Merging m-c into Cedar

We can merge the latest m-c code into cedar to:

• compare latest unittest results + talos numbers between m-c buildbot tests and cedar mozharness tests
• get new cedar builds for testing

To do this:

# Get a copy of cedar
hg clone http://hg.mozilla.org/projects/cedar

cd cedar

# Update to latest, in case someone has updated cedar since you last cloned/updated.
# the hg up -C will blow away any local changes!
hg pull
hg up -C -r default

# Pull latest m-c changes in
hg pull http://hg.mozilla.org/mozilla-central
hg merge
hg commit -m "Merge m-c -> cedar"

# Push to cedar
hg push ssh://hg.mozilla.org/projects/cedar

Results will show up here.

Viewing logs

Jobs will show up on tbpl as they finish.

To view logs

• click on the job on the right
• find "View full log" at the bottom left of the page; click

Known issues are filed against the two tracking bugs:

• bug 713055 - roll out mozharness desktop talos to m-c and project branches
• bug 793022 - roll out mozharness desktop unittests to m-c and project branches

If you find new issues, please file a bug blocking one or both bugs.

Retriggering jobs

• Go to tbpl
• Click on the job in question
• The plus sign in the bottom left will retry the job.

Each of these will pull the latest-and-greatest from mozharness, so if you checked a fix in, you can re-run the broken tests.

Adding additional tests to Cedar

If we want to readd tpaint once bug 794587 is fixed:

• add "tpaint" to the other suite tests here: http://hg.mozilla.org/projects/cedar/file/38215d0638b0/testing/talos/talos.json#l55
• check that into ssh://hg.mozilla.org/projects/cedar
• the resulting build will trigger an "other" talos suite with tpaint.

If we want to add another test type, e.g. marionette, to cedar:

• add "cedar" to the list of marionette branches here: http://hg.mozilla.org/build/buildbot-configs/file/680736f2dc1f/mozilla-tests/config.py#l1076
• move the marionette for loop below the unittest for loop.
  • This is because the unittest for loop zeros out the tests for cedar here.
    • (this is because we don't want to have both buildbot-based and mozharness-based tests running on cedar.)
• get review for your change
• land
• wait for reconfig, or poke buildduty for an expedited reconfig if needed.
