From 8befd3b3ec4606c96161450e60dc63ca5d7d1c8e Mon Sep 17 00:00:00 2001

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
