This patch does not appear to be doing anything useful, and may hide errors. Currently, the save logic does not run through this path either so it did not do anything. Additionally, properly implement support for handling RegionFileSizeException in Moonrise.

Subject: [PATCH] Make sure inlined getChunkAt has inlined logic for loaded
|
|
chunks
|
|
|
|
Tux did some profiling some time ago and showed that the
|
|
previous getChunkAt method which had inlined logic for loaded
|
|
chunks did get inlined, but the standard CPS.getChunkAt
|
|
method was not inlined.
