The following code produces a type error, but from what I can tell it does comply with PEP333. This issue appeared using Python 3.1.1 and 3.1.2 on both Windows and Ubuntu. I have only tried the 32 bit versions. Works fine in Python 2.6.5.12 but I guess thats irrelevant.

def application(environ, start_response):
	start_response('200 OK',[('Content-type','text/html')])
	return ['<html><body>Hello World!</body></html>']
	
from wsgiref.handlers import CGIHandler
CGIHandler().run(application)

Yes, CGIHandler is broken in 3.0-3.1; wsgiref in general has been in limbo until the whole issue of py3k-WSGI is sorted. This seems to be happening now in PEP 3333.

Attached patch to make CGIHandler use the byte interfaces for stdin/stdout, which allows the write calls to work and provides byte streams to the WSGI application as required by PEP 3333.

(This issue should be closed; it is superseded by the fix for 10155 in Python 3.2.)
