folia-help

[rancid pendant]

ngl discordsrv should probably wait for their rewrite to do folia support

[left swan]

It's better than another way I've seen someone say it

[left swan]

Convenient. More time for you to add support to Essentials

[rancid pendant]

80% of essentials works on folia

[livid crag]

[high spoke]

This project is so cool!!

[lime lintel]

folia will not help kitpvp at all. it's a hundred players in a small region. this region will all be running on the same thread anyway so will offer no extra performance benefit. fois helps where players are spread across a large area, not the other way around

[hardy ingot]

something like hungergames with 500 players on a very large map could work tho

[wicked mantle]

I still hope someone uses folia to host a map where players just survive as long as they can. If you die you're removed from the server. Since they can just spread people out super far and throw a few hundred players on the server.

[hardy ingot]

basicly hardcore smp

[prime juniper]

Uh, why?

Like, besides the feeling of superiority

[subtle wasp]

so there aren't fourteen reports of the same bug here while the bug has already been submitted and a fix has been PRed on github

[left creek]

Mutli-paper isn't already a good way to run thousands of players on the same map?

[livid crag]

We are not affiliated with Multipaper in any way. you should ask in their support discord. @left creek

Folia take a different approach as outlined on our official repo. You can spend some time reading it. @left creek

[prime juniper]

How can break paper plugins?

Dont think its a ticking system

[regal spire]

Can i ask? AMD EPYC 7281 10 Cores
and 64gb of Ram, is that ok to handle with 100 players?
not familiar with Multithread but would like to know
if its ok?

[dreamy dirge]

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'!

[spring herald]

Consider that they made a test with an Epyc CPU, 16 Cores and handled over 300+ players , so it should be plenty your configuration for 100 players (of course, here we consider plugins excluded from the server usage)

[left swan]

Definitely have a read of the information in the embed above too. If your server is one where a lot of players are going to be very close, Folia won't really be suitable because it'll just be one large region. It's great for game modes where player's are spread out.

[left creek]

I saw that folia cut the world in many regions to tick the where mommoth sync his world in Db and use many server to tick them, but what make you chose this approach compared to mammoth?

Mammoth seams to be stronger since it can be run one many computer at the same time

[livid crag]

You should reread the page again, that's not exactly how the region works. There is a reason why worldQL doesnt take off...

[karmic agate]

The title of the readme should just say "FIXED LAG IN MINECRAFT"

[proven tinsel]

FIXED LAG IN MINECRAFT*

[pulsar thicket]

Maybe this was already asked and I missed it, but is there possibility in the future of forcing folia to simply use one tick region per world, so that each world has its one thread but isnt split up? I feel like this wouldnt be an uncommon usecase and if regions can already split up multiple workls into multiple regions it probably shouldnt be too difficult to limit it to one region per world?

[arctic tapir]

why

[karmic agate]

I see how that could be beneficial for medium sized servers, but if it hasn't been done yet, there's probably a good reason for it

[pulsar thicket]

My thought process was also leaning towards minigame servers, whereas servers now often run one game per server, this would allow multiple games in the same server in separate worlds, bur keeping the entire world ticked on the same thread to ensure best performance for sth like pvp

[karmic agate]

I was thinking more on like servers that want to bring things like high view distance or multiple new dimensions, but that's about the same idea

I don't think Folia is exactly aimed for those servers anyways, but having some of its functionality being configurable to make it more versatile instead of requiring at least something like a whole Ryzen 9, or even if then, be more usable for cases like minigame servers, would be really nice

[pulsar thicket]

Yeah I understand that wasnt the goal, but it seems like a reasonable additional usecase with not a big amount of work? I havent looked at the internals on how difficult this would be to add, so im just assuming

Would be nice in any case

[karmic agate]

I know more than one server owner that's always called by the "If you have +100 players, you should have something custom anyways" argument, but because of the nature of their servers (tight budget), never really get a chance to do more than like a few basic custom plugins, so yea, having that kind of stuff publicly available would be awesome

[alpine mica]

May i ask some questions?

Can i use folia on a PC that running on dual CPUs? e.g. 12Cores + 12Cores

Does the Frequency matters? Can i use low frequency CPUs like E5 series?

[quaint ingot]

Folia worked fine on my dual socket test bench, from my understanding low frequency shouldn't have as huge of an affect on Folia as it would on Paper.

[quaint ingot]

Folia在我雙路測試平臺上可以正常運行，相對來説主頻對Folia的影響沒有Paper那麽大

不過個人推薦不要用洋垃圾

[alpine mica]

我也有同樣的想法

[alpine mica]

何出此言？

[quaint ingot]

洋垃圾説不準什麽時候就炸了...

[alpine mica]

噢噢，的確，畢竟不穩定

[quaint ingot]

好多洋垃圾tick單個區塊都很困難...

[alpine mica]

但至少應該效果會比高頻u好嗎？

[patent idol]

What is happening here 😳

[left dirge]

English please

[quaint ingot]

Sorry...

[alpine mica]

Sure

[quaint ingot]

I'll take this to DM

[drifting field]

Will folia have the benefits of pufferfish/purpur?

[viral coral]

no

[drifting field]

Is there a resource explaining the differences?

[viral coral]

plenty

[prime juniper]

is folia supposed to behave like this ?
(with 128GB Ram, 32Threads)

[hybrid shore]

If players are near each other then yes

[prime juniper]

nah they are spead over thousand of blocks

[hybrid shore]

Not enough

It must be min ~ 1500 blocks from each other

[prime juniper]

oof

[hybrid shore]

If a player is 1000 blocks away from different player it will be one big region

[viral coral]

yeah you only have 1 region in the overworld

either players aren't spread enough or there's not enough threads configured

kinda sounds like the latter to me because of the utilisation percentage

[prime juniper]

yeah tho i put that in the config

so it's pretty wierd

[viral coral]

don't do that

just because you have 32 threads available does not mean you should allocate all of it to threaded regions

[hybrid shore]

I don't like it either but well. ¯_(ツ)_/¯

[hybrid shore]

Would be nice to base this on view distance or configurable number.

[prime juniper]

then i put -1 ?

[viral coral]

i believe so

[prime juniper]

also it seems if the server is put under too much load it just dies or get killed

[dreamy dirge]

-Xmx controls the amount of heap memory assigned to the JVM, this does not include other memory used by java, or native memory used by other libraries such as netty (for networking) or SQLite. Please do not allocate all of your memory!

[hybrid shore]

How much ram did you assign?

[viral stone]

that's pretty much always setting Xmx too high so that the JVM is killed by the OS

[undone acorn]

that's a ton, jesus

[odd condor]

will folia work fine with 20k x 20k world for 300-500 players on 13900k? or 10k x 10k

[hybrid shore]

bad cpu, only 8 performance core's

I think ryzen would be better

And 10k is too small, 20k maybe

[inner swift]

Run the bundler jar instead

[timid grotto]

this is what a proxy is for. just run separate paper servers instead of multiple worlds for your minigames

[solemn zinc]

why is the region size set at 1500? Would it be possible to decrease this value? Then spreading out of players would be less of a problem. Somebody said it had to do with render distance + buffer. But even with a render distance of let's say 10 and a buffer of 5, a region size of 15x16=240 would be feasible, no?

region length* rather

[scenic sky]

merging regions does have some overhead

[viral stone]

And 10 render distance is practically more akin to like 20 chunks of loaded radius

[solemn zinc]

That's quite some overhead then

[prime glen]

Folia seems like exactly what 2b2t would need

[slim bolt]

As i know, it is not good to allocate too much RAM to paper. Does it work the same way on Folia and am i even right?

[late heart]

no, pretty much not (it's relative how many is to much)

[slim bolt]

Ok, thanks

So i should allocate as much RAM as i need?

[strange nymph]

2b2t needs more money, not more player slots.

[prime glen]

I meant performance wise, as an issue on there is the high amount of players with a high amount of loaded chunks, farms and redstone machines

[viral coral]

it's not a problem until you need to analyze a heap dump

[late heart]

dl y (sorry it was by an accident)

[viral coral]

yes but good luck analyzing a 90gb heap dump locally

not if you have some serious memory leak where it actually starts to use 90gb

[prime glen]

probably not gonna use only 5GB

[viral coral]

otherwise why else am i going to dig through a heap dump

[spring herald]

Just a quick question, what can be minimum requirements for Folia?

Ok the recommended (more cores and threads are good) , but for the opposite ?

[arctic tapir]

mostly same as paper

[spring herald]

So... technically if you use one core, folia = paper? 🤔

[prime glen]

https://paper-chan.moe/folia/ better take a look here

it lists the specs used for their test run of folia

[arctic tapir]

folia would be worse then paper

[prime glen]

so you can have a pretty good point of reference

[rich violet]

Has anyone converted plugins like worldedit and essentials to work with folia yet?

[wicked mantle]

Essentials in in-progress and I believe FAWE works

[rich violet]

out of the box?

[wicked mantle]

or at least has a PR with a build that works

[rich violet]

ah nice

[wicked mantle]

Last I heard jroy said essentials was at 80%

[daring nimbus]

FAWE folia support is still pretty experimental and not all features work. And I think you need to build the branch yourself

[exotic stirrup]

Build it self, you are right. Maybe i can ask NotMyFault to deliver a pre-build jar for reporting issues

[exotic stirrup]

@wicked mantle @rich violet I attached a link into my pr on FAWE with the current download link. Feel free for testing

[blissful basin]

A lot of plugins have support for folia as of right now

[timid grotto]

no?

[blissful basin]

Surprisingly a lot compared to how long Multipaper was there and almost no-one updated for it

[timid grotto]

most plugins dont support folia yet

[finite hinge]

multipaper is distributed computing, the hardest thing you can do in programming

[blissful basin]

I said it's a lot considering the time since public release

[finite hinge]

folia is "only" multithreading

[blissful basin]

API wise it's easier

But it's harder to make sure everything works on MP than folia

[viral stone]

multithreading is a lot more accessible dev wise for testing, even if it performs like shit on your hardware, vs tryna get an entire stack setup

[tacit tartan]

Considering LP does not yet have a stable folia impl, I think that's a showstopper for damn near every server

[strange nymph]

https://github.com/BlockhostOfficial/folia-plugins

It’s happening extremely fast.

[blissful basin]

Yep I updated too to stay relevant

[tacit tartan]

considering that list includes LP, it's either inaccurate, or counting unstable branches as "supported"

[sudden tusk]

I like how that list says support or just working on support 😆

[blissful basin]

How can I get on that list 🤣

[strange nymph]

Well yea, but if there’s a branch or a pull request then the chance of it not happening is 1%.

[next bloom]

that seems like not a useful list. How do I differentiate between the two

[tacit tartan]

oh well if it also includes "working on it" then what's the point?

[strange nymph]

The point is so you know that you will be able to switch in Folia in some time.

[blissful basin]

Can you put my plugin into the list too 🤣

[strange nymph]

DM.

[blissful basin]

I will probably join you soon

[glossy locust]

I've always considered MP as too unsafe for a survival server

[blissful basin]

Once PureGero comes back from studying it's gonna be better

Yeah that's why we built economy around tasks instead of items

[paper stone]

Small suggestion for your next commit: change GeyserMC to Geyser since GeyserMC is the org behind Geyser and Floodgate

[livid crag]

Don’t worry https://hangar.papermc.io/tag/folia soon

[late skiff]

is folia available to download?

[dreamy dirge]

⚠️ 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.

[idle furnace]

@tranquil epoch could sell beta versions, if 1/4 of the people, asking for it, buys it he would get rich 🙂

[left swan]

Leaf doesn't do this to make money, so I'm sure he wouldn't be interested in that.

[subtle adder]

I got some messages from people asking me how to download folia and they say it would be unnecessarily complicated (i have not looked into folia further then reading the announcement and the README.md). Is there anything special about building folia in comparison to building paper? Or is it just people searching for official download links?

[idle furnace]

I know, was a way of joking with the situation

[idle furnace]

Nop, we only want to make sure people know what they are doing when testing it

[tacit tartan]

it's most likely people not knowing how to build anything in the first place, since yeah folia is just a standard paperweight fork

[subtle adder]

Is is so unstable that this is necessary?

[tacit tartan]

yes

[idle furnace]

If we give them the jar, they would come back reporting problems due to the fact most of plugins are currently incompatible

[tacit tartan]

it's really only out so plugin devs can get working on compat

[idle furnace]

But I consider it quite stable already

[inner swift]

Well, main concerns are that it's not compatible with any Spigot/Paper plugins unless they manually add compatibility and that in low core setups it's worse than Paper

[tacit tartan]

also there's some major systems that simply aren't implemented rn (scoreboard), as well as who knows how many uncaught bugs
like Leaf's good, but still human, and they probably missed a few things

[subtle adder]

so it is paper-plugin only?

[tacit tartan]

worse, plugins must be explicitly compatible with folia

[subtle adder]

oh i see

[tacit tartan]

in order to make the changes, Leaf had to nuke the scheduler system among other things, which damn near every plugin relies on

(there's of course an alternative to the old system, but it requires code changes)

[subtle adder]

yea i was asked too if i would „update“ some of my plugins to folia and i said as a precaution that this is to complicated for the revenue i would get out of it..

[tacit tartan]

I mean depending on the plugin it might require very little changes

[subtle adder]

is there a list of breaking changes?

[shell violet]

https://github.com/PaperMC/Folia#current-api-additions

read here down to "planned API changes"

[subtle adder]

i like the „could be more“

[shell violet]

already one thing not listed there is the whole conversation API

[subtle adder]

yea if there is a stable and supported build i will think about migrating at least some of my plugins (that also is a huge pain to maintain paper and folia at the same time then, right?)

[shell violet]

it depends what you're plugins are doing

see pins in #folia-dev, there are some links to open source plugins that have updated and their diffs

[frank prism]

they are thinking about potentially adding API to make folia plugins compatible with paper

[subtle adder]

currently im not at home and staying abroad with only my ipad so i will look into this later, thank you!

[shell violet]

yeah, right now the only thing that is part of folia that isn't part of paper is the new scheduler API

the other major changes are all just extra possible conditions you need to account for that will never occur on paper. but, accounting for these conditions will not break your plugin on paper either

[frank prism]

they will probably replace some more stuff when fixing all the broken API tho

and datapacks arent supported on folia

[raven compass]

Is this still the way to get player object from uuid?
Bukkit.getServer().getPlayer()

[hexed ice]

yes

[fossil vigil]

Will folia benefit from dual socket systems (dual epyc, for example), or is the CPU communication overhead not worth it in this case?

[inner swift]

It does seem to be a concern, in the test server the second CPU was disabled to avoid NUMA penalties

[pseudo ibex]

Is there a way to load up worlds than the world, world_nether, world_the_end?

[finite hinge]

I don't think NUMA will hurt that much it was just that we didn't need more than 64 cores so why take the NUMA hit from the scheduler being dumb

[wise vale]

api is broken at the moment so nope

[wise vale]

in-case you run into issues with api there is list on github readme https://github.com/PaperMC/Folia#current-broken-api

[thorny snow]

So is there no nether & end support?

[livid crag]

Wdym? Where did you read that @thorny snow

There is nether and end

[thorny snow]

If interacting with portals is broken...

[viral coral]

api

[thorny snow]

And world loading/unloading

[viral coral]

nether & end work fine

[thorny snow]

And their portals?

[viral coral]

they work

APIs are the stuff plugin developers touch

[thorny snow]

I know, but I thought if they are broken, it shouldn't work

[arctic tapir]

the api part is broken

not the portals in the world

[thorny snow]

ok thanks

In the test server there was no nether also

So I thought...

[livid crag]

As it stands right now you can play Minecraft on Folia until you beat the dragon as a player, the only thing you will notice that’s different is end credit not working @thorny snow The only “broken” part is plugin supports and certain APIs that normal player will not need to worry.

[thorny snow]

got it

[thorny snow]

Is it normal to that THAT long?

[sudden tusk]

What's the CPU and what type of drive? (SSD or spinny disk)?

[wicked mantle]

windows makes it super fucking slow too

[viral coral]

on windows, yes

[sudden tusk]

Well, not that long unless it's like an atom cpu and a 5400rpm

[thorny snow]

I7 7700

Sata SSD

49 minutes lmao

[next bloom]

Oh you are building on windows

Yeah, that’s gonna be the issue

Use wsl or some not windows OS

[sudden tusk]

50 minutes feels ridiculous either way though

[wicked mantle]

eh not if an antivirus is attempting to run threat detection of the directory

[celest forum]

i built it in my one drive folder and it still only took less than 5 minutes

50 min is an extreme amount for a 7700k

i have a 10700k and there’s no way that’s a 45 min diff in 3 generations

[sudden tusk]

Ah, that could be it. I have the folder I put all projects in whitelisted.

9600k here, roughly 5 minutes to build as well.

[sly elm]

mine used to take well over an hour on windows

its a couple minutes for me on wsl though

[finite hinge]

On Windows on a HDD it was definitely over 30 minutes, don't remember how long it ended up being

SATA SSD isn't that much better than a HDD although it should still be way better for dealing with lots of small reads like patching

[paper stone]

I have an NVME and with WSL it took more than a hour

With a 6c/12t

[nova spire]

error
what to do?

[viral stone]

read the log and see if it says why it failed

[blissful basin]

Did you build it inside WSL file system or did you leave it on Windows and just cded to it

[paper stone]

inside WSL but I think I need to allocate more ram to WSL

3GB isn't enough but idk how to do it

[blissful basin]

It's dynamically allocated

It uses hyperv dynamic ram

[paper stone]

idk it was stuck to 3GB then since I do have 16 and was doing nothing else...

[blissful basin]

Well because Gradle did not see more memory it didn't try to use more

[viral stone]

There is a memory limit

by default these days it's apparently 1/2 of the ram, but, idk how that's set, etc, etc

[pliant wedge]

I want to use GravityControl, but I get an error. How can I use it?

[blissful basin]

It doesn't support folia

[pliant wedge]

oh,really?

[hexed ice]

the error is right there in plain text

plugins have to explicitly add support for folia

[blissful basin]

Here is a list of plugins supporting folia

https://github.com/BlockhostOfficial/folia-plugins

[pliant wedge]

thx 🙂

[blissful basin]

Most plugins just arent supported

[pliant wedge]

ok

[blissful basin]

For example my plugin (MineStore) is the only economy plugin out there

[prime glen]

Ayo it's just economy, why aren't others supported 💀🤣

[blissful basin]

Probably because Vault did not update

[prime glen]

Wouldn't it just be a matter of putting that one line in plugin.yml?

[blissful basin]

No 🤣

[hexed ice]

for vault it would be, it's just an API

[blissful basin]

Yeah but for the economy plugins it wouldnt

[prime glen]

yea it would

those shouldn't depend on chunks or scoreboards

only keeping track of numbers

[blissful basin]

They must use schedulers

If they want to use any kind of database

[teal umbra]

Vault has some scheduler usage as well iirc - it had an open Folia support PR

[livid crag]

It’s not even a month after repo is made public. Not all developers are sit idle and ready to work on a project. Just be patient.

[blissful basin]

If your project is well abstracted it is like max an hour to make it compatible

[livid crag]

[blissful basin]

Well I just have method runOnMainThread()

I just implemented that to use the folia scheduler

[teal umbra]

I mean, depends on what is your project lol

Something that deals with a lot of world modifications could be practically a total rewrite

[blissful basin]

Yeah

But most plugins should be fairly easy

[spark fulcrum]

self proclaimed rebdering god

[magic pond]

This may be a dumb question, but is this possible to compile on macos? iv been unable to and am curious if its just not able to

[hexed ice]

of course that's possible

[magic pond]

ah so im not just dumb!

i mean maybe i am, but at least its not that lol

[shell violet]

What issue are you encountering?

[magic pond]

im pretty sure im missing dependencies, or something like that

import io.papermc.paperweight.tasks.RebuildGitPatches
       ^```

[hexed ice]

make sure you git cloned it and didn't download it as a zip

[magic pond]

i did do git clone, but i may just redownload it just in case now that you mentioned it

i used the link

under code

[hexed ice]

show the full error in that case

[hexed sky]

anyone know how to unpatch sand dupe ?

[sudden tusk]

In folia? You're kinda on your own 😆

[dreamy dirge]

Having problems with TNT Duping, Bedrock Breaking or Sand Duping Vanilla Exploits? See: https://github.com/PaperMC/Paper/issues/3854 for information.

[viral stone]

oh, if that's the one you need the plugin for, you'd need to wait for the plugin to be updated or whatever

or update it yourself

[magic pond]

okay its fairly long

but i think it just stems from the first error

[fierce knot]

message.txt by @magic pond: https://pastes.dev/mZnPaIr6gO

[viral stone]

Did you just clone the folia repo?

[magic pond]

yes

i have a feeling im missing dependencies

[viral stone]

probs pulled some corrupted gradle jars or something

[magic pond]

hm

that would be weird if i just cloned it tho right

[viral stone]

there was a gradle flag to tell it to refresh dependencies

[arctic tapir]

--refresh-dependencies

[viral stone]

yea, forgot what the seperator was :L

[magic pond]

okay wait maybe i did it

im not a gradle guy

but i now have a jar

though i think its too small

[viral stone]

you apply patches, and then you create a bundler jar or whatever, the thing things in the build/libs folder

[magic pond]

ahh

okay

is this really not documented anywhere? i mean i know this is not for general use as its early test builds, but still i feel like there should be a small sorta guide

easy to get lost

[viral stone]

It is covered in the readme for paper

[magic pond]

it does seem to be building something now that i ran the apply patches

[viral stone]

exact same process

[magic pond]

ah that would be useful

why isnt that mentioned anywhere? i mean it does make alot of sense since its a fork but

i feel like there should be something to point someone

i dont have a ton of dev experience with projects like this

[sudden tusk]

The assumption is that, at this point, if you're going to be running the highly experimental code that is folia then you are skilled enough to set this all up yourself or are paying someone who is (because folia's good for huge servers running on massive dedicated boxes)

[magic pond]

yeah that is fair, i get that

but still, for a random guy like me who wants to just see whats up, i think there should be at least a mention of how to build it

even if thats just, "hey its the same as paper"

[sudden tusk]

There is. It's on the paper readme.

[magic pond]

but there is no mention of that on the folia readme

[sudden tusk]

When we think it's ready for more people to start testing, we'll make it more obvious how to set it up.

[ionic wadi]

How can i compile Folia? When i compile it get a Jar with just a manifest in it but nothing other?

[viral stone]

see the paper readme

[magic pond]

Just add a mention to that on the folia readme, itll save everyone time

[viral stone]

too dead, somebody send a PR maybe, idk

[ionic wadi]

It says they cant reconise the command

Im on WIndows 11

And thats the Folder with the Folia Master Files

[viral stone]

...

1. first step is to clone the repo, not download it

[ionic wadi]

Ohh i wasnt in Powershell

[viral stone]

2. don't run in a folder tainted by onedrive

[ionic wadi]

Okay how do i clone it?

[magic pond]

i wouldnt recommend having it in ondrive

lol

[ionic wadi]

Its just the name i cant change that One Drive isnt enabled

[viral stone]

you'll wanna do it on the top of C drive anyways

[viral stone]

windows has stupid limitations which causes issues

you need to install git, and then clone the repo with git

[ionic wadi]

Whats the command for cloning?

[viral stone]

git clone <repoUrl>

[ionic wadi]

Okay got it

Still get this error. I cloned it properly

[arctic tapir]

are you still in one drive

[ionic wadi]

No

Wasnt before just the name of the folder

[viral stone]

see the full output of the thing

[arctic tapir]

try at the root

[ionic wadi]

Thats the full output

[inner swift]

Error and solution are written in your screenshot

[ionic wadi]

Thats the Stacktrace

But cant read anything from it realy

[viral stone]

above that..

Like, literally, read from the top

[ionic wadi]

That with the account thing do i realy need to log in or sum?

[viral stone]

you just need to tell it who you are

git requires that info because 99% of people using git generally intend to use it for actual work

[hard vector]

Hello. My players are building very very big farms using a lot of pistons and hoppers. Now I have 24.000 pistons on my server. These farms are incredible big. It causes lags and high mspt

Any ideas how to handle it on survival server?

[blissful basin]

It's folia server right?

Well in that case you need to make something like insights for folia and limit the amount of pistons per chunk

[hard vector]

No, just paper. 50mspt with 60 players with 5000 entities and 24000 pistons. When it Drops to 5000 pistons then mspt goes to 30

[blissful basin]

Why do you use folia help than

[hard vector]

Oh, sorry

[blissful basin]

https://www.spigotmc.org/resources/insights-super-configurable-region-limits-asynchronous-scans-1-19-2.56489/

Use this plugin to limit number of pistons in chunk

It's not retroactive thought

[hard vector]

Thanks, I know this plugin but I thought it is only for scanning regions, not for limits. Now I am surprised

[blissful basin]

Frank only makes good plugins 🤣

[hard vector]

And this just delete above limit pistons?

[blissful basin]

It allows you to configure a limit of pistons in chunk

But it's not retroactive

[hard vector]

Okay, thanks. I will read about it

[hard vector]

Its me again. Sorry that I am continue this topic here. Is it possible to disable ticking pistons, hoppers when player is more than (for example) 30 blocks away from them?

Without modifying simulation distance

Okay thanks, so I will focus just on limiting it per chunk

[jaunty talon]

Is folia more stable or still very unstable?

[blissful basin]

More stable than when?

[jaunty talon]

like is it stable enough for 100+ players

[blissful basin]

If they are far apart than yeah

[prime glen]

dude this is pre alpha stuff rn

A bunch of API stuff is broken, not a lot of plugins made to work with Folia either

[jaunty talon]

Oh

[slim bolt]

Things like player.addPotionEffect should also be used with the scheduler?

[viral stone]

once again, that's mutating entity state

[slim bolt]

Ok, so for example sendMessage can be used without it?

[viral stone]

sendMessage afaik should be fine given that it doesn't modify state

[late heart]

Utilisation: 8,6% / 100,0%, is it normal if I set 32 threads with -XX:ParallelGCThreads=n ? Or this number is devided by the thread counts thus making 100% the maximum

[viral stone]

That's nothing to do with utilisation?

[late heart]

ah okay, thats threaded-regions in the config that I was looking for

[pliant wedge]

How can I get Folia for 1.19.3?

only1.19.4?

[hexed ice]

1.19.4 only, there should be no reason why you'd want an older version

[arctic tapir]

basically yes

[pliant wedge]

Ok

[celest forum]

unless something changed viabackwards didn’t update yet

[subtle oriole]

https://gyazo.com/af4b7b74719b7951cdf9c34b14a3d952.png

[pliant wedge]

Monster done not move! What should I do?

Is this a bug in Folia?

[arctic tapir]

try to reproduce on paper

[undone vale]

why does folia not have a main thread?

[glossy locust]

it has a main thread

[undone vale]

never mind then

[glossy locust]

but you probably meant to ask another question

[sudden tusk]

I feel it's deceptive to say "it has a main thread" when it clearly is a very different behavior of a 'main thread' from what anyone is used to.

[blissful basin]

I mean GlobalRegionScheduler is kinda main thread

[sudden tusk]

There is no 'main' thread on which chunks and entities and players are processed, because each region (see the readme) has its own 'main' thread to operate on. It's kinda the whole point of the system.

[sudden tusk]

Kinda but also kinda not.

[undone vale]

ok

[sly elm]

isn't global region scheduler just kind of "main" relative to the region scheduler thread pool

definitely not like the main thread of a normal minecraft server though

[blissful basin]

Yeah

But it is the closest thing to main thread 😄

[sly elm]

closest except in terms of usefulness, since you should not be scheduling most things to the global region scheduler

[sudden tusk]

If I ask "do you have any knives?" and you answer affirmatively, I would not expect to be given a spoon and told "well it's the closest thing I have"

[sly elm]

great analogy, love it

I think the obvious things most people seem to miss here is

• Entities go on the entity scheduler
• World stuff goes on the specific region scheduler (not global)
• Plugin code unrelated to minecraft should go on another thread (but not the global region scheduler, this is not a dumping ground for stuff like the main thread in bukkit)

[blissful basin]

Well I think that the way current plugins are done are inproper

I think each plugin should use its own thread

[sudden tusk]

Use its own thread for... what? Plenty of plugins have no need for anything off the main thread.

[blissful basin]

Yeah but than people just access databases on main thread not knowing they are on main

Because they are new to this

So I think everything should be its own thread unless it is run on main thread on purpose

[sly elm]

I mean that's tough, in programming specifically you make the assumption that the programmer knows what they're doing. Otherwise everything falls though.

[sudden tusk]

So... because a handful of devs getting into databases make mistakes you want the other 99.9% of plugins to have to learn multithreading considerations?

[sly elm]

There is no reason to really idiotproof an API because that hurts normal programmers at the expense of idiots.

or generally has very limited use outside of trying to solve a non-existent problem

[blissful basin]

Well I think every programmer should be able to do multithreading

[sly elm]

Well the reality of that is concurrency and multithreading is an advanced topic, so you shouldn't expect that either

but folia is a specialty fork of paper designed for this, normal people won't be using folia

servers using folia will need to find developers who are familiar with these concepts

[blissful basin]

Well since it was made by paper dev it is gonna be popular and normal people are gonna use it too

Unlike Multipaper

[sudden tusk]

Long-term, sure, somebody who plans to be an actual developer as a career absolutely should develop this skill. We're talking about folks just learning how to code and you're saying there should be an incredibly high barrier to even getting started.

[sly elm]

We can't stop people from using it against the recommended use case, but that's on them at that point, not us 😄

yeah a lot of plugin developers are not career programmers

[blissful basin]

Yeah the thread idea was stupid

Screw that 😄

[blissful basin]

I am not one either

I am just a high school student

[sly elm]

yeah gotcha, not specifying anything

the main point was there's no need to be throwing people in the deep end for no reason

[blissful basin]

I get your point

[sly elm]

if you understand more advanced topics I'd trust you use them appropriately

some people don't

[blissful basin]

I was just trying to say that multithreading aint that hard

[blissful basin]

But I would like to be full time in future

[charred galleon]

Hi, Folia will be available for download?

[dreamy dirge]

⚠️ 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.

[calm raven]

I have a question: What versions of minecraft will folia be available for in the future ?

[late heart]

1.19.4+ I assume

[dreamy dirge]

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'!

[prime juniper]

I have been able to build Folia from source, but how do I run it? I tried java -jar folia-server-1.19.4-R0.1-SNAPSHOT.jar
and I get:

no main manifest attribute, in folia-server-1.19.4-R0.1-SNAPSHOT.jar

[arctic tapir]

wrong jar

use the one on /build/libs

main folder

[prime juniper]

I still get ```
no main manifest attribute, in folia-server-1.19.4-R0.1-SNAPSHOT.jar

[arctic tapir]

still the wrong jar

[prime juniper]

I'm inside /build/libs

oh

[arctic tapir]

and wrong folder

[calm raven]

1.19.4...does anyone know of plugins for that version that limit chat reporting ?

[prime juniper]

So then, what is the right folder?

[arctic tapir]

the main folder

then /build/libs

[prime juniper]

what is the main folder

[arctic tapir]

where you see Folia-Server Folia-API etc

[prime juniper]

yeah

I'm in the main folder

the root of the git project

[arctic tapir]

then go to the build/libs folder there

[prime juniper]

I still get ```
no main manifest attribute, in folia-1.19.4-R0.1-SNAPSHOT.jar

[arctic tapir]

still the wrong jar

[prime juniper]

I'm in Folia/build/libs

[arctic tapir]

what command did you do to build

[prime juniper]

./gradlew build

[arctic tapir]

wrong command

https://github.com/PaperMC/Paper#how-to-compiling-jar-from-source

[prime juniper]

ohh

alr

thx

[prime juniper]

Also, what is the most recommended CPU to use for Folia? I am running a small AArch64 (4-core) server with 8GiB of RAM, is there any better ARM, RISC-V, or AMD64 processor that I can get out there?

[inner swift]

Recommended minimum is 16 physical cores

[prime juniper]

yes, but what is the cheapest architecture?

for a Folia server?

[inner swift]

Probably amd64

[prime juniper]

oh

because I've seen that the prices with AMD64 processors grow exponentially for double the cores

Is Folia horizontally scalable?

What I mean by this, is it possible to seperate the Folia server to multiple devices?

[timid grotto]

no

[prime juniper]

oh

[near crater]

Why would you need to do that?

[prime juniper]

What if others are on a budget?

[viral stone]

I mean

[prime juniper]

I mean the google search engine doesn't run on one server (for example)

[viral stone]

if you have the player count for folia

[near crater]

Folia isn't for people that are on a tight budget.

[viral stone]

but don't have the cash for it

you probably fucked up

[timid grotto]

if you dont have money to spend on a better server then you probably dont need folia

[prime juniper]

alright

[livid crag]

500 concurrent players 495 free to play

[timid grotto]

if your trying to run a server for a few friends, use paper

[viral stone]

Like, at the end of the day, Folia is for a niche use-case and has the hardware requirements of such

if you want distributed stuff, see multipaper, but, just note that you're generally going to require your own dev team anyways, which like, "glhf"

[prime juniper]

I've actually used multipaper before

not going to lie, it wasn't that bad

I was just thinking that Folia would be better since it's more closer to original PaperMC

[timid grotto]

folia (probably) is better

[viral stone]

never implied it was bad or anything, just that you'd generally require a dev team to actually cater to the platform

[timid grotto]

at least overall

[viral stone]

Folia is more accessible to devs given that it doesn't require as complex of a setup/change

multithreading is much more accessible to devs than distributed bs

[prime juniper]

Consider that Folia server can't be distributed into multiple servers, and multipaper can

[timid grotto]

ok but in practice do you actually need to use use multiple servers

[prime juniper]

When you want a CPU with more cores, usually the price will be exponentially higher (Like I mentioned earlier). Eventually, someone will reach the point where it is extremely expensive to buy a CPU with more cores, so they would have to get a seperate server

[timid grotto]

if they have the player count to need more cores to run the server well on, then they probably have enough money to upgrade to a better cpu

[viral stone]

at the end of the day it's a different setup care

folia is designed for a single CPU environment, which is much easier for devs to access, and generally more in line with the type of hardware people are using for servers these days

distributed is another solution, which is what multipaper does, but is generally less accessible and more cludgy to program for

[prime juniper]

well

I'll give Folia a try

[hardy ingot]

an amd epic 7502p (with 32 cores) and 128gb ddr5 server 'only' costs 150€/month tho

if you actually need folia you should be able to afford that, high clock count isnt that much important if you can distribute work over all cores (would still be better tho)

[finite hinge]

The setup of Folia probably makes a good base to make a new MultiPaper (well, MultiFolia) from

I dunno, I guess doing that cleanly would probably end up with some jank on the client side when it came time to merge regions

Thinking was Folia is already isolating things so you could take that logic and just run different instances instead

Oh yeah I'm not saying it'd be useful

Just probably easier to start from Folia than Paper if you were to start from scratch on something like that

Folia is already doing the work to figure out what can be isolated, ensure they run when isolated, and how to merge them back together when they can't anymore so that would leave you to figure out how to sync things between servers on the spin up and merge times

We're already assuming you have a $1,000,000/year dev budget, at minimum

We're talking about building a custom distributed MC server and all your plugins for it

Building that is definitely a multi-million dollar expense

Well, you might be able to do it for only 1 million

[glossy locust]

doesn't seem that expensive...

[celest forum]

a server with 6000 players could definitely purchase some sort of epyc cpu with 192 cores and colocation it

[glossy locust]

I'd like to see a spark of a server running folia

[finite hinge]

Is DonutSMP vanilla settings

[viral coral]

no

[finite hinge]

If someone started from scratch on a MC server they could make something that would run vanilla-like settings at 30 players a core and scales up to 192 cores, probably

But that's a whole different game design so you can't patch MC in to that

[timid grotto]

making a new server software scale is easy, making the vanilla server scale is very hard

[tranquil epoch]

can definitely run 30 per core

just need to consider the other threads in the system

[pulsar oriole]

~~Should I choose Paper instead of Folia for a 4core CPU?~~I didn't see the pin, sorry.

Also, is there a possibility that the development of Paper may be terminated in the future?

[wicked mantle]

Yes and no

[pulsar oriole]

Thank you 😘

[fossil vigil]

everything comes to an end, eventually

[next bloom]

I bet you a million dollars paper (the mc server) won’t be around in 100 years

[fossil vigil]

that will be worth about $100 in todays money at that point

[hardy ingot]

at some point minecraft will either simply die or someone has made a well made and supported server alternative that is better than any vanilla fork/patch anyways

[royal swallow]

The minimum 16 cores recomendation. How many active players is that based on?

I have 8 cores and ~50 active players. I mean 8 cores might be good for that playercount?

Im going to try a switch to Folia from paper, havnt done it yet. Im running a SMP with farms and high entitities counts. So yes, im in need of folia.

[vague kite]

For optimal experience, you will need 1 core per each group of players in the same area (a group may also only consist of 1 player). If you have more player groups than cores, groups will start sharing the cores (the whole vanilla only shares 1 core after all). There are really no ideal numbers telling you how many you need, but generally more cores = lower chance of sharing & overloading.
With 8 cores on Folia, you will generally be able to handle up to 8x more players than you would on Paper.

[scenic sky]

8 cores will most likely be a bottleneck with folia

[fringe gazelle]

just curious, what would be the bottleneck?

[livid crag]

his low core count (?)

[scenic sky]

the server will choke because there aint any more cpu to use

[true ether]

So I compiled the source to jar with no problem but when i try to run as i do with paper this happens : Error: Unable to initialize main class org.bukkit.craftbukkit.Main
Caused by: java.lang.NoClassDefFoundError: joptsimple/OptionException

[hexed ice]

https://github.com/PaperMC/Paper#how-to-compiling-jar-from-source

[true ether]

I did jus that

just*

[hexed ice]

you're not using the right jar then

[scenic sky]

is the jar size something like 80 bytes

[true ether]

Mine is 20mb

[scenic sky]

that isnt the right jar for sure

[true ether]

Thats the name : folia-server-1.19.4-R0.1-SNAPSHOT-mojang-mapped.jar

[hexed ice]

it's in build/libs like it tells you

not in Folia-Server/build/libs

[true ether]

It works now Thanks.

[true ether]

Is there a way to download older versions like 1.19.3?

'ETA' means 'Estimated Time of Arrival'!

[keen fable]

just use viaversion + viabackwards

[timid grotto]

why would you want specifically 1.19.3, cant use 1.19.3 paper plugins on folia anyways

[hardy ingot]

not really if they use any feature that is either broken or impossible in folia (which is almost everything basicly)

[jagged ether]

Folia won't load plugins which don't explicitly say Folia is supported

and if a plugin was made for 1.19.3 it likely was made before Folia was released therefore couldn't possibly know of that flag

[hardy ingot]

my point was that they wouldnt work no matter if they have that flag or not

[jagged ether]

Well stuff that doesn't touch the scheduler would probably work just fine

once the API actually works just fine

[sudden tusk]

As long as they don't...

schedule any tasks ever
react to events by modifying another part of the world (or a different world)
iterate the player list to do anything to multiple players
use scoreboards
load worlds
have commands that affect another player
...

[sly elm]

thanks, I don't think any of my 100 plugins do that

time to run folia

[drowsy mountain]

anyone know which plugins are supported at this current time

[jagged ether]

someone's made a list, you can search this channel
https://github.com/BlockhostOfficial/folia-plugins

[drowsy mountain]

thx

[blissful basin]

How much do I need to donate to be Sponsor? 😄

Sorry found it on opencollective

[jagged ether]

Actually does the Folia's BukkitScheduler still throw for async tasks

[vast dust]

Do we have any documentation on which specific APIs are supported, how to migrate, or details on which actions need to be schedule versus which are thread-safe?

[timid grotto]

read the readme

[sly elm]

@strange nymph w.r.t. #folia-help message you don't have to compile chunky yourself, it's on both CodeMC and Github Actions readily available, just no release yet

[vast dust]

I have read the readme.

[sly elm]

the tldr; for migrating is don't use bukkit scheduler, use the specific scheduler on the entity / region, etc

[sly elm]

I think this is a good list to look out for

or rather, things to consider if you're doing any of those things currently

if you're not sure you might also just want to look at some existing plugins that have migrated and the kinds of stuff they have to deal with to make it compatible

[strange nymph]

Thanks. I've updated it - https://github.com/BlockhostOfficial/folia-plugins.

[sly elm]

thanks, hopefully easier for people to find now 🙂

[blissful basin]

Maybe it can be pinned

[true ether]

Is there a way to force load a plugin doesnt matter if it crashes because Im using a backuping plugin so that doesnt use the Scheduler

[glossy locust]

unzip it, change plugin.yml, rezip it

[true ether]

The plugin?

[blissful basin]

Yeah

What else?

[true ether]

I dont know but generally where should the plugin.yml be?

[blissful basin]

If you don't know where it should be you shouldn't edit it.

[true ether]

Thats true but Is there another way to force load the plugin even if it crashes?

[viral stone]

No

without modifying the server to ignore that check

the only option is to modify the plugin to pass the check

[blissful basin]

Why do you even want to do that

[true ether]

Cause I dont have the best hardware with my server so Folia would help a lot and plus the host is Oracle Cloud and sometimes I just need the backup and this is the most reliable way to get it

[hybrid shore]

Cause I dont have the best hardware with my server so Folia would help a lot
Nooope

[viral stone]

backup plugins are the least recommended way to do that

[hybrid shore]

You need at least 16 cores

[blissful basin]

Not true

You don't need them

[viral stone]

running folia on something with low core count is generally dumb

[blissful basin]

It's just recommended

[true ether]

I just want to try it

if it would be better

[teal umbra]

For a reason

[blissful basin]

Imo it should be 16 threads

Instead of 16 cores

[viral stone]

Hey, I'm all in favour of allowing people to shoot themselves in the foot

[true ether]

Its 4 Cores

I know its a bad idea

but

[viral stone]

HT slows down cores

[blissful basin]

💀

[true ether]

Maybe... It would be faster

[viral stone]

generally smart schedulers will try to avoid doing heavy shit across 2 vthreads

[hybrid shore]

No

You should use paper or paper fork if you have only 4 cores

[true ether]

I do i just want to try folia

[blissful basin]

Than delete all plugins and try it

[hybrid shore]

For testing 4 cores is fine, but not for production

[true ether]

Yeah

[blissful basin]

Delete all plugins than

[viral stone]

I mean, if they wanna do it, let them; just, ofc, you're shooting yourself in the foot here and nobody will care when you cry about the pain

[true ether]

Thats what im gonna do

[true ether]

Why would I

[sudden tusk]

Folia is something that's only going to improve your server if you are running on something like a super-powerful dedicated server all by yourself. Anything with 4 cores isn't gonna improve and will almost certainly be worse PLUS you'll be missing a ton of plugin functionality.

[oak python]

Anyone knows how i can find plugins that supports Folia server type?

[glossy locust]

[glossy locust]

full error in pastebin?

edit: nvm discord mobile was being stupid

[keen fable]

This is the full stacktrace
Note: we're running with 32 view distance

[knotty finch]

what viaversion like plugin should i use for folia?

[blissful basin]

Viaversion

There's really no alternative

Why do you even want an alternative?

[foggy blaze]

Prolly didn’t realize that via had Folia support already

[blissful basin]

In that case this https://github.com/BlockhostOfficial/folia-plugins

[blissful basin]

Yeah that's why I asked why he needs an alternative

[tranquil epoch]

I don't know what could cause that; is the player that died due to player2 the same player that tripped the exception?

[keen fable]

Yes! It happened 2 times (when the player click on the respawn button i think, but i'm not sure)

[knotty finch]

Viabackwards doesnt work

nevermind

[blissful basin]

https://github.com/BlockhostOfficial/folia-plugins

Just read this

[knotty finch]

i'll try from that

yeah

yeah i saw 10 seconds ago

Ty.

[blissful basin]

Oh ok

It should work

[stiff ferry]

Has anyone managed to run Folia on Xeon Phi hardware? Interested in if/how that could work

I'm pretty sure it's not possible, and even if it is it would be super slow

[inner swift]

Probably wouldn't run well at all

[stiff ferry]

yh

I think theres way to get java to run on it but super slow

Do the cores on folia get utilised alot?

[sudden tusk]

To 'properly' run folia you basically need the latest and greatest CPU in terms of per-core power and number of cores 😆

[stiff ferry]

okay

[sturdy shoal]

which plugins support folia already

i saw bluemap having a folia build

[viral coral]

look above

[timid grotto]

...

[viral stone]

scroll up..

[sturdy shoal]

nice

[timid grotto]

i forgor to disable ping 💀

[sturdy shoal]

so fast wtf

[blissful basin]

I am no staff

So I don't care

[timid grotto]

i care 😈

[blissful basin]

Sometimes I forgot to disable ping reply for staff too and they don't care as much nowadays

[timid grotto]

if your having an active conversation, it doesnt matter, but if its "random" then it can be annoying

[blissful basin]

I like to get pings

[timid grotto]

i dont lol

[blissful basin]

It makes me feel wanted 🤣

[sturdy shoal]

why is folia much faster than paper

nvm lmao

[dreamy dirge]

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'!

[sturdy shoal]

i get why y'all don't put jars on

is it so people don't say "why doesn't this work"

[daring nimbus]

because its not production ready

[viral coral]

one of many reasons

[sturdy shoal]

and make 30 github issues basically saying the same thing

[daring nimbus]

the people who should use it at this point are able to build it themselves

[timid grotto]

if you cant figure out how to obtain a folia jar, you dont need folia

[sturdy shoal]

lmao

[livid crag]

look at the bright side. Many people learn how to compile from source after Folia

[sturdy shoal]

building is easy, ion see any point in using folia tho

[timid grotto]

#folia-help message

if your running a network or a small smp for a few people, folia probably wont be a whole lot better than paper

[sturdy shoal]

exactly

[livid crag]

Certain type of server where players are far apart and not needing complicated setup such as survival will benefit from it. Also niche use where someone may wish to have vanilla-like spawn behavior

[timid grotto]

if you are 2b2t, folia is exactly what you need

[livid crag]

I guess a very good example will be 2b2t

[sturdy shoal]

don't they still need some of their plugins to be updated?

[timid grotto]

probably, but it will happen in time

[sturdy shoal]

and i've heard the test went well

[livid crag]

I am sure they are working on it seeing that they did a test on April fool

Yeah

They don’t really have any plugin though tbf

[timid grotto]

they have some

[livid crag]

All of them are probably just to prevent exploits.

[sturdy shoal]

doubt that's hard to migrate

[timid grotto]

harder than you think

[sturdy shoal]

probably

[livid crag]

Love thier bedrock patch patch

[sturdy shoal]

just heard they have a specific plugin for a specific exploit

which is probably false

[livid crag]

That give end dimension bedrock platform

[brittle summit]

Hello can anyone help me install folia onto my server?>

[arctic tapir]

no

[dreamy dirge]

⚠️ 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.

[scenic sky]

you compile a jar file and upload that jar file onto your server

[brittle summit]

Yes but how do i compile the github files into a jar?

[arctic tapir]

read the paper readme

[brittle summit]

where can i find that?

[scenic sky]

https://github.com/PaperMC/Paper/blob/master/CONTRIBUTING.md

[arctic tapir]

readme

[scenic sky]

that has been linked before when people asked how to build

so i used the same link

[brittle summit]

This makes no sense man,

When i try to apply patches or what ever like what do i do

[arctic tapir]

you clone, applyPatches

[scenic sky]

folia aint for you currently if you cant figure out the compilation

[arctic tapir]

then run the createReobfBundlerJar command

[brittle summit]

jokni instead of being an asshole how about some help0

thats what this channel is for bud

[scenic sky]

its just how it is

[brittle summit]

if you dont need help or dont want to help get the hell out

[scenic sky]

this isnt #1083871828998635560-compilation-help

[viral coral]

read the contributing.md file

it explains it pretty well what you need to do

or even the readme.md, https://github.com/PaperMC/Paper/blob/master/README.md#how-to-compiling-jar-from-source

[brittle summit]

I applied the patches and it says it failed to apply the patches

[viral coral]

provide logs

[arctic tapir]

did yo uread it

the one about the git commands

[brittle summit]

yes i know how to use git somewhat, that reference is good to have for suree

so do i have to download the papermc jar then put it inside the file or how does this work

[scenic sky]

folia is not paper

and no

[hexed ice]

you need to set your git email and name like the message tells you to

[brittle summit]

i just did

[arctic tapir]

now do the apply patch cmd again

[brittle summit]

i did

I desperately need this on my anarchy server

[livid crag]

Do you have a 16 core modem cpu?

[inner swift]

And developers to fix plugin compatibility, unless you plan to run zero plugins

[brittle summit]

I have a dual cpu server

[scenic sky]

that is not a core amount

[brittle summit]

i know

both cpus have 18 cores

[scenic sky]

what cpu?

[brittle summit]

Xeon e5

now its saying this

[hexed ice]

did you download it as a zip instead of cloning

[brittle summit]

yep let me try to download the clone, I downloaded it as a clone on my server but not on my desktop

[scenic sky]

[viral coral]

for the like fifth time

read the README

[hexed ice]

you are supposed to clone it, not sure what you mean with downloading a clone

[viral coral]

all of your issues would've been solved by either reading your command prompt or reading README.md

[hexed ice]

too hard

[scenic sky]

pls help

[brittle summit]

hey man it looked like spanish when i was reading all that man im sorry

[viral coral]

which is why we're not distributing builds

if you can't understand basic developer terminology as mentioned in readme.md

folia is not ready

[scenic sky]

folia is currently intended for developer use

so plugins can be ported

[prime juniper]

could i run folia on a vps instead of a dedicated server?

[scenic sky]

not recommended

[arctic tapir]

no

[viral coral]

just don't

[scenic sky]

you can but its pointless

[prime juniper]

but what if the vps has many cores?

[scenic sky]

you can afford a dedi if you actually need folia

[viral coral]

you don't want to run a paper server on vps

you especially don't want to run a folia server on a vps

[prime juniper]

may i ask why i shouldnt run paper on vps?

[livid crag]

Unless your vps has ryzen 3900x or up

[viral coral]

performance

[prime juniper]

it has Ryzen 9 7950X

[scenic sky]

most vps servers perform bad

you wouldnt have very many cores with that vps anyways

[prime juniper]

it has 2 of those

[scenic sky]

just getting a 7950x dedi would be as cheap

[prime juniper]

yea

its a dedi, but i want to run multiple servers on the dedi

[scenic sky]

folia would eat up that entire 7950x probably

[brittle summit]

im doing everything y'all said to do and following this readme and im still having these errors

[arctic tapir]

send errors again

Hey guys does command blocks work with folia

[livid crag]

No and it is not planned to work ever.

[prime glen]

💀💀

[brittle summit]

its ok lol

[hexed sky]

how can i spawn entity in other dim / nether / the end

Entity entity = e.getEntity();
            Location loc = entity.getLocation();
            Vector vel = entity.getVelocity();
World world = Bukkit.getServer().getWorld("world_the_end");
                Location spawnLoc = new Location(world, 0, 150, 0);

                FallingBlock dummy = world.spawnFallingBlock(spawnLoc, ((FallingBlock) entity).getBlockData());
Vector dummyVel = vel.clone();```

i keep get java.lang.IllegalStateException: World mismatch: expected world_the_end but got world

[pseudo ibex]

Lol

[prime juniper]

anyplace one could find the limited selection of folia plugins?

[pseudo ibex]

This is a loosely built list, and is subject to change.

When the plugins that are under essential are updated, you can expect I will update to Folia. If the essential plugin are also listed under Replaceable it is both essential, but replaceable

Plugins that I have : - AutoPay, BanItem, BetterEconomy, BetterRTP, ChatFilter, Chunky, Citizens, ClansLite, CommandBlockAsPlayer, DeluxeMenus, DisableBreeding, DiscordSRV, dynmap, ElytraSpeed, floodgate, Geyser-Spigot, GlobalTrackedMaps, HarmonyScoreboard, IllegalStack, IridiumSkyblock, Lifesteal, LuckPerms, mcMMO, Multiverse-Core, Multiverse-NetherPortals, NoCheatPlus, Parkour, PL-Hide, PlaceholderAPI, PlayerBountiesPlus, PlayerKits, PlugManX, PremiumVanish, ProtocolLib, ScoreboardChatShop, SecondThreadAPI, SilkySpawnersLITE, Spark, Spleef, StackMob, StormerAntiNetherRoof, StormerAntiSpam, StormerHomesReloaded, StormerTPAReloaded, StormerWarpsReloaded, Themis, TNTRun_reloaded, Vault, ViaBackwards, ViaRewind, ViaVersion, Votifier, VotingPlugin, WorldEdit, WorldGuard

Color code - means it is a deleted plugin, means it doesn’t support Folia, means it supports Folia

Plugins so far that support Folia - BetterEconomy, Chunky, Floodgate, Geyser, GlobalTrackedMaps, ViaBackwards, ViaRewind, ViaVersion, Vault, AutoPay, Spark, DeluxeMenu, PlaceholderAPI

Essential Plugins that haven't added Folia Support - BetterRTP, ChatFilter, CommandBlockAsPlayer, DiscordSRV, HarmonyScoreboard, LuckPerms, Multiverse-Core, Multiverse-NetherPortals, PlaceHolderAPI, Pl-Hide , ScoreboardChatShop, WorldEdit, WorldGuard

Plugins that are expected to add Folia Support - BetterRTP, ClansLite, DiscordRSV, DisableBreeding, ElytraSpeed, LifeSteal, NoCheatPlus, PlayerBountiesPlus, RedLimiter, StormerAntiNetherRoof, StormerAntiSpam, StormerHomesReloaded, StormerTPAReloaded, StormerWarpsReloaded, Luckperms, WorldGuard, WorldEdit, Votifier, and VotingPlugin

Expendable plugins that could be considered replaceable and may not add Folia support - BanItem, Citizens, Dynmap, Harmony Scoreboard, Illigal Stack, IridiumSkyblock, mcMMO, MultiverseCore, MultiverseCore - NetherPortals, Parkour, Pl-Hide, PlugmanX, PlayerKits, PremiumVanish, ProtocolLib, scoreboardChatShop, SilkySpawnersLite, Spleef, StackMob, Themis, and TNTRUN Reloaded, PH-Hide.

These are the ones I have, and not all the ones out there that may have already created beta builds for Folia

Like Luckperms

[pseudo ibex]

!

[pseudo ibex]

And placeholder API

[prime juniper]

u just maintain this list? lol

impressive

[pseudo ibex]

Haha yes

[finite hinge]

Multiverse couldn't work even if someone wanted to port it, you can't load worlds right now (sounds like a major piece of work to fix)

CommandBlockAsPlayer is a no-go because command blocks will likely never be supported

[pseudo ibex]

😓

[finite hinge]

mcMMO is like, come on, ask for the freaking moon 😛

[pseudo ibex]

😰

Lmaoo

[finite hinge]

I don't even know what some of the rest are but a few of them sound like the kind of thing you pay a team to work on for a year if you want a port

[pseudo ibex]

Hahah

Some of them were custom

[finite hinge]

If you don't have paid developers on staff I suspect Folia will never be for you

Either because it won't get what you need, because you won't actually benefit from it, or because you can't afford the hardware you need for Folia be faster than Paper

Maybe in 6-24 months that changes. Wide estimate because maybe I overestimated how hard some of those are to port and because you can't really predict how long hobby stuff will take to get updated (or even if it will)

[pseudo ibex]

Haha that’s true. I am gathering a small team of people to help each other out, share knowledge and port plugins that they developed and I use over to Folia. If I do get a plugin developed, I usually request that it is posted on spigot and available for everyone.

But that is mostly why this channel exist, which seems redundant. But some people like a almost 1 on 1 feel.

😗

[finite hinge]

This channel exists so developers would be left alone in #folia-dev 😛

[pseudo ibex]

Hahaha I almost forgot this is folia help lmaooo

Well I did forget

😅

Lmaooo

😂

[finite hinge]

This is basically the overflow channel so we can tell people they can't use Folia and they can get hyped about it without cluttering up the other channel 😄

[pseudo ibex]

Hahaha

So I have noticed

Mostly All I see in this channel is please help me build folia, and the response of its in beta lmaoo

Also this

[dreamy dirge]

⚠️ 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.

[pseudo ibex]

Lmaoo

I have built folia already which is nice. Once you figure out how it is pretty nice.

[pseudo ibex]

So they aren’t supported, but do they even work?

[finite hinge]

No

They are deleted from the code

[pseudo ibex]

Do you not think if the API was developed for loading worlds it would work?

[finite hinge]

I have no idea what multiverse may or may not do when it has random threads manipulating what worlds it should be loading and the properties of them

Probably bad things

[pseudo ibex]

Wait so I can’t even spawn them in? ( haven’t tested it )

[finite hinge]

iirc you can place the block but the tick method is commented out

[pseudo ibex]

😗

[pseudo ibex]

Oh ok, so if command block as player is ported over, and it just uses other plugins to active commands as a player it should work?

🤔

[finite hinge]

Err, that's called just writing a plugin to run commands for you

I think that's called Skript

afaik command blocks cannot save commands in them, they will not run them when powered (or however else you activate them), and they will not output a power level based on the result of the command

The power level output part is the least likely to ever actually happen and without it the rest is kind of pointless

[pseudo ibex]

Fair

And makes sense

Wouldn’t even register, even with such a thing it sounds like

Why was it removed from the code?

Causing problems I presume?

Or ancient ?

[finite hinge]

You put in a command that runs on all players or all bats, before that was no big deal, just a quick loop. Now that's scheduling tasks on all the relevant region/entity schedulers and they'll get to them when they get to them, the command has no (immediate) feedback available

So it can't output a power level

[pseudo ibex]

😳

[finite hinge]

Beyond that I don't know why command blocks were disabled, I just know why that part can't work

In theory you could check which things you could run on the current region thread, run those immediately, then block this region waiting for the others to finish but I can think of at least 3 ways to deadlock regions or the whole server trying to do that

[pseudo ibex]

Hmmm in theory, I suppose I should test this.

[finite hinge]

I don't know if you could implement it at all but even if you could you couldn't make it safe to actually use

[pseudo ibex]

Why’s that?

[finite hinge]

You would need some way to basically collapse the world back down to running a single region while the command block is running

[pseudo ibex]

Oh that sounds complicated quick

I was thinking it would be, simpler lol

[finite hinge]

Otherwise if two command blocks in different regions run a command that crosses regions at the same time they'll block each other from ever completing and you have two dead regions

Or you might manage to block the ThreadedRegionizer if it was trying to merge a region that is blocked like that, not sure on the specifics of how that lock works

At that point you've killed everything

[pseudo ibex]

Hahhaah

[finite hinge]

Collapsing the world down in to one region isn't possible either for the same reasons

[pseudo ibex]

How interesting

But informational

[finite hinge]

If two command blocks in different regions trigger that logic at the same time neither will be in the right phase of their tick to be mergable but both are waiting for the other to merge with them

So yeah, forget about command blocks

[pseudo ibex]

Hahaha

[pseudo ibex]

Huh. Also you said bad things, if I got a plugin developed to do this what’s the worst that could happen if I could get this to work?

[finite hinge]

I think Java is a little nicer so it's not allowed to literally make your computer explode or delete all your files

[pseudo ibex]

😂

So nothing to bad?

[finite hinge]

https://docs.oracle.com/javase/specs/jls/se10/html/jls-17.html#jls-17.4

Incorrectly Synchronized Programs May Exhibit Surprising Behavior

[pseudo ibex]

Hmmm, so I shouldn’t even attempt this unless I have a team of pros?

[finite hinge]

It's kind of wild to me that the most important document in computer programming written in the last 20 years is just wedged in the middle of the Java spec page about threads and locks

[pseudo ibex]

It is what it is lol

[finite hinge]

The C++ and Rust memory models are based on the Java Memory Model and the JMM is generally how people think about and discuss thread safety and threading primitives

[pseudo ibex]

Hmm integral to this goal. Go on?

Or is that it lol? Whatever the case, I will take note of the information given so far.

Thanks (:

[prime glen]

💀💀

[finite hinge]

The only other thing I really have is this (that's a standing desk)

[prime glen]

Just yetted commandblocks out of existence

[pseudo ibex]

I am assuming this isn’t your exact desk, unless you are kinda bald. But nothing wrong with that 😄

Show us a pic 😗

[finite hinge]

Nah, that's https://dbaron.org/ and he put the sign up
