  • [MISSED] Get rid of the long tail of C++ objects that are still exposed to the web using XPConnect
    • We had less time for this than expected due to a previous quarter missed goal taking longer than expected to finish up (now done). Everything left on this list is already moving or planned, but will flow out into Q3.
  • [DONE] Get LeakSanitizer builds enabled by default (bug 988041)

  • [MISSED] Land all non-cache bits of Service Workers preffed-off (on is a bonus) on m-c (nsm)
    • While this goal as written is a miss the overall progress towards Service Workers is progressing very well. This missed due to us not getting other resources on this quick enough due to other responsibilities, but velocity is really good now.

WebAPI

  • [MISSED] finalize moving main thread IDB to PBackground including blobs (bent)
    • Lots of other things pulled bent away from this but it's progressing well when he has the time to work on it.

    • Jan took care of a bunch of the work leading up to this, but that took longer than expected.
  • [DONE] clarify design and spec issues around Fetch for Service Workers to ensure they're implementable (annevk)
    • ServiceWorker work is not blocked on the Fetch spec at this point, and our implementation of Fetch is moving along.
  • [MISSED] implement gecko side of manifest spec (bug 997779) (marcosc)
    • Implement processing of V1 members (name, orientation, display, icons, start_url).
    • This did not make it due to vacations and the lack of others' review bandwidth.
  • [MISSED] finish device orientation spec with Mounir (marcosc)
    • Write tests for all conformance requirements.
    • Publish LC by Monday, June 30.
    • work has been done here and is waiting on the review of others and integration afterward
    • a re-write has begun here and it didn't happen by the end of Q2

JS

  • [MISSED] 941796 Generational GC on Firefox OS [Scale FirefoxOS]

Accessibility

  • [DROPPED] Gather data and produce a report on performance wins vs resource costs of the seer on several desktop and mobile scenarios. (hurley)
    • We've decided to re-name the seer the "network predictor" and to re-write it using the HTTP cache instead of SQLite, with Q3 target. So no performance numbers will be available this quarter.
