Obfuscate multiple chunks at a time over the server thread pool.
Will speed up chunk processing when anti xray is enabled.
Co-authored-by: Aikar <aikar@aikar.co>
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.
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.
Spigot inserted their Slack Activity Accountant in the wrong location
resulting in a chunk being removed from the unload queue, inserted into
the unload map, but never calling the function to finish the removal....
This caused the chunk to become stuck in the unload map if ever hit, because
the unload map was meant to be a TEMPORARY location while it was saving.
Fix this by abort iteration AFTER the current chunk is finisehd processing
Also, improve how aggressive we are at unloading chunks, targetting 10% per tick instead.
These saves are asynchronous so there should be less of a hit here.
While this method has async in it's name, it's not actually meant
to be called asynchronously.... It just means IT will load the chunk
asynchronously without blocking main.
So fix this so that if a plugin calls it async, it forces the request back to main thread.
Fixed issues where urgent and prioritized chunks didn't actually
always get their priority boosted correctly....
Properly deprioritize non ticking chunks.
Limit recursion on watchdog prints to stop flooding as much
Remove neighbor priorities from watchdog to reduce information
reduce synchronization duration so that watch dog won't block main should main actually wake up
probably fixed a deadlock risk in watchdog printing also that was leading to crashes
fixed chunk holder enqueues not being processed correctly
added async catchers in some locations that should not be ran async
Fixed upstream bug where VITAL callbacks that must run on main actually could
sometimes run on the server thread pool causing alot of these nasty bugs we've seen lately!
This build will provide massive improvements to stability as well as even faster
sync chunk load/gens now that priority is correctly set.
Fixes#3435
I believe this brings us back to stable. A lot of complexity was
learned about juggling priorities.
We were essentially promoting more chunks to urgent than really
needed to be urgent.
So this commit adds a lot more logic to juggle neighbor priorities
and demote their priority once they meet the requirements needed of
them.
This greatly improves the performance of "urgent" chunks".
Fixes#3410Fixes#3426Fixes#3425Fixes#3416
Fixed a few bugs, and made numerous improvements.
Fixed issue where a sync chunk load could have its ticket removed and the
priority ticket could expire...
Still not perfect there but better than before.
Also fixed few other misc issues such as watchdog cpu usage, chunk queue update
had risk of double enqueue due to it no longer being a set.
Added much more information about chunk state to watchdog prints.
I see some more room for improvement even, but this is much better than before.

Mark chunks that are blocking main thread for world generation as urgent
Implements a general priority system so that chunks that are sorted in
the generator queues can prioritize certain chunks over another.
Urgent chunks will jump to the front of the line, ensuring that a
sync chunk load on an ungenerated chunk does not lag the server for
a long period of time if the servers generator queues are filled with
lots of chunks already.
This massively reduces the lag spikes from sync chunk gens.
Then we further prioritize loading order so nearby chunks have higher
priority than distant chunks, reducing the pressure a high no tick
view distance holds on you.
Chunks in front of the player have higher priority, to help with
fast traveling players keep up with their movement.
This commit also improves single core cpu scenarios in that we will
now automatically disable Async Chunks as well as Minecrafts thread
pool.
It is never recommended to use async chunks on a single CPU as context
switching will be slower than just running it all on main.
This also bumps the number of server worker threads by default too.
Mojang does not utilize the workers in an effecient manner, resulting
in them using barely any sustained CPU.
So give it more workers so more chunks can be processed concurrently
This change also improves urgent chunk loading, so players flying into
unloaded chunks will hurt a little bit less (but still hurt)
Ping #3395#3363 (Not marking as closed, we need to make prevent moving work)
This commit doesn't do much on its own, but adds a new Java Cleaner API
that lets us hook into Garbage Collector events to reclaim pooled objects and
return them to the pool.
Adds framework for Network Packets to know when a packet has finished dispatching
to get an idea when a packet is done sending to players.
Rewrites PooledObjects impl to properly respect max pool size and remove
almost all risk of contention.
Bumps the Paper Async Task Queue to use 2 threads, and properly shuts it down on shutdown.
This also cleans up the implementation of Async Chunks to get rid of most
Consumer callbacks and instead return futures.
This lets us propogate errors correctly up the future chain
(barring one isn't lost even deeper in the chain...)
So exceptions can now bubble to plugins using getChunkAtAsync
Undo the accidental renaming of a method in e45e15c
Aikar wanted to rename DataPalette#getDataBits(T object) to getOrCreateIdFor
in e45e15c but he also accidentally renamed
ChunkPacketInfo#getDataBitsIndex(int chunkSectionIndex) to
getOrCreateIdForIndex.
Remove chunk-edge-mode and chunk loading entirely from Anti-Xray
The chunk-edge-mode is broken since several versions.
Loading chunk neighbors for chunk edge obfuscation isn't needed anymore.
Unlike in previous versions, these are under normal circumstances already loaded
at the time we need them (plugins for example can bypass this).
Use the modified methods and constructors everywhere
Anti-Xray provides support for the default nms methods and constructors,
which where modified by Anti-Xray to avoid breaking stuff (plugins)
which somehow uses these methods.
However, the modified versions of those methods and constructors should be used
where possible.

Renames a bunch of timings to be more appropriate for the new environment.
Many things dealt with sync loads which wasn't correct anymore.
adjusted timings to be a little bit more accurate here.
Also cleaned up old 1.13 async chunks configs so people won't keep
thinking they can change some of those configs when they can't.
Process loads outside of any canSleep check. Original intent was to
only apply those restrictions to generations but realized I had some
checks higher up the call chain.
Reworked the back off strategy to just run every 1 millisecond per world,
and to apply the per tick limit to generations only.
This guarantees that your chunk will load with at most around 1ms delay.
Additionally, fire midTick processing in a few more places, notably the
oversleep section so we can keep processing loads here too which has
a large up to 50ms window...
Speaking of oversleep, we had a bug in our implementation changes for
Timings that caused oversleep to not sleep the correct amount.
Because we now moved it into the NEXT tick instead of THIS tick, the
value of nextTick had already been increased to +50ms, resulting in
the risk of sleeping more than it should, but, more importantly, this
caused every task that was trying to NOT run during oversleep to actually
run during oversleep.
This is now fixed.
Another small tweak is to the /tps command, to no longer show the star when
TPS is right at 20.
Due to ineffeciencies in the sleep precision, TPS is commonly 20.02.
This causes the star to show up almost constantly, so now only show it if
we actually hit a real "catchup".
This commit also improves the changes to the CallbackExecutor, in that
it now is also recursion safe.
It was possible that the executor could run tasks out of desired order
if the executor task scheduled more executor tasks.
We solve this by ensuring new additions do not enter the currently iterated queue.
Each depth level will have its own queue.
Fixes#3220
We still keep vanilla process of waiting for existing session to be removed before logging in
by storing a separate map of pending.
also fire the callback using executor incase further recursion causes any trouble
I feel sorry for those who need to do this, and now feel sorry more
since back to slow startups again.
There is keep-spawn-loaded-range in paper.yml to reduce the range to
mitigate this if you must keep async chunks off.
If the request to shut down the server is received while we are in
a watchdog hang, immediately treat it as a crash and begin the shutdown
process. Shutdown process is now improved to also shutdown cleanly when
not using restart scripts either.
If a server is deadlocked, a server owner can send SIGUP (or any other signal
the JVM understands to shut down as it currently does) and the watchdog
will no longer need to wait until the full timeout, allowing you to trigger
a close process and try to shut the server down gracefully, saving player and
world data.
Previously there was no way to trigger this outside of waiting for a full watchdog
timeout, which may be set to a really long time...
Leaf informed me this could cause ordering issues.
So, the risk if this occurring is lowered now anyways, but if an
entity causes a sync chunk load, it could process an unload...
We will tackle the problem better in a future commit
Also fixed another async-chunks=false issue
This fix is for the few people who are using such low end systems that
asynchronous chunk loading hurts them rather than helping.
The previous build made paper crash if you turned off async chunks, and
this fixes that issue.
In most cases, this change won't benefit much. However, there
exists the possibility that your Chunk Task threads are all busy
doing super slow work such as converting chunks.
If this occurs, the main thread blocking tasks, even at highest priority,
has to wait for some thread to become available.
This change gives us a waiting thread used only for main thread blocking
tasks, as well as an increased thread priority level, so that the OS
will give priority to this thread over the other threads.
This is more about guarantees, and won't be any real performanc boost
to anyone who has low or fast activity on their chunk tasks anyways.
But not all of us force upgrade our worlds, and this can be a life saver.
also reordered some patches because multiple PR's were merged.
The entire reason the if statement exists is to only flush and print when done if flag is true
This avoids /save-all from hurting as much as it was before, such as from backup plugins.
This was not applied correctly, and would completely blow up chunk entity
registration if this feature was turned off....
Additionally, change how the entities are removed to be more consistent with other code.
Surface some of the logs indicating there is a problem as we are having so many issues with
entities that we don't need to be surpressing logs like that.
