I have completed a merge of MySQL 5.1.39 into MariaDB. The merge is pushed into lp:~maria-captains/maria/mariadb-5.1-knielsen for testing. Note that pushing the merge into main is currently blocked by a regression introduced in MySQL 5.1.39 by the patch for Bug#45261. I mailed the MySQL developers about this: http://lists.mysql.com/internals/37377 Due to this regression, the new TIME_MS column in INFORMATION_SCHEMA.PROCESSLIST in MariaDB is broken, as seen in test failures like main.create. Hopefully the MySQL developers can help on how to resolve this. The issue is a bit complex, concerning truncation issues with DECIMAL types. - Kristian.
