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:
