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. This commit also improves single core cpu scenarios in that we will now automatically disable Async Chunks as well as Minecrafts thread pool. It is never recommended to use async chunks on a single CPU as context switching will be slower than just running it all on main. This also bumps the number of server worker threads by default too. Mojang does not utilize the workers in an effecient manner, resulting in them using barely any sustained CPU. So give it more workers so more chunks can be processed concurrently This change also improves urgent chunk loading, so players flying into unloaded chunks will hurt a little bit less (but still hurt) Ping #3395 #3363 (Not marking as closed, we need to make prevent moving work)

Subject: [PATCH] Protect Bedrock and End Portal/Frames from being destroyed
|
|
|
|
This fixes exploits that let players destroy bedrock by Pistons, explosions
|
|
and Mushrooom/Tree generation.
|
|
|
|
These blocks are designed to not be broken except by creative players/commands.
|
|
So protect them from a multitude of methods of destroying them.
|
|
|
|
A config is provided if you rather let players use these exploits, and let
|
|
them destroy the worlds End Portals and get on top of the nether easy.
