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.
Please report confirmations on #3145 ticket
This is friendlier to plugins as far as the plugin is concerned,
the inventory did open and immediately closed.
We avoid sending the packet to client so they don't see the window
flash either.
If a plugin wants to avoid wasteful fake opens, they should check
that the player is not sleeping before opening the inventory.
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
This notably fixes the newest "Donkey Dupe", but also fixes a lot
of dupe bugs in general around nether portals and entity world transfer
We also fix item duplication generically by anytime we clone an item
to drop it on the ground, destroy the source item.
This avoid an itemstack ever existing twice in the world state pre
clean up stage.
So even if something NEW comes up, it would be impossible to drop the
same item twice because the source was destroyed.
This should make us more forward proof on preventing dupes.
These dupes have been in for years at this point, they aren't new...
Everyone knows about them and are mitigating with plugins atm breaking gameplay.
so better to make it clear its fixed in the messaging.
I am submitting this to Mojang.
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
* Don't check for Entities with Inventories if the block above us is also occluding (not just Inventoried)
* Remove Streams from Item Suck In and restore restore 1.12 AABB checks which is simpler and no voxel allocations (was doing TWO Item Suck ins)
* Restore missing application of previous optimization to getEntities for Inventoried Entities from CullanP
* Use getChunkIfLoadedImmediately for getting loaded entities (faster/simpler, no risk of sync loads)
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.
Bump chunk priority to ensure chunks load fast
Handle case where client disconnects before they even fire PlayerJoinEvent
- no longer call PlayerQuitEvent or print quit message.
- don't save the player data file if never joined. Nothing has changed.
CraftBukkit has a bug here that if you do save it, you will lose
any horse that the player logged off on because the horse hasn't
been resummoned yet.
ChunkMapDistance polls multiple entries for pendingChunkUpdates
Each of these have the potential to move a chunk in and out of
"Loaded" state, which will result in multiple callbacks being
needed within a single tick of ChunkMapDistance
Use an ArrayDeque to store this Queue
This event is called when processing a player's attack on an entity
right before their attack strength cd is reset, there are no existing
events that fire within this period of time so it was impossible to
capture the players attack strength via API prior to this commit.
The event is cancellable, which will just skip over the normal reset of
attack strength cd
This change lets players who are in their bed have a position which is above
ground for a longer period of time. This is because of the server not setting
their position to the ground/exit location when entering the bed, resulting in
the server believing they're still in the air.
Because we moved entity registration to occur before the PlayerJoinEvent occurs,
We started tracking the entity too early before it was registered to the client.
So delay tracking until after list packets have been sent.
No longer will trigger Synchronous Chunk Loads when a player logs
in to the server.
Will delay PlayerJoinEvent until the chunk has been loaded.
Should have massive performance benefits for larger servers with
lots of players logging in and out.
Confused on this one, as commit history says Spigots version is older
than our version, so i'm not sure how we ended up duplicating this when
the 2 events are 100% identical.
Subclass spigots event and rely on the inheritance system, and clean up
the duplicate event fires.
Fix Spigots setPosition to use setPositionRaw to avoid chunk load prematurely.
