    The following code produces a type error, but from what I can tell it does comply with PEP-333. 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.

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    (This issue should be closed; it is superseded by the fix for 10155 in Python 3.2.)
