Gaia/Team/Taipei/Meetings/2013-11-19

GFX (milan)

  • Have the preliminary priorities for Q4, Q1, Q2 next year
  • Sorting out the scheduling
  • Big part of the plan is to finish the large changes around Moz2D and OMTC

Identity (jedp)

Firefox Accounts on FirefoxOS

JS (naveed)

    • Compiler (JIT)
      • bug 927516: Bump Ion script size limit for DOM workers
      • bug 894881: Make accessing typed array properties like byteLength much faster
    • Garbage Collection
      • Garbage collection team is in Mountain View working hard on landing GGC
        • Goal 1 – Static Analysis On
          • Currently on and Unhidden for this week. We will need to have this permanently on to avoid rooting regressions and security issues.
          • Individual developers are now responsibile for rooting hazards they introduce. You can find more information on how to handle these on the wiki SpiderMonkey:ExactStackRooting
        • Goal 2 – Exact Rooting On
          • Dromaeo DOM performance regression – dealt with
          • Deal with remaining hazards this week (23 left) – any help you can on offer this week on these will be greatly appreciated
          • Note 1: We are taking a 1-2% performance regression from exact rooting. We will make this up and more with GGC on.
          • Note 2: When Exact Rooting is turned on rooting hazards become security issues so Analysis needs to remain on as a tier1 test (backout if it fails).
        • Goal 3 – Generation Garbage Collector On
          • Browser crashes
          • Performance tuning
          • Note 1: GGC is working in the shell and is currently even with Nightly on AWFY performance.
    • Front End and Other
      • Work on Module continues

Media (mreavy)

<Read Only>

  • Working to update libvpx to 1.2.0, which will gets us VP9 support (see bug 763495)
  • Media playback team is having their work week this week in Auckland
  • Opera’s latest release supports gUM and WebRTC: http://my.opera.com/ODIN/blog/opera-desktop-18-released
  • The WebRTC team and the Media Recording team are working to enable all the WebRTC APIs (gUM, PeerConnection, and Data Channels) for B2G v1.3. Audio-only calls on B2G work now with mozilla-central and 2 patches applied.
  • Special thanks to new contributor Adrian Cruceru <cruceru.adrian@yahoo.com> for diving into a number of webrtc crash reports and doing some great analysis, and providing patches for several!

Necko (dougt/jduell)

  • HTTP/2 work is proceeding well:
    • up to date with latest draft
    • doing DNS experiment to see if we can use SRV records to store info on whether server speaks HTTP/2
    • a lot of discussion about whether “http:” links (not https) should use “opportunistic encryption” (i.e. no certs) or not. We are leaning towards supporting it.
  • HTTP Cache re-write: complications writing crash-proof index: will miss Q4 but hopefully will land early Q1.
  • No longer doing speculative connections to private network addresses (broke some router admin pages): bug 853423

Performance (vladan)

No update

Seceng (mmc)

<Read Only>

WebAPI (overholt)

<Read Only>

  • Anne and Jonas at TPAC in Shenzen last week

  • marcosc almost ready to publish research and recommendations on “standalone” web apps
  • Thinker would still like feedback on https://wiki.mozilla.org/WebAPI/XHRBatch

Quality Programs

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

MemShrink (njn)

  • The trees were shut again for several days due to OOM-related Win7 M-2 and M-bc test failures. Contributions to the post-mortem and suggestions on how to prevent such problems again are welcome!
  • Matt Woodrow fixed a bad gfx leak that was causing very high memory usage (reported under “heap-unclassified”) on Macs when a browser window was minimized. Nick Cameron added a memory reporter for this memory so it will be reported properly in the future. (Sadly enough, Nick wrote that reporter six weeks ago but it bounced due to it causing PGO bustage on Windows — if it had been present, the leak could have been fixed more quickly. Thankfully the PGO bustage has disappeared now.)

OrangeFactor (ryanvm)

  • Past week’s OrangeFactor: 4.58 (Previous Week: 4.94).
  • See Memshrink update for tree closure post-mortem.
  • 9 intermittent failures fixed in the last week – List – Thanks!.

Stability (kairo/bsmedberg)

  • Overall numbers look good, except for trunk regressions on Android.
  • If you look at stability data on Socorro, note that the “EMPTY” dump signature is changing somewhat due to a better stackwalker with more detailed errors (among other things).

Roundtable

[2:04pm] lmandel: joduinn: We skipped the section.
[2:05pm] lmandel: joduinn: I called out the outage this friday
[2:05pm] dveditz: frequently asked: wtf happened to my addons?
[2:06pm] dveditz: (some of them, anyway)
[2:07pm] jaws: 0 nightly users on Holly right now
[2:07pm] jaws: nightly builds aren't running yet 
[2:07pm] jaws: i will be blogging to try to get some more people running Holly
[2:07pm] joduinn: lmandel: i would like to circle back to them before the roundtable section (or maybe right at start of roundtable)?
[2:08pm] lmandel: gavin: Can you please add your notes and links to the blog posts to the wiki.
[2:08pm] dveditz: how does australis affect F4Metro? the UI is totally different
[2:08pm] dveditz: are there screenshots of Australized Firefox 4 Metro?
[2:08pm] jaws: dveditz: shouldn't affect metro since they are separate frontends
[2:08pm] jaws: dveditz: metro firefox has been australis from day one 
[2:09pm] dveditz: "We were coding a lot of the bugs for pre-australis and post-australis, but the testing has been done on pre-australis."
[2:09pm] dveditz: I guess talking about code in files that changed, even if in parts not used by Metro?
[2:09pm] gavin: lmandel: done
[2:09pm] lmandel: gavin: thx
[2:09pm] dveditz: backend files maybe?
[2:09pm] jaws: dveditz: yeah, i invited bbondy to this channel to get clarification

[2:15pm] lmandel: KaiRo: ok
[2:16pm] dveditz: there's a fair number of popular addons with issues still, will take some time to get those fixed
[2:16pm] • KaiRo just wants to ensure less people are surprised by this new high-profile signature
[2:17pm] RyanVM|sheriffduty: was Try enabled too?
[2:18pm] KaiRo: lmandel: ok, I'm back, can do it myself if it hasn't happened yet

[2:19pm] johnath: yet another peril of running a california-based business
[2:20pm] akeybl: and all the coverage is linking to nightly
[2:20pm] dveditz: johnath: they probably have to put in a new electric meter for the company running the chargers. If they just put in some free plugs I bet they wouldn't have had to
[2:21pm] dveditz: heaven forbid that they let someone have $3 worth of electricity without charging for it
[2:21pm] johnath: heaven and building management
[2:21pm] dveditz: (so now it'll go through something like ChargePro and cost $5)

Quality Programs

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

MemShrink (njn)

The trees were closed for several days due to shutdown leaks. From the post-mortem:

TL;DR: Win7 M2 and Mbc test were OOMing frequently at shutdown because too many DOM windows were open. This was due to a combination of: (a) multiple badly written tests, (b) multiple social API leaks, (c) multiple devtool leaks. Bug 932898 will improve our shutdown leak detection; bug 934288 may also help. Bug 932900 will (if implemented) will make some of these leaks impossible(?).

Roundtable

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

  • [gps] If you use MacBook Pros as your primary developer machine, consider getting a 2013 model ASAP.

  • Thinker is looking for feedback on batching XHR for apps: https://groups.google.com/forum/#!topic/mozilla.dev.webapi/qRIhhEoSMlE

Quality Programs

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

MemShrink (njn)

We can now do fast, coarse-grained, per-tab memory measurements. This will become a devtools widget eventually.

OrangeFactor (ryanvm)

  • Past week’s OrangeFactor: 4.56 (Previous Week: 5.12).
  • 13 intermittent failures fixed in the last week – List – Thanks!.

Stability (kairo/bsmedberg)

  • Gathered some data on stability work within the last year, here are some highlights:
    • Desktop browser crash rate is the same as a year ago (~1.0 crashes per 100 ADI), despite aggressively adding web features in that time
    • Plugin hangs and crashes are less than half of what they were a year ago (when Flash had an all-time-high on issues), thanks to work on both our and Adobe’s side (0.8 -> 0.3).
    • Android crash rate reduced by 67% (2.4 -> 1.6).
    • Nearly 1500 crash bugs fixed within the last year.

<Read Only>

  • Stability numbers for yesterday are still waiting on ADI numbers to arrive.
  • ASUS gamer OSD is now blocklisted on Fx27, which kills our #3 topcrash (pending approval Fx26) bug 812683
  • A new version bitguard.dll is causing signification crash issues across channels. Currently we are unable to blocklist this DLL because it is loaded via APPINIT before the Firefox DLL blocklist is installed. dmajor has a theory of how we can fix this by not linking firefox.exe against user32.dll

Roundtable

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

  • (RyanVM) B2G26 (v1.2) now has its own Gecko branch independent of mainline Firefox.
    • https://hg.mozilla.org/releases/mozilla-b2g26_v1_2/
    • Only koi+ blockers should be landing directly on this branch unless cleared by Release Management.
    • Regular mozilla-beta -> mozilla-b2g26_v1_2 merges will be performed to keep the underlying Gecko revisions in sync.

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.)

Accessibility (dbolter)

Add-on SDK (dtownsend)

No update

App Tools (dtownsend)

Developer Tools (robcee)

Light week. Only 33 bugs fixed including App Manager.

  • Reflows in Web Console landing bug 926371
  • Hoping to get CodeMirror landed for Firefox 27 merge. bug 919709

<Read Only>

  • Added color swatches to Inspector Style view bug 918716
  • Debugger responsive when side-docked bug 927375
  • Better Error handling and display in the Debugger bug 812764
  • Hide Non-enumerable properties in the JSON tab in Network Monitor bug 862344

Firefox Metro (bbondy/jmathies/mbrubeck)

<Read Only>

  • Front end polish and bug fixing continues.
  • APZC: Kats and botond have come over for a short period to help out on all our of scroll and zoom issues. Lots of bug triage took place last week. Most every bug has been updated (bug 886321). Bug fixing will commence after a work week this week.
  • After lots of feedback at the summit, we are seriously considering switching from a separate profile to a shared profile with desktop (bug 924860). Investigation into this is currently taking place. Some key notes:
    • Users would have to chose a default browser mode (metro or desktop) on Win8 and up. Only one mode would be active at a time.
    • Launching the browser from any location (shortcut/tile) would launch into the default mode.
    • Users would be able to switch from one mode to the other within each browser. This would shut down the existing instance and relaunch the other using the same profile.
    • Most everything would be shared, although certain user data sets (most notably bookmarks and prefs) would be kept separate.

If you have any thoughts/feedback on the above please post in the public metro mailing list (metro@mozilla.org), to the tracking bug, or chat with one of us in #windev.

The Need To Know

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

Notices/Schedule (akeybl/lsblakk/bajaj)

Next Merge: October 28, 2013 Next Release: October 29, 2013
Trains
Central: 27 Aurora: 26 Beta: 25 Release: 24
  • FF25.0b1 desktop/mobile was launched last Thursday
  • Aurora 26 was unthrottled on Friday
  • FF25.0b2 went to build last night for both mobile and desktop
    • [resolved topcrash] https://bugzilla.mozilla.org/show_bug.cgi?id=918645 – crash in java.lang.SecurityException: WifiService: Neither user 10061 nor current process has android.permission.ACCESS_WIFI_STATE. at android.os.Parcel.readException(Parcel.java)

36 bugs (17 bugs last week) 52 bugs (54 bugs last week)
Unresolved Aurora 26 Trackers (non-security, not tracked for Beta) Unresolved Beta 25 Trackers (non-security)

Build Changes (gps)

(Build changes of which engineers should be aware.)

  • Add export MOZ_PSEUDO_DERECURSE=1 to your mozconfig for experimental faster building goodness. If you have 64 cores in your machine, the build system will scale up and use them all during C++ compilation. This will eventually be the default building mode. We’re working out bugs. This build mode is susceptible to race conditions. Please use it and report bugs.
  • per-directory xpcshell test targets are being removed in bug 901990. Run individual tests via mach xpcshell-test or by using the top-level xpcshell-tests make target along with TEST_PATH.
  • Run mach build-docs to produce in-tree documentation on the build system.

Upcoming Outages/Upgrades

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

  • IT may need 8?10? hour tree closure this weekend (SCL3 network downgrade). Still being investigated. Details in bug 917349. Watch newsgroups for info. (joduinn).
  • Welcome to Balrog! New AUS.

Key Issues

(Non team specific issues that impact engineering.)

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.)

  • bug 867757: You can now insert arbitrary annotations into Gecko Profiler profiles instead of just plain string markers. It can be used to track interesting things such as IO, memory usage or other timing information. Eventually this functionality will be extended to record stacks associated with interesting events that aren’t captured by profiler samples. Cleopatra UI improvements still to come.

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: 4.6 (Previous Week: 4.69).
  • 24 intermittent failures fixed in the last week – List – Thanks!.

Stability (kairo/bsmedberg)

  • Overall numbers look good, with the exception of Android 25.0b1, which is plagued by bug 918645 (fixed in b2).
  • To enable tests and fuzzers to find stability and security issues more easily, we need our automated test suites to pass in sanitizers (ASan, etc.) – where are we on those efforts?

Roundtable

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

Quality Programs

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

MemShrink (njn)

  • Timothy Nikkel fixed bug 847223, which means we no longer decode all images in a page when its first loaded. This can make an enormous difference on image-heavy pages — we have one example where peak RSS dropped from 2,400 MB to 280 MB. On that same page the loading lag dropped from 5 seconds to 1 second. Assuming no problems are found, the constitutes the completion of the #1 item (“Better Foreground Tab Image Handling”) on the MemShrink big ticket items list! Generational GC will be the new #1.
  • I am in the process of cleaning up the memory reporter infrastructure. One major change that just landed is that nsIMemoryReporter was removed, and nsIMemoryMultiReporter was renamed as nsIMemoryReporter. It’s possible that this might break functionality in some add-ons.

OrangeFactor (ryanvm)

  • Past week’s OrangeFactor: 4.69 (Previous Week: 3.41).
  • Shout out to Victor Porof of the devtools team for landing some major cleanups to the debugger test suite in bug 876277.
  • *30* intermittent failures fixed in the last week – List – Thanks!.

Stability (kairo/bsmedberg)

  • Overall numbers look good for releases and uplifts.
  • Nightly is a mess, but the bugs are all filed and appear to have owners.

Roundtable

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

  • Is Haida targeted at desktop platforms (or Android)? The page seems be to all oriented to B2G. Whe will be the change; how well will this match with OS UIs and across all platforms?
    • B2G only
  • What changes should we expect for about:home (lmandel)
    • Focus on top sites more than bookmarks

<Read only beyond this point>

Friends of the Tree

There were lots of 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.)

Good Reads

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

The Need To Know

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

Notices/Schedule (akeybl/lsblakk/bajaj)

Next Merge: September 16, 2013 Next Release: September 17, 2013
Trains
Central: 26 Aurora: 25 Beta: 24 Release: 23
  • FF24.0b10 for Desktop and Mobile have gone to build
    • Backed out bug 881634 – crash in mozilla::gfx::DrawTargetSkia::DrawSurface for Fx24.b10 to resolve bug 911502
57 bugs (46 bugs last week) 18 bugs (30 bugs last week)
Unresolved Aurora 25 Trackers (non-security, not tracked for Beta) Unresolved Beta 24 Trackers (non-security)
  • RelEng doing branch setup this week for FF24, FF24esr, TB24, TB24esr and b2g v1.2.

Build Changes (gps)

(Build changes of which engineers should be aware.)

<Read Only>

  • Builds in automation (and presumably developer machines by extension) have been getting faster!: http://brasstacks.mozilla.com/gofaster/#/executiontime/build?range=60&include_outliers=0
    • Combination of C++ header dependency elimination and core build system changes.
  • Build tiers have been inverted. Expect some fully concurrent building soon \o/
    • This clearly shows how much C++ compilation dominates build times. Anything you can do to reduce C++ compilation time will make the build faster. This work is largely outside the scope of the core build config group.
  • |mach test| has landed. You can now run test suites by their TBPL abbreviation e.g. |mach test M1|. Not all tests supported. File bugs against Testing :: General to plug gaps.

Upcoming Outages/Upgrades

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

  • treeclosure from last night SCL1 outage as part of rollout DNS change: details in bug 914570. Gap in nagios coverage, so IT setting up nagios alert in bug 914735

Key Issues

(Non team specific issues that impact engineering.)

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.)

  • WebIDL-only event generator is ready to land, so no more need for nsIDOMFooEvent interfaces for events. Bug 900904
  • We have unified exception handling on workers and main thread now. Bug 911258
  • Thread-agnostic event dispatching is the last major worker/main-thread parity blocker Bug 853893
  • Also thinking about what event loops should look like. Bug 914762
  • janv’s temporary storage work is about to land Bug 785884

Firefox OS Productivity (doliver)

Last week:

  • The first cut at email notifications has landed! https://bugzil.la/892519
    • These should be pretty functional, so go ahead and give it a shot. Visit your account settings to turn on notifications for existing accounts.
    • New accounts will have the option to turn them on during setup
    • Note: as currently implemented, you may find notifications overly enthusiastic — every new mail will wake up your screen and play a sound. We are working with the systems team this week to see what we can do to add a less exuberant class of notification to use for less urgent cases like this.
