From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Antony Riley <antony@cyberiantiger.org> Date: Tue, 29 Mar 2016 08:22:55 +0300 Subject: [PATCH] Sanitise RegionFileCache and make configurable RegionFileCache prior to this patch would close every single open region file upon reaching a size of 256. This patch modifies that behaviour so it closes the the least recently used RegionFile. The implementation uses a LinkedHashMap as an LRU cache (modified from HashMap). The maximum size of the RegionFileCache is also made configurable. diff --git a/src/main/java/net/minecraft/world/level/chunk/storage/RegionFileStorage.java b/src/main/java/net/minecraft/world/level/chunk/storage/RegionFileStorage.java index df099d4c7f101f50d40dae99b45c271b02712434..491035aaefff4ee96435ec5d3f9417e28eae0796 100644 --- a/src/main/java/net/minecraft/world/level/chunk/storage/RegionFileStorage.java +++ b/src/main/java/net/minecraft/world/level/chunk/storage/RegionFileStorage.java @@ -39,7 +39,7 @@ public final class RegionFileStorage implements AutoCloseable { if (regionfile != null) { return regionfile; } else { - if (this.regionCache.size() >= 256) { + if (this.regionCache.size() >= io.papermc.paper.configuration.GlobalConfiguration.get().misc.regionFileCacheSize) { // Paper - Sanitise RegionFileCache and make configurable ((RegionFile) this.regionCache.removeLast()).close(); }
