Notices / Schedule

  • We are here in the schedule
  • Beta 5 will go-to-build this evening PT (2/28). Please nominate/land any applicable bugs asap. If you have a bug currently nominated for mozilla-beta approval, please make sure to be available after today’s 2-3PM PT channel meeting to land approved bugs once we complete our discussions. Alternatively ping akeybl in IRC to expedite the process.

  • Code freeze for FF11 is this Friday (3/2).
  • Final sign-off for FF11 will be scheduled for next Wednesday (3/7). Details to be announced on dev-planning
  • Please see our Channels Triage queries to find tracked bugs for each release. Please let release-mgmt (@mozilla.com) know if any of these bugs no longer need to be tracked or need support from QA or the crash-kill team (for Socorro/crash-stats data).

Firefox Development

  • Marco Bonardo landed the livemarks re-write – this was a big chunk of work which has plenty of benefits, including no more synchronous IO, and less entanglement with the rest of places (bug 613588)

  • Paolo Amadini has flipped the default value of the “load tabs on demand” pref, which should help with responsiveness during session restores and memory use for large profiles (bug 711193)
  • Frank Yan’s about:home revision that I mentioned a couple of weeks ago is very close to landing, just need to sort out coordination issues with the server-side snippets service (bug 711157)
  • Silent update: Brian landed the remaining patches for the UAC dialog work.

Firefox Developer Tools

Add-on SDK

Performance

  • Snappy weekly summary

  • Livemarks are now async thanks to Marco (bug 613588)
  • There was an increase in negative feedback regarding Firefox 11 beta relative to Firefox 10 beta on SUMO. Cheng and Taras are investigating.
  • Olli and Jan cooked up about:ccdump addon for assist with finding leaks. See Jan’s blog post for more details.
  • Bill landed incremental GC this week, bug 719492. Most users will not benefit from incremental GC until Bill finishes up handling frequent “corner cases” that end up disabling incremental GC.
  • Avi ported his smoothscroll logic to C++, Jared pushed it to the UX branch (bug 206438. If you are interested in fluid scrolling, give it a try, play with acceleration prefs to help us find optimal values.

GFX

  • Fennec “maple” builds are getting usable, and we could probably use more technical eyes on them.

    • http://ftp.mozilla.org/pub/mozilla.org/mobile/nightly/latest-maple-android/

    • This is “off-main-thread-compositing”, or OMTC.
    • Probably not ready for every-day use, but already much more usable on anything with an Adreno GPU (Nexus One, HTC Desire HD, etc).
    • Known issues: Some jankiness, some WebGL issues (i.e. upside-down on some devices), some checkerboarding issues.
    • File whatever bugs you find in Core :: Graphics, and put “MAPLE” in the whiteboard.
    • Note: This testing is only needed on Android devices; desktop should be unaffected by these changes.

JS

Layout

Notable Patches:

  • bug 726582 – Prevent nsSMILCSSProperty::ValueFromString from reading uninitialized out-param

  • bug 614732 – For SVG leaf frames, use mRect to store the frame’s user space bounds, and stop using it to store its covered region
  • bug 725903 – PathExtentsToMaxStrokeExtents needs to take a transform argument.
  • bug 725897 – Remove the inaccurate nsSVGUtils::ToAppPixelRect, and use nsLayoutUtils::RoundGfxRectToAppRect instead.
  • bug 707959 – followup, move font cache telemetry into gfxFontCache::Lookup.
  • bug 725376 – Don’t do column balancing deeper than 5 nested levels to avoid hang.
  • bug 718516 – Replace call of FinishReflowWithAbsoluteFrames() with FinishAndStoreOverflow() for nsColumnSetFrame to prevent crash.
  • bug 718516 – Remove call to FinishReflowWithAbsoluteFrames until nsColumnSetFrame is fully implemented as an absolute container.
  • bug 724776 – Change SetForcedCharset to BrowserSetForcedCharacterSet.

Video

DOM

WebAPI

  • Updated WebAPI wiki page to contain status for all APIs we’re currently working on.

  • New API drafts for Device Storage, Wifi Information, Mobile Network information, Idle, Sensor and Settings APIs.
  • Philikon has initial implementation of Mobile Network Information API.

Network

Identity

Plugins

Mobile

Accessibility

Tree Management

  • Dongles installed on all OSX 10.7 test slaves – test results and wait times should be better now

Stability Report

Socorro

  • Correlation reports for Aurora and Trunk are available in subdirectories of https://crash-analysis.mozilla.com/crash_analysis/ starting with today as bug 723182 is fixed now (for some reason Socorro isn’t picking them up correctly, but this whole mechanism is a bit wonky and will be replaced with a better model in the next months anyhow). Will work on getting the version for the next Firefox cycle there near to the source uplifts.

  • Next incremental Socorro release landing on Wednesday – no big changes, a couple of skiplist additions, fix for bug 724670 which unbreaks report lists for some Java signatures.
  • Stackwalking fix for MSVC2010 (and possibly browser-side hang signatures on FF11+) could also land with this release on Wednesday, see bug 726570.
  • Main focus of work for next release is ESR support.
