this fixes a potential exploit where clients could append JWTs signed with their own keys to the end of the chain containing fake XUID/UUID/username which would then overwrite the legitimate ones in earlier links.
This stems from the fact that the final link of the vanilla chain contains the client's own pubkey, so the client is able to append its own data to the end of the chain.
this implementation was god-awful bad and it was entirely avoidable to make it this complicated.
This utilizes the fact that pthreads treats static properties as thread-local. AsyncTask local storage now utilizes a \SplObjectStorage stored in an AsyncTask private static field.
this is nearly the same as 1.5.0.0, except the skin packet premium boolean has been dropped.
This isn't production ready yet because the blockID table needs updating (waiting on MrARM to fix his script for that).
This now utilizes Snooze in order to have the server wake up to process RCON commands ondemand, similar to how the CommandReader thread operates. This is better for performance and response times.
This also makes a few other changes:
- RCON thread will now waste less CPU since it uses a blocking select() with timeout to read
- Following from that, IPC sockets are used to allow interrupting select() from the RCON thread.
- Multiple threads for RCON has been removed (this is entirely unnecessary, reading data from sockets is not CPU-intensive, and a single thread is easier to work with)
This allows other threads to notify the main thread to wake it up while it's sleeping between ticks, allowing reduction of processing latency.
Currently only RakLib and the CommandReader threads utilize this, but it's planned to extend it to more things in the near future.
CommandReader is now event-driven instead of poll-based - the server will not poll the CommandReader thread for messages each tick anymore.
RakLib utilizes this mechanism to get packets processed without delays to lower latency.
This now adds an extra dependency - `pocketmine/snooze` library contains the meat of the code used for this. See the Snooze repository for details.
pthreads doesn't play well with resources, and this code upsets it. Also, this code is utterly pointless.
The whole of RCON needs burning to the ground...
