From 5c7269fbecfab55d9d9aaae09ccd13df67fad70b Mon Sep 17 00:00:00 2001 From: Aikar Date: Fri, 28 Sep 2018 22:27:33 -0400 Subject: [PATCH] Don't recheck type after setting a block The server does a "Did my update succeed" check after setting a blocks data to a chunk. However, writes can not fail outside of a hard error or a a race condition from multiple threads writing, which is not something that should ever occur on the server. So this check is pointless, as if it did occur, the server would be having data corruption issues anyways. This provides a small boost to all setType calls. diff --git a/src/main/java/net/minecraft/server/Chunk.java b/src/main/java/net/minecraft/server/Chunk.java index 966879a894..0d51c1baeb 100644 --- a/src/main/java/net/minecraft/server/Chunk.java +++ b/src/main/java/net/minecraft/server/Chunk.java @@ -558,7 +558,7 @@ public class Chunk implements IChunkAccess { this.world.n(blockposition); } - if (chunksection.getType(i, j & 15, k).getBlock() != block) { + if (false && chunksection.getType(i, j & 15, k).getBlock() != block) { // Paper - don't need to recheck this - this would only fail due to non main thread writes which are not supported return null; } else { if (flag1) { -- 2.21.0
