[PaperMC/Folia] New comment on pull request #181: Fix incorrect entity scheduler retring issue

provide a reason why this change is to be made? why are we avoiding retiring the scheduler of players who have been in the world but are in the change state?

It will cause a crash if the player in configuration state and doesn't reply the keepalive from the server for more than 30s.

Like this(offline mode):
C -> S handshake
C -> S loginstart
S -> C loginsuccess
C -> S login acknowledged

S -> C Keepalive
C: Do nothing and keep this state and connection active(send something e...

[PaperMC/Folia] New comment on commit `6928284`

Reducing the required player spread is a great direction in my opinion! Previously single wandering player would connect regions and cause lag for them from time to time.
Does it have to be based on view distance though? The ticked simulation distance is set lower than view on almost all servers. If players were able to see further, they would feel less restricted and more encouraged to build. This is especially noticable on recent minecraft versions with huge mountains and valleys.

[PaperMC/Folia] Issue opened: #182 Can I restore far lands?

Is your feature request related to a problem?

Folia seems to be very suitable for loading far lands. But I can't find a teaching mechanism to restore this on it.

Describe the solution you'd like.

I want to change some code to restore far lands, or even change the location where it appears.

Describe alternatives you've considered.

I want to use farlandsagain to restore this mechanism, but this plugin does not support folia.

[PaperMC/Folia] New comment on issue #170: rcon-cli broken

I think even if we had a "fire and forget" option that would be great, as already mentioned, even today with Paper you can not really rely on RCON anymore for request<>response operations, but it is useful to send commands. We usually then read the results from the DB (most plugins will write to the db, but they do not action of 3rd party writes to the db)

These are plugin issues, not a Folia bug. You're also running an offline mode server. This issue has been closed and won't be re-opened.

Where you are see plugin error? YOU check my new replaced log error?

Does the region scheduling work based on the global executor and or so how is the scheduling of the regions like activity or inactivity, that might be how the task is getting scheduled, I am running a small custom version that only changes the Async event where i'm passing some data, I can implement debugs to look at the issue further just lmk if you have anything in mind.

[PaperMC/Folia] New comment on issue #193: Ticking mechanism small issue on schedule end and the values

For knowledge this issue turned out to be two things:

  • Overloaded system which caused the #parkNanos to wake up after the long diff, causing the tick to endup running a "long" time later and then not completing the wanted 20tps.
  • After also switching to a low latency kernel this helped a bit, as well as fixing some small thread switching overhead also helped. (This is nice and should probably be in the readme too - overallocating threads wil lcause tps issues due to overloading the JVM).

[PaperMC/Folia] New comment on issue #198: nether portal cannot load chunk centered on itself 3*3 chunks as vanilla

Any mechanic that relies on precise timing of these tickets cannot work on Folia. The ticket is added before the entity is teleported, but Folia adds some number of ticks of delay before the entity arrives to the target location. This doesn't take in account the fact that regions tick in parallel and as a result there is no synchronisation in the ticks between them.
Folia additionally enforces that the chunks in the entity's bounding box is loaded, which may add yet more delay after the tick...

I actually can't see what's going on here, what should I be looking for?

yaw/pitch are ending up to be wrong values, so whenever you throw a pearl, sometimes it'll screw the head rotation and position likely too, so when you're tping even tho you're looking directly to lets say south, on the other POV it'll be NORTH or other direction (north is just example not static).

Spottedleaf Towny has adapted already to the change so it's not a pressing matter any more. I am curious as to why it was working before the 1.20.4 versions. Did your team close a loophole?

more checks are added to protect the server from entering an unknown state, for which it needs to crash to escape safely without any data corruption

The more there are such checks, the less crashes caused by random plugin actions will happen

[PaperMC/Folia] New comment on issue #105: now working API, show me analog

The respawn and teleport APIs are very awkward since the target region for the respawn position or teleport location are not actually owned during the event invocation, which may make modifying the event outcome or even reading from it very challenging. It requires a different event system to properly facilitate this, which is not a priority currently.

EntityPortalEvent doesn't work either

Bug not working is a bug, huh? "vanilla mechanic" lmao

It depends on how you view a thing, it can be a feature or a bug.

We all know that beds will explode in the nether and the end since the nether and the end dimension was implemented. Base on your logic it should be a bug, but Mojang decided to added the "Intentional Game Design" message during 1.13 in case someone don't know it is not a bug, it is a intended behavior.

Folia do allow duplication as a feature in case you don't k...

[PaperMC/Folia] New comment on issue #219: Server crash on player disconnect (something in PlayerQuitEvent)

I tried to reproduce this issue on full empty server, only with plugin with PlayerQuitEvent, tried to teleport player to different worlds, but there is no crash.

But I can still reproduce this crash with my plugins on clear folia. This stack traces doesnt contains my methods, that is why I created this issue

This server is running Folia version git-Folia-"25ee657" (MC: 1.20.4) (Implementing API version 1.20.4-R0.1-SNAPSHOT) (Git: 25ee657)\nYou are running the latest version

player.teleportAsync(loc)
player.getInventory().clear();
player.getAttribute(Attribute.GENERIC_MAX_HEALTH).setBaseValue(20);
player.setHealth(20);
player.setFoodLevel(20);
player.setSaturation(0);
player.setExhaustion(0);
player.setFireTicks(0);

for (PotionEffect effect : player.getActivePotionEffects()) {
player.removePotionEffect(effect.getType());
}

these actions on a player quit are kind of "dumb", you should schedule those actions for the new player join event instead

[PaperMC/Folia] New comment on pull request #220: update paper 1.20.6

https://github.com/KyoriPowered/adventure/releases/tag/v4.17.0 was just released

I found it. But upstream paper using 4.17.0-snapshot in api, and 4.16.0 in server. I noticed in server build script have a commnet saying "Keep in sync with adventureVersion from Paper-API build file".

So I'm not sure if it should be modified in folia patch, I think maybe its belonging to paper's patch?

This has been fixed by [Paper](https://github.com/PaperMC/Paper/commit/5729b294eef2ffd...

[PaperMC/Folia] New comment on pull request #220: update paper 1.20.6

Migrations from folia's patch are done, there still a syntax err in net/minecraft/core/dispenser/ProjectileDispenseBehavior.java line 48 DispenserBlock.eventFired should use get() to fetch bollen type. I leave it alone, because it doesnt changed in folias patch, I think it's upstream's work.

Anyway, patches can be compiled allreday, but I found server stucked when preparing level (I think I may need some help).

enable debug in server.properties or attach a profiler which can do exception recording

but, large PRs should generally be cleared by leaf first, not sure how much acceptance there is towards pulling in an update from somebody else

Is he on vacation now? There is no information when we will be able to get a review of this PR or update to 1.20.6?

Fine, I got new problem.

Any commands send by client will cause "Internal Exception: java.lang.UnsupportedOperationException", and then kicked. Commands send my console is ok.

This fault has no stacktrace, just "Internal Exception", I dont know how to debug it.
You can attach exception catchers on the netty threads, that'll be usually it unless you're testing with plugins iirc you're not it seems, I'll get on development in your branch too, to help test out and get it ready.

The earliest you can schedule a task on an entity is for the task to run the next time the entity ticks. You can't perform the operation immediately because you need to run the packet logic within the entities context.

The behavior here is going to be different because on a vanilla server where there is only 1 thread, you don't need to worry about dispatching packet handles into the correct thread context, there only is 1, and so you can just use the shared task queue which allows pa...

The only current mechanism for ensuring that you get into that context is the entity scheduler, the thing is that the scheduler can only promise to run a task on the next tick. as regions do not spin wait between ticks, there is no mechanism to "immediately" post a task to run against an entity in a fast manner, and you have to remember that entities are not strictly held to a region, and so anything region based is also going to be precarious

[PaperMC/Folia] Issue opened: #250 why does it take so long at all?

Expected behavior

Possible reason is that you rewrite big portions of the game such as chunk system every time! Even worse, only one person works on all of this... this is BAD, such software can not rely only on one person, other maintainers don't even have a clue about changes.. Stop rewriting everything! Give us normal update!

[PaperMC/Folia] New comment on issue #252: Release 1.21 and make update faster!

Folia is not production software, it's basically a single person personal project, there's no guaranteed updates, no support, and no official builds. If you want it updated, update it yourself, or wait.

If a server uses Folia such as 2B2T or DonutSMP it's their choice to use software which may never get updated again, they are able to update and build it themselves.

I played in this server, and I would like to provide more information on the player side.

As we observed, The server will need to run for more than six(6) hours to present a sudden TPS drop (as low as <1.5). For players in the server, the TPS would drop to 1~2 for few seconds, then backs to normal(~19.5 TPS) for around 15 seconds, and repeats the malfunction. As about 15 minutes pass, the frequency of this malfunction becomes higher and the normal TPS time shortens to about 5 seconds. Duri...

you haven't ran save-off have you? otherwise, something is keeping millions of entity instances around, would really need to see a heap dump to see where it's coming from, not that I can offer much

I think nobody run /save-off. On my server only /save-on always

Someone will always use a command if it's available. For example save-off and save-on during backups makes sure that the server does not make any changes to whats going in the backup while it is being done.

I found the problem, yes there is more than this log. It is caused by the BadOmen effect. This error and crash still continues in version 1.21.1.

I doubt it's because of vanilla mechanics. Specifically here the call happens on the API.

Check the logs on the number I tagged. The log here is misleading. It comes entirely from badomen.

In Minecraft version 1.21 and later, when an entity uses an End Portal to enter the End, blocks placed on the Obsidian Platform should turn into item drops rather than disappearing. This ensures that valuable resources are not lost during the portal transition.

[PaperMC/Folia] New comment on issue #283: Memory Leak | Leaking all entities references?

I totally agree with you. I have this problem with 1.21.1. I never had this problem with 1.20.4. I migrated my server to 1.21.1 and my server is essentially a vanilla server that aims for high entity without compromising on the experience. I use the same plugins but with the latest version 1.21.1 I can't keep my server up for more than 7-8 hours because all my ram is empty and I have to restart the server.

[PaperMC/Folia] New comment on issue #285: Developer mode flag

I'm pretty sure your runOnEachRegion example would require locking the regions while it runs to prevent them from merging or splitting in the middle, all regions would have to stop ticking to process this.

Also, this is like 3-8 issues in one, you should split it up in to API requests, documentation requests, and server feature requests (the flag).

I am not sure how to describe. If for example you have a chest full of
blocks and you mine the chest you would expect all the blocks that where in
that chest to be there but that is not always the case. Same thing happens
if you are mine a lot of blocks quickly but not picking up all the blocks
while another player observes. The observing player can see some of the
blocks that where not picked up will randomly disappear in a short period
of time

Why would you care about random users comments? If some "maintainer" closes an issue then OK, that's their business. Otherwise I don't see why you would want to close own issues if there were valid reasons to open them at the first place.

Because that's from the Paper team.

The person who has replied to you on both Discord & previous Github issues, is in fact, not part of the Paper team.

This is complete nonsense. How do you expect the dev version to reach the official version 1.21.1 without people reporting bugs and issues on dev? With magic that will find and fix bugs?

[PaperMC/Folia] New comment on issue #198: nether portal cannot load chunk centered on itself 3*3 chunks as vanilla

Any mechanic that relies on precise timing of these tickets cannot work on Folia. The ticket is added before the entity is teleported, but Folia adds some number of ticks of delay before the entity arrives to the target location. This doesn't take in account the fact that regions tick in parallel and as a result there is no synchronisation in the ticks between them. Folia additionally enforces that the chunks in the entity's bounding box is loaded, which may add yet more delay after the tic...

I'm sure that I'm using Folia. It isn't relevant to what version of Java but server core, cuz I used such JNIC obfuscated plugins on Spigot/Bukkit without any errors.

[PaperMC/Folia] New comment on pull request #308: Modify CraftWorld#getChunkAt(x, z) to functional by sync operation.

For multiple versions CraftChunk is just a wrapper around coordinates (like CraftBlock) without any real information or reference to the chunk. Just create craft chunks in getForceLoadedChunks() with the coordinates without loading them (and they're most probably already loaded anyway), there is a SeverLevel,int,int constructor that you can use instead of the one that takes LevelChunk

[PaperMC/Folia] New comment on issue #302: Piston move block may cause ghost block on Folia 1.21.3

I did have this problem i tested with fresh folia server no problem even when apply my server settings to it no problem.

The cause that i have kinda found to make that happen 100% all the time is that have the
Gamerule spawnChunkRadius 0

When set it to 0 and you fly away unloading the chunk with piston it cause ghost block

When set the spawnchunk back to default 2 (i think) this problem havent happen again.

Expected behavior

TNT explosion event is the same as vanilla

Observed/Actual behavior

In the latest version 1.21.4 of folia and paper, TNT explodes earlier than in vanilla

Steps/models to reproduce

Ignite the TNT, it will be a few tenths of a second earlier than vanilla.

[PaperMC/Folia] New comment on issue #314: Using Spectator Mode player navigation menu will crash the server.

Maybe is because of Paper Teleport API is broken on Folia... I don't know.

I know many parts of the API are broken, but as far as I can tell its a bug and not a feature.
I see Stabrinai mentioned #173 as its the same problem or similar, I saw that is closed now so this should stay open IMO.

If I can help with further testing please feel free to reach out to me

[PaperMC/Folia] Issue opened: #317 Regions occasionally stop sending entities to the player

Expected behavior

Items from broken trees, as well as mobs and other entities, should be properly tracked and send to the Player's client so they can be displayed.

Observed/Actual behavior

Occasionally, regions will stop sending these entities to players, resulting in a confusing desync where you can pick up items but never see them on the game / hear them get picked up.

Steps/models to reproduce

Unsure, though this is occurring at high player counts (we've been running at 130 - 400 players)

[PaperMC/Folia] New comment on issue: #317 Regions occasionally stop sending entities to the player

I'm a bit suspicious that Chunky may be doing something strange that's upsetting Folia somehow with how it's generating/saving these chunks on occasion. @ItsSyfe Was your world pregenerated on 1.21.4?

During my testing on 1.21.3, I had not pre generated any of the land and I don't believe anyone encountered any issues similar to this. The player counts were much lower so the regioning wasn't super active, but nevertheless I don't recall the issue occurring. It's also possible this is some sort of 1.21.4 problem in particular, but I'm unsure.

[PaperMC/Folia] New comment on issue: #324 Folia 1.21.4 - hardfork: net.minecraft.ReportedException: Ticking player

Can still reproduce

Using spectator mode and fly more than 1024(make the final position in other tickregion) and switch to creative mode immediately then it will throw that error

how do you switch to creative mode? from by plugin or operators?

/gamemode creative ()

Can I have an updated log?

Might related with a fix of mojang: https://bugs.mojang.com/browse/MC-92875 And updated logs are above()

[PaperMC/Folia] New comment on issue: #320 In a Zombified Piglin Farm, Zombified Piglins spawn in places they shouldn't.

also notice that 2d goldfarm there sometime piglin walkign aroudn the area outside the killchamber

But it could just be a vanilla feature

minecraft.wiki/w/Zombified_Piglin#Reinforcements

This feature is exclusive to Java Edition. On hard difficulty, zombified piglins have a 5% chance to spawn as leaders. Leader zombified piglins can spawn other zombified piglins as reinforcements.

After looking at this other related issue (https://github.com/PaperMC/Paper/issues/12057). this looks to be the case to me, this is not a bug.

[PaperMC/Folia] Issue opened: #327 Issue with removing player.

Expected behavior

The method isInWall is not doing a thread check for the whole range. this is weird because this causes players to not be removed from the server due to doTick() getting called.

[PaperMC/Folia] New comment on issue: #329 Async was trigger when players teleport to the edge of a tickregion

So I still can't reproduce on new version of fork and with a default value

Error seems disappeared when set grid-exponent to 2

Just like a default?

Default value is 4 in folia1.21.4()

Really? I'm set very long time ago to:
threaded-regions:
grid-exponent: 2
I will try with a default value (4)

In older version it is 2 but I don't know when it was changed to 4.I tested with new generated default config and it'4

[PaperMC/Folia] Issue opened: #330 PlayerTeleportEvent

Expected behavior

The event should either not get called, or when cancelled it should properly handle the location, currently
it seems to be glitching.

Observed/Actual behavior

The blocks call relativeTeleport on the BLock for farms if you jump on them.
and if the event is cancelled, the teleportTo becomes out of the region.
Ideally likely to remove the call of the event

Steps/models to reproduce

Just jump on a block and cancel the event
