4.54. How do I get qrunner to run under daemontools?

It is possible to run qrunner under daemontools, but you have to do a little setup. Because of the fact that mailmanctl forks, you can't use it to start and stop the qrunner processes under daemontools. The solution is to run /usr/local/mailman/bin/qrunner directly.

To start, create a directory called /usr/local/mailman/supervise:

 mkdir /usr/local/mailman/supervise

We will need two scripts in this directory. The first should be called /usr/local/mailman/supervise/run, and should contain the following text:

 #!/bin/sh
 exec setuidgid mailman ./qrunner

Now, create /usr/local/mailman/supervise/qrunner with the following text:

 #!/bin/sh
 # execute a pass through the queues once per minute
 while `/bin/true`; do
    # perhaps code to check for and remove locks should go here???
    /usr/local/mailman/bin/qrunner --runner=All --once
    sleep 60
 done

We should fix up the permissions on this directory now. This is not strictly necessary, but it will stop check_perms from complaining:

 cd /usr/local/mailman
 chmod 2755 supervise
 chmod 755 supervise/*
 chown mailman:mailman supervise -R

Finally, just link /usr/local/mailman/supervise into your /service directory:

 ln -s /usr/local/mailman/supervise/ /service

The qrunner process should start within 5 seconds. Use svstat to verify things are working properly.
