Percona Server for MySQL 5.6.44-85.0

NOTE [2019-05-18]: Debian/Ubuntu 5.6.44-85.0-1 packages were replaced today in the repositories with the 5.6.44-85.0-2 because they would reset the root password to an empty string during the upgrade on Debian/Ubuntu (bug #5640). If you upgraded packages on Debian/Ubuntu to the 5.6.44-85.0-1 please upgrade to 5.6.44-85.0-2 and re-set your root password.

New Features:

• New Audit_log_buffer_size_overflow status variable has been implemented to track when an Audit Log Plugin entry was either dropped or written directly to the file due to its size being bigger than audit_log_buffer_size variable.

Bugs Fixed:

• TokuDB storage engine would assert on load when used with jemalloc 5.x. Bug fixed #5406.

• the ACCESS_DENIED field of the information_schema.user_statistics table was not updated correctly. Bugs fixed #3956, #4996.
• postinst maintainer script in percona-server-server-5.6 package did not escape the password properly and as a result would fail to use it. Bug fixed #4572.
• the page cleaner could sleep for long time when the system clock was adjusted to an earlier point in time. Bug fixed #5221 (upstream #93708).
• executing SHOW BINLOG EVENT from an invalid position could result in a segmentation fault on 32bit machines. Bug fixed #5243.
• BLOB entries in the binary log could become corrupted in case when a database with Blackhole tables served as an intermediate binary log server in a replication chain. Bug fixed #5353 (upstream #93917).
• when Audit Log Plugin was enabled, the server could use a lot of memory when handling large queries. Bug fixed #5395.
