  • crbug.com/736807 turned out to be due to the toolchain binutils uprev from last week (e.g. breaking auron_paine). This was reverted and many builds became green.
  • Filed various bugs for broken builders. Seems like we should look into update_manager (e.g. crbug.com/578270)
6/19 ~6/23
Sheriffs: kirtika, pmalani

State of the test lab (6/19)
  • Chrome pinned due to a bad CL (not yet identified) that brought down kitty & blaze last week. Partly happened because we don't have any coverage for nyan on the PFQ. (crbug.com/734074)
  • hwtest lab will be shutdown tonight and tomorrow night. 
  • kirtika@ to do a kernel merge (6/20 afternoon) - Intel wifi driver drop.  
  • Infra team: 4+ bugs to be filed for servo and repair (1 specific to servo on kitty, 3 others about how the servo repair process failed in the case of the kitty errors). 

    6/5 ~6/11
    Sheriffs: bleung, mcchou, mojahsu
    • 729766: autoupdate_EndToEndTest.paygen_au_canary_full, on a bunch of boards. Suspect AU from R53 8530.96.0
    • 730272: hostinfo attributes refer to incorrect job_repo_url, causing tests to fail
    • 731253: Skylake and Elm CQ failed due to drm patch from Intel. Error message is misleading, suggesting a failure in the infrastructure rather than a HWTest system that legitimately did not boot with the new image. crbug.com/731274 was filed to improve the messaging.

          • master-paladin infra failures (build 12292): this CL broke several paladin builds. Told the CL owner not to mark ready before fixing problems.
          • master-paladin infra failures (build 12294): failed 4 consecutive times. 20 paladins did not start in CommitQueueCompletion. Similar to build 12281 yesterday but build 12283 passed later.

            • master-paladin infra failures (builds 12301, 12302): failed in these 2 builds
            • Looked similar to crbug/593423: Need to watch this as more builders were broken due to the timeout issue.
            • Build 12303 passed. Flaky?

            7/29 Notes for the next sheriffs from aaboagye, kirtika: 
            • Major issues we are seeing, format is <Impact: Issue: Links>::
              • Tree closure, fixed now: "No space left on device" for cheets builds: aaboagye@'s post-mortem here. crbug.com/630426. 
              • CQ failures: We've been seeing intermittent failures due to hitting git fetch limits with gerrit (commit queue sync step doesn't work). The current CQ run failed due to this, would not be surprised if the next one does too. crbug.com/632065.
              • Several canaries failing: Unit-test times out, possibly due to overloaded machines: crbug.com/627881
              • Android-PFQ failures: adb is not ready in 60 seconds: crbug.com/632891. 
            • Minor issues, work-in-progress: 
              • Android-PFQ: mmap_min_addr not right on samus/x86: crbug.com/632526.
              • Paygen/signing issues.
              • Autoupdate-rollback (likely network SSH issue): example crbug.com/596262.

              • x86-zgb: Pool-health issue, infra (kevcheng@) looking into it, may be back up next canary run? 
              • x86-mario: Not sure if the manifestversionedsync is a real issue or not, filed crbug.com/631867 anyway. 
              • Paygen failures: falco, falco_li, gru, jecht, kip, lumpy, ninja, parrot, peppy, samus, smaug, x86_alex-he, stumpy. TBD: Update more details here.

                  • Fixes posted to gerrit and making it's way through the CQ.
                • Still some unittest failures. There's a CL that just landed to reduce the parallelism. Will be following to see if the situation improves. crbug.com/627881.
                  • That CL did not seem to resolve the issues.
                • Saw a few canaries yesterday (celes this morning) that had issues when uploading debug symbols. dgarret@ is working on a fix. crbug.com/212437.
                • security_StatefulPermissions is pretty flaky, veyron_minnie canary failing on it. wmatrix is all red: https://wmatrix.googleplex.com/retry_teststats/?days_back=30&tests=security_StatefulPermissions. Investigating crbug.com/604606

                • Towards the end of the day, a larger number of canaries were failing at the paygen step. I think what may be happening is network flakiness, but I wonder why we don't just retry again?

            • Canaries
              • Several of the canaries were failing in the platform_FilePerms HwTest.
                • This was seen on cyan, elm, lulu, oak, samus, and veyron_minnie.
                • Appears to be missing expectations for ARC containers.

            • CQ
