The ICU update to a recent version (52.1) landed, finally, so the Internationalization API (<code>window.Intl</code>, <code>window.Intl.Collator</code>, etc.) should be riding the trains into release now.  As part of updating, {{source|intl/update-icu.sh}} is now a nearly perfectly replayable system -- every local ICU patch is recorded there.  If you're writing a local patch to ICU, you must add it to this file -- otherwise we're very likely to lose it next time ICU gets updated!
 
** Compiler (JIT)
*** {{bug|959597}} - Landed ARM simulator for JIT code, bug . See mailing list message [[https://lists.mozilla.org/pipermail/dev-tech-js-engine-internals/2014-January/001582.html link]] for more info.
*** {{bug|952891}} -  Can we add a fast path for arrays to ForOfIterator
*** {{bug|951439}} - Fix inlining of re.exec() + improved MToString
** Garbage Collection
*** {{bug|956324}} - Debugger can hold pointers to dead breakpoint handler objects
*** {{bug|963356}} - Explore and mitigate a couple of perf issues with exact rooting.
** Front End and Other
*** Mega. uses asm.js
*** {{bug|963528}} - Don't allocate space for scripts with zero-length data
*** {{bug|952306}} - OdinMonkey: allow module globals to be variable initializers
*** {{bug|960513}} - Landed fix for bug in function relazification

* We're planning to land the new HTTP cache (w/o index) on mozilla-central for a few days this week.  Keep an eye out for bugs.
** don't freak out if your cache gets very large--the code we land doesn't do eviction yet.  Your cache will be cleared when we toggle the pref back.
* HTTP/2 work going well--we're well ahead of Chrome (we've implemented v9, they're at v6). Firefox is the reference HTTP client for most server work at this point

* Past week's OrangeFactor: [http://brasstacks.mozilla.com/orangefactor/ 8.02] (Previous Week: 11.76).
** Infra issues are significantly improved now and many underlying problems have been fixed in the last week. Thanks to everyone involved in that!
** B2G hangs/timeouts ({{bug|948395}}, {{bug|965677}}, {{bug|948895}}) make up 3 of the top 4 oranges being hit on trunk.
** This morning, desktop B2G mochitests and B2G debug emulator mochitsets were hidden on trunk. Unhiding them is tracked in {{bug|967588}} and {{bug|967640}}, respectively.
** The dom-level* tests were disabled on remaining platforms due to ongoing instability. They were disabled on Android in August and OSX in October, with no activity in either of those bugs for fixing and re-enabling them. Fixing and re-enabling them across all platforms is tracked in {{bug|932350}}.
* Thanks to Joel Maher for fixing the frequent OSX and Windows talos hangs we had been hitting.
* 21 intermittent failures fixed in the last week - [https://bugzilla.mozilla.org/buglist.cgi?keywords_type=allwords&keywords=intermittent-failure%2C%20&resolution=FIXED&o1=greaterthan&v1=2014-01-28&f1=cf_last_resolved&query_format=advanced&list_id=9365992 List] - Thanks!.

JS (naveed)

<Read Only>

The ICU update to a recent version (52.1) landed, finally, so the Internationalization API (window.Intl, window.Intl.Collator, etc.) should be riding the trains into release now. As part of updating, intl/update-icu.sh is now a nearly perfectly replayable system -- every local ICU patch is recorded there. If you're writing a local patch to ICU, you must add it to this file -- otherwise we're very likely to lose it next time ICU gets updated!

    • Compiler (JIT)
      • bug 959597 - Landed ARM simulator for JIT code, bug . See mailing list message [link] for more info.
      • bug 952891 - Can we add a fast path for arrays to ForOfIterator
      • bug 951439 - Fix inlining of re.exec() + improved MToString
    • Garbage Collection
      • bug 956324 - Debugger can hold pointers to dead breakpoint handler objects
      • bug 963356 - Explore and mitigate a couple of perf issues with exact rooting.
    • Front End and Other
      • Mega. uses asm.js
      • bug 963528 - Don't allocate space for scripts with zero-length data
      • bug 952306 - OdinMonkey: allow module globals to be variable initializers
      • bug 960513 - Landed fix for bug in function relazification

Layout (jet/dbaron)

<Read Only>

Media (mreavy)

<Read Only>

  • WebRTC and Talkilla teams will both be in MV next week
  • Added support for webcams that use Motion JPEG for higher resolutions (update to libjpeg-turbo that we got upstream to adopt)
  • Update to libyuv (Haswell ASM support, etc) and moving it to media/libyuv for general availability -- bug 880419
  • Fixed major DataChannel Orange-factor regression (bug 892630) from a B2G change (bug 952220)
  • More stats and info being added to "about:webrtc" page (now shows which candidate is being used as well as RTP/RTCP stats)
  • Fixed some leaks when not responding to a getUserMedia() request
  • In WebRTC try to make sure we don't use TURN TCP when UDP works (bug 962371)

Necko (dougt/jduell)

  • We're planning to land the new HTTP cache (w/o index) on mozilla-central for a few days this week. Keep an eye out for bugs.
    • don't freak out if your cache gets very large--the code we land doesn't do eviction yet. Your cache will be cleared when we toggle the pref back.
  • HTTP/2 work going well--we're well ahead of Chrome (we've implemented v9, they're at v6). Firefox is the reference HTTP client for most server work at this point

Performance (vladan)

Telemetry:

  • bug 902587: We now have all main-thread IO being reported to Telemetry
  • Initial version of SlowSQL dashboard is ready. Code at [1], deployed at [2]

A few people noticed that we do not have a nice, searchable knowledge base for Gecko tech. We have places to ask questions such as various newsgroups, irc and places to document things like the wikis. It is hard to search through all of that, so questions get repeated.

Lets give ask.mozilla.org a try. If you see someone asking questions on IRC or newsgroups, please ask them to write the question on ask.m.o and answer it there. If the answer is already documented elsewhere, provide a link in the answer or duplicate it, up to you.

OrangeFactor (ryanvm)

  • Past week's OrangeFactor: 8.02 (Previous Week: 11.76).
    • Infra issues are significantly improved now and many underlying problems have been fixed in the last week. Thanks to everyone involved in that!
    • B2G hangs/timeouts (bug 948395, bug 965677, bug 948895) make up 3 of the top 4 oranges being hit on trunk.
    • This morning, desktop B2G mochitests and B2G debug emulator mochitsets were hidden on trunk. Unhiding them is tracked in bug 967588 and bug 967640, respectively.
    • The dom-level* tests were disabled on remaining platforms due to ongoing instability. They were disabled on Android in August and OSX in October, with no activity in either of those bugs for fixing and re-enabling them. Fixing and re-enabling them across all platforms is tracked in bug 932350.
  • Thanks to Joel Maher for fixing the frequent OSX and Windows talos hangs we had been hitting.
  • 21 intermittent failures fixed in the last week - List - Thanks!.

Stability (kairo/bsmedberg)

  • Overall numbers for outgoing releases/versions look fine, we're waiting on data for new ones, to come later this and early next week.
