Build Changes (gps)

(Build changes of which engineers should be aware.)

RelEng (catlee)

(Repo, test, and other information for engineers from the release engineering team.)

Upcoming Outages/Upgrades

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

Quality Programs

(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)

OrangeFactor (ryanvm)

  • Past week's OrangeFactor: 4.51 (last week: 4.52).
  • Android and B2G timeouts continue to plague the trees with little to no visible activity in the bugs.
  • The Marionette harness tests were successfully split from the webapi tests on B2G. Do to the ongoing high failure rates of the webapi tests (15-20% last time I checked), it is very likely that they will be hidden by default on Treeherder/TBPL soon.
  • 30 intermittent failures fixed in the last week - List - Thanks!.
    • A special thanks to Nicolas Silva (:nical) for being on a B2G crash fixing streak.
    • Thanks also to Randell Jesup (:jesup) for fixing many of the lingering oranges that were fallout from the MediaStreamGraph refactoring.
    • And thanks to JW Wang (:jwwang) for continuing to fight tirelessly to keep the media tests running green.

CritSmash (dbolter)

MemShrink (njn)

  • DMD has undergone major surgery. It now produces JSON output that describes the heap, and there is a new dmd.py script for post-processing. This new structure makes DMD much more flexible: dmd.py has numerous options to control how the data is analyzed; new heap analyses will be *much* easier to add; and you can do multiple different analyses on a single heap snapshot without having to re-run the browser. Full instructions are here.

Stability (kairo)

  • Overall numbers starting to look decent again.
  • Needs action:
  • FYI:
    • Beta 33 desktop is up ~0.1 crashes / 100 ADI compared to 32 in the same final phase. This is probably just more likeliness of OOM due to OMTC. Still awesome effort in the last few weeks to get us to this state where we're OK to ship that way.
    • Beta 33 for Android is looking very good now.
    • On Nightly 35, a pretty large nsCSSValue crash in bug 1077746 popped up recently but is fixed now
    • Also on Nightly 35, crash reporting was broken with Mac signing v2, but fix has landed for that (bug 1076977).

Team Stand-ups

(In <2 mins, what did your team accomplish last week, on what is your team working on this week, and on what, if anything, is your team blocked? No questions during the stand-ups. All questions should be asked during the roundtable.)
