From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Spottedleaf Date: Mon, 1 Feb 2021 15:35:14 -0800 Subject: [PATCH] Fix chunks refusing to unload at low TPS The full chunk future is appended to the chunk save future, but when moving to unloaded ticket level it is not being completed with the empty chunk access, so the chunk save must wait for the full chunk future to complete. We can simply schedule to the immediate executor to get this effect, rather than the main mailbox. diff --git a/src/main/java/net/minecraft/server/level/ChunkMap.java b/src/main/java/net/minecraft/server/level/ChunkMap.java index 2d706507abc74b9fdc76958acd97dc3c6417eada..382532963a856478aa663d9b66e2169eaa36aefc 100644 --- a/src/main/java/net/minecraft/server/level/ChunkMap.java +++ b/src/main/java/net/minecraft/server/level/ChunkMap.java @@ -1272,9 +1272,7 @@ public class ChunkMap extends ChunkStorage implements ChunkHolder.PlayerProvider return chunk; }); - }, (runnable) -> { - this.mainThreadMailbox.tell(ChunkTaskPriorityQueueSorter.message(playerchunk, runnable)); - }); + }, this.mainThreadExecutor); // Paper - queue to execute immediately so this doesn't delay chunk unloading } public int getTickingGenerated() {
