  • also looking at Ts and Tsnap priorities

GFX Update

• Decode-on-draw is getting close to review-worthy. bug 435296
• Mark Steele starting work on WebGL implementation.
  • Updating Vlad's work with new spec changes - native arrays

Layout Update

• 24 open blocking1.9.2+ bugs in Layout
  • 7 are regressions from ireflow (there's also 1 in Widget)
  • 1 is a regression from compositor phase 1 (there's also 1 in Plugins)
• dholbert making progress on code to be shared between SMIL animation of CSS and CSS transitions (bug 504652)

Content Update

• 1.9.2:
  • 13 open blocking1.9.2+ bugs in Content
  • 12 nominations, will triage...
• Investigating twitter bug bug 510985.
• Making progress on multi process networking.
• peterv is making progress on ibench numbers, but not clear how heavily to invest there.
• HTML5 parser work ongoing, including some 1.9.2 blockers there.
• First pass at a Jetpack security model done.

Platform-specific Support Update

• Good progress on 64-bit Mac OS X builds. Once patch for bug 435041 lands, only remaining work is complex text input (masayuki) and Cocoa printing (mstange).
• Gecko1.9.2/Firefox3.6 and Java for Mac OS X: There is currently no Java plugin for Firefox 3.6 on Mac OS X due to the removal of OJI, LiveConnect, and XPCOM plugin support. JEP requires those components. A new Java plugin is due to be released within a month which will be compatible with Firefox 3.6.

• JS trace tests refactored
• large parts of nanojit merge complete

Startup Performance

• Joel
  • read up on previous optimization efforts and will start running Firefox in Shark very shortly.
• Taras
  • landed mmap jar io (bug 504864), combined startup jars (bug 468011). Looks like decent Talos improvements across the board.
  • Working on moving res/ stuff to a jar bug 508421
  • Up next, moving app prefs into jars bug 507288, optimize jar io further bug 510611, etc
• Drew

• Dietrich
  • Enabling PGO for SQLite, mozStorage and Places code on m-c this week
  • Got JS components joined (thanks to some help from fqueze), testing now for perf effect
  • Dirty profile testing being enabled this week by Alice, testing two different Places profiles. More coming - send suggestions of dirty testing to me
  • Details of other ongoing work available on my weekly update blog post and on the project wiki.

Electrolysis

Necko:

• Close to having necko IPC protocol hooked up and initialized
• Some high-level design progress (from conversation with BZ)
  • IPC probably "main chrome thread <-> content process", not "Socket transport thread <-> content process"
  • Probably use "if(ContentProcess)" within existing necko code, rather than create new set of classes for Content-side necko.
• Issue: which protocols (network; file?) need IPC?
• Issue: goodbye standalone necko?
• Set up design discussion for workweek

Plugins:

• NPStream implementation uncovered some nasty race conditions... discussion ongoing in mdt.dom and chromium-dev
• It's at least clear that prior run-to-completion behavior within the plugin itself will no longer be true

Fennelectrolysis:

• joe still working on tilebrowser graphics: ETA undetermined
• need basic graphics before people can really start working on events

Tree Management

• TB2.0.0.23 this week
• Turned off TP3, fast-talos machines yesterday.
  • yeaaaah for faster, newer, TP4!
• New dirty-profile talos suite coming later this week.
• l10n nightly updates on mozilla-central as of Sunday night (16th).
  • users on nightly before 16th need to manually pave-over-install like usual
  • working on getting l10n nightly updates on 1.9.2
• WinCE build-on-checkin now on mozilla-central, mozilla-192
  • no unittests, talos
• proposed changes to fennec linux-arm unittest/talos jobs
  • run desktop unittests during the day, on n810s at night
  • will add another 20 n810s to the (tiny) pool, and revisit.

Roundtable

• Project metrics charts (timr)
  • 1.9.2/3.6 snapshots: Blockers and nominations.
  • 1.9.2/3.6 blocker and nominations trends
  • These are automatically updated every morning before 6am Pacific time
• Who is allowed to mark approval1.9.2+ ? (dbaron)
  • Answer: all drivers, not just endgame drivers
• should we mark the set of bugs that are fixed on mozilla-1.9.2 by virtue of branching as fixed1.9.2+ (beltzner)
  • Core/Toolkit/Firefox: 6034 bugs FIXED since Dec-01-2008 and Aug-13-2009 (warning: takes a while to load)
  • this would miss some NSS and NSPR bugs, but they're harder to query
  • it would also cause a good deal of bugspam :)
