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.)

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.)

App Tools (prouget)

<Read Only>

• FxOS Simulators 1.4 and 1.5 are now parts of the build system (not built manually anymore)
• network monitor now works with FxOS
• Developer HUD now supports certified apps and includes memory widgets and CSP errors
• Gaia tests now instrument the devtools actors
• Preferences (about:config) actor has landed
• Fennec tabs support has landed

GFX (milan)

• 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)

Layout (jet/dbaron)

<Read Only>

• 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

WebAPI (overholt)

• No update this week.

Quality Programs

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

MemShrink (njn)

• Kyle Huey, Ben Kelly, Andrew McCreight and Nathan Froyd did some great work tracking down and fixing some slow B2G leaks.

Roundtable

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

<Read only beyond this point>

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.)
