https://github.com/PaperMC/Folia

Here is a summary of everything made with ChatGPT to save some time:

For plugin developers, there are a few key takeaways from the given text:

1. Folia introduces regionised multithreading, which means that plugins will require modification to function properly. Plugin developers should expect compatibility with existing plugins to be at zero.

2. Folia introduces new API additions, such as the RegionisedScheduler and EntityScheduler, which can help plugins run on the correct thread context.

3. To ensure compatibility with Folia, plugin developers must mark their plugin as compatible by placing "folia-supported: true" in the plugin.yml file. Additionally, plugins must take advantage of the RegionisedScheduler and EntityScheduler API to ensure correct behavior.

4. Plugins should not assume that they can access or modify data in other regions, as Folia regions tick in parallel and do not share data. Plugin developers should take advantage of the upcoming thread-check API to ensure correct behavior.

5. There are currently broken API, including the scoreboard API, and planned API changes, such as super aggressive thread checks, which may impact plugin development.

Overall, plugin developers should be prepared for significant changes in their plugins to ensure compatibility with Folia. They should take advantage of the new API additions and mark their plugin as compatible to ensure correct behavior. Additionally, they should be aware of the limitations and rules of Folia's regionised multithreading to avoid bugs and errors in their plugins.

KauriVPN 1.5.1
I had manually put the config in but I got a Mysql error after updating, so I deleted the config folder and restarted the server and I'm back to this issue. Reporting since it happened in the last version as well and I think something needs fixing.

Running the plugin only on my Proxy server (Velocity 3.0.1)

Is your feature request related to a problem? Please describe.
No way to view allowlist while in game.

Describe the solution you'd like
Add a command like /antivpn allowlist show to allow users with permission to view all entries in the allow list. Maybe use a page format of X entries per page

Describe alternatives you've considered
None

Additional context

Howdy,
Sorry for writing here but I couldn't find another way to contact you. I am interested in your AdvancedAntiVPN plugin, but ported to a C++ application. If you are somehow interested, let me know.
Greetings

Version 1.7 displays an error when starting with a database and doesn't seem to connect to it properly, as it doesn't change anything.

It seems, that the Plugin mixes SQLite with MySql!

It creates two SqLite Databases in a Subfolder KauriVPN/databases, looking at the console output, it probably tries to connect to those and fails as it tries to use it as a MySql Database?! Both of the files can't be opend by the DB Browser (Invalid file format).

Also tested in the 1.6.1 and the Database function worked as intended without an error at startup.

Console Output:

I am using Paper-280 (MC: 1.20.2) and I am not sure if functionality is affected since I do not have a VPN. (What it does do is fill my log.)

Using /antivpn alerts enables the alert for the online session, but when you rejoin the server, the alert is disabled again. The database connection works fine. But it looks like the alert status is not being queried properly by the database. I down't get any errors / warnings in the console.

Version AntiVPN 1.5.2.1 with Waterfall

How to replicate it

1. /avpn alerts --> notifications have been set to: true (ok)
2. Rejoin
3. /avpn alerts --> notifications have been set to: true ( ? )

Hello! I was wondering if storing as a SQLite. H2 etc was possible?

Describe the bug
Using many antiviruses, it throws a false positive when server is loaded

Describe the bug
A clear and concise description of what the bug is.

Servers running on Bukkit/Spigot implementations, that do not halt the JVM will get stuck infinitely when shutting down, due to non-daemon, non-finalizer threads being present.

To Reproduce
Steps to reproduce the behavior:

1. Run the AntiVPN plugin on any Bukkit/Spigot implementation, that does not halt the jvm on stop.
2. Try to stop the server.

Expected behavior
A clear and concise description of what you expected to happen.
The server stops

I would expect when completing /antivpn to be suggested all the existing subcommands.
Instead I get just nothing. To know the subcommands, I have to execute the main command once, just to remember the subcommands. And if that is the case, then why does command suggestion exist?

Yes, this is a copy of #21, but it got closed too early and I can't reopen it!

Version 1.7.1 displays an error when starting with a database and doesn't seem to connect to it properly, as it doesn't change anything.

It seems, that the Plugin mixes SQLite with MySql!

It creates two SqLite Databases in a Subfolder KauriVPN/databases, looking at the console output, it probably tries to connect to those and fails as it tries to use it as a MySql Database?! Both of the files can't be opend by the DB Browser (Invalid file format).

Also tested in the 1.6.1 and the Database function worked as intended without an error at startup.
