Bertlet, BERT-RPC in Eventlet

Bertlet is a Python implementation of the BERT-RPC protocol written in Eventlet to make concurrency trivial.

Warning: Bertlet is in early stages of development. It does not yet cover the entire BERT-RPC protocol. See the Roadmap for more information.

Features

Bertlet is at version 0.2. Current features supported:

• BERT-RPC cast and call
• SSL
• Middleware
• Gzip
• Preliminary informational berp support
• "Private" functions are not accessible; anything beginning with an underscore
• Protocol error handling

See Roadmap for upcoming features.

Requirements

• Eventlet >= 0.9.5
• python-bert

Optional:

• ssl (either Python >= 2.6 or pyopenssl)

Usage

Bertlet is intended to be incredibly easy to use. BERT-RPC uses modules and functions to expose functionality; Bertlet uses Python modules and functions in the same manner. Creating a service with Bertlet is a two-step process: create your modules and functions, then expose them with a Server object.

Example module foo.py:

def bar():
    return "Hello, world!"

Example server runner:

#!/usr/bin/env python
from bertlet import serve
import foo

serve(foo, certfile="mycert.crt", keyfile="mycert.key")

It's that simple. Your BERT-RPC service is now running on 2133 with the foo module exposing the bar function. Note: this example also shows how SSL is used.
