Title:
services should not restart on SIGHUP when running in the foreground
Status in devstack - openstack dev environments:
Confirmed
Status in OpenStack Compute (Nova):
Fix Released
Status in Oslo - a Library of Common OpenStack Code:
Fix Released
Bug description:
As reported on the mailing list (http://lists.openstack.org/pipermail
/openstack-dev/2013-December/022796.html) the behavior of the
ServiceLauncher has changed in a way that breaks devstack.
The work for blueprint https://blueprints.launchpad.net/oslo/+spec
/cfg-reload-config-files introduced changes to have the process
"restart" on SIGHUP, but screen under devstack also uses that signal
to kill the services. That means lots of developers are having to
manually kill services to avoid having multiple copies running.
To fix the problem we should only restart on SIGHUP when not running
in the foreground. There are a few suggestions for detecting
foreground operation on http://stackoverflow.com/questions/2425005
