Fixed a few bugs, and made numerous improvements. Fixed issue where a sync chunk load could have its ticket removed and the priority ticket could expire... Still not perfect there but better than before. Also fixed few other misc issues such as watchdog cpu usage, chunk queue update had risk of double enqueue due to it no longer being a set. Added much more information about chunk state to watchdog prints. I see some more room for improvement even, but this is much better than before. Fixes #3407 Fixes #3411 Fixes #3395 Fixes #3389

Subject: [PATCH] Implement Chunk Priority / Urgency System for Chunks
|
|
|
|
Mark chunks that are blocking main thread for world generation as urgent
|
|
|
|
Implements a general priority system so that chunks that are sorted in
|
|
the generator queues can prioritize certain chunks over another.
|
|
|
|
Urgent chunks will jump to the front of the line, ensuring that a
|
|
sync chunk load on an ungenerated chunk does not lag the server for
|
|
a long period of time if the servers generator queues are filled with
|
|
lots of chunks already.
|
|
|
|
This massively reduces the lag spikes from sync chunk gens.
|
|
|
|
Then we further prioritize loading order so nearby chunks have higher
|
|
priority than distant chunks, reducing the pressure a high no tick
|
|
view distance holds on you.
|
|
|
|
Chunks in front of the player have higher priority, to help with
|
|
fast traveling players keep up with their movement.
