A transmission maintenance tool

Say you are downloading very large numbers from the internet which you then share with others, and say also that those very large numbers occupy a lot of space on your hard disk drive.

The people who tell you where to find the large number want you to keep sharing those numbers equitably, and you yourself want that too! Large numbers however occupy a lot of space, but after a while you can stop sharing the numbers, and nobody minds that at all (because hopefully the very large number has propagated enough).

So, this tool helps you keep the disk space usage of seeded torrents in check by letting you define an amount of time that torrents get seeded for, or until their minimum ratio requirement has been met. If so, it'll delete data.

This is similar to autoremove-torrents, except it works with the version of transmission that I run (and no other torrent client).

Installation

cargo --git git://github.com/antifuchs/gearbox-maintenance gearbox-maintenance

Configuration

The configuration language is Rhai, a scripting language that works pretty well for configuration files.

Here's an example config file:

[
  rules(
      transmission("http://localhost:9091/transmission/rpc")
        .user("transmission")
        .password("secret")
        .poll_interval("20min"),
      [
          delete_policy("horse_seasons",
                        on_trackers(["tracker-hostname.horse"])
                          .min_file_count(2),
                        matching()
                          .max_ratio(2.3)
                          .min_seeding_time("2 days")
                          .min_seeding_time("14 days")),
          delete_policy("horse_episodes",
                        on_trackers(["tracker-hostname.horse"])
                          .max_file_count(1),
                        matching()
                          .max_ratio(2.3)
                          .min_seeding_time("24 hours")
                          .max_seeding_time("3 days"))
      ],
  )
]

You can also use rhai's module system to import files in the same directory.

Invocation

By default, this tool takes no action: gearbox-maintenance config.rhai will connect to the transmission instances you specify, and log what actions it would take.

To have it actually delete data, run gearbox-maintenance -f config.rhai.

The default log level is gearbox-maintenance=info. You can increase logging intensity by setting the environment variable RUST_LOG=debug, but beware: some dependencies are very very loud. See the env_logger convention docs for details on how to tune the log level.
