From b0972764eddda27e7f6ff9e0f55f2fecda2bb046 Mon Sep 17 00:00:00 2001 From: Aikar Date: Wed, 21 Mar 2018 19:57:10 -0400 Subject: [PATCH] Configurable Unrestricted Signs Bukkit restricts command execution of signs to test if the sender has permission to run the specified command. This breaks vanilla maps that use signs to intentionally run as elevated permission. Bukkit provides an unrestricted advancements setting, so this setting compliments that one and allows for unrestricted signs. We still filter sign update packets to strip out commands at edit phase, however there is no sanity in ever expecting creative mode to not be able to create signs with any command. Creative servers should absolutely never enable this. Non creative servers, enable at own risk!!! diff --git a/src/main/java/net/minecraft/server/TileEntitySign.java b/src/main/java/net/minecraft/server/TileEntitySign.java index 3f2c5b2d..67bd3bcb 100644 --- a/src/main/java/net/minecraft/server/TileEntitySign.java +++ b/src/main/java/net/minecraft/server/TileEntitySign.java @@ -38,7 +38,7 @@ public class TileEntitySign extends TileEntity { public void load(NBTTagCompound nbttagcompound) { this.isEditable = false; super.load(nbttagcompound); - ICommandListener icommandlistener = new ICommandListener() { + ICommandListener icommandlistener = new ISignCommandListener() { // Paper public String getName() { return "Sign"; } @@ -125,7 +125,7 @@ public class TileEntitySign extends TileEntity { } public boolean b(final EntityHuman entityhuman) { - ICommandListener icommandlistener = new ICommandListener() { + ICommandListener icommandlistener = new ISignCommandListener() { // Paper public String getName() { return entityhuman.getName(); } @@ -200,4 +200,5 @@ public class TileEntitySign extends TileEntity { public CommandObjectiveExecutor f() { return this.i; } + public interface ISignCommandListener extends ICommandListener {} // Paper } diff --git a/src/main/java/org/bukkit/craftbukkit/CraftServer.java b/src/main/java/org/bukkit/craftbukkit/CraftServer.java index e86c1675..6095948e 100644 --- a/src/main/java/org/bukkit/craftbukkit/CraftServer.java +++ b/src/main/java/org/bukkit/craftbukkit/CraftServer.java @@ -175,6 +175,7 @@ public final class CraftServer implements Server { private CraftIconCache icon; private boolean overrideAllCommandBlockCommands = false; private boolean unrestrictedAdvancements; + private boolean unrestrictedSignCommands; // Paper private final List playerView; public int reloadCount; public static Exception excessiveVelEx; // Paper - Velocity warnings @@ -253,6 +254,12 @@ public final class CraftServer implements Server { saveCommandsConfig(); overrideAllCommandBlockCommands = commandsConfiguration.getStringList("command-block-overrides").contains("*"); unrestrictedAdvancements = commandsConfiguration.getBoolean("unrestricted-advancements"); + // Paper start + unrestrictedSignCommands = commandsConfiguration.getBoolean("unrestricted-signs"); + if (unrestrictedSignCommands) { + logger.warning("Warning: Commands are no longer restricted on signs.
