Bug#782550: mysql-server-5.5: Use /bin/bash instead of /bin/sh for mysqld_safe

2015-04-14 Thread Frédéric Brière
I forgot to mention that this issue only applies to the Debian version
of mysqld_safe (due to 38_scripts__mysqld_safe.sh__signals.patch).

Bug#782550: mysql-server-5.5: Use /bin/bash instead of /bin/sh for mysqld_safe

2015-04-13 Thread Frédéric Brière
Package: mysql-server-5.5
Version: 5.5.41-0+wheezy1
Severity: wishlist

Due to a bug in dash (#782540), mysqld_safe will kill and restart mysqld
if the latter is stopped with SIGSTOP.  Apparently, some VPSes throttle
CPU usage by this mechanism.  Hilarity ensues.

Although this is not a bug in mysql per se, using /bin/bash instead of
/bin/sh (which is often dash) would effectively circumvent this bug,
without (I assume) any noticable impact.  (If you can afford to run
mysqld, surely you can handle bash as well.  g)

Note that mariadb already uses bash, albeit for a different reason (LP:
#675185).
