Over the past few months, we've been quietly open-sourcing a set of our core libraries and applications. We've held back on announcing them publicly as the repos form a chain, with one dependent on the last, so it didn't make much sense to announce them to the world until the complete chain was out there. We've now reached that point. Here's what's new: 1. turtle ( https:// github.com/ sociomantic- tsunami/ turtle ). Our utility library for implementing black-box application tests: spawns the tested application as a separate process in a temporary sandbox, then runs a set of auto-discovered test cases. 2. swarm ( https:// github.com/ sociomantic- tsunami/ swarm ). The core client/server library which forms the foundation of our various distributed storage systems. 3. dhtproto ( https:// github.com/ sociomantic- tsunami/ dhtproto ). Based on swarm, defines the protocol for our Distributed Hash Table database -- an in-memory database for quick-access, binary data. The repo also contains the DHT client and a set of tests (based on turtle) for a DHT server implementation. 4. dhtnode ( https:// github.com/ sociomantic- tsunami/ dhtnode ). Based on dhtproto, this is the actual implementation of our DHT server. 5. dlsproto ( https:// github.com/ sociomantic- tsunami/ dlsproto ). Based on swarm, defines the protocol for our Distributed Log Store database -- a disk-based database for batch-read, historical data. The repo also contains the DLS client and a set of tests (based on turtle) for a DLS server implementation. 6. dlsnode ( https:// github.com/ sociomantic- tsunami/ dlsnode ). Based on dlsproto, this is the actual implementation of our DLS server. These new repos are, of course, in addition to our ocean library -- https:// github.com/ sociomantic- tsunami/ ocean/ -- which was open-sourced some time ago. As with ocean, all of these repos are written in a subset of D2 that's compatible with D1. When we've finished our migration to D2, D1 support in the libraries will be phased out.
