Release Duty

  • FF 44 cycle: jlund/rail (mtabara shadowing)
  • FF 45 cycle: mtabara


  • Firefox_44.0b3 and Firefox_44.0b5 skipped for holiday reasons
  • there will be NO "What's New Page" for FF 44 release


Firefox 43.0.4 (jlund/rail/mtabara)

  • "Because of a high volume crash on Windows on 43.0.3 we disabled updates to 43.0.3 and are about to build, test, and I hope release 43.0.4"
  • Several failures along the way
    • build1: failed at repack_9/10 on win32 - timed out during cloning stuff, rerunning
    • build1: abandoned, starting build2 with "Backed out gdata patch, added sha-1 deprecation pref flip"
    • build2: abandoned as well. release automation pushed artifacts to build1 url location instead of build2
    • build2: there was an automation race condition where our masters tried pulling from and did not get served a recent push that included an incremental buildnum bump from 1 -> 2. This was likely due to the hg.m.o vcsreplicator issues that happened today and overlapped with the release and reconfig.
    • build2: we had an infrastructure failure with build2. Added a small ridealong patch to support download directories on multi-user machines
    • build3: started, in progress
    • build3: failed at firefox_antivirus, re-triggered; also failed in 4 out of 6 update_verify_release steps on win64, all retriggered

Firefox/Fennec_44.0b6 (jlund/rail)

  • post-release step still undone for Fennec 44.0b6. still pending QE signoff?
  • dragged from last week, had to run the post-release step after QE sign-off
  • No failures of any type, some intermittent stuff:
    • failed at repack_9/10 on win64, automatic retry
    • all of the update verify linux failures were gtk related, hence ignored

Thunderbird 38.5.1 (jlund/rail/mtabara)

  • watershed release, has part2 patch
  • release notes here
  • last status from 2015: release-localtest channel looks good, awaiting request for release-cdntest. It's being hold off until the various upgrade paths using the waterfall are fully tested.
  • Some intermittent failures came up:
    • build1 - bug 1235071 ssh: no address associated with name, invalid bug - wrong cset
    • build2 - bug 1226276 l10n taggging fails when running 'hg branches' against clean checkout of certain locale repos, rerunning

Firefox/Fennec_44.0b7 (jlund/mtabara/rail)

  • No failures of any type, some intermittent stuff:
    • failed in some repacks, automatic retry
    • run failed, update status was not successful, retriggered
    • could not download source firefox-44.0b7.tar.bz2, download_builds returned non-zero, retriggered
