Video

Support for the new Opus audio codec has landed in Nightly, pref’d off. Set ‘media.opus.enabled’ to true to try it out. This was bug 674225.

There are some test files at https://people.xiph.org/~giles/2012/opus/

Opus is a new audio compression technology we’ve developed together with Microsoft (Skype), Broadcom, Google, Xiph.Org and other groups. It’s in the final stages of standardization at the IETF. It will be an essential component of our WebRTC (a/v chat) effort, but we also hope to get some traction with it as a baseline audio format for HTML.

We’re getting ready to land the first chunk of WebRTC on the tree to support getUserMedia() work (Camera API, etc). This will be preffed-off initially, and we’ll be calling on people to help when asked to do reviews, etc. This is a bit like docking a cruise liner in a narrow slip… so your help is appreciated.

DOM

• Compartment per global landed! (bholley, luke)

WebAPI

Network

Identity

Plugins

Mobile

Accessibility

• Fennec talks! See MarcoZ’s blog for details.

Bugs marked sec-review-needed that need to be scheduled

Stability Report

Work Week

• Stability work week will be June 11-15, 2012 in Mt. View

Socorro

• Planning for Rapid Betas is ongoing, will push out previously planned work for some time.
• B2G and WebAppRT should probably get crash reporting as well, please coordinate with KaiRo to get this moving!

Desktop

Trunk

• Some new regressions cropped up:
  • bug 751826 crash in mozilla::plugins::parent::_getproperty
  • bug 752414 crash in nsXPConnect::CheckForDebugMode @ JS_GetCompartmentPrincipals (still crashing after backout)
  • bug 752824 crash in nsXPConnect::CheckForDebugMode @ JS_GetInternedStringChars
  • bug 752416 crash in nsXPConnect::CheckForDebugMode @ js::AllFramesIter::AllFramesIter
  • bug 752391 crash in js::gc::MarkRange
  • bug 752495 crash in js::IncrementalReferenceBarrier
  • bug 752309 is current topcrash and a regression from compartment-per-global, bholley is on it.

Beta

• FF 13 Beta 2 data looks good so far relative to new crashes.
• Many of the top crashes are hangs
• Explosive report shows more flash issues: https://crash-analysis.mozilla.com/rkaiser/2012-05-07/2012-05-07.firefox.13.explosiveness.html

Aurora

• [[2] Aurora Top Crashes]]
• bug 700288 is the top crash

Firefox 12

• bug 640904 appears to still be the top signature on 12

Mobile

• Aurora top crashes are mostly libdvm crashes, bug 730890 was fixed in nightly, waiting aurora approval; remaining Libdvm bugs are as seen:
  • bug 751967 – crash on new tab/google maps galaxy nexus, ICS, 5.03 build
  • bug 751262 – Dalvik VM aborts and Fennec dies sometimes after Fennec and Android device are idle
  • bug 750965 – crash in libdvm with continuous reloading page after a while
• Nightly top crashes; bug 748531 catches exceptions in JNI code. This was also fixed recently and may need to be aurora approved?
  • bug 752428 – crash in nsDOMWindowUtils::SetDisplayPortForElement
  • bug 752426– crash in mozilla::AndroidBridge::TakeScreenshot
  • bug 737128 – mozilla::gl::GLContextEGL::ReleaseSurface GL crash on Droid X

• note: Nightly could be inflated due to QA testers testing and trying to get repro steps; also takes a while for a fix to have a crash fall off the chart.
• Reminder: please update your builds to help show impacts of crash fixes

Performance

• This week’s Snappy summary
• Kyle landed a very significant Snappy fix this week as part of memshrink that reduces leaks in chrome (bug 695480). It should significantly reduce memory usage and thus cycle-collector pauses, etc.
• Patrick landed a change to have Firefox now hedge bets and warm up a TCP connection while checking the cache (bug 729133). More details on Patricks’s blog.
• Work going into improving setTimeout (bug 743877, bug 715376).

GFX

JS

• FIXED: bug 750424 nsXULPrototypeNode::Release should add itself to the purple buffer. This was blocking bug 735099 Re-enable incremental GC

Layout

Fennec and other bugs:

• bug 728284 – Main container layer has siblings that are drawn in the background
• bug 732016 – Maple: scrollIntoView does not clamp to the page size

• Hoping to land GPU-accelerated clipping to border-radius today bug 716439. Fixes various performance problems with scrolling inside elements with border-radius, and canvas/video with border-radius. Some big changes. (ncameron)

Video

• Landed MediaStreams infrastructure on mozilla-central (roc). Currently the only exposed APIs are mozCaptureStream/mozCaptureStreamUntilEnded on media elements and the ability to set MediaStreams as the src of media elements, so you can route video/audio from one media element to another. Not that useful by itself, but a foundation to build other APIs on (getUserMedia, WebRTC, audio/video processing) etc. Next step is to land some processing functionality.

• Not video, but Nick is going to land a patch to disable attempts to remove our exception handler that triggers breakpad. This may reveal latent crashes.

DOM

WebAPI

Network

Identity

Plugins

Mobile

Accessibility

  • needs 5+ hours
