Percona Server version 5.1.55-12.6 is now available for download. It is now the current stable release version.

Changes

  • Fixed compiler warnings in both the core server and in XtraDB. (Alxey Kopytov, Yasufumi Kinoshita)

Bugs Fixed

  • Bug #602047 – The ROWS_READ columns of TABLE_STATISTICS and INDEX_STATISTICS were not properly updated when a query involved index lookups on an InnoDB table. (Yasufumi Kinoshita)
  • Bug #707742 – The server could crash when trying to import a table which had not been previously prepared using xtrabackup --prepare --export. Also, on servers with huge buffer pools, adding or removing an index even on an empty InnoDB table could take a long time due to excessive locking when innodb_dict_size_limit was non-zero. Locking was relaxed to alleviate this. (Yasufumi Kinoshita)
  • Bug #724674 – Ported an updated version of the original implementation of the Excessive Function Calls, which removes some fcntl calls to improve performance.  (Oleg Tsarev)
