Browser / Front End

(Progress reports every weekend on Planet Firefox)

  • see our active projects and get involved / propose others
  • Namoroka/mozilla-1.9.2 front end development:
    • 21 blockers left, 7 are crashkill, 7 need patches
    • not including crashkill and review-waiting, we’re below 10 and will keep it there
    • per tab prioritization for session restore bug 514490 landed
    • windows 7 aero peek per-tab preview is now preffed-off as per bug 525475

GFX Update

  • 13 blockers (-5 w/w)
    • Long poles right now are imagelib bugs (needs review from someone who knows imagelib) and a couple of Linux bugs (which have no patches yet).
  • 5 nominations
    • All annotated with should block/should not block in whiteboard; need a driver to make the final call.
  • Jeff is starting work on one of our quarterly goals, a scrolling interactivity benchmark. You can follow along in bug 527728.
  • Bas has built upon his DirectWrite font backend, bug 517642, with a Direct2D cairo backend, bug 527707.
    • Direct2D is a hardware-accelerated, quite Cairo-like API for Windows 7/Windows Vista, and it interoperates with Direct3D too.
    • The Direct2D backend depends on DirectWrite for fonts because GDI can’t write to hardware-accelerated contexts.
    • This will be our second hardware-accelerated Cairo backend, after the OpenGL/DirectDraw backend used on the Tegra devices.
    • Along with DirectWrite, Microsoft has backported Direct2D to Windows Vista.
  • Rob’s still working on the bug reports that have resulted in us turning Aero Peek off in 3.6.
  • Jim’s got an initial, prototype patch for cross-process windowless plugins on Windows. bug 522299
  • Mark’s WebGL implementation still coming along well.
    • One issue is that WebGL arrays are different from JS arrays, and that can cause perf issues. Mark’s got some ideas.
  • Blockers, topcrashes, electrolysis, performance.

Layout Update

  • Blocker report
    • 1 nom (which will not block)
    • 7 Blockers:
      • 1 only needs branch landing (#501627)
      • 1 needs trunk and branch landing (#527306)
      • 1 needs review (#522787)
      • 1 has a patch, but maybe needs a better fix/to be reassigned (#525856)
      • 2 are frame poisoning improvements and probably should not block IMHO (#507294, #522088)
      • 1 is a crashkill bug that is still being researched, probably should not block IMHO (#492675)
  • N900 arrived!
  • [roc] failed to fix httpd.js GC issues, still no GC happening
  • VMWare record and replay much improved, still working on automation to help with orange analysis

Content Update

  • HTML5 parser update (hsivonen)
