Mergeduty

Mergeduty is responsible for performing branching + code uplifts, and making sure the automation is ready for those branches and merges. The steps that need to be performed alternate; we're basing this on whether mozilla-central will become an odd or even numbered Gecko version after Merge Day. (See: What train is it now? and RapidRelease/Calendar)

Note that there are several uplifts involved:

  • beta->release
  • aurora->beta
  • central->aurora
  • aurora->b2gXX_vX_X

Current process

Two weeks before

  • Read these docs. Please do your part to familiarize yourself with what needs doing.
  • Prepare the patch for the mozilla-release bump in buildbot-configs
  • Look at blocking bugs against the merge day bugs, and ask around if there are any patches that need to land with the release migration
  • Prepare the other patches for Release Merge Day

Release Merge Day

One week before

Release Merge Day + the release build will take up the first portion of this week.

  • Prepare the patch for the other desktop train migrations
  • Look at blocking bugs against the merge day bugs, and ask around if there are any patches that need to land with the other migrations
  • Prep the other patches for Merge Day (next section). Merge Day will be Very Busy, so the patches+reviews beforehand will be very important.
  • run the b2g_tag script with --pull to clone the repos ahead of time.
