Subject: [PATCH] Break up and make tab spam limits configurable
Due to the changes in 1.13, clients will send a tab completion request
for all bukkit commands in order to factor in the lack of support for
brigadier and provide backwards support in the API.
Craftbukkit, however; has moved the chat spam limiter to also interact
with the tab completion request, which while good for avoiding abuse,
causes 1.13 clients to easilly be kicked from a server in bukkit due
to this. Removing the spam limit could cause issues for servers, however,
there is no way for servers to manipulate this without blindly cancelling
kick events, which only causes additional complications. This also causes
issues in that the tab spam limit and chat share the same field but different
limits, meaning that a player having typed a long command may be kicked from
the server.
Splitting the field up and making it configurable allows for server owners
to take the burden of this into their own hand without having to rely on
plugins doing unsafe things.

Subject: [PATCH] Use ConcurrentHashMap in JsonList
This is specifically aimed at fixing #471
Using a ConcurrentHashMap because thread safety
The performance benefit of Map over ConcurrentMap is negligabe at best in this scenaio, as most operations will be get and not add or remove
Even without considering the use-case the benefits are still negligable
Original ideas for the system included an expiration policy and/or handler
The simpler solution was to use a computeIfPresent in the get method
This will simultaneously have an O(1) lookup time and automatically expire any values
Since the get method (nor other similar methods) don't seem to have a critical need to flush the map to disk at any of these points further processing is simply wasteful
Meaning the original function expired values unrelated to the current value without actually having any explicit need to
The h method was heavily modified to be much more efficient in its processing
Also instead of being called on every get, it's now called just before a save
This will eliminate stale values being flushed to disk
Modified isEmpty to use the isEmpty() method instead of the slightly confusing size() < 1
The point of this is readability, but does have a side-benefit of a small microptimization

Subject: [PATCH] Improve death events
This adds the ability to cancel the death events and to modify the sound
an entity makes when dying. (In cases were no sound should it will be
called with shouldPlaySound set to false allowing unsilencing of silent
entities)
It makes handling of entity deaths a lot nicer as you no longer need
to listen on the damage event and calculate if the entity dies yourself
to cancel the death which has the benefit of also receiving the dropped
items and experience which is otherwise only properly possible by using
internal code.
TODO 1.17: this needs to be checked (actually get off your lazy ass and cancel the events) for the following entities,
maybe more (please check patch overrides for drops for more):
- players, armor stands, foxes, chested donkeys/llamas

Subject: [PATCH] Catch JsonParseException in Entity and TE names
As a result, data that no longer parses correctly will not crash the server
instead just logging the exception and continuing (and in most cases should
fix the data)
Player data is fixed pretty much immediately but some block data (like
Shulkers) may need to be changed in order for it to re-save properly
No more crashing though.

Subject: [PATCH] Call player spectator target events and improve
implementation
Use a proper teleport for teleporting to entities in different
worlds.
Implementation improvements authored by Spottedleaf <Spottedleaf@users.noreply.github.com>
Validate that the target entity is valid and deny spectate
requests from frozen players.
Also, make sure the entity is spawned to the client before
sending the camera packet. If the entity isn't spawned clientside
when it receives the camera packet, then the client will not
spectate the target entity.

Say a player shoots an arrow through a nether portal, the game
would lose the shooter for determining things such as Player Kills,
because the entity is in another world.
If the projectile fails to find the shooter in the current world, check
other worlds.

Subject: [PATCH] Improve Server Thread Pool and Thread Priorities
Use a simple executor since Fork join is a much more complex pool
type and we are not using its capabilities.
Set thread priorities so main thread has above normal priority over
server threads
Allow usage of a single thread executor by not using ForkJoin so single core CPU's.

Subject: [PATCH] force entity dismount during teleportation
Entities must be dismounted before teleportation in order to avoid
multiple issues in the server with regards to teleportation, shamefully,
too many plugins rely on the events firing, which means that not firing
these events caues more issues than it solves;
In order to counteract this, Entity dismount/exit vehicle events have
been modified to supress cancellation (and has a method to allow plugins
to check if this has been set), noting that cancellation will be silently
surpressed given that plugins are not expecting this event to not be cancellable.
This is a far from ideal scenario, however: given the current state of this
event and other alternatives causing issues elsewhere, I believe that
this is going to be the best soultion all around.
Improvements/suggestions welcome!

Subject: [PATCH] Add PlayerConnectionCloseEvent
This event is invoked when a player has disconnected. It is guaranteed that,
if the server is in online-mode, that the provided uuid and username have been
validated.
The event is invoked for players who have not yet logged into the world, whereas
PlayerQuitEvent is only invoked on players who have logged into the world.
The event is invoked for players who have already logged into the world,
although whether or not the player exists in the world at the time of
firing is undefined. (That is, whether the plugin can retrieve a Player object
using the event parameters is undefined). However, it is guaranteed that this
event is invoked AFTER PlayerQuitEvent, if the player has already logged into
the world.
This event is guaranteed to never fire unless AsyncPlayerPreLoginEvent has
been called beforehand, and this event may not be called in parallel with
AsyncPlayerPreLoginEvent for the same connection.
Cancelling the AsyncPlayerPreLoginEvent guarantees the corresponding
PlayerConnectionCloseEvent is never called.
The event may be invoked asynchronously or synchronously. As it stands,
it is never invoked asynchronously. However, plugins should check
Event#isAsynchronous to be future-proof.
On purpose, the deprecated PlayerPreLoginEvent event is left out of the
API spec for this event. Plugins should not be using that event, and
how PlayerPreLoginEvent interacts with PlayerConnectionCloseEvent
is undefined.

Subject: [PATCH] Add APIs to replace OfflinePlayer#getLastPlayed
Currently OfflinePlayer#getLastPlayed could more accurately be described
as "OfflinePlayer#getLastTimeTheirDataWasSaved".
The API doc says it should return the last time the server "witnessed"
the player, whilst also saying it should return the last time they
logged in. The current implementation does neither.
Given this interesting contradiction in the API documentation and the
current defacto implementation, I've elected to deprecate (with no
intent to remove) and replace it with two new methods, clearly named and
documented as to their purpose.

Subject: [PATCH] Block Entity#remove from being called on Players
This doesn't result in the same behavior as other entities and causes
several problems. Anyone ever complain about the "Cannot send chat
message" thing? That's one of the issues this causes, among others.
If a plugin developer can come up with a valid reason to call this on a
Player we will look at limiting the scope of this change. It appears to
be unintentional in the few cases we've seen so far.

Subject: [PATCH] BlockDestroyEvent
Adds an event for when the server is going to destroy a current block,
potentially causing it to drop. This event can be cancelled to avoid
the block destruction, such as preventing signs from popping when
floating in the air.
This can replace many uses of BlockPhysicsEvent

Subject: [PATCH] Async command map building
This adds a custom pool inorder to make sure that they are closed
without much though, as it doesn't matter if the client is not sent
commands if the server is restarting. Using the default async pool caused issues to arise
due to the shutdown logic generally being much later.

Subject: [PATCH] Limit Client Sign length more
modified clients can send more data from the client
to the server and it would get stored on the sign as sent.
Mojang has a limit of 384 which is much higher than reasonable.
the client can barely render around 16 characters as-is, but formatting
codes can get it to be more than 16 actual length.
Set a limit of 80 which should give an average of 16 characters 2
sets of legacy formatting codes which should be plenty for all uses.
This does not strip any existing data from the NBT as plugins
may use this for storing data out of the rendered area.
it only impacts data sent from the client.
Set -DPaper.maxSignLength=XX to change limit or -1 to disable

Subject: [PATCH] Optimize Network Manager and add advanced packet support
Adds ability for 1 packet to bundle other packets to follow it
Adds ability for a packet to delay sending more packets until a state is ready.
Removes synchronization from sending packets
Removes processing packet queue off of main thread
- for the few cases where it is allowed, order is not necessary nor
should it even be happening concurrently in first place (handshaking/login/status)
Ensures packets sent asynchronously are dispatched on main thread
This helps ensure safety for ProtocolLib as packet listeners
are commonly accessing world state. This will allow you to schedule
a packet to be sent async, but itll be dispatched sync for packet
listeners to process.
This should solve some deadlock risks
Also adds Netty Channel Flush Consolidation to reduce the amount of flushing
Also avoids spamming closed channel exception by rechecking closed state in dispatch
and then catch exceptions and close if they fire.

Subject: [PATCH] Optimize Captured TileEntity Lookup
upstream was doing a containsKey/get pattern, and always doing it at that.
that scenario is only even valid if were in the middle of a block place.
Optimize to check if the captured list even has values in it, and also to
just do a get call since the value can never be null.

Subject: [PATCH] Allow Saving of Oversized Chunks
Note 1.17 update: With 1.17, Entities are no longer stored in chunk slices, so this needs updating!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The Minecraft World Region File format has a hard cap of 1MB per chunk.
This is due to the fact that the header of the file format only allocates
a single byte for sector count, meaning a maximum of 256 sectors, at 4k per sector.
This limit can be reached fairly easily with books, resulting in the chunk being unable
to save to the world. Worse off, is that nothing printed when this occured, and silently
performed a chunk rollback on next load.
This leads to security risk with duplication and is being actively exploited.
This patch catches the too large scenario, falls back and moves any large Entity
or Tile Entity into a new compound, and this compound is saved into a different file.
On Chunk Load, we check for oversized status, and if so, we load the extra file and
merge the Entities and Tile Entities from the oversized chunk back into the level to
then be loaded as normal.
Once a chunk is returned back to normal size, the oversized flag will clear, and no
extra data file will exist.
This fix maintains compatability with all existing Anvil Region Format tools as it
does not alter the save format. They will just not know about the extra entities.
This fix also maintains compatability if someone switches server jars to one without
this fix, as the data will remain in the oversized file. Once the server returns
to a jar with this fix, the data will be restored.

Subject: [PATCH] Only count Natural Spawned mobs towards natural spawn mob
limit
This resolves the super common complaint about mobs not spawning.
This was ultimately a flaw in the vanilla count algorithim that allows
spawners and other misc mobs to count against the mob limit, which are
not bounded, and can prevent the entire world from spawning new.
I believe Bukkits changes around persistence may of actually made it
worse than vanilla.
This should fully solve all of the issues around it so that only natural
influences natural spawns.

Subject: [PATCH] Configurable projectile relative velocity
This patch adds an option "disable relative projectile velocity", which, when
enabled, will cause projectiles to ignore the shooter's current velocity,
like they did in Minecraft 1.8 and prior.
If a player is falling, for example, their shooting range will be drastically
reduced, as a downwards velocity is applied to the projectile. This prevents
players from saving themselves from falling off floating islands, for example,
as a thrown ender pearl will not make it back to the island, while it would
have in 1.8.
While this could easily be done with plugins, too, there are multiple problems:
P1) If multiple plugins cancel the velocity by subtracting the shooter's velocity
from the projectile's velocity, the projectile's velocity would be different.
As there's no way to detect whether the projectile's velocity has already been
adjusted to ignore the player's velocity, plugins can't not do it if it's not
necessary.
P2) I've noticed some inconsistencies, e.g. weird velocity when shooting while
using an elytra. Checking for those inconsistencies is possible, but not as
efficient as just not applying the velocity in the first place.
P3) Solutions for 1) and especially 2) might not be future-proof, while this
server-internal fix makes this change future-proof.

Subject: [PATCH] Duplicate UUID Resolve Option
Due to a bug in https://github.com/PaperMC/Paper/commit/2e29af3df05ec0a383f48be549d1c03200756d24
which was added all the way back in March of 2016, it was unknown (potentially not at the time)
that an entity might actually change the seed of the random object.
At some point, EntitySquid did start setting the seed. Due to this shared random, this caused
every entity to use a Random object with a predictable seed.
This has caused entities to potentially generate with the same UUID....
Over the years, servers have had entities disappear, but no sign of trouble
because CraftBukkit removed the log lines indicating that something was wrong.
We have fixed the root issue causing duplicate UUID's, however we now have chunk
files full of entities that have the same UUID as another entity!
When these chunks load, the 2nd entity will not be added to the world correctly.
If that chunk loads in a different order in the future, then it will reverse and the
missing one is now the one added to the world and not the other. This results in very
inconsistent entity behavior.
This change allows you to recover any duplicate entity by generating a new UUID for it.
This also lets you delete them instead if you don't want to risk having new entities added to
the world that you previously did not see.
But for those who are ok with leaving this inconsistent behavior, you may use WARN or NOTHING options.
It is recommended you regenerate the entities, as these were legit entities, and deserve your love.
