Firefox 3.0.16 / Firefox 3.5.6

Firefox 3.6 Beta

  • Released on Friday, Oct 30th
  • plan is to promote it heavily to rapidly increase beta audience
  • will refresh frequently via the Firefox 3.6 beta update channel, each update will be versioned "3.6b#" and presented as a "revision"
  • next update is aimed to be this Friday, minimally containing:
    • DLL component directory lockdown and blacklisting patch (see bug 524904 and bug 519357 (blocklist policy discussion in bug 525103)
    • syntax changes for CSS gradients (see bug 513395)
    • cycle-collector patch to stop cycle collection instead of crashing (see bug 521750)
    • other changes on mozilla-1.9.2 since we froze for beta

Firefox 3.6 Release Candidate

  • proposed code freeze November 18th (2 weeks)
  • proposed release November 26th (Happy Thanksgiving)
  • need to check these schedules with build and QA, obviously

Blocker Report

See more Firefox 3.6 related blocker queries, or learn about the new status and blocker flags

Browser / Front End

(Progress reports every weekend on Planet Firefox)

  • see our active projects and get involved / propose others
  • Namoroka/mozilla-1.9.2 front end development:
    • 29 blockers left, 7 are crashkill
    • team estimates this number will be 10 by end of the week
    • per tab prioritization for session restore bug 514490 causing test failures on mozilla-central, should be wrapped up today or tomorrow, see the project page for more detail
    • windows 7 aero peek per-tab preview: as per bug 525475 we're going to pref this off by default until the other bugs are fixed, allowing us to unblock on them

GFX Update

  • 18 blockers
    • 9 are FIXED, several have patches.
    • GFX team will be triaging these to see which absolutely need to block.
    • Looks good for a November 18 freeze date.
  • 3.5.4 crashes
    • We discovered once 3.5.4 had been released that we had caused two topcrashes: bug 524462 and bug 525326. These were fallout from security bug fixes.
    • More testcases helps, and we're adding more. But the nature of graphics code (handling user-provided data) implies that it's very difficult to have fully complete test suites.
    • It's very likely that these could have been caught in a beta period for 3.5.4. Since we already look at crash-stats, should we just extend beta periods? Should we make it part of the "new release" signoff that we haven't introduced new topcrashes?
  • GFX team focusing on blockers, Electrolysis, crashes, and performance.

Layout Update

  • Blocker report:
    • 18 blockers, but mostly (9) fixed on trunk and need 1.9.2 landing, or have patches, or we're not sure there's a bug
    • Silverlight issue fixed after conversation with Microsoft --- we're doing a trivial workaround for them calling NPN_Invalidate for a windowed plugin
    • Only 1 bug where we know there's a bug and we don't have a patch (519767)
    • 1 untriaged layout nom
  • CSS gradient syntax change (bug 513395) landed on m-c yesterday; backport to 1.9.2 is posted to the bug, the a1.9.2 queue, and the try server; would like to land it tonight or Wednesday morning assuming all is well
  • Layers API developed: Implementation to proceed shortly. Send feedback.
    • Framework for hardware acceleration, 3D transforms, retained buffers for elements, cross-process rendering, off-main-thread compositing, animation and video playback
  • Patches ready to remove nsIScrollableView on trunk
  • Jonathan Kew in Toronto office this week
  • WOFF getting lots of press
  • Rapturous reception at AtypI

Content Update

  • Excellent work by bz and smaug on a 1.9.1 stability regression
  • Working on 1.9.2 blockers (26 total, 5 fixed/dup, 7 crashkill)
  • crashkill work
  • HTML5 parser work moving forward, getting through reviews.

Platform-specific Support Update

  • (smichaud) 1.9.2/JEP update -- No new bugs in last week. No blockers.


Startup Performance

  • Almost done with a tool that shows numbers for all Talos tests across all branches for all platforms, summarizing median and mean per platform, including weekly difference, and difference from Firefox 3.5.
  • Found a scenario for stable cold startup numbers on Windows. Next step is to get a Talos patch up, and work with Rel/Eng to get it deployed into testing so we can see numbers on real Talos boxes.
  • Rob Strong split up the update service in bug 311965, has most reviews (affects all toolkit apps) and is about ready to land. This showed a significant win on WinCE startup.
  • Taras and Joel are working on bug 524202, tracking down exactly how and when dynamic library code is loaded. See this comment for a good summary of the issue.
