Subject: [PATCH] handle PacketPlayInKeepAlive async and revert keepalive limit
|
|
|
|
In 1.12.2, Mojang moved the processing of PacketPlayInKeepAlive off the main
|
|
thread, while entirely correct for the server, this causes issues with
|
|
plugins which are expecting the PlayerQuitEvent on the main thread.
|
|
|
|
In order to counteract some bad behavior, we will post handling of the
|
|
disconnection to the main thread, but leave the actual processing of the packet
|
|
off the main thread.
|
|
|
|
We also revert the bump on the servers built in keepalive back to 15 seconds,
|
|
this solves a read timeout in scenarios where the client isn't sending data to
|
|
the server, e.g. spectating an entity.
