Helper programs for torrent hosting

First extract the info-hash:

torrent-sanitize -h $tmpfile

If it returns errors (status code != 0) you probably don't want the torrent.

It might be a good idea to sync modifications for an info hash, so lock with a file like /tmp/torrent-update-$infohash.lock

The binaries in this source will try to do atomic updates, i.e. first write a temporary file in the same directory, then rename it to the real file.

Run more checks, change some meta data:

torrent-sanitize -s -v --url-filter url-filter.example --meta-filter-text 'comment|created by' --meta-filter-number 'creation date' --meta-add-string 'comment=uploaded on http://my-torrent-hosting.example.com/' $tmpfile $tmpfile

Update announce urls:

torrent-merge -f url-filter.example $destfile $tmpfile

torrent-merge -f url-filter.example $oldtorrent
