  • Window management: bug 961800 (haida/open sheet) pending, other work WIP. meta bug 902766.
  • System refactor: working on converting everything to constructor function (~8/80 bugs landed). meta bug 912952. next: resolve dependency.
  • Setting refactor: AMD pattern (bug 964180) to be landed this week, next: file bugs on panels for conversion.

  • NFC: no update

GFX (milan)

  • Big features for 1.4, with compressed timeframe.
    • Tiling on B2G.
    • Performance improvements (some in Gaia, Layout, but graphics team is triaging and driving all.)
    • Support for KitKat on an unknown device.
    • Expect less (than usual) responsive graphics team in the next four weeks.

Identity (jedp)

JS (naveed)

Layout (jet/dbaron)

Media (mreavy)

<Read Only>

  • WebRTC/Talkilla work week just ended in MV; more in next week's update
  • Fixed bug with one-way video streams reported by TokBox bug 972097 due to mis-merge; uplifted to Aurora/Beta
  • MediaStream internal redesign underway (padenot, roc, jesup, gcp, etc). Need to deal better with clock-rate mismatches/drift and reduce delay, and should help WebAudio. bug 848954 and https://webrtc.etherpad.mozilla.org/mediastream-refactor
    • Ping padenot/jesup if you want to be involved
  • Bunch of improvements in about:webrtc and stats interface coming soon
  • Lots of WebAudio fixes have been landing recently from karlt and padenot

Necko (dougt/jduell)

Performance (vladan)

Blog posts:

Seceng (mmc)

<Read Only>

  • TLS False Start, a performance optimization for TLS connections, is now enabled in Firefox 28 Beta and later. This optimization is only enabled for sites that use non-RC4 TLS_ECDHE_*/TLS_DHE_* cipher suites and which support the NPN extension. This includes Twitter, Google, and CloudFlare-hosted servers. There is some compatibility risk to this feature, though we believe we have mitigated all of it with the aforementioned restrictions. Please report any compatibility issues in the "Core :: Security: PSM" component ASAP. bug 942729
  • insanity::pkix, the new certificate verification library replacing NSS's certificate verification, landed, pref'd-off (security.use_insanity_verification=false). It is expected to be enabled in a couple of weeks, after OCSP support is added and more testing is done. This was also uplifted to Aurora 29 to make it easier for Certificate Authorities to test it one release before it is enabled. If you don't care about your own HTTPS security and you play with this, please report any issues, particularly compatibility issues, in the "Core :: Security: PSM" component ASAP. bug 878932
  • New certificate verification logic for signed packaged apps, based on insanity::pkix, landed in Nightly 30 and will probably be uplifted to Aurora 29 later this week. This enables (will enable, after some non-cert-related issues are resolved) packaged apps from Mozilla Marketplace to be installed in Desktop Firefox. bug 896620
  • Some cases where we were doing unnecessary OCSP fetching, potentially causing main-thread I/O and other badness, were fixed for Firefox 28 and later. You shouldn't notice anything with these changes, but Firefox is getting faster in this respect. bug 950129, bug 950240.

Shumway (mbx)

WebAPI (overholt)

  • baku landed console API in workers (bug 620935)
  • work continues porting DataStore API from JS to C++
    • in the meantime, Gene Lian is writing a C++ wrapper for the current JS implementation
  • bent is very close to landing PBackground (bug 956218)
    • janv is porting QuotaManager (and improving its API) to PBackground (bug 961049)
  • ehsan working on image resizing API
  • earlier today Harald re-iterated partner requests for some sort of keychain-like functionality on Firefox OS
  • Marcos closing in on final manifest spec issues: http://w3c.github.io/manifest/

Quality Programs

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

CritSmash (dbolter)

  • Additional fuzzing is working well to uncover more issues. Tending/fixing them is appreciated.
  • Mitigation: David Major fixed bug 860254 - Poison memory on free for all small allocations

MemShrink (njn)

  • Michael Wu implemented VolatileBuffer, a new class that lets us use volatile memory on OSes that support it, e.g. ashmem on Android.

OrangeFactor (ryanvm)

Stability (kairo/bsmedberg)
