Status reports

Dev team

  • Make it easy to use Robocop to add some UI talos performance tests for various UI pieces:
    • Time to open the Awesome Screen
    • Time to load basic Awesome Screen results
    • Time to open Tabs List with X tabs open
    • Time to display core UI
    • Time to display about:home

Rel Eng

  • bug 723667 - talos robocop
    • sut agent upgrade patches being reviewed and soon to be landed
      • armenzg verifying with jmaher that sut agent upgrade does not cause regressions to other suites
    • talos robocop jobs are still going red
      • jmaher got it working manually when its first run went red
      • armenzg has triggered another 3 jobs of each to see if anything changes

A Team


  • not copying fresh profile over each test saves us about 1.5 minutes per test, or almost 20 minutes for a full run
    • patch in progress, eta friday
  • when launching via sutagent, we seem to take 30 seconds longer to run a test vs launching with adb. A future area for investigation to save time


  • in looking at the reftests that require larger resolution (I believe there are 10 of them), we do not run them on android and should consider not adjusting our resolution. This will save us 10 minutes per reftest job or 180 minutes of machine time per checkin.
    • side benefit is we will have more memory for fennec and might reduce our hangs or random failures (not proven or tested much)
  • bug 732498 - need somebody from development to help drive/fix the reftest failures between xul/native/e10s and android in general


  • bug 732206 - maple ts and txul are busted, ts appears to be green the last few runs
  • new is being used, now we can iterate faster on talos changes
  • need to do ts-mozafterpaint

Upcoming work:

  • xpcshell (need new sutagent rolled out- in progress)
  • powermeter

S1/S2 Automation

  • public facing graphs will be available by end of the week


  • automated tests are running

Crash Stats

Panda Boards

  • from ctalbert: "panda still needs a new build, going to rebuild it today"

Carry over info


  • IT is concerned about not having remote re-imaging
    • jake has ideas to try once he has time to use pxe
    • this is not a high priority right now
  • the boards sometimes become unstable (much more than the tegras)
    • we have to remember that we are using tip of ICS and will take time to settle
  • armenzg: do we have an alternative to the panda boards?
    • blassey: no fallback plan
  • bug 725544 - Android 4.0 tracking bug
  • Pandaboard Setup docs
