Firefox OS Systems - Front End (gwagner)

Firefox OS Systems - Platform (timdream)

GFX (milan)

  • Lots of vacations.
  • Siggraph last week. Nice summary from :nical on dev-tech-gfx. Extremely short summary: VR/AR, next gen GL, other.
  • Firefox OS:
    • Some last minute blockers. The biggest recent graphics bug turned out to be an intermittent, low level network/ipc issue, usually only showing up during multi-day partner testing. Currently looking at a couple of canvas issues, related to the updated version of Skia (back in March.)
  • Desktop:
    • Will try to get to final stage/land desktop tiling the week of September 22nd - probably behind a pref until APZ on desktop is available, to avoid performance issues. The aim is to have it (the tiling) stick in 35, but we may need to test with that pref enabled, to avoid regressions while APZ work is being done.
    • Back on the Skia content work, we were derailed by the Firefox OS blocking bugs.

JS (naveed)

<Read Only>

  • Compiler (JIT)
    • bug 1041781: Landed native to bytecode mapping

  • Garbage Collection
    • bug 650161: Landed first cut of compacting GC implementation (build with --enable-gccompacting to try it out)
    • bug 995284: Made GC behvaiour deterministic in shell builds
  • Front End and Other
    • bug 1052248: Tweak the goodAllocated heuristics for JS arrays
    • bug 1041688: acquired properties analysis working but has some regressions

Layout (jet/dbaron)

<Read Only>

  • caret cleanup landed (bug 1048752)

  • HTTP cache v2: some last bugs before we release: mostly tests but also a few real bugs (bug 1042192, bug 1054425, bug 660749)
  • minor fixups for HTTP2: we're close to being able to pref it on.

Performance (vladan)

  • bug 1045108: Please review your Telemetry probes and make sure they're still useful. Also please set the expiry dates for your probes (e.g. "expires_in_version": "never", or "35" for Firefox 35) -- we'll be automatically marking unclaimed probes for expiry in Firefox 40.
