[debian-mysql] Bug#705154: mysql-server-5.5: non-zero exit status from /etc/init.d/mysql start when /etc/mysql/debian-start echoes no text

[Andrew Basterfield]

Package: mysql-server-5.5
Version: 5.5.30+dfsg-1
Severity: normal
Tags: patch

When /etc/mysql/debian-start echoes no text the value of $output /etc/init.d/mysql:120 is zero-length. This causes [ -n "$output ] to fail and as we are under set -e we exit the script at that point with a non-zero exit status.

 output=$(/etc/mysql/debian-start)
 [ -n "$output" ] && log_action_msg "$output"

This will cause apt to fail configuration of the package.

I would suggest the following to fix it

 [ -n "$output" ] && log_action_msg "$output" || true

This is not a problem with the standard /etc/mysql/debian-start as it echoes copious text but it is not unreasonable to allow a user to silence /etc/mysql/debian-start.
