disable mysql service stop on upgrading

[Alex Samorukov]

I think it is better to remove mysql restart in the rpm scripts. when i`m doing rpm -Uvh Percona-XtraDB-server-51-5.1.45-10.rhel5.i386.rpm i don`t need to restart mysql, better to do it later manually.

just checked - there is no restart in RHEL/CENTOS src.rpm, see http://rpm.pbone.net/index.php3/stat/3/srodzaj/2/search/mysql-5.0.77-3.el5.src.rpm

Confirmed. Upgrading binaries requires mysqld restart

restart on package upgrade seems sensible, otherwise just gets confusing at best.

please convince me otherwise :)

[Alex Samorukov (samm-os2)]

Let me try.

1) It is against RHEL policy (look on native mysql-server package)
2) It is too easy to break everything on system update.
3) If user is using plugins or UDF he WILL NEED to recompile them before restart, or server will fail on startup. This is my case, btw.
4) After restart you anyway will need some work, like running mysql_upgrade and checking application.

But 1) is the most important - your package should follow RHEL rules if it is designed for a RHEL system.

Convinced me with (1). We should follow packaging rules. Thanks!

Should this be extended to not start the server after installation? Our current RPM behaviour is to start the server when we install. It should be removed for symmetry.

[Vadim Tkachenko (vadim-tk)]

This behavior is consistent with MySQL RPM packages ( from dev.mysql.com)
I propose we do not change it, hence => Won't fix.

[Stewart Smith (stewart)]

Since our aim is to be completely compatible with the MySQL RPM packages, I agree we should Won't Fix this (although arguing to upstream is most welcome)
