In previous MC versions, we had a rather simple internal scheduler for delayed tasks that would just keep pushing task back until desired tick was reached. The method it called to schedule the task changed behavior in 1.14, and now this scheduler is not working nowhere near what it was supposed to be doing. This was causing long delayed task to eat up CPU (In Oversleep for example) Rewrite this to just use the CraftScheduler for scheduling delayed tasks. Once this was fixed, it became quite clear the code that delayed ticket additions for chunks based on distance was clearly not right, as it was tested on the previous broken logic. So the ticket delay process has been vastly revamped to be even smarter. Chunks behind the player can load slower than the chunks in front of the player. We also can delay ticket adding until one of its neighbors has loaded, as this lets us get a smoother spiral out for the chunks (minus frustum intent). Additionally on frustum previous commit inadvertently broke frustum trying to fix an issue when the real fix lied elsewhere, so restore chunk priority so it works again.

Subject: [PATCH] Remove CraftScheduler Async Task Debugger
|
|
|
|
I have not once ever seen this system help debug a crash.
|
|
One report of a suspected memory leak with the system.
|
|
|
|
This adds additional overhead to asynchronous task dispatching
