This event extends the PreCreatureSpawnEvent and includes the position
of the spawner that spawned the entitiy. (similarly to how the
SpawnerSpawnEvent contains the spawner's BlockState).
This one doesn't include the state though as getting the block and
generating that snapshot is a bit wasteful.
Modifying of permissions was only half protected, enabling concurrency
issues to occur if permissions were modified async.
While no plugin really should be doing that, modifying operations
are not heavily called, so they are safe to add synchronization to.
Now, all modification API's will be synchronized ensuring safety.
Additionally, hasPermission was victim to a common java newbie mistake
of calling if (containsKey(k)) return get(k), resulting in 2 map lookups.
Optimized it to simply be a single get call cutting permission map
lookups in half.
Adds an API to allow plugins to instruct a Mob to Pathfind to a Location or Entity
This does not do anything to stop other AI rules from changing the location, so
it is still up to the plugin to control that or override after another goal changed
the location.
Adds an API to allow plugins to instruct a Mob to Pathfind to a Location or Entity
This does not do anything to stop other AI rules from changing the location, so
it is still up to the plugin to control that or override after another goal changed

The PluginManager incorrectly used synchronization on firing any event
that was marked as synchronous.
This synchronized did not even protect any concurrency risk as
handlers were already thread safe in terms of mutations during event
dispatch.
The way it was used, has commonly led to deadlocks on the server,
which results in a hard crash.
This change removes the synchronize and adds some protection around enable/disable
This method will return the Block a player is looking at while taking into consideration the AABB of each block in the path.
For example, you can look through the 1/4 space of air in a Stair block and get the block behind it instead of the Stair block you are looking past.

With 1.13, the idea of accessing chunks async is going to have to
be supported with the push towards thread safe chunk access mojang
has done.
This commit changes timings to always thread check at start and stop
timings and only mutate state on main thread.
This makes startTimingIfSync pointless, but I'm just going to leave
it as is.
Timings will no longer complain when used async, it just will not
do anything.
Further concurrency issues have been addressed with creating
timings handlers that may of overall been an issue for any handler
that might of been created async (happened even for things that
only timed sync)
with that, the 'protected' concept of handlers has been removed,
and 'plugin' vs 'safe' handlers are now the same.
Got rid of some guava functions in favor of java 8 real stuff now too.

Adds new slime pathfinder related events. All events can be cancelled.
- `SlimePathfindEvent` is the base event of all added events. Cancelling this event will cancel all pathfinders.
- `SlimeWanderEvent` is called when slimes wander around by either swimming or moving/jumping forward. Cancelling this event will prevent slimes from moving around and jumping, but they will still look around and target players.
- `SlimeSwimEvent`is called when slimes are swimming in water/lava. Cancelling will prevent the slimes from moving/jumping in water/lava.
- `SlimeChangeDirectionEvent` is called when a slime changes directions. It contains the new `yaw` position the slime wants to change to, and it can be set to another value. Cancelling this event will prevent slimes from changing directions (except for when targeting players).
- `SlimeTargetLivingEntityEvent` is called when a slime targets a player. NMS uses EntityLiving here so it is named this. Contains the LivingEntity the slime has targeted. Cancelling this event will prevent the slime from targeting the entity and will make it lose current focus.
Adds `Slime#canWander()` and `Slime#setWander(boolean)` for a more persistent control (does not persist server restarts) over all 4 pathfinder types without the spammy event having to be cancelled a bajillion times a second.

Related changes in this commit;
- Add a force option to the ParticleBuilder API, which defaults to true to keep spigot consistent with existing api.
- Add a new spawnParticle method to support this mode as a parameter. Of course kept existing api methods the same so as to not break them.

Put the decompile fixes into MC Dev Fixes patch
Optimize RegistryID.c()
This branch/commit is only useful to those who purely use a clean Bukkit/Spigot/Paper API
and does not use NMS/OBC references.
This will let you start updating your plugin to the latest 1.13 builds of Bukkit Preview (4 as of now)
Note that this release is not final!!! API breakages may occur!
It is up to you if you find use out of this work.
This enables us a fast reference to the entities current chunk instead
of having to look it up by hashmap lookups.
We also store counts by type to further enable other performance optimizations in later patches.
This is the best way to get an entity when the world and its UUID are known.
It is faster than Server.getEntity(UUID) because it does not have to iterate all worlds
This fixes a CRITICAL missing part of the Bukkit API due to mistakes on upstream
refusing to implement the Sentient NPC baseclass of all NPC's.
Until now, the Bukkit API has not provided a way for accessing and setting
a non creature entities target.
Although Flying, Slime, Ambient, and Water mobs all supported targets internally,
you were unable to get/set it.
Now with the SentientNPC API and these API's moved down, every sentient NPC has
access to target data.
This event is called when an entity receives knockback by another entity. The knockback can be modified in the event. If the event is cancelled the entity is not knocked back.
Called when a player is firing a bow and the server is choosing an arrow to use.
Plugins can skip selection of certain arrows and control which is used.
Used to determine ACTUAL Living NPC's. Spigot mistakenly inversed the conditions for LivingEntity, and
used LivingEntity for Insentient Entities, and named the actual EntityLiving class EntityInsentient.
This should of all been inversed on the implementation side. To make matters worse, Spigot never
exposed the differentiator that there are entities with AI that are not sentient/alive such as
Armor stands and Players are the only things that do not implement the REAL EntityLiving class (named Insentient internally)
This interface lets you identify NPC entities capable of sentience, and able to move about and react to the world.
Redirects are in place (or will be shortly). This is mostly
housekeeping.
Maven repo URLs already redirect however we can't deploy through them.
Jenkins URLs do not currently redirect but will within 24 hours.
Also adds a Discord link to the README, because apparently that's what
people want.
Documentation will be updated and announcements made once all redirects
are in place, until then, consider this advanced notice.
Adds ability to control who receives it and who is the source/sender (vanish API)
the standard API is to send the packet to everyone in the world, which is ineffecient.
This adds a new Builder API which is much friendlier to use.
Fires an event anytime an enderman intends to teleport away from the player
You may cancel this, enabling ranged attacks to damage the enderman for example.
Resolves#1101
It is often difficult to diagnose new issues server admins get when
upgrading to a new server version because the only information they are
able to tell us regarding the server version they are running is
"latest". This commit attempts to mitigate this by keeping track of the
previous version of Paper they were running, which is then reported by
the `/version` or `/paper version` command. This gives us a better idea
of the commits included in the upgrade, which may help diagnose new
issues easier.
It was using a redirect, but apparently a small portion of systems,
networks, some mess, are having problems with that redirect.
Just use the direct link and skip the hassle.
In some enviroments, the channel limit set by spigot can cause issues,
e.g. servers which allow and support the usage of mod packs.
provide an optional flag to disable this check, at your own risk.
* Make the legacy ping handler more reliable
The Minecraft server often fails to respond to old ("legacy") pings
from old Minecraft versions using the protocol used before the switch
to Netty in Minecraft 1.7.
Due to packet fragmentation[1], we might not have all needed bytes
available when the LegacyPingHandler is called. In this case, it will
run into an error, remove the handler and continue using the modern
protocol.
This is unlikely to happen for the first two revisions of the legacy
ping protocol (used in Minecraft 1.5.x and older) since the request
consists of only one or two bytes, but happens frequently for the
last/third revision introduced in Minecraft 1.6.
It has much larger, variable packet sizes due to the inclusion of
the virtual host (the hostname/port used to connect to the server).
The solution[2] is simple: If we find more than two matching bytes,
we buffer the remaining bytes until we have enough to fully read and
respond to the request.

* Add legacy ping support to PaperServerListPingEvent
Add a new method to StatusClient check if the client is a legacy
client that does not support all of the features provided in the
event.
Some plugins (e.g. older builds of EssentialsX) assume that
ServerListPingEvent.getSampleText() returns a mutable copy of
the player sample list. This was the case until it was refactored
on top of the new API introduced in #980.
As a result, they may run into an error when trying to modify the
returned list directly. Modify getSampleText() to return a mutable
copy (a plain ArrayList) to mimic the old behavior.
Don't want to risk mutating players properties in server list (unlikely, but lets be proper)
and Skull also has a setter API, so that should be used too.
* Drop original implementation for old player sample API
* Add extended PaperServerListPingEvent
Add a new event that extends the original ServerListPingEvent
and allows full control of the response sent to the client.
* Implement deprecated player sample API
I mistakenly thought .complete() also checked for textures, which was not the case
So the logic was not working as desired.
Also some undesired logic paths lead to textures of the logging in player being dropped, forcing
us to always load the textures immediately again on login, leading to rate limits.
Everythings now good
the .complete() api now will default specify to also complete textures, but you may
pass false to it to skip loading textures.
Gets the unique ID of the player currently known as the specified player name
In Offline Mode, will return an Offline UUID
This is a more performant way to obtain a UUID for a name than loading an OfflinePlayer
This is faster if all you need is the UUID, as .getOwner() will cause
an OfflinePlayer to be loaded from disk.
This method is already implemented on the server, just needed to expose it.
- Lots of itemstack cloning removed. Only clone if the item is actually moved
- Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items.
However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on.
- Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory
- Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration
This is adds basic item meta for armor stands. It does not add all
possible metadata however.
There are armor, hand, and equipment types, as well as position data
that can also be added here. This initial implementation should serve as
a starting point for future additions in this area.
Fixes GH-559
Allows plugins to populate profile properties from local sources to avoid calls out to Mojang API
to fill in textures for example.
If Mojang API does need to be hit, event fire so you can get the results.
This is useful for implementing a ProfileCache for Player Skulls
This simply provides the base API to create the objects. Further commits will come that adds
adds usage of this API to existing GameProfile based API's, as well as new API's.
This event can be used for when you want to exclude a certain player
from triggering monster spawns on a server.
Also a highly more effecient way to blanket block spawns in a world
Adds an event to fire before an Entity is created, so that plugins that need to cancel
CreatureSpawnEvent can do so from this event instead.
Cancelling CreatureSpawnEvent rapidly causes a lot of garbage collection and CPU waste
as it's done after the Entity object has been fully created.
Mob Limiting plugins and blanket "ban this type of monster" plugins should use this event
instead and save a lot of server resources.
See: https://github.com/PaperMC/Paper/issues/917
This allows plugins that give players the ability to apply the experience
points to the Item Mending formula, which will repair an item instead
of giving the player experience points.
Both an API To standalone mend, and apply mending logic to .giveExp has been added.
Fired when the server is about to merge 2 experience orbs
Plugins can cancel this if they want to ensure experience orbs do not lose important
metadata such as spawn reason, or conditionally move data from source to target.
Any plugin still using this API will result in the server saving an inconsistent UUID to player data files,
which then triggers warnings such as "Tried to load unrecognized recipe: bukkit:9e5b92f5-e549-4f47-b0a8-9f89390ed77b removed now."
on the players login.
Plugin authors need to define a key to keep it consistent between server restarts.
Let plugins be able to control tab completion of commands and chat async.
This will be useful for frameworks like ACF so we can define async safe completion handlers,
and avoid going to main for tab completions.
Especially useful if you need to query a database in order to obtain the results for tab
completion, such as offline players.
Also adds isCommand and getLocation to the sync TabCompleteEvent
Essentials uses a custom logger name ("Essentials") instead of the
plugin logger. Log messages are redirected to the plugin logger by
setting the parent of the "Essentials" logger to the plugin logger.
With our changes, the plugin logger is now also called "Essentials",
resulting in an infinite loop. Make sure plugins can't change the
parent of the plugin logger to avoid this.
SLF4J is a commonly used abstraction for various logging frameworks
such as java.util.logging (JUL) or Log4j. Currently, plugins are
required to do all their logging using the provided JUL logger.
This is annoying for plugins that target multiple platforms or when
using libraries that log messages using SLF4J.
Expose SLF4J as optional logging API for plugins, so they can use
it without having to shade it in the plugin and going through
several layers of logging abstraction.
the first 'major' change in this PR is to cache the generated event
executrs from the ASM class, by doing this we only generate a single
class for every method that we need an executor for, thus reducing the
number of classes that are needed, especially in cases where plugins
re/unregister events all the time.
The second change is to modify the generated classloader map, generated
classloaders are not held against the plugin itself but the classloader
that the event is declared in, the implication here is that we cannot
drop generated classloaders when a plugin disable, and so we use a guava
weak-key'd hashmap, downfall here is that classes won't be GC'd until
guava drops the generated classloader, however the first change should
deal with most of the grunt.
Gets the Display name as seen in the Client.
Currently the server only supports the English language. To override this,
You must replace the language file embedded in the server jar.
This will take a Bukkit ItemStack and run it through any conversions a server process would perform on it,
to ensure it meets latest minecraft expectations.
Not all horses with Saddles have armor. This lets us break up the horses with saddles
and access their saddle state separately from an interface shared with Armor.
Adds a Pre Lookup Event and a Post Lookup Event so that plugins may prefill in profile data, and cache the responses from
profiles that had to be looked up.
Fixes our own, and upstream's, issues with the stricter Java 8 JavaDoc
linter.
Also removes the destroystokyo-release maven repository. I'm not sure
why I added it originally, but it's unnecessary now.
Spigot has patched this issue inside MapIcon, meaning that we no longer need to maintain this patch; Spigots patch also fixes#668 in that it will verify the length of the array, as well as protect against a negative type value being fetched from the array. Only real change is that Spigots patch returns a MapIcon.Type.PLAYER, instead of the RED_MARKER as originally PR'd by Aikar.
Also add "commands" to Tab Completion
Note: This required a signature change to Bukkit#reloadCommandAliases() so that it returns a boolean based on if the command aliases reloaded or not.
Finally made timings accept "Callback style" reports, so plugins
can listen for when the report is done.
Added new Util interfaces, MessageCommandSender and BufferedCommandSender
This restores and improves using RCON to generate timings reports
I believe we are getting data corruption by doing it in the middle of the tick, as I was seeing
really odd reports from automated ones vs command ones.
This will break issueing timings over rcon single command mode and getting the report link in the response back
But I will try to restore that (and make RCON no longer cause spikes) soon.
Reports will still generate, just because its async, the RCON connection
will drop if not in terminal mode before its done.
The Component based methods are not even safe to use, as it may result in invalid items being sent to the client.
The string based method we have added is the only safe way to send with the API.
The client is stricter about componenents being sent for this API, and does not accept children components.
The client is expecting a legacy string.
Require user to confirm the timings reset, warning them that they should not be doing this.
Also require Timings to have ran for 3 minutes before allowing the report command.
Also require 1 minute intervals between reports to stop report spam.
Provides an API to control the loot table for an object.
Also provides a feature that any Lootable Inventory (Chests in Structures)
can automatically replenish after a given time.
This feature is good for long term worlds so that newer players
do not suffer with "Every chest has been looted"
API and Event added to control the Auto Replenish feature for players.
Allowing only non-zero BlockIterators breaks an API contract explicitly allowing them
(*eyeroll*)
And loading chunks earlier in the TP patch did not resolve the original issue, and now
that it is resolved, shouldn't actually provide any tangible benefits
This will drastically reduce file size on large servers and help
avoid the parser failing to load the report.
This will also reduce memory usage of timings data.
Importing the full library would double the jar size... its way too large.
So lets just import the basic int/long based collections to then use
to improve performance on these kind of collections.
Use ConcurrentHashMap to allow thread-safe access methods and very
limited synchronized portions to allow much higher concurrency in
MetadataStore as well as far less locking, especially on reads
Fires when an Entity decides to start moving to a location.
This is not the same as a move event. This only fires when an entity chooses
to start moving to a location, and allows cancelling that pathfind.
Additionally, only get is supported for now. Unsure if changing target location
is safe to do.
These events will give plugins a reliable way to track every entity that is added
or removed from a world, so that one may always ensure they are in a desired state.
Reflection (although highly optimized), has noticable overhead.
It also creates noticable GC overhead by allocating arrays with arguments, as @Aikar has said.
