Quality Programs

(An opportunity to hear about status with the various quality programs that do not have a formal team structure.)

MemShrink (njn)

  • Timothy Nikkel fixed bug 847223, which means we no longer decode all images in a page when its first loaded. This can make an enormous difference on image-heavy pages — we have one example where peak RSS dropped from 2,400 MB to 280 MB. On that same page the loading lag dropped from 5 seconds to 1 second. Assuming no problems are found, the constitutes the completion of the #1 item (“Better Foreground Tab Image Handling”) on the MemShrink big ticket items list! Generational GC will be the new #1.
  • I am in the process of cleaning up the memory reporter infrastructure. One major change that just landed is that nsIMemoryReporter was removed, and nsIMemoryMultiReporter was renamed as nsIMemoryReporter. It’s possible that this might break functionality in some add-ons.

OrangeFactor (ryanvm)

  • Past week’s OrangeFactor: 4.69 (Previous Week: 3.41).
  • Shout out to Victor Porof of the devtools team for landing some major cleanups to the debugger test suite in bug 876277.
  • *30* intermittent failures fixed in the last week – List – Thanks!.

Stability (kairo/bsmedberg)

  • Overall numbers look good for releases and uplifts.
  • Nightly is a mess, but the bugs are all filed and appear to have owners.


(Comments and questions that arise during the course of the meeting or otherwise do not have a section.)

  • Is Haida targeted at desktop platforms (or Android)? The page seems be to all oriented to B2G. Whe will be the change; how well will this match with OS UIs and across all platforms?
    • B2G only
  • What changes should we expect for about:home (lmandel)
    • Focus on top sites more than bookmarks

<Read only beyond this point>
