Developer Tools

• [MISSED] Land Highlighter

These are all close, demo well, and a couple pieces have already landed, but we're not counting "close" here, and they aren't done. Ergo->MISS.

  • Complete bug 651693
• [ON TRACK] Azure - Cairo 2D canvas implementation
  • Land on mozilla-central by Sept 13 preffed on
• Other important Q3 work
  • Start using telemetry
  • Windows 7 font rendering
  • WebGL improvements
    • CORS support, finalize 1.0
    • Anti-aliasing
    • Ongoing security improvements

Layout

• [ON TRACK] CSS 3D transforms on mozilla-central
• [ON TRACK] CSS Ruby on mozilla-central
• [ON TRACK] fullscreen style-system support on mozilla-central

• [ON TRACK] no threads used for paused media elements
• [ON TRACK] Media URI Fragment support

DOM

• [ON TRACK] e10s:ify IndexedDB
• [ON TRACK] Replace xpidl with a python based version
• [ON TRACK] Start collecting telemetry data for the DOM (number of JS wrappers per document, etc)
• [ON TRACK] Pre-cached JS libraries (not sure what the goal would be here)
• [ON TRACK] Support whole directory upload
• [ON TRACK] File API support in Workers
• [ON TRACK] Finish up the NodeList bindings

• [ON TRACK] Implement support for <input type "number">, carryover from last quarter
• [ON TRACK] JS Compartment per global
• [ON TRACK] Remove support for policy prefs in caps (significant code removal, dependes on JS compartment per global)

JS

• [ON TRACK] IonMonkey working prototype. This means a working compiler with GVN, LICM, inlining, LSRA, and on-stack replacement for a subset of JS that at least includes arrays and properties.
• [ON TRACK] Debug API: land new debug API through to mozilla-beta
• [ON TRACK] GC: finish incremental GC, start generational GC

Accessibility

• [ON TRACK] Telemetry [bug 648121]
• [ON TRACK] E10S [bug 646596]
• Other important Q3 work:
  • Fennec Android accessibility
  • Make NVDA screen reader users happier [bug 659863]
  • Crush a11y oranges User:Ehsan/OrangeCrush

Perf

• [ON TRACK] Valgrind on android
• [ON TRACK] Instrument at least 90% of Firefox IO with Telemetry
• Other important Q3 work:
  • Shutdown telemetry
  • Evangelizing telemetry
  • Implementing telemetry probes for the metrics team

Networking

• [ON TRACK] SSL performance and responsiveness improvements. Also important for other projects like SPDY.
  • Fix bug 511393, Allow multiple SSL worker threads.
• [ON TRACK] Start making use of telementry to collect network performance data.
  • Fix bug 658894, Collect basic telemetry for HTTP requests and page load.
  • Fix bug 662555, Race condition when measuring requestEnd.
  • Fix bug 539093, Implement high-resolution platform timers for Tier I platforms.
• [DONE] Improve dual-stack IPv6 experience for users.
  • Fix bug 621558, Implement "happy eyeballs" IPv6 autodetection at TCP open, or similar system.
• [ON TRACK] Keep WebSockets implementation up to date with latest spec drafts.
  • We can't control when the spec is complete enough to ship but we can follow it closely and be ready to ship as soon as possible.
  • Ship an implementation (possible prefixed if spec is not ready) in Firefox 7.
• [ON TRACK] Improvements to NeckoNet, our standalone networking performance testing tool.
  • Should allow us to compare networking performance between two builds under various conditions, including:
    • the ability to adjust latency
    • the ability to adjust random packet loss
    • the ability to turn on loss of the first SYN of a flow
  • Ensure that the test server supports pipelining
  • Allow testing against NeckoNet from Windows and Mac OS X
• [ON TRACK] Make progress with pipelining improvements.
  • Review outstanding HTTP pipelining improvements. This means being able to mark the review-tracking bug 659760 as fixed.
  • Complete performance framework for evaluating them.
• [ON TRACK] Make progress on an SPDY implementation, bug 528288.
  • Hard to say what we might be able to accomplish over the course of three months, but we want to have an implementation in progress.
• [ON TRACK] Work towards an effective mobile disk cache implementation.
  • Create system with which to measure cache performance locally.
  • Use telemetry to collect cache performance data.
  • Create a plan for a mobile disk cache based on that data
• [ON TRACK] Fix bug 666059. Only use memory cache for private browsing so that leaving private browsing mode doesn't necessitate blowing away the cache.
• [ON TRACK] Fix bug 670911. Make deleting the disk cache not kill responsiveness and hog i/o. Do it on a thread, perhaps throttled so as to not hog i/o bandwidth.
