Layout (jet/dbaron)

Media (mreavy)

No updates

Necko (dougt/jduell)

  • HTTP/2:
    • we should be landing draft-8 this week. Working on draft 9 implementation
      • httpd.js is also up to draft 8/9 so we've got test coverage.
      • Akamai may also use our implementation for testing.
    • completed DNS experiment to see if SRV records usable to detect if http:// targets can speak HTTP/2: results seem promising.
  • New HTTP cache. Still on schedule for mid-february m-c landing.
    • Crash-recoverable cache index has landed on gum branch. Needs debugging.
    • Patches in progress for last major feature: eviction.

Performance (vladan)

Seceng (grobinson)

  • Landed bug 713980: Logging blocked cross-site requests to the Web Console. This was a long-standing bug with a lot of requests for completion from web devs.
  • Landed bug 951895: fixes the SpecialPowers message manager in the B2G test harness. If you have tests that are broken/disabled on B2G (testing/mochitest/b2g.json) that use the Message Manager in some way, they might work now...

Shumway (mbx)

No update this week.

WebAPI (overholt)

  • console object coming soon to workers (bug 620935) (baku)
  • postMessage to targetOrigin (bug 949488) (baku)

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)

B2G now has system-wide memory reporting. This is intended to supplant top, ps, procrank, and all the other ways of getting OS-level memory measurements. Please file bugs if you have ideas for extra stuff it should measure.

Paul Adenot fixed a terrible web audio memory leak.

OrangeFactor (ryanvm)

  • Past week's OrangeFactor: 7.51 (Previous Week: 7.74).
  • 10 intermittent failures fixed in the last week - List - Thanks!.

Stability (kairo/bsmedberg)

  • Overall numbers are OK, but tendencies for 27 beta and for 26 on Android point in the wrong direction (while 26 desktop shows improvements). We hope to have a few fixes in 27 beta 4, but we need to work on improvements for Android in the longer run. KaiRo is emailing Android stakeholders on that.
  • On Firefox OS, we found that some phones were released (again) with crash reporting disabled, we also need to follow up on that.
