• Fairly gnarly toolbar bug - 142.0.1 went out today.
• Let’s keep going with the tool we wrote! I made some changes. I’ve copied over the TODOs from last week.
• TODO:
  • Query GitHub for the most recent revision SHA.
    • http “https://api.github.com/repos/mozilla-firefox/firefox/commits?sha=main&perpage=1&page=1”
  • Check to see if the Mercurial mapping is in the local cache.
    • If not, ask this tool for a mapping to the Mercurial SHA
  • Use the Mercurial SHA and ask Taskcluster JS library for train-hop job status
    • Hit https://treeherder.mozilla.org/api/project/mozilla-central/push/?full=true&count=10&revision=[Mercurial SHA] to get back job description
    • Extract push id from description (it’s the id value), and then request all jobs
    • Query https://treeherder.mozilla.org/api/jobs/?pushid=[push id]&jobgroupsymbol=nt-trainhop
    • That should give us the pass/fail on the trainhop jobs. Check for repeat platforms to detect intermittents.
