Binlog events were created for the statements for non-InnoDB tables, but they were never cleaned from transaction cache, which could lead to node crash. Bug fixed #1277986.
clustercheckscript would mark node as down on Debian based systems if it was run with default values because it was looking for the
defaults-extra-filein the wrong directory. Bug fixed #1276076.
Deadlock would happen when
NULLunique key was inserted. Workaround has been implemented to support
NULLkeys, by using the
md5sum of full row as key value. Bug fixed #1276424
innodb-data-home-dirare now handled by default (ie., there is no need to set them up in sst_special_dirs). Bug fixed #1276904.
Builds now use system
Zlibinstead of bundled one. Bug fixed #1277928.
If transaction size exceeds the wsrep_max_ws_size limit, there will appear a warning message in the error log and replication is skipped. However, the transaction was committed in the master node, and cluster would be in inconsistent state. Bug fixed #1280557.
Variable wsrep_load_data_splitting defaults to
OFFnow, using it turned
0is not recommended.
Other bugs fixed: #1279844.
