Summary: patch 1079734 broke cgi.FieldStorage w/ multipart post req.
Initial Comment:
Patch 1079734 "Make cgi.py use email instead of rfc822
or mimetools" seems to have broken the cgi.FieldStorage
in cases where the request is a multipart post (for
instance, when a file upload form field is used).
See the attached test program.
With cgi.py revision <1.83 (python 2.4 for instance) I
get the expected results;
374
FieldStorage(None, None, [FieldStorage('param1', None,
'Value of param1'), FieldStorage('param2', None, 'Value
of param2'), FieldStorage('file', '', ''),
FieldStorage(None, None, '')])
but with cgi.py rev 1.83 (current) I get this:
374
FieldStorage(None, None, [FieldStorage('param1', None,
'')])
Another thing that I observed (which isn't reproduced
by this test program) is that cgi.FieldStorage.__init__
never completes when the fp is a socket-file (and the
request is again a multipart post). It worked fine with
the old cgi.py.

The email.HeaderParser module that is now used for parsing
headers consumes the rest of the body of the message when it
is used. If there was some way of telling the parser to stop
reading when it got to the end of the headers, I think this
problem would be fixed. Unfortunately, there is no external
interface to the email module's parser that lets us do this.
I hope we can come up with a reasonable solution that does
not involve reverting to using deprecated modules.
Thanks for the test case.
