    • ARM raytrace regression fixed - bug
    • JS h264 decoder memory utlization bug fixed
    • Exact rooting fuzz bugs
    • Started ES6 self-hosted Arrays extras
    • Work on getting --ion-eager switch in the browser for fuzzers.
    • Landed in inbound a script to import selected subsets (ch06/, intl402/) of ECMAScript's test262 suite, those tests to run every push; landed those subsets in inbound.
    • Closed (bug 831507 ) - Adding GGC post-write barriers to baseline compiler code generation.
    • Put more work on a well-commented pseudo-implementation of ES6 module loaders. You can see it here: https://people.mozilla.com/~jorendorff/js-loaders/loaders.html

    • Increase FFI asm.js calls
    • Static rooting analysis precision improvements
    • Green GGC on tbpl
    • Implement proxy invoke trap (bug 878605 )
    • Removing unneeded #includes in SpiderMonkey in the hope of speeding up compile times (bug https://bugzilla.mozilla.org/show_bug.cgi?id=634839).
    • clean-up memory pressure patches. (bug 876029 ) & (bug 869263 )
    • find regression on Sunspider (between May 21st to 29th)
    • Bug 878992 - Remove unused TypeObject flag OBJECT_FLAG_UNINLINEABLE which was only relevant for now-defunct JM.

Layout (jet/dbaron)

  • (two weeks ago) we met, with Graphics and Media, in Taipei
  • a bunch of the team (dbaron, fantasai, jet, jdaggett, SimonSapin, heycam) at SVG and CSS Working Group meetings this week
  • off main thread animations finally has some test coverage, or will very soon (bug 788549), which is a step towards enabling it on non-B2G platforms
  • zoom-in and zoom-out values of CSS cursor property now unprefixed (bug 772153)
  • major ongoing projects:
    • making CSS Flexbox paginate correctly (so pages using it will print) (bug 811024)
    • starting to investigate implementing overflow:fragments (bug 874238)

Media (mreavy)

  • WebRTC's first implementation will be going out in Fx 22 Desktop. We believe all release blockers have been eliminated in Beta 4.
    • The patch for Bug 866514 was backed out of Beta because it introduced bug 870002. However, it now appears the new windows ix test hardware has made the errors disappear... perhaps it was "too much garbage without GC". Any help/analysis is appreciated.
    • Actively looking at Bug 879213 - occasional audio-only latency issue, where audio noticeably lags video (it may be more common in certain network situations or environments). We believe it affects all products (desktop and mobile).
    • TURN support (http://tools.ietf.org/html/rfc5766) is coming in Fx 23.
  • Working with the team in Taipei to get WebRTC working on B2G
  • WebRTC's work week is next week in Sunnyvale (10 mins from the MV office)
  • Ben Brittain is the new intern for WebRTC. He is working on hooking up WebRTC to telemetry
  • Made good progress on improving H.264/MP4 playback performance on Win 7/8. There are 2 known bugs related to H.264/MP4 playback:
    • Bug 875644 - HE-AAC doesn't work properly (HE-AAC is not very common yet on the web)
    • Bug 879099 - Minor regression with color saturation on Nvidia
  • Close to finishing gstreamer backend for Linux to enable H.264 playback, but B2G work is taking priority this week
  • On track to deliver the first part of MSE (Media Source Extensions) by end of the month (i.e. a first phase of adaptive streaming [chunked multi-bitrate/resolution streaming] support that enables DASH-JS)
  • roc: Fixed a few video controls bugs affecting YouTube last week. People are now working on a few different video playback issues with the Youtube app, hoping to have them fixed this week.

  • Update on Disk Cache rewrite (jduell)
  • ODA off main thread (sworkman)
  • Http2, for real (patrick)

  • Aaron Klotz is working on a patch to report main-thread NSPR & SQLite I/O to the profiler (bug 867762)
  • Irving and Felipe are re-factoring the Addon Manager to store configuration in JSON files instead of SQLite DBs + move I/O operations off the main thread (bug 853388 + bug 853389).
