Fun with Bugs #43 - Bugs Fixed in MySQL 5.7.13

For some reason I do not see numerous public announcements about recent MySQL 5.7.13 release, even though it happened a couple of days ago formally. Maybe that's because we do not have any really "big" new features in this release (new ->> operator for introduced though for those who, unlike me, care about JSON). Still there are many fixes for bugs previously reported by Community (or Oracle engineers, but still in public bugs database), and I'd like to discuss some of them.

Let me start with the bug that was NOT fixed though, Bug #81093, "mysqld_multi not included in mysql-community-server package", reported by Georgi Iovchev and …

MySQL on Debian and Ubuntu

Debian Linux (the underlying foundation of Ubuntu) manages the startup/shutdown of MySQL quite differently from the ways I am used to. I am a long-time user of both the MySQL binary provided by Red Hat/SuSE (along with Fedora and clones like CentOS and Oracle Enterprise Linux) and the official binary from mysql.com. After the successful restore of a cold backup, I started mysqld using the Debian provided init script. The script said that mysqld failed to start up, but in reality it did start up. Similarly, stopping mysqld fails.

The output below demonstrates the outputs and the behavior seen on a Ubuntu 8.04 LTS Server:

root:~# ps -ef | grep mysqld
root     20165 19926  0 15:12 pts/4    00:00:00 grep mysqld
root:~# /etc/init.d/mysql start
 * Starting MySQL database server mysqld                                            [fail]

OurDelta mysqld_safe patch makes it back into MySQL

Last year, Erik Ljungstrom (sensei in the #ourdelta IRC channel on Freenode) created patch for a bug Arjen identified with the handling of (among others) the open-files-limit option; the patch was first included in the OurDelta build of MySQL 5.0.67.

Now, Sun engineer Guilhem Bichot has committed the (modified) patch into the 6.0-maria tree, so it should appear in 6.0 and potentially 5.4. That’s good.

See http://bugs.mysql.com/40368 for details and history.
