From f939bbb2d0d67fc1a7ba5c1e05c553fd79bd090c Mon Sep 17 00:00:00 2001 From: Spottedleaf Date: Sat, 1 Jun 2019 13:00:55 -0700 Subject: [PATCH] Chunk debug command Prints all chunk information to a text file into the debug folder in the root server folder. The format is in JSON, and the data format is described in MCUtil#dumpChunks(File) The command will output server version and all online players to the file as well. We do not log anything but the location, world and username of the player. Also logs the value of these config values (note not all are paper's): - keep spawn loaded value - spawn radius - view distance Each chunk has the following logged: - Coordinate - Ticket level & its corresponding state - Whether it is queued for unload - Chunk status (may be unloaded) - All tickets on the chunk Example log: https://gist.githubusercontent.com/Spottedleaf/0131e7710ffd5d531e5fd246c3367380/raw/169ae1b2e240485f99bc7a6bd8e78d90e3af7397/chunks-2019-06-01_19.57.05.txt For references on certain keywords (ticket, status, etc), please see: https://bugs.mojang.com/browse/MC-141484?focusedCommentId=528273&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-528273 https://bugs.mojang.com/browse/MC-141484?focusedCommentId=528577&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-528577 diff --git a/src/main/java/com/destroystokyo/paper/PaperCommand.java b/src/main/java/com/destroystokyo/paper/PaperCommand.java index 352a39dcb3..4a7939472d 100644 --- a/src/main/java/com/destroystokyo/paper/PaperCommand.java +++ b/src/main/java/com/destroystokyo/paper/PaperCommand.java @@ -28,14 +28,14 @@ public class PaperCommand extends Command { public PaperCommand(String name) { super(name);
