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)

CritSmash (dbolter)

MemShrink (njn)

<Read Only> No update.


Stability (kairo)

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.)

A*Team (jgriffin)

Accessibility (dbolter)

B2G Services (dougt)

Cloud Services (mmayo)

Desktop Platform (bsmedberg)

Developer Services (gps/lthomson)

Developer Tools (prouget)

DOM (jst/overholt)

Electrolysis (e10s) (blassey)

Firefox Desktop (gavin)

Firefox Mobile (snorp/blassey/mfinkle)

GFX (milan)

  • B2G: the follow up to 2.1 ("2.X") looks to be based on Gecko 37...
    • Graphics plans are unchanged from 2.2 to 2.X
    • Graphics plans were based on Gecko 38
    • So... will likely keep the 38 time frame and uplift to B2G 37 branch past the trunk. Will figure it out by mid January when this becomes relevant.

JS (naveed)

  • Work Week
    • Shumway load time is highest priority
    • 2015 Planning (more on this to come)

Layout (jet/dbaron)

<Read Only>

  • Investigating bug 1107378 to fix webkit-dependent sites in China added to a mobile (fennec) fix-list.
  • Landed bug 1089417 - restyling fixes for CSS media queries

Media (mreavy)

<Read Only>

  • 1. What has your team done since last week that might impact others?
    • Hello is in Release/34! Early reviews are generally good (and recognize the differences for privacy compared to say Skype).
    • Landed sdparta! bug 1091242 - (rewrite of the majority of webrtc signaling, other than the parsing).
      • Known regression bug 1109130 breaks < MSVC 2013 compiles; fix shortly
    • Lots of great discussions at #mozlandia
    • FoxEye presentation (echoes of roc's older MediaStream Processing proposal)
    • Work moving forward towards multiple streams of a type and renegotiation
  • 2. What will your team do this week that might impact others?
    • Starting work towards a webrtc.org update
    • More sdparta work


Necko (dougt/jduell)

Performance (vladan)

1. What has your team done since last week that might impact others?

  • bug 1107779, bug 1107782: Avi found that the "activeTicks" FHR measurement significantly over-reports Firefox usage time, because Firefox fires "user-interaction-active" notifications while the mouse cursor is positioned over the browser even when the user is away from the computer
    • Should we just land the fix, or is it important to maintain continuity with the current measurement (for monitoring for relative changes)?
    • The above bugs are unrelated to the big drop in activeTicks reported in bug 1096498
  • Talos numbers for most E10s tests are available
    • we're still converting some tests, e.g. tresize
    • there are serious regressions from E10S, e.g. WebGL is 4x worse on Windows
    • Joel Maher said he'll write a blog post summarizing Talos regressions/improvements from E10S
  • Spark is the new, much faster way of analyzing large amounts of Telemetry data:

2. What will your team do this week that might impact others?

  • bug 998863: Almost ready to land asynchronous initialization of out-of-process plugins

3. Is anything slowing your team down or getting in their way?

  • bug 998863: Need one more review for asynchronous initialization of out-of-process plugins

Seceng (dougt)

Shumway (tschneidereit)

WebAPI (overholt)

Roundtable

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

Touch input standardization update (mbrubeck)

  • W3C Pointer Events going to Proposed Rec. Shipping in IE, portions shipping in Chrome, partially implemented in Gecko.
    • Chrome and Safari have no plans to ship full Pointer Events implementation.
  • Touch Events CG is actively discussing errata and extensions, about to start a weekly-ish telecon. Let me know if you want to get involved.
  • Gecko/Touch has a breakdown of our implementation status and various missing pieces.
