merged 1 commit into from Jul 20, 2018

@zvkemp zvkemp commented Jun 20, 2018


Instead of firing an event after enqueuing a job, wrap the enqueue in an ActiveSupport::Notifications instrumentation block.

Other Information

Enables more accurate timing, as it includes time spent writing jobs to the adapter's IO implementation.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

This repository is being automatically checked for code quality issues using Code Climate. You can see results for this analysis in the PR status below. Newly introduced issues should be fixed before a Pull Request is considered ready to review.

Nice, thanks! Needs a rebase because of the changelog, then I'll merge.

around_enqueue do |job, block|
key = job.scheduled_at ? "enqueue_at" : "enqueue"
ActiveSupport::Notifications.instrument "#{key}.active_job",
adapter: job.class.queue_adapter, job: job, &block

Can we keep the old flow? Don't think this needs to be super-DRY.

Sorry for digging up this PR, but can we revisit this decision? The main problem with an around_callbacks and passing the block to the instrumenter is that if the enqueuing fails (i.e. redis is down), we still get the regular log message from Rails "Enqueued BlablaJob..."

That's because the instrumenter will always dispatch the notification no matter if the block raised
