Bug Triage

Regression Engineering Owner (REO)

Every release has an assigned Regression Engineering Owner (formerly known as "Engineering Release Boss") whose responsibilities include:

  • be a partner for release management's Release Manager assigned to the same release
  • ensure a decision is made about each regression reported in the release
    • push for the responsible team to fix it
    • back related changes out
    • ship with it
    • delay shipping
  • keep a mental state of how we are doing with regressions in a release
  • pay close attention to release-drivers mailing list
  • run the weekly regression triage meeting

Weekly Regression Triage Meeting

Asynchronous Regression Tracking

  • Engineering managers and component owners keep track of regressions, especially the new ones. They look through the list for bugs in their components and set the tracking flags for a particular release to reflect their plans for the bug, leaving an explanation in the bug when the status is changed:
    • affected: this regression should be fixed in this particular release (it must be assigned);
    • wontfix: we will not take a fix for this regression in this particular release;
    • fix-optional: we will take a fix if one appears, but otherwise it will go unfixed in this release;
    •  ?: we should talk about this bug in triage

Crash Bug Triage

  • 1-10 position in release: needs an owner, tracking release, needs a fix
  • 11-30 position in release: needinfo component owner looking for an owner to investigate
  • 31-50 position in release: case-by-case, mostly fix-optional
  • Above 50: mark as fix-optional
  • Check for exploitability - you may want to file the bug as security sensitive

Bug Lists

Note: for non-recent regressions (let's say, more than 5 releases old) rather than remove the `regression` keyword please set the status to `fix-optional` across the board. This will remove it from the Regression triage radar, but still allow the bug to be tracked by others as a regression.
