#1494399: Fixed issue caused by replication of events on certain system tables (for example,
mysql.slave_relay_log_info). Replication in the Galera eco-system is now avoided when bin-logging is disabled for said tables.
As part of this fix, when bin-logging is enabled, replication in the Galera eco-system will happen only if
BINLOG_FORMATis set to either
STATEMENT. The recommended format is
STATEMENTis required only for the
pt-table-checksumtool to operate correctly. If
BINLOG_FORMATis set to
MIXED, 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 user
nobody), which can be used by
garbdin the event it is started from a directory that
garbdcannot write to.
- #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. Although
garbdis configured to use the
base_dirvariable, it was not registered due to a bug. Until
garbdis fixed, you should start each instance from a separate working directory.
