- InnoDB Fast Index Creation now works with mysqldump,
OPTIMIZE TABLE. (Alexey Kopytov)
innodb_extra_rsegments was removed because the equivalent,
innodb_rollback_segments, has been implemented in MySQL 5.5. (Yasufumi Kinoshita)
- Bug #757749 - Using
ALTER TABLEto convert an InnoDB table to a
MEMORYtable could fail due to a bug in the Fast Index Creation patch. (Alexey Kopytov)
- Bug #764395 - InnoDB crashed with an assertion failure when receiving a signal on
pwrite(). The problem was that InnoDB I/O code was not fully conforming to the standard on
POSIXsystems. Calls to
pwrite()can be interrupted by a signal. In such cases, InnoDB would crash with an assertion failure, rather than just restarting the interrupted call. (Alexey Kopytov)
- Bug #766236 - A crash was occurring in some cases when
innodb_lazy_drop_tablewas enabled with very large buffer pools. (Yasufumi Kinoshita)
- Bug #733317 -
SYS_STATSinternal table of XtraDB has been expanded for supporting
innodb_stats_methodfrom InnoDB -plugin. (Yasufumi Kinoshita)
The version of Percona XtraDB shown in logs is not correct. The actual version is 1.1.6-20.2 (instead of 1.1.6-20.1).
