[patch] core.handlers.wsgi.py doesn't properly handle blank CONTENT LENGTH with patch

[anonymous]

I was getting some strange errors trying to do some AJAX-type stuff and kept getting a strange traceback. I traced it to the wsgi.py:122.

if CONTENT LENGTH = , it fails with a Value Error.

Here is a patch:
replace line 122 with these:

try:

self._raw_post_data = self.environwsgi.input.read(int(self.environCONTENT_LENGTH))

except ValueError:

self._raw_post_data = self.environwsgi.input.read(0)

return self._raw_post_data

Do you need the read(0) here instead of just setting self._raw_post_data = '' ?

I've encountered this bug too.

When I'm POSTing empty form under Lighttpd it does not sets CONTENT_LENGTH variable, and Django fails

Here is my traceback:

But since that ticket is already applied I'm marking this one as a dupe instead.
