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.
Locks dimension manager to the first world its used with.
WE is creating a temp world and the world ref on that manager
is getting changed to the temp world.
This would of also caused a memory leak of that temp world too.

My recent work on serialization is now in CraftBukkit so was able to drop the patch and Paper
is now consistent with upstream.

CraftBukkit Changes:
1b2830a3 SPIGOT-4441: Fix serializing Components to and from Legacy
This change reimplements the entire BehaviorFindPosition method to
get rid of all of the streams, and implement the logic in a more sane way.
We keep vanilla behavior 100% the same with this change, just wrote more
optimal, as we can abort iterating POI's as soon as we find a match....
One slight change is that Minecraft adds a random delay before a POI is
attempted again. I've increased the amount of that delay based on the distance
to said POI, so farther POI's will not be attempted as often.
Additionally, we spiral out, so we favor local POI's before we ever favor farther POI's.
We also try to pathfind 1 POI at a time instead of collecting multiple POI's then tossing them
all to the pathfinder, so that once we get a match we can return before even looking at other
POI's.
This benefits us in that ideally, a villager will constantly find the near POI's and
not even try to pathfind to the farther POI. Trying to pathfind to distant POI's is
what causes significant lag.
Other improvements here is to stop spamming the POI manager with empty nullables.
Vanilla used them to represent if they needed to load POI data off disk or not.
Well, we load POI data async on chunk load, so we have it, and we surely do not ever
want to load POI data sync either for unloaded chunks!
So this massively reduces object count in the POI hashmaps, resulting in less hash collions,
and also less memory use.
Additionally, unemployed villagers were using significant time due to major ineffeciency in
the code rebuilding data that is static every single invocation for every POI type...
So we cache that and only rebuild it if professions change, which should be never unless
a plugin manipulates and adds custom professions, which it will handle by rebuilding.
Due to some complexity in mojangs complicated chain of juggling
whether or not a chunk should be unloaded when the last ticket is
removed, many chunks are remaining around in the cache.
These chunks are never being targetted for unload because they are
vastly out of view distance range and have no reason to be looked at.
This is a huge issue for performance because we have to iterate these
chunks EVERY TICK... This is what's been leading to high SELF time in
Ticking Chunks timings/profiler results.
We will now detect these chunks in that iteration, and automatically
add it to the unload queue when the chunk is found without any tickets.
2 people had issues where some plugin is doing some reallly insane NMS hackery
that created invalid worlds, which caused some errors...
Really don't understand what in the world they did, but putting in a dumb guard that
shouldn't even be necessary to just not send the sound effect rather than erroring.
Instead of using the entire world or player list, use the distance
maps to only iterate players who are even seeing the chunk the packet
is originating from.
This will drastically cut down on packet sending cost for worlds with
lots of players in them.
Closes#3437
Fixed issues where urgent and prioritized chunks didn't actually
always get their priority boosted correctly....
Properly deprioritize non ticking chunks.
Limit recursion on watchdog prints to stop flooding as much
Remove neighbor priorities from watchdog to reduce information
reduce synchronization duration so that watch dog won't block main should main actually wake up
probably fixed a deadlock risk in watchdog printing also that was leading to crashes
fixed chunk holder enqueues not being processed correctly
added async catchers in some locations that should not be ran async
Fixed upstream bug where VITAL callbacks that must run on main actually could
sometimes run on the server thread pool causing alot of these nasty bugs we've seen lately!
This build will provide massive improvements to stability as well as even faster
sync chunk load/gens now that priority is correctly set.
Fixes#3435
synchronized arraydeque ends up still being way faster.
Kinda shocked how much that strategy was using, it wasn't really
that complicated... but oh well, this is even simpler and not
seeing blocked threads show up at all in profiling because
the lock is held for such a short amount of time.
also because most uses are on either server thread pool or chunk load pool.
Also optimize the pooling of nibbles to not register Cleaner's
for Light Engine directed usages, as we know we are properly
controlling clean up there, so we don't need to rely on GC.
This will return them to the pool manually, saving a lot of Cleaners.
Closes#3417
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)
This commit doesn't do much on its own, but adds a new Java Cleaner API
that lets us hook into Garbage Collector events to reclaim pooled objects and
return them to the pool.
Adds framework for Network Packets to know when a packet has finished dispatching
to get an idea when a packet is done sending to players.
Rewrites PooledObjects impl to properly respect max pool size and remove
almost all risk of contention.
Bumps the Paper Async Task Queue to use 2 threads, and properly shuts it down on shutdown.

Undo the accidental renaming of a method in 0aad8bf
Aikar wanted to rename DataPalette#getDataBits(T object) to getOrCreateIdFor
in 0aad8bf but he also accidentally renamed
ChunkPacketInfo#getDataBitsIndex(int chunkSectionIndex) to
getOrCreateIdForIndex.
Remove chunk-edge-mode and chunk loading entirely from Anti-Xray
The chunk-edge-mode is broken since several versions.
Loading chunk neighbors for chunk edge obfuscation isn't needed anymore.
Unlike in previous versions, these are under normal circumstances already loaded
at the time we need them (plugins for example can bypass this).
Use the modified methods and constructors everywhere
Anti-Xray provides support for the default nms methods and constructors,
which where modified by Anti-Xray to avoid breaking stuff (plugins)
which somehow uses these methods.
However, the modified versions of those methods and constructors should be used
where possible.

also fire the callback using executor incase further recursion causes any trouble
The streams hurt performance and allocate tons of garbage, so
replace them with the standard iterator.
Also optimise the stream.anyMatch statement to move to a bitset
where we can replace the call with a single bitwise operation.
