Tornado RPC Library on Google Code

October 18th, 2009

I finished my JSON-RPC and XML-RPC handlers for Tornado, and so I’ve thrown them up on Google Code. Now people can test my JSON-RPC v2.0 implementation on my jsonrpclib library. :) Which is just what everyone was dying to do, I’m sure.

Usage is pretty simple, it’s designed to be a.) pretty transparent and b.) easily ported between XML-RPC and JSON-RPC to compare speed, network transfer, etc. times. For example, here’s the complete code for XML-RPC client (after installing Tornado and the TornadoRPC library):

from tornadorpc.xml import XMLRPCHandler
from tornadorpc import private, start_server

class Handler(XMLRPCHandler):
    def add(self, x, y):
        return x+y
    def ping(self, obj):
        return obj
    @private
    def private(self):
        #should not get called
        return False

start_server(Handler, port=8080)

To use JSON-RPC, you’d just change any instance of xml/XML to json/JSON. There are several benefits to using JSON, such as smaller transfer size, keyword arguments, notifications, etc., but to use it you are required to install my jsonrpclib implementation.

Holy community code, Batman. Facebook has been launching open source projects like crazy in the past few months. (This would be a Good Thing — I think they launched two today just while I refreshed the page!) Things like Cassandra, Thrift, and Hive are great additions to the community, and hopefully the rewards will go both ways. One of the projects I’ve been playing with is Tornado, FriendFeed’s Python web framework. It’s quite simple to dive into if you are familiar with any of the dozens of web frameworks available for Python (like web.py, Pylons, CherryPy, etc.), and it’s very fast. (But, in the immortal words of LeVar Burton, “don’t take my word for it.“)
