The systemd System and Service Manager
deb4e7080d
An auto-restarted unit B may depend on unit A with StopWhenUnneeded=yes.
If A stops before B's restart timeout expires, it'll be started again as part
of B's dependent jobs. However, if stopping takes longer than the timeout, B's
running stop job collides start job which also cancels B's start job. Result is
that neither A or B are active.
Currently, when a service with automatic restarting fails, it transitions
through following states:
1) SERVICE_FAILED or SERVICE_DEAD to indicate the failure,
2) SERVICE_AUTO_RESTART while restart timer is running.
The StopWhenUnneeded= check takes place in service_enter_dead between the two
state mentioned above. We temporarily store the auto restart flag to query it
during the check. Because we don't return control to the main event loop, this
new service unit flag needn't be serialized.
This patch prevents the pathologic situation when the service with Restart=
won't restart automatically. As a side effect it also avoid restarting the
dependency unit with StopWhenUnneeded=yes.
Fixes: #7377
