Status reports

Dev team

Rel Eng

  • Callek: xpcshell tests are live on cedar and are easy to turn on for other trees (try, inbound/central). Have a high setup cost (30 minutes) but our test capacity can handle this currently bug 828069
  • kmoir: Landed change to run mochitests slower which should diminish the number of panda reboots until power supply issues are addressed bug 811444

IT

  • Still working on a higher density chassis, parts coming in to build a prototype.
  • Issues with pandas rebooting may be lack of sufficient power. 3 new power supplies installed to test this theory. 3 weeks lead time from the manufacturer to get more

A Team

  • failure rates
    • tegra: [4.59%]
      • mochitest 1,2 and robocop are the biggest offenders
    • panda-all: [18.52%] - this is raw including robocop which is hidden on tbpl
    • panda: [4.35%]
      • jsreftest 1,2 and mochitest 7 are the biggest offenders
  • panda board reboot problems
    • hypothesis is that our power supplies to not provide enough power, adding a second power supply will reduce our reboot and connectivity problems
    • tested in chassis #2 before and after power supply addition, saw great improvements (12% to 2% failure rate)
    • been working on testing in new chassis.
      • Before I was seeing 12-25% failure rate on the smoketests
      • now I am seeing 4.6%, 7.5%, 9.0% running the same tests.

x86 automation

  • Possibly obtaining x86 phone for Autophone testing.

Autophone

  • setup bandwidth limiting per device via:
sudo ipfw pipe $pipe config bw 780Kbit/s delay 100 plr 0
sudo ipfw add $pipe pipe $pipe ip from $hostip to $ip out
let pipe=pipe+1
sudo ipfw pipe $pipe config bw 330Kbit/s delay 100 plr 0
sudo ipfw add $pipe pipe $pipe ip from $ip to $hostip in

Eideticker

  • Still trying to get a finer regression range for CNN page load on LG G2X (bug 855019).
  • Finally got cross browser page load test up. Found that our performance was bad, filed bug 857359 to track.
  • Discussed with jchen idea of a new checkerboarding metric using frequency content analysis of capture frames for sharpness/density. Filed bug 857644 to cover investigation.
