RELEASE PLAN (WIP): http://mzl.la/TDjx55 (will be updated this week to reflect branching)

    • This week:
      • No audible, nothing new.
    • Last week:
  • Developer Documentation (sheppy)
    • This week:
      • Debug guide work starting this week; questions are beginning to be asked! You have been warned!
      • I have been approved formally for an Otoro! Don't have one yet, but hopefully soon.
    • As always:
      • Don't forget to add the dev-doc-needed keyword to any bugs that even might affect developer docs (whether device integration developers, Gecko developers, or web developers). You don't have to wait until the bug is fixed. We have tools to track this, and using it will get things done faster.
      • On Github, use devDocNeeded label (current open issues: http://j.mp/NTBybM ), for example, make sure everything API-related you talk about in these meetings have the keyword.
  • <Release Engineering> (Joduinn)
    • This week:
      • contractual details of how-to-do-updates
    • gonk vs gecko vs gaia updates (and who changes source)

      • focusing on setting up two sets of builds, with updates
      • "tip" (not calling nightly/daily - implication of 24hour cadence)
      • "stable" (not calling weekly - implication of 7 day cadence)
      • meetings w/RelMgmt, B2G, ateam, l10n and IT
      • to give context, agal wants tip of tree development on github, and releases ship on hg.m.o

    • Last week:

  • Predictive Text (Christoph)
  • Camera (Mike Habicher)
    • This Week:
      • bug 779139: cycle-collection participant
        • review has started, but patch has bit-rotted (turns out git wasn't pulling in all the latest changes--bad git)
        • patch has been updated, and in the process, working on:
      • bug 781892: preview freeze
        • behaviour is different with hardware-accelerated camera preview
        • preview usually fails after 1 photo
        • thahave observed there is a GONK_IO_SURFACE leak post-photo taking: it looks like the camera hardware is trying to send us a post-view buffer, but we never receive/accept/free it
        • after taking one photo, we receive-but-immediately discard a few more preview frames, and then the preview callback just stops. (If only we had access to the libcamera source code....)
        • also, preview stream never stops/gets released, which is also causing leaks
      • bug 782456:
        • it turns out /dev/msm_camera/control0 is not rw in OOP, which it needs to be
      • bug 779138: onShutter/onClosed event patch was complete and working
        • has likely bit-rotted along with the 779139 patch above, however.
      • bug 779145: worked on in tandem with 779138
        • also likely bit-rotted
    • Last Week:
      • bug 779139: patch posted for review
        •  :khuey as agreed to review the DOM-facing objects, review pending
        • still need a reviewer for the Gonk-facing objects--any volunteers?
      • bug 779138: tested the changes (actually for OnShutter support right now, but the idea is the same)
        • setting the event handler causes an camera-control object leak
        • can anyone help out with what's involved in doing this properly?
      • bug 781892: camera viewfinder freezes after taking 4 to 6 photos on Otoro
        • UI is still responsive, camera code thinks it's pushing preview data (and it is), pictures can still be taken
        • working with :roc on diagnosing what's going on in the MediaStream layers
    • In The Queue:
      • bug 776934: need to add camera access permissions check
      • discussions on how to integrate camera control with getUserMedia(), and what can be accomplished in the time available
      • bug 776062: video recording
        • need to rebase this patch on other changes, as soon as they land
  • ---> geo: what does QA need from me for the camera?
    • Please contact dclarke@mozilla.com -- we're querying devs re: API completeness, existing tests, thoughts on test approach, and closing feedback loop after test plans are written.
  • Browser API (jlebar, dale)
    • This week:
      • Bugs fixed:
   Fixed race condition in browser initialization, which was causing orange that prevented a lot of other things from landing (bug 772076)
   X-Frame-Options re-enabled (bug 770239)
