OpenERP 7.0 and NetRPC

on 8/28/14, 6:33 AM 1,624 views


I have a php application that connect to a 6.0 version of OpenERP using netrpc. I'm now trying to check if I can use the same code to connect my application to a 7.0 version. After analysing the code, I found that it's based on socket communications, so I prepared this code to make somme tests:

import socket
import cPickle
msg = ('common', 'login', 'db_name', 'admin', 'secret')
msg = cPickle.dumps([msg,None])
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print sock.connect_ex(('localhost', 8070))
sock.sendall('%8d%s%s' % (len(msg), True and "1" or "0", msg))
#print sock.recv(8 - len(buf))
#print "put"

def read(socket, size):
    while len(buf) < size:
        print "innn"
            chunk = socket.recv(size - len(buf))
            print "cunk ", chunk
            if chunk == '':
                raise RuntimeError, "socket connection broken"
            buf += chunk
        except Exception, e:
            print e
    return buf

size = int(read(sock, 8))
buf = read(sock, 1)
exception = buf != '0' and buf or False
res = cPickle.loads(read(sock, size))

if isinstance(res[0],Exception):
    if exception:
        raise TinySocketError(ustr(res[0]), ustr(res[1]))
    raise res[0]
    print "res ",res[0]

When I run this code whyle a 6.0 server is running, I got an answer. But with a 7.0 server running, I have a Timeout problem (and I see openerp.service.netrpc_server: starting NET-RPC service on in the log so the netrpc service must be running). So I digged a litte in the OpenERP net-rpc code, and I found that the netrpc server is runned via the netrcp_server.py. After that I discovered that the difference between 6.0 and 7.0 is that in the first one, the function TinySocketServerThread.run was called, but in the second, it wasn't, witch means (If I'm not wrong) that there was no client socket waiting for connection witch explain why I don't get an answer.

So, is there anything wrong with my analysis? Did someone tested to use net rpc with a 7.0 of openerp? Did I miss something to make the netrpc work properly?

After more checking I found this: in the 6.0 version, the netrpc and other service are runned by calling


In openerp-server.py. In 7.0 version, this function is not called nowere, so I added :


In the __init__.py under the service folder in the end of the start_services function : after that, the thread was lunched and I can see that the server did receive the socket call. But I found another problem: in TinySocketClientThread.run function, this line 

ts = openerp.server.netrpc_socket.mysocket(self.sock)

must be replaced by this one

ts = openerp.service.netrpc_socket.mysocket(self.sock)

After that, it worked fine.
