This is the second prototype of NEO. The design is described in:

    http://www.nexedi.org/workspaces/neo

TODO

    - Handling connection timeouts.

    - Handling write timeouts.

    - IdleEvent for a certain message type as well as a message ID.

    - Flushing write buffers only without reading packets.

    - Garbage collection of unused nodes.

    - Stopping packet processing by returning a boolean value from
      a handler, otherwise too tricky to exchange a handler with another.

    - History.

    - Multiple undo.

    - Expiration of temporariry down nodes.

Requirements

    - Python 2.4 or later

    - ctypes http://python.net/crew/theller/ctypes/

    - MySQLdb http://sourceforge.net/projects/mysql-python

    - Zope 2.8 or later

Installation

1. In zope:

   a. Copy neo directory to /path/to/your/zope/lib/python

   b. Edit your zope.conf,  remove the `zodb_zb` section that refers to
      FileStorage, and replace it with :

      %import neo
      <zodb_db main>
          # Main FileStorage database
          <NEOStorage>
                master_nodes 127.0.0.1:10010 127.0.0.1:10011
                name main
          </NEOStorage>
          mount-point /
      </zodb_db>

   c. Start zope

2. In a python script:

   a. Set your PYTHONPATH in order to be able to import Zope lib:

     $ export PYTHONPATH=/path/to/your/zope/lib/python:$PYTHONPATH

   b. Just create the storage object and play with it:

   from neo.client.NEOStorare import NEOStorage
   s = NEOStorage(master_addr="127.0.0.1", master_port=10010, name="main")
   ...
