may help #284 Cleans up the lighting queue system, reducing diff and improving implementation. We no longer stop chunk unloads due to lighting updates, and instead simply flush the lighting queue. The cost of forcing the chunk (and its neighbors!) to stay loaded waiting for its lighting work to finish is much greater than simply taking the hit and doing the work. This change also helps reduce the diff and avoid bugs with missed diffs by removing duplicated logic. Also switches to a more effecient data structure (ArrayDeque instead of LinkedList) for the queue itself.

Subject: [PATCH] Improve Maps (in item frames) performance and bug fixes
|
|
|
|
Maps used a modified version of rendering to support plugin controlled
|
|
imaging on maps. The Craft Map Renderer is much slower than Vanilla,
|
|
causing maps in item frames to cause a noticeable hit on server performance.
|
|
|
|
This updates the map system to not use the Craft system if we detect that no
|
|
custom renderers are in use, defaulting to the much simpler Vanilla system.
|
|
|
|
Additionally, numerous issues to player position tracking on maps has been fixed.
