still need the chunk-loading section in my 1.18 world
cant handle more than 110 players
In December.
and we don't owe anybody our time
I hear Paper is an open-source project that anyone can contribute to
if you have a patch you'd like to see updated, you can always have one of your developers spend some time on it and test it in your environment
I'm on 1.18.1 and there is no fix-curing-zombie-villager-discount-exploit in the paper.yml
How can I fix this?
Should I just add it?
It's 100% in there
Why is the thing on paper orange now not red. Does that mean it’s stable, a glitch, getting there, just progress? Sorry I’m confused
well
Still experimental. Take backups, use at your own risk.
orange is less dangerous looking than red
paper.yml by @lavish jolt: https://paste.gg/12b6c4f6be3b40af9b798972d7ce2167
1.18.1 There is an issue with portals creating new portals after updating from 1.17.1 Is paper aware?
where can I find the issue tracker? is it on there?
(that was sarcasm, btw; you'rerunning early builds, you should be checking this stuff...)
on github
I'm on #68? its not an early build?
these are still early builds in general.
do you have a link please ..to github issue tracker?
thank you
then see the paper repo and go to the issues tab
paper repo?
yes
there is a link to our org on there
then you click Paper
then you go to the issues tab
ahh I found the paper github link ..couldn't find 'repo' so I was confused
Did it get downgraded then? The original/recommended was a 10/10
That's what apache said
But redhat said 9.8
I didn't see the official one, didn't had a score last I checked
I was assuming apaches 10 was a placeholder
Yeah official site still has no score
I realize this probably doesn't have anything to do with paper, but I was just curious if anyone else was having issues teleporting in spectatormode in 1.18 vs 1.17?
Not myself
I believe it's more related to Geyser or BungeeCord, i'll go inquire elsewhere; as it affects not just 1.18 servers but also 1.16 ones on the same network
Geyser 
how do i fix the anti xray in the nether?
Anti Xray configuration guide: https://gist.github.com/stonar96/ba18568bd91e5afd590e8038d14e245e
did you read the guide?
You need to create a new section for your nether world
glad to see the paper discord hasnt changed since I last joined
is it still on expriement?
yes.
thats at least 6 months out still, unlikely
this is my feelling litrally anyways have fun and great job still i know the troubles and i iappreciate u guys
I know there isn't any ETA on when a "stable" release will be finished, but how "stable" is the current build? Do we know kind of how common bugs are and how severe they are atm?
I have a small server of just like 6 people but I'm itching to go up to 1.18 lol
there aren't any big bugs that have been reported as of yet
just make sure to take a backup from before you update, and then take backups somewhat regularly in case smth goes sideways
Ok, good to know, thanks.
It’s less about bugs and more about patches that haven’t been ported to 1.18. The big one being no tick view distance
Not sure if it's a paper bug but iron golems seem to be spawning on slabs and inside stone fences when built into a farm
So with this exploit, If you have a whitelist active, would someone be able to try to connect with the exploit as their name or something? Because that gets logged when someone tries to connect.
yeah, for now Essentials, GriefDefender, WorldEdit, I'll check later for the isssue without any plugins enabled, when there are fewer players online
Yes, so update.
whitelist wouldn't matter, all join attempts are logged
If you put leaves on top it should prevent them from spawning
https://timings.aikar.co/?id=6e699c44adf04c8192ef7597a299bf1e it looks okay? What do you think?
Aikar's Timings Viewer - View Timings v2 reports from Paper and Sponge
Gotcha, gotcha. I'm all updated with the flag added, just curious.
It's also been spawning on a slab-only idle platform with a chest nearby
I changed the color from orange to green - are they safe to use now?
(I'm joking btw, don't ask for etas or you will be fed to goblins)
Doesnt seem to be happening in singleplayer so far
Yes
What do you mean by no tick view distance? Not familiar with the behavior, would you mind explaining?
view distance in 1.18 is the same concept as no-tick view distance
the chunks are loaded from file and sent to players, but not actually processed server-side for entities and stuff; that way less stuff needs to be ticked but there's the illusion of farther view distance
It seems that the Log4j leak made a top story here in the Netherlands
Wouldn't be surprised. Pretty sure it scored a 9.8/10 in terms of severity.
Uhuh ye, the National Cyber Security Centrum has raised the alarm big time
https://nos.nl/nieuwsuur/artikel/2409121-cyberwaakhond-waarschuwt-voor-gevaarlijk-nieuw-beveiligingslek -> Use google translate if you like
I wonder where this vulnerability was found
It was a MC server
It was found by alibaba iirc
Alibaba Cloud Security Team
Well, it was probably used by black hat hackers much earlier than it was publicly found, to be honest.
Man if someone had knowledge of this before it went public
holy crap that person could've done soo much and I mean sooo much damage
not only to MC
Does the orange on the website mean that 1.18 will be stable soon or no clue?
Updates to Paper do not have any sort of estimate for when they release, ever. Any and all updates will arrive when they are ready, and the only thing to do is wait for them patiently along with everyone else.
Stability is up for you to decide! We just tell you to not to blame us if you deem it's not :p btw take backups thanks
Uh it seems like theres a slight bug with the latest version, you can get achievements multiple times
its happened quite a bit
with the "isnt it iron pick", "Diamonds!", "Monster Hunter" etc
and i suspect more, this is just from the 15 first minutes of gameplay
Make sure to report it then on the issue tracker.
lemme see if i can find it
👍
Hello, I have a quick question doesn't 1.18.1 part two has the same java version as 1.17.1 part one?
1.18 requires java 17
ah I see.
Is it okay to go from 1.18.1 to 1.18 paper?
no, downgrades will not work
There's no reason to do so either
^ 1.18.1 clients can join 1.18 servers and vice versa
Just really need worldedit and my server’s panel auto updated, can’t find a dev build for 1.18.1 yet so was wondering if a downgrade was possible, this server isn’t open yet so it’s ndb, worldedit would just help a lot lol
Worldedit has released builds for 1.18.1
Check their Discord.
Oh sweet, I must have missed that- thank you!
need crash-reports?

This server is running Paper version git-Paper-68 (MC: 1.18.1) (Implementing API version 1.18.1-R0.1-SNAPSHOT) (Git: 1c779c2)
You are running the latest version
Previous version: git-Paper-66 (MC: 1.18)```
Is there a new permission for nether antixray bypass?
paper.antixray.bypass does not work for the nether.
Are you sure that you have the config enabled for the nether in the anti-xray config?
I wrote it in myself
Alright thanks, I forgot to add that.
Under the nether section.
Alright thank you
Yeah I got it wrote in now thanks
Does the experimental version have significant performance improvements? We have a vanilla server with 30 GB or ram allocated to it and when we have more than 6 people on the server console starts complaining about the server being overloaded
certain patches are still missing in experimental, but it's already far more performant than vanilla
You should seee huge improvement
Yes it’s still work in progress
It's likely your CPU not your ram
My CPU was bottlenecking my server and it's a i9-9900k
It's an 8 core something or another. Admittedly not clocked super high but it's peaking at ~40% utilization
Switch to paper and if it doesn't improve anything provide a timings report with /timings report
Sounds good, thanks for the advice
You need to tell us what core model. Potato core?
Minecraft is single core so it doesn't matter how many cores it has, the only thing that matters is single core speeds
It matters in paper as paper has a lot of task done off main thread
not entirely true, minecraft would benefit from additional cores
I will suggest minimum 4 cores on most case
World generation actually will now. Vanilla makes the jump
okay that might help me
Where do you set this?
async threads?
You don’t. Paper will take it if you give it
Unless you are running inside container then you will just set the limit to either unlimited or whatever cores you can spare
Interesting, my timings report keeps showing server oversleep with my CPU utilization at only 30-40
that's because a certain async task is still being waited upon
That would have to do with the CPU in most cases wouldn't it?
it's usually because there are too many async tasks
whats the highest i can make my no tick view distance (now called render distance) without my server dying?
How many players do you have and how good is your server?
no more than 32, obviously
^ I wouldn't do that though but there's really no way to tell the right distance without actually testing it yourself
yeah I'd really say you don't need more than 16
Even if you can handle 16, it'll cause people with crappy bandwidth to lag out upon joining and teleporting
only if they had their render distance up high right? I'm not too sure the internals
Yeah but most ppl are stupid and don't adjust those settings lol
The respect client patch isn’t in 1.18 yet
i thought mojang had it respect client view distance
Other way around
In 1.18 they made the client fog Math.min(client.view-distance, server.view-distance)
Yeah I have a feeling it's the server we're running on. We tried a VPS through OVH on vanilla and it was pretty rough, and now we're getting "The server hasn't responded for 13 seconds" on an actual server
Aikar's Timings Viewer - View Timings v2 reports from Paper and Sponge
I am not aware OVH offers modern CPUs for their vps
horrible garbage collection / memory issues
likely just underperforming hardware
Unsure, we had no problems in the past but this update has just been such a headache
more memory =/= better
dunno how much you're paying for that VPS but you might just be better off shared hosting
e.g. bloomhost or dedicatedmc
Yeah we switched off the VPS because trying to upgrade it was far too pricey, we might look at bloomhost or dedicatedmc. Just trying to play the game with 8 or so friends lol
you know the low bandwith time out change mojang just did in 1.18.1
was that implemented in the paper 1.17 or 1.18 (not 1.18.1) builds?
I believe that was a change Paper has had for some time now, not sure though
hmm
it seems to literally highlight one of the major probs i have been having with the earlier paper 1.18 build
it got a little better with build 391 for 1.17
I dont know if this is a minecraft or paper bug but scoreboards cant detect when you break new 1.17-18 blocks. I tried doing /scoreboard objectives add Deepdiamonds_Mined minecraft.broken:minecraft.deepslate_diamond_ore. But it doesn't detect it.
Try it on vanilla
was about to do that haha
wow, did I just really find my first vanilla minecraft bug!
😱
How am I going to detect how many diamonds you have mined when I cant even detect deepslate variant
you can open an issue on Paper's issue tracker https://github.com/PaperMC/Paper/issues/new -- but for a vanilla bug also see https://bugs.mojang.com
it was a vanilla bug
but will do
bruh I can't log in. Anyone wanna submit the bug instead of me?
Hi, I am getting java.lang.NoClassDefFoundError: net/minecraft/world/level/Level on my server.
I am using paperweight-userdev and io.papermc.paper:dev-bundle:1.18.1-R0.1-SNAPSHOT for development, also i downloaded latest paper jar from the website. After starting server it downloads another jar to ./versions/1.18.1/paper-1.18.1.jar anyway and then after applying patches the jar in ./versions is missing those classes. How do I make it use Mojang mappings? Even when I do copy correct jar from IntelliJ it still applies patches and breaks it.
you need to use the reobf jar
you can use a mojang mapped server but then other plugins depending on the reobf one will break
there's minecraft.mined and minecraft.broken. Did you maybe want mined?
I broke the block in creative and with a diamond pickaxe. Didnt work on either of them on minecraft.broken @hoary wind
Oh but it worked with mined for some reason 🤨
does not breaking in creative count as break a block?
So „default” one that i can download from paper’s website right? It also doesn’t work, how do I reobfuscate my plugin? As I said I use paperweight-userdev and I followed the example plugin (cradle configuration mainly) for paperweight from GitHub
I mean your reobf plugin jar
paperweight-userdev handles creating that
if you copied the example then ./gradlew build will get you the jar
it's the one without -dev or -dev-all
ok it's working, shadowJar is breaking something (jar in build/libs, the one without -dev is working fine)
shadowJar {
minimize()
archiveFileName = "mcbblk-${project.name}-${project.version}.jar"
destinationDirectory = file("$rootDir/build/")
}
build {
delete fileTree("${rootDir}/build") {
include "**/mcbblk-${project.name}-*.jar"
}
dependsOn('reobfJar')
}
Using this jar in "$rootDir/build/" is the mojang mapped one
uh, you don't want the shadowjar
the readme in the example plugin covers this
I wouldn't recommend changing output directories for no reason like that
but you would want to change it for reobfjar, which again is covered in the example plugin
in the build file
well i am using multi-project setup for my development
also you would want that delete in clean, not build
and i just copy jars to the root dir for easy access
it's non-standard
there's no real reason to
unless you're copying it to a test server or something, in which case I'd say something like run-paper is better
symlink go brr
could be better but my test setup consists of multiple interconnected servers with velocity in front
well, create a copy task then
don't modify the output location for the actual build task
you don't need to use build-logic even, can copy that class into the parent build file
clean {
delete fileTree("${rootDir}/build") {
include "**/mcbblk-${project.name}-*.jar"
}
}
shadowJar {
minimize()
}
reobfJar {
outputJar.set(layout.buildDirectory.file("$rootDir/build/mcbblk-${project.name}-${project.version}.jar"))
}
build {
dependsOn('reobfJar')
}
That's working for me now, although you are right i maybe should do it differently
ESSX discord doesn't do as good of a job

how is this related to essx discord
you were here
you can ignore that, it's a harmless warning
I guess I somehow thought those messages were related
Wait the warning message changed, does this mean it’s stable?
What does the message say?
Yeah I know but I meant can we use it for servers now
Since the “can’t be used for production” is removed
Okay I'm a noob to crash logs, are they just in the log directory or somewhere else
Is there a list of any known bugs in the jar
(It was changed to be less “aggressive”, but just make more confusion ig)
The issue tracker?
Wait nothing changed? I thought it was like red > yellow > green because someone in my server told me a build is out lol
Oh well rip
The text makes it clear. As it says, use with caution, backups recommended, and that these are early builds.
is 1.18 stable yet
They shortened it though, it also had “don’t use in production environments” so I thought it became somewhat stable atleast
welp, it literally says experimental in the title. off to the dunce corner with me

might be dynmap
--- DO NOT REPORT THIS TO PAPER - THIS IS NOT A BUG OR A CRASH - git-Paper-68 (MC: 1.18.1) --- 😉
well the server did crash
Yea that’s dynmap
Does paper disable bedrock breaking?
yes bananaman, however there is a config
you should be using squaremap
And in the future, please use a paste service.
How do I reenable it
Having problems with TNT Duping, Bedrock Breaking or Sand Duping Vanilla Exploits? See: https://github.com/PaperMC/Paper/issues/3854 for information.
does squaremap have 3d renders?
see ^
no
ehh i can disable dynmap for a while to see if that fixes it
then update dynmap later
last update I pushed will actually improve dynmap performance a bit
spigot was round tripping things with codecs instead of just copying 
Thanks codecs 😻
esp the first few weeks its good to update a lot
If I have set the view distance to, lets say, 24 chunks, in my server but the client have the render distance to 12, does all the 24x24 chunks sent or just the 12x12?
Only 12x12
on 1.17, only the 12x12
on 1.18 that hasn't been added yet. And for vanilla/spigot/etc, the 24x24
Oh, is not implemented yet? oh
Huh the server just ignores client side render distance..? 🤔
vanilla server yes
always been that way but paper make it respect client distance. The patch just isnt there yet. coz leaf is busy changing his name 
Huh that’s interesting…. x)
So if I set the view distance to 24x24 it will take longer to load, right? I see, thank you
Make sense
Is it possible to have view distance per player or something like that? I remember being a thing in paper
no that was a plugin.
Oh, thank you!
how do I fix people getting stuck on lecterns
There’s currently an open issue for that, a workaround isn’t known currently.
wait was that not a vanilla feature
no
Does the client then just fog out the outer chunks? 🤔
their contents are probably loaded in RAM but not sent to the gpu
I know that just past the fog it doesn't actually render anything
yeah I'm not certain if the chunks are stored or not but the packets do have to be processed
which combined with the lack of rate limit can cause issues especially for slow or bad connection clients
People who complains that the chunk doesnt load when they switch worlds or teleports is usually because of this 
build #69.. heh nice
has anyone had any issues with paper 1.18.1
how "risky" is running on the unstable builds? Would it be worth the time to just run on spigot until a stable version is released?
unstable means running it on a server that you have a playerbase using is not recommended
you can do it if you'd like, but if you do, you'd be dumb to not take backups
you can look up the current issue trackers for the issues people can recreate but you are going to make regular backups
im not doing that tho
there aren't any known serious issues
main thing you'll run into is https://github.com/PaperMC/Paper/issues/7043
Expected behavior Should be able to walk over or on a lectern. Observed/Actual behavior See video: https://m.sjh.at/2021-12-06_18-07-00.mp4 Cannot walk across as the player is constantly teleported...
There are also some fun cave vine crashes
if you're using an unsupported old version of java lol
yeah if you are getting that on java 17 (non-ea), you'd have to elaborate, I'm not aware we have any valid issue for such a thing
secure using paper 1.18.1?
see above, there aren't any super serious known issues
or if you mean secure from this new exploit, yes
yes you can find them on google. Most big one are already updated.
can you link me one? i only see old ones like 2020
i cant seem to find a good just world teleport mod
like even a sign one
then you do it
why?
Multiverse Portals should still work fine, even if it was updated some time ago
Is there a multiverse for 1.18?
the 1.17 build most likely will work, MV tends to be pretty stable over updates
Does no-tick work in 1.18 yet?
(no, but view-distance is basically no-tick in 1.18)
short answer: vanilla's implementation works, paper has not updated their implementation
are they planning to?
chunks are taking time to become visible when loaded
atleast for me when i update my world from 1.17.1 to 1.18.1
this may be due to the cave generation under existing chunks
yes. i believe Leaf is maintaining those patches and is busy at the moment
Yeah, I'm finding that chunks hang
ye but do 1.17.1 chunks have to have solid deepslate below them
ye it happens when i first load in to a comverted world but chunks load after time
Upgrading chunk takes time. It will likely be improved later
not sure what your question is? if the chunk has bedrock at y0 it will generate caves below y0 and y-64
hey is there a bug that makes it where i cant interact with inventory in my server or is that just me?
doesnt appear to happen on my vanilla server
Haven't seen anyone else report that bug in 1.18 yet.
Does it happen often? If so, how?
*my friend's vanilla
So check your plugins?
i try to move an item in my inventory and it rubber bands back into the inventory slot it was in
how often does it happen
every time
that seems like an issue with plugins. Even after a server restart?
if it happens every time it’s probably plugins
Try removing plugins and try again.
hmmm
disabling plugins didnt work
im still rubberbanding my inventory, it must be a server thing
is there a spawn protection thing that i just need to turn off or?
That shouldn't matter. Are you in a weird gamemode or something?
Or any weird client mods?
im just playing survival
im on sodium but nothing happens on my friends vanilla world
Pretty odd. Haven't seen a single person with that problem.
Rubberbanding inventory could happen if you have a super bad connection to the server.
I'd try with a bone stock vanilla client and see if it still happens.
sure
@regal fable is anything else rubberbanding / lagging?
Failing that, try saving the world and configs and starting a new fresh server with no settings.
im using 1.18.1 experimental
Right
vanilla works just fine btw
i just changed server type and that problem doesnt exist, so it must be spigot or some setting that isnt turned off
Hi guys, so far was using the experimental version to check out the features and all (without doing much for optimizing the server), main being the world pre-generation thing as it can take long hours. As I see the early version is out, is it recommended to reset and start the pre-gen process or should I wait for some days more?
You shouldn't need to restart pre-gen.
Sorry, not sure what this means. It's working fine now?
yes when its on vanilla
I didn't pre-gen my server before.. I will start it if the current version starts to be stable enough.
Vanilla client?
no vanilla server
Try with a vanilla client - no mods - on your server.
Well this is Paper, so I'd hope you're using 1.18 Paper.
And not spigot.
im using paper spigot
Minor correction: Paper is Paper, not Paper Spigot.
ok then ill try paper instead of spigot
Where did you download the server jar?
im using shockbyte server manager
Ah
but yeah idk how a client side mod would change inventory interaction on a paper server and not a vanilla server
packet limiting
Mostly it's about changing stuff around to see if anything ends up different.
But Paper and Vanilla don't always behave the same.
it can 100% do it and that's why testing on vanilla client is important.
Always good to try to eliminate variables.
ok same thing is happening on spigot so we know its not paper specific
ill change it back to paper and play vanilla
@timber ridge happens on vanilla too, it has to be something with the server
Alright, so the next thing I'd try is a fresh server instance with no config changes.
Honestly I've never seen this, so I have no idea.
i didnt change any configs?
There have been zero reports of this from anyone on any version.
ok well
Can you do /ver and show which build you're on?
send it to the bug list i guess
have you change anything at all?
spawn up a fresh server right now and see
with vanilla client
this fixes it for sure i already checked
to open an issue, you will need steps to recreate
Okay, most recent 1.18.1
if that fixes it, it isnt really a bug it's something to do with ugh...
i also noticed item drops are invisible
ugh?
yeah if it doesnt happen on vanilla client it's probably just your mods
they're all disabled
it happens on vanilla client not vanilla server
fine ill remove it
I am now 100% confused
Me too.
i am still gecko
if vanilla fixes, but modded (with mods disabled) doesn't, I'd say it's something to do with modded.
ohp just found it i think
"it was my inventory tweaks"
i installed mods directly into the file manager instead of the server manager so i think it didnt appear in the active plugins list
what
yup
I hope you are using a sane mod manager like multiMC...
so basically there a server-based file managers like FileZilla that lets you interact with your server folder directly, and then there are server managers like MultiMC through Shockbyte
Ah gotcha
installing a plugin through filezilla doesnt show your installed plugins list in your multimc
Well glad we could kinda help I guess :)
since when are we talking about plugins
just note that if anyone else says this happened tell them to delete their old plugins
scroll up
this is always the golden rule 
thanks i dont know why plugins would be problematic if disabled
@dark wigeon hi
omnipresent
Its working perfectly
Disabled plugins still load and can do things, they just don't get to listen to events, commands, etc
So if the "plugin" is actually a mod that on load modifies server internals....
It might actually be more broken than if you just let it run normally, thinking about it
Hi! I run my server with difficulty "easy" by accident. I set it to normal in server properties and restart but the server is still easy! Why?
You can try running /difficulty and seeing what it returns.
/difficulty 1 will set it to normal.
But on restart it should pull from the server.properties.
Isn’t that only on world creation?
dont think so
I don't think so
Might be something else then
isn't that, like, pre-flattening? /difficulty normal should be sufficient
Wiki says numbers are BE only
IIRC /difficulty should output options
Yeah looks like numbers don't work - the chat warns you.
So it'd be /difficulty normal
And doing just /difficulty does tell you the current difficulty.
Thanks. I will try
is paper stable yet?
theres a reason why this channel exists :P
damn
but at this point no major issue other than the log4j exploit has been reported so far
many people are already running it and it seems fine, just take backups
we just wanna have a survival playthrough but obviously avoiding world corruption is a must
me and a few mates
we might just wait a few more days
hopefully it stabilises by then
Should be good enough for that @vale vale, just keep automatic backups
When updating an existing world from paper 1.17.1 to paper 1.18.1 do I need to do something special or will it do that for me automatically? Just want to make sure my worlds don't get messed up
Never mind, --forceUpgrade just decided to start working - is that really necessary tho for larger worlds?
What backup are you guys using? Plugin or your host's built in?
I just do tar -cvzf backup.tar.gz minecraft/ on my VPS
If you do your backups on the same disk your server runs on, you can also use these backup plugins lol
I'm sure there are quite a few methods of doing it, I haven't run a Minecraft server in years so I didn't know these existed
The tools I mentioned aren't tied to mc only, you can use them for sure in other environments too
Thanks, I'll check them out :)
we discourage usage of that, it should never be needed
So the server will handle upgrading the world on the fly by itself?
Yes
Alright, much appreciated 👍

TIL papermc is a nodejs app
mojang must've moved from Java to JavaScript because they have similar names!! 😳
Even if that was the right project or language that's not even a bug, that's a network issue
ok, I thought it may helped
Make a github issue so mojang fixes their discord bot
i think you can make a minecraft server running in node js
i saw it somewhere

Has anyone else been experiencing an overload of ram since updating to 1.18?
1 player online and 6.5GB of ram being used
not really but there was memory leak on first experimental paper build
i updated to latest version and it was fine as on 1.17.1
yeh, I'm on the new 1.18.1 and I'm still getting a stupid amount of ram being used. 1 player online with 6.5gb ram used it very overkill, no idea what is causing it
You can do anything in node
it has fuck all to do with us
We're seemingly found the issue and a workaround for the leak
turned out to be exactly what some of us where expecting :L
must be one of the plugins i guess
With 1.18.1 I've seen Lower ram usage (pterodactyl)
I use pretouch, but algo a plugin that shows me the "real" ram usage.
The overload May have to do with chunk generation.
Does upgrading worlds mean something other than switching from 1.17 to 1.18? Because the server i've been running has been using all of its ram as well, but we've only ever had it on 1.18.
'using all of it's ram" means nothing
unless you're running out of ram, it means nothing
This is java.
fuuuck me is chunk loading slow as shit on spigot...
Heh, Spigot
Has chunk generation improved on Paper since the initial 1.18 builds? I remember in Leaf's updating stream he showed the difference between 1.17 and 1.18, and it was a pretty large difference.
a few days back I talked about timeouts in 1.18 paper, and apparently we found out that allowing players who struggle with connection to bypass anti xray will somewhat improve their situation: if they even see the void, they'll spend so much less time in it, but they still can get timed out sometimes. might assume that's because chunks are much larger in 1.18 by size and anti xray (mod 2) increases the size even more. maybe this will be helpful to anyone; you can enable bypass via permission in paper.yml and then give that permission to individuals struggling that you trust (trust, because that's defeats the purpose of having it in the first place). I completely forgot we had anti xray on paper lol, should've tested it first
anti xray adds some overheads
the fact that chunks load kinda fast causes connections to flood, especially given that the rate limit patch isn't in 1.18 yet
it looks interesting from the perspective of player, like they get ‘teleported’ to coordinates like (8,8) and the fall, if they look up they can see these chunks become visible from one side to another, but then they get ‘teleported’ to their actual location, start falling again, same from one side to another chunk appearance and then after chunks fill up they teleported to their previous Y level with bones crack sound
this 8,8 is really interesting, I won't deny that maybe there's a plugin involved, but we don't have any stuff that has any deal with tp besides essentials, need to check it
I mean, you'll join the world
you'll be falling because mojang made the client exit the prep screen before the min chunks are there
but, there shouldn't be any teleports
Like, outside of the teleporting back towards the surface cos often it has the chunk at some point but just refuses to render it
does client immediately know its location in the world even before chunks are loaded? actually, no, that still wouldn't explain the chunk loading.. I really gotta check all plugins (gladly there aren't that many)
You may have been affected dude 🤯
by the log4j thing
who knows
Literally nothing to do with that
Someone ran Doom with that thing
at least, nothing they've said indicates jack shit towards that; they provided 0 info, 0 context, speculating into "your systems been hacked" is just dangerous and stupid
node.js x)
I get it, "java ram usage as a reference point is absurd."
Hey guys - I'm trying to build the latest master of the Paper repo, but compilation fails with:
/home/tux/Projects/Paper/Paper-Server/src/main/java/org/bukkit/craftbukkit/entity/CraftLlama.java:49: error: setStrength(int) has private access in Llama
this.getHandle().setStrength(strength);
I guess I'll just have to wait for a fix?
Or just fix it by urself
I'll try and report back
Does anyone know if there are still world generation features missing in paper 1.18.1
Trying to figure out whether I should use the latest build to generate my new 1.18 world or if I should wait a bit
literally nothing is missing or has ever been missing from world gen
only thing missing are patches which improve the performance of the server
Ok ty
That's why I love Node.js
want to ssh into a server using node.js or whatever? sure. Want to control your fail2ban instance on your machine? YOU CAN DO THAT!
did rightNow 1.18.1 Stable?
Typo, you can't do anything in node lol
I mean probably but 200x harder than other Lang's
And we always recommend taking backups, that won't change
Because it's still an early build?
It's hot off the presses, eat pizza fresh out of the oven with caution
Latest master should build just fine. What steps did you take?
clone repo, run apply patches, then create a jar
Anyone else experiencing crashes with 1.18.1?
Can you provide those crash logs? 🙂
Thats the issue, it tells me nothing:
..../entrypoint.sh: line 14: 11 Killed java -Xms128M -Xmx4096M -jar paper-1.18.1-71.jar
Idk if its a host issue or what.
so, it was killed by the host
Alright, contacting them.
check syslog, whenever i get that it's a visit from the oom reaper
oom reaper? Care to explain I'm too unexperienced with this.
Is there a way to not extend a world to y -64 when updating a world from 1.17 to 1.18?
Nope, 1.18 goes tgat low in vanilla now
if your systems runs out of memory it will start killing processes it considers unimportant
-.-
I found (by accident) "a way": Change level.dat to a flatworld with "void" settings, update world and the world only generate air 0 to -64...
now I "only" need a way to go back to Y = 0 ...
or, rather, if an application requests more memory than the system has
can i drop bugs in this chat, because i found one
forceUpgrade iirc will bork the retrogen but you'd need to test that
there's a spigot.yml setting for disabling the retrogen stuff. new chunks will have the -64 height tho
but, changing dim height is basically unsupported
So, er, am not sure what I'd even suggest there
Depends on the severity
world-settings.default.below-zero-generation-in-existing-chunks thanks, I will play a bit with that setting
the lecturn glitches when you place it down
you can still build to -64 in existing chunks, and new chunks will generate down to -64, but old chunks wont generate stuff below 0
@fluid badge https://github.com/PaperMC/Paper/issues/7043 ?
ty
By mojang or by spigot/paper?
ok, than I fill that 64 blocks with bedrock -.-
thanks for help..
stop mentioning.
I did clone it again and it worked fine 👍
Not sure what happened there
Is there a way to make two different paper instances utilize different CPU Cores
Ill be running two servers simultaneously and want to split the load
that's on the OS to deal with
are you using all your memory? if your server has 4GB, use -Xmx of 3G, Java needs memory on top of heap to operate
Do I need to update my config files like the paper.yml when I updated from 1.16.5-1.17.1-1.18.1?
i believe paper handles that for you
It automatically adds new settings ^
new values will be added, sometimes we migrate settings, etc
"why my 1.18 server lagging"
also why render distance low? to improve performance?
if you mean the fog,mojang has fixed that
that's the client
yeah i am
ill try that
don't mention.
ok
If you updated the server from 1.17 and you used no-tick view distance it no longer works. You should increase the view distance in vanilla config file and set simulation value to what you had in papers config for no-tick distance
server.properties?
ye
ok
it was at 3 before
will it be better to just delete all the ymls
why is the render distance for the end and nether so small
like so much fog
Hey Im trying to use the paperweight userdev plugin but I always get this error:
SpigotLibrary:test: Could not resolve io.papermc.paper:paper-api:1.18-R0.1-SNAPSHOT.
Required by:
project : > io.papermc.paper:paper-server:userdev-1.18-R0.1-SNAPSHOT
do you have the paper repo added? 🤷♂️
I have an paper repo under pluginManagement do I need another one ?
that's just for plugins
but in paperweight-test-plugin does not contains any repository
thanks now it works
can anyone answer?
check your config?
you've likely set it that way, you can configure per-world view distance in spigot.yml
but, really, it sounds like you aren't super familiar with the config and it's all messed up for you. I'd recommend deleting all of them so they regenerate back to the defaults
well I mean you can set whatever values you'd like-- I'm not telling you you have to delete them. It's just that you don't really seem to know what you have/haven't changed. Ensure you have read the docs and understand what you're changing before you change it
ok thanks, i deleted my ymls and it helped :D
Anyone with "not loading chunks" Issue?
What’s your view distance?
Currently the server will send all chunks without speed limit nor care what the client setting is and it will overload client that has slow internet
View distance: 9, I use Orebfuscator if that could be the issue?
Only for some players. While one can explore for others chunks simply stop. Until relog, solves the issue, temporarily.
Paper does not prevent ESP.
It will be even more likely if it’s only for some players
Go back to my original point about network
I use a hosting service. Best hardware avaliable. I doubt they have a bad internet for the bold price I pay.
not the server's network, client network
^ I was always talking about client
All players have 5 bars. If else, I am not aware of it.
individual players may have internet or computers that isn't epic and will be overloaded by several hundred chunks being sent at once
bars are latency only, not bandwidth
Found a pretty big deal 1.18 issue, from what I can tell. I'm using a datapack to add some custom worldgen features, most of which works fine, except for custom biomes in the nether, which are not generating at all as of 1.18.
This is strange, specifically because custom biomes are generating in the overworld, and the world generation features in existing nether biomes are generating perfectly fine. Transplanting other region files with said custom biomes is also working, so it Is just a matter of these biomes not generating. Even the double world height of 256 blocks is in fact working fine, just custom biomes not generating, & I've been poking around & haven't seen this reported anywhere.
Ping is not a good indicator of network status. It’s just a snapshot
Please test without the plugin and lower view distance
Not quite sure. It happens since the 1.18 update, for players, including me, that never had issues.
^ it's only a 1.18 issue
everyone in my server freeze in the new update
Please provide more information
Hey can somebody tell me whats the equivalent to PacketPlayInUseEntity in 1.18 ?
if im just Missing something n someone could let me know i'd appreciate it, otherwise if someone could report this in whatever proper channels to report it in, or lmk where to do so i got a little confused abt that admittedly 🤷♀️
did the datapack work in 1.17?
Yes. I did update it to work for 1.18, and tested to see if it would in a singleplayer world (it did), & i know its not a like, datapack issue Because ive been through it pretty thoroughly & again all the custom generation Features are working, the biomes work when transplanted, & custom biomes in the Overworld are generating on the server. Super weird thing tbh.
(giving all this info bc the 1.18 worldgen stuff changed pretty dramatically, so porting worldgen datapacks from 1.17 to 1.18 isn't exactly possible 1:1 in the first place, but the datapack does in fact work & the predecessor version did work as well)
Ok so i get this error where i get kicked for trying to sleep in a bed what do i do
depends on the error, care to share it?
Wow my discord did lag out to old messages
Did you actually install the datapack in the nether world? They're separate things in Paper
Otherwise file an issue on https://github.com/PaperMC/Paper/issues and provide the datapack along with what you're seeing and expecting
Hi, not sure if it's the right place to ask for help, sorry if not. When I open the latest 1.18 jar the window pops up for a moment than closes automatically. Do you guys know a fix for this?
oh, yeah, that must be the issue, didn't know it required 17, I have 16 dev kit. Thanks 😄
datapacks aren't per-world
even though the folder is in the level-name world
what's a bug?
datapacks being per world?
is the client even sent those packets relating to datapack stuff when they change dimension? like updating tags, recipes, advancements..
If not that's a bug too 😛
Unless it's not possible for the server to send those other than on join
I don't think its not possible, but its just not done afaik
CB multiworld is supposed to have the worlds be isolated
The only concession to that is having vanilla portal mechanics still work
well datapacks weren't a thing when that change was made yeah?
Don't Datapacks do most of their work on scoreboards ? Seems horrible to implement that on a per world basis
what? what's the relation between datapacks and scoreboards
Their functions
I think they mean with functions and stuff
oh you mean the functions people make
I mean the generator settings sure
yeah, there would be TONS of datapack incompatibility if they were per-world I think
It would be annoying to miss out on that stuff but that's why you'd just install that datapack on every world
But going to a new world should be like going to a new server
well, that's what you use a proxy for
In that case you may as well drop the multiworld changes entirely
Aren't scoreboards from the CB time tho ?
Why aren't those world unique too then
Because that rn seems like the worst issue one would have to solve for datapacks on a world basis
hey, is anyone else having a problem with anti-xray not working?
What exactly isn't working ?
Another question, any idea how to fix this? I get this error message when I try to connect to my server.
reproduce without plugins™
I did, though the individual nether generation features were working with it just being in the normal world, too.
Yeah as someone else seemingly explained already whoops
(Like even in 1.17 having a nether generation datapack in world as opposed to the nether folder is what works, but I did check just to be sure, too)
And, again: the worldgen datapack changes DO happen in the nether, like. For instance I have some unique plants using the pack, & they generate Fine in the preset nether biomes, its Just the custom biomes that aren't generating and Only in the nether, not in the overworld (where custom biomes generate fine)
(And those changes in the nether are present with the datapack being in Just the world folder)
Anyways I won't be at my pc for like another day if someone else wants to test & set up the official report, otherwise ill do it when im home lmao
Scoreboards are iffy. We also don't do per-world inventories which is a more obvious one. The problem is datapacks do a lot and some of that we'd definitely want to be per-world, like worldgen
Recipes should probably be global, advancements maybe not? Although vanilla advancements require you to cross worlds so... maybe
It should be possible to make terralith only apply to a single world though
Can you do that in Paper?
If not multiworld is pointless and should just be removed
Agreed already tbh, the only thing I've found useful for it is being able to set unique gamerules, like no nat regeneration in the end, shit like that that should Really be delegated to Plugins anyways
But the worldgen thing im talking abt is def just smthn that broke in papers 1.18 builds, ill detail it again from the top in a report when im home if someone doesn't beat me 2 it
So I tried updating to 1.18.1 latest build as of last night and I did some world trimming and generating for smoother stuff and my server stopped responding part way through.
more details please.
what build number is "latest"? (hint: it's in the filename) was there anything in the console? what's your plugin list? what were you doing at the time?
I mean, if you mean, I fired up a mc server and started running around a world created in an earlier version
we have created a bug report with mojang due to a memory leak
i was in fact able to create a bug report, here's the link https://github.com/PaperMC/Paper/issues/7103 for any of y'all earlier who were confused on anything or wanted a more concise summary.
How is 1.18 is doing? I still haven’t gotten around to setting my testing server but members are still pestering me.
I believe 1.18(.1) is considered stable by Paper but not forgetting to update every once in a while will keep you good
I've had a couple of memory leaks on a tiny server, although I haven't bothered to find the cause. It runs fine otherwise.
likely related to this
Most likely
if you're loading an old world
yeah, source was found, been reported to mojang
we have a fix but I'm not sure if it's the best, waiting to see if they say anything
New world isn’t affected
Might I ask what makes the world considered "old"? Because this one was created on the 10th.
generated with a version older than 1.18
Hmm, that's odd then. It was created on 1.18
well, there have been a few other leaks reported to mojang/us but they seem to be much more edge cases than the one with upgrading chunks
I'm sure it's already been reported, I know it has something to do with the loading of chunks as it only happens when people start exploring around.
If you can find a method to reliable trigger the leak, do make a report!!
I would if I had more info, I'm not really the best when it comes to debugging minecraft stuff. Don't want to step on any toes.
You don’t need to know the root cause when reporting. Just steps to trigger it
git-Paper-71 (MC: 1.18.1)

And a heap dump if possible. That’s it
Even the method to cause the error with no other data might help, if it's a method that would work to help someone else pull data from the error.
Are you pregenerating chunks???
Those chunks should already exist, but I am just running it again over them in the hope it updates them with the new 1.18.1 bits.
The first time I tried updating, about 90% of the animals around me when I logged in fell out of the world.
I used chunky the first time and it still happened.
Third, pregen with no plugins but chunky
Nobody but myself is able to get on the server and I wasn't online when it chose to freeze.
theres a known leak thats already reported here about that sorta thing https://github.com/PaperMC/Paper/issues/7094
itll still happen without pregen but not as bad, but it only happens once per chunk so if you restart your server a few times itll prob get better
just make sure to stop it before it crashes 
yeah lmao
one thing vanilla server gui is useful for
no
it crashes after 2-5 minutes
im pretty sure most of the instances of people saying their server randomly crashing from OOM is from that tbh

How long will this take
I can test it
literally enabled gui just for that issue lol
with pregen i had my server crash with 4gb memory in 1.5 minutes
makes you wonder how much world upgrading is tested
without, just flying, like 6-8 min
you said it not me
the pr jmp made definitely seems to have fixed it though
I guess I managed to dodge this coz I restart each day to make backups
Never had OOM myself
And I didn’t pregen
the issue only happens in 1 minute if you run chunks over an old world
chunky*
otherwise it'll happen much slower
I see I see.
but will still happen
My very wise choice of using a new map without pregenjng is paying off
i mean tbh you really shouldnt need to --forceUpgrade or reload existing chunks anyway cause data fixer in paper is so fast
but afaik most people encountering the issue from pregen are intending to expand their worlds
they just run into the stuff on accident
wait is there a difference or am i just thinking of the mojang name
i thought it was "data fixer upper"
ah ok
"rewrite", more like replacement system I guess
lol
Now i understand why leaf still hasn't wake up.
im still having issues with this... really strange. i have 3 projects that are set up to use the 1.18 userdev, 2 of which work fine, but this one project is still giving issues. ive nuked caches & invalided caches on intellij (not sure if thats any different) but its still not working. java 17 is selected for my SDK on the project in intellij, my toolchain is j17, and compileJava is set to use j17.
What issues is it giving you?
i cannot compile
with what reason?
paper 1.18 userdev
give us errors, screenshots, idk something to help us help you
i included an error in the message
nvm I didn't see the reply lol
retiredleaf
So it’s almost stable, how’s the memory leaks with 1.17.1 worlds going?
My plan is regen some unused chucks in the spawn region before trimming the world size and porting it over to 1.18 for the new world generation.
Not sure how I’m gonna do that atm but it’s my plan at the very least
just watch this issue for when it gets closed https://github.com/PaperMC/Paper/issues/7094
Will there be any issues with stuff built above bedrock in 1.18?
shouldn't be, no. the bedrock will just be replaced with deepslate
unless you forceUpgrade, in which case it will not. But don't do that
what about in the nether?
My nether did upgrade perfect with all kind of builds on the roof
Some old portals did make a new one when going to overworld and that hasn't been loaded in 1.18 yet but eh that's minor
Ok. Some people have some very complex (and laggy) farms up there. Kind of wish I didn’t let them up there but very well 
Backups is key ofcourse
And backup the backup and so on lol
Haven't tested that but would think same as 1.17
As i used chunk loading for that in 1.17 and worked
I mean the “stock chuck loader” I have no clue how that thing works but I’m worried about lag around them
Is it always loaded?
lol
i dont understand how that is
i have 20 online on latest 1.18.1 paper
no issues here lol
ah cuz i have fresh 1.18.1 world

whats the best way to perp my world for 1.18? what tools should i use to trim the worldsize and regenerate chunks?
MCA selector
Chunky can trim chunks too
Specify a size and shape and instead of generating you can tell it to trim everything outside of that
Oh does it do chunk inhabited time too?
No?
I suggested MCA specially for that so you can trim away the chunks no one “lives” in
I guess I've never thought to even try something like that, always just wanted to trim off the crazy long exploration lines people went on
That one person walks 100k to make a dirt house
Then again before 1.18 it wouldn't even attempt to blend so you wanted as few borders as possible to manually fix
thats my plan, to do it by hand so no houses get trimmed
You can look into the program I suggested then
As always make a backup and test the backup first
i think while im there im gonna pregen a radius of spawn so i have a crust of 1.17 world gen before 1.18 world gen
i plan to backup before and after i do the save editing
Stash does get trimmed though
stash?
If a player purposely move to a remote area to store their good and immediately leave
If you go by the inhibit time, it will not present. But that’s on player 
i will have a copy of the world open so i can check chucks of interest so stuff like that are not nuked
it would be cool to do this at some point lol
I will be waiting 
too late for 1.18
MCA selector is nice but you gotta get a beefy PC it’s like opening a big project on photoshop kinda load if your map is big 
You can do it for The Wild™️ update!!
is that what the next one is called lol
Yeah
my world shouldnt be too big so far
And you have to download the world to your PC, open it in MCA selector, then upload it back to your server
See you next month
you can do it through sshfs
im currently downloading my 1.17 world and its like 80gb lol
1.18 seems stable enough (aside from the upgrade problem)
That's the same thing just doing it on demand (and multiple times)
make sure to... turn off your server, before screwing with mcaselector through sshfs
they've also got a fancy cli, so something like java -jar mcaselector.jar --headless --mode delete --world ./world/region --query "InhabitedTime < 5 minutes" will also work
ooh
EZ
TIL about headless mcaselector
I looked for that but concluded it doesn't exist because it's not really documented
The dev been hard at work. I really like it
dont worry, i will be screwing with a backup
cli? whats that?
mcaselector is honestly such a good tool though
if you're just using a shared host, using chunky will be the easier and better solution
unless you want to download everything to your pc and use the mcaselector gui
i have the box here in my livingroom
can chunky delete a list of chunks? :o
i think i will be using chunky anyways as i want a radius around spawn of 1.17 world gen. 1.17 world gen is a little more friendly
gonna set it up as such so wont have to go far but it wont be hills and shit all around
we're doing this crazy scheme where we do manual resets upon request, owners of towns get to choose the shape of where new chunks generate
im thinking of doing that cause this seed has been well. unkind
1.18 terrain is honestly super hilly
too hilly for me. i have yet to see anything generated in 1.18 thats flat
I like that 1.18 kinda provides a balance
there are areas of 1.18 terrain that look like they could have come out of 1.7->1.17
old terrain gen was nothing but flat
Now we're back to beta 1.7 style but with the biomes and such like newer versions
And the increased height and the new caves and etc
mojang's advice is "if you don't like the terrain you see, go somewhere a few thousand blocks away" and I kinda agree
although... that advice is what they gave the community when they surprised us with beta 1.8 huge oceans all the way back in 2011
but I like huge oceans so
we have a huge desert to the north, MASSIVE sprose forest to the South and a rather big body of water on the east and west.
I've found what definitely seems to be a bug but it persists in pure vanilla. Furnaces eat up your fuel credit when they aren't smelting anything. Put in a piece of coal and a cobblestone, and once the cobblestone is smelted the flames in the interface that indicate fuel level credit go down to nothing. So lava is worthless as fuel unless you use it all at once.
This isn't a paper bug, but paper patches this sort of thing, right? Where should I report it?
so like 3(4 if you count the ocean) bioms before going 1000 blocks out
This is MC behavior since literally when furnaces were added to the game?
hmm, maybe I'm crazy then. Swear I didn't notice it before
wait what?
do you mean it runs out or just goes away?
it has always used up the flame whether or not something is smelting
Yeah I'm crazy, never noticed that. But never used lava much as a fuel source before. Thought I remembered being able to put a bucket of lava in to smelt a couple things and then use up the rest later. Guess not
Only actual bug I've noticed then is the bugged out lectern hitbox bug that is already reported and confirmed
I don't remember it cancelling the furnace flame
the flame keeps going until the timeout
you can put a bucket of lava in a furnace and it will last for a number of ticks
hey, is 1.18.1 paper still experimental
i think it still is
the only main issue remaining is upgrading old worlds will cause the server to run out of memory
oh thats it?
server: "I forgor 💀"
Pretty much all of the tuinity patches haven't been updated yet either, right?
but that's a vanilla issue as well, only main paper issue you'll run into is https://github.com/PaperMC/Paper/issues/7043
Expected behavior Should be able to walk over or on a lectern. Observed/Actual behavior See video: https://m.sjh.at/2021-12-06_18-07-00.mp4 Cannot walk across as the player is constantly teleported...
Im resetting my world so wont be an issue for me
leak, or just super high usage?
leak, it causes a crash
both?
It's a cache that holds on to the region and seems to never get invalidated so...
I mean a leak will eventually be super high usage 
You use paper yes
yes
most have, a couple big ones haven't
did tuinity merge into paper
ye
yes
oh I see
tick view distance not updated 😦 i loved that thing
