Quality Programs

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

CritSmash (dbolter)

MemShrink (njn)

We can now do fast, coarse-grained, per-tab memory measurements. This will become a devtools widget eventually.

OrangeFactor (ryanvm)

  • Past week's OrangeFactor: 4.56 (Previous Week: 5.12).
  • 13 intermittent failures fixed in the last week - List - Thanks!.

Stability (kairo/bsmedberg)

  • Gathered some data on stability work within the last year, here are some highlights:
    • Desktop browser crash rate is the same as a year ago (~1.0 crashes per 100 ADI), despite aggressively adding web features in that time
    • Plugin hangs and crashes are less than half of what they were a year ago (when Flash had an all-time-high on issues), thanks to work on both our and Adobe's side (0.8 -> 0.3).
    • Android crash rate reduced by 67% (2.4 -> 1.6).
    • Nearly 1500 crash bugs fixed within the last year.

<Read Only>

  • Stability numbers for yesterday are still waiting on ADI numbers to arrive.
  • ASUS gamer OSD is now blocklisted on Fx27, which kills our #3 topcrash (pending approval Fx26) bug 812683
  • A new version bitguard.dll is causing signification crash issues across channels. Currently we are unable to blocklist this DLL because it is loaded via APPINIT before the Firefox DLL blocklist is installed. dmajor has a theory of how we can fix this by not linking firefox.exe against user32.dll

Roundtable

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

  • (RyanVM) B2G26 (v1.2) now has its own Gecko branch independent of mainline Firefox.
    • https://hg.mozilla.org/releases/mozilla-b2g26_v1_2/
    • Only koi+ blockers should be landing directly on this branch unless cleared by Release Management.
    • Regular mozilla-beta -> mozilla-b2g26_v1_2 merges will be performed to keep the underlying Gecko revisions in sync.

<Read only beyond this point>

Friends of the Tree

There were great changes by volunteers in Core and Toolkit during the past week. Thanks to all of these contributors for their passion and hard work! Here are some highlights:
