Notices / Schedule

  • Firefox 5 shipped today (mobile and desktop, rock!)
  • Next source migration is July 5th
  • We'll have a post-mortem for the rapid release process next week, time TBD
  • We'll have a meeting about 3.6 EOL next week, time TBD

Firefox Development

  • See above, Firefox 5 shipped today!
  • No dev update this week, it's been a bit of a distracting day.
  • Spinning up a firefox team project branch, follow along at home! bug 663128

GFX

  • There are blog posts forthcoming, but we have recently changed the font rasterization method on Windows Vista/7 when using DirectWrite to make fonts "less fuzzy."
    • This change is now on mozilla-central, and we're hoping to land it in Aurora before too long.
    • Technical details: We're now using the GDI_CLASSIC DirectWrite rasterization method for the most common web fonts at smaller sizes. We believe this should resolve the most common problems without pessimizing downloadable fonts unjustly.
    • For more information, see bug 661471.

JS

  • Brian Hackett plans to land the type inference branch to TM shortly before the next mc->aurora merge.
    • JS changes that want to go out for Fx7 would land directly to mc during the time between the TI->TM merge and the TM->mc merge.
    • TM would merge to mc just after the mc->aurora merge for max bake time on nightly.
    • He is currently seeing a ~1.6x improvement on Kraken and 1.1-1.3x on V8-V6 (vs trunk).

Layout

  • Jonathan Kew's font inspector API landed. You can now write extensions that will tell you exactly what font(s) are being used to render any given DOM range --- including the entire document, or a single character. For downloaded fonts you can get metadata including the license.

Plugins

  • [josh] Bug 90268: Content ownership of plugin instances is mostly working on all platforms. Patch is on the holly branch. Need to fix remaining test failures and some to-do items before reviews can start. Can probably have that done and reviews started by the end of the week.

DOM

  • AddEventListenerByIID() n' friends is going away (sicking)

Network

  • [hurley] NeckoNet now available. Standalone test suite for networking. Can record and replay test pages with different builds against custom-configured networking conditions. Will be adding features and improving usability quickly.

Accessibility

Multi-Process

Tree Management

  • We have been running side by side tp4 and tp5
    • We would like to disable it next week on June 30th
    • comments/questions? bug 664831 - disable tp4 (except older release branches)

Stability Report

  • The overall crash numbers look good but the trunk has been a bit more variable than for FF5 and even FF6.
  • Weird spike yesterday due to a new signature - @0x12e117. All the reports appear to be dups so for now we are going to ignore this. It drove up the crash rate for a day (see graph).
  • 2 signatures that are not exactly new but have been at the top of the list for the past week or so...
  • New signature filed for 4.0.1 but present on other branches:

Roundtable

  • MemShrink effort up n' running, next meeting today at 1pm PDT. (jst)
  • Land aurora patches with approval and mark as appropriate
  • mozilla-inbound is not the new try server, it is not OK to land untested patches there! :) (ehsan)
