This is a pre-production deployment of Warehouse, however changes made here WILL affect the production instance of PyPI.
Project Description

Wouldn’t it be nice if writing correct WSGI middleware was this simple?

>>> from wsgi_lite import lite, lighten

>>> def latinator(app):
...
...     # Make sure that `app` can be invoked via the Lite protocol, even
...     # if it's a standard WSGI 1 app:
...     app = lighten(app)
...
...     @lite
...     def middleware(environ):
...         status, headers, body = app(environ)
...         for name, value in headers:
...             if name.lower()=='content-type' and value=='text/plain':
...                 break
...         else:
...             # Not text/plain, pass the request through unchanged
...             return status, headers, body
...
...         # Strip content-length if present, else it'll be wrong
...         headers = [
...             (name, value) for name, value in headers
...                 if name.lower() != 'content-length'
...         ]
...         return status, headers, (piglatin(data) for data in body)
...
...     return middleware

Using just two decorators, WSGI Lite lets you create correct and compliant middleware and applications, without needing to worry about start_response, write and close calls. And with those same two decorators, it also lets you manage resources to be released at the end of a request, and automatically pass in keyword arguments to your apps or middleware that are obtained from the WSGI environment (like WSGI server extensions or middleware-supplied parameters such as request or session objects).

For more details, check out the project’s home page on BitBucket, and scroll down to the table of contents.

WSGI Lite is currently only available for Python 2.x (tested w/2.3 up to 2.7) but the source should be quite portable to 3.x, as its magic is limited to inspecting function argument names, and cloning functions using new.function().
