Subject: [PATCH] Untrash chat handling
|
|
|
|
Vanilla technically allows chat messages with starting slashes now,
|
|
Spigot still accepts them as commands, most likely due to being too
|
|
lazy to properly differentiate between chat and command intent in
|
|
their implementation. This disallows modified clients to send chat
|
|
messages with slashes and makes sure chat validation always happens
|
|
on the netty event loop, rather than there and possibly being moved
|
|
to the main thread, thus having the delayed handling cause a bad
|
|
process order of message ids.
