Build Changes (gps)
(Build changes of which engineers should be aware.)
(Repo, test, and other information for engineers from the release engineering team.)
(System outages/upgrades and tree closures that impact engineering.)
- Tree Closing Window Saturday, Dec 20. Tentative time 0900-1730 PT, see tracker for details.
(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)
- Past week's OrangeFactor: 2.29 (last week: 3.16).
- Many of the top oranges are lacking in action. I'll be pinging in bugs soon, please help if you can.
- 15 intermittent failures marked as fixed in the last week - List - Thanks!.
- Thanks to Andreas Pehrson from Telenor for fixing a frequent B2G assertion orange.
DMD now does cumulative heap profiling. This is great for finding places where excessive numbers of short-lived heap allocations occur.
- Numbers look bad on desktop to some degree due to https://bugzilla.mozilla.org/show_bug.cgi?id=1097321#c26 (75% of all 35.0b3 crashes!)
(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.)
- All of this was announced in dev.platform and dev.b2g but here's your chance to ask questions
- PSA: You can now look your Try pushes to your custom mozharness repository (e.g. a user repo)
- Old news: You can easily run mozharness jobs on your machine (more support coming)
B2G Services (dougt)
Cloud Services (mmayo)
Desktop Platform (bsmedberg)
Developer Services (gps/lthomson)
Developer Tools (prouget)
- We're disabling WebSocket on Workers on beta because it's not stable enough.
Electrolysis (e10s) (blassey)
- Please help test e10s in Nightly!
- Known issues: https://wiki.mozilla.org/Electrolysis#What_to_Expect

Ok, thanks 11:13 AM <jduell> jesup: hmm, this looks interesting... http://mxr.mozilla.org/mozilla-central/source/gfx/thebes/gfxAndroidPlatform.cpp#117
