The history of how paths work in Win32 is a sad story and shall not be documented here.
Needless to say, Windows hates the temporary file name for jansi's native code since it
includes the version. For git builds, it includes quotes around the actual version. But
alas, the issue apparently doesn't occur if you build on Windows since it removes the
quotes from the git commandline that is ultimately used to build the version string,
because of more Win32 sadness and shame.
Go look at Raymond Chen's blog, The Old New Thing. It's full of Windows oddities and
it will make you want to weep because almost 90% of the world uses this legacy OS from
the 1980s.
Makes it easier to figure out which custom generator plugin hasn't been
updated to a specific version and is spamming you with
UnsupportedOperationExceptions
If the server attempts to load a chunk generated by a newer version of
the game immediately stop the server to prevent data corruption.
You can override this functionality at your own peril.
Allows server owners to use 1.8 (and prior)'s projectile behavior
(ignored shooter's velocity when calculating projectile's velocity).
This patch adds an option "disable relative projectile velocity", which, when
enabled, will cause projectiles to ignore the shooter's current velocity,
like they did in Minecraft 1.8 and prior.
If a player is falling, for example, their shooting range will be drastically
reduced, as a downwards velocity is applied to the projectile. This prevents
players from saving themselves from falling off floating islands, for example,
as a thrown ender pearl will not make it back to the island, while it would
have in 1.8.
While this could easily be done with plugins, too, there are multiple problems:
1) If multiple plugins cancel the velocity by subtracting the shooter's velocity
from the projectile's velocity, the projectile's velocity would be different.
As there's no way to detect whether the projectile's velocity has already been
adjusted to ignore the player's velocity, plugins can't not do it if it's not
necessary.
2) I've noticed some inconsistencies, e.g. weird velocity when shooting while
using an elytra. Checking for those inconsistencies is possible, but not as
efficient as just not applying the velocity in the first place.
3) Solutions for 1) and especially 2) might not be future-proof, while this
server-internal fix makes this change future-proof.
We were not correctly updating neighbour loaded when we unloaded chunks
since we were not actually retrieving neighbour chunks when unloading.

* Only write to cached header in RegionFile if write potentially succeeds
* Fail write if timestamp update fails
This way timestamps should be consistent with their actual last write.
* Simply order the time write before the chunk write
otherwise we end up with an invalid offset on disk, it's better
to have an invalid timestamp
Upstream has released updates that appears to apply and compile correctly.
This update has not been tested by PaperMC and as with ANY update, please do your own testing
CraftBukkit Changes:
84f3da35 SPIGOT-5054: Prevent issue with invalid hanging entities
dfa7583f SPIGOT-4734: Sign placement fails when looking at grass
Looking over the code, this appears to be one "high risk but hopefully
unlikely that plugins are causing this to break", this line is however
redundant leftovers from spigots tick limiter patch, which should be
doing nothing as-is.

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).

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
