Release Duty

  • FF 46 cycle: kmoir



Firefox 46.0.b9 (kmoir/rail)

Fennec 45.0.2 (nthomas/kmoir)

Firefox-46.0b10 (rail/kmoir)

Firefox 45.0.2 (kmoir/rail/nthomas)

  • build1 - Firefox partner repacks broken, filed bug 1263082. Repacks being broken are due to a bad (new version) of git being deployed on our build machines. I reran the repacks for all platforms from the command line by hand.
  • had to run checksums, final verification jobs manually due to repack failure
  • because the checksums job ran after the push to mirrors job, the checksums jobs are missing. I tried to copy it manually but it didn't work. Turns out it works with boto, not with s3cmd. bug 1263831

Firefox 45.0.2esr (nthomas/kmoir)

  • build 1 - all update verify jobs failed because we built off GECKO4501esr_2016031618_RELBRANCH and bug 1255245 part 2 was only landed on default. The update files had the firefox-mozilla-release tag on them and 45.0.1 expected firefox-mozilla-esr, so the updater refused the updates. Landed on part 2 fix the relbranch,
  • build2 - many repack failures win64 4 and 6, win32 3 and 7(submitting to balrog).
  • build2 - many update verify jobs failed see bug 1263721
  • build3 - was needed because some patches did not land on the relbranch
  • build3 - win64 repack 8/10 had a hang in make upload, reran. 3x mac repacks took 5+ hours to fail when mac-v2-signing7 was overloaded, reran. Many update verify failures.
  • build 3 - after release added win64 bouncer config (bug 1264102. This is more fallout from using a relbranch as bug 1254784 hadn't landed there



Thunderbird 45.0 (nthomas/kmoir)

  • * win32 build step failed for Thunderbird 45.0 build1, bash crashed during the generation of a partial update, which is an intermittent issue. Rerunning the job. nthomas reran
  • release-comm-esr45-win32_repack_8/10 hit a crash in bash while creating an update, reran.
  • release-comm-esr45-win32_repack_8/10 and 5/10 hit a hang while creating an update, reran both.
  • lots or retries on windows repacks, as slaves disconnected from masters
  • repack_5/10 failed for Thunderbird 45.0 build1 on win32 failed many times with bash error, rerunning now
  • release-comm-esr45-thunderbird_antivirus failed connecting to s3. Maybe we should add a retry there? Will have to go look at code.

Second run of this job succeeded.

  • release updates failed because patcher config was missing, hg cp mozEsr38-thunderbird-branch-patcher2.cfg mozEsr45-thunderbird-branch-patcher2.cfg in tools and reran job. Then it failed submitting to balrog because of missing rules. Fixed in bug 1263279 When I ran the job again it failed since the it couldn't commit configs with the same tag, will have to run balrog job manually and retrigger downstream jobs.
  • I changed the cdntest rule (id 334) to remove the (Version: >45.0) restriction and set the rate to 10 as per bug bug 1263279
  • ran checksums and antivirus builders by hand since upstream jobs had failed
  • final verification failed. When the version bump part of the release updates job ran

It didn't update the update configs, only the patcher configs. Looking at the log for ff esr45 it appears the job changes update configs too.

4:55 PM <rail> with tools and buildbot-config cloned in the $PWD
4:55 PM <kmoir> okay
4:56 PM <rail> repeat it for linux/linux64/win32 (need to change the cmd in 2 places) and you are done
4:56 PM <rail> you will need to commit and tag it with the something_RUNTIME tag


  • notes from nthomas: where possible we should look for the 'ready for release' email to come in before shipping. GTK3 gets in the way of that by breaking update verify, but for ESR45 we could remove the ESR38 and older stuff until 45.2 comes along. Not sure there's a good way of handling partner_repack failures
