Blog Shout Out
Stability Wins
  • The team worked hard to pull together patches to address the DB locking crashes for Firefox 20 beta 1 which shipped yesterday:

    • bug 843029 – Add more retries to ensureDatabaseIsNotLocked

    • bug 843361 – Dump list of open files if we fail to unlock the DB
    • bug 732902 – java.lang.IllegalStateException: at android.widget.ListView.layoutChildren(ListView.java) with Adapter
    • bug 836924 – java.lang.NullPointerException: at org.mozilla.gecko.Tabs.getContentResolver(Tabs.java:212)
  • Awesome find/fix hit trunk for: bug 839882
Memory, Responsiveness, and Usability
  • Nice responsiveness improvement hit central yesterday with the landing of bug 843888 – LayerView has 1 overdraw

  • We are very stoked \o/ on the landing of bug 716859 and the patch for bug 829747. The build we are showing at MWC contains both these patches
Great progress on
  • WebRTC is being showcased this week at MWC, we’ll work on a schedule after folks regroup post-the show

Stability Report [Weekly]

  • Bugs needing help/attention:

    • bug 837370 (js::types::TypeCompartment::addPendingRecompile), assigned to dvander, high on Aurora 21

    • bug 787158 (nsHttpConnection::OnSocketWritable), assigned to mcmanus, high on Beta 20 and later, probably triggered by Facebook SPDY trials
    • bug 844580 (js::ObjectImpl::nativeLookup), preliminarily assigned to dvander, high on Beta 20 and later, might just be another generic signature for JM crashes but we want to be sure of that before ignoring it for the moment
  • A class of crashes with integrated AMD Radeon graphics is creating huge spikes of crashes in release builds recently (e.g. bug 830531 on 19 release with Win8, bug 839270 on 19.0b5 mainly with Win7). This looks like a chipset or kernel-mode driver problem corrupting read-only memory and making us crash, we have tried to contact AMD people, no resolution thus far, but they are investigating.
  • If you’re interested in more details about our stability efforts, please join the CrashKill meeting every Monday at 10am Pacific in the Stability Vidyo room (also see dev.planning announcements).

Snappy [Bi-Weekly]

Startup & Shutdown
  • bug 810454: Read-ahead entire sqlite cookie DB on DB connection open

    • Experiments show 50% faster DB open time for a larger cookie DB (1.5MB)

    • 87% regression for smaller cookies DB (512KB), but small in absolute terms. See bug for data & details.
    • Plan to do a Telemetry trial to verify benefit in the field
    • Pre-loading LocalStorage DB bug 842777 and Flash shared library bug 836488
Tab Strip
  • bug 828097: We now have Telemetry for Tab animation smoothness

    • Tab animation intervals are good when opening a blank page, not very good when newtab preview is enabled (regardless of browser.newtab.preload), especially on slow systems.

    • Telemetry: http://goo.gl/LHjTZ
  • bug 838758: Gradient cache keys were too precise. Avi landed a patch to key the gradient cache on gradient stops instead.
    • This patch eliminates big memory spikes on some systems (HD4000) – bug 837542

    • D2D speedup 20-25% for tab animation.
  • bug 837885: We’re working with fx-team (MattN, mconley) on Australis performance
    • Benchmarks: http://goo.gl/TOXLe

    • Now at about 15-20% regression from default theme on slow systems
  • Timer interval irregularities hurt animation smoothness:
    • bug 842967 – timer may retarget the same timestamp

    • bug 590422 – remove timer compensation/smoother
Content
  • bug 842852: Improve LocalStorage performance by check-pointing the WAL log more frequently + preventing latch-up of reader and writer threads.
Hangs
  • bug 825588: Paolo landed the skeleton for a new downloads API. Iterating on features and will eventually port over callers

  • bug 789348, bug 820834: Marco working on removing uses of LocalStorage from about:home
Add-ons
  • bug 810149: Addon Manager recursively scans unpacked addon directories for changes on startup. We would like to only check extension install manifests

    • However, we’re seeing very high number of Telemetry reports of unpacked addons getting updated without any changes to their install.rdf.

    • If you see “addonManager: {“modifiedExceptInstallRdf”: n > 0, …}” in your about:telemetry’s “Simple Measurements” section after starting Firefox, please contact Irving or Vladan.
Tools
  • We’ll soon begin receiving reports of any Firefox late-writes (part of making shutdown faster)
Other
  • bug 840651: Telemetry ping storm from a few machines, idle-dily firing too much?

Memshrink [4th Tuesday of Month]

Some recent big wins:

  • Timothy Nikkel fixed bug 689623, which greatly reduces memory consumption on image-heavy pages. This is a big deal — it was the #1 item on the MemShrink “big ticket items” list!
  • Two bad areweslimyet.com regressions from December were fixed by Seth Fowler and Peter Van der Beken.
  • Chris Jones fixed a bad B2G leak that was causing B2G phones to become unusable after a couple of days of use.

Custom runs (from try builds) can now be requested on areweslimyet.com.

MemShrink reports: week 85–86, week 87–88.

If you are interested in attending MemShrink meetings, please feel free to do so. The next one is Tuesday, March 5th at 2pm PST (watch for Jet’s announcement email to dev-planning). The MemShrink regulars have some expertise when it comes to the DOM, JS engine, cycle collector, B2G and Fennec, but participation and engagement from people who know about things such as gfx, images, layout, jetpack, and front-end would be extremely welcome. Feel free to contact nnethercote if you want more information.

Roundtable

  • 3rd and final reminder that next week’s meeting will be in the Engineering Vidyo room (lmandel)

  • (catlee) More linux32 test slaves online now. bug 843054
  • TSan (thread sanitizer) Firefox now builds on Linux. Useful for debugging race conditions which might be the underlying cause of many intermittent test failures. Contact choller or cdiehl for more information.

Stability Report [Weekly]

  • Thanks to roc for his investigation and wallpaper in bug 839270 – unfortunately the real causes still eludes us. roc might need the support of a developer with access to a crashing machine, esp. if he can’t do good remote debugging.

Critsmash [3rd Tuesday of Month]

Trunk landings

  • bug 833777 – UI fails to load intermittently

  • bug 674739 – Implement DOM3 KeyboardEvent types for audio
Great progress on

  • Landed in trunk, bug 834681 – Add support for basic distribution modifications

Stability Report [Weekly]

  • Need input/ideas on bug 837835 – increase in crashes with EMPTY dumps (ESR is even worse: bug 830808)

  • bug 798274 is a trunk crash that came back recently from being very intermittent – needs an assignee and some investigation.

Firefox for Android

  • What do we do about Flash (unsupported by Adobe, esp. since Android 4.0+)? ( spreadsheet of flash crashes)

    • Though Flash support is a major feature, it’s also one of the largest pains we have, esp. in terms of crashing

    • >15% of all crashes in 19.0b5 are Flash-related (probably more, this is only based on the top signatures and obvious indicators for Flash being involved)
    • Because Adobe doesn’t care, those are really hard to debug, Flash is a “black box” for us
    • If we continue to support it, can we put Flash in its own process like we do for desktop?
    • Sumo has mentioned that we get more complaints that flash isn’t available more so than the reports of crashing.
  • Filed bug 840634 – [meta] What should we do about Flash in Fennec?

Snappy [Bi-Weekly]

  • Windows with Intel GPU – when resizing window eats 5Mb/s (?) while resizing
Content
  • Bumping Plugin Hang UI timeout from 5 seconds to 11 seconds

  • Honza’s working on a rewrite of DOMStorage (bug 600370)

  • Firefox for Android tablet UA change (dropped “tablet” token) was reverted. Not clear yet if this will reland (bug 829596)

  • Embedded YouTube videos do not play in iFrame (bug 834965) seems to be a regression
    • Do we have unit tests for our UAs?

Open Sans and Charis for Content
  • As part of the Readability 2.0 feature, bug 831354 – Ship fonts for content in Firefox for Android landed in central after a heroic effort on part of UX and Johnathan Kew to correct test failures and provide follow up patches such as bug 831883 – eliminate the Open Sans fonts bundled in the Reader core theme, just use Gecko’s “installed” copy in order to are mitigate the resulting package size increase by about ~200k. this also happens to fix bug 792370 – Reader Mode lacks proper italic and bold faces for Open Sans.

  • We are also looking into a possible talos regression bug 833000 – Talos Regression trobopan on Android, 40%, Jan 19
  • Once we have the above issue nailed down, we will figure out if this will ride the trains for Fx21 or if we’ll uplift to Fx20
Memory, Responsiveness, Usability
  • Regression in fX21 fixed: bug 831188 – about:plugins lists blocklisted and user-disabled plugins

  • Also part of the Readability 2.0 effort, a prototype is under test/iteration bug 757257 – font inflation element grouping
  • Fix for IME regression has landed and is being targeted for aurora bug 825120 – Previous composition is not cleared when changing focus from old to new input

In progress/under investigation
  • bug 826385 – “Clear private data” not clearing cache.

Stability Report [Weekly]

  • Trunk bugs needing traction:

    • bug 827946 (Linux, skia::BGRAConvolve2D), no comment from Joe in a week and this is huge for a Linux crash (>3% of all crashes).

    • bug 830654 (js::ObjectImpl::getPrivate), needs owner
    • bug 827171 (nsPluginStreamListenerPeer::OnStartRequest, mobile), needs owner, also affects Aurora seriously

Snappy [Bi-Weekly]

  • Jan 17 status

  • Snappy updates move to bi-weekly after next week

Memshrink [4th Tuesday of Month]

  • The new, easy-to-use version of DMD landed. about:memory is our main tool for understanding and reducing memory consumption, and DMD is our main tool for making about:memory better. It was particularly helpful in improving our understanding of B2G memory consumption.
  • A bad memory consumption regression has made it onto Aurora. It relates to a refactoring of image-handling code. Seth Fowler is investigating. We wouldn’t have noticed this without AWSY.

Stability Report [Weekly]

  • Trunk crashes needing an owner or attention:

    • bug 827946 – skia::BGRAConvolve2D

    • bug 828034 – mozilla::ipc::RPCChannel::EnteredCxxStack
    • bug 830654 – js::ObjectImpl::getPrivate
    • bug 829909 – nsWindow::Enable @ UserCallWinProcCheckWow (was assigned to aklotz by release management, needs attention)
  • bug 806820 – probably Facebook-triggered, connected to iterators in JS
    • If anyone has been seeing this, we’d be very happy to find steps to reproduce so it can be debugged.
  • bug 822438 – js::Interpret or js::mjit::JaegerShot on wiadomosci.onet.pl
    • Haven’t heard back on our Polish contact trying to get a sample of the code that was pushed and then pulled back on that site.

    • If anyone has contacts to that site or can help us to get in contact with their team to receive a sample of that code which was triggering our crashes, that would be very helpful. We know it’s a bug on our side that they triggered, we need to try and reproduce as the stacks aren’t too helpful, though (unless someone can get a clue by looking into minidumps).
  • On a positive note, the JS team is apparently successfully hunting down compartment mismatch crashes in bug 821733, which should probably fix some issues that would otherwise not be as easy to track down.

Snappy [Weekly]

Games [1st Tuesday of Month]

  • Any bugs that are found that are likely game related should be marked with a whiteboard tag [games:p?] and we will review in our next triage. It’s a huge help to us when people call these out.
  • Benchmarking

    • We are hoping to have the benchmarking running by the end of the month. We are also preparing a list of benchmarks and will post that on the games platform section as soon as that’s available. A list of benchmarks will be available minimally, the goal however is to have the automated framework running.
  • WebAudio

    • Development has been good but a few of the resources that we wanted couldn’t get to it due to B2G. Roc is now working on it and this is on our Q1 goal list. Alan Kligman is working on conformance tests.
  • External Partner Support

    • There is a lot of focus in the short term on this due to MWC in February and GDC in March. Plenty of work going into demos and supporting partners improve performance.
  • BananaBread

    • Currently working via WebSockets.

    • WebRTC support is currently underway and expected in the near future.
    • Planned to work on a Mobile version as soon as Vlad returns from vacation.
  • ASM.js

    • Work is continuing and performance numbers are very encouraging. Current micro benchmarks are coming in around 1.x of native and about 2-6x faster than SM.
  • bug 731974 – requestAnimationFrame stability, takes us from 50% bugs hitting 16 or 17 milliseconds to 90% with a much tighter grouping around the target time frame. Still not to 99.6% which is where Chrome sits. The remaining instability should be resolved we solve related issues such as tabs affecting each others performance and GGC.
  • bug 828954 – Firefox 18 Breaks Unity player on 18 for Mac Users. This is likely going into 18.0.1 if there is one and will be in 19.0.0 otherwise.

    • bug 829284 – Unity plugin doesn’t display in HiDPI mode, when this will be resolved is less clear.
  • bug 716859 — Jeff is landing this very soon, which will improve our WebGL performance on mobile devices and sets the stage for future perf boosts on all platforms.
  • bug 825205 — WebGL regression around buffer validation that’s been fixed in 19.
  • GDC – We will be in attendance and have some passes so contact mbest@mozilla.com for more info if you are planning to attend. I need to find out fast as we need to give them a list end of day!

Mobile Web Compat [2nd Tuesday of Month]

  • UA overrides for 5 locales in B2G

  • Working on staffing and community plan to ramp up the effort in 2013
  • Vimeo mobile formatted videos now play on Firefox for Android and Firefox OS

Critsmash [3rd Tuesday of Month]

  • Goooooooooal!!1!

    • For the 2013 security HULKSMASH please work with your team to make an explicit goal that makes sense for your components. Someone from each team should have received an email from davidb and should be championing team discussion for this goal. Please contact davidb with questions.

      • Written only status updates for platforms, other pieces (discuss)

  • No meeting next 2 weeks

Products/Projects

Firefox OS

  • blocking-basecamp. This will only be used up until v1.0 CS (hopefully 1/15), and will ultimately only include those bugs that require Mozilla engineering action prior to v1.0 CS.

  • blocking-b2g. This flag is meant to track groups of partner work, without specifying a targeted version. Example values would tef+ for critical issues found after we’ve deprecated blocking-basecamp, or shira+ for issues blocking a partner’s required features.
  • tracking-b2g18. This flag is used similarly to tracking-esr17 and is meant to specifically track major stability/security/usability that we’d like to fix int he v1x timeframe. The value can either be set to + (generically tracked) or for a specific 6-week cycle (19+, 20+, etc.). It’s been proposed that tracking-b2g-v1x may be a better flag, as it pertains to both Gecko and Gaia.
  • status-b2g18. This flag is used similarly to status-esr17 and is meant to track whether a fix has been landed on v1x release branches. It’s been proposed that status-b2g-v1x may be a better flag, as it pertains to both Gecko and Gaia.
