Will now run those tasks just before we print "Done" so that startup
time is appropriately accounted for a plugin, as well as will no longer
trip the watchdog on startup.
Any plugin that tries to bypass this is just going to then trip watchdog
on Spigot too, so don't you dare.
Stop trying to cheat the delay your plugin added to startup time.
This isn't a behavior change because the first thing the tick does....
was run these tasks....
So it's just moving it slightly a few lines to be before a watchdog tick and
to account for it in "Done" time.
Fixes#3294
When adding/removing to a chunk, we need to also look at
editing the loaded entity list.

Removes synchronization from sending packets
Makes normal packet sends no longer need to be wrapped and queued like it use to work.
Adds more packet queue immunities on top of keep alive to let the following scenarios go out
without delay:
- Keep Alive
- Chat
- Kick
- All of the packets during the Player Joined World event
Hoping that latter one helps join timeout issues more too for slow connections.
Removes processing packet queue off of main thread
- for the few cases where it is allowed, order is not necessary nor
should it even be happening concurrently in first place (handshaking/login/status)
Ensures packets sent asynchronously are dispatched on main thread
This helps ensure safety for ProtocolLib as packet listeners
are commonly accessing world state. This will allow you to schedule
a packet to be sent async, but itll be dispatched sync for packet
listeners to process.
This should solve some deadlock risks
This may provide a decent performance improvement because thread synchronization incurs a cache reset
so by avoiding ever entering a synchronized block, we get to avoid that, and packet sending is a really
hot activity.
Undo the accidental renaming of a method in 0aad8bf
Aikar wanted to rename DataPalette#getDataBits(T object) to getOrCreateIdFor
in 0aad8bf 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.
Increases risk of deadlock if a plugin using protocollib sends a packet
async, and then a listener then reads world state, and main thread is then
blocked waiting for the queue to flush.
This will break out of the synchronized block when it jumps to the netty event loop.

Java 9+ doesn't allow using the exposed cleanup method, but added
a new method on Unsafe to do it.
So have to detect java version and use the appropriate strategy.
See: https://www.evanjones.ca/java-bytebuffer-leak.html
This is potentially a source of lots of native memory usage.
We are clearly seeing native usage upwards to 1-4GB which doesn't make sense.
Region File usage fixed in previous patch should of tecnically only been somewhat
temporary until GC finally gets it some time later, but between all the various
plugins doing IO on various threads, this hidden detail of the JDK could be
keeping long lived large direct buffers in cache.
Set system properly at server startup if not set already to help protect from this.
Mojang was semi leaking native memory here by relying on finalizers
to clean up the direct memory.
Finalizers have no guarantee on when they will be ran, and since this is
old generation memory, it might be a while before its called.
This method shows up as super hot in profiler, and also a high "self" time.
Upon analyzing, it appears most usages of this method fall down to the final
else statement of the nasty ternary.
Upon even further analyzation, it appears then the majority of those have a
consistent list 1.... One with Infinity head and Tails.
First optimization is to detect these infinite states and immediately return that
VoxelShapeMergerList so we can avoid testing the rest for most cases.
Break the method into 2 to help the JVM promote inlining of this fast path.
Then it was also noticed that VoxelShapeMergerList constructor is also a hotspot
with a high self time...
Well, knowing that in most cases our list 1 is actualy the same value, it allows
us to know that with an infinite list1, the result on the merger is essentially
list2 as the final values.
This let us analyze the 2 potential states (Infinite with 2 sources or 4 sources)
and compute a deterministic result for the MergerList values.
Additionally, this lets us avoid even allocating new objects for this too, further
reducing memory usage.
We've seen many a cases where the "last good" x/y/z is desynced from
the x/y/z that is checked for moving too fast.
Theory is that when you have multiple movement packets queued up,
and the player is teleported after the first then the 2nd and 3rd come in,
it is triggering a massive movement velocity.
This will ensure that the servers position is synchronized anytime player is te
Fixes#3258
It was still technically read correctly in what it was doing, but
all our Player events begin with Player.
Nothing uses this event yet so safe to rename.
If you are some rapid adopter of this event, sorry :P
If a server enables Anti Xray, packet sending can be delayed until the
chunk has been obfuscated, blocking the entire queue from going out.
On a busy server, considering Anti Xray can only operate on a single
thread, it is quite possible the obfuscation backlog can get quite behind
resulting in a delay of sending packets.
And logging in is a clear area where lots of chunks are going to be queued
for obfuscation....
We should probably special case a few more than this (such as chat),
but this will hopefully help the keep alive issues some people run into.
Now has separate configs to control Villager immunities a bit.
whether or not they wake up due to panic situations (raids)
and when should they wake up when work is available after being
inactive for so long, and for how long.
This work config may make the 'wake up inactive' feature for villagers
useless in most scenarios, but if there is a situation where the villager
does go without needing to work for a long period of time, it would kick
in then.
This also removes movement based immunities, so now villagers should only move
if they trigger a work immunity, panic immunity, or inactive wake up immunity.

If a sync load was triggered, it would process pending join events,
causing them to be added to the world in the middle of the entity ticking
process.
This caused their add to be queued instead of immediate, causing
"Illegal Tracking" errors.
This schedules it to fire at the players next Connection Tick, which
is exactly where this entire process use to run anyways.
Also added missing tab complete and syntax for syncloadinfo debug command

This is the start of a new module for Paper to add support for API's
that interface Mojang API's directly.
This allows us to version properly by MC version incase Mojang makes any major breaking changes.
It also lets us separate Mojang API's from Paper-API so our downstream friends at Glowstone
will not have to worry about Mojang code.
Adds AsyncPlayerSendCommandsEvent
- Allows modifying on a per command basis what command data they see.
Adds CommandRegisteredEvent
- Allows manipulating the CommandNode to add more children/metadata for the client
Calling this 2.0 as it's a pretty major improvement with more knobs to twist.
This update fixes many things. The goal here is to restore vanilla behavior to some degree.
Instead of permanent inactive pools of animals, let them show some signs of life some....
Yes this may reduce performance compared to before, but I hope it is minimal. Got to find a balance.
Previous EAR logic really compromised vanilla behavior of mobs. This tries to restore it.
Changes:
1) All monsters are now classed as Monster. Mojang has an interface, we should use it.
- This now includes Shulker, Slimes, see #2 for Phantom and Ghast
2) Villagers and Flying Monsters now have their own separate activation range configs.
- Villagers will default to your Animals config
3) Added a bunch of more immunities
- Brand new entities are immune for a few seconds
- Entities that recently traveled by portal are immune for few seconds
- Entities that are leashed to a player are immune
- Ender Signals are immune
- Entities that are jumping, climbing, dying (lol) are immune
- Minecarts are now always immune to the movement restriction
4) Villagers immunity received major overhaul...
- Now has many immunities for Villager activities to let them
do their work then go back inactive
- Such as interacting with doors and workstations should be more normal now
- Raids will trigger immunities, in that villagers will run and hide when bell rings.
- Raid should keep the entire village immune during the raid to keep gameplay mechanics
You can disable raids by game rule if you dont want raids
Then the big one.....
Wake Up Inactive Entities:
One issue plagueing "farms" is that we no longer even let entities move now.
Entities become lifeless.
A new system has been introduced to wake up inactive entities every so often, to let
them stretch their legs, eat some food, play with each other and experience the good entity life.
Animals, Villagers, Monsters (Includes Pillagers), and Flying Monsters will now wake up every
so often after staying inactive for a very long. This grants them a temporary immunity, that
the goal is they will then find "stuff to do" by having a longer activity window.
How many to wake up, how often they wake up, and for how long they wake up are all configurable.
Current EAR Immunities really don't give some entities enough of a window to find work
to then keep them immune for the work to even start. This system should help that.
We will only wake up a few entities per tick on the first wave, restoring 1 per type per world per tick.
So say you have 10 monsters qualify for inactive wake up, all 8 will wake up on the first eligible tick,
and then the 9th will wake up on next tick, 10th on next tick.
If for 5 ticks no more inactive wake up, our buffer will have built back up to 5, and then 5 can go next needed tick.
This basically incrementally wakes them up, preventing too many from waking up in a single tick, to reduce impact to TPS.
This was missing Entity Tracking Range support, creating different
values in this section vs normal section.
Concerned this might of caused some carnage on tracker if this code says
"Yes you should track this player 500 blocks away from you on a horse" and then
the other check uses the normal value.
Set:
settings:
- use-optimized-ticklist: false
If you are having issues with block updates and want to see if this fixes it.
