Firefox OS Productivity (doliver)
Firefox OS Telephony/WIFI/NFC (kenhkchang)
- bug 989595 - [Tarako]wifi stay searching after turn on/off wifi some times
- bug 984919 - [RIL][DSDS] New calls an inactive SIM when there is an active SIM should be rejected
- bug 889737 - [MMI] Unify both sendMMI() and dial() functions

- bug 959434 - [B2G][NFC]Support secure element for NFC daemon.
- bug 978027 - [B2G] Need to implement API for getCdmaPrlVersion.
- bug 933588 - B2G NFC: Rewrite NFC Worker in C++.
- bug 989834 - It takes 10 seconds to unload wifi driver on Sora
- bug 980701 - [B2G][Gaia][System][Buri] The proximity sensor activates unnecessarily when not in a call causing glitchy behavior.
- bug 949675 - Support HTTP->Rtsp Channel redirects.
- bug 975778 - [B2G] [Emulator] Support CDMA_FLASH command for Cdma call waiting and 3way calling scenario.

- bug 986365 - Crash in supplicant because of closing supplicant while waiting for event.
Firefox OS Systems - Front End (gwagner)
Firefox OS Systems - Platform (timdream)
- Back from a work week
- Big ticket items proposed for the next couple of trains:
- OMTC desktop (let's us simplify and remove some of the main thread compositing code)
- Skia content Windows (clear some way for the B2G and Android Skia content)
- APZ improvements (some architectural, some performance, some usability)
- v-sync on B2G (smooth scrolling, more consistent scrolling speed)
- Cloud Services work-week last week in MV
- Please keep testing Sync on Desktop
- Compiler (JIT)
- bug 989011 bug 989204 : Landed arrow function patches
- Garbage Collection
- NOTE: We are aware there are many crashes in Nightly. We are working to stamp those out quickly. If the crash stats (and performance) are not
back in line by the week before uplift, we will disable GGC for this cycle. Note, b2g and mobile are still building non-ggc, so the non-ggc paths are still getting actively tested.
- Front End and Other
- bug 992998: Run jit-tests in spidermonkey builds again, bug 992998
- bug 813366: Gracefully fail instead of crashing in some Yarr OOM situations
- bug 878399: toString / toSource for asm.js modules and functions.
- Speed: Made progress on the remaining issues for bug 931668 in 台北 two weeks ago. This eliminates the per-descendant cost of many (but not all) style changes of noninherited properties, though a bunch of "interesting" cases disable the optimization.
- Speed: bug 950526 landed on inbound yesterday; this avoids reconstructing text runs for style changes to text frames that don't require this work
- Test Coverage (for Speed): bug 964646 changed off-main-thread (OMT) Animations from having very little test coverage to actually having some decent test coverage, though more is still needed
- New Web Feature: bug 985838 changed the syntax for CSS Custom Properties for Cascading Variables (a.k.a. CSS Variables) from a "var-" prefix to a "--" prefix, and bug 957833 enabled CSS variables by default for all release builds so that they should ship in Firefox 31 unless something changes
- echo cancellation in getUserMedia bug 694814 is landing and bouncing for multiple b2g-emulator issues (none of which are bugs in the patches). See m.d.platform for discussion. tl;dr: b2g emulator sucks perf-wise and that messes up classes of tests.
- emulator is an unending source of pain. Cost us most of a week for two people already on this alone
- This will enable noise suppression by default as a trial.
- Next steps are to refactor the MediaStreamGraph to change all the time units and reclock based on the output clock. padenot is working on this
- Necko will be reporting incomplete downloads as errors (bug 237623). This is so the Download Manager can detect incomplete downloads, but will affect other clients too.
- The necko bits to make off-main-thread Websockets work are landed (bug 925623). Now we need the DOM work to make websockets in workers use it.
- Decided (with gfx, others) to mostly ignore small OS X 10.6 regressions.
- Addon manager: quicker startup block of addon compatibility check bug 760356
- Telemetry dashboard: ability to see own jobs logs and data, added google analytics.
- Stopped working and filing power usage bugs (took a ~month). Facebook uses more power on Firefox than other browsers bug 962594. How to address?
- Talos profiling - still failing on windows. Still being worked on.
- Session restore: talos test being finalized. Planning optimizations.
- asyncCopy working on fully off main thread.
- Async test errors: harness now treats uncaught async exceptions as errors, now fixing tests.
- Working with fx team to unblock australis regressions (linux keyhole).
- jmaher started filing regressions, big question: what to do about them? acceptance threshold, etc.
- mozpkix, our new certificate validation library, is on in Nightly! Please consider helping us by testing it or reviewing the code. See the announcement on dev-tech-crypto for details.
- Bug 971341, a nasty bug that prevented users from accessing pages with invalid CSP's, was fixed in Nightly and uplifted to Aurora and Beta.
- No update this week.
(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)
- Kyle Huey, Ben Kelly, Andrew McCreight and Nathan Froyd did some great work tracking down and fixing some slow B2G leaks.
- Past week's OrangeFactor: 11.88 (Previous Week: 8.86).
- Steady progress being made on Cedar getting mochitest-bc running in chunks with devtools in a separate test suite on all platforms. Hoping to get it in production by the end of the week.
- 13 intermittent failures fixed in the last week - List - Thanks!.
- Overall numbers look good for beta and release, the nightly and aurora issues are known and tracked.
(Comments and questions that arise during the course of the meeting or otherwise do not have a section.)
- Microsoft is EOL'ing Windows XP this week: https://www.microsoft.com/en-us/windows/enterprise/end-of-support.aspx
- Proposal: Move Thunderbird and SeaMonkey to mozilla-central: https://groups.google.com/forum/#!topic/mozilla.dev.platform/P8oHKTCWSiQ
