REDsym

REDsym uses existing metadata saved by Whatmanager2 (https://github.com/karamanolev/WhatManager2) to create a symlinked mirror directory.

It uses the ReleaseInfo2.txt files to extract: artists names, album name, year, codec, Catalogue number... and create the mirrored structure.

REDsym does not modify or delete any of the source files or folders to be symlinked.

It turns this structure:

$ tree ~/WM2/12345/album/
.
│── ABC.mp3
└── DEF.mp3

into this structure:

$ tree ~/redsym/
.

Tested with

• Python 3.4
• Linux (Ubuntu 14.04)
• Gazelle trackers metadata (RED, WCD)

Requires

• python-ftfy (to fix encoding issues)
• mysql
• A filesystem that supports os.symlink

Configuration

Configure folders, mysql database name/user/pass in "settings.py".

Running the script

$python3 redsym.py update

Docker

Network

Create network used for inter-container communication between the database container and the application container:

sudo docker network create --internal redsym

Database container

Create a volume to store MariaDB's persistent data:

sudo docker volume create redsym-mariadb-data

Create the database container:

sudo docker run --rm -d \
	--name redsym-mariadb \
	--network redsym \
	--mount type=volume,src=redsym-mariadb-data,dst=/var/lib/mysql \
	-e MYSQL_RANDOM_ROOT_PASSWORD=yes \
	-e MYSQL_DATABASE=REDsym \
	-e MYSQL_USER=redsym \
	-e MYSQL_PASSWORD=redsym \
	mariadb:10.2 \
	--character-set-server=utf8mb4 \
	--collation-server=utf8mb4_unicode_ci

Application container

Build image based on Dockerfile found in the current directory: sudo docker build --tag redsym .

Copy the settings.py file, e.g. mkdir conf && cp REDsym/settings.py conf/ and edit it. Set DB_HOST = 'redsym-mariadb', this is the name of the MariaDB container. For example:

rootdir_wcd = ''

rootdir_red = '/mnt/music-dl/'

redsym_dir = '/mnt/music-lib/'

DB_HOST = 'redsym-mariadb'
DB_NAME = 'REDsym'
DB_USER = 'redsym'
DB_PASS = 'redsym

Run an instance of REDsym based on the image we built:

sudo docker run --rm -it \
	--name redsym \
	--network redsym \
	--mount type=bind,src=/mnt/music-dl/,dst=/mnt/music-dl/,readonly \
	--mount type=bind,src=/mnt/music-lib/,dst=/mnt/music-lib/ \
	--mount type=bind,src=$(pwd)/conf/settings.py,dst=/srv/redsym/REDsym/settings.py,readonly \
	redsym

This runs python3 /srv/redsym/redsym.py update, as seen on the last line of the Dockerfile.
