This should greatly improve performance by using a No Op lock while on the main thread. Vanilla always had a write lock on write operations, but we added a Read Lock during Async Chunks to make concurrent writes non fatal for Async Chunks. This means we added on a bunch of over head to all chunk read operations. This corrects that, as well as disabling the write lock while on main thread. It is a general rule that you do not touch a chunk async once it is loaded into the world, as we never had locks on the chunk before 1.13 even. So once we are on main, we don't expect concurrent access to begin with, so we don't need the write locks either.

Subject: [PATCH] Fix Sending Chunks to Client
|
|
|
|
Vanilla has some screwy logic that doesn't send a chunk until
|
|
it has been post processed. This is an issue as post processing
|
|
doesn't occur until all neighbor chunks have been loaded.
|
|
|
|
This can reduce view distance while generating terrain, but also
|
|
cause bugs where chunks are never sent to the client.
|
|
|
|
This fix always sends chunks to the client, and simply updates
|
|
the client anytime post processing is triggered with the new chunk data.
