Andrew Steinborn 75ddeb062f Confine preconnect validation/setup logic to event loop. 2020-05-25 09:38:22 -04:00

Andrew Steinborn 793e938dd1 Drop macOS native support 
This served a good purpose when I used macOS as a primary development system, but those days are gone (I use Linux now). The spirit of multiple variants is preserved by our special Java 11+ optimized compression.

Andrew Steinborn b3bd773fea Switch out Cloudflare zlib for libdeflate. 
libdeflate is significantly faster than vanilla zlib, zlib-ng, and Cloudflare zlib. It is also MIT-licensed (so no licensing concerns). In addition, it simplifies a lot of the native code (something that's been tricky to get right).

While we're at it, I have also taken the time to fine-time compression in Velocity in general. Thanks to this work, native compression only requires one JNI call, an improvement from the more than 2 (sometimes up to 5) that were possible before. This optimization also extends to the existing Java compressors, though they require potentially two JNI calls.

Andrew Steinborn 91e9769c5a Cap /server list to 50 servers. 
Any more, and the server list is arguably useless. Thanks to BXBW for finding this particular issue!

Andrew Steinborn 81a0cbe3b9 Fix rare race condition with transitioning 
If the player unexpectedly disconnects after ServerConnectEvent is
fired, but before the connection transitions to the new player, Velocity
would throw an exception thinking the connection was not present. This
is the correct behavior, but the behavior is very surprising. Instead we
will double-check to ensure the connection has not been lost before we
continue with transitioning to the new server.

I am making this change to make the login process less "chatty" for
higher-latency links and 1.13+ servers.
