Summary: Webserver TypeError: expected read buffer, NoneType found
Initial Comment:
When I'm using the python webserver I got the
following message for every access by my client.
Soryy, I have no experience in Python, so I cannot
help. This is only a report.

This was a fine place to report it; the question is how to
resolve it now that it is reported. The catch is that
cgi.py doesn't seem to have changed, and we're not sure it
should.

We are using Myghty as a webserver, but we have the
problem python 2.4 eats up all the memory of the small
embedded system. So I tried with python 2.5 with the new
memory management...and was stuck at this message.
I reported this message to improve 2.5 development. Sorry
if this was a wrong way to do it.

I suspect that changing
>>> fp = StringIO(qs)
to
>>> fp = StringIO(qs or "")
would fix the problem.
If so, this is arguably a bug in myghty. qs was already
set to "" unless sys.argv[1] or environ['QUERY_STRING']had
a value. Neither of these should ever be None. (They
should be either a string, or not found.)

Thanks for the report. Can I ask how you came to use the
as-yet-unreleased Python 2.5 if you have no experience with
Python? It looks like you are having this problem with
Myghty. Does that require Python 2.5?
FWIW, this looks to me like a problem with Myghty's use of
the cgi module, not a problem with Python itself.
