Pasqual Koschmieder 4f18d37832 fix exceptions when reloading the server (#1689) 2022-06-29 19:08:14 -04:00
Photon-GitHubandDan Mulloy a2bf242097 Cleanup (#1603)
* Replace guava Charsets with StandardCharsets.

* Use try-with-resources

* Faster Util asList, inline getOnlinePlayers.

* Use direct ArrayList allocation.

* Use new instead of Lists#...

* Use new instead of Lists#...

* Faster looping.

* Use switch.

* Remove diamond operators.

* Use ArrayDeque instead of LinkedList.

* Actually conform to the documentation and always use an ArrayList as backing list.

* Potentially breaking change: Use switch instead of startsWith as this e.g. causes "n" to be interpreted as "names" and any future new commands starting with "n" will be ignored.

* Use addAll().

* Remove IntegerSet. Unused and also covered by fastutils IntSet.

* Much faster boolean parsing. Might have breaking changes as parameterName is now checked after the false block.

* Make most fields final, fix JavaDoc and remove diamond operators.

* Make fields final.

* Much cleaner getAllInterfaces() method.

Rothes dbedab0c14 Check entityID whether is negative or not. (#1362) 2021-09-22 10:51:47 -04:00
Pim van der Loos 5dda8c8ab1 Fix entity tracker methods for 1.17 (#1354)
- In 1.17, EntityTrackerEntries use ServerPlayerConnections instead of EntityPlayers as they did before. This caused the updateEntity to silently fail when removing the players from the trackedPlayers collection (of connections). This was resolved by retrieving the connections of the players before removing them from the list on 1.17+.
The getEntityTrackers method failed because it could not find any players for the same reason. This was resolved by retrieving the player from the connection before retrieving the Bukkit player from the EntityPlayer object when running on 1.17+.
- This fixes dmulloy2/ProtocolLib#1340

Camotoy 6f91bd23de Remove inferences of SocketChannel presence in temporary player (#1188)
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).

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.

Minecrell b3ccf82597 WrappedServerPing: Properly translate MotD to components for RGB colors (#1152)
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

PimvanderLoos b54dd49426 Replace CGLib with ByteBuddy (#984)
- 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.

Thibaut Gautier 2b22999b94 Fixed "protocollib_encoder" attempting to read non-nms packets (#959)
Added an override to the encoder as such would process any non-wire packets as NMS packets. In the case of the use of different APIs, such as Artemis Packet API, such would cause a conflict and would spit out casting exceptions. It is quite easy to resolve by exclusively accepting Wire Packets and packets which are assignable to the packet class. This solves the issue and tada happy ending.

PimvanderLoosandMark Vainomaa bbb053aa4e Fix Java 15 (#1025)
- Implemented a fix for the incompatibility with Java 15. This incompatibility was caused by the fact that the lambda generated in the NMS.NetworkManager is a hidden class in J15. Starting in Java 15, final fields in hidden classes can no longer be modified regardless of the 'accessible' flag. (see https://openjdk.java.net/jeps/371 "Using a hidden class", point 3). To circumvent this issue, this retrieves the data from the existing fields in the hidden class (a runnable or a callable) other than the packet. It then retrieves the constructor of the hidden class and instantiates it using the previously-retrieved data and the modified packet instance (this code is only used if the packet instance changed).
- Introduced a new ObjectReconstructor class that does all the fields/constructor discovering/accessing etc. The Runnable and Callable methods each get one instance of this class so that we can avoid having to get the fields/constructors and set them accessible every time we want to replace a packet.

Fix NPE when writing PlayerInfoData to packet
2015-01-08 20:10:31 -05:00
Mark Hendriks dd5bfd5f16 Fix NPE when writing PlayerInfoData to packet
By default, the listName field in EntityPlayer is null. As the WrappedChatComponent ignores null values (which in itself is completely fine), the field will be null when you read one while the EntityPlayer has no listName. When you try to write one, however, the converter directly accesses the handle from the WrappedChatComponent. This means you will be trying to access the handle of null when you don't explicitly set the displayName in such a packet.

Contributing to ProtocolLib
===========================
This page will detail specific things that must be done if you intend to contribute to this project.
## Updating ProtocolLib to a New Protocol Version
#### Before we get started:
1. **When do we need to update the protocol version?**
_A Minecraft protocol version is a number for each specification of the Minecraft protocol.
This means it is incremented when there is a change to the [Protocol Specification](http://wiki.vg/Protocol),
but not necessarily for each Minecraft version update. If the latest Minecraft version contains a protocol change,
that means ProtocolLib needs to be updated._
2. **When do we need to update other parts of ProtocolLib?**
_When the package version guard changes. The package version guard is the version string inserted
into the package identifier for CraftBukkit and net.minecraft.server (e.g. v1_9_R2). It is incremented
by Spigot if there is a major breaking change in the internal server code. This is to encourage plugins
that interact directly with CraftBukkit/nms code to update more specifically. However, since most of
ProtocolLib uses reflection, and the structure of packet classes is generally static, one will have
to go through the code and change imports from nms/CraftBukkit._
#### Ready? Let's get started!
1. Read the [Protocol Changes](http://wiki.vg/Protocol_History). Always make sure the list is both
complete and correct. If you're unsure, don't hesitate to ask in #mcdevs (the people who maintain wiki.vg) on [libera.chat](http://libera.chat)
or #spigot on [irc.spi.gt](http://irc.spi.gt) ([webchat](https://irc.spi.gt/iris/?channels=spigot)).
2. Search for usages of the now-defunct NMS package guard and change them.
3. The class `com.comphenix.protocol.PacketType` contains a list of all the packets. If any packets were added or removed
(or had their ID changed), make sure to update this list. If a packet was removed
in favor of usage of another packet, instead of removing it, move it to the bottom of the list
in its section, add a deprecation warning to it, and redirect it to the packet that replaced it.
4. `mvn` in the root directory to build the project.
5. If tests fail in the maven build, go through the tests to make sure you removed references to any removed packets
and changed the NMS version guards.
6. Increment the package version in `com.comphenix.protocol.utility.Constants`.
7. `com.comphenix.protocol.ProtocolLibrary` contains several constants that must be updated, including the Minecraft version
and the release date.
8. `com.comphenix.protocol.utility.MinecraftProtocolVersion` contains a map of all the protocol version integers.
If the protocol version has been incremented, add a new line to the map.
9. `mvn` in root directory again. If it builds successfully, test on the appropriate version of a Spigot server. If
the build fails, debug!
