10d58504f7 don't NPE on dimensionmanager toString
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.

41c86a6548 Handle bad chunks more gracefully
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.

237250c08d Add Heightmap API (#1724)
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).

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.

Improve Cancelled Block Place Tile Entity discardment
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.

6d7b032d2b Only flush to disk on chunk saves if paper.flush-on-save is true (#1942)
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).

Clear containers on cancelled place events
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.

Numerous fixes to entity related changes
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.

Make region files more reliable to write to
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.

Allow login events to fire only after the server has loaded
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.

Optimize Persistent Data Loading
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.

PlayerDeathEvent#getItemsToKeep
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.

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.

Set Zombie lastTick at start of drowned conversion
Fixes GH-1887

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.

MC-145260: Fix Whitelist On/Off inconsistency - Fixes #1880
Mojang stored whitelist state in 2 places (Whitelist Object, PlayerList)

some things checked PlayerList, some checked object. This moves
everything to the Whitelist object.

Handle Excessive Signs in Chunks creating too large of packets
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

Remove outbound string length limits on signs, improve codepoint logic
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.

Fix BlockState hashCode optimization patch performance bug
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.

Strip extra Sign data to/from client - Fixes #1876
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

Improve reliability of Shapeless Recipe logic
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.

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, as this will not fire
with the same velocity as BPE.
