  • Beta 2
    • Code freeze: Oct 19 (Yesterday)

Major Topics for This Week


  • Primarily working on Beta 2 blockers
    • Triaging the blocker list to move out non-critical bugs
  • New Core (nee Android) theme is underway
    • Working to get an acceptable level of theme in place
    • Polish and tweaking will move to beta 3

UX design

  • tracking theme work here (cleaned up today – should be easier to follow)
  • some small theme patches going in today (?) which should take a few things off that list
  • JPAKE/weave design work ongoing with beltzner, etc.
  • opening some bugs (or adding testcases) to make themeing-useful CSS techniques faster




  • new dlopen plus making sqlite not be stupid got our install size way down
    • everyone thank mwu
  • patch to make breakpad work with new dlopen waiting for review from mwu
    • expect to land today
  • file picker for chrome landed yesterday, content support landed today
    • needs testing
  • need to figure out l10n for java files
  • added lots or polish to updater and notifications, pretty good experience now
  • Android build bustage post mortem, by DougT
    • Asked to push Tim’s patch
    • Applied it, and corrected small conflict
    • Pushed to try.
    • Android didn’t compile.
    • Got a new patch from Tim.
    • Pushed to try
    • For some reason, try didn’t build Android this time.
    • Locally imported patch to my android builder
    • Built cleanly.
    • Pushed to M-C, and left
    • Failure Points:
      • My mozconfig was for the emulator (disabled thumb2)
      • Shouldn’t have just left.
        • High confidence on things would “just work”
      • Try restricted builds for no good reason.
    • I shaved.
    • (blassey) I did too. Not sure why you didn’t get a thumb2 build on try


  • MacOS X – Content not rendering without user creating UI events
    • Beta 2 Blocker
    • Looks like mac isnt processing ipc messages it needs to
  • Priority of child process (Alon can update everyone)
  • Discussion in bug on dynamic verses constant child priority
    • Constant priority makes the child slower (at least 3% on page load for one test).
    • Dynamic priority is hard.
    • I am bias.

General Platform





  • Content Sink pref change loaded (Bug 604762)
    • Basically we make the child process less “responsive” and make it do more work before processing events
    • Saw page load perf bump by 3%






Release Engineering

  • 3 tegras running 3 talos suites on m-c and tracemonkey only
    • adding more suites over time
    • scrounging up more tegras
    • bugfixing as well — please let us know if something’s not working right
    • currently tracking why the Talos results drop off of TBPL after test run is complete – bug 605856
  • android multilocale — untested poc manual build w/out packaged manifests
  • 4.0b2 will be lsblakk
    • aki pto Nov 20-Dec4; trying to hand over process before then
    • bugfixing & documenting



  • DougT spent 2-3 days fixing talos.
    • The Fennec CLH was registered using a prefix that loaded before talos CLHs.
    • Alot of voodoo trying to get the right options, right config file, right files on disk.
    • TPan doesn’t work on desktop
    • Tp4 doesn’t produce the correct starting output on desktop
    • Not all bad news, Ts does work on desktop
    • I am pretty sure that these failures would also fail on the n900 given their subsystems (linux, apache) are basically the same.
    • What I want is a way to locally test performance using the tools we currently have.
    • (aki has considered rewriting talos in mozharness, which would hopefully make it easier to config, but this is not a small project and would require buy-in, also probably not as high priority as 4.0b2 releng blockers)
