GH-1507
The canWander property is initialized to true by default, however when
loaded from NBT, if the key doesn't exist the property will be set to
false. The correct solution is to ensure the key exists before setting
the property.
The patch was previously applied wrong, and still caused chunk loads.
Now, we will prevent it again, but also added a config option to
disable this optimization.
However, I also updated it so that doors are not removed if the chunk
the door is in is unloaded, so this should avoid breaking farms.
Fixes#1506
Vanilla has some screwy logic that doesn't send a chunk until
it has been post processed. This is an issue as post processing
doesn't occur until all neighbor chunks have been loaded.
This can reduce view distance while generating terrain, but also
cause bugs where chunks are never sent to the client.
This fix always sends chunks to the client, and simply updates
the client anytime post processing is triggered with the new chunk data.
The server does a "Did my update succeed" check after setting
a blocks data to a chunk.
However, writes can not fail outside of a hard error or a
a race condition from multiple threads writing, which is
not something that should ever occur on the server.
So this check is pointless, as if it did occur, the server would
be having data corruption issues anyways.
This provides a small boost to all setType calls.
Vanilla has risk of losing entities by causing them to be
removed from all chunks if they try to move into an unloaded chunk.
This pretty much means high chance this entity will be lost in this scenario.
There is another case that adding an entity to the world can fail if
the chunk isn't loaded.
Lots of the server is designed around addEntity never expecting to fail for these reasons,
nor is it really logical.
This change ensures the chunks are always loaded when entities are
added to the world, or a valid entity moves between chunks.
Hopefully will fix issues #1496 and #1434
The server triggers light recalculations even if the new block
is the same as the old block. At this time, BlockData Properties
do not impact light calculations.
So the only way light should change, is if the block itself
changes from 1 block to another.
Additionally, as of 1.13, water now only blocks 1 light level
instead of 3, meaning that light level decreasing is the same as air.
This means, transitions between water and air also do not need
to recalculate light, which saves a TON of updates caused by
fluids flowing.

Minecraft is trying to set Dimension Objects based on a Dimension ID
Dimension ID's for custom worlds are dynamically allocate dand not guaranteed
consistent.
This removes checking the NBT data, as the Entity will always have its
DimensionManager set to the world it is being placed into.
This fixes corrupt entities breaking chunk saving in custom worlds.

This restores Asynchronous Chunk Loading to 1.13, as well as adds Asynchronous Chunk Generation..
This provides a massive boost to server performance and should bring 1.13 back closer to 1.12 performance levels for pre generated worlds.
World Generation will now be faster overall than 1.12 since 1.12 did not have async generation.
**DONATE:**
Lots of effort has went into making this happen. Want to say thanks and donate?

light queue is actually buggy, so re-enabling the config.
however, if anyone is ok with the buggy behavior, made the max time lost due to
light queue configurable.
We want to get to making the ligth queue default if we can make it work perfectly.
also applying neighbor optimizations to use the faster method for light checks.
getDimensionId() returns the dimension id - 1. So without this patch
we would reuse an existing dimension id, if some other dimension was
unloaded before.
In Spigot this is nearly invisible because DimensionManager has no equals(),
so dimension id collisions just create 2 worlds with the same dimension.
The PaperWorldMap (Added in
https://github.com/PaperMC/Paper/blob/master/Spigot-Server-Patches/0376-Optimize-Server-World-Map.patch ) changes this - Now the dimension is overwritten if there is some collision,
what causes players to teleport to incorrect worlds, World checks will no longer work
and many more evil things.

JEP 181 brings a new bytecode format for nest mates. ASM API 7 supports
this, but API 7 is still experimental. Attempting to load a Java 11
class that contains nest mates will cause an
UnsupportedOperationException, as API 6 can't handle them. This doesn't
really require any changes to the rest of the code, since this is just
related to ASM's visitor.
We want to use the stable API 6 for all other plugins, only using the
experimental API when required, so we check the class version first.
This should be removed as soon as ASM API 7 is stable.

fc10dec5 Don't throw error on invalid data in CraftMetaItem.
Fixes GH-1471, GH-1474
As a result, data that no longer parses correctly will not crash the server
instead just logging the exception and continuing (and in most cases should
fix the data)
Player data is fixed pretty much immediately but some block data (like
Shulkers) may need to be modified in-game in order for it to re-save
properly
No more crashing though.
There is no reason for the light queue to even be an option. This
enables the light queue for everyone.
This also improves the "can we still tick" time logic to always
check before running a light operation.
previously, we always executed at least 10 on the first world
(but not other worlds...), but we are seeing light take up some
heavy time, so improving that for now.
I've now also improved recheck gaps logic to happen at the end of all single block updates
This also prevents multiple gap checks, as previously if a tick skipped
the gaps check, the next tick would end up re-adding the entry again,
resulting in multiple gap checks.
This now just sets a marker "We need to recheck gaps" and will only occur
once.
This also should reduce chunk loads, as previously, we checked if
the neighbor chunks were loaded for the gap check, however those
neighbor chunks might of unloaded before the light queue operation
actually ran. Now, the neighbor chunk is done when the gap check
is being done, so it should avoid loading chunks.

Some chunks that need conversion may fail the loadChunks pass, and
end up entering the world gen code to finish processing.
We solved this on the API level before, but this needs to apply to
all chunk loads when gen=false
This adds a new Future based, Consumer<Chunk> based, and ability
to control whether or not to generate to the Async Chunk API.
Until Async Chunks merges, these API's are still synchronous, but
this commit will allow plugins to start using the API's in use
with the Async Chunks beta.

26c89277 SPIGOT-4385: Clearer error for invalid generator-settings
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.
If you try to load a world inresponse to another world loading,
a concurrent modification exception will throw.
This avoids that by making a defensive copy of the list for the server init stage.
you might want to do this if you want to guarantee your world loads
immediately after the vanilla worlds before another plugin has a chance
to load worlds during POST_WORLD plugin stage.
Minecraft moved worlds to a hashmap in 1.13.1.
This creates inconsistent order for iteration of the map.
This patch restores World management to be back as an Array.
.values() will allow us to iterate as it was pre 1.13.1 by
ArrayList, giving consistent ordering and effecient iteration performance.
KeySet and EntrySet iteration is proxied to the List iterator,
and should retain manipulation behavior but nothing should be doing that.
Getting a World by dimension ID is now back a constant time operation.
Hopefully no other plugins try to mess with this map, as we are only handling
known NMS used methods, but we can add more if naughty plugins are found later.
Multiverse was tested with this and no breakage.
Allows you to add to paper.yml
seed-overrides:
world_name: some seed value
This will ignore every where a seed is set/created/loaded and force
a world to use the specified seed.
This seed will end up being saved to the world data file, so it is
a permanent change in that it won't go back if you remove it from paper.yml
It's always been commonly said to 'ignore' that TPS was '19.X', that
it was fine.
I suspect that the inaccuracy of floating point math resulted in us
losing precision over time, making it difficult to actually get back to 20,
as you know the fun 0.1 + 0.1 ... 9 more times != 1 problem.
BigDecimal supports working with doubles with higher precision.
This change makes it so our RollingAverage class maintains all of the data
using BigDecimal and using BigDecimal arithematic operations.
This ensures we have extremely high precision, enabling us to
actually be able print '20 TPS' when TPS is perfect.
