Unpacker Poller

About

This application runs as a daemon on your Deluge host. It checks for completed downloads and extracts them so Radarr and/or Sonarr may import them.

There are a handful of options out there for extracting and deleting files after Deluge downloads them. I just didn't care for any of them, so I wrote my own. I wanted a small single-binary with reasonable logging that can extract downloaded archives and clean up the mess after they've been imported. Why a separate binary instead of a Deluge plugin? Because I like Go more than Python and I wanted a fun project to work on over a weekend.

Logic

The application kicks up a go routine for Deluge and another for each of Radarr and Sonarr (if you include configs for them). These go routines just poll their respective applications for transfers/queued items. The items are stored. The interval of these pollers is set in the config file. 2-10 minutes is good.

Another go routine checks (the internal data) for completed downloads. When it finds an item in Deluge that matches an item in Sonarr or Radarr the download location is checked for a .rar file. If an extractable archive exists, and Sonarr/Radarr have status=Completed from Deluge this application will extract the file. When the item falls out of the (Radarr/Sonarr) queue, the extracted files are removed.

Tags are currently mentioned, but nothing uses them. I figured I would match tags before I started getting data from the APIs. Once I realized I was able to match d.Name with q.Title I didn't need to use tags. It all works out automagically.

Installation

• Setup a working Go build environment.
• make install (mac) or sudo make install (linux)
• cross your fingers.

If you don't want to use the Makefile, manual installation is pretty easy.

• Build the app like any other Go app (or run make).
• Copy the binary to /usr/local/bin
• Make a config folder: sudo mkdir /usr/local/etc/unpacker-poller
• Copy the example config: sudo cp up.conf.example /usr/local/etc/unpacker-poller/up.conf
• On macOS, copy the launchd file: cp startup/launchd/* ~/Library/LaunchAgents
• On Linux, copy the systemd unit: sudo cp startup/systemd/* /etc/systemd/system

After the app is installed, update your deluge, sonarr and radarr configuration in /usr/local/etc/unpacker-poller/up.conf. The app works without Sonarr or Radarr configs, but you should have at least one to make it useful.

• Start the service, Linux: sudo systemctl daemon-reload ; sudo systemctl start unapcker-poller
• Start the service, macOS: sudo launchctl load ~/Library/LaunchAgents/com.github.davidnewhall.unpacker-poller.plist

Troubleshooting

The http_ config options are for basic http auth. Most users will need to leave these blank. I was using them to test my connection through an authenticated nginx proxy. I did not test with basic auth enabled in Sonarr/Radarr. They may or may not work for that. If you need different features, open an Issue and let me know. Generally, you'll point all endpoints at localhost, without nginx and without basic auth.

• Log file is (hopefully) at /usr/local/var/log/unpacker-poller.log
• On macOS, Deluge log is at ~/.config/deluge/deluged.log
• I haven't tested any of this on Linux, feedback welcomed.

If transfers are in a Warning or Error state they will not be extracted. Try the Force Recheck option in Deluge.

Notes

While writing this, I kept finding Deluge unresponsive. After finding and inspecting the Deluge log file, I found that the app was running out of open files. Turns out this was causing a lot of issues on my server. I have a Mac. Check this out if you're in the same boat: http://blog.mact.me/2014/10/22/yosemite-upgrade-changes-open-file-limit
