(* Imply cultural affiliation instead of political, see Political status of Taiwan)



Identity (jedp)




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

      •  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]



Blog posts:




Also check out ask.mozilla.org. As Taras wrote:


 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.


 See http://ask.mozilla.org/question/3/why-use-askmozillaorg/?answer=4#post-id-4 for more info 🙂



Seceng (mmc)



WebAPI (overholt)



Quality Programs


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



MemShrink (njn)



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.



Roundtable


(Comments and questions that arise during the course of the meeting or otherwise do not have a section.)


Fuzzers Love Assertions (jruderman) Please encourage devs to add assertions for invariants that might lead to security problems.

Mailing List Threads


(Threads that are likely to be of interest to engineering from various mailing lists.)



Good Reads


(Links to blog posts, books, videos, etc. that you think will be of interest to others.)

      •  (bug 921571 – Fixed two more crashes in SPS profiler disabling of inline frame profiling. Still seeing a crash when running Octane, but hard to reproduce. Fuzzers recruited to help find reproducible shell cases that break the patch.

      

    •  Garbage Collection

        

      •  (bug 961077 – Stop PersistentRooted publicly deriving from LinkedListElement

Layout (jet/dbaron)


<Read Only>




Media (mreavy)


<Read Only>



    

  •  WebRTC is working through its Orange bugs

      

    •  Investigating a number of does-not-exit bugs in test_*_basicAudio.html/etc

    •  Some tests on B2G Emulator debug are currently disabled; there looks to be a framework issue with e10s when running mochitest-remote tests; we landed some debugs that will help when that framework issue is resolved (if the bug still exists then).

    

  •  WebRTC team will be in MV week of Feb 10

  •  Fix for high-resolution captures (and all captures on some webcams) identified; Motion-JPEG cameras often bend the jpeg spec and omits huffman tables if they use the default.



Necko (dougt/jduell)


    

  •  We are planning to land new HTTP cache code temporarily in m-c to shake out bugs this week

      

    •  contact me if this is bad timing for you

    •  And… it was bad timing, so we’re going to postpone until after the fork.

    



Performance (vladan)


    

  •  bug 959130: Regression in Firefox 25 startup times has been traced to ChromeWorkers taking a long time to initialize (bug 960986) + OS.File.read() taking a long time to read the sessionstore.js file (bug 961665)

  •  Roberto Vitillo compared Firefox’s power usage to other browsers while idling on popular websites: http://ravitillo.wordpress.com/2014/01/21/a-matter-of-energy/

      

    •  bug 962594: Roberto found Firefox is using more power than other browsers while idling on Facebook. He traced it to invisible CSS animations activating the refresh driver.

    •  Can we get someone from layout to look at optimizing how CSS animations trigger the refresh driver?

    

  •  Session store improvements:

      

    •  bug 887780: Don’t save state right after startup when restoring the initial session

    •  bug 956826: Private tabs are saved in the session sometimes

    

  •  bug 961810: A new Telemetry dashboard showing badly performing SQL statements will be ready soon. A rough mockup



Note: Please review your Telemetry probes and remove histograms that are no longer needed, and remember to add expiry dates to any new probes.



Seceng (mmc)


    

  •  CSP:  bug 938652 for case-insensitive matching of CSP directives, bug 960694 for serializing JS CSP objects

  •  STS: bug 861117 Error reporting improvements

  •  Application reputation: bug 928536 in review for verifying signatures of windows binaries



WebAPI (overholt)


    

  •  No updates (work week in SF this week)



Quality Programs


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



MemShrink (njn)


Some large memory consumption improvements to pdf.js have been imported into mozilla-central, involving images and image masks, and there are some more in the pipeline. These can save 10s or even 100s of MBs of memory. If you have had trouble with pdf.js’s memory consumption in the past, please try again and let njn know if you still have problems.



OrangeFactor (ryanvm)


    

  •  Past week’s OrangeFactor: 11.76 (Previous Week: 8.32).

      

    •  Heavily dominated by infra problems causing daily tree closures. ~6 with infra not included.

    

  •  Jim Mathies landed a patch for the mochitest-mc hangs (bug 951120) that appears to have fixed the #1 cause of mochitest shutdown hangs. Will work on getting bugs filed for the remaining instances being hit once the dust settles.

  •  13 intermittent failures fixed in the last week – List – Thanks!.



Stability (kairo/bsmedberg)



Roundtable


(Comments and questions that arise during the course of the meeting or otherwise do not have a section.)



    

  •  cpeterson: I will be hosting an “Introduction to Firefox Beta” workshop in the SF office this Thursday, January 30 at 2:30 PM — 3:00 PM (“SFO 319 Golden Gate Bridge”). My goal is to help some interested-but-intimidated Mozilla staff install and dogfood Firefox Beta. If you would like to help, just let me know. Windows wizards are especially welcome. 🙂



<Read only beyond this point>


Friends of the Tree

Media (mreavy)


<Read Only>



    

  •  TURN TCP is being selected when it shouldn’t be (randomly).  This can hurt call delay.  We’re actively working to fix this ASAP.  Note: TURN TCP is only in 28 & 29

      

    •  Fixed bug 960296 which caused video to freeze and not recover when using TURN TCP.  We’re nominating it for uplift to Aurora (28)

Seceng (mmc)


No updates.



Shumway (mbx)

WebAPI (overholt)


    

  •  No updates



Quality Programs


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



MemShrink (njn)


    

  •  Nathan Froyd reduced the size of 32-bit libxul by ~220KB by packing JSJitInfo structs more carefully. This is the latest in a number of recent optimizations he’s done to static code and data size, which are welcome because that’s an area that doesn’t get much attention.



OrangeFactor (ryanvm)


    

  •  Past week’s OrangeFactor: 8.32 (Previous Week: 11.12).

      

    •  Metro mochitest shutdown timeouts still #1 non-infra issue, progress being made finding cause.

    

  •  Concerns over general slowdown of mochitest-bc test suite. Many recent intermittents have been “fixed” by increasing the timeout for the test, but root problem appears to be tests that normally run in short intervals randomly taking much longer (2-3x, if not more). Some sort of bad GC behavior?

      

    •  Linux debug mochitest-bc now takes 140-150 min to run, similar for OSX 10.6 debug. Debug takes 100+ minutes on all platforms.

    •  Filed bug 962156 for investigating.

    

  •  19 intermittent failures fixed in the last week – List – Thanks!.



Stability (kairo/bsmedberg)


    

  •  Overall numbers look OK, but desktop beta is still higher in crash rates for 27 than for 26, and Nightly is significantly bad (see below).

  •  bug 962141 is JS crash spike starting with 2014-01-17 Nightly builds – overall crash rates are up to 2-3x of what they are usually.

13:59 kbrosnan: re-center mtv camera
14:00 KaiRo: bsmedberg: well, if the regression testing from Alice points in the right direction, we might have a single bug landing that might be it
14:00 lmandel: KaiRo, bsmedberg: stability update today?
14:00 bsmedberg: KaiRo: which bug is this? I don't see data in bug 962141
14:00 firebot: Bug https://bugzilla.mozilla.org/show_bug.cgi?id=962141 nor, --, ---, nobody, NEW, JS crash spike starting with 2014-01-17 Nightly builds
14:01 KaiRo: bsmedberg: see https://bugzilla.mozilla.org/show_bug.cgi?id=961466#c1
14:01 firebot: Bug 961466 cri, --, ---, nobody, NEW, crash in js::GCMarker::processMarkStackTop(js::SliceBudget&) on outlook.com
14:01 KaiRo: I pointed to that bug in the other one
14:01 KaiRo: lmandel: we have something today, yes
14:01 KaiRo: lmandel: bsmedberg will do it
14:02 kbrosnan: not so nice for the tv
14:04 bajaj: elan: https://etherpad.mozilla.org/channel-mtg-agenda
14:04 bajaj: check the mobile section
14:05 blassey: totally breaking the "no questions" rule
14:06 lmandel: blassey: questions are cool for releng
14:06 elan: bajaj: thank you. you're pointing to the crash stats for android?
14:06 robcee: should qualify: *some* browser chrome.
14:06 bajaj: elan: yep
14:06 catlee-mtg: there's a no questions rule?
14:07 mschifer: questions are at the end
14:07 lmandel: catlee-mtg: No questions during team standups
14:07 lmandel: or, as mschifer said, save your questions for the end.
14:07 elan: yes, it looks like we're inching the right direction, now
14:08 mfinkle: robcee, *some* ?
14:08 mschifer: of course, questions asked in irc don't count.
14:08 catlee-mtg: :)
14:09 mfinkle: blassey, http://eideticker.mozilla.org/#/samsung-gn/nytimes-load/timetostableframe
14:09 mfinkle: ~3secs
14:09 robcee: mfinkle: doesn't work for anonymous nodes, i.e., you can't inspect into a <button> element to see the image or text elements.
14:09 mfinkle: robcee, seems sane
14:09 robcee: but works well for lots of high-level xul stuff
14:09 robcee: and we'll get into the xbl components soonish, I think
14:09 blassey: mfinkle: as I said, embarrassing
14:10 blassey: though I think the embarrassment belongs to google, not us
14:10 mfinkle: blassey, i feel some of it

  •  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.

  •  Recent changes of note:

      

    •  Added a pref to completely disable add-on loading (bug 946296).

    •  Disabled automatic desktop<->Metro switching on convertible tablet/laptop hybrid devices (bug 940677).

    •  Windows “Start” tile now launches in the user’s previously-chosen UI, instead of always defaulting to Metro (bug 946990).

    •  Gonk-Kitkat Porting: Prepare the manifest for building image.

    •  Fugu: On-site support.

    



Firefox OS Media Apps (hema)


<Read Only>



    

  •  Bug Investigation and Fixes for some of them: http://tinyurl.com/paqfk6e

  •  Landed targeted media features into 1.3 except for the image orientation gallery feature which will land in the next train

  •  Triaging and Continuing to work on 1.3 bugs that are coming in

  •  Starting requirements grooming and planning for 1.4

  •  Continuing on quality improvements for some of the media apps



Firefox OS Productivity (doliver)


<Read Only>


1.3 status



    

  •  Testing is well underway on our new 1.3 features. Find, fix, repeat.



1.4 status



    

  •  We have reviewed the new targeted features for Clock, Calendar and E-mail

  •  Team is scoping the work this week and we’ll get started on development in the first half of January



Team updates


Lots of changes to report:



    

  •  New team members: The UX group has moved around some assignments and we have four new team members in Taipei who will handle all of our UX needs: Mike Tsai, Neo Hsieh, Harly Hsu and Juwei Huang

  •  Clock app: The Bocoup group have been working on this app for the 1.2 & 1.3 releases and Mike Pennisi at Bocoup is the current module owner. They are coming off the project at the end of January so we are beginning the process to transition the ownership of this app back into our team.

  •  Notes/Notes+ app: Everything.me created these apps for the initial launch of FxOS and published them in the marketplace. They are no longer interested in maintaining the apps so we are also bringing this effort into the Productivity team. The first order of business is to clean up the Evernote integration in the Notes+ app. We have started working on this now with a new contractor on our team.

  •  Backlog management: Like other teams, we have found that trying to manage our backlog in Pivotal Tracker has not been very successful. Trying to keep it in sync with Bugzilla proved to be too much overhead. For 1.4, we’re moving back into bugzilla with a combination of whiteboards and flags to identify our current and future work. The Pivotal Tracker board will be cleaned out and removed.

    • receiving messages via both SIMs

    



There was a small issue with data and this is being worked on and should be ready this week.

We are looking good for the reduced set of features we wanted to land in v1.3. Now onwards and upwards to close DSDS off with v1.4 – plus any bugs raised on v1.3.

  •  Starting with the latest beta, we are successfully reserving memory for Breakpad to use, so more OOM crashes should get minidumps.



Roundtable


(Comments and questions that arise during the course of the meeting or otherwise do not have a section.)



<Read only beyond this point>


Friends of the Tree


There were great changes by volunteers in Core and Toolkit during the past week. Thanks to all of these contributors for their passion and hard work! Here are some highlights:




Mailing List Threads


(Threads that are likely to be of interest to engineering from various mailing lists.)

irc #planning Log From This Meeting


[2:03pm] lmandel: https://wiki.mozilla.org/Platform/2013-12-03
[2:04pm] KaiRo: lmandel: I have a one-sentence update for Stability
[2:04pm] lmandel: KaiRo: OK. Thanks.
[2:06pm] elan: lmandel: I tagged shumway update as read only
[2:06pm] lmandel: elan: k
[2:06pm] elan: if mbx decides to speak to it, that will be a happy surprise
[2:07pm] dveditz: mbrubeck: I noticed that change.... very happy to see it
[2:08pm] lmandel: RyanVM|sheriffduty: Audible today?
[2:08pm] RyanVM|sheriffduty: lmandel: no
[2:09pm] mbrubeck: Jumping on the Browser Toolbox bandwagon, we also have shiny new docs for using remote debugging to debug/inspect Metro Firefox: https://developer.mozilla.org/en-US/docs/Tools/Remote_Debugging/Firefox_for_Metro
[2:10pm] elan: and we need to work on making the shumway update more extensive but this week is a small first step
[2:11pm] catlee: gavin: how many users to we have on holly nihglites?
[2:11pm] catlee: nightlies
[2:11pm] joduinn-mtg: gavin: followup about australis... can you make sure to loop hwine into the convo? he's on the hook for the migration with RelEng
[2:12pm] gavin: joduinn-mtg: will do
[2:12pm] • joduinn-mtg tips hat to gavin
[2:12pm] gavin: catlee: I think you're probably in a better position to tell me? 
[2:12pm] gavin: I don't know
[2:13pm] mbrubeck: gavin, catlee: The nightly-holly channel had 51 ADI yesterday
[2:13pm] dveditz: gavin: is there any UI changes planned for the menus that slide into the customize panel?  I like the Australis look over all, but that slidy menu thing is kinda ugly. Especially where it leaves part of the panel showing on the edge (looks like a mistake)
[2:13pm] mbrubeck: laura: Sorry!  Yes, you just missed the Platform meeting, if that's what you were asking
[2:14pm] laura: no worries, I was absorbed in jcook's presentation
[2:14pm] laura: and only realized the time when he finished
[2:14pm] laura: thanks mbrubeck
[2:14pm] mbrubeck: gavin, catlee: That's an increase of 5000% from last Wednesday, when it had 1 ADI!
[2:15pm] catlee: we'll beat chrome in no time!
[2:15pm] catlee: I'm a bit worried about shipping relatively untested builds to aurora users then
[2:16pm] mschifer: we have been running automation on holly
[2:16pm] gavin: dveditz: not sure what you're referring to - I see https://cloudup.com/c4GoZ7t9egv
[2:16pm] mbrubeck: If we keep growing by 5000% every 5 days, then in another month we will have about 800 billion users on holly
[2:17pm] gavin: dveditz: the "cut off icon on the left" styling is intentional - shows you how to get back to the normal panel
[2:17pm] dveditz: gavin: exactly! notice the buttons half peeking on the left? looks like a mistake
[2:18pm] gavin: it's a spatial orientation kind of thingy
[2:18pm] dveditz: also felt a little odd to press the help button on the left of the panel and have the menu show up on the right
[2:18pm] jesup: I think we missed a new contributor (first patch) in Friends of the Tree: Adrian Cruceru (cruceru.adrian@yahoo.com), bug 876876 which landed 11/22-23.
[2:18pm] firebot: Bug https://bugzilla.mozilla.org/show_bug.cgi?id=876876 cri, --, mozilla28, cruceru.adrian, VERI FIXED, crash in webrtc::videocapturemodule::DeviceInfoDS::GetDeviceInfo
[2:18pm] dveditz: gavin: I get that it's intentional... I'm just saying it doesn't really work for me (one isolated anecdotal data point, from an otherwise Australis fan not a hater) 
[2:19pm] gavin: ok!
[2:19pm] dveditz: just throw it in the bucket of feedback for later
[2:19pm] dveditz: and see if more like it pile up or I'm an outlier
[2:19pm] mbrubeck: Maybe if the "peeking" part on the left were faded somewhat it would look more intentional.
[2:20pm] gavin: shorlander: ^
[2:25pm] mbrubeck: (or dimmed?)
[2:26pm] shorlander: mbrubeck: History in the panel here might be more inline with what you are talking about: http://people.mozilla.org/~shorlander/mockups-interactive/australis-interactive-mockups/windows8.html
[2:26pm] shorlander: gavin, dveditz: thanks!
