Cannot change exposed_ value using protocol confiration

[petmakris]

    from rpyc.utils.server import ThreadedServer

    rpyc_protocol_config = {
        'allow_all_attrs': True,
        'allow_public_attrs': True,
        'allow_exposed_attrs': True,
        'exposed_prefix': '',
    }

    t = ThreadedServer(TouchstoneRemoteService,
                       port = 18861,
                       protocol_config=rpyc_protocol_config)
    t.start()

In this example it seems that protocol_config does not affect anything. The exposed_ prefix cannot be changed.

The thing is that the method from core/protocol.py which checks these options is never called:

    #
    def _check_attr(self, obj, name):

        if self._config["allow_exposed_attrs"]:
            if name.startswith(self._config["exposed_prefix"]):
                name2 = name
            else:
                name2 = self._config["exposed_prefix"] + name
            if hasattr(obj, name2):
                return name2
        if self._config["allow_all_attrs"]:
            return name
        if self._config["allow_safe_attrs"] and name in self._config["safe_attrs"]:
            return name
        if self._config["allow_public_attrs"] and not name.startswith("_"):
            return name
        return False

    def _access_attr(self, oid, name, args, overrider, param, default):
        if is_py3k:
            if type(name) is bytes:
                name = str(name, "utf8")
            elif type(name) is not str:
                raise TypeError("name must be a string")
        else:
            if type(name) not in (str, unicode):
                raise TypeError("name must be a string")
            name = str(name) # IronPython issue #10 + py3k issue
        obj = self._local_objects[oid]
        accessor = getattr(type(obj), overrider, None)

        print accessor

        if accessor is None:
            name2 = self._check_attr(obj, name)
            if not self._config[param] or not name2:
                raise AttributeError("cannot access %r" % (name,))
            accessor = default
            name = name2
        return accessor(obj, name, *args)

where _check_attr is never actually called.

You are right. Fix will be in 3.4.4 or greater.
