GFX Update

  • Pixman update landed on mozilla-central, and gave us a win on Tsvg, bu most importantly it gave us a whole lot of code churn, and therefore a new set of bugs. Please test!
  • Cairo update work is ongoing. (This will allow us to use the cairo GL backend.)
  • The Cairo side of the Direct2D patch has landed. Font, widget, etc work is still undergoing review.
  • Core Animation patch (bug 497225) is undergoing review. It has some deficiencies that we hope are fixable, but might not be. There also seems to be no way to retrieve, and therefore test, its output (confirmed by an Apple employee).

Layout Update

  • Plans laid for adaptive streaming at FOMS
  • Landed syncbase timing for SVG animation

Content Update

  • CPOWs still awaiting review (bent, feel free to steal SR from bsmedberg). Exception support in a followup bug. Coordinated with cjones to support automatic run-to-completion semantics.
  • More people on board with e10s necko work
  • Starting to help out with triaging for trunk alpha.
  • Complete wrapperization ready for review.
  • Talos now fixed so its pageset works with HTML5 parser builds.
  • Main HTML5 parser mochitest failure reason identified.

  • Last known blockers to on-by-default should land today, hopefully on-by-default for tomorrow's nightly (bsmedberg will blog today)
  • small set of additional blockers for beta, plus actually doing the backport. The tree is now live and working

Fennec-related work:

  • async global history (Fred)
  • networking (bsmedberg owes jduell a review)
  • event handling (smaug)


  • DWARF Linux support landed.
  • DWARF CFI parser written, tests.
  • Remaining work:
    • Unit tests for DWARF-CFI-to-Breakpad-STACK-CFI adapter. This is a small component; tests should be done today.
    • Various cleanups. No big stuff: Google C++ Style guide compliance points, etc.
    • Getting Google to review the patches. (Some of them are big.)

Tree Management

Will evaluate results after a week or two.

  • Started move of n810s to faraday cage. bug 538523
