The data provided is always from the regionfile thread, which
does not copy the data out. So if two separate calls need
the data, then there's going to be a problem.
Note that the log4j-api version used in paper-api does not affect the version used in paper-server, this just affects the version people will see in their IDE when compiling against paper-api.

HashMapPalette uses an instance of CrudeIncrementalIntIdentityHashBiMap
internally. A Palette has a preset maximum size = 1 << bits.
CrudeIncrementalIntIdentityHashBiMap has an initial size but is
automatically resized. The CrudeIncrementalIntIdentityHashBiMap is created
with the maximum size in the constructor of HashMapPalette, with the aim
that it doesn't need to be resized anymore. However, there are two things
that I think Mojang hasn't considered here:
1) The CrudeIncrementalIntIdentityHashBiMap is resized, when its initial
size is reached and not the next time, when a further object is added.
2) HashMapPalette adds objects (unnecessarily) before checking if the
initial size of CrudeIncrementalIntIdentityHashBiMap is reached.
This means to actually avoid resize operations in
CrudeIncrementalIntIdentityHashBiMap, one has to add 2 to the initial size
or add 1 and check the size before adding objects. This commit implements
the second approach. Note that this isn't only an optimization but also
makes async reads of Palettes fail-safe. An async read while the
CrudeIncrementalIntIdentityHashBiMap is resized is fatal and can even lead
to corrupted data. This is also something that Anti-Xray is currently
relying on.

Also adds per-world spawn limit config in paper.yml for `underground_water_creature`, and migrates existing spawn limit config options to their Mojang names.
Instead of allocating the 4KB for every chunk section, cache it locally and
reuse it for other chunk sections to save on allocations. These allocations add
up very quickly when saving chunks frequently.
For example, with 30,000 chunks and 16 chunk sections per chunk (which will
actually get larger in 1.18) it allocates nearly 2GB, which this patch
eliminates entirely.

Previously the upstream FurnaceStartSmeltEvent would default to the
recipes cooking time, ignoring any modifications from the furnace speed
multiplier.
While this works correctly for upstream, paper introduces the speed
multiplier API, which allows a different cook time from the one provided
by the recipe.
This commit now passes the modified cooktime to the furnace start smelt
event explicitly, instead of allowing the event to default to the
recipes cooking time, thus ensuring that the speed modifier is
respected.

This re-introduces the issue behind #5872 but fixes#6543
The logic here is generally flawed however somewhat of a nuance,
upstream uses managedBlock which is basically needed to process
the posted entity adds, but, has the side-effect of processing any
chunk loads which has the naunce of stacking up and either causing a
massive performance hit, or can potentially lead the server to crash.
This issue is particularly noticable on paper due to the cumulative efforts
to drastically improve chunk loading speeds which means that there is much more
of a chance that we're about to eat a dirtload of chunk load callbacks, thus
making this issue much more of an issue
Note from Spottedleaf:
Please note that this doesn't fix any problems using dataconverter
because dataconverter does not re-route world gen settings conversion.

This PR contains all of Tuinity's patches. Very notable ones are:
- Highly optimised collisions
- Optimised entity lookups by bounding box (Mojang made regressions in 1.17, this brings it back to 1.16)
- Starlight https://github.com/PaperMC/Starlight
- Rewritten dataconverter system https://github.com/PaperMC/DataConverter
- Random block ticking optimisation (wrongly dropped from Paper 1.17)
- Chunk ticking optimisations
- Anything else I've forgotten in the 60 or so patches
If you are a previous Tuinity user, your config will not migrate. You must do it yourself. The config options have simply been moved into paper.yml, so it will be an easy migration. However, please note that the chunk loading options in tuinity.yml are NOT compatible with the options in paper.yml.
* Port tuinity, initial patchset
* Update gradle to 7.2
jmp said it fixes rebuildpatches not working for me. it fucking better
* Completely clean apply
* Remove tuinity config, add per player api patch
* Remove paper reobf mappings patch
* Properly update gradlew
* Force clean rebuild
* Mark fixups
Comments and ATs still need to be done
* grep -r "Tuinity"
* Fixup
* Ensure gameprofile lastaccess is written only under the state lock
* update URL for dataconverter
* Only clean rebuild tuinity patches
might fix merge conflicts
* Use UTF-8 for gradlew
* Clean rb patches again
* Convert block ids used as item ids
Neither the converters of pre 1.13 nor DFU handled these cases,
as by the time they were written the game at the time didn't
consider these ids valid - they would be air. Because of this,
some worlds have logspam since only DataConverter (not DFU or
legacy converters) will warn when an invalid id has been
seen.
While quite a few do need to now be considered as air, quite a lot
do not. So it makes sense to add conversion for these items, instead
of simply suppressing or ignoring the logs. I've now added id -> string conversion
for all block ids that could be used as items that existed in the game
before 1.7.10 (I have no interest in tracking down the
exact version block ids stopped working) that were on
https://minecraft-ids.grahamedgecombe.com/
Items that did not directly convert to new items will
be instead converted to air: stems, wheat crops, piston head,
tripwire wire block
* Fix LightPopulated parsing in V1466
The DFU code was checking if the number existed, not if it
didn't exist. I misread the original code.
* Always parse protochunk light sources unless it is marked as non-lit
Chunks not marked as lit will always go through the light engine,
so they should always have their block sources parsed.
* Update custom names to JSON for players
Missed this fix from CB, as it was inside
the DataFixers class.
I decided to double check all of the CB changes again:
DataFixers.java was the only area I missed, as I had inspected all
datafixer diffs and implemented them all into DataConverter. I also
checked Bootstrap.java again, and re-evaluated their changes. I had
previously done this, but determined that they were all bad.
The changes to make standing_sign block map to oak_sign block in
V1450 is bad, because that's not the item id V1450 accepts. Only
in 1.14 did oak_sign even exist, and as expected there is a converter
to rename all existing sign items/blocks.
The fix to register the portal block under id 1440 is useless, as
the flattenning logic will default to the lowest registered id - which
is the exact blockstate that CB registers into 1440. So it just
doesn't do anything.
The extra item ids in the id -> string converter are already added,
but I found this from EMC originally.
The change for the spawn egg id 23 -> Arrow is just wrong,
that id DOES correspond to TippedArrow, NOT Arrow. As
expected, the spawn egg already has a dedicated mapping for
Arrow, which is id 10 - which was Arrow's entity id.
I also ported a fix for the cooked_fished id update. This doesn't
really matter since there is already a dataconverter to fix this,
but the game didn't accept cooked_fished at the time. So I see
no harm.
* Review all converters and walkers
- Refactor V99 to have helper methods for defining entity/tile
entity types
- Automatically namespace all ids that should be namespaced.
While vanilla never saved non-namespaced data for things that
are namespaced, plugins/users might have.
- Synchronised the identity ensure map in HelperBlockFlatteningV1450
- Code style consistency
- Add missing log warning in V102 for ITEM_NAME type conversion
- Use getBoolean instead of getByte
- Use ConverterAbstractEntityRename for V143 TippedArrow -> Arrow
rename, as it will affect ENTITY_NAME type
- Always set isVillager to false in V502 for Zombie
- Register V808's converter under subversion 1 like DFU
- Register a breakpoint for V1.17.1. In the future, all final
versions of major releases will have a breakpoint so that
the work required to determine if a converter needs a breakpoint
is minimal
- Validate that a dataconverter is only registered for a version
that is registered
- ConverterFlattenTileEntity is actually ConverterFlattenEntity
It even registered the converters under TILE_ENTITY, instead of
ENTITY.
- Fix id comparison in V1492 STRUCTURE_FEATURE renamer
- Use ConverterAbstractStatsRename for V1510 stats renamer
At the time I had written that class, the abstract renamer didn't
exist.
- Ensure OwnerUUID is at least set to empty string in
V1904 if the ocelot is converted to a cat (this is
likely so that it retains a collar)
- Use generic read/write for Records in V1946
Records is actually a list, not a map. So reading map was
invalid.
* Always set light to zero when propagating decrease
This fixes an almost infinite loop where light values
would be spam queued on a very small subset on blocks.
This also likely fixes the memory issues people were
seeing.
* re-organize patches
* Apply and fix conflicts
* Revert some patches
getChunkAt retains chunks so that plugins don't spam loads
revert mc-4 fix will remain unless issues pop up
* Shuffle iterated chunks if per player is not enabled
Can help with some mob spawning stacking up at locations
* Make per player default, migrate all configs
* Adjust comments in fixups
* Rework config for player chunk loader
Old config is not compatible. Move all configs to be
under `settings` in paper.yml
The player chunk loader has been modified to
less aggressively load chunks, but to send
chunks at higher rates compared to tuinity. There are
new config entries to tune this behavior.
* Add back old constructor to CompressionEncoder/Decoder (fixes
Tuinity #358)
* Raise chunk loading default limits
* Reduce worldgen thread workers for lower core count cpus
* Raise limits for chunk loading config
Also place it under `chunk-loading`
* Disable max chunk send rate by default
* Fix conflicts and rebuild patches
* Drop default send rate again
Appears to be still causing problems for no known reason
* Raise chunk send limits to 100 per player
While a low limit fixes ping issues for some people, most people
do not suffer from this issue and thus should not suffer from
an extremely slow load-in rate.
* Rebase part 1
Autosquash the fixups
* Move not implemented up
* Fixup mc-dev fixes
Missed this one
* Rebase per player viewdistance api into the original api patch
* Remove old light engine patch part 1
The prioritisation must be kept from it, so that part
has been rebased into the priority patch.
Part 2 will deal with rebasing all of the patches _after_
* Rebase remaining patches for old light patch removal
* Remove other mid tick patch
* Remove Optimize-PlayerChunkMap-memory-use-for-visibleChunks.patch

* Revert AT for Vec3i setX/Y/Z

CraftBukkit breaks legacy world conversion in three ways:
- Writes userdata to the path of the userdata folder rather than to
the correct file inside the aforementioned folder. This causes the
userdata folder to fail to be created as a file already exists at
its path.
- Makes changes to how multiworld works, without modifying
McRegionUpgrader to be aware of these changes.
- Calls methods on Bukkit before the server is initialized.
This patch fixes all of these issues, and also threads the
McRegionUpgrader to improve performance.
* Ensure priority updates are determined by current level, not deferred level
Deferral could cause an infinite loop to occur.
Also, re-add the light engine priority logic.
* Rebase

Mojang made some changes to priorities in 1.17 and it seems that these changes
conflict with the changes made in this patch, which in some cases appears to
cause excessive rescheduling of tasks.
This, however, is not confirmed as such but seems to be the behavior that we're
seeing to cause this issue, if mojang has adopted the changes we suggested,
then a good chunk of this patch may be unneeded, but, this needs a much better
look than I'm currently able to do

2cdc6b1e4 SPIGOT-6692: Add sendSignChange overload with a hasGlowingText parameter
When a ServerEntity instance is first constructed, it uses a pre-Java 9 empty collection,
but passengers use Guava ImmutableList. When comparing the two collections via Object#equals
we miss out on an opportunity to reduce the check to little more than a reference equality
check (which is very fast).
The previously existing toBuilder method defined on the CraftMetaBook
would, no matter if called on a writable or written book, return a
builder targetting a writable book, in which complex components, such as
hover or click text are not allowed.
The builer hence serializes the page components using LEGACY_UXRC to
ensure only colour may be passed. While this works as intented for
writable books, the builder fails to fully support the complex
components that may be used in a written book.
This commit implemements a child class of the CraftMetaBookBuilder, the
CraftMetaBookSignedBuilder, which builds to a CraftMetaBookSigned
instance and hence serializes the pages to json.
This builder instance is automatically supplied when calling toBuilder
on a CraftMetaBookSigned instance.
