[Ironpython-users] socketFile.readline never returns

[Claudio C]

__socketFile is created by this method

def connect(hostName) :
    import errno
    global __connSocket
    global __socketFile
    __connSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    __connSocket.setsockopt(socket.SOL_TCP, socket.TCP_NODELAY, 0)
    try:
        ret = __connSocket.connect_ex((hostName, __connPort))
    except:
        ret = 101 # ENETUNREACH, Network is unreachable
    if ret == 0:
        __socketFile = __connSocket.makefile("r+", __socketBufSize)
    return ret
