWorSTATEMENT. The recommended format isROW, whileSTATEMENTis required only for thept-table-checksumtool to operate correctly. IfBINLOG_FORMATis set toMIXED, replication of events in the Galera eco-system tables will not happen even with bin-logging enabled for those tables. - 1522385: Fixed GTID holes caused by skipped replication. A slave might ignore an event replicated from master, if the same event has already been executed on the slave. Such events are now propagated in the form of special GTID events to maintain consistency.
- 1532857: The installer now creates a
/var/lib/galera/directory (assigned to usernobody), which can be used bygarbdin the event it is started from a directory thatgarbdcannot write to.
Known Issues:
- 1531842: Two instances of
garbdcannot be started from the same working directory. This happens because each instance creates a state file (gvwstate.dat) in the current working directory by default. Althoughgarbdis configured to use thebase_dirvariable, it was not registered due to a bug. Untilgarbdis fixed, you should start each instance from a separate working directory.
