    • B2G debug emulator related
    • Shutdown sequence for graphics ipdl
  • OMTC desktop
    • Accelerated windows in progress, looking at which performance issues can be remedied. Aiming to enable early in 32.

Identity (jedp)

<Read Only>

  • Fx Accounts on FxOS: First QA pass finds we fulfill committed user stories
  • Sync on Desktop: Please keep testing

JS (naveed)

<Read Only>

  • Garbage Collection
    • Continue stomping out remaing GGC crashes. More aggressive diagnostics added to Nightly.
  • Front End and Other
    • bug 995200: Enable strict mode for self-hosted code in opt builds, too
    • bug 911147: Implement ES6 Array.prototype.fill

Layout (jet/dbaron)

<Read Only>

  • Testing: reftest is now testing invalidation rects properly again bug 995410

  • Platform parity of Web features: @font-face { src:local(...) } now supported on Android bug 769194

Media (mreavy)

  • Landed major update of AEC we'd been expecting. AEC is now run on getUserMedia streams directly.
    • Was bounced twice and took a week to land due to b2g emulator issues (see m.d.platform)
  • Found that the fix for delays opening audio streams on Mac (bug 919215) didn't solve that cubeb_init could take hundreds of ms or even >8 seconds, leading to permanent delay/echo on Macs, especially using speakerphone modes. Fixed.
  • MediaStreamGraph now resamples and mixes to the "preferred" output rate (typically 44100 or 48000) before passing audio to AudioStream.
  • Even moving some tests around from one dir to another broke B2G opt emulator (bug 963244 went perma-orange until the move was reverted)

Necko (dougt/jduell)

  • no update this week

Performance (vladan/avih)

  • IOInterposer non blocking observers - less interruptions for normal browsing when collecting IO data (nightly).
  • Reduced addons compatibility checks - most tests now pass.
  • Still fixing maintrhead IO bugs.
  • Still working on talos profiling. Phase one is likely to not support windows.
  • Improved telemetry dashboard: more analytics integration, slowSQL bugfix, jobs timeout notifications.
  • Handling talos regressions (bug 990644) - process hopefully in place, impact unclear.

Seceng (grobinson)

  • We're working on an addon to help users protect themselves and learn more about Heartbleed. WIP on Github

Shumway (mbx)

WebAPI (overholt)

  • Tobie Langel started on a contract today to help advance our Service Workers implementation
    • speaking of Service Workers, the cache API design is coming along and the necko team is getting involved

10:56 KaiRo: cpeterson: no stability audible today
10:56 cpeterson: KaiRo: ok
11:01 RyanVM|sheriffduty: mreavy: safe to say that the "right" media people aren't here for me to rant about the current state of the media mochitests? (not webrtc stuff)
11:01 RyanVM|sheriffduty: i.e. bug 994877
11:02 RyanVM|sheriffduty: I think I counted 6-7 bugs in the top 20 OF

11:02 RyanVM|sheriffduty: great
11:02 Waldo: woo taxes /o\

11:12 davidb: (i use nightly)
11:13 mreavy: davidb: soon it will be Loop, which will be landing in the next week or so.  In the meantime is what I recommend.  For example, will give you a "room".  You can share that link with whoever you want to have a call with.
11:14 dveditz: unofficial Heartbleed addon:
11:14 dveditz: seceng is working on a better one though

11:20 davidb: ok great
11:20 davidb: i was wondering if one was better than the other

11:21 mreavy: davidb: ^^
11:21 davidb: ty
11:23 KaiRo: realizes he potentially should have put the Mac Flash crashes into the agenda, given how many people at Mozilla use Macs
