Did you clone it or just downlload it?

sonic kayak
#

download it

viral stone
#

read the paper compilation instructions, looks lke you forgot a step or something

Suggestion: Global Entity Scheduler

inner swift
#

What's the use case for this

viral stone
#

seems entirely redundant

sudden tusk
#

What would it do?

finite hinge
#

It would delete folia.jar and download the latest paper build

night stone
#

Can I safely use Folia for servers without major risks? Or well, how safe is it compared to Paper?

#

Crash-wise and stability etc.

frank prism
#

its so experimental that right now you are discouraged to share builds of it such that only people who are smart enough to build it themselves can use it

finite hinge
#

There are a few known limitations and issues and none of your plugins will work

#

Depending on what kind of server you run those limitations can be showstoppers

@primal quail I have a feeling leaf was judging they crashed based on their tick rate or people in them getting disconnected or something. Or maybe from an error stacktrace in the console? I don't remember seeing anything that specifically marked a region as dead but there is a lot of code in there and I was just skimming so... maybe

MSPT just went up to when a region crashed, so you have like 20k mspt in /tps kek

celest forum
#

imo that was my favorite part about testing folia

#

kind of hard to make the entire server crash

#

just a single region crashes

#

not really crashes but hangs

ivory dust
#

Anyone know a claims plugin that works on folia?

finite hinge
#

PR-Tree is not thread safe so you'd have to do some kind of per-region cache

#

(for WorldGuard)

#

Hmm, although that would require WG knowing how large the regions are (and when they change size) so it knows what to store in each

#

I suppose it changes so infrequently you might be okay just copying it fully into each region and updating the copies whenever something changes

Hey devs, I’ve got a 8 core (rk3588) single board computer with 4gb of ram (orange pi 5) Currently running on Bukkit without any plugins, and seems like almost always a single core is struggling quite hard. Would running folia be beneficial performance wise? Maximum 10 players space fairly out on survival.

What possible problems will the installation of foila contain?

#

hi

viral stone
#

it's pre-release experimental software

#

issues range from crashes to setting your cat on fire, to weird state issues

foggy scarab
#

OK, I know, but don't the plugins have any special problems to work?

#

😶

viral stone

plugins need to specifically support folia

#

Please see the readme, etc

#

What scheduler should I use for delaying the spawning of particles?

foggy scarab
#

I read GitHub. But I want to know if it does not specifically support it. Does the plugin fail?

Is there any information so I can find out what plugins are supported?

I actually wanna do this for funsies, how do I convert these .patch to the source? I'm assuming that's what you'd do since there's no source anywhere? I'm not used to Kotlin nor Gradle so I'm totally fish outa water rn lmao

#

I don't plan on actually providing any jars, I'll prolly delete the .bat files too so people don't actually try to compile

viral stone

you apply he patches and then modify i was per the contrib guide

so true

Anyways, it was more of a heads up than anything, if you get weird requests about Folia, maybe its cause hosts want to start offering it. However, the option to set it up as my server was buried ( I am experimenting with pebblehost) so maybe people wont see it?

oak gull
#

ah if it's hidden to normal users, should not be a worry

it's in the "other" section

The reason why 16 is picked is on the readme.

Finally got some screenshot

So the Dog teleport on top of the water and walk normally while ignoring the gravity and it reset as soon as he touch the sand

can you hit the dog ?

I can try but it will probably take time

#

First I need to reproduce the bug and then the dog walk fast, so need to keep it in buggy state long enough

tawdry merlin
#

Well, I was trying to force trigger the bug by being surrounded by water but here, the dog don't even teleport to me

2023-04-18_20.33.38.png

(it's at the end of the cobble)

I'll see if it happen to punch it and see if it fall down or stay on the air if the bug trigger again

dog teleportation is very dodgy in general. Have you tried it on Paper?

#

I'm so stoked for Folia

#

However, my plugin may never see the light of day on Folia unless there's some reasonable port system. Just diving into this, is there plans to allow legacy plugins?

scenic sky
#

0% of them would work

bold igloo
#

Probably a bit early and may just require a rewrite of Heroes to get on Folia

finite hinge
#

Putting in a compatibility layer would turn Folia into a slower Paper

bold igloo
#

Didn't consider that, you're right

#

Its my dream to host a server that isnt limited by the main thread... and I guess in a way I will need to have a full rewrite of Heroes no matter what

Will Patina be better than this core?

viral coral
#

patina should be avoided at all costs

#

nor is it similar to folia, it's just a paper fork

vivid tinsel
#

Never heard of patina until now

viral coral
#

it's yatopia's successor

vivid tinsel
#

And judging by you saying to avoid it, it’s not all that good

viral coral
#

yatopia is advised against by practically any notable plugin developer

#

highly volatile

#

unstable

mystic shard
#

I watched the video, she was the best there. AirPlane was also in the top 2.

scenic sky
#

airplane has been discontinued for like 2 years

mystic shard
#

OK, I didn't know. And then what is the best core? For version 1.16.5

scenic sky
#

my recommendation would be to not use 1.16.5

viral stone
#

This isn't the place for discussion around random software, especially unsupported versions

mystic shard
viral stone
#

the only recommended/supported software here is paper, unless you have a more niche usecase; but, given you're using an unsupported version, you're generally on your own in any case

scenic sky
viral stone
#

Because it's unsupported, unmaintained, and has known exploits

pulsar sentinel
#

I assume I am going to have to set JVM arguments to determine the cores and threads used, right?

#

Because currently I have it at
-Xms24G -Xmx48G -XX:ConcGCThreads=16 -XX:ParallelGCThreads=16

viral coral
#

that doesn't set cores/threads for folia

#

that's just garbage collection

pulsar sentinel
#

Ah, then isi it automatic or..?

viral coral
#

yes

pulsar sentinel
#

Oh cool!

viral coral
#

pretty sure it can be configured in paper.yml if you need to override it for whatever reason

pulsar sentinel
#

Okay, If thats the case then I think there should be a thing in the console that states the amount of threads and cores used before everything loads up, it would clear a lot of confusion on my end

#

Wait what, there is no paper.yml

tawdry gullBOT
#

Where did paper.yml go?

In 1.19, paper.yml has been split into two files, both in the config directory. In paper-global.yml you will find configuration that changes behavior of the whole server, and in paper-world-defaults you will find configuration that can be overridden on a per world basis. See https://docs.papermc.io/paper/per-world-configuration for more information on overrides. The function of server.properties, bukkit.yml, and spigot.yml remains unchanged for this time.

pulsar sentinel
#

Oh! It's all there, thanks

No one has been able to nail down what causes gradle to forget it has a working JDK sometimes

#

It happens on Windows and Linux

#

The fix is usually to install another one

Someone was sharing a patch a few days ago that forced gradle to download a new JVM for building, because that's a thing gradle can do these days

It is but the check is faulty

rapid acorn
#

nice :)

image.png
#

experimentally it seems i need to be 5 mc regions away for folia to actually split the regions

#

(this is with setting a bunch of blocks at the world origin and then just flying away)

#

is there a way to make that smaller?

scenic sky
#

folia isnt very viable if you make it smaller

viral stone
#

splitting up harder makes the system overall have to do more work

#

afaik, it's also not tweakable as it's somewhat ingrained into the math/logic a bit

finite hinge
# rapid acorn is there a way to make that smaller?

Leaf described it as view-distance 10 means chunks in a radius of 11 around a player will be brought to full loaded which is ticket level 33. The system will create chunk holders up to ticket level 45 (apparently in a flood fill manner) so it touches an extra 13 radius out from there for a total of a 24 chunk radius. Current region section size is 16x16 chunks so that fits in 2 sections. Then the regionizer creates an empty section around non-empty for buffer so you get 3 sections, 48 chunks, or 768 blocks

#

So players have to be more than 1,536 blocks (768*2) away from each other to be in different regions but the server won't immediately split a region either

#

The only way to get less than 768 would be to have a view-distance of 2

rapid acorn
#

okay, i'll try with view-distance 1

#

oh whoops

image.png
finite hinge
#

Yeah I didn't expect it to actually work below a view-distance of 3 😛

#

I don't even think Paper does

#

If sections were 8x8 instead of 16x16 view-distance 10 would end up with 512 blocks (or 1024 between players)

#

Dunno how feasible that is

#

The next big change would be to get the chunk system to stop getting tickets out to level 45

rapid acorn
#

but the regions aren't quite splitting at 1536 distance even after sitting here a while

finite hinge
#

It doesn't aggressively split them

#

I think you have to get another 3 or 5 sections separated before it'll split?

#

1536 is just when it'll merge them because they ran in to each other

rapid acorn
#

ah yeah that makes sense

finite hinge
#

If it instantly split them you'd have flapping

rapid acorn
#

teleporting between 1536.5 and 1792 seems to have it merging and splitting them fairly consistently

#

1664 is in the area where it won't merge nor split

#

i realise all this experimenting is probably useless if you actually understand how the regionizer works

livid crag
#

Read the readme part of folia

#

It has detailed instruction

gilded blaze
#

I assume Folia has no issues with handling large amount of worlds? In general working with worlds is pain but it seems good way to separate player islands, especially on folia where we don't really need to unload & save those worlds as server is likely to hold big amount of players.

scenic sky
#

dont think folia actually supports more worlds than the 3 default ones currently

gilded blaze
#

oh, didn't know that

scenic sky
#

i think support will be added some day, no idea when

gilded blaze
#

yeah understandable, looking forward to it

bold osprey
# gilded blaze I assume Folia has no issues with handling large amount of worlds? In general wo...

working on such support, and already have a production skyblock server which gives players own overworld, nether and end

about the lags, only the region amount can cause kind of additional load, but if you disable keep spawn loaded, the world by default won't have any region, so it won't have anything to tick in terms of region

other part is time tick, which is on global thread, i don't it will ever be something to worry about, but it can if you'll have too many worlds, it won't impact gameplay, since it won't impact any region thread, but players could have to wait longer to join the server and time (day/night cycle) can go slower

gilded blaze
#

Good news, thanks for updating me on status of this feature

bold osprey
#

and when talking about too many worlds i would say more than a few hundreds of thousands, but may be even a few tens of thousands enough for lags

gilded blaze
#

Yeah will never hit that amount anyway, I'd run out of storage before having this many islands

bold osprey
#

another part is that world load/unload will have to be done on global tick thread, so loading/unloading too many worlds can also cause issues, if you wait enough after player left the server the regions should be destroyed and it shouldn't be a problem, otherwise it may cause issues on too many loads/unloads

#

but also, the worst case scenario, players will wait longer to join, if they just play they won't feel something

gilded blaze
#

Yeah that's not big of a deal don't expect big traffic. So loading takes place in main tick loop but gameplay not hence only joining and other operations handled in main loop would be affected?

bold osprey
#

there isn't such thing as "main loop"

#

each region are independent and can run in parallel

gilded blaze
#

Oh so folia got completely rid of that "parent" loop?

bold osprey
#

yes

gilded blaze
#

What about connections, they're handled on netty threads until player gets spawned in world?

bold osprey
#

starts on netty, then global tick thread, then region in which they are

gilded blaze
#

ah so there's a global tick thread - that's where loading worlds is handled too right?

bold osprey
# 
     worldborder tick
     advancing the weather cycle
     sleep status thing
     updating sky brightness
     time ticking (game time + daylight), plus PrimayLevelDat#getScheduledEvents ticking

that's global tick thread's main purpose

gilded blaze
#

oh okay well I think it makes sense for me now, perhaps it iterates through all worlds while e.g. advancing weather cycle and thats why it's likely to cause delays with huge amounts of worlds?

bold osprey
#

but also

ticking some connections
handle console commands
refresh player sample from server list
update tab

bold osprey
gilded blaze
#

understandable, I just wanted to get things right because folia is pretty non-standard approach to server software design (at least not something we were used to)

#

thanks for your time spent on explaining me this 😄

bold osprey

no problem 👍

twilit bison
#

Howdy! I'm very excited to see if Folia will improve my lag that seems to be a consequence of my absurd stack of custom function scripts that constantly attempt to track entity states. What do you think?

scenic sky
#

folia isnt a fix for heavy plugins, but it might help

daring nimbus
#

Folia doesn't support datapack functions and likely never will

twilit bison
viral coral
#

if you want to fix your performance issues

#

remove datapacks

twilit bison
#

I built this datapack myself. It's a custom design.

viral coral
#

functions are terrible for performance and i doubt folia will care about them any time soon

#

datapacks aren't really something people care about when running minecraft at scale

twilit bison
#

I guess I was hoping that function scripts would get threaded. What a pain.

#

I built an entire interactive RPG system on function scripts, trying to avoid all types of mods and doing it just in vanilla. It works, but it runs like ass. :c

viral coral
#

that's datapacks for you

#

you'd be more likely to find a fabric mod that optimizes functions / datapacks

twilit bison
#

The end goal was always to have something that requires no client mods. Hmm...

viral coral
#

fabric does not mean you need client mods

#

fabric runs serverside aswell

twilit bison
#

Yeah

#

How the hell does Origin Realms do it? I'll never figure it out...

daring nimbus
#

definitely not datapacks

viral coral

#

#

#

viral coral
#

weak tundra
#

#

That's the ways you can get text onto the main client screen

#

Now which are you referring to

viral coral
#

people don't use the chat for that

#

nor tablist

twilit bison
#

Oh, the clock and whatnot.

viral coral
#

the clock is a boss bar since it's aligned to the top

twilit bison
#

Yeah, I worked that out after you mentioned.

#

Marvelous work.

#

I've spent the past 10 years of my life fiddling with Minecraft from a vanilla-adjacent view. I dove deep into function scripts after nearly blowing up my server with command blocks before early datapack concepts started coming out. I've been using a custom datapack to tweak and automate tons of interactions with entities to make all sorts of mod-like behavior without the mods.

Our server was basically murdered by the Bukkit DMCA apocalpyse back in the day, so we swore off server mods until they looked like they were keeping up with vanilla releases.

I've noticed that projects like paper and fabric are keeping up pretty well since deobfuscation happened. I am still afraid of server mods because reliance on these systems has burnt us several times over. It's a weird position to be in, talking to you nice folks and your impressive project.

viral coral
#

there are server businesses relying on paper that earn literal millions per year / per month

#

if they can rely on using paper or some other project

#

you can

#

it is absolutely still a gray area of how it all comes together but mojang is more than aware of the modding scene and how it works and there's a seemingly positive relationship so shrug_animated

daring nimbus
#

and when the worst happens, fork Paper and keep a fork going

twilit bison
#

Meanwhile on my Spigot server, just standing still as the only player on the map...

s behind
[XX:59:32] [Server thread/WARN]: Can't keep up! Is the server overloaded? Running 5685ms or 113 tick
s behind
viral coral
#

that's to be expected when running spigot

twilit bison
#

lol

daring nimbus
#

but, if you want to do an RPG type of server you should really look at plugin or mod development. Doing that with datapacks and function is needlessly hard, and will also perform badly. And there isn't really that much optimisation potential there, java code will always run much faster

#

And even if you spend a few months learning Java and need to take a break from the project because of that, its probably worth it in the end

twilit bison
#

I kinda finished it already and developed custom web tools to generate the function scripts on the fly and...

viral coral
#

kek

#

build a function to java compiler

twilit bison
#

:\

bold osprey
#

so yeah, really many ways

twilit bison
#

Advancement editing is fun. I use mainly :impossible and trigger quest progression via entity interaction that triggers function scripts with commands that complete the advancement (whenever predicates aren't good enough)

#

Anyway, this is getting pretty off topic. Thanks for letting me know that Folia doesn't have any investment in function scripts or datapack stuff as a whole.

bold osprey
#

well, it was known that functions are laggy for a long time, never used a datapack that contains functions (we have datapacks, but no functions), and since folia is for servers with big player amount (for small servers it may be even worse than paper in terms of performance), so it's a bit logic that something built with only performance in mind won't add support for something that will 100% be laggy

inner swift
#

It's more about the state those commands expect

twilit bison
#

They are 90% target selectors and execute commands, so I guess that's it.

#

I've worked hard to localize execution to a radius around a player and whatnot, to be as efficient as possible. It worked well until I started scaling up, of course.

#

Again, i'm pushing too much off-topic. I'm just grateful that anyone is talking to me about this.

knotty hemlock
#

Hi everyone👀

#

I was wondering what would happen if Folia had opened up function instructions, because I had tried to get a packet that required a lot of function instructions to run on Folia, and it ran, but soon my server crashed - because all his function instructions failed haha

idle furnace
daring nimbus
finite hinge
#

Even if they could run they wouldn't work right due to commands not having their vanilla return values

#

Although that's not as untenable as command blocks I guess since the global scheduler probably can block all the regions to process commands

#

Now you'd have to have two versions of every command though: one that makes the server slow and one that breaks vanilla compat

#

That's a lot of work to get vanilla compatibility with something plugins can do better, especially since you'd get better performance running such a setup on Paper anyway

Would be nice to have some sort of list of plugins that are known to be compatible with Folia. Perhaps a list of important/well renowned plugins that aren't.

Hi there! I testing Folia on my own home server (two xeons e5-2696v4, 64 gb ram, OS windows server datacenter edition), i'd like to know answers the some questions:

  1. minimal region size, which Folia may support (500x500 or 1000x1000, or something else?)
  2. recommended jvm flags for Folia?
daring nimbus
#

If you scroll up here a bit, there will be some explanations about the distances between players that are required for two regions to exist. 1000 blocks won't be enough.
And the usual flags used for Paper are probably fine, but there hasn't been much testing done. Keep in mind GC needs threads too when setting up the rest tho

And not throgh the datapack as is or the items in your hotbar

#

Nope, I think this may be caused by folia, because I also tested it on the original paper server without any errors or problems ...

#

Of course, this is just a packet with modified vanilla terrain

subtle adder
#

i dont know how supported this stuff is on folia currently

knotty hemlock
#

But what makes me wonder is why only this ocean has a chance to trigger this bug and not elsewhere, you can check out my issue

#

too strange

#

But understandably, after all, Folia is still in a very immature development period, and I would like to use the early Folia to report problems to Papermc and Folia's plugin developers

finite hinge
#

I'm assuming packet means datapack

#

Packet normally means the things the client and server send to each other

#

I wonder if it's something with a really big structures breaking folia's region invariants

#

Does your structure datapack make anything really large?

#

I would think that would just make Folia throw exceptions and die though, not scribble garbage over the world

knotty hemlock
#

only these datapacket

#

It worked just fine on my previous Paper server

#

You can try it on your server or minecraft

#

The main thing that puzzles me the most is why I've made Paper load normal blocks, and I copy the normal block file to the Folia server and he still loads incorrectly, which is not just a packet problem, at least that's what I think

inner jolt
#

What is the goal of folia ? What is the difference between paper and folia

hexed ice
#

Have you read the folia readme / docs?

inner jolt
#

Im reading it on paper website

bold osprey
#

a bit of tl;dr for readme

keen fable
#

if you load a region file on Folia (without any plugin/datapacks) and it is not the same as Paper you should report it

fair merlin
#

@cosmic pawn Replying to you here because it's more of a general question than a dev question, but Folia is a different project with different goals and approaches than the other servers you mentioned.

Leaf started work on it a few years ago (2019/2020?) and probably had the idea longer than that.

#

But Leaf is always looking for ways to optimize Minecraft and Paper especially, with Starlight, the new chunk system, etc etc. So to him this seemed like something doable.

cosmic pawn
next bloom
#

Folia provides benefits for players that are not always in the same place. So a large survival server with a very large world border is a good candidate.

#

Things like MultiPaper were/are trying to increase performance for a bunch of players all in one area

fair merlin
#

AFAIK no one has done a test with 1000 players yet, so TBD.

viral stone
#

I mean, see 2b2t

cosmic pawn
#

And how accessible will this new server implementation be to more amateur server owners.

viral stone
#

it's not

viral coral
#

not

#

your amateur server owner probably won't have the hardware for it

viral stone
#

us paper devs theorised on a lot of this earlier, just we wanted to try to avoid the API breakages, and it was not as much of a priority given how much work i is

cosmic pawn
#

When i say amateur I mean guys who rent a hetzner machine and have like 100 player servers but not giant servers with employed devs and stuff

fair merlin
#

You need expensive hardware to take advantage of it.

viral stone
#

leafs work breaks a large chunk of how the API works, which from our analysis fixes a lot of concerns at the cost of making the entry point much higher

fair merlin
#

So it's probably not realistic for small servers.

viral coral
viral stone
#

Given that it breaks the API behavior, it requires on plugins to be modified for it

cosmic pawn
viral stone
#

While some plugins, Essentials, etc; may update, the reality is that 99% of plugins are not going to give a single care about Folia

fair merlin
cosmic pawn
fair merlin
#

It's really built for servers with a lot of cores.

viral stone
#

the work required to split up the world into chunks is not exactly cheap

#

Running parallel loads also generally requires you to have plenty of CPU cores to actually justify that work

cosmic pawn
inner swift
#

(Since you mentioned Hetzner, have a look on their 7950x3D ones)

cosmic pawn
fair merlin
cosmic pawn
#

So the type of CPU you want is different

viral stone
#

both are relevant

#

at the end of the day you still essentially have mini servers ticking in the name of regions

#

how much the balance between single core performance and CPU core count is going to vary depending on what's going on

sudden tusk
#

It's about having the most over the top number of cores while every single core is very powerful 😆

cosmic pawn
#

right. Which CPU that's on the market do you guys think will be best for Foila?

#

or like what type of CPU

viral stone
#

There is no "best", it depends on the load factor

#

if you actually have a bunch of dozen players spread out, then an EPYC is generally going to do a good job

#

if you have players who are going crazy with redstone, etc, that's probably going to become an issue fast

cosmic pawn
#

right ok that's what i was trying to get at

inner swift
#

(Intel's E-cores won't do it, btw)

cosmic pawn
#

I imagine having limits on redstone and block entities will still be necessary in Folia servers

fair merlin
#

We ran ~320 people concurrently. So if you want close to that you want a 7713 or better.

#

As I said above it's really more for higher end hardware. You want a lot of threads and a lot of RAM.

cosmic pawn
viral stone
#

dual socket

cosmic pawn
#

oh damn

#

this is some industrial grade stuff now

fair merlin
#

We had 2 7713s, yeah. Server we rented wasn't available with just one.

#

And NUMA is questionable for this so we disabled one

cosmic pawn
fair merlin
#

We could have had more. That was just all the people we had join.

#

Again, all of this info is in pins in this channel .

#

There's even an FAQ I wrote up :)

cosmic pawn
#

how do i get pings for folia

next bloom
#

I don’t think there is a channel or role for that

near crater
#

I forgot how much 2b2t pushed with it. Was it almost 600?

#

Yeah I clocked them at 610 players online at once at the peak.

jovial helm
#

650 ish

daring nimbus
#

noticeably without pre-genning. But outside of exploring new chunks it was very playable

keen fable
#

another use for Folia, besides its ability to receive a large number of players, is that lag is regionalized, meaning that admins can allow players to build large lag-machines without worrying about other player performance

it might be a good option even for small 100% vanilla servers of 20-50 players.

fair merlin
#

Because of the way Folia is written, it just needs more threads to run.

#

So you would probably still need much more / expensive hardware to run 20-50 players on it than you would Paper.

bleak oar
#

hi guys, is there any stable protocollib version that supports Folia ?

fair merlin
#

Good question. Probably best to check with ProtocolLib

bleak oar
finite hinge
#

The protocol supports things vanilla doesn't use so some of the packet classes in there are annoying or impossible to use for some things

bleak oar
#

mob/item stacker

finite hinge
#

You're assuming I know what's involved in doing that and know all the bits that are missing from the packet constructors and getters/setters 😛

#

I'm just saying, don't be surprised if you end up in reflection hell or just writing your own raw bytes to the socket at some point

bleak oar
#

will be probably easier

#

and better

#

btw I have a question, why not using fibers (virtual threads) for Folia ?

viral stone
#

because they don't exist in the LTS yet, and generally aren't beneficial outside of certain cases

bleak oar
#

Ok thanks

finite hinge
#

If you have N cores and spawn N*2 threads the OS will keep them balanced. If you spawn N*2 virtual threads you'd better be doing a lot of IO in them otherwise half of them will never get to run, the OS doesn't know they exist and the JVM uses cooperative multitasking for them, switching between them when one is blocked or finished

bold osprey
#

yeah, i think they would be great for things like mysql connections and for netty to use them

maybe for some servers would be beneficial for async scheduler to use virtual threads, since i saw that lots of plugins just does blocking operations on async scheduler, and since async scheduler is based on executor service, it likes to spawn new threads, so we have lots of sleeping threads being blocked while executing a plugin task

finite hinge
#

The problem is some people really are doing CPU heavy work in them so instead you need another scheduler

bold osprey
#

maybe better a config for that, because if they would support additional scheduler, then they probably would support the threads directly

finite hinge
#

iirc go has some logic to put in a sleep call after so many function calls to ensure a long running goroutine shares with others but even that doesn't help if you're just spinning in a loop doing a lot of expensive work

#

I don't know that the JVM even has that

#

The thread has to be blocked or sleep (which is sort of just blocked, I guess)

#

A config wouldn't make sense, if a plugin does a lot of IO and has some CPU heavy work to do you're just forcing them to spawn their own real threads

#

So now plugins are back to setting up their own thread pools and such and stomping on each other

#

Or if all your plugins are only doing IO you turn on the config for a minor perf win then later you add a plugin that does CPU heavy work and it kills all your other plugins

bold osprey
#

still not guaranteed that a server has those cpu intensive tasks, i remember that all those were in separate threads made by plugins, i don't remember seeing cpu intensive tasks on async scheduler

#

but instead having 300 sleeping threads

finite hinge
#

Sure, then you install dynmap 😛

#

Having it be a config is just a footgun

#

Better to have a separate scheduler or just have plugins do virtual threads on their own

bold osprey
#

yeah, because most probably some will start to recommend this config as "super performance performance improvement from paper, enable right now"

finite hinge
#

Absolutely, and it'll be a minor perf/memory win (not even worth mentioning) 99% of the time, 0.5% of the time it'll make a noticeable improvement, and 0.5% of the time it'll wreck things

#

Your OS doesn't have any problems managing thousands of threads, it's just memory

#

Tens of thousands is doable but maybe you should consider alternatives, more than that and you're going to have a bad day

#

Well, assuming your OS is Linux but you're running a server so of course it is

bold osprey
#

on paper it already almost don't uses the scheduler, since even chunk loading is async, not like before

finite hinge
#

It was an example

#

It's a CPU heavy plugin that keeps off the main thread

knotty hemlock
#

so I think this is a Folia's bug

fair merlin
#

I think Leaf hates virtual threads.

#

But he hates a lot of things.

Hi Datapack is not supported?

knotty hemlock
maiden jay
#

ok, thank you

severe dew
fair merlin
#

Command blocks not likely.

bold osprey
fair merlin
#

Datapacks probably not likely.

bold osprey
#

even though command blocks maybe, but with reduced functionality (to just run commands without storing result), datapack functions don't think that ever will be supported

#

because they depend too much one 1 thread as i know, they can't be compatible with multithreaded core

#

and functions are really laggy, if you use them, then probably won't need folia

primal sluice
#

Hi, I'm a little confused about the functionality between /paper entity list vs /tps, I have 1 region, and it's reporting that there are 1569 entities within that region.
However, when I run /paper entity list, I only see a total ticking of 124 and 11 non ticking. I was wondering why these two values don't match up?

echo widget
#

I have a server with two cpus (the OS reads the logical cores of each CPU together into one aggregate CPU) will I be able to use Folia across both CPUs

bold osprey
fair merlin
#

You're also probably gonna run into a lot of plugin issues when you have more than one CPU accessing memory.

echo widget
#

I mean for the operating system it is "one cpu"

bleak oar
#

does velocity/bungee plugins will work as normal ?

fair merlin
bleak oar
#

but how can a different fork impact a plugin running on the proxy ?

fair merlin
#

If the plugin is only running on the proxy and not talking to the server at all it's probably fine.

bleak oar

ok

I'm working with my univeristy, and they want to use Minecraft as a teaching tool, but to actually make it work while, its going to have to handle at least 300, which may be able to be done on regular paper due to the fact we won't need entity spawns and shit like that

However, I also feel Folia would scale much better

This is getting on my nerves, i have compiled like 10 times now. And it's not compiling the correct thing, even tho i download a fresh batch from the folia github

Anyone, that's able to send me a working jar file in a DM

livid crag

Folia in its current stage is for experienced developer only if you are unable to compile even a jar file, the chance of you needing to use such project is very small. wait for official release and continue to use Paper instead. **We strongly discourage sharing jar files. **

@loud schooner so if you run the build again, do you get that SHA1 hash mismatch again?

can you open that downloadServerJar.jar file using https://hexed.it/ and screenshot it

cause for whatever reason, that file is something other than a jar file

hmm can you build with --stacktrace again and post that log

I wonder if this is spuriously failing and maybe giving a different error each time, cause your log said "failed with exit code 137" but that does not look like the output of a failed decompilation

#

oh wait

are you building as root?

loud schooner

yes?

sonic scaffold
#

make sure you're not building as root, because I see your gradle cache in /root/

#

root = all sorts of problems

loud schooner
#

😂 OK

sonic scaffold
#

building as root may have damaged the permission bits on your build files, so run something like sudo chown -R lordpipe:lordpipe ./Folia but with your username to restore it to normal (or clone the repo again and start from scratch)

loud schooner
sonic scaffold
#

I think other parts of your home directory (/data?) may have gotten infected by root permissions

loud schooner
sonic scaffold
#

you should probably just take ownership of /data:

sudo chown -R shintokosei:shintokosei /data
``` (there are more nuanced ways to have a folder managed by multiple unix accounts if needed, but this will do for now)
#

for a full reset of everything:

# only running this as root because it might have been infected by root permissions
# normally, don't use root for anything build-related
sudo rm -rfv ~/.gradle ~/.m2
sudo rm -rfv /data/Folia
sudo chown -R shintokosei:shintokosei /data

it was out of memory error the whole time, somehow I misread 137 as 127 every time I looked at it, which made it seem a lot more mysterious than it actually is ._.

#

you'll need some swap space to be able to complete this build

to create swap space without having to reboot:

sudo dd if=/dev/zero of=/swapfile bs=1M count=8192
sudo mkswap /swapfile
sudo chmod 0600 /swapfile
sudo swapon /swapfile

this will act as overflow RAM for the build to be able to finish

Is there currently a way to alter folia or plug ins so they are conpatable with each other?

I need to download folia to test it, is there any method or something to do to obtain it? Or is it already implemented in Paper?
