Add action hook after cron processed it's jobs

[tott]

Sometimes it's hard to debug cron jobs or validate the results. A simple action fired after the wp-cron.php did his magic could help improve this experience.

Add action hook to wp-cron.php

#22143 was marked as a duplicate.

I guess using the 'shutdown' hook wouldn't do, since you would want access to the jobs just completed.

How about calling the hook 'did_cron' instead?

Added patch from #22143; it fires the action immediately after the event has executed and passes in some args specific to that event.

I found myself wanting a hook like this too. The shutdown hook was a little too late for my application (and I wouldn't want my code to step on the feet of other shutdown code)

I too would like this functionality. Anyone know what the next closest hook is in the flow of loading things?

This patch is an update to @batmoo with documentation added so it can be pushed in a future release. I changed the last parameter from $v to $v['args'] because we shouldn't need to return the results of wp_reschedule_event() (which modifies $v specifically for rescheduling).

I left out @since from the comment as I wasn't sure when this would be added.

Also just referencing this is for Contributor Day at WordCamp US 2015! :)

Mentioning here as well: #28635 is probably the better method which adds many more hooks and adds an exit handler.

Closing this off in favour of #28635
