A-Team (jgriffin)

• Gaia-integration
  • Moved to use static copies of npm modules - https://bugzilla.mozilla.org/show_bug.cgi?id=976251
  • Enabling tests on OSX to see if frequent hangs we see on linux are OS-specific - https://bugzilla.mozilla.org/show_bug.cgi?id=976822
• Gaia-ui-tests
  • Hidden on linux due to frequent hangs, but running on OSX, so not a big problem wrt coverage
  • Could this be infra?
  •  :jgriffin to investigate this further based on discussion with releng

RelEng (aki, armenzg, catlee)

Tracking wiki page: https://wiki.mozilla.org/User:Asasaki:B2GBuilds

• Outcome from downtime on Saturday
  • "Rearrange product delivery mounts to remove nested client-side mounts"
  • https://bugzil.la/971684
  • gcox completed his worked with no problems
    • Bigger stoarge room for B2G Pvt builds
• Keep 12 weeks' worth of builds to allow better regression finding
  • https://bugzil.la/969767
    • AI : QA to follow-up on this
  • nthomas updated the b2g cronjobs to keep the builds around
  • anyone got anything left before we close the bug?
  • a follow up bug was filed for the work after the merge day
• Outcome from Friday's postmortem
  • releng could have communicated better and detect earlier the root clause of the failures
  • releng could have paid more attention to the flaky tests
  • Releng is going to be more vocal for this kind of changes and will be sending announcements to dev-platform and b2g-dev newsgroups. Optionally, we can also announce the changes on the platform and b2g meetings.
    • +1
  • QA will pay more attention to flaky tests.
    • Geo: I'll bring up the issue in the platform testing meeting
• changes are documented at https://wiki.mozilla.org/ReleaseEngineering:Maintenance
• more "jacuzzis"
  • https://bugzilla.mozilla.org/show_bug.cgi?id=970738
  • good-read: http://hearsum.ca/blog/status-update-on-smaller-pools-of-build-machines
  • this change allows us to have a smaller size pool of machines for a given build type
  • this allows for the objdir of those machines to be more recent and have faster builds
  • enabled for these builds http://jacuzzi-allocator.pub.build.mozilla.org/v1/builders/ has a list
  • we've already seen some dep builds as quick as 20min, where they used to be 2 hours or more
    • cool !
• We enabled on Friday the multimedia b2g mochitests for emulator-jb on Cedar
  • https://bugzil.la/973063
  • This will allow ahal to get them working

Support [ralphdaub; rdaub@mozilla.com]

• General Question - Is there a goto place with information on launch countries with dates and devices + versions?
  • ffos-tam@mozilla.com should be the best people to get this answer
  • bajaj to check and get the intranet page
• Contributors in pt-BR discussion forums were able to install ClockWorkMod Recovery on Alcatel OTF (Many thanks to Anderson, Diego Victor, and Marco Aurélio):
  • https://support.mozilla.org/pt-BR/forums/firefox-os-portuguese-forum/710009?last=57762
  • I will be attempting this and creating a video of the process.
