Patch documentation to come Issues with the old system that are fixed now: - World generation does not scale with cpu cores effectively. - Relies on the main thread for scheduling and maintaining chunk state, dropping chunk load/generate rates at lower tps. - Unreliable prioritisation of chunk gen/load calls that block the main thread. - Shutdown logic is utterly unreliable, as it has to wait for all chunks to unload - is it guaranteed that the chunk system is in a state on shutdown that it can reliably do this? Watchdog shutdown also typically failed due to thread checks, which is now resolved. - Saving of data is not unified (i.e can save chunk data without saving entity data, poses problems for desync if shutdown is really abnormal. - Entities are not loaded with chunks. This caused quite a bit of headache for Chunk#getEntities API, but now the new chunk system loads entities with chunks so that they are ready whenever the chunk loads in. Effectively brings the behavior back to 1.16 era, but still storing entities in their own separate regionfiles. The above list is not complete. The patch documentation will complete it. New chunk system hard relies on starlight and dataconverter, and most importantly the new concurrent utilities in ConcurrentUtil. Some of the old async chunk i/o interface (i.e the old file io thread reroutes _some_ calls to the new file io thread) is kept for plugin compat reasons. It will be removed in the next major version of minecraft. The old legacy chunk system patches have been moved to the removed folder in case we need them again.

Subject: [PATCH] Optimise general POI access
|
|
|
|
There are a couple of problems with mojang's POI code.
|
|
Firstly, it's all streams. Unsurprisingly, stacking
|
|
streams on top of each other is horrible for performance
|
|
and ultimately took up half of a villager's tick!
|
|
|
|
Secondly, sometime's the search radius is large and there are
|
|
a significant number of poi entries per chunk section. Even
|
|
removing streams at this point doesn't help much. The only solution
|
|
is to start at the search point and iterate outwards. This
|
|
type of approach shows massive gains for portals, simply because
|
|
we can avoid sync loading a large area of chunks. I also tested
|
|
a massive farm I found in JellySquid's discord, which showed
|
|
to benefit significantly simply because the farm had so many
|
|
portal blocks that searching through them all was very slow.
|
|
|
|
Great care has been taken so that behavior remains identical to
|
|
vanilla, however I cannot account for oddball Stream API
|
|
implementations, if they even exist (streams can technically
|
|
be loose with iteration order in a sorted stream given its
|
|
source stream is not tagged with ordered, and mojang does not
|
|
tag the source stream as ordered). However in my testing on openjdk
|
|
there showed no difference, as expected.
|
|
|
|
This patch also specifically optimises other areas of code to
|
|
use PoiAccess. For example, some villager AI and portaling code
|
|
had to be specifically modified.
