Read more about our on-going work here.

GFX (milan)

  • Dealing with B2G regressions. Lifetime problems have been exposed by large changes over the past four months, but are only surfacing recently, and there are no easy fixes, including back outs at this point.

Identity (jedp)

JS (naveed)

Layout (jet/dbaron)

Media (mreavy)

<Read Only>

  • Daala - coding party in MV Sept 30th to Oct 3rd -- if interested, contact Maire (mreavy@mozilla.com)

    • Starting to land Mozilla Telemetry and WebRTC stats API
    • More audio latency and AEC improvements coming, and audio quality tracking
    • Working on CPU overload detection and adaptation

Necko (dougt/jduell)

Performance (vladan)

No update

Seceng (mmc)

WebAPI (overholt)

No update

Quality Programs

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

CritSmash (dbolter)

MemShrink (njn)

  • Justin Lebar is leaving Mozilla.
    • Looking back, nobody has contributed more to MemShrink over the past two years.
    • Looking forward, Justin has been in charge of MemShrink on B2G (e.g. see the etherpad he was maintaining) and knows more about B2G memory consumption than anyone else. With plenty of memory-related problems remaining on B2G, this is a hole that desperately needs filling.

OrangeFactor (ryanvm)

  • Past week's OrangeFactor: 5.34 (Previous Week: 6.99).
  • bug 686828 and "code -20" failures are top remaining issues on Fx24.
    • Bug 686828 needs an owner (see above).
    • smichaud has a libevent patch up for review in bug 884471 that works around code -20 failures, waiting on review. Time running short for uplift to Fx24.
  • *32* intermittent failures fixed in the last week - List - Thanks!.

Stability (kairo/bsmedberg)

  • cross-team workweek was last week: still digesting action items and such, but:
    • Kicking off a "stability support" project to auto-fix stability issues if possible and help users recover if not.
    • Status of "the AMD crasher": David Major has been thrown into the lion's den, and can reproduce this intermittently on a QA computer, but no definitive answers yet.
    • bsmedberg is working on doing better crash and hang collection from B2G builds
    • If you haven't seen the crash-stats API, check it out, see the brownbag video, or ask questions on tools.socorro.
    • gps is working on improving the quality of the crash data sent to FHR
  • gfritzsche is finishing up a patch in bug 853864 which will log and profile IPC messages, and is then going to work on making Java out-of-process again.
