Notices / Schedule

Firefox Development

• See above, Firefox 5 shipped today!
• No dev update this week, it's been a bit of a distracting day.

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.

  • 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.

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...
  • Bug 663916
  • Bug 664504
