New Features

Percona Server has implemented a number of XtraDB Performance Improvements for high-concurrency scenarios.

Percona Server has implemented a number of performance improvements for Page cleaner thread tuning. This feature fixes the upstream bugs: #69170 (#1231918), #70453 (#1232101) and #68481 (#1232406).

ALL_O_DIRECT method for innodb_flush_method has been ported from Percona Server 5.5.

Statement Timeout feature has been ported from the Twitter branch.

Percona Server has extended the SELECT INTO ... OUTFILE and SELECT INTO DUMPFILE to add the support for UNIX sockets and named pipes.

Bugs Fixed

Due to an incompatible upstream change that went in unnoticed, the page cleaner thread would attempt to replay any file operations it encountered. In most cases this were a no-op, but there were race conditions for certain DDL operations that would have resulted in server crash. Bug fixed #1217002.

apt-get upgrade of Percona Server would fail in post-installation step if server failed to start. Bug fixed #1002500.

Percona Server 5.6 now ships with memcached plugins. Bug fixed #1159621.

Fixed the libssl.so.6 dependency issues in binary tarballs releases. Bug fixed #1172916.

Error in install_layout.cmake could cause that some library files, during the build, end up in different directories on x86_64 environment. Bug fixed #1174300.

Server would crash if empty string was passed to AES_ENCRYPT when older OpenSSL version was used. Upstream bug fixed #70489, bug fixed #1201033.

Kill Idle Transactions feature didn’t work correctly if Thread Pool was enabled. Bug fixed #1201440.

Percona Server 5.6.12-60.4 would crash if server was started with Thread Pool feature enabled. Bugs fixed #1201681, #1194097 and #1201442.

Memory leak was introduced by the fix for bug #1132194. Bug fixed #1204873.

A server could have crashed under a heavy I/O-bound workload involving compressed InnoDB tables. Bug fixed #1224432.

A potential deadlock, involving DDL, SELECT, SHOW ENGINE INNODB STATUS, and KILL, has been fixed. Fixed the upstream bug #60682, bug fixed #1115048.

A memory leak in Utility user feature has been fixed. Bug fixed #1166638.

A server could crash due to a race condition between a INNODB_CHANGED_PAGES query and bitmap file delete by PURGE CHANGED_PAGE_BITMAP or directly on the file system. Bug fixed #1191580.

Percona Server could not be built with Thread Pool feature and -DWITH_PERFSCHEMA_ENGINE=OFF option. Bug fixed #1196383.

Page cleaner should perform LRU flushing regardless of server activity. Fixed the upstream bug #70500, bug fixed #1234562.

Fixed the upstream bug #64556 which could cause an unrelated warning to be raised if a query inside InnoDB was interrupted. Bug fixed #1115158.

Other bugs fixed: bug fixed #1131949, bug fixed #1191589, bug fixed #1229583, upstream bug fixed #70490 bug fixed #1205196,upstream bug fixed #70417 bug fixed #1230220.
