Gruvi is a new I/O library for Python. It uses pyuv and coroutines based on python-fibers to provide a synchronous programming model for evented IO. Gruvi is similar in objective to gevent and asyncio but it has its own unique design. Some cool features: * Uses a transport/protocol API (no monkey patching). * Comes with an SSL transport that should scale on all platforms including Windows. * Comes with high-performance HTTP client and server implementations (based on the Node.js http-parser), a D-BUS client, and a JSON-RPC client and server. * Use regular Python function call syntax to call potentially blocking functions. When a function blocks, the current fiber is suspended until the operation completes. * Has a concurrent.futures like fiber and thread pool. * Comes with thread-safe synchronization primitives.
