Schedule

  • Merge happened yesterday
    • mozilla-central is now 13.0a1
    • native builds are in mozilla-beta
  • Beta is in day-by-day slip until we get our blockers handled

Major Topics for This Week

  • Crashes:
    • Still high on 12.0a1 (~30 per 100ADU), but we should get down to ~10 per 100ADU when the Skia top crasher hits the wild
    • 11.0a2 is lower (~10 per 100ADU), but still needs some work
  • UI Responsiveness:
    • Tabs tray has improved quite a bit. Still some wins we could make.
    • Awesomebar improvement patches exist, and we have other approaches to investigate too.
    • Startup UX has improved quite a bit on 12.0a1
  • Checkerboarding
    • Several options exist, none may help in time for final release. Doug and his team are working on the options.
    • 11.0a2 has less checkerboarding than 12.0a1 due to some in-progress work. That work will be backed out of 12.0a1 and moved to a branch.
  • Strings:
    • We are turning away non-blocker patches that have string implications.

Last week:

  • Robotium tweaks continue, but it's quite stable and ready to use: See https://wiki.mozilla.org/Mobile/Fennec/Android#Robotium
  • Investigated bug 716948 - LinkedIn buttons are blank when viewing invitation -- it was a dup
  • Mostly worked on bug 696095 - Create Fennec startupCache at build time
    • I can build the startupCache at build package time via the Android emulator and update the APK; need some releng work, etc to land...but I'm not seeing performance improvements to justify the increase in build time, etc. -- still investigating.

Next week:

  • Try to wrap up bug 696095.
  • Bug 705192 - remotexpcshelltests.py cannot execute xpcshell via SUT agent

    • Agreed with Brad and Doug on a workaround (Doug implemented the actual fix - just to catch the exception)
  • Input issues in designMode document (Etherpad): bug 719121, bug 721393
