The Need To Know

  • While there were dromaeo failures on talos for the changeset we built our Desktop FF23.0b8 with, we’re going to let it ride since the offending changeset has been backed out, a fix is in, and we have a Thursday Desktop beta
  • We’ll respin the mobile beta for a couple of addons that we want before our final beta next week
    • bug 886576 – Unable to show the dynamic address bar on short Twitter pages

Notices/Schedule (akeybl/lsblakk/bajaj)

48 bugs (52 bugs last week) 36 bugs (48 bugs last week)
Unresolved Aurora 24 Trackers (non-security, not tracked for Beta) Unresolved Beta 23 Trackers (non-security)

Build Changes (gps)

(Build changes of which engineers should be aware.)

Upcoming Outages/Upgrades

(System outages/upgrades and tree closures that impact engineering.)

Key Issues

(Non team specific issues that impact engineering.)

releng (joduinn)
  • birch as b2g-inbound has been great success. Official “b2g-inbound” branch is coming, soon “birch” will revert to being normal twig again. Details in bug 875989 or ask hwine.
  • “integration/fx-team” will get sheriff coverage, landing to mozilla-central. We will monitor this experiment for next few weeks.
    • If you are on fx-team, please land on “fx-team” instead of “mozilla-inbound” unless directed otherwise by sheriffs.
  • Try-repo-reset last week to address performance problems. If you see delays while pushing to try, please let sheriffs or RelEng know (or file a bug!)
