Wp Cron, major issue by removing the apply_filter when wp_cron() is trigged.

[ajami]

I have seen on Wordpress 4.9, they remove apply_filter($hook,$args) form wp_cron() function which will affect a lot of crons which depends on this action hook. When we schedule a event we give hook to trig while the cron is executing, now with the latest branch ( wp-4.9-branch ) this i will not happen.I hope Wordpress to make it a urgent priority and provide the patch.

Hi @ajami

I'm not sure I follow your ticket.
No filters have been removed from WordPress in the cron system recently, infact, here's all the changes to the file since WordPress 4.0.

Based on your addition of a hook to be run in cron.php, I'm going to assume you're having issues with cron running - Cron runs through the use of a loopback HTTP request which kicks off a new PHP process which the crons run in.
The code you've altered calls spawn_cron() which then loads https://core.trac.wordpress.org/browser/trunk/src/wp-cron.php#L98 and the action gets triggered there.

If you're having cron spawning problems, Trac is not a support avenue and I'd recommend the ​Support Forums.
I'm closing this report as cron hasn't had any major changes in the last 3 years, there's been no other reports of cron issues, and I've personally been using it since the release.
