Graceful shutdown - Githubissues

dwbutler commented 11 years ago

This pull request implements graceful shutdown for Qu workers. I needed to make the change because when a worker aborts, it sometimes wouldn't be able to re-queue the job into the failure queue due to the Mongoid connection already being closed. So jobs would mysteriously go missing.

Features:

Optional via configuration: Qu.graceful_shutdown = true
If the worker is performing a job, waits for the job to complete before shutting down.
If the worker is blocked waiting for new jobs, Abort is raised instead to force an exit.
Specs!

Okay, I think this should do it.

The worker rake task should exit normally with code 0 if it breaks out of a sleep or exits gracefully. It will only exit abnormally with code 1 if it aborts a currently running job.

Nice! I had given up all hope on this.

@dwbutler fear not! :) Hoping to get a few more things together and cut a beta. We'll see.
