Platform/2008-Q4-Goals

XPCOM+XPConnect

• Map out allocator strategy: if XPCOMGC+Boehm, then:
  • Fragementation improvements in Boehm allocator
  • Make spidermonkey use the new GC
  • Make content GCed instead of refcounted, remove cycle-collector, and make xpconnect aware of GCed nodes (probably longer than a 3-month goal)

Layout

• Double down on wanted1.9.1/blocking1.9.1 bug list
  • Regressions
  • Security bugs
  • Performance hotspots
  • All 1.9.1 blockers marked blocking before December fixed by end of December
• Linux support for CSS downloadable fonts
• Land and stabilize support for external resource documents
• Plan post-1.9.1 feature set

GFX

• Performance
  • Create plan for hardware graphics acceleration
  • Optimize mobile performance for high user perf on next-gen devices

• Capabilities
  • Experimental builds with access to more OpenType and other low-level features
  • Have decode-on-draw option for image rendering
  • Draft of Canvas 3D OpenGL API spec

Mac OS X

• Finish Mac OS X platform blockers for Gecko 1.9.1.
• Complete specification for plugin event handling which will allow plugins to not eat events they don't handle (bug 78414). Spec should cover windowed and windowless plugins.
• Make decisions about PPC and Mac OS X 10.4 support post-1.9.1.
• Make significant progress towards an NPAPI testing framework.
• Make significant progress towards a Cocoa NPAPI event model implementation.
• Make significant progress towards 64-bit readiness.

Content

• Support Firefox 3.1 ship
• Major DOM performance improvements
  • Fast JS JIT->DOM calls for performance critical methods
  • innerHTML perf improvments
  • Stake out off-main thread HTML parsing work
• Tie up loose ends from previous releases
  • Fix nsIDocument::GetScriptGlobalObject() properly
  • Cycle collection sanitizing (inner/outer window lifetime cleanup, docshell cycle collection, delayed window collection regression tests)
  • Make XHR (*not* crossite related) spec compliant
• Misc
  • Eliminate notification batching in the content sinks (jonas)

JS

• tracing: no known regressions and on by default
• regex: substantial perf improvement ( > 2x)
• tracing: recursion

Toolkit

• Process-per-tab/Windows protected mode...?

Build System

• Finish the spidermonkey standalone build system
• Get the spidermonkey unit tests running as part of TUnit
• hgweb improvements?

Static Analysis

• Aggregate dead code data from mac/linux/windows and present it via html reports with links to relevant sourcecode.
• Setup dehydra buildbots on mac/linux
• Produce debian packages for pluginified gcc + dehydra
