OrangeFactor (ryanvm)

<Read Only>

• Past week’s OrangeFactor: 3.44 (last week: 5.01).
• The top of the list is mostly dominated by mobile failures, both B2G and Android.
• Waiting on Aurora approval requests for MediaStreamGraph refactor fixes that were causing frequent oranges.
• 16 intermittent failures fixed in the last week – List – Thanks!.

MemShrink (njn)

• Boris Zbarsky fixed a bad memory leak. If you were seeing ghost windows in your Nightly build recently, this is probably the reason. The patch has been backported to Aurora.

Stability (kairo/bsmedberg)

• Release has about 10% of all crashes in three bugs that are somewhat concerning: bug 1062452 (~5%, GFX), bug 1063048 (~3%, GFX), bug 1063052 (~1%, Layout)
• Desktop Beta has high crash rates due to multiple GFX crashes in the top ranges, probably OMTC/D3D11 work
• Mobile Beta has two GFX bugs that cause bad crash rates: bug 1028802 (was supposed to be fixed in 33 but isn’t), bug 1041744

  • UNASSIGNED #1: bug 1054292 – Intermittent Android TEST-UNEXPECTED-FAIL | remoteautomation.py | application timed out after 330 seconds with no output (“org.mozilla.fennec still alive after SIGABRT: waiting…”, [@ libc.so + 0xd1fc]).
    • Widespread failures make this difficult to handle.
  • UNASSIGNED #2: bug 1054456 – Intermittent Android talos command timed out: 3600 seconds without output running [‘/tools/buildbot/bin/python’, ‘scripts/scripts/android_panda_talos.py’, ‘–talos-suite’, ‘remote-tp4m_nochrome’, ‘–cfg’, ‘android/android_panda_talos_releng.py’, ‘ …
    • Failure rate high enough for hiding by default.
  • UNASSIGNED #3: bug 1033098 – Intermittent B2G runner.py | application crashed [@ mozilla::gl::GLBlitTextureImageHelper::BlitTextureImage(mozilla::gl::TextureImage*, nsIntRect const&, mozilla::gl::TextureImage*, nsIntRect const&)].
    • Will lead to Gaia Python Integration tests being hidden on OSX if not addressed soon.
• 28 intermittent failures fixed in the last week – List – Thanks!.

<Read Only>

1. https://wiki.mozilla.org/TPE_RIL_team/2014-08-26

GFX (milan)

• Desktop:
  • OMTC on Windows has a few issues remaining; it’s still riding 33 (Aurora), and we’re hoping that we can leave it there, a version ahead of the plan, by landing those fixes this week.

Firefox OS:

• Features for 34/2.1 generally on track:
  • Vsync related work done in the Taipei graphics team is going to land behind pref, but we’re not drawing attention to it as it is a “preparatory” work anyway.
  • Multi-layer-apz work (bug 1026271) is going down to the wire. There is a bit more layout work to be completed in the prerequisite bug 967844, and that’s a sizable patch, so some of it may start behind a pref as well. On the other hand, this layout work is a prerequisite for async scrolling on desktop, so it’s worth the wait.

  • Landed COW arrays

Layout (jet/dbaron)

<Read Only>

• CSS font features (font-variant-* properties and @font-feature-values rule) now enabled on trunk, and font-feature-settings unprefixed (bug 975744)
• Unicode database tables updated to version 7 (bug 1057548)
• imgIContainer::Draw refactoring landed (bug 1043560), improving numerical accuracy (rounding), and paving the way for future improvements such as downsample-on-decode and media fragments

Media (mreavy)

• Massive MediaStreamGraph refactoring to make it driven off the output audio pulls should land today/tomorrow (bug 848954)
  • Should reduce latency and improve quality

  • https://lists.mozilla.org/pipermail/dev-tech-gfx/
• Firefox OS:
  • Some last minute blockers. The biggest recent graphics bug turned out to be an intermittent, low level network/ipc issue, usually only showing up during multi-day partner testing. Currently looking at a couple of canvas issues, related to the updated version of Skia (back in March.)
• Desktop:
  • Will try to get to final stage/land desktop tiling the week of September 22nd – probably behind a pref until APZ on desktop is available, to avoid performance issues. The aim is to have it (the tiling) stick in 35, but we may need to test with that pref enabled, to avoid regressions while APZ work is being done.

• minor fixups for HTTP2: we’re close to being able to pref it on.

Performance (vladan)

• bug 1045108: Please review your Telemetry probes and make sure they’re still useful. Also please set the expiry dates for your probes (e.g. “expires_in_version”: “never”, or “35” for Firefox 35) — we’ll be automatically marking unclaimed probes for expiry in Firefox 40.

• This is not exactly MemShrink, but Eric Rahm improved the deadlock detector so it runs much faster and uses vastly less memory, which makes debug builds less painful to use.

Stability (kairo/bsmedberg)

• Beta crash rate is high due to an adware-related crash that got worsened by trying to fix it (see bug 1038243). Cause seems to be a forgotten bump of IIDs which will be done in bug 1051858.

Profiler Update

Last week, Victor Porof (:vp) attempted to land the New Profiler UI in bug 879008. He had to back it out due to leaks occurring in the Profiler back-end. We logged bug 1047124 to investigate this and some quick discussion with Benoit Girard suggested there was a leak.

We’re going to land the new Profiler front-end with the 15 or so tests that cause this leak disabled.

A little further investigation showed the tests from our original in-tree Profiler were disabled back in February bug 973974 and never re-enabled.

We’re going to talk to Kannan Vijayan this week to ask if he has any chance to look into this. He’s been fixing Profiler crashes for nearly 6 months and rewriting the JS backend of the profiler in his spare time. Hopeful we’ll be able to get these tests working again as we’ve been running blind since they were disabled.

Any additional help or insight please contact me (robcee) or Victor (victorporof) in email or IRC.

GFX (milan)

• Desktop
  • Linux: bug 1015218 – Use Cairo image surfaces and XShmPutImage instead of XRender on GTK/Linux OMTC basic – landed. This will help us with getting Linux closer to other desktop platforms and be able to share more effort that benefits them all (by eventually moving to Skia.)

• Mobile:
  • Looked at the home screen memory usage, and whether we have to switch to “four icons across” to help that situation. As of right now, four across helps compared to three across, but not enough to force us to do it, so the proposal is to go back to three, while maintaining the hunt for any less than efficient memory consumption.
  • Will try to switch Fennec to use the same APZ code as B2G (and eventually desktop), to put them on the equal footing.

Need To Know

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

Notices/Schedule (lsblakk/sylvestre)

Next Merge: September 1, 2014		Next Release: September 2, 2014
Trains
Central: 34	Aurora: 33	Beta: 32	Release: 31

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: N/A (data collection issues) (Previous Week: 9.26).
• Intermittent mochitest-bc docShell leaks (bug 1036031/bug 1036036) remain highest unowned failures on the list.
• #4: bug 1040724 – Intermittent test_visibility.html | Plugin should have painted once. (expected 1 independent paints, expected 1 logged paints, got 2 actual paints)
  • Started on Friday, fallout from all the plugin activity last week?
• 15 intermittent failures fixed in the last week – List – Thanks!.
  • Shout-out to Sami Jaktholm for fixing lots of devtools issues recently.

MemShrink (njn)

• Jan de Mooij enabled optimized Latin1 strings in the JS engine. This saves over 4 MiB when starting Firefox and loading Gmail using a Latin1 locale. (And it’s still a win on non-Latin1 locales and pages because they still use lots of Latin1 strings, identifiers, etc, and Firefox’s own JS code is still written mostly in Latin1.) This also speeds up some string-intensive operations such as some regexp operations.
• (BTW, this change is also a textbook example of how to break up a large change into lots of small, manageable pieces, which leads to faster reviews, clearer progress, and easier bisection of introduced defects. See the tracking bug for details.)
• Lots of B2G 2.0 memory usage regressions have been getting fixed recently (e.g. here and here) involving too many people to list individually. Lots of great work between the MemShrink team and the Systems Front End team.

Stability (kairo/bsmedberg)

<Read Only>

• Nightly had a startup crash in yesterday’s first build, is fixed.
• Otherwise, overall data looks decent.

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.)

irc #planning Log From This Meeting

11:06 overholt: clouserw, maybe it'd be neat to have a marketplace update every once in a while at this meeting
11:10 dveditz: cpeterson: jedp isn't here anymore... maybe take the Identity section out of the template or find a new owner?
11:11 cpeterson: dveditz: thanks. do you have a owner in mind? :)
11:12 dveditz: no, I don't know what's up there these days
11:12 dveditz: maybe replace Identity with FxA?
11:13 cpeterson: ok
11:14 overholt: cpeterson, I wanted to quickly mention some DOM and WebAPI Q3 goals but I added them to the wiki after we started
11:14 cpeterson: overholt: we can come back to you next
11:14 overholt: cpeterson, perfect, thanks
11:18 lmandel: clouserw: Speak with Marco Mucci and Jenn Chaulk.
11:18 clouserw: thanks
11:18 lmandel: clouserw: bsmedberg also suggested that you speak with madhava.
11:18 clouserw: yep, will do. thanks
11:18 bsmedberg: clouserw: FWIW, my impression is that the app support in Firefox is half-baked and isn't ready for release
11:19 clouserw: bsmedberg: we have to ride the trains though
11:19 bsmedberg: but that was from a survey of the status a quarter ago
11:19 clouserw: right
11:19 dveditz: fx33 ends this week
11:19 dveditz: -end
11:19 clouserw: it's much improved

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

<Read Only>

• 31b8 build 1 built on both Desktop & Mobile. Waiting for QA sign off to go live
• GGC won’t ship with 31 but in 32. Causing too many issues in term of stability (OOM) Bug 994589 for more info
• Other top crash: bug 988549 (GFX blocklist)

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: 7.65 (Previous Week: 9.18).
• Numbers improving after another recent batch of test disablings and a number of fixes landing.
• #1: bug 1007230 – Timeouts during pip install.
• New serviceworker tests are flaky on Android/B2G. Seems too risky to backout at this point, so action needed on the various bugs on file.
  • bug 1031928 and bug 1032610
• 34 intermittent failures fixed in the last week – List – Thanks!.

MemShrink (njn)

• No update.

Stability (kairo/bsmedberg)

• Overall numbers still don’t look entirely good:
  • Aurora is just still seeing some people on the bad builds from last weekend, crash data for newer builds is fine
  • Beta 31 has ~30% worse data than 30, due to 3 areas:
    • Experiments shutdown crashes (bug 1012924, no effect on release which doesn’t run experiments).
    • GGC OOM crashes, mostly bug 999158. Sadly, we’ll need to disable GGC on 31.
    • GFX crashes, see bug 988549, due to blocklist for D2D (at least) not working correctly. GFX team is looking into it.

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.)
