Bugs Fixed¶
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).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 #1346122.
mysqld-debug
was missing from Debian packages. This regression was introduced in Percona Server5.5.36-34.0
. 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.A server built with system OpenSSL support, such as the distributed Percona Server binaries, had SSL-related memory leaks. Bug fixed #1334743 (upstream #73126).
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.Server would crash on login attempt if
mysql.user
table was truncated. Bug fixed #1322218.
Other bugs fixed: #1337324, #1151723, #1182050, #1182072, #1280875, #1182046, #1328482 (upstream #73418), and #1334317 (upstream #73111).
