Upstream has released updates that appears to apply and compile correctly.
This update has not been tested by PaperMC and as with ANY update, please do your own testing
My recent work on serialization is now in CraftBukkit so was able to drop the patch and Paper
is now consistent with upstream.

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.
