pydnode

pydnode is a dnode protocol implementation in python.

install

git clone [email protected]:ybrs/pydnode.git

cd pydnode && virtualenv env && ./env/bin/python setup.py develop

why?

because there is only one implementation in python, and it requires twisted (which i'm not a fan) and hasn't been updated in two years (not sure if it works)

and beyond the obvious technical motivation, it's exceedingly simple... because I can

pros & cons

pros:

• it basically works, though has some missing parts

cons:

• doesn't support and no intention to support links
• some protocol functions are missing, such as cull etc.
• probably has memory leaks
• no dnode server implementation
• no timeouts (use coroutines)
• not production tested

usage

on your server.js:

var dnode = require('../..');
var server = dnode(function (remote, conn) {
   this.fn = function(foo, callback){
       callback(foo, function (o, cb){
          console.log(o)
          cb("done")
       })
   }    
})
server.listen(7070);

and call it from python

from pydnode import dnode
def output(f, remoteCallback):
    print f
    if remoteCallback:
        remoteCallback("Foo", lambda x: output(x, None))

client = dnode.DNodeClient("127.0.0.1", 7070)
client.connect()
client.calldnodemethod("fn", "foo", output)
