This patch detects whether or not the server is currently executing as a privileged user and spits out a warning.
The warning serves as a sort-of PSA for newer server admins who don't understand the risks of running as root.
We've seen plenty of bad/malicious plugins hit markets, and there's been a few close-calls with exploits in the past.
Hopefully this helps mitigate some potential damage to servers, even if it is just a warning.

Sometimes, blocks are changed and then logic is called before the associated
tile entity is removed. When this happens, the factories were relying on the
block at the position, not the tile entity. This change prioritizes using the
tile entity type to determine the block state factory and falls back on
the material type of the block at that location.

Prior to this commit, the tropical fish bucket meta would set the body
color to the previous metas pattern colour when updating the pattern
colour.
This commit hence simply fixes this by using the proper body colour
value when updating the pattern color.
Add commands to get the mobcaps for a world, as well as the mobcaps for
each player when per-player mob spawning is enabled.
Also has a hover text on each mob category listing what entity types are
in said category
Log when the async catcher is tripped
The chunk system can swallow the exception given it's all
built with completablefuture, so ensure it is at least printed.
Add/move several async catchers
Async catch modifications to critical entity state
These used to be here from Spigot, but were dropped with 1.17.
Now in 1.17, this state is _even more_ critical than it was before,
so these must exist to catch stupid plugins.

RegistryAccess is independant from CraftServer and
doesn't require one to be created allowing the
org.bukkit.Registry class to be loaded earlier.

public net.minecraft.server.RegistryLayer STATIC_ACCESS
Faster version for isSolid() that utilizes NMS's state for isSolid instead of the slower
process to do this in the Bukkit API
Adds API for buildable, replaceable, burnable too.
When new advancements are added via the UnsafeValues#loadAdvancement
API, it triggers a full datapack reload when this is not necessary. The
advancement is already loaded directly into the advancement registry,
and the point of saving the advancement to the Bukkit datapack seems to
be for persistence. By removing the call to reload datapacks when an
advancement is loaded, the client no longer completely freezes up when
adding a new advancement.
To ensure the client still receives the updated advancement data, we
manually reload the advancement data for all players, which
normally takes place as a part of the datapack reloading.
On servers with plugins that constantly churn through scoreboards, there is a risk of
degraded GC performance due to the number of scoreboards held on by weak references.
Most plugins don't even need the (vanilla) functionality that requires all plugin
scoreboards to be tracked by the server. Instead, only track scoreboards when an
objective is added with a non-dummy criteria.
This is a breaking change, however the change is a much more sensible default. In case
this breaks your workflow you can always force all scoreboards to be tracked with
settings.track-plugin-scoreboards in paper.yml.

The existing regex is too open and allows for the absence of any actual
number data, detecting an NBT entry of just the letter "i" in upper or
lower case. This causes a single-character NBT entry to be processed as
an integer ending in "i", passing an empty String to to Integer.parseInt,
triggering an exception in loading the item.
This commit forces numbers to be present prior to the ending "i"
letter.
Fixes per world difficulty with /difficulty command and also
makes it so that the server keeps the last difficulty used instead
of restoring the server.properties every single load.
Server.reload() had this logic to give time for tasks to shutdown,
however shutdown did not...
Adds a 5 second grace period for any async tasks to finish and warns
if any are still running after that delay just as reload does.
Adds a new method to fetch the location of a player's bed without generating any sync loads.
getPotentialBedLocation - Gets the last known location of a player's bed. This does not preform any check if the bed is still valid and does not load any chunks.
Adds an option for maximum exp value when merging orbs
Adds ExperienceOrbMergeEvent
Fired when the server is about to merge 2 experience orbs
as entities. Plugins can cancel it if they want to ensure experience orbs do not lose important
metadata such as spawn reason, or conditionally move data from source to target.
Fixes an issue where the stacked count was not taking into account
for mending repairs and when merging with spigot's merge-on-spawn
logic

This is potentially a source of lots of native memory usage.
We are clearly seeing native usage upwards to 1-4GB which doesn't make sense.
Region File usage fixed in previous patch should of tecnically only been somewhat
temporary until GC finally gets it some time later, but between all the various
plugins doing IO on various threads, this hidden detail of the JDK could be
keeping long lived large direct buffers in cache.
Set system properly at server startup if not set already to help protect from this.
This notably fixes the newest "Donkey Dupe", but also fixes a lot
of dupe bugs in general around nether portals and entity world transfer
We also fix item duplication generically by anytime we clone an item
to drop it on the ground, destroy the source item.
This avoid an itemstack ever existing twice in the world state pre
clean up stage.
So even if something NEW comes up, it would be impossible to drop the
same item twice because the source was destroyed.
This patch adds a tool to find calls to getChunkAt which would load
chunks, however it must be enabled by setting the startup flag
-Dpaper.debug-sync-loads=true
- To get a debug log for sync loads, the command is
/paper syncloadinfo
- To clear clear the currently stored sync load info, use
/paper syncloadinfo clear

Adds AsyncPlayerSendCommandsEvent
- Allows modifying on a per command basis what command data they see.
Adds CommandRegisteredEvent
- Allows manipulating the CommandNode to add more children/metadata for the client
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.
