Andrew Steinborn 37a4199d43 Combine VarInt prefix encoding with compression 
This saves us a memory copy in the common "there is no need to compress this packet" case.

Andrew Steinborn 1cef82d54d Unroll the VarInt writing loop 
This is about as optimized as it can get. Thanks to @Leymooo for the idea, I simply expanded on it. We optimize for the common 1-3 byte cases, and punt more "complicated" cases to the original VarInt writing function we had before.

Andrew Steinborn 3dc8e25ec7 Fix varint writing (for real!) 
Thanks to @Leymooo for reporting and providing test cases. (I also added one of my own tests which proved the most useful to debugging the issue.)

Andrew Steinborn 4ca97a6df9 Reapply "Optimize varint writing" 
Inspired by the approach described at the bottom of https://richardstartin.github.io/posts/dont-use-protobuf-for-telemetry

Given that we do a lot of varint writing as well, this should provide a small performance boost for larger/complex packets whilst not regressing hard on smaller packets.

This includes a test to ensure that the behavior is as expected and fixes the initialization loop so that the correct results will be given. Much thanks to @octylFractal for acting as my duck while trying to figure this out.

Andrew Steinborn f1cb3eb1a2 Move timeout handler to after frame decoder 
Mitigates attacks like the one described in SpigotMC/BungeeCord#3066. This cannot be considered a full protection, only a mitigation that expects full packets. The attack described is essentially the infamous Slowloris attack.
 2021-04-15 22:56:37 -04:00

Also fixed another small nit.

This reverts commit 4f80d2b261.

Experience elsewhere (Waterfall PR) and confirmation from TCPShield means
this ought to work. Let's hope.
