Perspective Broker

"This isn't a professional opinion, but it's probably got enough
internet to kill you." --glyph

Introduction
============

This is a broker for proxies for and copies of objects.  It provides a
translucent interface layer to those proxies.

The protocol is not opaque, because it provides objects which represent the
remote proxies and require no context (server references, IDs) to operate on.

It is not transparent because it does I{not} attempt to make remote objects
behave identically, or even similarly, to local objects.  Method calls are
invoked asynchronously, and specific rules are applied when serializing
arguments.

To get started, begin with L{PBClientFactory} and L{PBServerFactory}.

    This error can be raised to generate known error conditions.

    When a PB callable method (perspective_, remote_, view_) raises
    this error, it indicates that a traceback should not be printed,
    but instead, the string representation of the exception should be
    sent.
    Nr1r6r7r8r<r<as��r7r<c��eZdZdZd�Zy)�RemoteErrora�
    This class is used to wrap a string-ified exception from the remote side to
    be able to reraise it. (Raising string exceptions is no longer possible in
    Python 2.6+)

    The value of this exception will be a str() representation of the remote
    value.

        raised on the remote end.
    @type remoteType: C{str}

    per*spec*tive, n. : The relationship of aspects of a subject to each
    other and to a whole: 'a perspective of history'; 'a need to view
    the problem in the proper perspective'.

    This is a Perspective Broker-specific wrapper for an avatar. That
    is to say, a PB-published view on to the business logic for the
    system's concept of a 'user'.

    The concept of attached/detached is no longer implemented by the
    framework. The realm is expected to implement such semantics if
    needed.

        This method is called when a network message is received.

        @arg broker: The Perspective Broker.

        @type message: str
        @arg message: The name of the method called by the other end.

        @type args: list in jelly format
        @arg args: The arguments that were passed by the other end. It
                   is recommend that you use the `unserialize' method of the
                   broker to decode this.

        @type kwargs: dict in jelly format
        @arg kwargs: The keyword arguments that were passed by the
                     other end.  It is recommended that you use the
                     `unserialize' method of the broker to decode this.

        @rtype: A jelly list.
        @return: It is recommended that you use the `serialize' method
                 of the broker on whatever object you need to return to
                 generate the return value.

    A default IPerspective implementor.

    This class is intended to be subclassed, and a realm should return
    an instance of such a subclass when IPerspective is requested of
    it.

    A peer requesting a perspective will receive only a
    L{RemoteReference} to a pb.Avatar.  When a method is called on
    that L{RemoteReference}, it will translate to a method on the
    remote perspective named 'perspective_methodname'.  (For more
    information on invoking methods on other objects, see
    L{flavors.ViewPoint}.)

    A translucent reference to a remote object.

    I may be a reference to a L{flavors.ViewPoint}, a
    L{flavors.Referenceable}, or an L{IPerspective} implementer (e.g.,
    pb.Avatar).  From the client's perspective, it is not possible to
    tell which except by convention.

    I am a "translucent" reference because although no additional
    bookkeeping overhead is given to the application programmer for
    manipulating a reference, return values are asynchronous.

        Note that if you set up the factory to reconnect, you will need to
        implement extra logic to prevent automatic reconnection after this
        is called.

    Server factory for perspective broker.

    Login is done using a Portal object, whose realm is expected to return
    avatars implementing IPerspective. The credential checkers in the portal
    should accept IUsernameHashedPassword or IUsernameMD5Password.

    Alternatively, any object providing or adaptable to L{IPBRoot} can be
    used instead of a portal to provide the root object of the PB server.

            over the wire.
