GFX

• Benoit Girard landed async drawing for Core Graphics and Core Animation plugins on Mac OS X. (bug 598425)
  • Should provide a big perceived performance improvement when you have plugins on a page.
  • Brings OS X up to platform parity with Windows and Linux.
  • Please look for plugin drawing/performance regressions on OS X!

Layout

  • If you might want to use such an API, see bug 467669
• Zzzzz

Plugins

• Josh working on moving plugins to content, will allow display:none instances and re-parenting without restarting instances.

DOM

• nothing to add this week.

Network

• Should have Nick Hurley's standalone network test suite for Linux ready by next week. Will allow for adjusting latency, random packet loss, and "reproducible random" packet loss while replaying a browsing session.
• Tomorrow (June 8) is IPv6 test day. (It technically begins 6 hours after this meeting, at Midnight GMT.) Test, report bugs!

Multi-Process

• bsmedberg posted to dev.planning regarding plans about extension (and Firefox frontend) compatibility
• Felipe working on getting a running browser ifdef-ing off non-essential code

Tree Management

• Reducing test slave load
  • trychooser syntax will be required to reduce load. bug 649402
  • https://bugzilla.mozilla.org/show_bug.cgi?id=659328#c4 - determine which suites to merge
  • bug 661585 - a lot of setup time improvements; going to improve network connectivity between datacentres
  • You can help! We need help profiling test runs to see if there are ways to make them faster.
  • https://wiki.mozilla.org/ReleaseEngineering/BuildFaster

• migration from tp4 --> tp5 (bug 658392 and threads in dev.tree-management, dev.planning).
  • Rollout plan is still being worked out. Need to be careful to avoid increasing load on slaves, or disrupting faster release cadence (FF5.0, FF6.0...).

Stability Report

• Trunk ADUs around 47K.
• Top crash browser crash list for the trunk yesterday - https://crash-analysis.mozilla.com/chofmann/20110606/top-7.0a1.html

Roundtable

• Security bug triage is changing, the responsibility for suggesting security ratings for bugs is being shifted towards developers rather than the security group. (jst)
• MemShrink effort (initiated by Nicholas Nethercote) starting up on Tuesday next week (6/14) at 1pm pacific. Meeting details TBD. (jst)
