Restarting nicely with supervisord

I am trying to make supervisorctl restart to work with huey. At the moment, restart doesn’t kill the old process, but still creates another running huey instance.

Below is a terminal capture showing huey is duplicated on restart:

(venv)root@Ubuntu-1204-precise-64-minimal /srv/django/tatianastore # ps -Af|grep -i huey
root     11260     1  0 03:46 ?        00:00:01 python manage.py run_huey --periodic
root     13367  1166  0 03:55 ?        00:00:00 /bin/sh /srv/django/tatianastore/manage_wrapper.sh run_huey --periodic
root     13370 13367  6 03:55 ?        00:00:00 python manage.py run_huey --periodic
root     13378 10409  0 03:55 pts/1    00:00:00 grep --color=auto -i huey

(venv)root@Ubuntu-1204-precise-64-minimal /srv/django/tatianastore # supervisorctl restart tatianastore_huey
tatianastore_huey: stopped
tatianastore_huey: started

(venv)root@Ubuntu-1204-precise-64-minimal /srv/django/tatianastore # ps -Af|grep -i hueyroot     11260     1  0 03:46 ?        00:00:01 python manage.py run_huey --periodic
root     13370     1  2 03:55 ?        00:00:00 python manage.py run_huey --periodic
root     13401  1166  0 03:55 ?        00:00:00 /bin/sh /srv/django/tatianastore/manage_wrapper.sh run_huey --periodic
root     13404 13401 14 03:55 ?        00:00:00 python manage.py run_huey --periodic
root     13433 10409  0 03:55 pts/1    00:00:00 grep --color=auto -i huey

My supervisor config: https://github.com/miohtama/LibertyMusicStore/blob/master/conf/supervisor.conf

Which UNIX signal supervisor needs to send to huey in order to properly stop it? Or are there any special considerations regarding daemonizing huey process?

Alright I was able to replicate this locally and the issue is the fact that you’re using a bash script to run the consumer. When I used a bash script to invoke the consumer, the consumer would continue running indefinitely. When I replaced the bash script with a direct invocation of the consumer, it worked as expected.

So, here is how I would suggest changing your config – I believe this will accomplish the same thing as your wrapper:

[program:tatianastore_huey]
command=/srv/django/tatianastore/bin/python /srv/django/tatianastore/manage.py run_huey --periodic

The info in this comment is a bit outdated: when huey consumer receives SIGTERM, it will not wait for any currently-executing tasks to finish.
