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

[seahawk1986]

Hello,
both systemd packages in the -proposed repository for xenial (229-4ubuntu12) and yakkety (231-9ubuntu1) are sending all the DBus signals I need to track unit state changes, thank you very much for fixing this regression.

  Regression: systemd does not send all queued DBus Signals when a unit
  gets inactive

Bug description:
  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).
