@torn robin Nothing relevant, other stuff but i can show you

harsh anvil
tbh as long as you just add and remove players it doesnt really matter
worn temple
Yes, but objects like that shouldn't be used as a key in the first place. so use something better that is tied to the data.
spring drift
I just changed a plugins source code, how would I compline that into the plugin itself on the server.
tardy lance
brisk mango
Okay what should i use instead of inventory?
if i need to store inventory objects
Well and another thing, ive still havent heard a proper reason why they shouldnt be used as a key
tardy lance
@torn robin in survival it doesnt duplicate
torn robin
yeah so it's a creative mode thing
tardy lance
yes it is away
worn temple
Inventory has a value comparison, multiple inventories can have the same value. So therefore a collision is possible.
tardy lance
if i remove line 33
worn temple
UUIDs cannot have the same value for example, no collision is possible.
tardy lance
but can i prevent that it doesnt work in creative? @torn robin
worn temple
(technically yes, but they are unique enough that the mathematical chance it will happen is longer than the universe will exist, so good enough!)
brisk mango
Inventory has a value comparison? what
how can multiple inventories have same value
when you create a new inventory you create a new instance of inventory
minor laurel
hi
brisk mango
how can there a collision happen
torn robin
@tardy lance what are you trying to do exactly?
spring drift
I just changed a plugins source code, how would I compline that into the plugin itself on the server?
harsh anvil
contains/get uses equals internally and from what i can see thats not being overridden by inventory so it uses the hash to compare
torn robin
also hi Alice
tardy lance
I want to lock this item in inventory
harsh anvil
which is the same as uuid's
tardy lance
that you cant move it
torn robin
@spring drift have you tried exporting like regularly
worn temple
that's instance comparison, not value comparison. New instances can have the same values.
Long a = Long.parseLong("123");
Long b = Long.parseLong("123");
Both a and b are different instances, but they have the same value.
torn robin
Verilyzed you could try setting the result to DENY
worn temple
typos, who cares. ¯_(ツ)_/¯
tardy lance
What result?
torn robin
event.setResult
spring drift
I don't know anything of compiling. What does exporting mean @torn robin
torn robin
uhhh
harsh anvil
You're wrong in this case tho, only the objects hashes get compared, nothing about the contents of the inventory
naive goblet
Google "export" pig
torn robin
how did you change the source code
tardy lance
event.setResult(null); ?
torn robin
Result.DENY
spring drift
I mean like how would I export
harsh anvil
@spring drift usually people use maven or gradle to build their jars, but you can let intellij build the artifact too
or eclipse whatever you use
brisk mango
@worn temple no shit they are different instances but same values. Thats what we are fucking talking about all the time, if inventories have different instances, how would they collide then when you would use == to compare them
and you keep saying bullshit about "complex objects" that doesnt make no sense
worn temple
because when inserting or getting something by key in Map is a value comparison, not instance comparison.
torn robin
right click on the project and click export assuming you'r eusing elcipse
brisk mango
getting something by a key isnt a value comparison
brisk mango
exactly
harsh anvil
which its not in this case
tardy lance
@torn robin Same issue
torn robin
well no idea then
brisk mango
just stop talking @worn temple please
harsh anvil
no need to be so rude, but yeah you're not correct
brisk mango
i dont wanna be rude but this guy is acting like he just studied 50 books of java but totally doesnt know shit
and everything he says makes no sense
harsh anvil
Yeah welcome to spigot
tardy lance
hm
worn temple
I've been working with Java for nearly a decade now. You're just an idiot. Its standard convention not to use mutables as map keys
You seriously suffer from the Dunning Kruger effect
harsh anvil
you say that yet what you're saying is wrong
brisk mango
"not to use mutables as map keys"
alright
nearly a decade but everything you say is wrong
pathetic
tiny dagger
i think the collision happens when the .equal has to go in a frenzy by checking the insides 🤔
harsh anvil
"If an object’s hashCode() value can change based on its state, then we must be careful when using such objects as keys in hash-based collections to ensure that we don’t allow their state to change when they are being used as hash keys. All hash-based collections assume that an object’s hash value does not change while it is in use as a key in the collection. If a key’s hash code were to change while it was in a collection, some unpredictable and confusing consequences could follow. This is usually not a problem in practice — it is not common practice to use a mutable object like a List as a key in a HashMap."
tiny dagger
locations are mutable i think
harsh anvil
i havent tested if the hash changes of an inventory when its content change
torn robin
yes
tiny dagger
like in changing hashcode
torn robin
unfortunately so
harsh anvil
but if thats the case then you should most definitely not use them as keys
worn temple
It does, back in my early dumb days I used it as a key, and would run into lots of issues
brisk mango
well but no one was using here a List as a key lol
worn temple
Inventory hash does change tho
So, using it as a key doesn't work
And you keep saying to use it as a key
tiny dagger
i think don't think they handle hashcode anymore in inventories
harsh anvil
then that would mean it changes every time something about the object changes
harsh anvil
what class is that?
tiny dagger
craftinventory
harsh anvil
what does hashcode from inventory return?
tiny dagger
the java hashcode
harsh anvil
alright
@brisk mango you could always try it out and see, get an inventory hash, add some itmes to it, see if the hash is the same after
but from what i can tell it should change
worn temple
I can say safely it does change because its lead to issues in my super super old plugins from when i got into java.
tiny dagger
well i don't see anything now related to it
so it probabily got removed in time
because i see the legacy call of it
like they did something to it and kept it overrided for some reason
harsh anvil
Actually seems like i'm wrong after doing some research and asking some people. The hashcode is only generated once and cached. So it will not change when the contents of said object change. Unless the hashcode method is overriden @worn temple @brisk mango
worn temple
Maybe, I know it at least was overridden at some point in time. Don't know if it is anymore. Point still stands tho that mutable objects shouldn't be used as keys

because of while loops

if i shoot into the air
the game stops proccesing until the target hits
the runnables arent changin that
nimble stump
So you still have a big while loop on the main thread
worn temple
^
Yeah, clearly you aren't using runnables or aren't using them correctly.
Because not processing is caused by locking up the main server thread
tiny dagger
@limber sierra version?
nimble stump
We really need to see the code to help you at this point

if((cooldown.get(me) + 5) >= (System.currentTimeMillis()/1000)) {
ItemStack stuff = e.getItem();
ItemMeta em = stuff.getItemMeta();
em.setCustomModelData(3);
em.setUnbreakable(true);
em.setLocalizedName("Staff1");
stuff.setItemMeta(im);
me.getItemInHand().setItemMeta(em);
me.updateInventory();
loc = loc.add(loc.getDirection());
new BukkitRunnable(){
@Override

}
}
}}.run();
}
Use codeblocks or upload that mess to haste/pastebin
its impossibel to read hrere
but Just from that, you're doing that wrong
hollow thorn
worn temple
possibly not the exact method you need, but that's how you should be using it, because right now you are just blocking the main thread

is there any way to use BukkitRunnable
worn temple
I literally just linked how to

are you sure thats the right link
worn temple
hollow thorn
thats just telling me how to use delays

also how do i get the plugin

Hi guys I'm new to using Maven and am trying to use a Google Cloud dependency with my plugin. I wish to "shade" the external jars into my plugin, as I'm getting NoClassDefFoundError.
This is what one of the google cloud dependencies looks like:
<dependency>
<groupId>com.google.auth</groupId>
<artifactId>google-auth-library-oauth2-http</artifactId>
<version>0.20.0</version>

How do I shade this into my plugin? I've looked around and got this so far, but am unsure what parts need to go where...
<plugin>

Hello guys! Can someone explain me how to setup fallback server? I have searched a lot in the internet and tried to set the priorities in the bungee config but doesn't work. When the "survival" for example is shut down doesn't get me to the lobby, it only shows "Server closed." and thats it
worn temple
https://www.spigotmc.org/wiki/bungeecord-configuration-guide/
If you are using forced hosts, it will bypass the default server configuration
manic raptor
Sorry to tag you @subtle blade but you've been impeccably helpful in the past and was hoping would you be able to help me out with Maven dependencies?
This is my first time using Maven, or a plugin with a dependency. I'm trying to use some Google Cloud PubSub functionality in a plugin, and can't seem to get the dependencies right. I'm using Maven and Intellij.
Using these imports...
import com.google.api.gax.core.FixedCredentialsProvider;
import com.google.auth.oauth2.GoogleCredentials;
import com.google.cloud.pubsub.v1.AckReplyConsumer;
import com.google.cloud.pubsub.v1.MessageReceiver;
import com.google.cloud.pubsub.v1.Subscriber;
import com.google.common.collect.Lists;
import com.google.pubsub.v1.ProjectSubscriptionName;
import com.google.pubsub.v1.PubsubMessage;
I've deduced the depndencies down to...
<dependencies>
<dependency>
<groupId>org.spigotmc</groupId>
<artifactId>spigot-api</artifactId>
<version>1.15.2-R0.1-SNAPSHOT</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.google.api</groupId>
<artifactId>gax</artifactId>
<version>1.56.0</version>
</dependency>
<dependency>
<groupId>com.google.auth</groupId>
<artifactId>google-auth-library-oauth2-http</artifactId>
<version>0.20.0</version>
</dependency>
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>google-cloud-pubsub</artifactId>
<version>1.105.1</version>
</dependency>
<dependency>
<groupId>com.google.api.grpc</groupId>
<artifactId>proto-google-cloud-pubsub-v1</artifactId>
<version>1.87.1</version>
</dependency>
<dependency>
<groupId>com.google.auth</groupId>
<artifactId>google-auth-library-credentials</artifactId>
<version>0.20.0</version>
</dependency>
</dependencies>
And I'm trying to shade them in with...
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.2.1</version>
<executions>
<execution>
<phase>package</phase>

<include>com.google.cloud:google-cloud-pubsub</include>
<include>com.google.api.grpc:proto-google-cloud-pubsub-v1</include>
</includes>
</artifactSet>
</configuration>
</execution>
</executions>
</plugin>
But I still get NoClassDefFoundError exceptions for classes that I'm not explicitely using, but are a part of the classes I am using. :/
I tracked them down one by one, adding dependencies to NoClassDefFoundError exceptions and eliminating them one by one until I hit a roadblock where I got completely different Gcloud related errors most likely from other missing dependencies that it's not naming... :/
I guess what I'm looking for is like, an "include this class, and shade in all classes or jars related to this one." type of thing? I'm very new to Maven, literally only just started using it today and can't figure it out :/
I should also note that when I simply run the code I'm trying to run it works fine, just doesn't work when running it in a plugin on a server. If anyone else is able to offer a hand it would be greatly appreciated. Also sorry for the loong message.

No, what command
manic raptor
Using intellij, I'm just double clicking the package cog on the right
please don't hurt me im a retarded noob
wanton delta
Have you tried to click the Build > Rebuild Project button?
sometimes that fixes weird maven issues for me
second thing i would try is running mvn clean install
wanton delta
true
worn temple
building with IJ shouldn't be used if you are using a dependency manager unless you configure it to build with your dep manager
manic raptor
I'm sorry I'm really not sure what that means.
Is mvn clean install run on the command line? Or is there a place in intellij that you run such commands?
wanton delta
Rebuild Project is perfectly acceptable, it solves a lot of weird issues ive had with maven
worn temple
yes, its on the command line
manic raptor
kk, I don't think i have the path configured
worn temple
You need to install Maven, and then restart your IDE
manic raptor
alrighty
So just to confirm, this will most likely solve my issues? Or atleast, it should technically include all of the missing classes once I do this? (assuming the dependencies to all the import statements are correct?)
worn temple
once you do that, go to the little terminal window mart said, and run mvn clean package and you will have a target folder with the .jar file. Assuming maven is configured correctly, it'll work
wanton delta
dont speak in absolutes
manic raptor
Alrighty so @worn temple, @wanton delta
thanks for the assistance so far.
Installed it and ran the command okay, but getting "No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?" :/
wanton delta
where does your JAVA_HOME variable point
manic raptor
Okay nevermind!! I just hadn't set the JAVA_HOME variable! 😄

@worn temple @wanton delta
Ran the command successfully and am still getting the same NoClassDefFoundError exceptions. :/
Is there an option with the shade plugin to "shade every class that has to do with this one?"
golden vault
?
red estuary
can u open dm i need help with resource
golden vault
you need help doing what with a resource?
worn temple
@manic raptor Check to see if its in the jar, I'm not sure what shading stuff you are doing since I've never needed that kind of thing, like ever, and have not had issues with maven packing in my deps.

I have to tell you privately, it is something with my premium resource

Ok so my server got hacked due to bungeecord issues. We fixed everything except the balances. They gave everyone $600k, but when I do /eco take ** 600000 it only took it from about 100 people before it said inssuficient funds
What could cause this?
Is there a way to roll back the economy?
manic raptor
@wanton delta @worn temple
The class calling the NoClassDefFoundError exception isn't in there. :/
worn temple
Put you maven file on hastebin/pastebin and link it, I'll see if I can see anything that looks odd
worn temple
Try just doing ```xml
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
for the shade instead. spigot won't get pulled in since its marked as provided. do `mvn clean package` again and see if its in the compiled jar(ignore the formatting, pulled it from a badly formatted file)
Also, why are you compiling on j6? even mojang dropped support for j7 and below with 1.12
manic raptor
@worn temple It's looking good so far actually!! Server's crashing though but I think that's because my code is waiting for a PubSub message. I'm just gonna make it run on a different thread and will let you know.
I wasn't intending to compile/run on java 6. Im pretty sure its compiling on 8 because the jdk is a 1.8 one. Intellij added that automatically and it solved a problem where I couldn't put @Override on top of implemented methods.
worn temple
Should be able to bump that up and not have an issue. if IJ is configured to import the maven pom for the project correctly, it'll use that for deciding what stuff to allow, so it would yell at you for using lambdas since it thinks you're on j6. Anyway, getting off point.
Good, that would be what's crashing it, since pub/sub systems using websockets always block until a connection is received. So you'd need to offload it to different threads and then sync it back onto the main server thread should you want to interact with the bukkit api on some action
manic raptor
Mmmm, it's crashing even before it gets to the pubsub stuff and it's on a different thread. The server won't even start because of "Invalid signature file figest for Manifest main attributes" from java.lang.SecurityException
worn temple
What's the full error?

Is it possible to prevent the showing of items in a PrepareCraftItemEvent now

@worn temple sorry, didn't see ur message https://pastebin.com/HatjNMmy
...found this:
https://stackoverflow.com/questions/34855649/invalid-signature-file-digest-for-manifest-main-attributes-exception-while-tryin
And the top answer makes sense kind of. I'm not sure if this is what I need to do though (disclude any "signed" jars)
worn temple
Yeah, don't know which jar is signed tho... This may work: https://stackoverflow.com/questions/999489/invalid-signature-file-when-attempting-to-run-a-jar/6743609#6743609
You're basically telling maven not to include these sig files in the compiled output. I am curious what dep is signed, since I've never really run into one with google deps (I made a massive discord bot that hooks into the google calendar api).
It may be gax (no idea what that is tbh). The others all look pretty normal, and the auth libs seem fine too since I have a few of those in my projects
Honestly, this is a bit out of my usual skill set since I've never had an issue like this in particular.

Is anyone willing to help set up Voting Plugin with nuVotifier?
pastel condor
It shouldn’t be hard at all, simply make a vote on a site and it will he added to your vote sites file
rain plank
Uh, I've tried... multiple times, it doesnt seem to work.
I even uninstalled and re-installed.
radiant pollen
What voting plugin do you use with it?
worn temple
Is the port it needs open? assuming it uses the same standard made by Votifier, you need to open a port in order to receive the votes.
rain plank
"Voting Plugin"
dusty topaz
Any reason why CraftingInventory#setResult() is not ... setting the result lol
the itemstack I'm passing in is not null
worn temple
@rain plank is nuvotifier set up correctly? That's likely the root of the issue.
worn temple
Are there errors? Hard to help when "doesn't seem to work" can mean many many things. What doesn't work, what are you doing? what is the expected outcome? etc.
rain plank
when we vote, it's not calculating and giving rewards.
Not sure what's really that hard to comprehend in that.
lol
worn temple
Its not that I don't understand it, its that there are many different things at play and I'm just trying to narrow down the issue. Are there errors?
rain plank
No.
worn temple
Is nuVotifier correctly picking up the votes? if so, its likely a configuration issue with VotingPlugin
rain plank
I just re-installed that yesterday bc nuvotifier wasn't installed correctly.
worn temple
Okay, but is it picking up the votes? If its not, its nuVotifier causing the issue. If it is, its probably VotingPlugin. You see why I was asking so many questions now? There's a lot of things it can be that we can't know with limited information
rain plank
That's why I'm asking for some one to check the configs for both.
"help me set up"
lol?
I already said that it's not picking up votes, why are you being redundant.
worn temple
But its probably not a config issue, it takes no configuration changes to receive the vote. So my original assumption is probably correct: Do you not have the port open?
rain plank
the port is open.
worn temple
For the router and the firewall? (assuming you are either self hosting at home or on a vps)
rain plank
Yes.
worn temple
And you are sure the server list site has the correct port for your server? (they can be changed in the listing settings)
rain plank
Yes.
radiant pollen
Usually voting sites will send a test vote whenever you update the listing's info. Does NuVotifier log anything when you update a listing?
worn temple
Are you sure NuVotifier is even loading on server boot?
I mean, it should be just plug and play
frigid ember

@frigid ember All you have to transfer is world folders, plugin folders, and the configuration yml files.
frigid ember
aha thanks
radiant pollen
Unless you have a MySQL database or some other thing... that should be pretty much it.
@rain plank What happens when you use this? https://mctools.org/votifier-tester
It should always log at least something.
If nothing is logged, NuVotifier didn't load properly; the port is closed or something.
rain plank
says that i voted.
radiant pollen
So NuVotifier is setup correctly.
That's what you weren't telling us.
If it logs that a vote happened, then NuVotifier is working. The issue is with VotingPlugin because votes are being registered but no one is getting rewards.
worn temple
That's what I was finally looking for omg. Thanks for getting to the point Zax
stoic sundial
anyone knows working non abusable /f shield ? :/
rain plank
I told you it wasn't nuvotifier. omg.
worn temple
No, you said it wasn't working before and you reinstalled it. You never confirmed if votes were being received like I asked 3 times.
So its probably VotingPlugin not loading correctly on start up, or a config issue.
worn temple
looool
¯_(ツ)_/¯
I try not to spoon feed, but when they play dumb, you just gotta play dumb back
pastel condor
When you spoon feed them but they don’t understand.
worn temple
yeee
I was just trying to figure out if votes were being received and processed correctly just so we can ignore that part of it all and handle the reward plugin lol
pastel condor
Lol

Need help, someone knows how to export and import with phpMyAdmin?
gaunt thorn
Anyone able to point me in the right direction? Trying to grab a certain inventory with a colored name instead of just the string of the name. Having an issue with translateAlternateColorCodes saying ChatColor is not applicable for the arguments (but it use to be ages ago)
keen compass
as you can see, it takes a char and boolean not a char and string
but your IDE is just playing tricks on you though
it is correct to use char and string not sure why your IDE is complaining or stating otherwise lol
worn temple
don't use eclipse, use intelliJ
for eclipse you probably have to do String#toChar to get it to play nice since eclipse is hella dumb
barren abyss
White IDE = 
gaunt thorn
Who has a white IDE?
worn temple
Actually, @keen compass @gaunt thorn That's not correct, you are doing char, boolean. You need char, string. #contains is a boolean
So... you have your parans () messed up
gaunt thorn
How would I check if the title has the correct chatcolor assigned to it though without using .contains or .equals?
worn temple
Checking the name of the inventory would work, however names can collide. Checking the inventory's viewers would be best. See if the player is in the viewers list of the inventory, and they are, they must be viewing the inventory.
worn temple
I read it wrong as well initially. I don't use that IDE anymore, dropped it nearly a decade ago actually.
keen compass
but I also didn't see that .contains() either
XD
Anyways, nice catch on that where I think most of us missed it 😛
worn temple
My GF saw that the contains was getting passed in when I showed it to her (we both really don't like eclipse and will send each other stuff about how bad it is) and she said that it was seeing it all correctly.
keen compass
I was half wrong then 😉
worn temple
only half, so nice job!
keen compass
I was just wrong about what the IDE was stating but was correct about the API
But yeah, still a nice catch though
I use Eclipse and in Eclipse when you highlight something that is wrong like that
it will explain in depth what is actually incorrect about it lol
worn temple
Its why I love rainbow brackets for IJ, makes this easy to read https://owo.oooooooooooooo.ooo/i/945a.png

so I recently found the entire source for CB that I had XD
CB and bukkit, so I have all the versions going back to the first release 😛
worn temple
I have 1.7.10-1.13 all hosted on a private repo only I can access
keen compass
I am not worried if I put something up and its private or not
worst that happens is someone mails me a DMCA lmao
worn temple
Needed it for plugins that require NMS code, notably my library that abstracts it all so plugins can work with multiple versions and not need to worry about nms nonsense
worn temple
What software? never seen it before actually
keen compass
Just maven
when you use maven-deploy it will setup the directories appropriately for you, as for the theme its just apaxy
So, all you are seeing is a maven repo
worn temple
Ah, I prefer nexus, finer grain control over everything. Including keeping stuff private (like my CB builds and plugin APIs that aren't on maven) and for my APIs
keen compass
for me to make something private its just a matter of just modifying the .htaccess file lol

@golden vault You mind helpin me out rq?
I started my server, and saw this error message:
[TAB] Group "owner" is not defined in sorting list! This will result in players in that group not being sorted correctly. To fix this, add group "owner" into group-sorting-priority-list in config.yml.
I don't suppose you would know how to fix this problem? I have tried a few things, but none of it worked. I am unsure of what to do now.
Thanks in advance!
worn temple
stop server, add owner to group, start server. Should do it
golden vault
Ya, idk what ever TAB is, a tablist i assume, you will need to follow their documentation.
wet otter
Alright. Thanks for trying Weaves.
@worn temple the group: owner is already in the group-priority-sorting-list

Hello, does anybody know if there is a placeholder that returns if the server is Online, Offline or Whitelisted. Like %pinger_isonline_testplugins.com:25565% but it only returns Online/Offline. Is there one that checks if the server ip is whitelisted or not? So I can create a ph that combines all three
frigid ember
@worn temple Hi 😁 Long time no see
worn temple
@wet otter Is it there for all the servers and everything? I usually see tab plugins act up when its a bungee tab plugin. Otherwise I couldn't say. Are you making sure to shutdown the server and then edit the file? because some plugins write to file on shutdown and "erase" user changes.
@frigid ember Hey, I'm bad with names so remind me?

Yes

Its really hard to help you when you aren't giving information. If you could copy/paste what you typed to make it happen, we may be able to offer more help. But we know nothing other than you entered a command and don't know what you typed, and now see this.
wet otter
@blissful trench Are you still logged into the server? If so you could probably just press T and then the ⬆️ on your keyboard until you find the command you've typed. If you can't, you should probably message a server staff or the owner directly, as they will likely have more information.

@wet otter I can't do that anymore. because I've already come out and i've gone in again
wet otter
Then your best best is to message a staff member/server owner directly.
We can't help you without further information. Which we don't have.

so, contact the server staff. This server is more for help for server owners/developers.

I'm going to do this more carefully. Then I come into contact with them

although I've ever read that

but I just don't have time
when your random number generator is the last digit of used ram
you know theres something wrong
sturdy oar
yeah it could pretty much be the same several times
pastel condor
really?
sturdy oar
they use
srand(time(NULL))
wow
sturdy oar
well java definetively ain't using the current time to generate random numbers
that would be baaaad
nimble stump
“yeah it could pretty much be the same several times”
In the case of a true random number generator, which we have not been able to create yet, that would still be true
Random means random, not “different every time”
sturdy oar
i know but with time, the odds of having similar numbers are increased
even Clion will flag that if you do it
nimble stump
Predictable sequence means you can guess the next numbers with a strong likelihood
For example seeding with a constant
nimble stump
Seeding with the current time isn’t that bad if you want PRNG
You’ll get a different sequence every time you run
hollow owl
How can I make a switch, so when I choose a block to get that block from the config

sturdy oar
they might have to rewrite some of their code if they upgrade to Java 11
keen compass
it would be nice if they would jump to java 14
keen compass
They actually don't need to re-write anything since all the way to java 14, java 8 bytecode is supported
hoary parcel
There is even java 9+ only code in there already
Or was that paper code, now I don't remember
The whole cleaner thing for pooling
tawdry venture
then what about releasing 1.16 with the latest java?
keen compass
the only problem with them supporting later versions after java 8
is that they need to ship their own JFX or whatever
since that was removed from the JRE
tawdry venture
do mc uses jfx?
bronze marten
They use javafx???
hoary parcel
If you compile on 11 you need to change of bunch of things
But that isn't required for shipping
They could just ship a new version in the launcher, see how it goes and later change the compile target
tawdry venture
what about bundling the jre?
hoary parcel
They do that?
keen compass
they already do that if you don't have java installed
or use a version that isn't directly supported

const is for values that are already known at compile time

You can also use final for those

final just makes sure the reference can't be re-assigned

Okay so I'm having issues with chunks saving in my overworld.. It always happens at villages, seemingly only while villagers are spawned
https://pastebin.com/XQJZxJdY
the full save error is there
Any help with that would be greatly appreciated, this has been happening for a few days now and I really don't know what to do about it
naive goblet
it's mainly maintained because many developers like how it works more than java
sturdy oar
the only issues i had with Kotlin were binary operators being weird
naive goblet
Eventually kotlin can be pretty nice for core
But I mean doing frameworks or libs then you should probably stick to java?
pastel condor
K
naive goblet
Mostly just preferences
sturdy oar
you have to consider that when you use kotlin, you need to have the Kotlin Stdlib
otherwise it won't run
keen compass
@terse schooner do you have any plugins that mess with entities?
nimble stump
Or their NBT
terse schooner
The only potential candidate should be mythic mobs, but it's 1.15.2 stable and has no effect on vanilla villagers
keen compass
doesn't mean it can't be causing it. The problem the server is reporting is that it can't save entities
because something about the entity is null
nimble stump
Every village or specific types of village
keen compass
should test without that plugin to see if the server saves just fine
odds are it will
nimble stump
How reproducible is it
Does it happen whenever you try to save a village chunk or only sometimes
keen compass
accordingly from the OP it happens everytime whenever there is villagers spawned
in villages
nimble stump
Seems easy to test that theory then

Is there a way to delete the default world w/o affecting inventories of players?
silver pewter
You can if you store all their data into a config then grab it in the other world like /store and /restore
keen compass
just delete everyting in the world directory except the one that says playerdata
abstract knoll
Kk, so I can transfer the playerdata to another existing world's folder, then set it's name as the world in both multicraft and server.properties?
keen compass
just copy the playerdata to another directory and it should work fine, as usualy make backups first
in case it doesn't work out for whatever reason
abstract knoll
alrighty, thanks a ton c:
nimble stump
That will probably put them in the same coordinates in the new world though
Unless you have an auto spawn plugin
abstract knoll
it's all g, the old world was never used - does it delete data from chests as well?
nimble stump
Chests are stored in the world, not in the player data
Wait, if the old world was never used why are you worried about player inventories?
Surely there wouldn’t be any data?
abstract knoll
for some reason, all playerdata is stored in that world
other worlds have empty folders for playerdata
abstract knoll
Kk thanks, this is a bit worrying
abstract knoll
I transferred it tho, hmm maybe instead of transferring it made a duplicate

Arite lads
so my servers are crashing, moved over to a small host
and it's whenever there's sqlite activity
are there usually any sqlite libraries that i can download for stuff to not crash?
obtuse rose
maybe check what's wrong with sqlite file first?
torn willow
Uh my account is saying its been verified already, what do i do?
limber sierra
it's not just one plugin
that's the issue
it's whatever uses sqlite
e.g. Statz, AuctionHouse-Legacy, Jobs, etc
I've disabled Statz as that records everything you do
but whenever something is auctioned off or whenever someone starts a job, it crashes
and all three of them relate to whenever the sqlite db is being updated
is there some kind of lib that I should apt-get, or?
keen compass
@abstract knoll I should note ender chest data I believe is also stored in the player data files.
limber sierra

Spigot has SQLite drivers shaded in

@keen compass thanks! which though the .dat or .json

what Spigot version
limber sierra
1.12.2
keen compass
probably both, not entirely sure @abstract knoll those are files I normally don't mess with lol
obtuse rose
pretty sure it's .dat file
keen compass
I think so too
obtuse rose
Minecraft's .dat is gzip compressed nbt data
abstract knoll
so far I still have my stuff so I hope it's all g c:
makes me wonder what's in the .json ones tho 🤔
keen compass
if I recall contains players last location, bed spawn location etc
open it, its just a json file
should be readable
the .dat file isn't readable and would require an NBT reader to view it
abstract knoll
gotcha,so it's just localized into the world then (except the bed stuff)
keen compass
abstract knoll
I kinda removed it alr so big rip
keen compass
use that site if you want to see what is in the .dat file
limber sierra
what Spigot version
@sturdy oar more specifically:
This server is running Paper version git-Paper-1618 (MC: 1.12.2) (Implementing API version 1.12.2-R0.1-SNAPSHOT)
Checking version, please wait...
You are running the latest version
well, that isn't spigot per-se
however you are also on an outdated version
also it sounds like your problem is I/O related
keen compass
it could be that the host you went with has too many other VPS's on the same box as your VPS
Which is causing I/O for you to be horrible
limber sierra
it just doesn't really make sense though :/ it's only sqlite databases
E.g. I switched SpleefX to write from a db into flatfiles, and that turned out all fine
keen compass
did they allow you to upload your own jars for the server? or do they provide one for you?
obtuse rose
you need more than horrible IO to break SQlite though 🤔
limber sierra
They allow me to upload jars
keen compass
does it throw any errors?
limber sierra
Apart from the crash, no
It creates a fat 1gb core dump and slaps a crash log in my directory
keen compass
then the only thing I can think of is that there is so much data that sqlite just can't keep up with it. Or they are all trying to use the same DB
?paste
worldly heathBOT
keen compass
paste the crash log
it sometimes contains helpful stuff
core dump is helpful if you have a heap dump viewer
you can see what the server was doing just before it crashed
But that crash log would be helpful too
keen compass
heap dump doesn't always correlate to the allocated amount of ram @obtuse rose especially if the ram allocated is dynamically set. That is the initial heap size is not set to the same size as the max
in that case it will only dump what was being used
tiny dagger
how would i go about on creating a snapshot of the attributes? 🤔
i was thinking about enum map attribute base value
but i'm not sure if that's good
limber sierra
But that crash log would be helpful too
@keen compass https://paste.md-5.net/obufahomuh.makefile
keen compass
well, interesting you start the server with just 128M
probably should start with a bigger allocation lol
obtuse rose
that shouldn't be the problem though
limber sierra
^^
obtuse rose
that problem would goes away when JVM warms up
limber sierra
i mean
i'm p sure startup memory isn't causing the sqlite problem :S
but i'll change the startup memory
keen compass
well the last thing that was doing anything with SQLite is leaderheads
obtuse rose
It's segmentation fault
it doesn't matter what plugin do what
@limber sierra is it running in docker?
Pterodactyl?
keen compass
that would probably explain some problems
SQLite shouldn't generally cause the JVM to crash
at least not directly
Application crash sure, but a JVM crash is usually more serious though XD
limber sierra
so a segmentation error?
obtuse rose
@limber sierra what hosting is it if I may ask?
limber sierra
i mean, could it possibly be because of permissions in server files?
real small one, used them for a little while though with vpses
keen compass
only thing I can think of that would cause that is docker not playing nice or a memory module starting to fail
crisp nest
guys where can i find a shop plugin for 1.14.4?
keen compass
kernel could probably do it, but I am not familiar enough with alpine linux
limber sierra
guys where can i find a shop plugin for 1.14.4?
@crisp nest on google
keen compass
its possible alpine linux and docker don't play well together
which could result in segmentation faults
crisp nest
i know bruh
its just that the best ones dont show up when i do /plugin
keen compass
Chestshop still exists
and usually gets updated
@limber sierra do you have access to SSH?
or do you have to use that panel to access your files
limber sierra
i have to use the panel
however, i'm working closely with the host team
so i could request whatever
keen compass
That makes more sense, so it probably could be a file perms problem but that doesn't really make sense unless something is setting the perms on those sqlite files
limber sierra
pterodactyl is sftp, so i can edit permissions on them
crisp nest
Chestshop still exists
@keen compass
I dont know how to use it :/
limber sierra
read the instructions
obtuse rose
no, pterodactyl set all files permission when server start
keen compass
it has a very thorough documentation for it
obtuse rose
Unlikely to be pterodactyl problem imo
start with updating docker and kernel might be something you should try @limber sierra
keen compass
But it doesn't make sense there would be file perm issues on those sqlite files unless something else is interfering with that
@obtuse rose they don't have access to the VPS
keen compass
that is fine
limber sierra
even when it recreates and tries to update, it still crashes
obtuse rose
ah so the "hosting team" means the hosting company?
keen compass
so do they give you a docker container or is the docker container running inside the VPS?
limber sierra
they give me a docker container
keen compass
Sounds more like hardware failure then
but can't know for sure because you don't have access to the files that would indicate as such or perform any tests to know
I would give your hosting provider that crash log
and ask them if they could check the hardware to rule out hardware problems
keen compass
docker isn't like normal VM's so it makes use of the underlying host hardware
but either it is a docker problem or a host hardware problem. That is about much info I can give, but that is only because you are only able to give limited info as well. Hopefully your hosting provider helps out.
crisp nest
so i am trying i did the tutorial but, it doesnt work (sorry but im new to plugins)
keen compass
Yes I am aware kernel does exist however this is a docker container so the OS in the container shouldn't be the issue. It could be the kernel on the host but odds are it isn't either. But segfault means memory was being read/wrote to in an illegal location
and this is the JVM that crashed, not the application, so there isn't very many things that can cause the JVM itself to segfault.
in all cases of what caused it, its outside of this persons capability to fix it
obtuse rose
illegal location, do you know what of the cause that make the location illegal?
the freaking kernel deny access to it 😒
keen compass
Or the location is no longer valid because of memory module failing
silk gate
send the dump
obtuse rose
yea let's forget about kernel which is more common segfault cause and skip to hardware okay
keen compass
Anyways regardless like I said, the hosting provider will have to fix it

@silk gate
I am going with HW because it isn't very common for the kernel to freak out about the JVM
something has to have caused the JVM to attempt to access an illegal location
silk gate
it's a mission for JNI to not crash the jvm
keen compass
So, the only thing that comes to mind where I have rarely seen it, is a memory module failing
silk gate
yeah does look like dead ram
obtuse rose
but that's quite rare though
silk gate
it happens
keen compass
it is, but it does happen
silk gate
I've had a dead ram stick
obtuse rose
would need to reconsider hosting company xD
silk gate
no he wouldnt
keen compass
it may not be their fault
silk gate
dead ram can happen to anyone
keen compass
hardware fails all the time
all that needs to happen is for them to locate the dead ram card
and replace it
and then all is good
its more common for ram to go bad in servers then it is for desktops is because servers are generally running 24/7. Where as most desktops don't run 24/7 and don't run as extensively as servers do either.
obtuse rose
although I would expect better maintainance, but yea could be bad timings happens I guess
keen compass
can't really predict when they will go bad
even with good maintenance
they can still die XD
limber sierra
"The kernel and docker are updated frequently"
just got that from the hosting provider
obtuse rose
then it's hardware
keen compass
Figured it wouldn't be the kernel or docker. But never hurts to check as that is the easiest 😉
core dump looks a lot similar to one I had looked at that was a memory module failing
boreal bramble
Do any of you know SQLite database? I got a problem with it.
Method org/sqlite/RS.isClosed()Z is abstract
What should I do for it?
SQLMain.java (OnPlayerJoin Event): https://hasteb.in/udofezaj.java
SQLBase.java (SQL Methods): https://hasteb.in/vejiwire.java

@obtuse rose speaking of which - should i get timing reportings, if that helps?
obtuse rose
nah
keen compass
its not going to help in this case
obtuse rose
whatever had failed, your hosting company is the one who have to take care of it
core dump looks a lot similar to one I had looked at that was a memory module failing
@keen compass segfault dump looks the same though? 🤔
keen compass
well its a core dump, just means the JVM crashed. But they don't all look the same
Usually when the core dump doesn't make sense in why it attempted to access an illegal memory location. One of two things happened. Either the kernel freaked out which is rare unless you are using a kernel that isn't common to use which in this case isn't the case as they are using alpine linux as well as the OS contained in docker. So that means docker would have attempted to access an illegal memory location, but if that happened docker would have crashed as well which doesn't appear to have happened. Or the memory module is failing and the location it wanted simply according to the host no longer exists because it can't be accessed IE it died or just lost the information it was suppose to contain.
obtuse rose

I am saying that statement is false, because you can't tell what cause segfault by looking at core dump
lilac quarry
how can I reduce an ores experience point
For example if player mines lapis ore I want to give 0 exp
obtuse rose
@lilac quarry change it in BlockBreakEvent
keen compass
@obtuse rose but then how did I correctly suspected it was HW then? o.O
they won't be completely the same
but they will share similarities
lilac quarry
Where can I find the BlockBreakEvent?
pallid arch
where can I find the plugin othedrop on version mc 1.15.2 ?
lilac quarry
@obtuse rose I don't know anything about BlockBreakEvent, How can I do?
idle zodiac
How can I listen for the equipping of Armor in spigot 1.8.8?

How can I listen for the equipping of Armor in spigot 1.8.8?
@idle zodiac you can check wich slot have an item
idle zodiac
@barren abyss Should I put that in a Loop?
barren abyss
Neh, theres probably an easy way let me see
idle zodiac
thanks lopl
barren abyss
You just want to check if he put on the armor?
barren abyss
I think you can do it with InventoryMoveEvent
barren abyss
You can probably check if the item [Material.LEATHER_HELMET] has been moved to head slot and do stuff then
idle zodiac
I can't get the player name from that
barren abyss
Im sure you can
barren abyss
oh..
limber sierra
whatever had failed, your hosting company is the one who have to take care of it
@obtuse rose @keen compass the hosting company have taken a look at the sqlite plugins on a test server, and it seems to all be fine apparently (just tried on regular spigot 1.12.2 as well)
Edit: never mind
barren abyss
whos playing 1.8 in 2020?
idle zodiac
Me
limber sierra
me

Also literally everyone on the hypixel network

barren abyss
oh yeh, they have those minigames right?
idle zodiac
?
barren abyss
I don't play that much minecraft
barren abyss
just make plugins for people tho
idle zodiac
Cool
barren abyss
Maybe check armor on player?(no idea if its possible)
It look so tricky can't find an easy way to do it ..
idle zodiac
Ye...
If that isnt possible
Is there a way with 1.8 NMS to alter the amount of defence points a player has?
silk gate
I am saying that statement is false, because you can't tell what cause segfault by looking at core dump
@obtuse rose sir that is the point of a core dump
idle zodiac
i just realised i didnt have an eventhandler i am so stupid kill me now
barren abyss
idle zodiac
it still doesnt work
obtuse rose
@silk gate
SIGSEGV - segmentation fault
SEGV_MAPERR - address not mapped to object
But it doesn't explicitly tell you what cause SEGV_MAPERR
The rest is the running process, data in the stack etc etc
silk gate
@obtuse rose yeah and by reading that you can figure out whats going on
silk gate
having a ton of unknown values in registers points to a faulty memory module
obtuse rose
it still in a process, even if it's in a docker
it won't get access to entire docker memory
silk gate
yeah but dockers ideology is single process per container
so it's really unlikely
also brb phone 1%
obtuse rose
trust me, process in docker doesn't get entire docker memory access
silk gate
yeah ofc
but
whats the likelihood that another process has magically been given that memory
obtuse rose
quite a lot actually
I just start up minecraft server
notice that it's scattered into multiple places
keen compass
now take a heapdump of that process and see if any registers come up as unknown
keen compass
file permissions can cause a segfault, but that doesn't explain unknown values in registers or empty registers. It is possible that it could be the sqlite library if its happening in the native library, but according to this core dump, its happening outside of JVM control so not the library being loaded. We can see all the libraries being loaded just fine actually even the sqlite one. It could be a problem with semaphores but highly unlikely.
An outside process could have caused it, but then that would be a question of, what process was running in the docker that tried to access JVM memory
obtuse rose
@silk gate you'll find the same result in a running docker, it still share memory pool with it's host
although I am not willing to spin up docker to show this, you're welcome to test it by yourself though 🤷♀️
turbid latch
org.bukkit.craftbukkit.v1_15_R1.CraftWorld cannot be cast to com.sk89q.worldedit.world.World
what should i do to get worldedit's world?
keen compass
however, it will have mapped memory for its specific use, and the processes inside docker would use that mapped address space that docker created
if something from the outside attempted to access dockers memory space, the docker container would have crashed and not just the JVM
subtle blade
WorldEdit has Bukkit adapters
Class is like BukkitAdapter or something. Some static methods to convert
keen compass
the only other possibility would be a buffer overflow
but interesting that the JVM or docker would be creating that
silk gate
a buffer overflow in the sqlite lib wouldve been discovered long ago
turbid latch
i did this but it is wrong
final EditSession editSession = WorldEdit.getInstance().getEditSessionFactory().getEditSession((World) p.getWorld(), -1);
silk gate
its jni, no?
