this hack sends only the bare essential data to create the tiles in LevelChunkPacket,
and then separately sending the full tile data using BlockActorDataPacket afterwards.
This is necessary because the client doesn't handle items correctly in NBT when chunks are sent without using the SubChunkRequest system.
In 4.6 this is observed with incorrect items shown in item frames; in 5.0 it's seen with items simply not showing up at all (difference due to modernization of the serialization format in 5.0).
the current data management system uses case-insensitive names, so we can't allow different players with the same name in different cases to join, or we will have duplication exploits.
This typically only applies to offline servers, since Xbox Live doesn't permit reuse of a username, same case or otherwise.

- Added the following API methods:
- `Player::hasBlockCollision()`
- `Player::setHasBlockCollision()`
This enables spectator-like noclip behaviour in other gamemodes (could be useful for builders).
This reverts commit 866020dfdb06434b4f361a4a0f0faf7a89c30ed2.
For some fucking reason this broke resending chunks in some cases (and
sending chunks at all in others). I don't have time to debug this right
now, so it's going to have to remain broken, infuriatingly enough.
in the normal case, all sessions will share the same PacketSerializerContext and Compressor, so this code will be the same as before
However, for the multi-protocol hackers out there, this should reduce the maintenance burden (@Driesboy) since now only the PacketSerializerContext needs to be maintained. I recommend a separate PacketSerializerContext for each protocol (perhaps put the protocol version in the serializer context too, if you need it for some reason).
this makes translation usage much more statically analysable.
The only places this isn't used are:
- places that prefix translations with colours (those are still a problem)
- places where server/client translations don't match (e.g. gameMode.changed accepts different parameters in vanilla than in PM)
This brings a significant performance improvement to login sequence handling, reducing CPU cost of `PrepareEncryptionTask` by over 90% and `ProcessLoginTask` by over 60%. It also allows us to shed a dependency.
while this is a bit hacky outside of the protocol namespace, it makes it much easier to use the protocol library for alternative purposes, such as for a client or MITM proxy.
It also removes all but one remaining core dependency of the protocol library, making it very close to being able to be separated from the server core entirely.
phpstan doesn't report these because .. reasons .. @ondrejmirtes this is causing bugs to go unfound :(
I'm aware of the irony that I just silenced the bugs that were exposed by this commit .. that's an architectural problem for another day
despite MCPE claiming to use GCM, it omits the auth tag, which defeats the whole point of using GCM.
CTR can be used instead, with the final 4 bytes of the IV being 0002.
it's not the protocol implementation's job to decide what's garbage. It should only indicate that a packet MAY be sent by the client. It should then be up to the handler to decide what to do with it.
the commit I reverted put the preconditions in the completion handler,
which is executed AFTER THE CHUNK IS SENT.
Revert "NetworkSession: allow Player to handle its own business in chunk sending"
This reverts commit a223d1cbf3e8a9143383b6497f4d2d5d7ab3202a.
