Sometime on treeherder, jobs get coalesced (a.k.a. we run the tests on the most recent revision) in order to handle load. This is good so we can catch up when many pushes are committed on a tree.

However, when a job run on the most recent code comes back failing we need to find out which revision introduced the the regression. This is when we need to backfill up to the last good run.

In this release of mozci we have added the ability to --backfill:

python scripts/trigger_range.py --buildername "b2g_ubuntu64_vm cedar debug test gaia-js-integration-5" --dry-run --revision 2dea8b3c6c91 --backfill

This should be useful specially for sheriffs.

You can start using mozci as long as you have LDAP credentials. Follow these steps to get started:

git clone https://github.com/armenzg/mozilla_ci_tools.git
python setup.py develop (or install)
