Problem/Motivation

RequestCloseSubscriber::onTerminate calls the global system_run_automated_cron function. This may backfire on lean requests, i.e whenever drupal is not bootstrapped fully.

Proposed resolution

Turn system_run_automated_cron into its own proper subscriber for the KernelEvents::TERMINATE event.

    let's add another pair of braces around REQUEST_TIME - $cron_list, to be sure it works as we want.

Thanks for the review.

Is there a reason this is not part of core but part of system module?

I feel that it should be part of the module because it accesses configuration defined by the module (system.cron / threshold.autorun).

It would be also nice if it would be part of a "EventSubscriber" namespace, just for consistency.

Yes indeed. I saw Drupal\system\SystemConfigSubscriber and was mislead into doing it like that one. That is probably not the best example.

Let's just replace those convoluted conditions with something which is more readable.

I still think we should do #1599622: Run poormanscron via a non-blocking HTTP request but this is good clean-up independent of that issue.

Committed/pushed to 8.x, thanks!
