DOM (jst/overholt)

  • WebIDL bindings infrastructure now largely done. 2 1/2 years in the making, lots of details to get right in lots of corners. Big shout out to the team who worked on this, including peterv, bz, khuey, bholley, mccr8, and efaust. Also a big shout out to the numerous people who helped convert code from using XPConnect to WebIDL, including dz, Ms2ger, ehsan, baku, bjacob, tbsaunde, and many many more (too many to name here).

irc #planning Log From This Meeting

dveditz: blassey: why "janus"?
blassey: roman god of time, space and safe passage
blassey: why the change? apparently Speedy Gonzales is not considered to be culturally sensitive
...
Mossop: Some webapps use [HTTP requests waiting longer than 5 minutes] as a push notification. Make an XHR request to your server, when it wants to tell the client something it responds

Need To Know

(Release and system issues that may impact engineering this week.)

Notices/Schedule (lsblakk/sylvestre)

Next Merge: July 21, 2014 Next Release: July 22, 2014
Trains
Central: 33 Aurora: 32 Beta: 31 Release: 30

Build Changes (gps)

(Build changes of which engineers should be aware.)

RelEng (catlee)

(Repo, test, and other information for engineers from the release engineering team.)

  • Unified builds now enabled for B2G device builds bug 950676

Upcoming Outages/Upgrades

(System outages/upgrades and tree closures that impact engineering.)

Quality Programs

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

OrangeFactor (ryanvm)

  • Past week’s OrangeFactor: 7.36 (Previous Week: 9.66).
  • #4: bug 1016310 – Intermittent browser_console_optimized_out_vars.js | Test timed out.
  • Tracking down a ~2x regression in B2G reftest runtime between Gecko 30 and Gecko 32 (bug 1025961).
  • 20 intermittent failures fixed in the last week – List – Thanks!.
    • Thanks to Randell Jesup for fixing various WebRTC crashes and Gijs Kruitbosch for fixing a couple frequent Australis oranges.

MemShrink (njn)

  • Some more big memory usage improvements landed in pdf.js.
  • Jed Davis wrote some patches for profiling the copy-on-write behavior of Nuwa. Unsurprisingly most of the page faults occur when we finish loading JS after forking.

Stability (kairo/bsmedberg)

  • Signatures for OOM crashes are now either “OOM | small” (<256k), “OOM | large | foo” (needs fallible allocation), or “OOM | unknown | foo” (needs OOMAllocationSize annotation). See dev-platform/firefox-dev post from bsmedberg for more details.
  • arewestableyet dashboard now shows more realistic green/yellow/red coding based on experiences of recent release trains.
  • Desktop Beta 31 has bug 988549 (_VEC_memzero | _VEC_memzero, startup) being >9% of all crashes, we will needs GFX team to investigate even though we do not have STR at this time. QA is trying to get as much data as possible out of crash-stats to help, but we will need devs on it.
  • Release suffers from 3rd-party crashes with adware and banking plugins, see recent CrashKill meeting agenda for details on that and other issues causing high crash rates right now.
  • Switch to more reliable ADI infrastructure is coming near, tracked by bug 981663.

Team Stand-ups

(In <2 mins, what did your team accomplish last week, on what is your team working on this week, and on what, if anything, is your team blocked? No questions during the stand-ups. All questions should be asked during the roundtable.)

DOM (jst/overholt)

  • Jon Morton (DOM intern) is picking up the work done last year by Morris Tseng on WebGL in Workers bug 709490
  • Landed patches to feed the HTML parser without going through the main thread for non-HTTP channels (especially relevant to b2g) bug 1024388

GFX (milan)

  • OMTC on Windows is still enabled on Aurora, and we know there are regressions, especially when it comes to WebGL. There is enough real world benefit (e.g., async video) to make disabling OMTC on Aurora a difficult decision. Stay tuned.
  • With the layout team working on CSSOM-View scroll-behavior 1010538, we’re coordinating with them and UX when it comes to APZ, etc.
  • Low resolution tiling for B2G is on trunk/aurora, we have some correctness regressions, some of them in Fennec.
  • Accelerated (flywheel) scrolling created more checkerboarding opportunities, as the far content is requested sooner.
  • Good conversations about tiling+apz on desktop between graphics and layout teams. No hard dates yet, but things are moving in the right direction.
  • There is this thing that was too slow on Firefox OS 1.4, and is now fast enough, and that’s a big deal and everybody is really excited.

Media (mreavy)

<Read Only>

  • about:webrtc now has buttons to enable internal webrtc.org logging, and to enable AEC input/outout dumps to files.
    • There are prefs to set the destinations, with platform-appropriate defaults (media.webrtc.debug.*)
    • You can now turn on webrtc.org logging (formerly only available via NSPR_LOG_MODULES=webrtc_trace:NNNN) in about:config
    • Identified some-macs-only echo issue with (analog) headsets, where there’s a 1-second non-airpath (non-acoustic) echo coming from somewhere in the OS/system.
  • Load Manager for webrtc is now on by default, and there’s a known regression when it reduces send resolution that causes horizontal artifacts.
  • We expect to move the webrtc and other media tests on b2g emulator to ix hardware slaves (from AWS) to try to rein in performance-induced oranges. We expect this in the next week or so.
  • Lots of work fixing holes and timing issues in the ICE/etc code, both for Loop/field issues and also trying to tamp down all the “ICE failed to connect”/etc oranges especially on B2G emulator (see previous note as well).

Necko (dougt/jduell)

  • Ten year old bug finally fixed: Download manager couldn’t detect incomplete downloads (bug 237623)
    • We now fail partial transfers with a new error (NS_ERROR_NET_PARTIAL_TRANSFER): possible we’ve missed some code that needs to handle/ignore it to work as it did before. (we fixed imglib and some other call sites).

Performance (vladan)

  • bug 998863: Aaron Klotz has a prototype of a patch to asynchronously initialize plugins (e.g. Flash) in web pages. This will mitigate 4 out of the top 10 most common sources of long Firefox janks!

  • bug 1017055, bug 1019101, bug 1019611: We’re looking into pausing GC and CC during UI animations. The first step is to collect Telemetry to determine how much of a benefit we could gain from this.
  • bug 1020663: Avi Halachmi is adding WebGL performance tests to Talos.
  • bug 946567: We’re aware of many Talos regressions from turning OMTC on by default on Windows. Gfx team is working on fixing these

irc #planning Log From This Meeting

11:01 cpeterson: today's engineering meeting notes: https://wiki.mozilla.org/Platform/2014-06-10
11:01 KaiRo: cpeterson: no stability voice update today
11:01 cpeterson: ok
11:06 jesup: OMTC has caused me to have to set gfx.direct2d.disabled=true on WIN32 Lenovo W520 (otherwise all black; bad for browsing)
11:10 catlee: what does MSE mean?
11:11 KaiRo: ++ for looking at OOM
11:11 kip: MSE = Media Source Extensions: https://wiki.mozilla.org/Platform/MediaSourceExtensions
11:11 dholbert: not EME
11:12 dholbert: best use-case for MSE I've heard is that MSE lets you dynamically swap between high-quality & low-quality streams, as you play a video
11:12 jesup: #memshrink for memory work!
11:13 jesup: and http://areweslimyet.com IIRC
11:13 KaiRo: Win64 is not solving OOM completely, 1/3 to 1/2 of our OOM issues are running out of physical memory, which win64 cannot fix (actually will probably make worse where it's used)
11:14 cpeterson: KaiRo: thanks, I didn't know that.
11:15 cpeterson: KaiRo: do you know if there are specific efforts to address physical memory OOM (beyond our normal MemShrink work)?
11:15 KaiRo: cpeterson: also, the out-of-VM issues are probably helped a ton by e10s anyhow, even without 64bit
11:15 KaiRo: cpeterson: bsmedberg is looking into the OOM area more closely with his team, you'd need to ask him
11:15 cpeterson: ok
11:16 KaiRo: cpeterson: I know that one jemalloc patch is close to landing that should makes us deal even somewhat better with fragmentation, which also could help there

10:58 KaiRo: cpeterson: no voice update from stability today
10:58 cpeterson: KaiRo: ok, thanks
11:03 KaiRo: heh, there's an old video that's already ready to watch on airmo instead of a live stream
11:04 davidb: robot ryan
11:04 lmandel: davidb: I think C3PO's voice processor would be an upgrade for Ryan.
11:04 robcee: he's just a protocol droid.
11:05 davidb: useful nonetheless
11:08 jesup: blassey: serious voiping... try turning off AEC when on headset - not guaranteed, but I've seen that many times before with vidyo (less in the last year though)
11:09 jib: Here's the right link https://air.mozilla.org/engineering-meeting-20140527/
11:09 blassey: jesup: thanks
11:09 blassey: vidyo really insists on turning those back on unfortunitely
11:09 overholt: cpeterson, I should have marked the WebAPI section as read-only
11:10 jesup: yeah; I think they changed that.  Also, OS media processing "enhancements" (like on win7/etc) can mess up an AEC
11:10 jesup: Takes digging to turn off

Media (mreavy)

<Read Only>

  • WebRTC Interim meeting in Washington DC this week
  • H264 SDP and packetization code progressing; likely will land soon in support of B2G HW codecs and OpenH264
  • Investigating a significant regression in call connections in WebRTC (possible ICE rate-limiting issue)
    • If confirmed, will ask for uplift of a fix to Beta
  • Media Capture working group (MediaStreams, getUserMedia()) likes standardizing mozCaptureStream/mozCaptureStreamUntilEnded, and extending to canvases

Necko (dougt/jduell)

  • New HTTP cache has landed!
    • http://www.janbambas.cz/new-firefox-http-cache-enabled/
    • gets rid of largest sources of jank in the browser: other than some startup jank we appear to have no more janks that are longer than 100ms, even on very slow disks. (note: Honza’s number’s are with a patch that disabled 5 sources of startup jank)
    • 1st hit (uncached) loads are now much faster, since we delay writing to cache.
    • Cache no longer disappears whenever we have “unclean” shutdown (which was ~10-20% of the time)
    • We still have some memory consumption issues to fix on mobile (bug 1013333, and B2G/mobile folks may want to help us decide what amount of RAM cache, etc we should use.
  • TLS proxying (ie. TLS connection to HTTP proxy) has landed. (bug 378637). Enables us to work securely with web accelerating proxies.
  • Akamai will be demo-ing opportunistic encryption (i.e. TLS w/o certs) with us at the upcoming IETF meeting in New York.

Performance (vladan)

No update this week

Seceng (mmc)

  • Ability to test testing public key pins landed last night. We want testers to set “security.cert_pinning.enforcement_level” to 3 and see what breaks, telemetry says errors are less than 10^-4 so we are feeling good about going to production soon.
  • bug 973837 has landed and been uplifted to Beta. It blocks view-source URI’s in the data attribute on <object>, which prevents a variant of the same security hole that necessitated blocking the URI on iframes a few months ago.

WebAPI (overholt)

  • No update this week.

Identity (jedp)

<Read Only>

The new Sync in Fx29 is a success.

New sync has only been released to 10% of population, and already:

  • 530k accounts created
  • Over 400k accounts since Fx29 GA
  • Currently 300k active users

I figure that if the same adoption rate applies to the remaining 90%, our new sync will exceed the adoption of our old sync by a factor of 5 right out of the gate. I would say this is a great thing for Firefox and our users!

Congratulations to Chris Karlof, the sync team, and everyone who helped make this happen.

JS (naveed)

<Read Only>

  • Compiler (JIT)
    • bug 603872 bug 1004923: Made Date.now()/new Date 4 times faster on Windows. This matters a lot for some benchmarks like Peacekeeper. Also greatly refactored PRMJ_Now in the process.
    • bug 1000344: (Optimize polymorphic property gets/sets accessing the same slot), this was about a 17% win on Octane-Gameboy.
    • bug 995704: large frames in Ion breaking on win32. Landing caused perf regressions on Win32. Need to fix.
  • Garbage Collection
    • B2G rooting analysis is running! Only 8 hazards detected.
    • bug 959787: Finished converting all public API functions that can GC to take handles
  • Front End and Other
    • bug 1002864: neuter(asmJSArrayBuffer, “change-data”) hits an assertion
    • bug 987995: In crash dumps, record whether a JS OOM occurred recently

Media (mreavy)

<Read Only>

  • bug 881512: MSE/VP9 video plays on YouTube but not ready to pref on yet
  • MediaStreamGraph refactor continues soon; next phase nearing reviews
    • final result should cut delay and eliminate sources of underruns/delay buildups for some webrtc and Web audio uses
  • webrtc.org 3.50 update should be ready this week we hope
  • Media oranges are a major focus. Many WebRTC ones are tied to the test_ipc or e10-s tests (especially some ICE failures).
    • suspect TYPE_REPEATING_PRECISE timers used in fake audio streams are causing some of the other test-didn’t-finish failures

Necko (dougt/jduell)

  • HTTP/2 draft 12 implemented, interops with Twitter. alt-services is next up.
  • HTTP cache2 trial run turned up a couple good bugs. We only have one major test failure (test_seek) that we may need help with.
  • Seer has been turned off. We’ve decided to scrap SQLite and use the HTTP cache to store all the data.

Performance (vladan)

<Read Only>

Performance fixes:

  • bug 785487: Search service was falling back to synchronous initialization
  • bug 988292: Avoid main-thread IO for {profile}\addons.json

Performance measurement & regression tests:

  • bug 936630: Added new test measuring time to restore a session
  • bug 1006551: Working on new Talos test to measure smoothness of scrolling using the more realistic TP5 pages
  • bug 1006531: Modifying Talos tests to measure OMTC performance
  • bug 982598: Helping out with HTTP cache2 regressions

Other:

Seceng (grobinson)

  • bug 744204: Public Key Pinning (built-in) has landed in nightly (default off). To enable it change the preference “security.cert_pinning.enforcement_level” to 1 (allow MITM) or 2 (strict enforcement). This will enable pinning for addons.mozilla.org and the mozilla cdn.
  • bug 858787: Flipped the pref for B2G to use CSP 1.0 by default (for the default policies and for manifest-supplied policies). This was a blocker for landing and enabling the new CSP parser on B2G, a project which was motivated by perf issues caused by CSP on B2G.

Shumway (tschneidereit)

<Read Only>

  • getting close to landing the nat branch, containing huge refactorings, on master. That’ll bring fundamentally better compatibility and, almost more importantly, test coverage for the ActionScript virtual machine and our native bindings
  • timeline event handling is much improved on the nat branch. Passing extensive test suite
  • prototype implementation of Shumway as a jsplugin, based on the work in bug 558184
  • ShumwayWorker now WebIDL-based. Should land (on Nightly only, preffed-off) soon-ish
  • good progress on GL rendering backend

WebAPI (overholt)

  • No update this week. Work continues on PBackground-ification, Web sockets in workers, Broadcast Channel API, Manifest implementation, Service Workers, …

11:08 mcote: bug 995139
11:09 mcote: afaik the current state is that the old data (pre April 9) is unrecoverable
11:09 mcote: but cyliang is going to try to fix the holes in the last few weeks of data
11:10 RyanVM|sheriffduty: someone needs to mute
11:10 RyanVM|sheriffduty: loud humming noise
11:10 davidb: RyanVM|sheriffduty fixed? (it was probably us)

11:15 KaiRo: RyanVM|sheriffduty: ah, didn't know that, good to know
11:15 RyanVM|sheriffduty: KaiRo: ok, it was disabled on trunk/release yesterday, aurora/beta today if we want to be picky
11:16 KaiRo: RyanVM|sheriffduty: thanks, I only knew about release
11:22 laura: mcote: yeah I heard you mention it, didn’t realize it was that bad
11:22 laura: sorry for your trouble

The Need To Know

(Release and system issues that may impact engineering this week.)

Notices/Schedule (lsblakk/sylvestre)

  • Firefox 29 has shipped
  • Firefox 24.5.0 ESR also
  • Firefox 30.0beta1 is with QA – release date is Thurs May 1
  • Firefox 31.0a2 Aurora updates will be unthrottled on Friday May 2 after QA signs off
Next Merge: June 9, 2014 Next Release: June 10, 2014
Trains
Central: 32 Aurora: 31 Beta: 30 Release: 29

Build Changes (gps)

(Build changes of which engineers should be aware.)

RelEng (catlee)

(Repo, test, and other information for engineers from the release engineering team.)

Upcoming Outages/Upgrades

(System outages/upgrades and tree closures that impact engineering.)

Quality Programs

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

OrangeFactor (ryanvm)

  • Past week’s OrangeFactor: 10.29 (Previous Week: 11.23).
  • Thanks to Randell Jesup and JW Wang for fixing a number of media test crashes/failures.
  • Thanks to Nathan Froyd for investigating and fixing common patterns contributing to test instability.
  • Joel Maher pushing ahead with mochitest-bc run-by-dir work (bug 992911). Please take a look at dependencies of that bug for work that needs to be done so this work can land.
  • 22 intermittent failures fixed in the last week – List – Thanks!.

CritSmash (dbolter)

  • uptick in sec bugs delta this week. Your attention appreciated.

MemShrink (njn)

  • Bobby Holley implemented the discarding of chrome script source code on B2G. This saves 1.26 MiB on Tarako (a big deal!) and a bit more on other B2G devices.
  • We’ve had two out-of-band MemShrink meetings recently to deal with a surge of Tarako-related bugs, many of which are of the form “Do something in app A, then something in app B, and app A and/or B crashes due to OOM”. Some of these can be fixed by fixing one thing, but the device has so little memory that for many of them won’t be fixed without root-and-branch memory optimization efforts.

Stability (kairo/bsmedberg)

  • Overall numbers look good, with the exception of Android Nightly, but the bugs there are well-tracked and being worked on.
  • In fact, the most-recent data for beta on both desktop and Android show that we should have fixed all crash-volume-regressions just in time and should have a pretty decent release out the door today!

Team Stand-ups

(In <2 mins, what did your team accomplish last week, on what is your team working on this week, and on what, if anything, is your team blocked? No questions during the stand-ups. All questions should be asked during the roundtable.)

DOM (jst/overholt)

  • New DOM bindings for Window close to landing!

Electrolysis (e10s) (blassey)

  • e10s stability is pretty good. Most people on the e10s team dogfood e10s all the time.
  • bug 982938 – Always save session on exit
  • bug 992415 – Fixed FilePicker crash
  • bug 997446 – Add “Open e10s Window” to hamburger menu (to make testing easier for our Windows friends)
  • Getting help from some contributors working on Good First Bugs.
  • Website to track add-on compatibility coming soon!

Firefox Desktop (gavin)

Firefox Mobile (mfinkle/blassey)

  • WIP
    • bug 776027 – Add Web Activities support to Android r+’d
    • bug 946022 – Implement requestAutocomplete for Firefox for Android r+d
    • Continued work on Home Feed and World Cup add-ons to be featured for Fx30
  • Landed
    • Fx31, bug 994989 – Move Save as pdf to the Page menu
    • Thanks for getting this fixed for Fx30 bug 996062 – [meta] Low-res and slow painting issues when scrolling subframes in Fennec
    • Uplifted to Fx31: bug 949178 – Remove reading list button from reader mode toolbar
