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.

GBrown

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

• Input issues in designMode document (Etherpad): bug 719121, bug 721393
