* Remove usages of net.minecraft and craftbukkit
* Restore packet type backward compatibility (tested on 1.8)
* Re-add last removed packets
* Fix sub class naming for newer minecraft versions
To note: this is yet another compatibility change for my Geyser work, but https://github.com/PaperMC/Paper/pull/5611 will also break without these changes as Unix domain sockets don't implement SocketChannel.
The temporary player method delegation directed the isOnline and getName methods to functions that require the channel to be an instance of SocketChannel, when this won't always be the case. To solve this, this PR redirects `getSocket().getRemoteSocketAddress()` to `injector.getAddress()` which returns the same value. To determine if the player is online, a new method is created in SocketInjector to determine if a connection is online (which also returns the same value as before this commit).
- Updated ByteBuddy dependency to add support for Java 17 (introduced in 1.10.21) and to take advantage of any fixes and improvements made between versions.
Fixes#1170.
The reasoning for this PR is largely outlined in the above issue. As the ChannelInboundHandlerAdapter has no private class, a race condition cannot occur and therefore marking the class as sharable should incur no cost.
In previous Minecraft versions, using WrappedServerPing.setMotD(String)
behaved exactly like using Bukkit's ServerListPingEvent.setMotd(String).
With the addition of RGB colors in Minecraft 1.16, Spigot's
ServerListPingEvent was patched to translate the MotD string to the
chat component equivalent to make it possible to use RGB colors in MotDs.
In general, using raw legacy color codes (e.g. §c) within a (JSON) text
component tends to cause weird issues on newer Minecraft versions,
so it's better to translate them to the JSON equivalents on the server.
However, the WrappedServerPing implementation in ProtocolLib was never
updated with the same change, which makes it behave differently from
Spigot's ServerListPingEvent now. Using ServerListPingEvent RGB color
codes work, using ProtocolLib they do not work.
To fix this, this commit changes WrappedServerPing.setMotD(String) to
use the same method as Spigot for translating the legacy text to the
JSON/chat component equivalent.
This allows for example ServerListPlus to use Spigot's RGB color codes
(e.g. &x&7&9&b&8&f&fHello) without requiring any changes in ServerListPlus.
Switched from the now-unavailable ClassLoader::defineClass method to the java.lang.invoke.MethodHandles.Lookup::defineClass. This is available on Java 9+.
- The gclib dependency in the EnchancerFactory has been removed. All classes that used the actual factory part of it have been updated to use bytebuddy instead. This class will have to be removed at some point, but at the moment it is still used for accessing its class loader.
- Renamed EnhancerFactory to ByteBuddyFactory. All ByteBuddy actions should go through this now. Every subclass created here implements the ByteBuddyGenerated interface. This makes it possible to recognize classes generated using ByteBuddy (by default, it doesn't leave such a trace).
- Removed the method DefaultInstances#forEnhancer(Enhancer). This method isn't used anywhere; the last trace of usage of the method I could find was in 2013 (in the NetworkServerInjector). External plugins (I couldn't find any that used it), they should really have their own implementation, given that they already require an instance of an Enchancer. As such, I feel it is safe to remove rather than update it.
