From b109748c82366091cedff693b08fc989943af53f Mon Sep 17 00:00:00 2001 From: Zach Brown Date: Tue, 17 Apr 2018 21:26:31 -0400 Subject: [PATCH] Handle bad chunks more gracefully Prior to this change the server would crash when attempting to load a chunk from a region with bad data. After this change the server will defer back to vanilla behavior. At this time, that means attempting to generate a chunk in its place (and occasionally just not generating anything and leaving small holes in the world). Should Mojang choose to alter this behavior in the future, this change will simply defer to whatever that new behavior is. diff --git a/src/main/java/net/minecraft/server/ChunkProviderServer.java b/src/main/java/net/minecraft/server/ChunkProviderServer.java index de859ffd1..55dada668 100644 --- a/src/main/java/net/minecraft/server/ChunkProviderServer.java +++ b/src/main/java/net/minecraft/server/ChunkProviderServer.java @@ -162,6 +162,13 @@ public class ChunkProviderServer implements IChunkProvider { return null; } else { chunk = ChunkIOExecutor.syncChunkLoad(world, loader, this, i, j); + + // Paper start - If there was an issue loading the chunk from region, stage1 will fail and stage2 will load it sync + // all we need to do is fetch an instance + if (chunk == null) { + chunk = getChunkIfLoaded(i, j); + } + // Paper end } } else if (chunk == null && generate) { chunk = originalGetChunkAt(i, j); diff --git a/src/main/java/org/bukkit/craftbukkit/chunkio/ChunkIOProvider.java b/src/main/java/org/bukkit/craftbukkit/chunkio/ChunkIOProvider.java index ef9529add..cdf3b614c 100644 --- a/src/main/java/org/bukkit/craftbukkit/chunkio/ChunkIOProvider.java +++ b/src/main/java/org/bukkit/craftbukkit/chunkio/ChunkIOProvider.java @@ -30,6 +30,11 @@ class ChunkIOProvider implements AsynchronousExecutor.CallBackProvider
