Subject: [PATCH] Fix and optimise world force upgrading
|
|
|
|
The WorldUpgrader class was incorrectly modified by
|
|
CB. It will store an IChunkLoader instance for all
|
|
dimension types in the world, but obviously with how
|
|
CB shifts around worlds only one dimension type exists
|
|
per world. But this would be OK if CB did this
|
|
change correctly. All IChunkLoader instances
|
|
will point to the same regionfiles. And all
|
|
IChunkLoader instances are going to be read from.
|
|
|
|
This problem hasn't really been reported because
|
|
it relies on the persistent legacy data to be converted
|
|
as well to cause corruption. Why? Because the legacy
|
|
data is also shared, it will result in different
|
|
outputs from conversion (as once conversion for legacy
|
|
persistent data takes place, it is REMOVED - so the next
|
|
convert will _not_ have the data). Which means different
|
|
sizes on disk. Which means different regionfile sector
|
|
allocations. Which means there are 3 different possible
|
|
regionfile sector allocations in memory, and none of them
|
|
are going to be correct.
|
|
|
|
I've fixed this by writing a world upgrader suited to
|
|
CB's changes to world folder format. It was brain dead
|
|
easy to add threading, so I did.
