7d29eb5e SPIGOT-4899: Horse inventory title not set
Tux pointed out the patch still has O(n^2) time complexity since
the sublist class in arraylist does not override clear() from
AbstractList, which uses a forward moving iterator to clear
the list.
Resolved by using a peek and poll from ArrayDeque.
This patch also removes the useless WeakHashMap which holds
the list (it mapped world->list) and replaces it with a
field on World.

for Timings v2. It should be kept in that scope.
- Intend to let PlayerViewDistance API slip. Given the scope of the
changes in this area it seems best to let this slip past initial
release. It can be re-added when there is additional time to focus on it
and the changed systems it relies on. If it is fixed prior to release
this is implemented as a single shim patch that can be dropped.

CraftBukkit uses vanillas DimensionManager, but does not actually
register its own dimension types, etc, due to vanilla
This causes issues because anything, e.g. command feedback, trying
to print information about the world will often attempt to print out
the dimension name, which ends up throwing an NPE due to the lack of
a registered type, we work around this by just returning the world name,
this is not super elegant, but is the only route that promises not to
break stuff.
This fixes issues with upstreams changes to solve a private issue on
their side, as signs are placed, they may replace existing blocks, e.g.
grass, which breaks upstreams assumption that the sign is always placed
adjacent to a surface
Brought this patch back from the graveyard, 1.13.x changed how chunks
where loaded and the patch was dropped.
Prior to this change the server would crash when attempting to load a
chunk from a region with bad data.
After this change the server will defer back to vanilla behavior. At
this time, that means attempting to generate a chunk in its place
(and occasionally just not generating anything and leaving small
holes in the world (This might not be accurate as of 1.13.x)).
Should Mojang choose to alter this behavior in the future, this change
will simply defer to whatever that new behavior is.
Resolves#1672
This API is intended to expose useful heightmaps found in the server to API. This exposes all of the live world heightmaps currently in the server.
If a heightmap becomes impossible to implement, api spec allows the implementation to throw UnsupportedOperationException (far better than returning some weird unexpected value).

812f66aa SPIGOT-4684: Update persistence of converting zombie villagers
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.
We bandaided this logic on a case by case basis before with Loot Tables and Chests,
but that is not the correct fix.
Ultimately we just needed to clear out the captured tile entity list so that the
update calls did not process the tile entity that is no longer even valid.
This solution will ensure ALL placed tile entities data is ignored and not just
the few cases we previously had filters for.
The cost of a call to sync() adds up quickly and especially for
HDDs. Playing around generating chunks for a while warranted a
3 min save time on a HDD. This is unacceptable default behaviour
and now the behaviour is hidden behind a flag for server owners
who are OK with taking a hit on saves (although SSDs will not have
this issue remotely as bad, since most of the time was spent seeking).
It is possible for a container to be brought into the world pre-filled
in place event (thanks NBT!). When the blockplacevent(s) are cancelled
their blockstate is updated in OBC. This triggers them to drop their
inventories.
Rather than screwing with the update method which is used elsewhere, we
can simply clear any inventories once we are told that a plugin intends
to cancel the interaction.
Fixes GH-1831
While it wasn't really "broken" before, if plugins use NMS
(which they really should't be) and mess with entity management
themselves, and get it wrong, they could ultimately corrupt our
state expectations.
I've been unable to reproduce any issues locally, but these changes
are the result of me analyzing the code pretty deeply and seeing
about how to make it more durable to abnormal usage.
Any servers seeing oddities, please run with -Ddebug.entities=true
and send me any logs triggered.
Why are plugins accessing this?! Whhhhy?!
For any plugin developers reading this, this are methods in World
specifically for adding entities to the world, aptly called spawnEntity
Previously we would write to header before writing our chunk data,
which opens a window for corruption (or we would overwrite entirely).
Now the saving process has been changed to follow this chain of events:
1. We always allocate a new space to write so we do not potentially
overwrite and corrupt the current data
2. Write the chunk data first (the order of the fields in
the chunk data isn't relevant though)
3. Flush to disk
4. Write to the region header last
5. Flush to disk
6. Then we free the previous space allocated
With this chain of events it is impossible for a chunk write to corrupt
a region file, unless the operating system has lied and we have NOT flushed
to disk.
However server administrators are still recommended to continue performing
regular backups.
Note that when Mojang finally decides to change their region format
to deal with oversized chunks this patch must be changed to deal with
whatever system they decide to impose.
We also make use of two flushes to disk per chunk save (to ensure
ordering and ensure data has gone to disk), so this will negatively
affect save performance.

Plugins that rely on the async login event to fire can miss the event
if a player tries to log in before the server has loaded.
The solution is to simply block the event threads from executing until
the server has loaded. This will not have an adverse affect on logins
since the event threads are cached and are only used for executing events
asynchronously.
We pretty much reverted most of Spigots changes here as ours is better.

This is caused due to the DimensionManager in CB worlds not being
registered by NMS, we fix this by copying CBs behavior of using the
world providers DimensionManager, vs using the actual dimension manager
of the world
Now decounts entities that got name tagged or persistent state changed.
Removes a bad CB check that ignored some persistent mobs persistence state.
Vanilla code explicitly only cares 'is this mob persistent?' and if
it is, it is not counted. CB should not of been checking its type state.
Fixes#1922
removes Mineshaft loading legacy as we had pre 1.13.2 to avoid managing
that very large data file from legacy systems.
Previous to 1.13.2 these data files were never loaded to begin with, so they
effectively do not contain valid/relevant data.
These files take a long time to convert on large worlds and crashes the server.
Additionally, cache the result of a file being missing so we don't keep spam checking it.
This code could get hit by many threads at once, causing multiple
chunk loads to convert legacy data, leading to all sorts of fun.
Additionally, go ahead and preload it async on world load.
Instead of allocating a buffer for every chunk compression, reuse
the same 64k sized buffer.
Also stopped doing dynamic compression levels. It wasn't helping enough.
This will improve memory usage and zlib performance of chunk compression.
Exposes a mutable array on items a player should keep on death.
This allows a cleaner method to implement "Keep certain items on death"
than how plugins currently do it in that it never removes them in first
place, so its safe if the player logs out/server is shutdown before respawn.

PlayerList#moveToWorld already untracks the player from the player list,
meaning that we do not need to worry about this untracking players
who've left the world, The server also untracks a player during
disconnect, handing yet another case.
If we don't need to untrack players who've left the world, it should be
reasonably save to do this, as we're not going to be performing any
server->client updates here, which is what this code is intended to do,
and all players should be untracked.
turning this to true allows 1 player to deny other players the ability
to have mobs spawn. It really is a bad idea and reverts back to iffy
mob spawn limits where mob farms in the world stops natural spawns
from occuring.
Really recommend resorting to different solutions than ever using this config.

51100db8 SPIGOT-4678: Fix placing signs in certain circumstances
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.
Allows you to return the SpawnReason for why an Entity Spawned
Pre existing entities will return NATURAL if it was a non
persistenting Living Entity, SPAWNER for spawners,
or DEFAULT since data was not stored.

Prior to this change, the lastTick value for zombies would be set to
their initial spawn tick. This caused the drowned conversion process to
immediately occur rather than observing the vanilla delay.
Easy fix, just make sure its set again when the process actually starts.
And no, this change has absolutely nothing to do with the other thing.
That's been fixed and remains fixed.
Mojang stored whitelist state in 2 places (Whitelist Object, PlayerList)
some things checked PlayerList, some checked object. This moves

Also adds a limit to stop sending Sign data to client after 500
signs per chunk to limit client lag.
Use -DPaper.excessiveSignsLimit=500 to configure that limit, or -1
to disable the limit and let your players be abused.
fixes#1878
now 80 chars counts multi sized code points the same so 80 chinese
characters would be allowed too.
Removed outbound limit as it doesn't solve the chunk oversize problem.
proper fix for chunk sending in another patch next.
we missed something in updating this patch and accidently left
hashCode as a 0 value. This caused a pretty nasty performance hit
for BlockStateEnum instances as they would be all a hash collision.
This update fixes that and also promotes the optimizations to cover
ALL cases of Block States, not just enums.
While mojang cached hashCode in 1.13, we can still just use a simple
large prime based hashCode that auto increments guaranteeing no overlap.
Additionally, replace all equals with an identity check.
modified clients can send abnormally large data from the client
to the server and it would get stored on the sign as sent.
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 to and from the client.
Set -DPaper.maxSignLength=XX to change limit or -1 to disable
per feedback from @liach about a bug with vanillas previous logic
that we essentially just reverted to. complex recipes could run into
cases where a recipe that does have enough items can be unsatisfied
if the items are in certain orders, making them not truely shapeless.
this scenario doesn't occur in vanilla, but users can load custom recipes.
this improves the logic to do some sorting on the lists to improve
chances of matching the recipes harder ingredients before the easier
to satisfy ingredients.
the likelyhood of someone adding a recipe that still fails this is too
extreme to care about. i doubt mojangs implementation is perfect either.
we can improve this logic more later if we actually get bug reports on it.
Mojang implemented Shapeless different than Shaped
This made the Bukkit RecipeChoice API not work for Shapeless.
This reimplements vanilla logic using the same test logic as Shaped
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, as this will not fire
with the same velocity as BPE.
Also fixes build as a result of an upstream force push

Please test this build on a local TEST SERVER before sending to your live server!
PaperMC is not responsible for any data loss to your chunks.
-------------------------------------------------------------------
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.
If anything throwable is thrown, be sure its caught too.
Because I totally did new Error() out of javascript habit...
This ensures that chunk loading process cant get stuck due to uncaught errors
