#

well what should be the best

nocturne elbow Jul 17, 2022, 11:41 AM

#

getting it as a local variable is not recommended

muted acorn Jul 17, 2022, 11:41 AM

#

why

nocturne elbow Jul 17, 2022, 11:41 AM

#

since this can fuck up things if you're working on different threads

#

not sure if luckperms has thread safety

muted acorn Jul 17, 2022, 11:41 AM

#

goddamn it

#

AHHAHAHA

#

so many things

#

okay

#

and how should i get player rank for example

nocturne elbow Jul 17, 2022, 11:42 AM

#

User#getPrimaryGroup()

#

then use GroupManager#getGroup(String primaryGroupName)

muted acorn Jul 17, 2022, 11:43 AM

#

yeah

#

ill figure it out first to find user hahahtard

LuckPerms - A permissions plugin for Minecraft servers.

LuckPerms

LuckPerms is a permissions plugin for Minecraft servers. It allows server admins to control what features players can use by creating groups and assigning permissions.

#

Has LuckPerms been exploited/hacked?

Most certainly: no. In most cases a 'LuckPerms exploit' is a simple case of human error, which can be avoided easily. Look below for some tips to be on the safe side.

Don't give random people full ( * ) permissions / admin permissions

While this should be obvious, a lot of times a exploit can be traced back to faulty permission settings. You should always take your time with permissions and read the plugin documentations. In 99% of all cases the plugins have documentations explaining each permission, in the rare case that the plugin you are using does not have a documentation, you could still:
A: Ask the plugin developer for help
B: Use LuckPerms verbose functionality ( !verbose )
C: Select a different plugin with proper documentation.

Do not run your server/network in offline mode

If you are running your server or network in offline mode, hackers have it really easy to steal your, or any other admins identity. While the server is in offline mode, certain checks ( which exist to prevent exactly this ), are being skipped, and the server does not verify if the person joining actually is the person they claim to be. While there may be plugins which increase the security of offline mode servers by adding things such as admin codes, you should just switch it to online to prevent the issue in the first place.

Do not download plugins from shady websites / sent by friends

You should never put anything on your server which has not been downloaded by yourself from official sources. Plugins can be infected with malware which injects itself into all other plugins, and thus is hard to remove. While it may look like a plugin has been hacked, you most certainly downloaded a modified version of it and it is not the plugin authors fault. In case your server has been infected by such malware:

Stop the server
Delete all plugins in your plugins folder, and just to be safe also the server jar file
Re-Download all plugins and server jar files from official websites such as SpigotMC or official plugin websites ( luckperms.net for example ).
Check if there have been any modifications to the permission system and remove unknown users and wrong permissions.
if you follow these steps you should have a clean server by the end, without exploits.

Hey guys

#

when i try to load a user

#

from LuckPerms

#

and the user is offline

#

it can't load it

#

it returns null

#

@Override
    public @NonNull Group getPrimaryGroup() {

        AtomicReference<Group> group = new AtomicReference<>(null);
        this.toLuckPermsUser().whenComplete((user, throwable) -> {
            if (throwable != null) {
                throwable.printStackTrace();
                return;
            }
            if(user != null) {
                Group g = LuckPermsProvider.get().getGroupManager().getGroup(user.getPrimaryGroup());
                group.set(g);
            }
        });

        return Objects.requireNonNull(group.get());
    }

does anyone know the issue ?

this method shouldn't get it from the memory

nocturne elbow Jul 17, 2022, 11:02 PM

#

it loads in a separate thread

#

and the operation might finish in the future

#

but you try to return immediately

#

i ain't putting that in the main thread 😛

#

how can i like sort the tasks

#

even if they're being executed in different threads

#

return a CompletableFuture<Group>

#

or block the main thread until the operation completes shrug

nocturne elbow Jul 17, 2022, 11:04 PM

nocturne elbow Jul 17, 2022, 11:04 PM

#

nocturne elbow return a CompletableFuture<Group>

i was actually thinking of that

#

your call, not mine, i'm just giving you options

#

is there a way to make a future callback ?

#

you could also make that function take a Consumer<Group> instead of returning a future<group>

nocturne elbow Jul 17, 2022, 11:05 PM

#

nocturne elbow is there a way to make a future callback ?

yeah that's what completable futures are for

#

thenAccept, thenApply, whenComplete etc

#

ye but like returns the value when it's completed somehow lol

#

nvm

#

if you return a Group, you need to wait until it's completed

#

either return a future or take a consumer which you call in whenComplete

#

is this fine @nocturne elbow

i would recommend breaking from the loop immediately when you assign the hasAccess variable

Mmh Baeldung's guide to CF's is nice https://www.baeldung.com/java-completablefuture and the javadoc can be useful too, although a bit too wordy https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/concurrent/CompletionStage.html
There are a few conference talks online about how to use them, why they're nice etc etc, the ones from this speaker are quite good IMO https://www.youtube.com/results?search_query=venkat+subramaniam+completablefuture

Hello! I'm trying to connect LP to my server's site where users can assign themselves a LP group by clicking a button. So what the best approach to do something like this? Now I'm adding group.some permissions to the lp_user_permissions table. This works fine, but I'm curious how bad this practice is

wild whale Jul 19, 2022, 4:48 AM

#

Well in an ideal world, you'd add the node via our API, LP isn't really designed with external DB modification in mind. I suspect it'll mostly work, but you'd probably need to also send a message via whichever messaging service, or otherwise trigger a resync

ebon vault Jul 19, 2022, 4:57 AM

#

Ah, I see, so the best way is to write a small plugin that can be triggered externally and send updates to the LP API?

wild whale Jul 19, 2022, 4:58 AM

#

that's the ideal method, yes

ebon vault Jul 19, 2022, 5:02 AM

make a copy of the jar, and unzip it. Delete the luckperms folder in net (if there's nothing else in net, you can delete it too)
rezip the files and rename it back to a .jar.

I'm not 100% sure that'll work, but without source code that's the best I can really do short of having to rebuild the entire plugin

Hello!
I have question, which event I need to use to get when user is demoted?
For example:
/lp user Norbiros parent settemp vip 30d
And when user is promoted, I can use UserPromoteEvent, but when that rank will expire, UserDemoteEvent will be executed? Maybe this code: https://github.com/LuckPerms/api-cookbook/blob/master/src/main/java/me/lucko/lpcookbook/listener/PlayerRemovedFromGroupListener.java will work? If no, please tell me how I can detect it

UserPromote/DemoteEvent should only be fired when they're promoted/demoted on a track according to the javadocs
