Possible bugs

• Write a tool to update bugzilla bugs for outstanding machine loans and ask if the loaner is still needed on say, a weekly basis: https://bugzilla.mozilla.org/show_bug.cgi?id=1171165
• Long Inter-Job Timing on t-yosemite-r7 https://bugzilla.mozilla.org/show_bug.cgi?id=1258480
• Create new script to setup a buildbot master for development: https://bugzil.la/1275135
  • [alin]: Iris & Alison are working on this

From coop:

• https://bugzil.la/1253312 - TC Linux 32 debug builds Tier-1

From kmoir:

• How are preparations for the mercurial upgrades going for build/test machines? (to support bug 1298976)
  • [alin]: still need to be done for Windows 10 testers
• Other possible bugs:
  • Schedule win10vm test jobs on try https://bugzilla.mozilla.org/show_bug.cgi?id=1304065 - what’s the status here?
    • No longer needed since we aren’t going to support w10 buildbot
  • Create alerts for t-w732 and g-w732 pending https://bugzilla.mozilla.org/show_bug.cgi?id=1304158
• Is there further automation that you can implement to make regular tasks easier i.e. the machine loan email as a template
  • [alin]: as discussed in Hawaii, we’ll start investigating what improvements can be done here
• Other goals
  • Puppet master upgrades: we're on a really old version, and should have a better story for upgrades going forward. We can move a single platform to start(kmoir needs to open bug here and ask arr on current state)
  • Talked to Rok this week re moving releng web properties to releng services. He said that his documentation is ready to use and he is willing to pair program with people as needed. We could move one of this projects (slave health, buildapi, slavealloc) as a start, depending on what you think is most useful. https://docs.mozilla-releng.net/.
• Priorities update. Lawrence had a meeting with his mgmt team in Toronto recently and established the following ordered priorities
  • 1. Data centre move - two different data centres (will ask Amy for plan)
  • 2. OSX on TC (we need to do this so we don’t have to move mac builders into new DC)
  • 3. Quantum
  • 4. Security, Disaster recovery (part of having two data centres now). Securing the autoland pipeline
  • 5. Phase out aurora (Q1 planning)
  • 6. Reduce orange factor
  • 7. Blocking bad commits
  • 8. TC for Linux (almost done) talos needs to be done
  • 9. TC Windows

• New buidduty team member: Sebastian Păcurar (:spacurar) \o/
  • Mozilla account (?)
  • Like in our case, he’ll need access to several places:
    • AWS console
      • [alin]: done
    • Releng LDAP group
      • [alin]: done
    • Inventory
      • [alin]: should I file a bug and ask Amy to grant access? Sure!
    • Permissions for vpn_releng_group (slave loan purposes)

      • [alin]: that’s for HW Windows loaners → ask Rob about it? Yes Rob or Marco.
• Bug 1335435 - Reduce number of linux test masters in AWS
  • Disabled nagios alerts
  • Disabled 14 (out of 22) bb masters in slavealloc and performed a clean shutdown
• Bug 1334917 - Stop double-running PGO on aurora and below, where the normal build is PGO without asking for PGO
  • We are running pgo builds for both linux32/64 and linux32/64-pgo on release-stabilization branches
  • That also triggers talos tests => backlog
• Bug 1315977 - Mac build machines doing l10n repacks need python 2.7.6 or newer
  • NI Gps ,waiting for some feedback when he will return
• Bug 1332337 - migrate machine health dashboard to releng services
  • Spoke with Rok ,he answered to some other questions that I had
  • Priority is now to concentrate on migrating backend,and for that I need t
    • Use api service instead of generating json files every x minutes, like treestatus.mozilla.releng.net
    • Use the code from slaveheath.py to create api.py and api.yml
    • Test this without using the database and when is finish see with Rok how can we take informations from the databases
• Bug 1336074
  • Question about taskcluster
    • Jobs (https://treeherder.mozilla.org/logviewer.html#?job_id=73887909&repo=mozilla-inbound&lineNumber=1414) - failed
    • Log - (https://treeherder.mozilla.org/logviewer.html#?job_id=73887909&repo=mozilla-inbound&lineNumber=1414)
    • Similar tests were made on bc4 and bc5 and were successfully, the problem on these seems to be the missing of some requirements (example No matching distribution found for blessings>=1.3 (from mozlog==3.4) but the sames steps are made on other workers, so if the steps are the same,is there something different on the workers?
