In bug 1239301 we noticed that the fonts on the releng Linux hosts versus the
docker image were slightly different and caused some test failures.
The difference is that on the releng hosts we have anti-aliasing disabled and
many tests (reftests mainly) had adapted for this configuration, hence, failing if enabled.
In this bug we're going to disable anti-aliasing for the desktop-test image in
order to pass the tests.
See the difference between the two pushes:
https://treeherder.mozilla.org/#/jobs?repo=try&group_state=expanded&revision=3c9a54d68c95,1d3078c86e52
We went from failing over 200 tests across jobs to less than 10-20 tests in total.
In the future we will have to consider if we want to fix this configuration.
This change disables reporting of crashes of Ubuntu apps.
This is important to fix as it takes away the focus from running tests and make them time out.
This only applies to TaskCluster Linux64 debug test jobs which are running as tier-2.
On the Buildbot side (bug 1220658) we upgraded to mesa-lts-saucy-9.2.1 and that caused a lot of
test failures accross the board.
In this change we're reverting upgrading to that version and going back to where we were.
This generally makes the approach look more like that for desktop-build. The
major difference is that `bin/test.sh` takes arguments which are passed on to
the mzoharness script (MOZHARNESS_SCRIPT) with the addition of config
arguments (MOZHARNESS_CONFIG)
This also refactors the image generation to not depend on puppetagain, and to
install the latest and greatest mercurial in a verified, repeatable way.
As with centos6-build-upd, the ubuntu1204-test-upd image exists to run
'apt-get upgrade' periodically without regenerating the huge parent image.
