A pulse listener that acts upon messages with mozci.

Project description

This project is Pulse listener that listens to Treeherder’s job cancellation and retrigger actions in ‘exchange/treeherder/v1/job-actions’ and acts upon them.

What it does

  • listens to exchange/treeherder/v1/job-actions in an infinite loop.
  • When it sees a retrigger actions it makes a retrigger request in builapi self-serve using make_retrigger_request from mozci.
  • When it sees a cancel action it makes a cancel request in buildapi self-serve using make_cancel_request from mozci.
  • Currently everything is run with dry_run=True, so instead of doing requests the script just logs the requests it would have made.

Current status

  • reads exchange and topic from run_time_config.json. It then uses HANDLERS_BY_EXCHANGE, a dictionary defined in to decide what function it will use to handle incoming messages.
  • Only buildbot topics (e.g. buildbot.#.# or buildbot.try.retrigger) in exchange/treeherder/v1/job-actions are supported for now.
  • The functions to deal with TH’s job-actions are defined in the module


  • mozci
  • mozillapulse
