Key Issues

Actions Last Week

• Milan to assign https://bugzilla.mozilla.org/show_bug.cgi?id=805745
• Jet look into https://bugzilla.mozilla.org/show_bug.cgi?id=696640
• Naveed look into https://bugzilla.mozilla.org/show_bug.cgi?id=817342

Issues

  • MOZ_MAKE_FLAGS removal
  • C++11 atomics
    • https://groups.google.com/forum/?fromgroups=#!topic/mozilla.dev.platform/BsMJpfWf2ak
  • ICU Import

Roundtable

• Meeting Survey Results & Actions
  • Survey Results
    • Overall rating 6/10
    • 93% learned something unexpected
    • General agreement orienting around products is more useful
    • General agreement monthly updates on certain topics are useful
    • General agreement calling attention to key issues helps
    • Sentiment that Metro, Snappy should have less frequent updates
    • Sentiment that Memshrink should have more frequent updates
    • Sentiment that Dev Tools should have its own section
  • Proposed/Possible Changes
    • Put the surprising info and actions first (starting today)
    • Add DevTools back (discuss)
    • Make Snappy, Metro, Memshrink changes (discuss)
      • njn publishes a detailed report of MemShrink activity every two weeks. We can link it here if people would find that to be useful, but in the interests of not wasting peoples' time, perhaps occasionally encouraging people to subscribe to njn's blog would be more efficient. https://blog.mozilla.org/nnethercote/
        
        If linking njn's status reports here isn't sufficient, we (MemShrink folks) would appreciate discussing alternatives in an asynchronous fashion (e.g. a newsgroup) instead of at the platform meeting. Most of the MemShrink folks don't regularly attend the platform meetings, either by choice or due to geographic constraints.
    • Written only status updates for platforms, other pieces (discuss)
