Subject: [PATCH] Ensure commands are not ran async
|
|
|
|
Plugins calling Player.chat("/foo") or Server.dispatchCommand() could
|
|
trigger the server to execute a command while on another thread.
|
|
|
|
These commands would then process EXPECTING to be on the main thread, leaving to
|
|
very hard to trace concurrency issues.
|
|
|
|
This change will synchronize the command execution back to the main thread, causing a
|
|
big slowdown in execution but throwing an exception at same time to raise awareness
|
|
that it is happening so that plugin authors can fix their code to stop executing commands async.
|
|
|
|
This also properly splits up the chat and command handling to reflect the server now
|
|
having separate packets for both, and the client always using the correct packet. Text
|
|
from a chat packet should never be parsed into a command, even if it starts with the `/`
|
|
character.
