From a58127d969be71a3373e822df2131aa53a36b9c1 Mon Sep 17 00:00:00 2001 From: Zach Brown Date: Sat, 22 Sep 2018 15:56:59 -0400 Subject: [PATCH] Catch JsonParseException in Entity and TE names As a result, data that no longer parses correctly will not crash the server instead just logging the exception and continuing (and in most cases should fix the data) Player data is fixed pretty much immediately but some block data (like Shulkers) may need to be changed in order for it to re-save properly No more crashing though. diff --git a/src/main/java/net/minecraft/server/CommandBlockListenerAbstract.java b/src/main/java/net/minecraft/server/CommandBlockListenerAbstract.java index 6d85cd508e..23a69ba571 100644 --- a/src/main/java/net/minecraft/server/CommandBlockListenerAbstract.java +++ b/src/main/java/net/minecraft/server/CommandBlockListenerAbstract.java @@ -56,7 +56,7 @@ public abstract class CommandBlockListenerAbstract implements ICommandListener { this.command = nbttagcompound.getString("Command"); this.successCount = nbttagcompound.getInt("SuccessCount"); if (nbttagcompound.hasKeyOfType("CustomName", 8)) { - this.customName = IChatBaseComponent.ChatSerializer.a(nbttagcompound.getString("CustomName")); + this.customName = MCUtil.getBaseComponentFromNbt("CustomName", nbttagcompound); // Paper - Catch ParseException } if (nbttagcompound.hasKeyOfType("TrackOutput", 1)) { diff --git a/src/main/java/net/minecraft/server/Entity.java b/src/main/java/net/minecraft/server/Entity.java index f9b097fd6f..4833a9652a 100644 --- a/src/main/java/net/minecraft/server/Entity.java +++ b/src/main/java/net/minecraft/server/Entity.java @@ -1701,7 +1701,7 @@ public abstract class Entity implements INamableTileEntity, ICommandListener, Ke this.setPosition(this.locX, this.locY, this.locZ); this.setYawPitch(this.yaw, this.pitch); if (nbttagcompound.hasKeyOfType("CustomName", 8)) { - this.setCustomName(IChatBaseComponent.ChatSerializer.a(nbttagcompound.getString("CustomName"))); + this.setCustomName(MCUtil.getBaseComponentFromNbt("CustomName", nbttagcompound)); // Paper - Catch ParseException } this.setCustomNameVisible(nbttagcompound.getBoolean("CustomNameVisible")); diff --git a/src/main/java/net/minecraft/server/MCUtil.java b/src/main/java/net/minecraft/server/MCUtil.java index 6d278a0da5..ec3732193f 100644 --- a/src/main/java/net/minecraft/server/MCUtil.java +++ b/src/main/java/net/minecraft/server/MCUtil.java @@ -339,4 +339,19 @@ public final class MCUtil { return null; } } + + @Nullable + public static IChatBaseComponent getBaseComponentFromNbt(String key, NBTTagCompound compound) { + if (!compound.hasKey(key)) { + return null; + } + String string = compound.getString(key); + try { + return IChatBaseComponent.ChatSerializer.jsonToComponent(string); + } catch (com.google.gson.JsonParseException e) { + org.bukkit.Bukkit.getLogger().warning("Unable to parse " + key + " from " + compound +": " + e.getMessage()); + } + + return null; + } } diff --git a/src/main/java/net/minecraft/server/TileEntityBanner.java b/src/main/java/net/minecraft/server/TileEntityBanner.java index 560330ba05..bfc58a7754 100644 --- a/src/main/java/net/minecraft/server/TileEntityBanner.java +++ b/src/main/java/net/minecraft/server/TileEntityBanner.java @@ -57,7 +57,7 @@ public class TileEntityBanner extends TileEntity implements INamableTileEntity { public void load(NBTTagCompound nbttagcompound) { super.load(nbttagcompound); if (nbttagcompound.hasKeyOfType("CustomName", 8)) { - this.a = IChatBaseComponent.ChatSerializer.a(nbttagcompound.getString("CustomName")); + this.a = MCUtil.getBaseComponentFromNbt("CustomName", nbttagcompound); // Paper - Catch ParseException } if (this.hasWorld()) { diff --git a/src/main/java/net/minecraft/server/TileEntityContainer.java b/src/main/java/net/minecraft/server/TileEntityContainer.java index 473ec2cbde..ab6b86e4e9 100644 --- a/src/main/java/net/minecraft/server/TileEntityContainer.java +++ b/src/main/java/net/minecraft/server/TileEntityContainer.java @@ -17,7 +17,7 @@ public abstract class TileEntityContainer extends TileEntity implements IInvento super.load(nbttagcompound); this.chestLock = ChestLock.b(nbttagcompound); if (nbttagcompound.hasKeyOfType("CustomName", 8)) { - this.customName = IChatBaseComponent.ChatSerializer.a(nbttagcompound.getString("CustomName")); + this.customName = MCUtil.getBaseComponentFromNbt("CustomName", nbttagcompound); // Paper - Catch ParseException } } -- 2.22.0
