Performance

• This week's Snappy summary

• Ludovic Hirlimann blogged about spotlight taking a lot of time indexing the Firefox network ‘Cache’ directory (bug 718910). If you experience this problem please try the solution in the bug and comment back with results.
• Tim Taubert blogged about reducing new-tab jank.
• Nick Hurley landed a change to reduce our maximum cache size to 350 megabytes (bug 709297).
• The Necko team is working hard on addressing significant problems in the networking code. These problems are tricky and will take a while to fix but should have big payoffs.

Media

• Just landed support for hardware decoding (a.k.a. platform decoders) on Android ICS/JB: Bug 782508.

  GB support should be following in another week or so. Playback performance on ICS/JB currently is ok, but not stellar. Once we add GB support, we will work to improve the performance. This patch should work across all Android hardware phones running ICS/JB -- however, some hardware implementations are known to have bugs, which we will need to work around. If you try this code on your ICS/JB device and it doesn't work, please file a bug.

• Currently targeting to release WebRTC in Firefox 18 (not behind a pref).

Accessibility

• Android SDK has been bumped to 16 on Mozilla Central - via bug 783706. This is required for Jellybean a11y support which has landed on inbound.

Stability Report

• stability@mozilla.org mailing list for crash issues.

Socorro

• Rapid beta work should release around the week of Sept 10th

Desktop

• New Flash release - 11.4 out today
  • Hoping it addresses further issues.
  • Marcia/Juan verifying symbols uploaded and we are receiving crash data.
    • Confirmed OOOP crash on Win 7 with .265 Firefox beta
    • Mac crash report with .265 so far is giving no report found

• Hangs
  • Tracking issues with hangs for some time.
  • bsmedberg wrote up Socorro/Hang Processing Proposal for a better way to process hangs.
  • Socorro team says we can have this mid-Q4. bsmedberg is thinking about custom handling of hang reports from nightly/aurora/(beta?) until then to produce useful data, bypassing socorro.

• Trunk
  • High crash rate
  • Top crash on the trunk resolved fixed then reopened - bug 781265.
  • bug 782981 now fixed but polluting the stats.
  • New bugs
    • bug 784365 runtime abort in nsIFrame::BuildDisplayListForChild

Mobile

• Top crash on mobile bug 776334 fixed and uplifted to beta.
