CraftBukkit Changes:
e7ced970 Catch plugins setting null Material or BlockData to blocks
fixes an issue in which thread requests are only processed
for the current provider which can cause a deadlock should
multiple requests exist across providers
These methods are used internally throughout the game for things like spawning mobs during day/night only or making them burn in daylight, etc. Now exposed for plugin usage.
we've seen some index lines change in length in some PR's, though
this script was suppose to ignore those changes already.
The only way I can see that not working is if the color mode
of grep is breaking the pattern matching, as some people
default their grep to use color=always
this adds color=none to ensure colors are disabled, should ensure it.
If a chunk load comes in on a chunk load or gen thread,
execute it synchronously on that thread instead of enqueueing it.
It doesn't make sense to enqueue it as that thread is then
going to future.join() it and block until it's ready anyways.
This opens risk to a deadlock if every load or gen thread is
waiting on a recursive chunk but it will never finish because
all of the threads are waiting.
If we identify an invalid offset (negative, or the header sectors),
then back up the region file and erase that specific chunks offset
data.
This will avoid crashing the server with AIOBB errors and also avoids
server owners having to consider the entire region file 'lost'.
I'm not sure what leads to this state, I can only assume write cut
off mid bits.
In this scenario, there is absolutely no way to know where the chunk
actually is in the data file without loading every
single chunk in the file. And even to do that, would be quite extreme
due to the fact the file isn't in some orderly fashion.
Since the file is backed up, the user can use a region fixer tool
externally to try to restore that single chunk. We could even
add a command to restore a chunk from a backup file in a different
commit later on. But this at least prevents the server from crashing.
The server will just generate a new chunk and move on,
after printing an error to the console about it.
Also fixed the case reported in this issue about the server
hanging when a corrupt chunk is encountered, so this issue
is now fully closed.
Resolves#1541
Applied a "Only run this when the blocks are different" to
a place, that apparently must be called even with the same
block but different other data I guess.
This was causing oddness with light data.
Chunk Generation was occuring while inside of the progressCache lock
this caused the progressCache to stay blocked for a long period of time
which then blocked main when main needed to clean the expiring map.
We now maintain a separate map for pending scheduler entries, that
we can join on if a 2nd request comes in while one is starting.
This strategy keeps the lock only for a fraction of time but
maintains thread safety.
So now the chunk is generated without holding a lock and wont
block the main thread on the expiring map as we will insert it
once ready.
1) Removed "Regen" mode of Dupe UUID resolver, forced safe.
Some servers who updated before we had safe mode added still had this value.
There's really no reason to keep this mode, as we've seen that vanilla
triggers this often and 99.9999999% of cases will be an actual duplicate
that needs to be deleted.
2) Made Vanilla Debug messages about dupe UUIDs and dupe uuid resolve messages
only show up if the debug.entities flag is on. This will stop server owners
from panicing from seeing these logs, and stop opening bug reports on this,
only for us to tell you "don't worry about it".
3) Avoid adding entities to world that are already added to world.
This can be triggered by anything that causes an entity to be added
to the world during the chunk load process, such as chunk conversions.
Issue #1544 was a case of this.
4) Removed debug warning about ExpiringMap.
Nothing more I know to do about this anyways. We recover from it,
stop warning to reduce noise of issues to us.
Seems my original pull for this created an unseen bug where the target timer would never run out (the slime would not "forget" it's target over time). Went ahead and fixed that, and made the code more legible by adding the imports.
This adds a plethora of useful Tags to let you identify common grouping
of materials. This should complete all of the categories that mojang
did not provide official tags for plus some more.
These are not "registered" tags. They are not usable in any form of
command system that might support tags.
These are provided as a Paper maintained list of items so that plugins
do not have to worry about maintaining all these tags themselves.
This API can technically be copy and pasted into a plugin, and plugins
can add additional Tags's if they wish too to their plugin by
instantiating a MaterialSetTag.

This will improve queue times by canceling chunks when a player
leaves the radius of an async loading/generating chunk.
This matches behavior we had pre 1.13 for loading too.

Primarily to update plugins for our fastutil relocation. Can also be
used to do things like debug plugins accessing versioned NMS packages in
an IDE pre-relocate step.
Following this comment on PaperLib, https://github.com/PaperMC/PaperLib/pull/2#discussion_r222761017
I've made non-snapshot TE's not update when they receive the update call. They still do the rest of the update, just not the applying of the TE data. This is to still allow forced physics updates etc. Also in the case of Jukeboxes, updating the properties
improved the water code so that immunity wont trigger if the entity
has the water pathfinder system active, so this improves support
for all entities that know how to behave in water.
Merged 2 EAR patches together, and removed an MCUtil method that
doesnt have a purpose anymore
Anything that posts something to main thread was not
correctly reporting their errors to the logger, passing the
ExecutionExcetion instead of the cause. This resolves that,
as well as patches some simple cases of System.nanoTime where mojang
had used a LongSupplier to use a different method on client.
This update introduces Entity Activation Range for water mobs.
Activation Range has been one of my biggest performance improvements
I ever added to Minecraft, however "Entity is in Water" is an immunity
case that keeps an entity active.
This update ignores the water check for known water based mobs, allowing
them to actually go inactive.
In addition to that, a new config option was added to spigot.yml to go with
the rest of the entity-activation-range options to let you configure
aquatic mobs like fish, squid and dolphins separately.
This should overall fix all lag caused by water mobs.
These deps were marked as provided, not compile, so they were never
exposed to plugins anyways as we THOUGHT we had done, oops.
Well plugins can still add fastutil to their build and use the
deps as provided by minecraft.
This ensures -api side does not use a deprecated API as fastutil 8
removed the deprecated methods.

FileIOThread was using two volatile counters in order to track if
any pending work was in the queue, this causes potential concurrency
issues when this counter is updated from multiple threads, potentially
causing these counters to desync due to the unsafe volatile update
