# Description This PR implements an experimental inter-job communication model, through direct message passing, aka "mail"ing or "dm"ing: - `job send <id>`: Sends a message the job with the given id, the root job has id 0. Messages are stored in the recipient's "mailbox" - `job recv`: Returns a stored message, blocks if the mailbox is empty - `job flush`: Clear all messages from mailbox Additionally, messages can be sent with a numeric tag, which can then be filtered with `mail recv --tag`. This is useful for spawning jobs and receiving messages specifically from those jobs. This PR is mostly a proof of concept for how inter-job communication could look like, so people can provide feedback and suggestions Closes #15199 May close #15220 since now jobs can access their own id. # User-Facing Changes Adds, `job id`, `job send`, `job recv` and `job flush` commands. # Tests + Formatting [X] TODO: Implement tests [X] Consider rewriting some of the job-related tests to use this, to make them a bit less fragile. # After Submitting |
