Effect or LevelEvent needs to be replaced
but ideally after the enum PR has been merged
upstream. Until then, this test and these fixes
should address all the known issues with them
Spigot incorrectly instanceOf checks the EntityTargetEvent#getTarget
against the internal ItemEntity type and removes the nearest wanted item
memory if said instanceOf check fails, (which is always the case)
causing allays to behave differently as they constantly lose their
target item.
This commit fixes the faulty behaviour by instance performing a check
against the CraftItem type.
Pulling Folia API to Paper is primarily intended for plugins
that want to target both Paper and Folia without unnecessary
compatibility layers.
Add both a location based scheduler, an entity based scheduler,
and a global region scheduler.
Owned region API may be useful for plugins which want to perform
operations over large areas outside of the buffer zone provided
by the regionaliser, as it is not guaranteed that anything
outside of the buffer zone is owned. Then, the plugins may use
the schedulers depending on the result of the ownership check.
When selecting which explosion resistance to use for lava and water, vanilla selects the highest value between their block explosion resistance and fluid explosion resistance.
Problems emerge when we want to reduce the explosion resistance of water or lava, since the fluid explosion resistance is hardcoded to return 100.0F and can't be changed by a plugin. This simply makes the fluid explosion resistance the same as the block explosion resistance, which allows plugin to change the value. Since both are the same in vanilla, this has no side effects on servers that do not need to do this.
In the event that an item frame cannot be seen by any players, ticking the item frame every tick is unnecessary. This can be a very hot section of the entity tracker when lots of item frames are present on a server, so this reduces the logic which speeds it up.
Fix several issues when a player interact with a block:
* the place sound isn't played for the dispensed shulker block
* desync of the jukebox blocks between bukkit handler and the vanilla interaction
* poi can desync when the BlockPhysicsEvent is cancelled
Makes sure the value returned by Projectile#getShooter in
the API matches the owner UUID specified in the entity nbt.
Previously, after the entity reloaded, Projectile#getShooter
would return null, while the entity still had an owner.
Also fixes setting the shooter/owner to null actually
clearing the owner.

For fishing hooks, the openWater field is true by default, and only calculated when a "fish" is approaching the bobber.

This patch is meant to get rid of any instances of lazy initialization that Minecraft introduces for enums.
This has the possibility to create race condition issues, and generally don't make sense to be lazily done anyways.
Upstream incorrectly skipped explosion logic if

if you set your spawn in a respawn anchor world
but then replaced it with a bed, you could respawn
at the bed in that world.

Changes the Interaction entity's trigger to use the vanilla
generic damage source
Fixes a couple places where the original damage and modified damage
were passed in the reverse order to the advancement triggers
This creates a problem with Paper's item serialization
api where deserialized items, which are internally
created as a CraftItemStack, will be completely lost if
#setAmount(0) is invoked (since the underlying handle
is set to null), while a regular Bukkit ItemStack
simply sets the amount field to zero, retaining the
item's data.
Vanilla treats items with zero amounts the same as items
with less than zero amounts, so this code doesn't create
a problem with operations on the vanilla ItemStack.
The EntityResurrectEvent logic is supposed to locate a totem of undying
in any of the interaction slots of the player inventory and then, if the
called EntityResurrectEvent is not cancelled, shrink that item by 1,
usually reducing it to zero.
For this, the logic iterates over the items in the interaction slots and
breaks out the loop if a totem of undying was found.
However, even if no totem of undying was found, the iteration item stack
variable remains as a refernce to the last interaction slot probed.
Plugins uncancelling a EntityResurrectEvent, which is published
pre-cancelled to listeners if no totem of undying could be found,
would hence cause the server logic to shrink completely unrelated items
found in, at the writing of this patch, the players off hand slot.
This patch corrects this behaviour by only shrinking the item if a totem
of undying was found and the event was called uncancelled.
Menus don't add slots for the offhand, so on sendAllDataToRemote calls the
offhand slot isn't sent. This is not correct because you *can* put stuff into the offhand
by pressing the offhand swap item
When the server is stopping, the default execution handler method will throw a

By default, spigot shifts chat over to an unbounded thread pool,
on a normal server, this really offers no gains, the creation of a thread
on submitting to the pool on these servers eats more time vs just running it in
the netty pipeline, however, on servers using plugins which do work in here, there
could be some overall benefits to moving this stuff outside of the pipeline.
In general, this patch does two things:
1) Exposes the core size for the pool, this allows for ensuring that a number of threads
sit around in the pool, mitigating the need for creating new threads; This IS however
caveated, the ThreadPoolExecutor will ONLY create core threads as they're needed, it
just won't allow for us to dip back under the # of core threads, this can potentially
be mitigated by calling prestartCoreThread, however, I'm not sure if there is much justification
for this
2) Exposes a max size for the pool, as stated, by default this is unbounded, for most
servers limiting the size of the pool is going to have 0 effects given how fast chat
is actually processed, this is honestly really just exposed for the misnomers or people
who just wanna ensure that this won't grow over a specific size if chat gets stupidly active
While Velocity supports BungeeCord-style IP forwarding, it is not secure. Users
have a lot of problems setting up firewalls or setting up plugins like IPWhitelist.
Further, the BungeeCord IP forwarding protocol still retains essentially its original
form, when there is brand new support for custom login plugin messages in 1.13.
Velocity's modern IP forwarding uses an HMAC-SHA256 code to ensure authenticity
of messages, is packed into a binary format that is smaller than BungeeCord's
forwarding, and is integrated into the Minecraft login process by using the 1.13
login plugin message packet.
Beyond calling the BlockFadeEvent in more places, this patch also aims
to pass the proper replacement state to the event, specifically for
potentially waterlogged block states fading.

Minecraft's prediction system does not handle block entities, so if we are manually sending block entities during
block breaking we need to set it after the prediction is finished. This fixes block entities not showing when cancelling the BlockBreakEvent.
Paper makes the entity random thread-safe
and constructing an entity off the main thread
should be supported. Some entities (for whatever
reason) use the level's random in some places.
These can be called while an entity is being added to the world,
and if the entity is being added from a chunk load context the
sync load will block indefinitely (because the chunk load context
is for completing the chunk to FULL).
This does raise questions about the current system for these
dynamic registrations, as it looks like there is _zero_ logic
to account for the case where the chunk is _not_ currently loaded
and then later loaded.
The previous solution caused a bunch of bandaid fixes inorder to resolve edge cases where minecraft/the api might spawn items that are air.
Just simply prevent them from being added to the world instead.
Craftbukkit attempts to translate worlds that use the
same generation as the Overworld, The Nether, or The End
to use those dimensions when checking the `changed_dimension`
criteria trigger, or whether to trigger the `NETHER_TRAVEL`
distance trigger. This adds a config option to ignore that
and use the exact dimension key of the worlds involved.
When calling getBedSpawnLocation on an
instance of CraftOfflinePlayer the world was incorrect
due to the logic for reading the NBT not being up-to-date.

Fixes https://github.com/PaperMC/Paper/issues/7276 and https://github.com/PaperMC/Paper/issues/8118
by using a config option that, when set to false, does not add markers to the entity
tick list at all and ignores them in Spigot's activation range checks. The entity tick
list is only used in the tick and tickPassenger methods, so we can safely not add the
markers to it. When the config option is set to true, markers are ticked as normal.
By checking if the world passed into StructureTemplate's placeInWorld
is not a WorldGenRegion, we can bypass the deadlock entirely.
See https://bugs.mojang.com/browse/MC-246262
Also standardizes how to handle EntityChangeBlockEvent before a removeBlock or destroyBlock
call. Always use 'state.getFluidState().createLegacyBlock()' to get the new state instead of
just using the 'air' state.
Also fixes the new block data for EntityBreakDoorEvent (a sub-event from
EntityChangeBlockEvent)

lets debug mode throw a trace in order to potentially see where
such calls are cascading from easier, but, generally, if you see one setBlock
call, you're gonna see more, and this just potentially causes a flood of logs
which can cause issues for slower terminals, etc.
We can limit the flood by just allowing one for a single gen region,
we'll also only gen a trace for the first one, I see no real pressing need
to generate more, given that that would *massively* negate this patch otherwise
The worldgen thread will attempt to get structure references
via the world's getChunkAt method, which is fine if the gen is
not cancelled - but if the chunk was unloaded, the call will block
indefinitely. Instead of using the world state, we use the already
supplied ServerLevelAccessor which will always have the chunk available.

Piercing arrows search for multiple entities inside a while
loop that is checking the projectile entity's removed state.
If the hit event is cancelled on the first entity, the event will
be called over and over again inside that while loop until the event
is not cancelled. The solution here, is to make use of an
already-existing field on AbstractArrow for tracking entities hit by
piercing arrows to avoid duplicate damage being applied.

Dead players would be stuck in the world loading screen and other players may
miss messages and similar sent in the join event if chunk loading is slow.
Paper already circumvents falling through the world before chunks are loaded,
so we do not need that. The client only needs the chunk it is currently in to
be loaded to close the loading screen, so we just send an empty one.
By default, only LevelStem's that specifically match the ResourceKey for
OVERWORLD will have the 5 (currently) impls of CustomSpawner (for
phantoms, wandering traders, etc.). This adds an option to instead of
just looking at the LevelStem key, look at the DimensionType key which
is one level below that. Defaults to off to keep vanilla behavior.
General purpose patch adding missing getters/setters to BlockData and
its child types.
