Anyway to tell if a job was stopped on purpose?

[Alexander Petrov]

Hi Mike,

>> - A user stopped the job (stop job)
In this case pre-stop will be called (in the 2nd and 3rd case only
post-stop will be called)
* With this stanza, whenever the main script/exec exits, without the goal
of the job having been changed to stop, the job will be started again. This
includes running pre-start <http://upstart.ubuntu.com/cookbook/#pre-start>,
post-start <http://upstart.ubuntu.com/cookbook/#post-start> and
post-stop<http://upstart.ubuntu.com/cookbook/#post-stop>.
Note that pre-stop <http://upstart.ubuntu.com/cookbook/#pre-stop> will not
be run.

>> - The job died repeatedly, passing the respawn limit and stayed down
upstart will send 'stopped' event with RESULT=failed (env variable).
You can write a job-failhandler which is called in case if you job exhaust
respawn limit and totally failed :

* start on stopped job-A RESULT=failed

I have a feeling that in upstart 1.5 that variable was available from
post-stop of a failed job but in upstart 1.10 it isn't true.
BTW, second case doesn't lead to a 'stopped RESULT=failed' event. Second
case won't lead to this in case if pre-stop succeeded.

Guess `failhandler` job is usual way to do what you want (
