groundstation is a database, and framework for operating with the database, intended to build distributed knowledge graphs, and then sync them up in hostile network settings.
The core of its implementation is an object store of linked immutable objects that are synced via a gossip protocol.
The current version uses libgit2 as a storage backend, but doesn't use many git primitives, beyond git's objects as a storage medium. Git is deliberately pulled out into a storage driver, however while groundstation doesn't assume that you're using git it does assume you're using something that looks a lot like git.
groundstation hinges on the notion of protocols internally – groundstation core provides you with content addressable storage, but it's up to you to work out what to actually do with that data.
That said, groundstation does ship with some protocol adaptors. Adaptors take
name@domain:adaptor-version, and until such time as a release is
already, everything that ships with groundstation will be released with
email@example.com as the email, ie
groundstation is mostly self contained, and hasn't relied on unreleased features in libgit2 or pygit2 for some time now. Assuming that you have a working and recent libgit2 you should be able to run the test suite by running:
Groundstation should work with the latest stable version of pygit2, which unfortunately still depends on an unreleased version of libgit2. It has been a while since I used new features in pygit2 though, so older versions should work fine as far back as 0.18.
- install libgit2 from the
pip install -r requirements.txt(On OSX you'll need to
export CC=clangfor pycrypto)
You probably want to install those requirements in a virtualenv.
