Major Topics for This Week

• Beta 4
  • One blocker remains: bug 624652 : Nexus S can hang after opening a few tabs, requiring battery removal

Front-end

• Working on 2.0 blockers
• Working on performance issues
• Beta 5 blocker list will start forming
• Went through blocker list with Madhava and Thomas looking at UX/UI issues
• Reflow-on-zoom is at risk. We need a plan and we need criteria for shipping 'on'

UX design

• working through these 2.0 blockers:
  • bug 611580 - Character Encoding Menu for Fennec
  • bug 618434 - When device has no wireless connection (wifi or cell) jpake screen has no code
  • bug 622578 - form helper navigation bar should not obscure web content when only the NEXT / PREV buttons are shown
• zoom reflow bugs: bug 623820, bug 623831, bug 627103
• writing b4 what's new post
  • list of what's new here: http://etherpad.mozilla.com:9000/A52pwBYA3c
• working on UX "roadmap" for post 4.0

Android

• from last week
  • bug 623999 fixes 35s worst case startup, resolved
  • bug 623136 reduces font loading from 600+ms (worst case) and 100ms (average case) to 2ms, needs review, pushed to b5
  • bug 621015 fixed by android update which has propagated to most phones by now

Release Engineering

• tegras
  • tl;dr: still 0 in production
  • bear pulled an all-nighter to get staging reliably green. we then spent the rest of the day checking this in, rolling it out, and finally switching some tegras to run in production.
  • at this point we noticed/remembered that bear's testing staging environment was running against thursday's nightly, with old devicemanager code.
  • assuming we don't regress anything further, we've solved 1 of 2 blockers to going live. we'll be working on incorporating the devicemanager changes and testing against the new shared id today.

QA

• New Bugs over the week: filed
• Results from nightly Smoketest runs

Top 5 crashes:

1)libz.so@0x14b4 - 299 crashes

Related bug: Bug 626051 It is #1 top crasher in Fennec 4.0b4pre for the last week. There was a big spike for this crash in the last 3 days(81 crashes to be exact). Steve Kondik commented that this is mostly on CM7(Gingerbread version). CM isnt released yet and hence they re still testing their nightly. Hopefully this should be fixed in final release.
