You said before shutdown triggers are too late but you didn't say why.
I
think that's based on a misunderstanding - but if not, then explain
why it
doesn't work for your scenario.
Hi, thanks for your reply.
I've tried the following:
def sleep(secs):
log.msg('from within trigger')
d = defer.Deferred()
reactor.callLater(secs, d.callback, None)
return d
reactor.addSystemEventTrigger('before', 'shutdown', sleep, 10)
All 'before' trigger are run concurrently. If you're using
`Application` then your `sleep` trigger runs concurrently with the
application's `stopService` trigger (because `Application` has its
stopService added as another 'before' shutdown' trigger alongside
yours).
If you want to delay your application shutdown, you need to cooperate a
little more closely with it. Either attach your application shutdown
code as a callback to the sleep Deferred or move the sleep into the
stopService implementation of one of the services on your application
and trigger the remaining stopService calls (eg the stopService call on
the MultiService you mentioned) when the sleep Deferred fires there.
