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 with wsrep_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 report Invalid 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.
