Introduction

This is a small tool that takes torrents from a rss feed and starts them on rtorrent.

Usage

This section explains how to use the tool. Typically this tool can be run by simply running ./main.py with the right command line arguments.

The following example will fetch the RSS feeds from http://rss-feed.host/rss-feed and start all torrents on the rtorrent instance behind the uri http://rtorrent.host/RPC2.

~/bridge-from-torrent-rss-feed-to-rtorrent$ main.py \
--rss-feed-uri=http://rss-feed.host/rss-feed \
--xml-rpc-uri=http://rtorrent.host/RPC2

The following section explains all available command line arguments.

Command line arguments

The tool accepts the following command line arguments:

--xml-rpc-uri

This argument sets the uri to the rtorrent http xmlrpc interface. This argument is required.

Allowed values

Any uri string is allowed.

Default value

This argument is required but has no default value.

Example usage

--xml-rpc-uri=http://host-of-rtorrent/RPC2

--rss-feed-uri

This argument sets the uri to the RSS feed. This argument is required.

Allowed values

Any uri string is allowed.

Default value

This argument is required but has no default value.

Example usage

--rss-feed-uri=http://host-of-rss-feed/path-to-rss-feed

--rss-feed-cookie-key

This argument sets a cookie key to be used when retrieving the RSS feed and when fetching the torrent that a RSS feed link points to. This argument needs to be combined with a --rss-feed-cookie-value argument. The tool then interprets this argument as the cookie key and the next --rss-feed-cookie-value argument as the value of the cookie. The cookie key must argument must come before the cookie value argument.

Allowed values

Any string is allowed.

Default value

This argument is optional and has no default value.

Example usage

This example sets the cookie foo=bar when sending requests to fetch the RSS feed or fetch the torrent file referenced by a RSS feed link.

--rss-feed-cookie-key=foo --rss-feed-cookie-value=bar

--rss-feed-cookie-value

This argument sets a cookie value to be used when retrieving the RSS feed and when fetching the torrent that a RSS feed link points to. This argument needs to be combined with a --rss-feed-cookie-key argument. The tool interprets this argument as the value of the cookie and the previous -rss-feed-cooki-key argument as the key of the cookie. The cookie value argument must come after the cookie key argument.

Allowed values

Any string is allowed.

Default value

This argument is optional and has no default value.

Example usage

This example sets the cookie foo=bar when sending requests to fetch the RSS feed or fetch the torrent file referenced by a RSS feed link.

--rss-feed-cookie-key=foo --rss-feed-cookie-value=bar

--verbose

By default the tool runs verbosely (--verbose=yes), meaning that it outputs informational messages. When setting up the script to run as a cronjob it is wise to set --verbose=no to avoid causing crond to send emails when all is fine. It is better when crond only sends an email when it encounters a problem and it requires the attention of a human.

Allowed values

Default value

Example usage

This example disables verbose outputs.

--verbose=no

Installation

A typical installation would add the script as a cronjob that runs regularily every few minutes. This has the effect that new torrents in the rss feed are so started and downloaded. It further allows the script to send failures through the crond daemon. Please note that the script should not generate output when running as a cronjob so long all is fine.

Requirements

These are the requirements for this tool to work:

python3
python3-feedparser
python3-requests

Install requirements on a debian based linux distribution

This section explains how to install the requirements on a debian based linux distribution.

~$ sudo apt install python3 python3-feedparser python3-requests

rtorrent requirements

Further rtorrent has to be installed with xmlrpc enabled. This can be achieved by configuring the .rtorrent.rc configuration file to contain the following.

# enable scgi support
scgi_port = 127.0.0.1:5000

apache2 requirements

Further the scgi port enabled in rtorrent needs to be mounted in a apache2 site. This can be achieved by configuring a site (i.e. /etc/apache2.sites-enabled/default) to contain the SCGIMount directive.

Note that it is wise to not make the xml rpc interface accessible to anyone. Anyone would then be allowed to remotely control your rtorrent instance! Therefore this example further adds basic password protection to provide a minimum of security. Adding simple authentication makes it easy to provide the username and password in the xml rpc uri.

<VirtualHost *:80>
	...
	SCGIMount /RPC2 127.0.0.1:5000
	<Location /RPC2>
		AuthName "Auth required"
		AuthType Basic
		AuthBasicProvider file
		AuthUserFile /path-to/.htpasswd
		Require user allowed_user
	</Location>
	...
</VirtualHost>

Assuming that the "allowed_user" has the password "verysecurepassword" and runs on the host "rtorrent.host", the XML rpc uri argument would look like the following.

--xml-rpc-uri=http://allowed_user:verysecurepassword@rtorrent.host/RPC2

Remark: Transdroid

Having configured rtorrent and apache2 like this, we now also have set up our rtorrent instance to be controlled remotely with Transdroid from an Android device.

Installation as a cronjob

Make sure you have installed all the requirements
Clone repository; this should automatically checkout the master branch which tracks the latest stable changeset
Run the script to test if the arguments are fine

~/bridge-from-torrent-rss-feed-to-rtorrent/$ main.py --rss-feed-uri=http://rss-feed.host/rss-feed --xml-rpc-uri=http://rtorrent.host/RPC2

Add cronjob by running as the user under which the cronjob should run by typing:

~/$ crontab -e

Add the following lines at the end to run the script every 5 minutes:

*/5 * * * * /home/$user/bridge-from-torrent-rss-feed-to-rtorrent/main.py --xml-rpc-uri=http://rtorrent.host/RPC2 --rss-feed-uri=http://rss-feed.host/rss-feed --verbose=no

Save the changes and exit the editor
Done

Please note that it may be wise to write a simple intermediary script that is run by the cronjob and makes the crontab -e easier. A typical sample script could be:

#!/bin/bash

# REMARK: when running as a cronjob it needs to be an absolute path to the script
# set the $USER variable to the actual user that this command is run with if the
# $USER environment variable is not available
#USER=nobody

# change to the directory where the tool is installed
cd /home/$USER/bridge-from-torrent-rss-feed-to-rtorrent

# pull latest version
git pull --quiet

# prepare to run the command
xml_rpc_uri="http://rtorrent.host/RPC2"
rss_feed_uri="http://rss-feed.host/rss-feed"

# run the command
/home/$USER/bridge-from-torrent-rss-feed-to-rtorrent/main.py \
--xml-rpc-uri="$xml_rpc_uri" \
--rss-feed-uri="$rss_feed_uri" \
--verbose=no

Changelog

You can review the changelog of all past releases here.

Contributing

Please read the contributing guidelines before starting to work on a patch, writing issues or file a pull request. The contributing guidelines are available here.

Release

This section outlines how to make a release. The CHANGELOG.md is in a format that allows the usage of the tool chag.

Install tools

chag

This is a simple command line tool that helps to manage the changelog file and can create annotated tags with the contents contained in the changelog file. Because this tool is so useful the following sections are based on that and require it to be installed. The installation of the tool is easy:

# clone the repository
# note that this version includes some pull requests
# that are not available in the original repository
~$ git clone https://github.com/dpsenner/chag.git

# add a symbolic link to the latest version of chag
~$ sudo ln -s /usr/local/bin/chag `pwd chag/chag`

Prepare the release

Checkout develop by running git checkout develop
If there are any feature branches that should be included in the release, merge them into branch develop: git merge $featurebranch
Check the output of chag latest, it should be:

$ chag latest
Unreleased

If there is none, update the CHANGELOG.md file to contain a section ## Unreleased
Commit the changes
Verify if the unreleased changelog contains all the changes that were made. This can be done by running:

$ chag contents Unreleased

Run chag update $version. This should update ## Unreleased to read as ## $version - $today
Commit the changes
Create release branch git branch release/v$version
Run chag next. This should update CHANGELOG.md to contain once more the section ## Unreleased.
Push the new head of develop: git push

Make the release

Please note that the following assumes that no release branch was made.

Checkout master: git checkout master
Merge the changes that should be released: git merge $releasebranch
Push the new head of master: git push
Tag the release: chag tag --sign --addv
Push the tags: git push --tags
Eventually remove the now released release branch:
- git branch -d $releasebranch
- git push origin --delete $releasebranch
- Remember to run git fetch --all --prune on all other machines
