[Bug 1780767] Re: Some tests are flaky due to timeout

[Launchpad Bug Tracker]

This bug was fixed in the package apport - 2.20.9-0ubuntu7.5

---------------
apport (2.20.9-0ubuntu7.5) bionic; urgency=medium

  * apport/ui.py: when using ubuntu-bug properly handle executables which
    start with /snap/bin. (LP: #1760220)
  * test/test_ui_gtk.py: Increase the timeout so that when the autopkgtest
    infrastructure is busy the tests should not fail. (LP: #1780767)

Title:
  Some tests are flaky due to timeout

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

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.
