I just released Spring Python 0.9.1. One of our users spotted an error
in the <a href="http://springpython.webfactional.com/reference/html/
objects.html">IoC container</a> involving constructor arguments, and I
was able to reproduce the problem, patch it, and get it released
quickly to the user community. You can <a href="http://s3browse.com/

===============================

Key Features of Spring Python include:

    * Inversion Of Control - The idea is to decouple two classes at
the interface level. This lets you build many reusable parts in your
software, and your whole application becomes more pluggable. You can
use either the XmlApplicationContext or the
DecoratorBasedApplicationContext.

    * Aspect-oriented Programming - Spring Python provides great ways
to wrap advice around objects. It is utilized for remoting. Another
use is for debug tracers and performance tracing.

    * DatabaseTemplate - Reading from the database requires a
monotonous cycle of opening cursors, reading rows, and closing
cursors, along with exception handlers. With this template class, all
you need is the SQL query and row-handling function. Spring Python
does the rest.

    * Database Transactions - Wrapping multiple database calls with
transactions can make your code hard to read. This module provides
multiple ways to define transactions without making things
complicated.

    * Security - Plugin security interceptors to lock down access to
your methods, utilizing both authentication and domain authorization.

    * Remoting - It is easy to convert your local application into a
distributed one. If you have already built your client and server
pieces using the IoC container, then going from local to distributed
is just a configuration change.

    * Samples - to help demonstrate various features of Spring Python,
some sample applications have been created:
          o PetClinic - Everybody's favorite Spring sample application
has been rebuilt from the ground up using various web containers
including: CherryPy. Go check it out for an example of how to use this
framework.
          o Spring Wiki - Wikis are powerful ways to store and manage
content, so we created a simple one as a demo!
          o Spring Bot - Use Spring Python to build a tiny bot to
manage the IRC channel of your open source project.
