[Bug 1421009] Re: unity8 sometimes hangs on boot

 

I tried reproducing this issue on silo 18 using
address_book_app.tests.test_add_contact.TestAddContact.test_go_to_add_contact.

The test failed on the 10th attempt in the same way as in the logs:
http://people.canonical.com/~tjyrinki/qt5/fail/qtbase_ubuntu5/ap-
2015_03_24-21_48_11-address_book_app-1-018.tests

Watching the test, the address-book-app froze as it was launching,
displaying a frozen spinner on the loading screen. Autopilot then timed
out waiting for the app to launch and reported the introspection
failure.

Subsequent tests then failed with the maliit-server error as reported in
the same logs.

The only crash file reported was: _usr_lib_telepathy_mission-
control-5.32011.crash

Bug description:
  The following gdbus call is failing with a "Error: Timeout was
  reached" message:

  gdbus call --session --dest com.canonical.UnityGreeter --object-path /
  --method org.freedesktop.DBus.Properties.Get
  com.canonical.UnityGreeter IsActive

  This is being seen on krillin devices starting with image 106 from
  ubuntu-touch/devel-proposed. It doesn't happen every time, so far
  today, I've seen it 3 times from about 12 tests. On the most recent
  failure, I grabbed a console and tried repeatedly to run the command
  from the shell, even after 2 hours the timeout was still being
  returned (after about 28 seconds).

  A copy of ~/.cache/upstart/unity8.log is here:
  http://paste.ubuntu.com/10179482/

  I have 3 test cases where the problem was observed:
  http://d-jenkins.ubuntu-ci:8080/job/vivid-boottest-qtchooser/1/console
  http://d-jenkins.ubuntu-ci:8080/job/vivid-boottest-gsettings-ubuntu-touch-schemas/1/console
  http://d-jenkins.ubuntu-ci:8080/job/fjg-boottest/3/console

  In all cases, the test is using adt-run (from autopkgtest) to drive a
  test on the phone device. adt-run uses the above gdbus call to
  determine if the desktop is active. In all the examples, the device
  was freshly flashed.

  Update 2015-03-25: the qtbase dbus update in silo 018 seems to address
  the boot issue, but causes autopilot to have problems seeing an
  application start, randomly
