890130b46#746: Add Fluid types / tags
Mojang precaches every single potential rewrite rule that could ever
exist on server startup. This includes rules from all the way back to versions from 6+ years ago.
This is the source of why the server hogs every CPU core at 100% every start.
For anyone who hard resets for updates or has force upgraded their entire world, this
results in completely wasted cpu cycles.
This massive CPU usage also delays server startup time.
We improve this by making "min version to precache" that defaults to a future version
so that no rewrite rules are precached.
someone who expects to be converting a lot chunks could theoretically set
-DPaper.minPrecachedDatafixVersion=<dataVersionConvertingFrom> as a startup
parameter and only build from that point on.
However this will likely never be needed as the server will still run
the same cache logic on demand when it's actually needed. The only
cost would be some delay on the FIRST chunk conversion, but paper already
runs chunk conversions on another thread so this will likely never be
a concern for TPS.
This patch will significantly reduce CPU use on startup, reduce memory usage,
and improve server startup time.

1.16.2 introduced 2 thread pools for Bootstrap vs main we didn't account for.
This also sets Bootstrap priority to be 1 less thread priority too so MC Main threads will always have
more priority specially on servers running multiple instances, since bootstrap tends to use up all CPU.

6f55306c4 SPIGOT-5794: Only skip interact event if position, hand and itemstack are equal
This is a pretty tiny update with very little changed. Recommended to update
from 1.16.2 ASAP as 1.16.2 is now no longer supported.
Plugins should mostly remain working as the NMS revision did not change.
Previously, Entity Activation Range only applied to the root entity of a vehicle chain.
If that vehicle is active, every entity as it's passenger would then tick.
This creates scenarios where EAR does not apply your desired ranges to passengers.
Additionally, any entity that was a passenger never had its inactiveTick method called
when the parent was inactive, creating behavioral desyncs.
This could of been a source of many villager issues when those villagers were in minecarts
as players commonly do.
Now we will process passengers checking their activation state independently of their vehicle
and if they are inactive, call their inactiveTick() method to ensure state remains consistent.
This also helps improve any desync issues with entity position of passengers too.
This also removes immunity for passenger/vehicles, so it should improve performance
of these minecart villagers too for EAR.
This makes it so entities that are passengers of other entities no longer count in the parents timings, as well as
tracks them as a separate timers per their tick status.
This lets you see how much time is spent in activated entities vs inactive (as inactive still has to do work)
Passengers is also tracked separately so you can identify "Villagers in Minecarts" vs roaming villagers, as
the lack of ability to move can impact their performance characteristics.
This will likely break any plugin that was naughty and directly messed with our internal timings as this
moves the timings to the EntityTypes object, speeding up creation of Entities to no longer store
a timing handler object per entity.
This will also change the output of the entities in timings to use internal ID's instead of class names.
If a plugin is broken by this, shame them for doing bad things. Paper will not fix it, they will have to fix it.

Spigot has been stripping the minecraft-server jar down in order to

fastutil. as we use fastutil and offer it as API, this is useless

00bff0270 SPIGOT-5794: Do not skip PlayerInteractEvent
Up to now a simple counter variable was used to iterate through the
hidden-blocks in engine-mode 2 while obfuscating. This results in low
quality obfuscation.
One could for example easily write a hack, which bypasses Anti-Xray
by not showing ores, which have a certain pattern.
Furthermore, engine-mode 1 is slightly optimized by this commit.
However, engine-mode 2 is probably somewhat slower. I did some tests but
I wasn't able to get stable results for some reason. Therefore this
needs further testing.
An optimized random algorithm is utilized to pick random blocks from the
hidden-blocks list. This implementation uses xorshift and integer
multiplication for bounding. The resulting distribution is negligibly
biased because xorshift doesn't generate 0 and integer multiplication
also implies biased results.

PaperMC believes that 1.16.2 is now ready for general release as we fixed the main issue plagueing the 1.16.x release, the MapLike data conversion issues.
Until now, it was not safe for a server to convert a world to 1.16.2 without data conversion issues around villages and potentially other things. If you did, those MapLike errors meant something went wrong.
This is now resolved.
Big thanks to all those that helped, notably @BillyGalbreath and @Proximyst who did large parts of the update process with me.
Please as always, backup your worlds and test before updating to 1.16.2!
If you update to 1.16.2, there is no going back to an older build than this.

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.
The existing regex is too open and allows for the absence of any actual
number data, detecting an NBT entry of just the letter "i" in upper or
lower case. This causes a single-character NBT entry to be processed as
an integer ending in "i", passing an empty String to to Integer.parseInt,
triggering an exception in loading the item.
This commit forces numbers to be present prior to the ending "i"
letter.
This patch was dropped in 1.14 . I couldn't find it in removed so I got it from 1.13
Tested with 30-40 players and works fine with default settings.

Too many people try to disable async chunks thinking its the cure
to some mysterious problem.
It is not possible to fully disable async chunks, and the portion
that this config controls is so minor in the grand scheme of things.
People are needlessly hurting their server following bad advice, so
just kill this config except for the people who might actually benefit from it.
Ensures light priorities are properly processed before processing new
work, skipping the threads queue.
also stops processing work on task submission.
Also drops dead chunks light work to not waste time on work thats going to be discarded.

Fixes per world difficulty with /difficulty command and also
makes it so that the server keeps the last difficulty used instead

Memory usage is a pretty useless value in any modern garbage collector
as the way memory is used makes this information not representive of
any actionable data.
In the recommended GC flags, this memory value will constantly rise until
it is near max and then goes down. This is perfectly normal and expected.
Having this information shown will lead to confusion.
Plus, many servers give this command to end users, which now really might
not want to expose this memory data.
So this disables it unless /tps mem is used, and also requires a permission
node to even run this subcommand.

The setGameProfile method on TileEntitySkull is annotated with the @nullable annotation,
but the skull didn't check for null profiles before attempting to retrieve cached skin.
This bug was introduced by the commit making the skull use spigot's User Cache.
Additionally, CraftMetaSkull also had the same issue with a null GameProfile, so this also
ensures it doesn't break.
The whole CraftPlayerProfile class is not null-safe, it requires a GameProfile that isn't
null so we add a Validation on the constructor, that way it is easier to catch this kind
of issue in the future.
Fixes#3480
Previously it only controlled whether villagers could trade treasure maps.
Now it should apply to loot generated in treasure maps.
We don't unregister treasure maps from the loot table,
since this option is per-world and the table is global.
Instead I just replaced the implementation with a NOP.
Caused the server to revert to the player's overworld coordinates
after teleporting into the end.
Sidenote: The underlying issue is that the move call can teleport
entities and do other things like kill the entity. In the future,
to fix all exploits derieved from this usually unexpected
behaviour, we need to move all of this dangerous logic outside
of the move call and into an appropriate place in the tick method.
This renames the config from enable tnt duping to enable piston duping
Normally we would not have a config for rails and carpet duping, but
the fix for TNT is the same fix for rails and carpet, so they are
having to be covered under that same config.
As it stands, one can complete from the cache if no ID is given. If
there is no ID, it will throw an NPE, as ConcurrentHashMap (which is used
in UserCache) does not support null keys. This should fix any current
and future issues where exceptions are thrown just because a UUID is not
currently given on the profile due to a plugin or server bug/issue.

Adds Netty Channel Flush Consolidation to reduce the amount of flushing
This improves performanceo of netty event loop.
If a problem is encountered with this, you can disable it by adding the java flag:
-DPaper.disableFlushConsolidate=true
Also avoids spamming closed channel exception by rechecking closed state in dispatch
and then catch exceptions and close if they fire.
This should resolve connections getting stuck spamming ChannelClosed in logs and
let them clean up and close correctly.
ensure we add missing player tickets even if already full status
remove the player ticket throttler entirely... causes a lot of issues and
our system handles the role that it was serving now too.

Spigots cache only cached by name which really was not correct...
Additionally, user cache exposes a cache of any player who has logged in
once this session too even if offline.
Also fixed some quirks with Profile API where we might of had textures
in the cache that we didn't even try to look up.
So this should overall help reduce API calls to Mojang.
Sadly, the User Cache doesn't cache textures, but if that ever
changes in future, we would gain benefit there too.
Rewrites the Threaded task logic to no longer use 2 queues and instead
keep a single prioritized queue and do all of a chunks light tasks in a single batch
Fix a math issue in one place (Thankfully didn't seem to really be a common place since didn't notice anything)
This patch fixes a bug in the WorldChunkManagerTheEnd class where the distance
from 0,0 squared overflows the maximum size of an integer. The overflow leads
to hard chunk borders around 370,000 blocks from 0,0. After this cutoff there
is a few hundred thousand block gap before end land resuming to generate at
530,000 blocks from spawn. This is due to the integer flipping back and forth.
The fix for the issue is quite simple, casting chunk coordinates to longs
allows the distance calculation to avoid overflow and work as intended.
We had 2 issues.
1) Log4J2 Shutdown hook seemed to be causing issues as it shutdown logger while we still needed it
2) ServerShutdownThread needs to stay alive until server is shutdown to keep jvm open.
It appears SIGINT is handled differently than SIGTERM, as SIGINT worked correctly.
But this will make both methods work.
Fix bug where mojang has a -90 modifier in yaw resulting in us calculating
chunks to the players left rather than in front of them.
Drastically improve Frustum Prioritization function to reduce lag from its
calculations (Found it was being spammed really heavy on world add/teleport)
Also improved the logic behind choosing chunks to prioritize.
Add Priority tickets to a radius of 3 on any login, world chnge or teleport
This should help improve world load / chunk sending upon a player changing
locations by loading those chunks faster.
Improved the Player Ticket Delayer to be a little bit smarter about delays to
let closer chunks load a bit faster and only delay the farther out ones more.
This update will provide significant improvements to priority of chunks and
reduce the cpu cost of doing these calculations.
Fixes#3530
There is some vanilla level bug where this tracking state appears
to get messed up and player doesn't exists in chunk its trying to untrack.
We returned early to prevent crashing, but I suspect if there was a level being
tracked for the chunk, it got leaked due to the early return.
So going to ensure we clean up the level tracker when this state occurs.
This may help with any leaked chunk issues.
Now supports async chunk access even though doing that is bad
and shouldn't be done anyways since we force you back to main, itll
now just delay the ticket add to main the same way.
Now only add the ticket if the plugin CAUSED the chunk load, so no longer
adds ticket if the chunk was already loaded.
Additionally, cap chunk ticket limits to 1 second (Effectively ignoring chunk-gc config
unless the config is lower than 20 ticks)
Fixes#3533
Obfuscate multiple chunks at a time over the server thread pool.
Will speed up chunk processing when anti xray is enabled.

Like previous versions, plugins loading chunks kept them loaded until
they garbage collected to avoid constant spamming of chunk loads
This adds tickets to a few more places so that they can be unloaded.
Additionally, this drops their ticket level to BORDER so they wont be ticking
so they will just sit inactive instead.
Using .loadChunk to keep a chunk ticking was a horrible idea for upstream
when we have TWO methods that are able to do that already in the API.
Not adding it to .getType() though to keep behavior consistent with vanilla.
In previous MC versions, we had a rather simple internal scheduler
for delayed tasks that would just keep pushing task back until desired
tick was reached.
The method it called to schedule the task changed behavior in 1.14, and now
this scheduler is not working nowhere near what it was supposed to be doing.
This was causing long delayed task to eat up CPU (In Oversleep for example)
Rewrite this to just use the CraftScheduler for scheduling delayed tasks.
Once this was fixed, it became quite clear the code that delayed ticket
additions for chunks based on distance was clearly not right, as it was
tested on the previous broken logic.
So the ticket delay process has been vastly revamped to be even smarter.
Chunks behind the player can load slower than the chunks in front of the player.
We also can delay ticket adding until one of its neighbors has loaded, as
this lets us get a smoother spiral out for the chunks (minus frustum intent).
Additionally on frustum previous commit inadvertently broke frustum trying to
fix an issue when the real fix lied elsewhere, so restore chunk priority so
it works again.
When players are moving in the world, doing things such as building or exploring,
they will commonly go back and forth in a small area. This causes a ton of chunk load
and unload activity on the edge chunks of their view distance.
A simple back and forth movement in 6 blocks could spam a chunk to thrash a
loading and unload cycle over and over again.
This is very wasteful. This system introduces a delay of inactivity on a chunk
before it actually unloads, which will be handled by the ticket expiry process.
This allows servers with smaller worlds who do less long distance exploring to stop
wasting cpu cycles on saving/unloading/reloading chunks repeatedly.
Upon further knowledge of the system, it is known that region files
are closing properly, as well as this didn't help native memory use anyways.
This patch also caused issues compiling on a newer JDK being able to
release the jar to java 8 users.
priority tickets being added at 33 was hurting sync EMPTY and lesser requests.
this was likely the source of recent treasure map issues.
This then further hurt nether portal travel too. lots of oddness around.
This also avoids scheduling a level change on ticket removal when the level
is unchanged, as well as ditches CB's horrible change to not letting
you access an unloading chunk which should be valid to cancel the unload
I'm going make a class, and in that class i'm going to
make a method. And in that method, I'm going to make a local class.
And then in that local class, I'm going to make another inner class.
I heard you like complex class trees.
Massive update to light to improve performance and chunk loading/generation.
1) Massive bit packing/unpacking optimizations and inlining.
A lot of performance has to do with constant packing and unpacking of bits.
We now inline a most bit operations, and re-use base x/y/z bits in many places.
This helps with cpu level processing to just do all the math at once instead
of having to jump in and out of function calls.
This much logic also is likely over the JVM Inline limit for JIT too.
2) Applied a few of JellySquid's Phosphor mod optimizations such as
- ensuring we don't notify neighbor chunks when neighbor chunk doesn't need to be notified
- reduce hasLight checks in initializing light, and prob some more, they are tagged JellySquid where phosphor influence was used.
3) Optimize hot path accesses to getting updating chunk to have less branching
4) Optimize getBlock accesses to have less branching, and less unpacking
5) Have a separate urgent bucket for chunk light tasks. These tasks will always cut in line over non blocking light tasks.
6) Retain chunk priority while light tasks are enqueued. So if a task comes in at high priority but the queue is full
of tasks already at a lower priority, before the task was simply added to the end. Now it can cut in line to the front.
this applies for both urgent and non urgent tasks.
7) Buffer non urgent tasks even if queueUpdate is called multiple times to improve efficiency.
8) Fix NPE risk that crashes server in getting nibble data
Fixes#3489Fixes#3363
Previously maps would load all chunks in a certain radius depending on
their scale when trying to update their content. This would result in
main thread chunk loads when they weren't really necessary, especially
on low view distances or "slow" async chunk loads after teleports or
other prioritisation.
This changes it to only try to render already loaded chunks based on
the assumption that the chunks around the player will get loaded
eventually anyways.
In rare cases, this class could potentially be loaded from
the chunk threads causing it to initialize async and cause errors.
This would then break the server and chunk saving.
So ensure its loaded at start of server to avoid this.
Still needs front end changes to see it yet though.
1) Adds Game Rules per world
2) Adds View distances per world
3) Removes extra garbage on lambda task names
4) Adds more memory information such as native load
5) Adds load average for non crap operating systems.
6) Fixes online mode showing false when privacy=true
7) Adds Data packs loaded
Switch to a standard fixed size ThreadPoolExecutor as we don't use the
advanced capabilities of a ForkJoinPool.
ForkJoinPool does not allow single threads, and really rather not use
2 different executor types based on core count.
Also, change thread priorities so that main thread is prioritized by
the OS at a higher priority than the other threads. May not help too much
but it at least signals the OS the information to know main is more important.
Locks dimension manager to the first world its used with.
WE is creating a temp world and the world ref on that manager
is getting changed to the temp world.
This would of also caused a memory leak of that temp world too.
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
My recent work on serialization is now in CraftBukkit so was able to drop the patch and Paper
is now consistent with upstream.
