The server validates incoming interaction packets by ensuring the player
sending them is inside their interaction range. For this, the server adds
a magic value, by default 1.0, to the original interaction range to
account for latency issues.
This value however may be too low in high latency environments.
The patch exposes a new configuration option to configure said value.
Long ago we discovered that the default thread pools would not increase
the number of threads running the pool until queue addition failed.
Bumping the core size mitigates an issue with spark-paper, and in general,
keeping async threads around generally beats having to spin new ones
everytime we want to execute a periodic async task.
what paper now shows as level loading time is the time displayed by vanilla or spigot in the 'done' message
the time in the done message is now the actual time since the servers Main class was initialized

We don't need to check for this with the chunk system, as
ticking chunks are actually guaranteed to ticking. Additionally,
ticking chunks may only become non-ticking during the chunk holder
manager tick - which will not happen during chunk ticking.
In Java 21, Thread#stop is no longer implemented and wiill throw
an exception when called. As a result, we simply cannot halt
the main thread during shutdown anymore.
A general set of bugfixes for itemstack damage related logic.
1. Prevent NPE when calling deprecated ItemStack#getMaxItemUseDuration()
2. Do not apply enchantments when damaging items via API
3. Do not error when passing a null equipment slot to hurtAndBreak
4. Correctly call PlayerItemBreakEvent
Only skip the damage tick logic on player entities if the original
damage was zero and was not modified by plugins down the line.
This way all the following three scenarios trigger the damage tick
a) vanilla damage was 0, plugin set it to non zero
b) vanilla damage was non zero, plugin did not modify it
c) vanilla damage was non zero, plugin set it to zero.
Regarding case c, the argument here is that EntityDamageEvent#setDamage
should not modify the damage tick logic.
When teleporting, the spawn position packet will contain the
old position. Then the following tracking update will send a
teleport packet, but the client will lerp the position change
over 3 ticks. However, the client does not tick entities in
unloaded chunks - resulting in the lerp never occuring.
We fix this by sending the current position in the spawn packet.
Since the chunk may not even be at a loaded ticket level, the
getChunk call may invoke a sync load. To prevent this, we can
retrieve the full loaded chunk first which is guaranteed to be
non-null when unloading.
The recent upstream update moved around the event logic for
EntiyDamageEvent and its derivatives.
However, the event was called on every call to #hurt as it was moved out
of actuallyHurt.
This patch moves the invocation directly before the #actuallyHurt calls,
respective invulnerable timings.
The logic in place to prevent players from processing a damage
tick/knockback/etc when hit with 0 damage incorrectly used the damage
events final damage value, which is reduced by absorption.
Instead, use the event's "raw damage", e.g. the amount passed to hurt,
in order to determine if the damage tick should be skipped.
This still allows plugins to change the damage to a non-zero value and
properly damage ticks the player in such a case, but correctly processes
the damage tick in cases where the original damage is non zero but the
actual damage is.

If the server tick length is high, then the amount of time
available to process chunk tasks inbetween ticks is low. As a
result, chunk loading and generation may appear to slow down.
To ensure that chunk tasks are always processed, we add logic to
execute chunk tasks during tile entity tick, entity tick, chunk
random ticking, and scheduled block/fluid ticking. The mid-tick task
execution is timed so that it is not prioritised over the server
tick.
While the null UUID is almost certainly an error, the old
implementation did not NPE as it used a plain HashMap for lookup
by UUID, whereas we use a ConcurrentHashMap which will NPE on
null keys.
The unload queue stored the chunks in the same section as
the chunk coordinate, when it needed to apply the unload shift.
Additionally, change the default region shift to the ticket
propagator shift as there is no benefit to using a low region
shift since no regionizing is occuring. This makes the unload
queue shift 6, which should reduce the number of sections to deal
with while processing unloads.
Somehow, a chunkholder is present in the unload queue after
it has been unloaded. It is likely that this is a result of
adding the chunk holder to the unload queue while it is
unloading. However, that should not be possible.
To find out where it is being added to the unload queue, track
the last stacktrace which adds to the unload queue and check
on chunk holder remove if the holder is present in the unload queue
and log the stacktrace.
Remove utilities that are unused, as well as replacing
the full chunk map with a concurrentutil implementation.
Additionally, fix the addition/removal of chunks to/from the
full chunk map so that getChunkIfLoaded correctly returns a
non-null chunk when calling the load or unload events.
The upstream implementation is returning true for non-full chunks.
This fix is not ideal since the new chunk system doesn't have a region file/chunk status patch. May want to be revisited before a non-experimental release.
Implementations for ChunkStatuses below FULL are supposed to always
return ProtoChunk instances. However, since we used the last completed
status, it could return LevelChunk.
To resolve this, follow Vanilla behavior of tracking chunk
completions by status and replace old ProtoChunk statuses with
ImposterProtoChunk when the chunk generates to FULL.
Additionally, implement an optimisation for retrieving full chunks
by storing a map of pos -> LevelChunk. This requires only a simple
map lookup to occur for full chunks which are loaded.

The method sadly is not usable in 1.21 without a player as all of an
enchantments attribtue modifiers rely on a base value supplied by a
player. The method could only offer a rough estimate based on some
default values, however a better method for this should be added down
the line rather than trying to force such logic into the existing one.
A long standing bug in spigot and its derivatives was the fact that
players taking damage while blocking with a shield would not receive
invulnerability, while they do in vanilla.
This enabled the pvp technique of disabling a shield and immediately
attacking again to knock a player into the air.
While upstream fixed this and properly aligned itself with vanilla
damage logic (in this specific case) changing such long standing
behaviour has some downsides.
To allow players used to this specific bug to still use it, this patch
introduces a configuration option to re-introduce said bug.
As there is no easy way to *only* re-add this bug, the option is found
in the unsupported section as it may introduce other damage related
disparity from vanilla.
Previously would stream and optionally filter out all entries in the
enchantment registry.
Moves it to using the empty optional if treasure is allowed, leaving the
logic to EnchantmentHelper.
