From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Sat, 11 Apr 2020 03:56:07 -0400 Subject: [PATCH] Implement Chunk Priority / Urgency System for Chunks Mark chunks that are blocking main thread for world generation as urgent Implements a general priority system so that chunks that are sorted in the generator queues can prioritize certain chunks over another. Urgent chunks will jump to the front of the line, ensuring that a sync chunk load on an ungenerated chunk does not lag the server for a long period of time if the servers generator queues are filled with lots of chunks already. This massively reduces the lag spikes from sync chunk gens. Then we further prioritize loading order so nearby chunks have higher priority than distant chunks, reducing the pressure a high no tick view distance holds on you. Chunks in front of the player have higher priority, to help with fast traveling players keep up with their movement. diff --git a/src/main/java/com/destroystokyo/paper/io/chunk/ChunkTaskManager.java b/src/main/java/com/destroystokyo/paper/io/chunk/ChunkTaskManager.java index 49a594e5f345096cb3b9913b8ee2760795c5f012..bcb7ce2692c5bc1a6214c3a384949666107864fb 100644 --- a/src/main/java/com/destroystokyo/paper/io/chunk/ChunkTaskManager.java +++ b/src/main/java/com/destroystokyo/paper/io/chunk/ChunkTaskManager.java @@ -4,7 +4,10 @@ import com.destroystokyo.paper.io.PaperFileIOThread; import com.destroystokyo.paper.io.IOUtil; import com.destroystokyo.paper.io.PrioritizedTaskQueue; import com.destroystokyo.paper.io.QueueExecutorThread; +import it.unimi.dsi.fastutil.longs.Long2ObjectMap; +import net.minecraft.server.ChunkCoordIntPair; import net.minecraft.server.ChunkRegionLoader; +import net.minecraft.server.ChunkStatus; import net.minecraft.server.IAsyncTaskHandler; import net.minecraft.server.IChunkAccess; import net.minecraft.server.MinecraftServer; @@ -106,7 +109,7 @@ public final class ChunkTaskManager { } static void dumpChunkInfo(Set seenChunks, PlayerChunk chunkHolder, int x, int z) { - dumpChunkInfo(seenChunks, chunkHolder, x, z, 0, 1); + dumpChunkInfo(seenChunks, chunkHolder, x, z, 0, 4); } static void dumpChunkInfo(Set seenChunks, PlayerChunk chunkHolder, int x, int z, int indent, int maxDepth) { @@ -127,6 +130,30 @@ public final class ChunkTaskManager { PaperFileIOThread.LOGGER.log(Level.ERROR, indentStr + "Chunk Status - " + ((chunk == null) ?
