3.0: Interface for background tasks queue about smf HOT 4 OPEN

So basically we need a backlog UI that allows marking task in another queue that fast track them ahead of the currently scheduled items? Or maybe I'm missing something..

The Send Mail queue function essentially forces the mail queue to send by ignoring limits and other protections (except for timeout handling). So it would act the same. Say there are 5000 items in the queue, instead of slowly pushing out a few items at a time (let's say 60 items a minute), it would take almost 90 minutes to send all of it, it would just tell it to send it all now. Server performance may be impacted (just as sending the mail queue can do).

Seeing the queue and knowing how much is backlogged, can help admins know that adjustments need to be made to keep up with the queue.

It's a good idea, although it might need some refining. Specifically, trying to create an ability to flush the queue might not make a lot of sense. As I recall, TaskRunner already tries to complete as many tasks as it can in a single run before timing out. Trying to flush the queue wouldn't do anything more than the system already does.

We may also need some new database columns to count execution attempts and such.

Well, we need that for the mail stuff as well, so we can dump mail that isn't sending. The hack I worked into 2.1 was to work around database columns by abusing the priority column.

There is some logic though that prevents us from sending too much. Even if something is in the queue, hitting cron.php won't send it, if it just did a little while ago, at least from my basic testing.
