[Bug 1632964] Re: Regression: systemd does not send all queued DBus Signals when a unit gets inactive

[Martin Pitt]

** Description changed:

  Since the penultimate systemd package update in september (229-4ubuntu8)
  systemd does not send the remaining queued DBus signals (e.g.
  PropertiesChanged) when a unit's state changes to inactive.
  
  Sending those signals has been working since the release of Ubuntu 16.04
  and it is quite unfortunate for my use case this got broken while fixing
  another bug.
  
  Adding this upstream change to the package restores the old
  functionality (a patch for the current systemd package (systemd
  229-4ubuntu10) for xenial is attached):
  https://github.com/systemd/systemd/commit/0dd99f86addd1f81e24e89807b6bc4aab57d5793
  
+ SRU TEST CASE: See comment #8
+ Regression potential: Low; the patch only widens the condition when a change signal is sent, thus at most clients would now get more D-Bus signals than before (in particular, the missing one at becoming inactive).
