Percona Server 5.5.39-36.0¶

New Features¶

Percona Server Audit Log Plugin now supports JSON and CSV formats. The format choice is controlled by audit_log_format variable.

Percona Server Audit Log Plugin now supports streaming the audit log to syslog.

Bugs Fixed¶

Querying INNODB_CHANGED_PAGES with a range condition START_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 an ER_CANT_FIND_SYSTEM_REC and a warning printed to the server error log. The workaround is to add an appropriate END_LSN-limiting condition to the query. Bug fixed #1346122.

mysqld-debug was missing from Debian packages. This regression was introduced in Percona Server 5.5.36-34.0. 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 and NEW 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).
