Bugs Fixed
The buffer pool mutex split patch implemented in Percona Server could cause a race condition, involving a dirty compressed page block for which there is an uncompressed page image in the buffer pool, that could lead to a server crash. Bug fixed #1086680.
If binary log was enabled, Fake Changes transactions were binlogged. This could lead to data corruption issues with deeper replication topologies. Bug fixed #1190580.
Changes made to theRPMscripts for previous Percona Server version caused installer to fail if there were different datadir options in multiple configuration files. Bug fixed #1201036.
Percona Server shared-compatpackage was being built with the 5.1.66 version of the client, which didn’t work withOpenSSL. Fixed by building theshared-compatpackage with a more recent version. Bug fixed #1201393.
Fixed the upstream bug #69639 which caused compile errors for Percona Server withDTrace version Sun D 1.11provided by recentSmartOSversions. Bug fixed #1196460.
Fixed a regression introduced in Percona Server 5.5.32-31.0, where server wouldn’t be able to start if Atomic write support for Fusion-io devices was enabled. Bug fixed #1214735.
Percona Server used to acquire the buffer poolLRUlist mutex in the I/O completion routine for the compressed page flush list flushes where it was not necessary. Bug fixed #1181269.
