Platform/2011-Q4-Goals

General Goals

• https://intranet.mozilla.org/2011Q4Goals#Release_Engineering

Accessibility

• draft - canvas accessibility
• draft - tree creation performance and dom tree alignment
• draft - accessibility enabled on FF android builds

Perf

• Valgrind developer ROM for pandaboard or Nexus S
• linux "perf"-counters in zippity(depends on above ROM to have perf support in kernel)
• Bug 662444: exit(0) "immediate" shutdown prototype and a plan to land it
• Bug 686805: Incremental decompression for libxul on Android
• Startup-ordered binary on Windows
• 0 fennec sqlite fsyncs on first startup

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] Implement high-resolution platform timers
  • Fix bug 676349, Implement high-resolution platform timers for Windows.
• [ON TRACK] Improve dual-stack IPv6 experience for users.
  • Fix bug 684893, Re-implement "happy eyeballs" IPv6 autodetection at TCP open, or similar system.
    • Investigate a fix for biesi's patch
    • If too complicated, start coding the algorithm by the spec
• [ON TRACK] Have full implementation of current WebSockets spec (hopefully final) implemented and in the tree in a shippable state.
  • 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.
• [ON TRACK] Land and be prepared to ship Patrick's pipelining improvements.
  • Complete performance framework for evaluating them.
• [ON TRACK] Land SPDY implementation, bug 528288. OK if it remains pref'd off.
• [ON TRACK] Work towards an effective mobile disk cache implementation.
  • Create system with which to measure cache performance locally.
    • Some microbenchmarks have been set up; WIP to analyze and understand results. See Necko/MobileCache/MicroBenchmarks for status
    • WIP for a test-driver to fetch whole pagesets (much like Talos, but necko-only)
  • Use telemetry to collect cache performance data.
    • Some telemetry is in place; investigating how to use data from telemetry in microbenchmarks
  • Create a plan for a mobile disk cache based on that data
• [ON TRACK] Improve App Cache
  • resolve bug 538595
  • resolve bug 538588

Mobile

• NPAPI/Flash on Honeycomb integration and support
• Native front end prototype

B2G

• Gingerbread ROM with symbols for Galaxy S2 for Android Firefox debugging
• B2G ROM that can be used to build a basic phone (phone, contacts, vibrator, wifi, lock screen, etc).
• Basic Phone UI (Gaia) for B2G that can be used as primary phone for Mozilla developers

Research

• Rust: Release version 0.1
• Servo: Make DOM.js complete enough to run jQuery
• TC39: Implement modules in SpiderMonkey
• GPU Research: Investigate WebGL Video decoding
