is kept as a deprecated alias and will be removed in Percona Server 5.7. There were no functional changes for the feature.Percona Server Audit Log Plugin now supports
JSON
andCSV
formats. The format choice is controlled byaudit_log_format
variable.Percona Server Audit Log Plugin now supports streaming the audit log to syslog.
TokuDB storage engine package has been updated to version 7.1.8.
Querying
INNODB_CHANGED_PAGES
with a range conditionSTART_LSN > x AND END_LSN < y
would lead to a server crash if the range was empty with x greater than y. Bug fixed #1202252 (Jan Lindström and Sergei Petrunia).SQL statements of other connections were missing in the output of
SHOW ENGINE INNODB STATUS
, inLATEST DETECTED DEADLOCK
andTRANSACTIONS
sections. This bug was introduced by Statement Timeout patch in Percona Server5.6.13-61.0
. Bug fixed #1328824.Some of TokuDB distribution files were missing in the TokuDB binary tarball. Bug fixed #1338945.
With XtraDB changed page tracking feature enabled, queries from the
INNODB_CHANGED_PAGES
could read the bitmap data whose write was in still progress. This would cause the query to fail with anER_CANT_FIND_SYSTEM_REC
and a warning printed to the server error log. The workaround is to add an appropriateEND_LSN
-limiting condition to the query. Bug fixed #1193332.
mysqld-debug
was missing from Debian packages. This regression was introduced in Percona Server5.6.16-64.0
. Bug fixed #1290087.Fixed a memory leak in Slow Query Log Rotation and Expiration. Bug fixed #1314138.
The audit log plugin would write log with XML syntax errors when
OLD
andNEW
formats were used. Bug fixed #1320879.Combination of Log Archiving for XtraDB, XtraDB changed page tracking, and small InnoDB logs could hang the server on the bootstrap shutdown. Bug fixed #1326379.
--tc-heuristic-recover
option values were broken. Bug fixed #1334330 (upstream #70860).If the bitmap directory has a bitmap file sequence with a start LSN of one file less than a start LSN of the previous file, a debug build would assert when queries were run on
INNODB_CHANGED_PAGES
table. Bug fixed #1342494.
Other bugs fixed: #1337247, #1350386, #1208371, #1261341, #1151723, #1182050, #1182068, #1182072, #1184287, #1280875, #1338937, #1334743, #1349394, #1182046, #1182049, and #1328482 (upstream #73418).
