Agenda

  • Will Lachance has made some awesome build charts which show what's happening when for each commit. Need to discuss findings. Possible action items:
    • Split mochitest-browser-chrome out from mochitest-other, to bring all test chunks into the 30-min target range. Currently mochitest-other takes 60-90 minutes on debug builds.
    • Investigate what to do about long builds that are caused by full hg clones and full builds on clobbered machines.
  • Review the Action Items & Bugs

Action items from last time

  • [DONE] will to follow up with catlee regarding dashboard calculations - new calculations are used in the GoFaster dashboard
  • [DONE] jgriffin to change test run comparison routine to compare against a range of recent m-c runs instead of one run to help mitigate the fact that test durations vary considerably per run, even when equivalent
  • [DONE] jgriffin to get data on infrequently failing tests, and how long they take to run
  • [DONE] ted to file bug about harnesses downloading symbols on demand - bug 679759
  • Any p2 bugs need to escalate?

Review [buildfaster:p1] bugs

Review current activities

  • we've put investigation of running debug tests with opt xpcshell on hold, since opt debug builds seem likely to materialize sometime soon (bug 669953)
  • still need a mechanism to track individual slow tests; jmaher suggested the correct metric to do this is test duration/test asserts; need to update the logparser to handle this

Review [buildfaster:?] bugs

Questions

Actions for next time

  • catlee to add builder name to the .csv that's being used to generate the buildcharts so we can filter out re-triggers and nightlies, etc
  • wlach to update buildcharts to indicate job submission time, so it's easier to see wait times
  • catlee and jgriffin to coordinate re: gofaster session at the all-hands
