[Steve Langasek]

Hello Didier, or anyone else affected,

Accepted apport into bionic-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/apport/2.20.9-0ubuntu7.5 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  Some tests are flaky due to timeout

Status in apport package in Ubuntu:
  Fix Released
Status in apport source package in Bionic:
  Fix Committed

Bug description:
  The autopkgtests are sometimes passing, sometimes stuck for more than 2h:
  http://autopkgtest.ubuntu.com/packages/apport/cosmic/amd64.
  It's blocking randomly on different tests.

  All tests that are stucked, implements closing a request via a timeout
  (and then, executing "run"). The bet is that the timeout is short
  enough (1s) so that, when autopkgtests infra is busy, time to execute
  the bash subcommand is taking more than a second, and so "dismissing"
  is ran before execution happens and the whole testsuite hangs.

  There are few instances of setting this timeout function:
  $ grep eout_add_sec test/*
  test/test_ui_gtk.py:        GLib.timeout_add_seconds(1, cont)
  test/test_ui_gtk.py:        GLib.timeout_add_seconds(1, cont)
  test/test_ui_gtk.py:        GLib.timeout_add_seconds(1, cont)
  test/test_ui_gtk.py:        GLib.timeout_add_seconds(1, c)
  test/test_ui_gtk.py:        GLib.timeout_add_seconds(1, c)

  Short term solution could be to increase the timeout. Long term would
  be to eliminate this potential race implementing cancelling
  differently.
