Shane Freeder 90d8377b59 Fix NPE from sign placement (Closes #1963) (Fixes #1917)
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

Shane Freeder 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.

Spottedleaf 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).

Tested via:

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.

Spottedleaf 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.

Fixes GH-1831

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.

Spottedleaf c4ff33a9e5
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.

Restore vanilla behavior of mob counts for persistent mobs
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.

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.

Reuse buffers for chunk compression to optimize memory use
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.

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.

Example Usage: https://gist.github.com/aikar/5bb202de6057a051a950ce1f29feb0b4
