Bugs Fixed¶
Manipulating the
innodb_track_redo_log_now
variable dynamically would crash the server if it was started withoutinnodb_track_changed_pages
enabled. This variable is available on debug builds only. Bug fixed #1368530.A potential crash in handling corrupted tables with
innodb_corrupt_table_action
warn
orsalvage
values has been fixed. Bug fixed #1426610.If the user had duplicate pid-file options in config files when running
yum upgrade
, the upgrade would stop with error because it would think it found the duplicate pid while it was the same pid specified twice. Bug fixed #1454917.On some filesystems server would not start if XtraDB changed page tracking feature was enabled and
innodb_flush_method
variable was set toO_DIRECT
. Bugs fixed #1500720 and #1498891.When User Statistics are enabled, executing any statement of the
SHOW
family with non-empty result, would bumpUSER_STATISTICS
ROWS_FETCHED
column values erroneously. Bug fixed #1510953.Fixed the conflicting meta packages between 5.1, 5.5, and 5.6 release series in Debian and Ubuntu distributions.
percona-server-server
andpercona-server-client
meta packages now point to the latest 5.6 release. Bug fixed #1292517.
INNODB_CHANGED_PAGES
table was unavailable with non-defaultinnodb_data_home_dir
setting if the variable had a trailing slash. Bug fixed #1364315.
UPDATE
statement could crash the server with Support for Fake Changes enabled. Bug fixed #1395706.Changing
innodb_fake_changes
variable value in the middle of a transaction would have an immediate effect, that is, making part of the transaction run with fake changes enabled and the rest with fake changes disabled, resulting in a broken transaction. Fixed by making anyinnodb_fake_changes
value changes becoming effective at the start of the next transaction instead of the next statement. Bug fixed #1395579.Startup would fail due to a small hard-coded timeout value in the init script for the pid file to appear. This has been fixed by creating default file for Debian init script timeout parameters in
etc/default/mysql
. Bug fixed #1434022.Percona Server would fail to install on CentOS 7 if
mariadb-devel
package was already installed. Bug fixed #1499721.The upstream bug #76627 was not fixed for the
ALL_O_DIRECT
case. Bug fixed #1500741.
