Products/Projects

Firefox Mobile

• bug 749063 Check out Chris Lord's Blog Post about Progressive Tile Rendering: http://chrislord.net/blog/Software/Mozilla/progressive-tile-rendering.enlighten
• h.264 Decoding: Fx17: fixing remaining blockers open bugs for ICS and JB bug 787226. Gingerbread support for Fx18 is at risk in favor of ICS and JB quality (need to land GB by Nov 5th for 2 weeks of bake time on trunk prior to uplift).
• Readability 2.0: Reiterate prototype status for Reflow-on-zoom. Goal for stabilization is Nov. 5th so we can get as much real world testing as possible

Stability Report [Weekly]

Desktop

• TRUNK Fx19 - top unresolved crashes
  • bug 801453 - mozilla::image::RasterImage::Discard - fixed by another bug - check in 10/23 build then the crash rate should go down significantly

  • bug 803262 - mozilla::FrameLayerBuilder::CheckDOMModified

• AURORA - Fx18
  • Tracking 18

Not as much concern for other channels at this moment:

• 16.0.1 Release top crashes

B2G

• https://crash-stats.mozilla.com/products/B2G
• Symbols still needed for crash reports to get meaningful stacks on Socorro
• UI for reporting on b2g still outstanding
  • Design has been finalized
  • Margaret helping out with implementation
• Still working on ADU data so may not be able to use crashes per 100 ADU metric
• Dogfooders - please log crashes, in particular anything that's reproducible - add the crash keyword.

Snappy [Weekly]

• Snappy update #41
• Oct 18 Snappy minutes

• Matt Woodrow reduced tab-close animation jank (bug 750417)
• To answer JP's question from last week about the impact of Jeff's change on tab switch times, we've landed a Telemetry probe on Aurora and will shortly be able to take a real look at the before and after for this change

Mobile Web Compat [2nd Tuesday of Month]

• Lawrence gave an update during yesterday's project meeting. Video, Slides
• Test event today, 12pm PT in 10 forward and on Air Mozilla.

MemShrink [4th Tuesday of Month]

• Memory consumption is critical for B2G. Lots of work is being done, especially by Justin Lebar. Hopefully it will be enough at this late stage. The tracking bug is here.

• Gary Kwong got Valgrind tests green on tinderbox. Next steps are to run them on more test suites, more repos and more often -- often enough to unhide the results. This will require (moderate) releng resources that are currently strained by B2G.

• We're watching the social API closely for problems such as bug 794712 (which was a Facebook problem). Please file bugs and tag with "[MemShrink]" if you see problems.
