From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Callahan Date: Wed, 8 Apr 2020 02:42:14 -0500 Subject: [PATCH] Async command map building This adds a custom pool inorder to make sure that they are closed without much though, as it doesn't matter if the client is not sent commands if the server is restarting. Using the default async pool caused issues to arise due to the shutdown logic generally being much later. diff --git a/src/main/java/net/minecraft/commands/Commands.java b/src/main/java/net/minecraft/commands/Commands.java index 9eaa7ad424252ea2e033d6041a14bf1ef7dd9fde..6e931aa7220180336b64fbb3b4090df278fca0fa 100644 --- a/src/main/java/net/minecraft/commands/Commands.java +++ b/src/main/java/net/minecraft/commands/Commands.java @@ -368,6 +368,24 @@ public class Commands { if ( org.spigotmc.SpigotConfig.tabComplete < 0 ) return; // Spigot // CraftBukkit start // Register Vanilla commands into builtRoot as before + // Paper start - Async command map building + COMMAND_SENDING_POOL.execute(() -> { + this.sendAsync(player); + }); + } + + public static final java.util.concurrent.ThreadPoolExecutor COMMAND_SENDING_POOL = new java.util.concurrent.ThreadPoolExecutor( + 0, 2, 60L, java.util.concurrent.TimeUnit.SECONDS, + new java.util.concurrent.LinkedBlockingQueue<>(), + new com.google.common.util.concurrent.ThreadFactoryBuilder() + .setNameFormat("Paper Async Command Builder Thread Pool - %1$d") + .setUncaughtExceptionHandler(new net.minecraft.DefaultUncaughtExceptionHandlerWithName(net.minecraft.server.MinecraftServer.LOGGER)) + .build(), + new java.util.concurrent.ThreadPoolExecutor.DiscardPolicy() + ); + + private void sendAsync(ServerPlayer player) { + // Paper end - Async command map building Map, CommandNode> map = Maps.newIdentityHashMap(); // Use identity to prevent aliasing issues RootCommandNode vanillaRoot = new RootCommandNode(); @@ -385,7 +403,14 @@ public class Commands { for (CommandNode node : rootcommandnode.getChildren()) { bukkit.add(node.getName()); } + // Paper start - Async command map building + net.minecraft.server.MinecraftServer.getServer().execute(() -> { + runSync(player, bukkit, rootcommandnode); + }); + } + private void runSync(ServerPlayer player, Collection bukkit, RootCommandNode rootcommandnode) { + // Paper end - Async command map building PlayerCommandSendEvent event = new PlayerCommandSendEvent(player.getBukkitEntity(), new LinkedHashSet<>(bukkit)); event.getPlayer().getServer().getPluginManager().callEvent(event); diff --git a/src/main/java/net/minecraft/server/MinecraftServer.java b/src/main/java/net/minecraft/server/MinecraftServer.java index f9007905422f7a6eac7c78fd5bdb17cb4da96712..1685f92acdf63decc6cd6b37957ca61212b43bbc 100644 --- a/src/main/java/net/minecraft/server/MinecraftServer.java +++ b/src/main/java/net/minecraft/server/MinecraftServer.java @@ -897,6 +897,7 @@ public abstract class MinecraftServer extends ReentrantBlockableEventLoop
