Bugs Fixed¶
- Node eviction in the middle of SST now causes the node to shut down properly.
- After an error during node startup, the state is now marked unsafe only if SST is required.
- Fixed data inconsistency during multi-insert auto-increment
workload on async master with
binlog-format=STATEMENT
when a node begins async slave withwsrep_auto_increment_control=ON
. - Fixed crash when a prepare statement is aborted (due to conflict with applier) and then replayed.
- Removed a special case condition in
wsrep_recover()
that whould not happen under normal conditions. - Percona XtraDB Cluster no longer fails during SST, if a node reserves a very large amount of memory for InnoDB buffer pool.
- If the value of
wsrep_cluster_address
is not valid, trying to create a slave thread will now generate a warning instead of an error, and the thread will not be created. - Fixed error with loading data infile (LDI) into a multi-partitioned table.
- The
wsrep_node_name
variable now defaults to host name. - Starting
mysqld
with unknown option now fails with a clear error message, instead of randomly crashing. - Optimized the operation of SST and IST when a node fails during startup.
- The
wsrep_desync
variable can now be enabled only after a node is synced with cluster. That is, it cannot be set during node bootup configuration). - Fixed crash when setting a high flow control limit
(
fc_limit
) and the recv queue fills up. - Only the default 16 KB page size (
innodb_page_size=16384
) is accepted until the relevant upstream bug is fixed by Codership (see https://github.com/codership/galera/issues/398). All other sizes will reportInvalid page size
and shut down (the server will not start up). - If a node is executing RSU/FTWRL, explicit desync of the node will not happen until the implicit desync action is complete.
- Fixed multiple bugs in test suite to improve quality assurance.
