From MozillaWiki

• Video, roc/cdouble:
• Compositor, roc:
• Worker Threads, bent:
  • Moving along well, was blocked by a few JSeng and XPConnect bugs but now all known problems resolved (thanks brendan, jst, jorendorff!).
  • Arun and Sicking helping with API design discussion.
  • Johnny recommended an arch change to avoid future XPConnect bugs that will take a day or so.
• JS Tracing, brendan:
• Acid3, dbaron:
  • All the bugs that we need to fixed have been analyzed.
  • There’s still a good bit of work to do on some of the bugs.
  • A bunch at risk.
  • SMIL @ risk, SVG fonts at risk.
  • roc has patches for all the layout bugs.
• Protected/Low Rights Mode, mconnor/jim:
• SVG CSS, roc:
• CSS transforms – keith (dholbert’s intern): Started two days ago, so probably not much progress here.  🙂
• pixman/cairo perf, vlad: Out this week. Last status:
  • we’ve got stuff coming from antoine/fred
  • will turn on SSE opts
  • will need ARM stuff
• offline, dcamp: Working with honzab implementing remaining features in the offline spec (versioned app caches, fallback uris)

1.9.1 Discussion

• mozilla-central status? How are things going? Bumps in the road? Easy? Complaints or suggestions?
  • Need a guilty list. John O has a bug for this. (bug 419949)
  • Need a query facility, like bonsai.
  • Cycle times are seemingly slower on moz-central (about an hour slower). Need to look into this. John O to investigate.
• graph server changes:
  • http://tinderbox.mozilla.org/showbuilds.cgi?tree=MozillaTest
  • when to move into production
  • break old links in bugs
• Major progress, wanted1.9.1+ bugs that are in trouble?
  • Layout 1.9.1 Update:
  • Content 1.9.1 Update:
  • GFX 1.9.1
    • Only one blocking1.9.1+ bug, but several wanted1.9.1+
    • A worrying number of wanted1.9.1+ assigned to Joe Drew, but most of them are highly related
      • Do we have an update on SVG fonts and/or bz’s work to make <img src=”foo.svg> possible?
    • Two still assigned to nobody
    • Vlad, Stuart off for another week and a half (roughly). JOEDREW! off next week and 1/2 of the week after.
  • JS 1.9.1 Starting to land stuff that missed Fx3, mostly perf and conformance bugs. Strategy for performance improvements:
    • gradual codegen evolution with the aim of less dispatch overhead, Acid 3 bug (dmandelin/shaver)
    • JSObject ops makeover
    • direct threaded interpreter loop on Windows
    • SDK / compiler adjustments on Mac
    • Profile guided input improvements

Followups

• opening mozilla-central for general checkins is tracking bug 422754
  • daily meetings – unit-test failures are possibly VM loading issues or some difference between different VMs – for the moment, we’re moving some known-good machines from Firefox
  • bhearsum working on codesize test… some assumptions have changed
  • performance regression was a fluke… a clobber fixed it 🙁
• Consolidated post-1.9 planning wiki pages are pending. Damons is merging the work week spreadsheets into a single location tbd.

Status Reports

• jimb
• dmandelin
• taras
  • bug 432915 push/pop stuff

Discussion Topics

Actionmonkey performance measurements and MMgc fixup: status and plan of attack.

• ignore incremental for the moment, since we can’t use it with the cycle collector anyway?
• stats on PR_Lock taking a long time?

Wins:

• tune GC-from-alloc
• per-thread freelists
• mochitest crash
• general profiling
• MMgc debug performance
• 64bit
• maybe valgrind

Getting jimb unstuck on TC-MMGC to work on other things…

Purpose of this meeting (general, or just tamarin, MMgc, code rewriting, etc.)

Getting mobile into hg?
