Hello,

First of all, sorry for the late reply, I have been quite busy lately.

I will re-run the tests with log level set to "info", but I will first
update to the latest revision of the mod_wsgi module. I am using the
following Python snippet to adapt WSGI 1.0 apps to 2.0, they are a set
of decorators for WSGI applications, I hope they are ok although I have
not read the WSGI standard in depth:

---- <snip> ----

class Context(object):
    __slots__ = ("response", "headers")

    def __init__(self):
        self.response = None
        self.headers  = ()
    def __call__(self, response, headers):
        self.response = response
        self.headers  = headers


def wsgi1to2(application):
    """Converts a 1.0 app into a 2.0 app"""
    def wrapper(environ):
        context = Context()
        results = application(environ, context)
        return context.response, context.headers, results
    return wrapper


def returnone(application):
    """Makes a 2.0 app return only one element as result"""
    def wrapper(environ):
        response, headers, results = application(environ)
        return response, headers, "".join(results)
    return wrapper


def fornginx(application):
    """Applies the two above decorators, which is needed for
       a 1.0 application to work inside Nginx.
    """
    return returnone(wsgi1to2(application))

---- </snip> ----

Cheers,
