Webware for Python

Hi

I tested webware 1.0.2 on python 2.6.2 (fedora 12) and came into a bug
that I could find.
from python 2.6 guess_type implementation doesn't support multi threading.
The symptom is an infinite recursion exception on guess_type when it
is called concurrently

Looking in webware trunk I could see it that the exception is catched:


            try:
                mimeType, mimeEncoding = guess_type(filename, False)
            except Exception:
                mimeType = None

I'm not sure this is a good method because python does make an
infinite recursion before sending the exception.
Maybe it is better to prevent it, just by using a mutex:

from threading import Lock
guess_type_lock=Lock()


...

with guess_type_lock:
                mimeType, mimeEncoding = guess_type(filename, False)

This works fine for me.

Thanks
