Prune Addon for FTB Chunks

Important

• Version 0.0.2 and below only work with FTB Chunks 2.x. MinecraftPatch by default may install wrong dependencies. Please downgrade to FTB Chunks 2.x and FTB GUI Library 2.x in that case.
• Version 0.0.3 works with FTB Chunks 3.x

Prune Addon

This mod adds admin commands for pruning region and poi files which do not have any chunks claimed by FTB-Chunks.

Possible Usage

• Regenerating chunks without having to reset the world.
• Reducing the size of backup files.
• Reducing the disk size of ridiculously large worlds. 
• Getting rid of abandoned bases on multiplayer servers.

Prune Command

Prunes region and poi files of a dimension.
Removes all the files which do not contain any chunks claimed by FTB-Chunks.

Syntax: /prune [region_files | poi_files] [dimension <dimension>] [do_not_backup <true | false>]

Parameters

• file-type: The types of files which should be pruned, possible values are region_files and poi_files, default:both
• dimension: The dimension to prune the data from. default: overworld
• do_not_backup: If set to true, pruned files will not be backed up. default: false
       Use with extreme caution! true will permanently delete files.

Instructions for Pruning

Make sure  of the following

• Make sure that all the chunks which you want to purge are unloaded.
• You are not in a chunk which you want to be pruned.,
• If multiplayer, no other players are in chunks to be purged.
• Restart the server after the prune command.
• If you see the same files in origin or poi folder as the files in the backup origin and poi folder respectively, then something went wrong. The files you wanted to be purged had loaded chunks on the server so the server saved them again after they were pruned. You can bypass this by killing the server instantly after executing the prune command and preventing the server from saving  loaded chunks. Be careful because you can lose unsaved progress this way.

Limitation for Now

The region files contain an area of 32 x 32 chunks, even if only one of those chunks is claimed the whole file will remain and will not be pruned. Which means that the whole 32 x 32 chunks area will remain the same. (See planned features below)

Planned Features

• Configurable paths for backup location of pruned files,
• Compression of files to be backed up,
• Automated scheduled pruning,
• Pruning of non-claimed chunks stored in the same region file as claimed chunks.
