From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Thu, 8 Oct 2020 00:00:25 -0400 Subject: [PATCH] Fix "Not a string" Map Conversion spam The maps did convert successfully, but had noisy logs due to Spigot implementing this logic incorrectly. This stops the spam by converting the old format to new before requesting the world. Track spigot issue to see when fixed: https://hub.spigotmc.org/jira/browse/SPIGOT-6181 diff --git a/src/main/java/net/minecraft/world/level/saveddata/maps/MapItemSavedData.java b/src/main/java/net/minecraft/world/level/saveddata/maps/MapItemSavedData.java index 15c6f9d1c43fbedac70526a84a010be83b4cae86..2e5155fe541ed7040a6be9fdec98b23e8c45bfb0 100644 --- a/src/main/java/net/minecraft/world/level/saveddata/maps/MapItemSavedData.java +++ b/src/main/java/net/minecraft/world/level/saveddata/maps/MapItemSavedData.java @@ -14,6 +14,8 @@ import net.minecraft.core.BlockPos; import net.minecraft.nbt.CompoundTag; import net.minecraft.nbt.ListTag; import net.minecraft.nbt.NbtOps; +import net.minecraft.nbt.NumericTag; +import net.minecraft.nbt.StringTag; import net.minecraft.nbt.Tag; import net.minecraft.network.chat.Component; import net.minecraft.network.protocol.Packet; @@ -104,7 +106,26 @@ public class MapItemSavedData extends SavedData { } public static MapItemSavedData load(CompoundTag nbt) { - DataResult dataresult = DimensionType.parseLegacy(new Dynamic(NbtOps.INSTANCE, nbt.get("dimension"))); + // Paper start - fix "Not a string" spam + Tag dimension = nbt.get("dimension"); + if (dimension instanceof NumericTag && ((NumericTag) dimension).getAsInt() >= CraftWorld.CUSTOM_DIMENSION_OFFSET) { + long least = nbt.getLong("UUIDLeast"); + long most = nbt.getLong("UUIDMost"); + + if (least != 0L && most != 0L) { + UUID uuid = new UUID(most, least); + CraftWorld world = (CraftWorld) Bukkit.getWorld(uuid); + if (world != null) { + dimension = StringTag.valueOf("minecraft:" + world.getName().toLowerCase(java.util.Locale.ENGLISH)); + } else { + dimension = StringTag.valueOf("bukkit:_invalidworld_"); + } + } else { + dimension = StringTag.valueOf("bukkit:_invalidworld_"); + } + } + DataResult> dataresult = DimensionType.parseLegacy(new Dynamic(NbtOps.INSTANCE, dimension)); // CraftBukkit - decompile error + // Paper end - fix "Not a string" spam Logger logger = MapItemSavedData.LOGGER; Objects.requireNonNull(logger);
