This is a package mainly for my own use, but others may find it useful. I receive tv programmes from a variety of sources, each with their own specific needs, but there are three common problems I have.
- I need to know when there is something new
- I need to keep any temporary working directories clean
- I need to sort things into the correct folder automatically.
To address this, I shall use the following solutions.
To do this, I have an "unwatched" folder which simply contains symlinks to other parts of the filesystem. When I've watched something, I just remove the symlink.
When something has finished downloading, it should be moved. But some methods of downloading, such as torrents, still need the files for a certain amount of time, such as for seeding. They should not be moved in these circumstances.
My plan for torrents is to use an API to the torrent server to see when something has finished downloading. If it has, a hardlink will be created in the target destination folder, and a symlink to the target destination in the unwatched folder. When the torrent has finished seeding the hardlink in the torrent working dir will then be removed. I chose not to use a symlink between the target and working dirs as the target dir is often accessed over a samba share that can't see this dir, and because I wouldn't want to do a move, create-symink-in-old-location as this may break transmission.
I have an existing script I use with get-iplayer that does this, which I shall adapt into a library to do most of the work for this.
There will be four parts to my solution - a library for the sorting, a client that moves files, a transmission script that keeps track of transmission and calls the client to do moving, and a get-iplayer script that does something similar
The client is intended to have the following synopsis:
tv-management --move-file [--add-to-unwatched] filename
This will find the correct directory to move the given file to and move it there. If a file already exists with the same name in the target directory, it will check if they are the same inode. If so it will simply remove filename.
The --add-to-unwatched flag will add a symlink in the unwatched folder.
tv-management --hardlink-file [--add-to-unwatched] filename
This will create a hardlink of filename in the determined target directory.
