The new behavior of disconnect to block the current thread until the disconnect succeeded is better than throwing it off to happen at some point

Subject: [PATCH] Optimize nearest structure border iteration
|
|
|
|
Getting the nearest generated structure contains a nested set of loops that
|
|
iterates over all chunks at a specific chessboard distance. It does this by
|
|
iterating over the entire square of chunks within that distance, and checking
|
|
if the coordinates are at exactly the right distance to be on the border.
|
|
|
|
This patch optimizes the iteration by only iterating over the border chunks.
|
|
This evaluated chunks are the same, and in the same order, as before, to
|
|
ensure that the returned found structure (which may for example be a buried
|
|
treasure that will be marked on a treasure map) is the same as in vanilla.
