Platform/HTML5 parser tasks

This page outlines what needs to be done to ship a release with the HTML5 parser enabled by default.

Things that need to be done before shipping the HTML5 parser in a final Firefox release

• Fix "[HTML5]" bugs marked P2. (hsivonen)
  • 561874 The HTML5 parser needs limit DOM tree depth
    • Patch exists; needs testing.
  • Bugs waiting on Hixie or W3C WGs
    • 563526 Early U+0000 eats frameset (Can't configure D-Link DSL-G604T ADSL router)
    • 552908 Implement spec changes to SVG </a> and handling
      • Waiting for Hixie to resolve bugs discovered in the spec text while implementing this.
    • 552938 Implement the SVG load event in text/html
      • Time estimate: Less than a day, but waiting for the SVG WG to decide whether to remove this event instead.
    • 557197 &#13; in element content expands to CR and shows up as a non-collapsing space in layout
      • Preliminary layout patch exists. Waiting for the CSS WG to approve the solution or propose another solution.
• Reviews on patches
  • 565432 Higher layers are now responsible for ignoring space characters before URL in href (bzbarsky)
• Security review.
  • Talked to dveditz about how to do the security review for the HTML5 parser, and it's not clear what the best format for the review would be. But we did decide that it's not something we need to do before turning the parser on by default, but we need to do it before we ship it. --jst
• 544994Create a "slow tp" test suite for exercising speculative parsing. (bnewman)
  • What if this suite reveals something bad?

Suspended items that may re-enter the list of release blockers

• Suspended bugs that were previously P2
  • 482917 Make HTML5 parsing not regress stream data availability to extensions
    • There's now a patch but no way to test it.
    • Suspended, because there are no known extensions that use the API in question and are compatible with Firefox 3.6.
    • Time estimate: Unknown. (Need to find an extension that actually uses this. The alternative is writing an extension just for testing.)
