Spigot still maintains some partial implementation of "tick skipping", a
practice in which the MinecraftServer.currentTick field is updated not
by an increment of one per actual tick, but instead set to
System.currentTimeMillis() / 50. This behaviour means that the tracked
tick may "skip" a tick value in case a previous tick took more than the
expected 50ms.
To compensate for this in important paths, spigot/craftbukkit
implements "wall-time". Instead of incrementing/decrementing ticks on
block entities/entities by one for each call to their tick() method,
they instead increment/decrement important values, like
an ItemEntity's age or pickupDelay, by the difference of
`currentTick - lastTick`, where `lastTick` is the value of
`currentTick` during the last tick() call.
These "fixes" however do not play nicely with minecraft's simulation
distance as entities/block entities implementing the above behaviour
would "catch up" their values when moving from a non-ticking chunk to a
ticking one as their `lastTick` value remains stuck on the last tick in
a ticking chunk and hence lead to a large "catch up" once ticked again.
Paper completely removes the "tick skipping" behaviour (See patch
"Further-improve-server-tick-loop"), making the above precautions
completely unnecessary, which also rids paper of the previous described
incompatibility with non-ticking chunks.

map data files as being dirty even if nothing has actually changed.

In the recent upstream update, the paper player profile was updated to
correctly return null for both name and id if constructed as such. This
change however broke the serialisation logic, as it depended on the name
never being null.
The commit moves the checks over to the newly introduced emptyName/UUID
fields that track if the profile was constructed with a null name or
uuid to differentiate it against an empty string or the NIL_UUID.
Upstream has released updates that appear to apply and compile correctly.

The updated velocity native compilation pipeline seems to emit binaries
that are not compatible with alpine.
The commit temporarily reverts the natives included until a proper
solution is found.
In the case where multiple messages from different players are being processed in parallel, there was a potential race condition where the messages would be sent to the client in a different order than the message signature cache was updated. However, the cache relies on the fact that the client and server get the exact same updates in the same order. This race condition would cause the caches to become corrupted, and any future message received by the client would fail to validate.
This also applies to the last seen state of the server, which becomes inconsistent in the same way as the message signature cache and would cause any messages sent to be rejected by the server too.
When trying to fall back to offline player data in onlide mode,
we need to use the player file. This fixes a mistake during
update where 'file' was used, but the new code uses 'file1'
for the player file.

Mojang missed these in their mapping. Since the entity data
is used when spawning the bucketed mob, we need to have these
inside the id map to ensure that the entity data is converted
correctly if the entity id is missing.
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

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.
Prevent a IOB exception when querying topic
suggestions on query string `/`.
Additionally hide help topics indices if no topics
are visible to the player requesting them.
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.

API does not appear to be used, and it is a real pain to
implement this properly. The old patch did not handle
populators correctly, for example.
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.
