Bugs fixed

Fixed the issues with upgrade on Debian caused by debian-start script. Bug fixed #1112363.

Adding the AUTO_INCREMENT column to a table would result in data inconsistency because different nodes use different auto_increment_offset. Bug fixed #587170.

LOAD DATA INFILE was not replicating properly in cluster. Bug fixed #1206129.

After a COMMIT processing was interrupted (e.g. certification failure) it didn’t always release transactional MDL locks, which could lead to server deadlock while performing DDL. Bug fixed #1212955.

pc.checksum option was enabled by default, although its purpose was just to help with debugging. Bug fixed #1229107.

Server startup isn’t interrupted if the /var/lock/subsys/mysql file was not cleaned up by the init script. Bug fixed #1231067.

State Snapshot Transfer cleanup of existing data directory is now configurable with a cpat parameter. Bug fixed #1231121.

Handler command and concurrent DDL could cause node hanging. The problem would happen when a handler session was aborted due to replication conflict. Bug fixed #1233353.

Command service mysql status was not producing valid exit codes, which could break the configuration management systems. Bug fixed #1237021.

Option wsrep-new-cluster could lead to server crash. Bug fixed #1238331.

No key information was provided for DROP VIEW TOI statement. Bug fixed #1240040.

innodb_locks_unsafe_for_binlog option is no longer checked because slave threads are READ-COMMITTED by default. Bug fixed #1240112.

If IO cache contained the Query_log_event, database pointer would be reset during transaction replay. This could lead to “1046 No database selected.” error when next statement is issued. Bug fixed #1241760.

After test shutting down all the nodes indicate that all write set handlers were not released. Bug fixed #1244661.

MDL locks were not released properly on slaves at commit time. Bug fixed #1245333.

Implemented number of thread pool scheduler fixes. Bug fixed #1240500.

Running FLUSH STATUS would zero-up wsrep_cluster_size and wsrep_local_index variables. Bug fixed #1232789.

Fixed the dependency conflict between the Percona-XtraDB-Cluster-shared and Percona-Server-shared-compat packages. Bug fixed #1084309.

Fixed the memory leak in the wsrep_write_cache() function. Bug fixed #1230160.

Xtrabackup SST Configuration implementation added in Percona XtraDB Cluster 5.5.33-23.7.6 has been renamed xtrabackup-v2, so wsrep_sst_method =xtrabackup will use xtrabackup implementation before 5.5.33-23.7.6 and will be compatible with older Percona XtraDB Cluster versions. Bug fixed #1228618.

Other bugs fixed: bug fixed #1244741, bug fixed #1244667, bug fixed #1243150, bug fixed #1232890, bug fixed #1235244, bug fixed #999492, bug fixed #1245769, bug fixed #1244100.
