Firefox Development

• bug 727120: ttaubert switched the Thumbnail service from using the cache to just using files on disk
• bug 641892: contributor OHZEKI Tetsuharu added support for displaying multiple types of notifications at once. Great work!

Performance

• Perf work week May 14-18 (next week) in MV.

• This week's Snappy summary
• Bas is working on slow downs due to borders and gradients. We should see some improvement in 3-4 weeks.
• Incremental GC should turned back on soon (bug 750424, bug 750416).
• Kyle’s big memory leak fix from last week turned out to occasionally cause leaks where there were none before (bug 751466).
• Tim moved thumbnail storage away from network cache, which reduces cache contention and browser freezes (bug 744388).
• Paulo continued nuking sync favicon api usage (bug 728168).

JS

• Compartment Per Global landed and stuck. Expect ongoing bug stomping to continue as the rest of the source base adjust to these patches (bug 650353).

• The new jsdbg2 Debugger object are now available from scratchpad. A screens cast from the Toronto meet-up provides more detail (https://www.youtube.com/watch?v=WKIkOcuVG7w) (Bugzilla jsdbg2).

Layout

• SVG and CSS working group meetings this week (including joint meeting Wednesday)
• likely some large changes to font size inflation coming soon to increase the size of the areas in which we make separate inflation decisions (bug 707195 and duplicates/dependencies)

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.

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), Samsung, 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.

DOM

• Compartment per global landed! (bholley, luke)

Tree Management

• stage/ftp/surf moved to scl3 datacentre on Saturday. Some fallout on Sunday/Monday. If you see any more issues (e.g. downloading builds/tests), please ping IT/RelEng.

Stability Report

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 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
