When a push contains backouts, retrieve the tasks which failed in recent pushes (and the manifests which failed in them) from Treeherder, skipping failures classified as intermittent, and select those which are known to the label and group models.

This will help sheriffs, but also the AI test-repair agent, know:

  • if there are failures that are still happening after the backout;
  • if the backout fixed the failures they thought would be fixed.

When a push contains backouts, retrieve the tasks which failed in recent
pushes (and the manifests which failed in them) from Treeherder, skipping
failures classified as intermittent, and select those which are known to
the label and group models.
