<pre>This has originally been reported at <a href="http://bugs.debian.org/746151">http://bugs.debian.org/746151</a>
D-Bus-activated units (i.e. having BusName= non-empty) will lose their
bus_name_good bit after daemon-reloading:
x200 ~ $ systemctl dump | perl -nlE 'say if /joss.service:$/ ... /^->
.*.service/' | grep Bus
BusName: org.freedesktop.timedate1
Bus Name Good: yes
x200 ~ $ sudo systemctl daemon-reload
x200 ~ $ systemctl dump | perl -nlE 'say if /joss.service:$/ ... /^->
.*.service/' | grep Bus
BusName: org.freedesktop.timedate1
Bus Name Good: no
When using “systemctl reload” on the service and the control command SIGCHLDs,
service_sigchld_event() will call service_enter_running(s, SERVICE_SUCCESS),
but the following if condition will fail and therefore the last branch is taken
instead of the first one:
if ((main_pid_ok > 0 || (main_pid_ok < 0 && cgroup_ok != 0)) &&
(s->bus_name_good || s->type != SERVICE_DBUS))
service_set_state(s, SERVICE_RUNNING);
else if (s->remain_after_exit)
service_set_state(s, SERVICE_EXITED);
else
service_enter_stop(s, SERVICE_SUCCESS);
I am not sure how to properly fix this, which is why I’m creating this report.
Thanks in advance for any fixes :).</pre>
