Subject: [PATCH] Break up and make tab spam limits configurable
|
|
|
|
Due to the changes in 1.13, clients will send a tab completion request
|
|
for all bukkit commands in order to factor in the lack of support for
|
|
brigadier and provide backwards support in the API.
|
|
|
|
Craftbukkit, however; has moved the chat spam limiter to also interact
|
|
with the tab completion request, which while good for avoiding abuse,
|
|
causes 1.13 clients to easilly be kicked from a server in bukkit due
|
|
to this. Removing the spam limit could cause issues for servers, however,
|
|
there is no way for servers to manipulate this without blindly cancelling
|
|
kick events, which only causes additional complications. This also causes
|
|
issues in that the tab spam limit and chat share the same field but different
|
|
limits, meaning that a player having typed a long command may be kicked from
|
|
the server.
|
|
|
|
Splitting the field up and making it configurable allows for server owners
|
|
to take the burden of this into their own hand without having to rely on
|
|
plugins doing unsafe things.
