Blocker Report

Gecko 1.9.2 / Namoroka

Browser / Front End

  • see our active projects and get involved / propose others
    • multitouch JS API prototype work (see proposed DOM events)
    • identifying places where animation in the browser would help the UX (blog post coming)
    • new UI mechanism for application notifications (see the spec)
    • struck a team to evaluate if it will be possible to integrate Personas for Firefox 3.6
    • meeting with the JetPack team to discuss how to build Firefox in ways that help them (providing APIs, etc)
    • also looking at protecting users with out of date plugins, see our current ideas
    • also looking at Ts and Tsnap priorities

GFX Update

  • Decode-on-draw is getting close to review-worthy. bug 435296
  • Mark Steele starting work on WebGL implementation.
    • Updating Vlad's work with new spec changes - native arrays

Layout Update

  • 24 open blocking1.9.2+ bugs in Layout
    • 7 are regressions from ireflow (there's also 1 in Widget)
    • 1 is a regression from compositor phase 1 (there's also 1 in Plugins)
  • dholbert making progress on code to be shared between SMIL animation of CSS and CSS transitions (bug 504652)
  • first parts of zwol's frame poisoning work now landed on mozilla-central (but not the main patch) (bug 497495)
  • roc's scroll optimization patch landed on mozilla-central and 1.9.2 (bug 507334)

Content Update

  • 1.9.2:
    • 13 open blocking1.9.2+ bugs in Content
    • 12 nominations, will triage...
  • Investigating twitter bug bug 510985.
  • Making progress on multi process networking.
  • peterv is making progress on ibench numbers, but not clear how heavily to invest there.
  • HTML5 parser work ongoing, including some 1.9.2 blockers there.
  • First pass at a Jetpack security model done.

Platform-specific Support Update

  • Good progress on 64-bit Mac OS X builds. Once patch for bug 435041 lands, only remaining work is complex text input (masayuki) and Cocoa printing (mstange).
  • Gecko1.9.2/Firefox3.6 and Java for Mac OS X: There is currently no Java plugin for Firefox 3.6 on Mac OS X due to the removal of OJI, LiveConnect, and XPCOM plugin support. JEP requires those components. A new Java plugin is due to be released within a month which will be compatible with Firefox 3.6.

    • Details of other ongoing work available on my weekly update blog post and on the project wiki.




  • Close to having necko IPC protocol hooked up and initialized
  • Some high-level design progress (from conversation with BZ)
    • IPC probably "main chrome thread <-> content process", not "Socket transport thread <-> content process"
    • Probably use "if(ContentProcess)" within existing necko code, rather than create new set of classes for Content-side necko.
  • Issue: which protocols (network; file?) need IPC?
  • Issue: goodbye standalone necko?
  • Set up design discussion for workweek


  • NPStream implementation uncovered some nasty race conditions... discussion ongoing in mdt.dom and chromium-dev
  • It's at least clear that prior run-to-completion behavior within the plugin itself will no longer be true


  • joe still working on tilebrowser graphics: ETA undetermined
  • need basic graphics before people can really start working on events

    • Answer: all drivers, not just endgame drivers
  • should we mark the set of bugs that are fixed on mozilla-1.9.2 by virtue of branching as fixed1.9.2+ (beltzner)
