From 3cb0b6d7c63707cbd9f2b2c7c043f82fc5eda9e6 Mon Sep 17 00:00:00 2001 From: Aikar Date: Mon, 16 May 2016 20:47:41 -0400 Subject: [PATCH] Optimize UserCache / Thread Safe Because Techable keeps complaining about how this isn't thread safe, easier to do this than replace the entire thing. Additionally, move Saving of the User cache to be done async, incase the user never changed the default setting for Spigot's save on stop only. diff --git a/src/main/java/net/minecraft/server/MinecraftServer.java b/src/main/java/net/minecraft/server/MinecraftServer.java index 9455475..a4f7e4d 100644 --- a/src/main/java/net/minecraft/server/MinecraftServer.java +++ b/src/main/java/net/minecraft/server/MinecraftServer.java @@ -508,7 +508,7 @@ public abstract class MinecraftServer implements Runnable, ICommandListener, IAs // Spigot start if (org.spigotmc.SpigotConfig.saveUserCacheOnStopOnly) { LOGGER.info("Saving usercache.json"); - this.X.c(); + this.X.c(false); // Paper } // Spigot end } diff --git a/src/main/java/net/minecraft/server/UserCache.java b/src/main/java/net/minecraft/server/UserCache.java index ccfc755..989758c 100644 --- a/src/main/java/net/minecraft/server/UserCache.java +++ b/src/main/java/net/minecraft/server/UserCache.java @@ -108,7 +108,7 @@ public class UserCache { this.a(gameprofile, (Date) null); } - private void a(GameProfile gameprofile, Date date) { + private synchronized void a(GameProfile gameprofile, Date date) { // Paper - synchronize UUID uuid = gameprofile.getId(); if (date == null) { @@ -122,8 +122,9 @@ public class UserCache { String s = gameprofile.getName().toLowerCase(Locale.ROOT); UserCache.UserCacheEntry usercache_usercacheentry = new UserCache.UserCacheEntry(gameprofile, date, null); - if (this.e.containsKey(uuid)) { + //if (this.e.containsKey(uuid)) { // Paper UserCache.UserCacheEntry usercache_usercacheentry1 = (UserCache.UserCacheEntry) this.e.get(uuid); + if (usercache_usercacheentry1 != null) { // Paper this.d.remove(usercache_usercacheentry1.a().getName().toLowerCase(Locale.ROOT)); this.f.remove(gameprofile); @@ -136,7 +137,7 @@ public class UserCache { } @Nullable - public GameProfile getProfile(String s) { + public synchronized GameProfile getProfile(String s) { // Paper - synchronize String s1 = s.toLowerCase(Locale.ROOT); UserCache.UserCacheEntry usercache_usercacheentry = (UserCache.UserCacheEntry) this.d.get(s1); @@ -165,7 +166,7 @@ public class UserCache { return usercache_usercacheentry == null ? null : usercache_usercacheentry.a(); } - public String[] a() { + public synchronized String[] a() { // Paper - synchronize ArrayList arraylist = Lists.newArrayList(this.d.keySet()); return (String[]) arraylist.toArray(new String[arraylist.size()]); @@ -227,8 +228,15 @@ public class UserCache { } + // Paper start public void c() { + c(true); + } + public void c(boolean asyncSave) { + // Paper end String s = this.b.toJson(this.a(org.spigotmc.SpigotConfig.userCacheCap)); + Runnable save = () -> { + BufferedWriter bufferedwriter = null; try { @@ -242,6 +250,14 @@ public class UserCache { } finally { IOUtils.closeQuietly(bufferedwriter); } + // Paper start + }; + if (asyncSave) { + MCUtil.scheduleAsyncTask(save); + } else { + save.run(); + } + // Paper end } -- 2.9.3
