* Updated Upstream (Bukkit/CraftBukkit) Upstream has released updates that appears to apply and compile correctly. This update has not been tested by PaperMC and as with ANY update, please do your own testing Bukkit Changes: 45690fe9 SPIGOT-5047: Correct slot types for 1.14 inventories CraftBukkit Changes:4090d01fSPIGOT-5047: Correct slot types for 1.14 inventoriese8c08362SPIGOT-5046: World#getLoadedChunks returning inaccessible cached chunks.d445af3bSPIGOT-5067: Add item meta for 1.14 spawn eggs * Bring Chunk load checks in-line with spigot As of the last upstream merge spigot now checks ticket level status when returning loaded chunks for a world from api. Now our checks will respect that decision. * Fix spawn ticket levels Vanilla would keep the inner chunks of spawn available for ticking, however my changes made all chunks non-ticking. Resolve by changing ticket levels for spawn chunks inside the border to respect this behavior. * Make World#getChunkIfLoadedImmediately return only entity ticking chunks Mojang appears to be using chunks with level > 33 (non-ticking chunks) as cached chunks and not actually loaded chunks. * Bring all loaded checks in line with spigot Loaded chunks must be at least border chunks, or level <= 33

Subject: [PATCH] Use Optimized Collections
|
|
|
|
Swap out CraftBukkit LongObjectHashMap with Long2ObjectOpenHashMap
|
|
Swap out Integer key HashMap for a Int2ObjectOpenHashMap For ChunkProviderServer
|
|
|
|
Amaranth, the creator of LongObjectHashMap, tested it vs fastutil and determined fastutil to be 3x faster
|
|
and could not create anything faster than fastutil.
|
|
|
|
These collections are super fast as seen
