folia-help

[grim patrol]

oh ok

thanks

[deft storm]

How can I build a runnable jar of Folia please?

I tried this way, but I had an error. Is there any documentation to do so?

[grim patrol]

is it possible/safe to pre-load (using Chunky plugin for example) map on folia server? And then set worldborder using ChunkyBorder?

[little sable]

Chunky work on Folia

[viral stone]

did you apply patches?

because that error would suggest that you failed to setup the project properly

[deft storm]

Oh, no I didn't

Okay it's done

Thank you, it works correctly. I did not know I could use the Paper documentation to build Folia 😅

[opaque rose]

guys how do you solve the problem that spark can't use in folia?

I've been plagued by this problem for a long time

[livid crag]

Use the branch of spark that supports it. @opaque rose

[pallid radish]

how do i build Folia?

same way as paper?

[inner swift]

Yep

[opaque rose]

Unfortunately I didn't find it

[arctic bear]

🤔

[tulip swift]

i want to allow players to fly (by using cheat clients) but limit the speed to prevent lag, is there any plugin for this?

[idle furnace]

made something for that , check coolprotection, there is a config for that, you can disable all the rest

[tulip swift]

does it support folia?

[arctic tapir]

try it?

I have no clue what that’s supposed to be

[idle furnace]

yes

2.0.1 version

updated description, thanks for the notice

[nimble shell]

how i can download folia

i want to test some plugins with it

[arctic tapir]

you build it yourself

see papers readme

[tawdry gull]

⚠️ Please do not share any links to builds of Folia at this time. We are intentionally not providing easy to find/obtain downloads right now - when the time is right, everything will be available through official PaperMC distributions.

[keen gale]

not a link but it's a pretty clear method to getting folia

[viral stone]

if you're asking for a build, clone the repo and follow the same build instructions from the paper repo on it

[keen gale]

no no not asking for a build, that was in reference to someone mentioning FoliaToGo

which is basically saying just get it from here you don't need to build

[viral stone]

So, they're referring people to a link rather than just providing a link straight up

same difference with extra steps

[keen gale]

ah ok, just thought it might not be allowed

[viral stone]

Yea, no, sorry; I complete brain fart, we generally ask that people don't provide links or point people to links

[keen gale]

👍

[little sable]

Hello, I have a question. I realized that with large farming machines, a single region could use 1 Core CPU on its own. So, is it possible to "limit" the maximum load a region can take?

[finite hinge]

Just the standard ways you would limit a paper server, I guess?

[little sable]

we can limit to a certain extent. here I am talking about intentionally limiting the physical load of a region that Folia uses

[bold osprey]

other than manually put the thread to sleep for like 10-50ms and allocate more threads from the start idk what could you do

(and yeah, this ofc will create lag spikes in that region, but will lower the cpu usage)

[viral stone]

Well, basically, no, not without basically utilising plugins that would prevent things like redstone events (of which many of them can hurt the performance more than they help)

[little sable]

ok I was wondering, thank you very much

[calm nest]

Hi, wanted to ask, is Folia 1.21.1 out already?

[gentle raven]

yes its on the dev/1.21.1 branch

[terse dock]

Does folia compromise vanilla features bc it is a fork of paper?

[finite hinge]

Yes, it has all the same issues of Paper there plus more, like command feedback not working so you can't use command blocks or datapacks that rely on getting the result of commands

I think that's the main vanilla breakage though, the rest of it is API breakage

[visual trail]

Do Folia plugins work with paper plugins?

Sorry, I mean do paper plugins work on Folia*

[silver sierra]

plugins must explicitly add folia support and mark themselves as such in their metadata

paper-plugin.yml supports the folia-supported field if that's what you mean though

[prime juniper]

Does the Folia still far away from the official public builds? Like, will it take at least 1 more year? Or we are more close now?

[tawdry gull]

__There Is No ETA__

Updates to Paper do not have any sort of estimate for when they release, ever. Any and all updates will arrive when they are ready, and the only thing to do is wait for them patiently along with everyone else.

ETA means 'Estimated Time of Arrival'!

[wet arch]

basically, "no one knows"

[manic quarry]

if you can't compile it or have someone compile it for you, you probably can't handle running it

support for folia is still very, very scarce in plugins

you will need custom plugins in most scenarios

[wet arch]

as well as a developer to deal with any issues that arise

[calm nest]

but how do i clone the branch?

[arctic tapir]

google dot com

[calm nest]

omg, instead of actually helping in a help channel, youre telling me to type google dot com. thank you for helping me. wow.

[wet arch]

see here

[viral stone]

clone the repo with git, and then checkout that branch, and run the build script akin to the paper repo readme

[obtuse basin]

If you don’t know how to clone a fit repo you probably shouldn’t use it.

[wet arch]

fit repo

[obtuse basin]

Auto correct isn’t a software engineer it seems

[onyx creek]

I’m experiencing the same issue on my Folia server. There are no plugins installed, and the render distance is set to 8 chunks. However, even when walking around the world, the internet usage stays above 500KB/s, and my ping spikes. Does anyone know how to fix this? Please help!

[chrome loom]

got a spark profile, or at least some hardware specs? 500 kbps is normal, pretty ok for 1 player.

[onyx creek]

On my Paper server, when I walk around with an 8-chunk render distance, the incoming data stays at a maximum of 70 KB/s. However, when I do the same on Folia, the incoming data skyrockets to around 500 KB/s along with high ping spikes.
I'm using a physical server with 64 GB of RAM and an i9-13900 CPU. Neither of the servers have any plugins, and both are connected to a Velocity proxy.

[last gale]

well, as I got answered, folia does do any networking so it should be folia's problem. Also it only one player, the rest of the 30-40 players were okay.

[young burrow]

and also having the regions suddently dies thing i guess because regions do suddenly have every increasing mstp increase

[fair merlin]

When it happens again, get a log and send it here. Spark report would be helpful as well.

[young burrow]

alr

[fair merlin]

Wait, your server is in offline mode?

[young burrow]

no

6b6t.ca

[fair merlin]

Not familiar with the server, but when I go to the website and click on wiki it sends me to a an "8b8t page" which says "8builders8tools, also known popularly as 8b8t, is a semi-vanilla cracked Minecraft anarchy server, based on the 1.21.1 version of Minecraft. "

[young burrow]

the wiki is outdated

i own multiple servers tho

[fair merlin]

So just to confirm, your server does not allow anyone to join unless they own a Minecraft account, correct?

[young burrow]

ye

its a bedrock / java server

[fair merlin]

Well send a log and a spark report when the issue happens again then.

[gloomy vault]

Hello, is there a plugin that, when you die u spawns in an X radius of blocks and not in a single block?

[green moon]

Hi, does anyone have the guit 1.16.5 from Folia?

[fair merlin]

There is no 1.16.5 Folia.

[last depot]

who works on folia developement?

[timid grotto]

mainly leaf

[onyx creek]

BetterRTP

[fair merlin]

Not sure why you would, once again, mention forks here when the question was specifically about Folia.

We do not endorse or condone anyone using a fork of Folia, especially forks that have unsafe practices.

[livid crag]

Slightly off topic, but I think if you have a fork, you should have your own discord for discussion. We encourage people to contribute back with PRs, but solely exist in a support channel to shill your fork or options in your fork just strike me as a bad taste. (Not directly at you but I’ve seem it happen in many mc communities)

[finite hinge]

Eh, I dunno, they weren't saying to use the fork

It would be good to make a PR, if nothing else that would let you know if leaf thinks your solution would actually work

But I suspect most serious folia users have their own fork anyway

Or are at the level where having their own fork isn't a big deal

[last depot]

idk where is the problem in making their own fork? the main reason for the question is because the pr section was kinda of empty compared to paper

but it is cool that other people are working on it

[last depot]

i suspect that most server that use a folia fork just keep their work private tbf, as they have their own dev team

[finite hinge]

There is no problem with making your own fork but if you're trying to get people to use it we don't want you to use this discord for that

Or trying to get help with a fork

[livid crag]

Exactly. It’s basically self advertising in name of “providing support”

[finite hinge]

But with folia sharing patches like that is not really the same as telling you to use a fork, I dunno

[fair merlin]

Zero problem with making a fork. We provide a lot of tooling to help people make forks.

It's suggesting a fork constantly or bringing up the fork when no one asked that's the weird part.

Just doesn't really make sense in the context of a help channel.

People are here to ask for help and questions about Folia. When someone says "Who works on Folia" there's a clear answer. Talking about other projects is at best distracting.

[finite hinge]

#folia-help isn't even supposed to exist, it's just a place to funnel people so they won't put requests to help compile it in to #folia-dev 😛

[fair merlin]

Pretty much.

[fair merlin]

Yeah, this exactly.

I do think most big servers running Folia are likely to have their own fork.

We've seen a lot of instances of that here.

[last depot]

i find it a bit sad that many big servers that use folia don't end up contributing just because "i have my own dev team", it creates a very closed community/circle

[fair merlin]

For sure. But the question was specifically "who works on Folia?" and you answered with a statement about forks.

I don't want to go around in circles on this, especially in a help channel. We are not anti-fork, we are anti-suggesting unsafe stuff to general populace in help channels, and tangental suggestions that aren't related to the questions asked.

[fair merlin]

A lot of the bigger servers are making changes to Folia that Leaf probably wouldn't accept as a PR. People tend to disable safety checks and things which aren't really what you want people doing.

If you know exactly what you're getting into you can push the envelope on some stuff, but it's not something you'd want everyone to be using/doing.

[marsh zealot]

Yo hey there guys, if been running in this issue for the past week and I'm quite desperate at the moment to find a solution to this problem, but I can't figure it out. If you need more system information and stuff, just ping me. If I am wrong in this channel here, I am sorry for the disturbance

[fierce knot]

message.txt by @marsh zealot: https://pastes.dev/Em0jls3tdf

[fair merlin]

At first glance it looks like an issue with zEssentials

[marsh zealot]

Welp ok, thanks. I hoped it was something else. Seems like I will have to start searching for alternatives.

Appreciate the fast response tho. Enjoy your day, evening or whatever.

[runic eagle]

im having normal essentialsx and cmi also lol

but what im looking for is multiverse core

[runic eagle]

btw im also having lp

btw im here to help anyone releated to folia

[fair merlin]

Not really sure what you're saying or asking for here.

[runic eagle]

im looking for multiverse core folia supported

[finite hinge]

Folia cannot load/unload worlds at runtime, only load them at startup from datapacks

[runic eagle]

💀

rip

i hope someone soons make it work

[finite hinge]

Unlikely, it's a major thing

People have hacked in the ability to load worlds in forks which kind of works sometimes if you're careful about when you load them but unloading is still out of reach

[runic eagle]

really?

cine

btw i dont want to load works while running

i just wanted to setup multiple worlds

like for login

[finite hinge]

Then you don't need multiverse, just make a datapack

https://minecraft.wiki/w/Dimension_definition

https://misode.github.io/dimension/?version=1.21 is a tool to make them, it has presets to mimic the overworld and such if you just want a vanilla world

{
  "type": "minecraft:overworld",
  "generator": {
    "type": "minecraft:noise",
    "biome_source": {
      "type": "minecraft:multi_noise",
      "preset": "minecraft:overworld"
    },
    "settings": "minecraft:overworld"
  }
}

Not much to it

[dawn marsh]

does folia support 1.21.1?

[hexed ice]

there is a 1.21.1 dev branch

[short compass]

Has anyone encountered this where blocks cant be mined and items cant be picked up in some chunks until they get unloaded?

[short compass]

Yeah the tps didn’t show anything weird

1.21.1

And when you teleport away for a few minutes and go back, it’s fixed

[little sable]

This happened to me on my Skyblock server too, I restarted the server and the problem did not reappear.

Tps was 20

[prime juniper]

https://modrinth.com/plugin/morefoworld

[marsh zealot]

Does anyone know a working Fast Leaf Decay plugin, because the vanilla tweaks datapack isnt working on folia 1.21.1, correct me if i am wrong

[timid grotto]

pretty sure datapack functions just dont work on folia

[jaunty cliff]

Exact thing is currently happening for us as well

Alongside weird region crashes like this ^

[viral stone]

that doesn't look like a crash as such

[jaunty cliff]

or timeouts *

sorry

[viral stone]

that looks like you have a metric ton of entities somewhere

[jaunty cliff]

yea, but I'm unsure as to why it'd suddenly stop responding vs a gradual TPS drop in that region prior (maybe we just haven't caught it?) & we should be limiting drops per chunk

should be noted that the region starts responding when all dropped items are manually killed

[viral stone]

There is no built in drop limit per chunk

[jaunty cliff]

I meant within our plugins, so it's unexpected behaviour in our environment

[viral stone]

and most issues relating to item entities is people having mechanisms which end up piling entities of some variation into chunks which aren't fully loaded, which then stalls out whenever somebody then causes that chunk to become an entity ticking chunk

so, traditional entity limiting plugins will often fail there as upstream doesn't expose those concepts

[jaunty cliff]

is there any way to properly handle situations like this atm?

[viral stone]

Every solution is an opionated mess

[jaunty cliff]

willing to try anything so these regions stop timing out

[viral stone]

well, the built in save limits only apply to de/serialisation of chunks

I'd listen to the entity load event and limit the entities inside of a chunk that can be loaded

might need to utilise the scheduler to get onto the next tick to safely mess with the loaded entity list for a chunk though, don't remember how that was handled

[jaunty cliff]

i'll look into it, thank you

[real flame]

hello, i have a server that players usually sit at spawn for afk and hanging out, probally around 80-100 players in radius of 100 blocks, and it keep getting crash cause a region in spawn failed to tick, sometimes its another region outside of spawn, is theres any solutions ?

net.minecraft.ReportedException: Exception ticking world```

[viral stone]

That just says an exception occured

you cut out all of the actual relevant information in ther

[fair merlin]

Post the entire log, as cat said. You've cut off the useful information.

[real flame]

ok sorry, i figure out this is a community and not pprovide support for offline-mode server

but can i ask one question tho

if my server get around 100 regions

[fair merlin]

Oh. Yes, we do not support offline mode.

Sorry.

[real flame]

how much core do i need

[fair merlin]

There's no math for that.

But we don't support offline mode servers, sorry.

[elder nest]

Sorry, but how to download folia

I can't use /folia-dl

[fair merlin]

You have to compile it yourself. There are no downloadable builds.

[elder nest]

How to compile

And can i compile using github actions?

[arctic tapir]

sure

see papers readme

[twin spindle]

Hi guys, AMD Ryzen 5 3600X in dedicated server is better "just virtual cpu"?

[lofty magnet]

it's better than not knowing what you have, but not better what you might get

[tawdry gull]

⚠️ Please do not share any links to builds of Folia at this time. We are intentionally not providing easy to find/obtain downloads right now - when the time is right, everything will be available through official PaperMC distributions.

[leaden folio]

hmmm, interessing

[fair merlin]

If you want to use it, you have to build it yourself.

[modest ore]

is that recommended to have folia for very small servers (like 4 players max) ?

Like to be used on huge velocity platform

[little sable]

No, you can use Paper

[modest ore]

ok so for small servers, paper is better? ok fine

[dawn marsh]

does folia takes longer than paper to update to 1.21.3?

[finite hinge]

Folia can't even start until Paper is done

[dawn marsh]

oohhh

i see

[prime juniper]

isn’t folia not even on 1.21 yet

[dawn marsh]

it is in 1.21.1

[prime juniper]

really? inst that a dev branch?

[prime juniper]

yeah but that branch says dev/ instead of ver/ like the the others im confused

[dawn marsh]

dev is like in development stage but you can compile it but it has quite bugs

[prime juniper]

yeah that’s what i mean that a heavily bugged version

[dawn marsh]

i am gonna try now and i will update you

[prime juniper]

Does it make sense to use folia instead of paper on an SMP on a server that has poor single thread performance but a ton of cores (server cpu) even if the player number isn’t extremely big?

[dawn marsh]

i like folia cuz it gives around 100 fps+

[prime juniper]

what?

wdym fps

[dawn marsh]

frames per sec

[viral stone]

It depends on the player spread, and if you're willing to deal with 90% of your common plugins not working

[dawn marsh]

and TPS also

[finite hinge]

If your low number of players all play in the same area it'll just be slower than Paper

If they all live thousands of blocks from each other it might be better

[prime juniper]

im willing to deal with unsupported plugins for performance

[finite hinge]

Usually servers with low player counts stick together though

[prime juniper]

well they would since its with claims and random tp

[prime juniper]

most plugins i use already support folia tho or are working on support

[real flame]

hello, is netty thread have something to do with folia, and can someone explain what is the best netty-thread settings for most case

[viral stone]

No, that's the number of threads dedicated to the netty pipeline

if there was a magical setting it wouldn't be exposed as a config option

The scattering of folia documentation generally has some advice on that last I knew

[real flame]

if setting netty-thread to higher number, like equal to the cpu core the server have, or even double it, is it gonna do something to the server, like lower player's ping ?

[viral stone]

unless you're having contention issues, no

[real flame]

anyone know how to fix this, i want to join a server and it keep showing this

[daring nimbus]

Is that an 1.21 client?

Something sent an invalid packet. Would be interesting ti know if its the server kicking you, or your client disconnecting. If its your client there should be a button below that on 1.21 that shows you more info

[dawn marsh]

yo i am unable to clone folia 1.21.1 using the web URL

[viral stone]

No idea what you mean by that

you clone the github repo and then checkout that branch

[prime juniper]

How’d it go?

[dawn marsh]

i was able to clone 1.20.6 and it was pretty good

[prime juniper]

I thought you used 1.21.1

[prime juniper]

Btw

U use git clone (url) -b dev/1.21.1

[dawn marsh]

will try now

[prime juniper]

or just git clone url and then inside the dir git checkout dev/1.21.1

[dawn marsh]

it worked i am cloning it

[dawn marsh]

What does this mean?

[swift night]

did u compile it correctly

[prime juniper]

gradlew applyPatches

gradlew createPaperClipJar

[dawn marsh]

yes

[prime juniper]

Use this command

@dawn marsh

[dawn marsh]

ok

[dawn marsh]

Nope still same presists

i even agained cloned

the whole file

[little sable]

gradlew createMojmapPaperclipJar

[arctic tapir]

you’re using the wrong jar

wrong directory

[dawn marsh]

it worked thanks

[prime juniper]

[twin spindle]

https://spark.lucko.me/2kJrpf8oMw what wrong with ZGC?

[fair merlin]

No data in this report. You’d have to re-send

[twin spindle]

https://spark.lucko.me/02Pcs40OK4

[winged torrent]

What are those useless Flags? also why so much Ram? Suggest to use normal Aikar's Flags and maybe use 16GB of Ram. Also Folia is still experimental and running on a Ryzen 5 3600X doesn't sound like the best idea for Folia.

[lofty magnet]

the 3600X is a pretty good CPU for it's age though 👀

(but I agree: most likely not worth it running folia on it)

[livid crag]

All those JVM flags and you missed the 2nd half of -XX:+UseZGC -XX:+ZGenerational -.- remove everything and keep those

-Xms32768M -Xmx32768M -XX:+UseZGC -XX:+ZGenerational @twin spindle all you need. nothing else if you just wanna use generational zgc

[twin spindle]

thanks, I understood

[jolly ember]

Hey paper 1.12.1 won't launch anymore

[royal swallow]

#paper-help, also: unsupported version.

[jolly ember]

Oops sorry

Wrong channel

[daring nimbus]

might be alright? not the fastest CPU for sure

I would worry a bit about that connection, 300mbps really is not a lot

[lofty magnet]

OVH's cheap servers really have a low bandwidth :S

[twin spindle]

I don't really need more bandwidth now

[lofty magnet]

why do you need folia then if you have such a low player count?

[twin spindle]

because this more stable for me

[daring nimbus]

Folia is anything but stable

[chrome loom]

^^

Fun graph of my logs over time

24.7M WARN messages from folia

[twin spindle]

so for folia is not bad cpu?

[late flax]

So 16 cores is ideal for folia… my server has 12 cores split between 2 cpus, will folia slow the server down?

[fair merlin]

Probably not a good setup for Folia. NUMA is unsupported so you don’t want multiple CPUs

[late flax]

Disappointing

😂

[finite hinge]

I don't think anyone has ever actually tested NUMA to see how much it hurts

[late flax]

I might text it then

[finite hinge]

We're pretty sure it'll have a performance cost just because it does in general, aside from the memory latency issues multiple CPU sockets and NUMA means locking overhead will be much higher

So presumably your per-region performance will be lower

Is that 5% lower? 20%? 50%? No idea

It probably will run though, shouldn't have to worry about that

[late flax]

I’ll have to figure out how to set folia up

I’m just getting into this stuff

First time on Ubuntu server as well… it has been quite the learning curve

[finite hinge]

If you just have a multi-socket machine sitting around some testing of per-region performance with only one socket enabled and with all of them to get comparisons could be useful

But since multi-socket setups usually have the slowest single core performance CPUs in them taking an extra performance hit doesn't sound appealing

[late flax]

Okay, I’ll try it and report my findings

If I need any help I’ll probably be back.

I’ve been trying to set it up on a vm on my home computer first. Just for the ease of rolling it back if I screw something up

Need longer Ethernet cable for this server and then I should have it up and running

[thick yoke]

Actually this would be a fun experiement

I have some multi socket servers in my basement that havent been turned on in a few years. One of these days I might do some Folia tests with multisocket

If I recall though, there has been a multisocket test of Folia. I just dont think the A/B tested it

[fair merlin]

Feel free to tinker, but especially at larger counts and memory amounts it's not going to be something the average person wants to mess with.

We did a test with a dual CPU mobo but we disabled one of the CPUs.

Not sure if anyone else did one.

But especially at a lower power/core count CPU it's not likely not terribly useful data for most people.

[thick yoke]

Im thinking of the one done on the dual EPYC system with the 2TB of RAM

[chrome loom]

innovation may be happening

[fair merlin]

Yes, that's the one where we disabled one of the CPUs.

[thick yoke]

ah I guess I missed the part about disabling a CPU

[fair merlin]

It's in the pins in here.

Was our first public test, really.

[fair merlin]

Not sure what this is in reference to though

[chrome loom]

people testing NUMA

[fair merlin]

It's not likely to be something supported just due to the nature of how Java/Minecraft handles that stuff.

So nothing to get excited about.

[thick yoke]

It would still be somewhat interesting to see how well it scales

[chrome loom]

i still find it nice to watch people test things ¯_(ツ)_/¯

[thick yoke]

I could do 1P, 2P, and 4P scaling one day

may or may not be worth the effort, but still interesting

[chrome loom]

I run folia in prod, it’s hard enough to take care of day to day. I don’t wanna stray too far off the beaten path atm.

[thick yoke]

I've played with it and that's about it. I mostly stopped after realizing how far away plugin support is. It would take significant work for me to use it in prod, but its still fun to play with and really cool

[fair merlin]

Folia has plugin support. It just doesn't support plugins that want to do things like global state.

So some stuff needs to be re-written and/or re-thought.

[thick yoke]

Sorry let me rephrase, the plugins I need dont support Folia at the moment

[hexed palm]

where do you find this cheap servers omg

[twin spindle]

this is bad?

[hexed palm]

not that much, for my use It will be great.
Lot of ram, lot of cores, perfect for hubs servers!

the bandwith can become a problem, unless I use compression

Oh fuck, only NA

[twin spindle]

yes

[hexed palm]

It was a good deal to switch from my RISE Game1 (3600x i think)

[twin spindle]

so for folia is great better epyc?

speed of ram is 2400mhz

[hexed palm]

will be great to have a better clock

[twin spindle]

here

[hexed palm]

Where country is your community based?

[twin spindle]

EU

[hexed palm]

Which country?

All the EU?

[twin spindle]

UA, BY, KZ, RU, small from EU

but before for buying dedicated server I need verificate my account I guess

[hexed palm]

Germany, Finland or Poland will be the best I think

[twin spindle]

you can please help me with ovh?

[hexed palm]

for what?

there is also this hosting provider: https://www.hetzner.com/dedicated-rootserver/?pk_source=google&pk_medium=cpc&gad_source=1&gclid=Cj0KCQjw1Yy5BhD-ARIsAI0RbXYyrvci-UBIrjMFqYseE-Edd3943KYr56aOY-f_7Ocs9xISz345_6AaAt8kEALw_wcB

[twin spindle]

for buy

[twin spindle]

hetzner deactivated my account, so I don't wanna any deal with us

[hexed palm]

its pretty simple, just create an account, then select the server you want, then buy it with paypal or cc

there is also this one: https://contabo.com/en/dedicated-servers/

[twin spindle]

but I from ukraine and ovh can decline my deal

[hexed palm]

I dont think they will decline it!

[twin spindle]

I get declined in past when I buy my first vps in ovh

[hexed palm]

for which reason? pretty weird

[twin spindle]

so I'm afraid of it

[twin spindle]

for payment method or what

[hexed palm]

do you have a paypal account?

[twin spindle]

yes

[hexed palm]

and got declined with your pp account?

[twin spindle]

in past yes

[hexed palm]

wtf

[livid crag]

This is not a place to recruit member to bypass CYA process of any company or tax evasion @twin spindle

Please do not do that here in the future

[keen rose]

does folia have world loding, or something that can load multiple different worlds like multiverse?

[fair merlin]

Don't think Multiverse works for Folia right now.

[finite hinge]

There is a plugin library thing that sort of works to load worlds at runtime, if you are careful about when you do it, but there is no supported way to load worlds and no way at all to unload worlds

[real flame]

hey uh, general question cause i dont really know what does grid-exponent and threads actually do in this config

[spice citrus]

how can I optimize folia? while preserving mostly vanilla?

[tawdry gull]

Community contributed configuration guide for Paper: https://paper-chan.moe/paper-optimization

[inner swift]

The guide still applies

[little sable]

Send a spark report

[spice citrus]

I'll take a look at the guide

[tawdry gull]

🚨 Offline Mode

It appears that you are running an offline-mode server.
We, as a community, do not provide support for setups that bypass Mojang's authentication. You are on your own to solve any issues that arise.

[spice citrus]

Heh. Isn't velocity require offline mode backend server?

[little sable]

You use SkinRestorer

[arctic tapir]

the backends require it to be offline

the proxy needs it to be true

[spice citrus]

it is true

# Config version. Do not change this
config-version = "2.7"

# What port should the proxy be bound to? By default, we'll bind to all addresses on port 25565.
bind = "0.0.0.0:25565"

# What should be the MOTD? This gets displayed when the player adds your server to
# their server list. Only MiniMessage format is accepted.
motd = "<#09add3>A Velocity Server"

# What should we display for the maximum number of players? (Velocity does not support a cap
# on the number of players online.)
show-max-players = 150

# Should we authenticate players with Mojang? By default, this is on.
online-mode = true

``` ^ here right?

[obtuse basin]

yes

[viral stone]

Your server is not setup for velocity properly

that spark profile was created with an offline mode account

if your proxy actually was in online mode, you forgot to setup forwarding; and now all your player data is effectively doomed unless you can convert it

[spice citrus]

O man. I need to recheck thanks

[little sable]

And you can delete SkinRestorer

In the project our dev version of Folia 1.21.1 is not found although we have followed the steps on your github this error code comes up all the time.

Could not find artifact dev.folia:folia-api:pom:1.21.1-R0.1-SNAPSHOT in papermc (https://repo.papermc.io/repository/maven-public/)

Are there any ways that you could still use them in the project?

[arctic tapir]

publish it to your maven local

what is better?

[livid crag]

There is no “better”

Pick a value that’s most suitable for your player count and hardware

Using spark report to see how your server is doing

Also your animal spawn is way too fast. Default is 400. Idk why you make it 30.

[tranquil raven]

If i want to use the registerNewTeam method from the Scoreboard class, but then it cause following error. I'm currently using the paper-spigot dependency, to get this working on folia? 🙂

[daring nimbus]

Scoreboard doesn't exist on Folia

[tranquil raven]

oh okay

[daring nimbus]

relies on a global state that doesn't exist. If you want to use it to display stuff (sidebar, displaynames), you have to use packets

[tranquil raven]

Allrigth, thank u 😄

[lavish peak]

if you use velocity you could use velocity scoreboard api lib

[tranquil raven]

We have loaded a plugin and for some reason this error message comes up on our dev server nothing has happened except now on this server.
We currently have no idea how to solve it

[fierce knot]

I don't think you can TP a player on the PlayerJoinEvent, delay it by a tick

[raven mesa]

Does the Spark profiler normaly work with Folia?
I get the following Problem:

[11:52:48 INFO]: [spark] This server bundles the spark profiler. For more information please visit https://docs.papermc.io/paper/profiling
[11:52:51 INFO]: [spark] The spark plugin has been preferred but was not loaded. The bundled spark profiler will enabled instead.
[11:52:51 INFO]: [spark] The spark profiler will not be enabled because it is currently disabled in the configuration.

But i couldnt find any configuration that would disable the profiler ... the only setting i found was laying inside the paper-global.yml and there it is activated:

spark:
enable-immediately: true
enabled: true

Or if spark currently doesnt work can you guys suggest any other monitoring plugin working with Folia?

[livid crag]

You will need to grab the Folia branch of spark.

[raven mesa]

thanks 🙂

[raven mesa]

is a report like this also created with Spark? If so, how can i see this? Its pretty hard to find something about monitoring with Folia 😄

[viral stone]

That's the folia tps command iirc

there is a spark branch for folia

but, realtime monitoring of any game is pretty hard, especially if you wanna collect useful metrics

[prime juniper]

Unfortunately, using folia doesn't solve anyone's problems, and most people here don't need an environment like folia, if you really need any high-performance (if you don't need any vanilla features), it makes more sense to use solutions like minestom because when using folia, you have to write most plugins yourself or use broken forks

[daring nimbus]

except that Minestom has zero vanilla features

Most people actually want a server that does more than just being able to connect to

[prime juniper]

I think the folia mismarketed it here, when people saw that they could handle 1000 players on the same server at once, they started to use this fork in nonsense server types

[inner swift]

https://papermc.io/software/folia/
Folia won't be useful for the majority of servers out there and will break most public plugins. It's ideal for servers with very high players counts, that offer gamemodes that naturally spread players out, such as SkyBlock or SMP.
The marketing seems to address this?

[prime juniper]

To create a functional playable server with folia, it is necessary to rewrite a lot of plugins, and we also have to use packets because the api is broken, I think someone who uses folia for simple things can already create a server with minestom

[daring nimbus]

I still haven't seen a single public server use Minestom in like five years, lol

Folia on the other hand does actually have all vanilla functionality except for some datapack/command stuff, and plugins are pretty easily adaptated to it (instead of needing to be rewritten from the ground up)

[finite hinge]

minestom is for minigames

[prime juniper]

When it first came out, I saw a lot of news, 1000 players on the server, so and so on, benchmarks were shown, but no one talked about its logic, only thread safe was passed

[daring nimbus]

not sure what your point is

[inner swift]

I think the PaperMC team mismarketed it here
So, third parties, not Paper

[prime juniper]

I mentioned in my previous message that if it doesn't need the vanilla feature

[finite hinge]

If you want little to no vanilla functionality implementing just what you want to begin with using minestom can make more sense than trying to disable/block things

It won't get 1000 players on a single server though

[prime juniper]

Stupid translation sorry

[livid crag]

it breaks the limit of single main thread running most logic. This is covered on the page.

[prime juniper]

I know, but I don't think most of the people asking questions here really need it

[finite hinge]

Folia is for people who want all of the vanilla features (well, not all, but most), have large worlds where people spread out or cluster in small spread out groups, have a ton of players, and have a full time developer to work on the server

That is basically like 10-20 servers in the whole world I think

[livid crag]

Exactly. We already know that. Majority of Minecraft server has 1 player and less according to bstat. but it's ok to ask question

[finite hinge]

Well, the other group that would benefit is people who don't need many/any plugins, only play with a few friends, but each one wants to have their own farms and crap so on a normal server they'd choke it out with entities

It has very narrow uses, I don't think anyone has said otherwise

[prime juniper]

Thread safe is not suitable for vanilla Minecraft in my opinion, it breaks a lot of things and mojang's terrible policies make it harder to develop code, I think a software that supports vanilla features should be made from scratch, but since it's too hard, no one tries it.

[naive fable]

The reason for that is that the people who actually use folia dont ask questions here, they figurenit out themself. People on this server usually dont have answers for the kind of problems those users get

[chrome loom]

for example for us (i run folia in prod full time now) use the multi-threading to allow our more technical players to build really laggy farms that only effect the region that player is in.

while allowing all the other players doing other uses of their time to have good tps

[opaque rose]

don't know why, but is it a bug that the items on the trapdoor go back up after experiencing the flap door opening and closing quickly, and the items that were flowing out go back up again?

just like this

[royal swallow]

Could I benefit with using Folia for my SMP (vanilla styled) with around ~50 players online all time. Right now using paper We had to nerf simulation distance and do a lot of non-vanilla changes.

I think most of the crazy farms players build - so the TPS is good for the others. This is the big reason I see with going with Folia.. the question is If my specs are enough…

This is my specs currently:

https://www.ovhcloud.com/en/bare-metal/rise/rise-game-2/

Or is paper the better alternative? Only plugins we really use is CoreProtect which has Folia support.

[fair merlin]

You're probably better off sticking to Paper and tweaking your configs.

[tawdry gull]

Community contributed configuration guide for Paper: https://paper-chan.moe/paper-optimization

[inner swift]

Your specific case seems like it'd require little dev time to just try and see, if you do try it, please report results

Just, the usual disclaimers apply, there's limited data on setups of this kind for Folia and you're too below the recommended minimums

[chrome loom]

As Kyle said, try it and see. We put the dev time in for it and it worked out pretty well for my server. allows for the players to build crazy machines and it not break down.

Although we are running closer to the recommended specs for folia.

[humble mesa]

We are about to switch our server from paper to folia. We have all of our plugins converted over, and everything is working great. Are there any bugs i should be aware of that we may have missed? Anything to look for in particular?

[livid crag]

You can look at the Folia issue trackers for confirmed bugs; otherwise, if you find any issue, and know how to reproduce it, welcome to open a report.

[humble mesa]

yep, thats the idea

[undone storm]

Hello
Does anyone know any good minecraft server hostings?
I am really excited about Folia's multithread and want to check it, but all hostings that I find offer max 6-8 cores, not 16

[inner swift]

You'd need a dedi, so you're looking at hosts such as Hetzner and OVH

[undone storm]

what is dedi means?

[inner swift]

A deficated server

So, all of the hardware for yourself

Hello guys, does anyone know a good folia fork for smp servers?

[manic quarry]

uh... folia.

[onyx oracle]

hm, okay

[flint wren]

im not sure why but my cpu usage is peaking to 80% sometimes while its chilling at 3 percent most of the time, this causes big lags for the 10 players that are online, 56threads @ 2.4 Ghz and 52gb ram

[tawdry gull]

Please provide a spark report

spark is a profiler bundled in Paper for troubleshooting performance-related issues. Please run /spark profiler start --timeout 300 while the performance issue persists.

After 5 minutes, paste the URL given here so it can be reviewed.

Support will resume when all necessary info is provided.

[flint wren]

spark isnt a valid command for me

[fair merlin]

You have to download the Folia build of Spark.

Look in this channel for where to find it.

[flint wren]

alright thanks

https://spark.lucko.me/Aq3A2Q8XTk

[tepid bronze]

It seems that your GC is doing an awful lot of work. Other than that, everything seems to be perfectly fine. At least I am unable to see anything out of the ordinary

Mind running just /tps? On Folia it has a bit more functionality, like showing the most performance heavy regions

[flint wren]

currently 1 player online and its not lagging anymore as he told me, if a lag happens again ill tell you 🙂

[finite hinge]

You should try ZGC

Or at least Aikar's flags if you stick with G1GC

[fair merlin]

We don't support offline mode servers.

[arctic bear]

🤔

https://github.com/PaperMC/Folia/issues/280 Did anyone meet this bug?

[orchid sluice]

Is folia still worked on?

[fair merlin]

Yes.

[viral coral]

the latest commit is 5 days ago so yes

[fair merlin]

#folia-dev You want

[flint wren]

i got those issues again Region around block [w:'world',1095,80,-649]:
84.1% util at 53.96 MSPT at 15.56 TPS
Chunks: 2,170 Players: 4 Entities: 1,135

[viral stone]

Folia is not designed to be ran in a memory constrained environment

3-4G of ram is pretty much the minimum for vanilla these days, and that only has a small number of threads spewing memory around

[inner swift]

They have the Xmx set to 50GB, the number Spark shows is just the current heap size

[viral stone]

Not letting the jvm just have that means that you’re going to be leaving the JVMs expansion logic to deal with that

It’s better than it was in the past, but, not something I’d recommend for folia at all

[inner swift]

Oh, you're talking about the flags, fair

[tawdry gull]

⚠️ Please do not share any links to builds of Folia at this time. We are intentionally not providing easy to find/obtain downloads right now - when the time is right, everything will be available through official PaperMC distributions.

[flint wren]

So run without flags?

[viral stone]

Xmx == Xms

your thing only has 4G of ram allocated

and it's spending a good chunk of time in the collector, so might be some wider issues

[flint wren]

Xms == Xmx right now should i change that im kinda stupid rn

[viral stone]

I would generally look towards using generational ZGC for folia

[flint wren]

Thate spark above is an old one sorry

Im using aikars flags rn with 30 xms and xmx

every time those lags occur the proxmox cpu usage spikes from 6% to 70-90%

[strong kelp]

ETA on 1.21.3?

[manic quarry]

when ready

[strong kelp]

i see

[obtuse basin]

1.21.1 isnt even merged yet

[fair merlin]

Even more than Paper, Folia doesn't have ETAs for things.

It's generally a "when Leaf gets the time" kinda thing.

[granite quartz]

why folia is 1.20.6 and not 1.21.1

i really need it

when it will be updated

[fair merlin]

There's a 1.21.1 branch.

[granite quartz]

how i get it

for the 1.21.1

[fair merlin]

It's in the repository, just like the other branches.

You have to build Folia yourself.

[granite quartz]

but it is possible to build 1.21.1 then?

[fair merlin]

If you can't build Folia you probably shouldn't be using it, because building it is going to be the least of your issues.

[granite quartz]

i know how to build

it

C:\Users\jxstc\Desktop\server>java -jar server.jar
Error: Unable to initialize main class org.bukkit.craftbukkit.Main
Caused by: java.lang.NoClassDefFoundError: joptsimple/OptionException

this error is ouccuring

[viral stone]

you likely grabbed the wrong jar

build it as per the paper readme

[granite quartz]

this read me?

[tacit tartan]

Cat said the paper readme

[granite quartz]

Okay

so this here

[viral stone]

yes

[granite quartz]

thank you i'll try it

it works

but how i can make my plugin compatible?

[livid crag]

The developer needs to make modification to have it work with Folia. It’s not something you can do if you have zero Java knowledge.

Sounds like you should stick to using Paper, Folia is for advanced user only @granite quartz

[granite quartz]

i have java knowledge

i'm coding since i'am 9 years old

[viral stone]

it's covered in the general smattering of documentation around

your plugin needs to have the folia token thingy inside of the plugin def file, and then you also need to make sure that you follow the "laws" of folia

[granite quartz]

i cant click on it

[viral stone]

yes, that is empty

[tawdry gull]

Folia

Folia is a fork of Paper that adds multi-threaded region support. Many plugins will require updating to support Folia. There is no ETA for publicly available builds.

For more information:

• Readme
• FAQ
• Regionising logic
• Detailed overview
• Javadocs

Folia will:

• NOT be backported to older versions <1.19.4
• NOT be merged into Paper
• NOT be ported to Fabric nor Forge

Stay tuned to #announcements for any further info about releases.

'ETA' means 'Estimated Time of Arrival'!

[viral stone]

see the info in those links, etc

[granite quartz]

where i can find general smattering

[granite quartz]

hmh, folia token ? plugin def? you mean plugin.yml?

[viral stone]

yes

[granite quartz]

and i can use paper api?

or folia api

what is the difference

[viral stone]

paper supports all of the folia API

[granite quartz]

that means?

and bukkit api?

[viral stone]

The folia API needed to be able to play by the rules of folia exist within paper

there are some api breakages when using folia

[granite quartz]

what do i have to do to make my plugin support folia?

[viral stone]

depends on your plugins

read the readme

[granite quartz]

which readme? folia or paper

[viral stone]

folia

[granite quartz]

wait

i read it but how i can implement it now in my plugin :c

[viral stone]

I can't really help on that front

it is once again going to be 100% down to the plugin

you need to adjust the plugin to ensure that it works in a multithreaded environment

and follows the rules of folias regioning logic, i.e. ensuring that any world access is 'safe'

[granite quartz]

do you have any documentation?

[viral stone]

not really, all of that is once again covered in the scattering of readme things around the place

This is pre-release quality software

[dire pebble]

The Docs of it are like the regions shattered, a bad joke in my ears.

[granite quartz]

do i just have to use "folia-supported: true" in my plugin.yml?

[fair merlin]

No.

You need to make sure it works in a multithreded environment, as cat said.

Search the pins in this channel and the various bits of documentation

[granite quartz]

okay

does anyone have a tutorial for it?

[livid crag]

Not really. This is basically your Java knowledge

[timid grotto]

there is no "just make these changes" type of tutorial you could follow for something like this

you have to actually understand what threading means for your plugin

[granite quartz]

i have java knowledge but i dont understand what exacly this means for my plugin and how i can make it support folia

[viral stone]

Once again, there is no magical guide of how to migrate a plugin to supporting folia

We cannot see your plugin

We cannot tell you the scope of changes you'd need to make

The general rules of engagement are in the readme, outside of that, its on you to figure out how you need to adopt your plugin to run inside of those rules

[granite quartz]

do i have to add classes like Scheduler for folia?

[viral stone]

you don't have to add any classes

you'd just want to use the folia scheduler as the bukkit one will not be accessible to you

[granite quartz]

but how i can use it

for example

[viral stone]

the exact same as the older schedulers, only it requires you to specify where in the world you want it to run

[granite quartz]

okay

but does i have to use it with the folia api or with the paper api?

[viral stone]

.

[granite quartz]

hmm okayy i understand, works it as the same? (bukkit / paper / folia) like the main class etc.?

and i just can implement it into my plugin yml

[viral stone]

plugins are still loaded as plugins

[granite quartz]

okay

[granite quartz]

do you know whats happened to the /save-all command?

in folia

i understood the api a little bit

i have made my first folia supported plugin omg

[tacit tartan]

a bunch of commands are removed / not yet implemented on Folia, there's a list on the docs somewhere.

[manic quarry]

you generally should not have a use for that command, and for folia especially lol

[strong kelp]

use the dev branch on the github

also its pretty stable i havent run into any errors yet

[granite quartz]

how i can save my world then

[manic quarry]

It saves automatically

[granite quartz]

even when the server crashs?

[manic quarry]

it saves constantly

every tick x amount of chunks is saved

by default it's 24 iirc

paper doesn't have the entire "saving full world in one go" thing for years now

cause, surprise, that stops the server for the time it takes to save

[chrome loom]

The goal is for it not to crash

[granite quartz]

when does folia will become stable?

[livid crag]

It is by all means stable

Big network like 2b2t and DonutSMP has been using them for over a year at this point. You just require a dev team to adept what you do to Folia.

[strong kelp]

yeah

even with dev versions

it seems stable enough

the only drawback is the lack of scoreboarding and other features

though some plugins can just use their own API as a workaround like tab

[void agate]

I have a question: is it a good idea to use Folia on a production server now?

[strong kelp]

depends on the size of the server

[void agate]

100+ players

[strong kelp]

is the map spread out?

[void agate]

yes

[strong kelp]

yea then if you have that much and the map is that big, go for it

[void agate]

Oke but folia is still in beta and the compatibility with plugins is not that good yet ?

[finite hinge]

Compatibility with plugins will never be that good

Unless plugins rewrite for Folia

If plugins are written for Folia they work on Paper so in theory most could some day be compatible but that's up to plugins, not Folia

[void agate]

okay thanks

Are you building this in Linux or Windows?

I just grabbed a fresh copy of the repo and built it just fine.

I'm on Debian 12.

java version "21.0.5" 2024-10-15 LTS Java(TM) SE Runtime Environment (build 21.0.5+9-LTS-239)

So it seems like something with your system or Java install is breaking it.

Best suggestion is to run make sure the Java install is working properly, and run through the build steps on the Paper repo to make sure you aren't missing something.

[calm fable]

linux

i mean it is working properly cuz the actual server is running on it

let me setup a "build" system

getting that every time a seed is used where spawn is water

err rather 0 0 is water

the server locks up and never initializes world. the server remains unjoinable tps shows spawn chunks utilizing 100 percent of core

2217231467331653763 example seed that does this

[fair merlin]

We tested this and confirmed it was an issue using the seed you provided. Leaf pushed a fix, which we re-tested with the same seed and confirmed it loads now.

Hopefully that fixes your issue.

[calm fable]

sweeet thanks so much!

[ornate warren]

Hi, we're speccing up a custom plugin for a new Folia-based server we are planning. It's going to be managing a lot of real-time data of players riding horses (blocks traveled while riding), as well as the horse data itself (blocks traveled with rider, speed, location and other stats) - where we previously just utilised an sqlite db for something similar on a Paper server, would we be better to start with a different db type (MySQL, MariaDB, MongoDB) for a Folia implementation? (or maybe even using Redis for live caching with intermittent writing of relevant data to another db for persistent storage?)

[manic quarry]

you can just stick with sqlite if you don't have any issues with it

if you set journal mode to WAL you can even save to it from multiple threads

[ornate warren]

Oh cool, thanks for the info 👍

[finite hinge]

iirc you have to compile sqlite with a non-standard flag to get multithreading support

Which has a performance cost even if you don't use it so I'm not sure if the standard Java JNI packages do it

WAL is generally what you want and makes it possible for multiple processes to work with it but apparently multiple threads is a different issue

Oh it looks like the default compile flags actually leave it open to enable the other options, I thought it defaulted to single threaded which blocks the ability to change it but it defaults to serialized

https://www.sqlite.org/threadsafe.html

[manic quarry]

it used to work like you say, it changed tho

sqlite is pretty much as good as any standalone sql server nowadays

which is actually insane if you think about it

there's also a fork of sqlite called libSQL that is working towards having a database per user model

[calm fable]

that would be cool if we could get redis support into folia

for a central memory store or somethign

[bold osprey]

that's really really far away from how folia works

[finite hinge]

Central anything is kind of missing the point 😄

[calm fable]

but there are now and will be in the future plugins and such that depend on shared ram

[finite hinge]

You should be designing things to need less centralized sources of data

[viral stone]

Folia doesn't need redis support

[calm fable]

right redis is distributed 😄

[viral stone]

No?

It's an external data store intended to be a central point for accessing stuff remotely

[finite hinge]

No no I mean your plugin shouldn't have too much concern about the performance of concurrent data structures or locking because you shouldn't need many global data stores

[viral stone]

it might support things like sharding, but that's for HA and large scale deployments, something which is pretty much irrelevant to most block game servers

[finite hinge]

It should all be things that are localized to a player or area

[viral stone]

redis solves nothing for folia

and for plugins, if they want redis, they can do that themselves

[calm fable]

pardon my let me speak more clearly, you can distribute data on multiple redis servers so it can act as a distributed store

[viral stone]

Which is irrelevant to folia

How your external data store can manage data stored elsewhere is irrelevant

[calm fable]

the reason i mention it at all is many plugin dev's i have spoken with about possibly getting a folia port, have mentioned this issue as theres no place a mod withing folia can go to keep data in ram

where more than 1 plugin interact*

[viral stone]

nothing in terms of plugin interactivety changes here

[calm fable]

im not a dev so its possible i misunderstood what they were saying

[viral stone]

and folia supporting redis is literally 100% irrelevant

that would be on the plugins to support that

[calm fable]

fair enough

[viral stone]

like, even if folia bundled the redis client, you'd still need to setup a redis server elsewhere, and you'd still need plugins to integrate with redis

[calm fable]

well

for the sake of a for instance if you will indulge me

couldnt folia itself write that data to redis directly via api for plugins?

[viral stone]

what data?

plugins aren't storing their runtime data inside of the API, they're storing it in generic java collections, like hashmaps

[calm fable]

yes that makes sense

i guess maybe it wasnt explained properly why its difficult to make plugins for folia

[viral stone]

Folia requires that plugins support working in a multithreaded environment

This is a concern because most devs within the ecosystem have generally not had too much experience with threading, but, also, because converting a codebase from running in a primarily single-threaded environment into one that your entry points can be called concurrently is often non-trivial

accessing world state is also more complex, because now you have to get into the correct 'context' to do that

[bold osprey]

And sometimes it's a lot easier to just write an alternative/complete rewrite than changing so much to adapt the plugin

[calm fable]

so the plugin has to designed such that any information u stored is kinda stateless? am i understanding that right?

[viral stone]

No?

Plugins need to be designed in a manner that any information they store is accessible in the manner that they need it

but, that is more going to tilt towards ensuring that their own data is thread safe

[calm fable]

sorry for any delays im googling a lot right now hah

ok now this is making more sense, thread-safe was the keyword there

so yesterday i uncovered a deadlock bug in starting folia on a world in specific seeds where 0, 0 is water and there no spawnable locations within 32 blocks. that "32" was changed to 1024 i believe. id be interested to find out what causes the deadlock in that scenario

[viral stone]

loading chunks on the region threads often blows up in weird manners

the game tries to look for a specific biome for you, and will go searching for it

[calm fable]

right but why would that lock up the spawn chunks indefinitely?

[viral stone]

Because the thing needs to go look for a valid spawn biome, etc, and that is not with a player standing in a puddle unless it fails

The thing failed here because the needed chunks weren't already loaded, and the thing stalled out because it couldn't go and get the chunk

[calm fable]

ahhh

ok

[viral stone]

The fix here was to basically ensure that the chunks are loaded in some for it to be able to do stuff

[spice helm]

Why people even use folia

Not useable with 99% of plugins

[viral stone]

Because if you have the resources for it then it makes a lot of sense for a niche set of usecases

[spice helm]

Like paper is 100% time better

[viral stone]

until you want to handle a few hundred players on an instance, sure

[spice helm]

Oh

[haughty gale]

nuh uh

[fair merlin]

Paper is faster if you're using a crappy CPU.

Or like a tiny VM.

[chrome loom]

paper is better general purpose

[spice helm]

My machine that im running on it is 32gb ram 16cpu Ryzen 9 (its 128gb 64cpu but im hosting a whole things oj it

[sullen temple]

Tbf folia / multi-paper only applies to survival based gamemodes

You can hold up to 1k players on prison on latest versions which is surprising in itself

[young burrow]

2 words:

Coordinate Exploit

theres a bot on my server in a hole in the ground holding a sword swatting in 1 direction for a bit then turning around and doing it another direction

coordinates of peoples bases being spammed in my discord

[fair merlin]

Are you saying this is an exploit in the current build of Folia?

[young burrow]

nah dev

1.21.1

idk how to figure out what they are doing

[fair merlin]

Can you open a report in the exploit report channel along with a bunch of info including logs?

[young burrow]

yeah

[mild temple]

does folia support world-generation datapacks like terralith?

[inner swift]

I'd say try it and see™️, I'd expect the worldgen part to work, but I'm unsure whether Terralith has non-world gen related parts. These would not work

[mild temple]

alright i'll try, thanks

[chrome loom]

It does work

why do some mods not work on paperclip jar, but do work on mojangmapped ones? whats the difference?

[lofty magnet]

well one is mapped with mojang mappings the other isn't

[calm fable]

what does that mean though? if you dont mind answering 😄

[lofty magnet]

which part of my statement? also are you asking about Folia or in general?

[calm fable]

well folia because theres a plugin called fancynpc's which we use. using the create paperclip jar command on gradlew creates the folia jar but the plugin screams about issues. i talked to the devs of the plugin that said we have to use the create mojang mapped jar , so i did and it worked. i guess im asking whats missing from paperclip?

[lofty magnet]

ah yes, folia is mojang mapped by default

as there is no reason to try to be compatible with plugins using spigot mapped nms as it breaks anyways

your only chance is using plugins made especially for folia or some that only use Bukkit API that isn't broken by folia, other plugins are unlikely to work without issues

[calm fable]

thats what fancynpc's is

its bukkit but folia compatible

[lofty magnet]

then it shouldn't have any issues with mapping

[calm fable]

somehow it still needed the mojang mapped folia jar

[lofty magnet]

the fact that they have mapping issues means that they are using internal stuff that isn't part of the Bukkit API

[calm fable]

oh im sorry i said something wrong, it doesnt use bukkit it uses paper

api

[lofty magnet]

(and seeing as it's an NPC plugin and you can't do NPCs with just the API that's a given)

[calm fable]

[16:04:45 INFO]: Paper Plugins:
[16:04:45 INFO]:  - FancyNpcs
[16:04:45 INFO]: Bukkit Plugins:
[16:04:45 INFO]:  - ArmorStandEditor, AxGraves, BBeeChecker, BlueMap, Chunky, ChunkyBorder, CoreProtect, Craftorithm, DiscordSRV, GSit
[16:04:45 INFO]:  InstantRestock, LuckPerms, PlayerDoll, SuperExpress, TabList, voicechat

so its using some other paper specific api i assume

[lofty magnet]

doesn't make a difference, there is no API to do what the plugin does

[calm fable]

oh i see

[lofty magnet]

they are using server internals which they need to adjust to be compatible with folia

[calm fable]

now i understand thanks, they are manipulating the mojang's code so they need mojang's mapping to be in place

[silver sierra]

you should never use createReobfBundler/Paperclip in production on 1.20.5+

always use the mojmap one, the reobf one only exists still because it can be useful for us to debug things

[high quest]

hey sry for a little stupid question I mean a really stupid question, Okay so I want to make an SMP with 200+ Players on a Cloud based Network on a Dedicated Server with 16 Cores ig and just want to know if it really worth it to use Folia instead of forks like Purpur?

[fair merlin]

Focus on getting players and then expand as necessary. No one is going to have 200 players on day 1.

It would be difficult to have 200 players on a single Paper server unless you aggressively customize it and nerf gameplay. If you’re going for a vanilla-like experience it’s very difficult.

But Folia is resource intensive so you generally need a dedicated server.

And plugin support for Folia is limited.

Can’t really speak to forks of Paper because it isn’t our software. Generally if you aren’t sure if you should use a fork, you’re better off sticking with Paper.

[high quest]

Okay thx

That info helped me a lot

[bleak vortex]

hello! can you help me, how i can resize region ? now i tested, 2500x2500

what does the grid-exponent mean?

[bleak vortex]

i going stress-test, players join and random teleport to 1000-10000 coords, and i have this :

how i can fix that?

r9 7950x + 128gb ddr5 +nvme

[manic quarry]

well, one of the regions has something going on

teleport there and locate the issue

did you mess with resizing regions?

did you change anything you did not understand

[hexed ice]

your players are not spread out enough for it to put them in seperate regions, everybody's in the same one

[bleak vortex]

but these players are at random points, how can I reduce the size of the region, they were at different points?

[hexed ice]

you can't do much to reduce the size of regions, rather you should increase the distance between players

[bleak vortex]

how i can do this

[bleak vortex]

how i can reduce the size of regions,
or is it impossible?

[bleak vortex]

according to the data, they are located at a distance from 500 to 1500 blocks, it’s just strange that first the kernel scatters them to different regions, then combines them into one and lags

[manic quarry]

the logic only works when the regions are separated from each other

otherwise you're just making things actively worse

think at minimum 2k blocks

there needs to be absolutely no possibility of 2 regions "colliding"

if there is, server will merge them

regions cannot exist close to each other

[bleak vortex]

okay, can you help me with settings for my server at folia?

[manic quarry]

golden rule of configs

if you don't understand what it does, don't change it

reset everythingg to default if you're not sure

[bleak vortex]

I generally understand what I’m setting up, but the problem is that I want to see a smoother TPS during such stress tests.

Can a world that is not preloaded drop TPS so much?

[manic quarry]

chunk generation has little to do with tps

[viral stone]

increasing the number of threads is going to do nothing when you've grouped your players too close together that they're all in a super region

at this point you need to get players to spread out, otherwise you'd be better off just using paper

[bleak vortex]

and at what minimum distance should they be separated?

This is strange just at server-wide events where about 300 people will gather.

[viral stone]

.'

[livid crag]

Unless those 300 players will never meet at any given point of your event and will always be 2000+ blocks apart from each other, Folia doesnt seem to be an ideal solution for an event.

[smoky owl]

Hi! We have server with like 250-300 players and we are considering switching to folia. Now we have very optimized and limited version of Paper (for our specification we don't need monsters etc), but our machine only has 8 3.6 GHz cores (I can send more specs later). On folia docs it is recommended to have at least 16. So will folia even help on our machine? Do you maybe have some benchmarks?

[fair merlin]

Folia wants more cores because it's breaking up into regions, and it's going to run a thread for each of those regions. You'll be able to get away with more if you have no monsters but if you have no monsters I'm guessing the players are going to be in a small space which will likely negate the benefits of Folia.

It wants players to be ~2000 blocks from each other. If everyone's in one small area then Paper would be faster.

[marsh zealot]

Hey there, short question to the ChunkUnloadEvent based on player logouts, are there some special rules with Folia, because we have had some issues the past weeks, where items insta-despawned after death and logout of a player. Shouldn't the Chunk get nearly instantly unloaded after a player disconnects out of this chunk?

[hollow grotto]

anyone have compiled version of Folia i can test?

[tawdry gull]

⚠️ Please do not share any links to builds of Folia at this time. We are intentionally not providing easy to find/obtain downloads right now - when the time is right, everything will be available through official PaperMC distributions.

[left swan]

@hollow grotto ^

[smoky owl]

Okay, but on folia website they recommend 16+ cores

Is folia still a better option for servers with 12, 8 cores?

[timid grotto]

but if your players are all grouped up, paper is a better choice, no matter what hardware you have

[smoky owl]

we have very big map

and players live in nation

so I think we can benefit from golia

folia

[timid grotto]

how far apart will players be from eachother

[smoky owl]

Idk, like 1k in europe and like even 5 between continents

[lofty magnet]

in the minecraft world

[smoky owl]

yeah, it's all in one word

[timid grotto]

how far apart are the players in the minecraft world

[smoky owl]

like 1k blocks

so they are like 10-30 players in one place and then like 1k blocks to other group

[timid grotto]

you need players to be farther apart than that to make sure you get multiple regions

[smoky owl]

Okay

But I'm mostly considered about my machine having only 8 cores, while the recommended amount is 16

even if players are far apart

thanksss

[inner swift]

But note that if players groups are at most ~1k blocks apart from each other, you will get one big region. That'll perform slightly worse than Paper

[smoky owl]

ohhhh

[severe hedge]

How much RAM will Folia require? I saw on the 300+ testing server y'all allocated over 500GB. Right now with our Paper server we're allocating 24GB since we're told that anything higher than that will cause memory leaks from the base game

[finite hinge]

The test was just throwing as many resources as possible at it and seeing what happened

afaik it doesn't use much more than Paper with the same user count although since you'll be working to keep players more separated with Folia you'll have more chunks loaded than an average Paper server

[severe hedge]

Oh thank goodness lol

I'm also looking to start developing plugins for Folia. I understand that development on Folia in general has stagnated a little bit, but our 1.21.1 Paper server is crawling out of the pits of hell, struggling to run at 150 players. Is there a getting started guide anywhere for plugin development?

[manic quarry]

generally same as paper, but with a little asterisk - if anything has a global state (ex. scoreboard, a lot of commands), it won't be working

[severe hedge]

As in the API's for it are different or as in it hasn't been implemented at all

[manic quarry]

you will get not implemented errors

you will know.

[severe hedge]

Ah okay

[manic quarry]

and one more thing, scheduler is defunct, use one of the ones paper and folia api provides

[severe hedge]

Tysm

[manic quarry]

so Bukkit.getAsyncScheduler, Bukkit.getRegionScheduler, etc

some things might be kinda awkward, but that's what you get when you're trying to synchronize multiple threads ticking in parallel

[severe hedge]

I'm not stressed about multi-threaded programming, the concept isn't new to me. The API's however...

Normally I work with C# instead of Java

We'll see how it goes.

[manic quarry]

microsoft java™️

you should be fine

[severe hedge]

Makes sense

[storm sun]

When to take action for broken API in folia, Otherwise I will have to use paper

[inner swift]

Is this a question about when Paper will re-add the API or are you asking about actions you have to take to get around the limitations?

[storm sun]

No, just the broken API. When will it be fixed?

[tawdry gull]

__There Is No ETA__

Updates to Paper do not have any sort of estimate for when they release, ever. Any and all updates will arrive when they are ready, and the only thing to do is wait for them patiently along with everyone else.

ETA means 'Estimated Time of Arrival'!

[storm sun]

👍

[fair merlin]

Some of it may never be fixed. Depends on which API.

But yeah, no ETAs.

[storm sun]

okey

[cosmic pawn]

Does anyone here actually run folia with a sizable amount of players

I need to ask questions

[cosmic pawn]

Hypothetically, if I had a 48k*48k world with 100-200 players online would folia break up into regions efficiently enough? You said players should be ~2000 blocks from eachother for it to work but that seems pretty excessive I feel like.

Basically I'm asking if I had 48k*48k world, with 100-200 players online, would there actually be multiple separate regions? Or would they all merge together

[rare hare]

Assuming you don't have all the players clumped together, yeah, there'd be multiple regions

[ashen meteor]

Hi, sorry to disturb you, but I have a question. We are planning to use Folia for our Towny server. Currently, we run four separate Paper servers with a total of 700 online players. The map size is 73728 x 36864, and the Nether/End dimensions are disabled. Players build farms like cactus and pumpkin, and occasionally, 40–50 players can gather in one region for PvP in player-made arenas.

We’re considering running two Folia servers on two dedicated machines with these specs:
Ryzen 9 7950X | 128GB RAM | 10GB UPLINK.

Would Folia be beneficial in these conditions? How should we allocate threads? Since you have experience with Folia, what are your thoughts on this setup? I’d greatly appreciate any insights you can provide.

[primal oyster]

idk why youre asking me

[livid crag]

You can try to survey how close players are typically are in your server to see how Folia can or cannot benefit you. This is something you have to do yourself. Asking Pedro wont really help you there

[haughty gale]

depends on the map

700 is a lot you would need like a 100k by 100k map

[ashen meteor]

We'll run two separate Folia servers, so the player count will likely be around 350–450 per server.

[haughty gale]

thats still a lot your main goal should be getting as big a map as possible

[ashen meteor]

We are using the biggest version of earth map (-36864 -18432 36863 18431)

[haughty gale]

when all the players are in one big region folia performs worse than paper
on 7950x3d towny server tps in a region would dip below 20 ~80-90 ppl (there was a lot more stuff than towny which affects performance) the map was like ~10k by ~10k
then we swapped to like a ~40k by ~40k and had like 4 regions each with 20-30 ppl and each region had 20 tps

also this was 1.19 or 1.20 so it might be a little better now

[haughty gale]

40k by 70k is decent

but idk if its enough for 400 players

u can use scale operation in world painter to 2x the size so its 80k by 140k

[ashen meteor]

we tested Folia with 200 real players on this map. TPS and MSPT were stable in regions with 1–5 players. However, in PvP regions where players gathered (20-30 players), TPS dropped to 17–18, MSPT was 20–30, and noticeable lag occurred in those areas.

[haughty gale]

yea same happened to us on 10k by 10k map at peace they were spread out and tps was fine but during war it was laggy because it was one big region

idk how you are getting 17-18 tps in a region with only 20-30 players

[pulsar schooner]

Folia

Folia is a fork of Paper that adds multi-threaded region support. Many plugins will require updating to support Folia. There is no ETA for publicly available builds.

For more information:

• Readme
• FAQ
• Regionising logic
• Detailed overview
• Javadocs

Folia will:

• NOT be backported to older versions <1.19.4
• NOT be merged into Paper
• NOT be ported to Fabric nor Forge

Stay tuned to #announcements for any further info about releases.

'ETA' means 'Estimated Time of Arrival'!

try running it outside OneDrive

syncing programs tend to mess with things

ok i will do it

i will will say if it works

also just saw that you reposted it ;_; don't do that

[pulsar schooner]

sry it was in the wrong channeld an d i havent deletet it yet

now its away

[finite hinge]

Build it in C:\Folia, Windows and/or git don't do well with long paths (Windows fails at it by default, git doesn't use the "new" API that would allow it to work anyway)

[dawn cosmos]

Hey, I'm also having Issues when building. I cloned the repo in C:/Folia

[arctic tapir]

try excluding the gradle and folia paths from your anti virus

[dawn cosmos]

Disabled my antivirus

still the same Issue

[sudden tusk]

Because it's Windows, I'd do a full system restart and try again

[dawn cosmos]

I tried it on my mac aswell, failed there aswell tho

[sudden tusk]

Share that error too please?

[dawn cosmos]

1 sec

[proud mountain]

at that point you should probably just use WSL

nope

just plain of cloned and ./gradlew applyPatches

I recloned the repository now in Desktop/Folia still this issue tho

[gilded mirage]

Hey

I am currently running a test on Folia with over 300 players, but I am experiencing some memory problems. Does anyone have any idea why this is happening?
https://spark.lucko.me/HR9nwjoJOt

[viral coral]

what is the memory issue

[viral coral]

right

you're giving it 100gb in -xmx flags

it will use 100gb or a high amount in general

the pterodactyl memory usage information is pretty useless

[gilded mirage]

Yeah, but it crashes tho

[silver sierra]

do not use createReobfPaperclip for 1.20.5+

[viral coral]

because you're giving the server 100gb

but 90gb in pterodactyl

[silver sierra]

use createMojmapPaperclip

[gilded mirage]

alright

[dawn cosmos]

tried arout a bit but still getting this error..

[pulsar schooner]

I am trying to upload folia to the Crafty server manager but its uploading for hours and nothing happens. Can anybody pls tell me why ?
