From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Shane Freeder Date: Sat, 19 Mar 2022 12:12:22 +0000 Subject: [PATCH] Buffer OOB setBlock calls lets debug mode throw a trace in order to potentially see where such calls are cascading from easier, but, generally, if you see one setBlock call, you're gonna see more, and this just potentially causes a flood of logs which can cause issues for slower terminals, etc. We can limit the flood by just allowing one for a single gen region, we'll also only gen a trace for the first one, I see no real pressing need to generate more, given that that would *massively* negate this patch otherwise diff --git a/src/main/java/net/minecraft/server/level/WorldGenRegion.java b/src/main/java/net/minecraft/server/level/WorldGenRegion.java index 3f5ba2b2f01d8cc07c4200a60b1b08cb584b170e..49c7825156afd053df1b7721a63070b51427aff2 100644 --- a/src/main/java/net/minecraft/server/level/WorldGenRegion.java +++ b/src/main/java/net/minecraft/server/level/WorldGenRegion.java @@ -296,6 +296,7 @@ public class WorldGenRegion implements WorldGenLevel { } } + private boolean hasSetFarWarned = false; // Paper @Override public boolean ensureCanWrite(BlockPos pos) { int i = SectionPos.blockToSectionCoord(pos.getX()); @@ -315,7 +316,15 @@ public class WorldGenRegion implements WorldGenLevel { return true; } else { + // Paper start + if (!hasSetFarWarned) { Util.logAndPauseIfInIde("Detected setBlock in a far chunk [" + i + ", " + j + "], pos: " + pos + ", status: " + this.generatingStatus + (this.currentlyGenerating == null ?
