When ChunkAccess was converted to an abstract class some versions
ago, the code to initialise nibble arrays should have been moved.
However, the code was not moved and so now mods constructing their
own implementations of ChunkAccess would not have the nibble arrays
initialised.
This is ported to Paper from Starlight to keep the code base in sync,
not because it fixes anything known.
During feature generation, light data is not initialised and
will always return 15 in Starlight. Vanilla can possibly return
0 if partially initialised, which allows some mushroom blocks to
generate.
In general, the brightness value from the light engine should not
be used until the chunk is ready. To emulate Vanilla behavior better,
we return 0 as the brightness during world gen unless the target
chunk is finished lighting.
The regular light retrieval outside of WorldGenRegion remains
the same, as behaviorally chunks not lit should be at max
skylight and zero block light.
There is no point in initialising the sources in Starlight,
as we do not use them. Additionally, they are not saved to
disk so we do not need them.
Maintaining and initialising them is not a negligible cost,
which is why they are being removed.
When per-player mob spawning is enabled we do not need to randomly
shuffle the chunk list. Additionally, we can use the NearbyPlayers
class to quickly retrieve nearby players instead of possible
searching all players on the server.
We can avoid multiple ticket additions for the same ChunkTasks
instance. This will help in situations where significant number of
block updates occur for the same chunk in the same tick, such as
water draining.
Upstream has released updates that appear to apply and compile correctly.
