Summary: AttributeError thrown by urllib.open_http
Initial Comment:
In 2.3b2, looks like an error condition isn't being picked up
on line 300 or 301 of urllib.py.
The code that triggered this traceback was simply:
url = urllib.urlopen(action, data)
Traceback (most recent call last):
File "autospamrep.py", line 170, in ?
current_page = handle_spamcop_page(current_page)
File "autospamrep.py", line 140, in handle_spamcop_page
url = urllib.urlopen(action, data)
File "/Library/Frameworks/Python.framework/Versions/2.3/
lib/python2.3/urllib.py", line 78, in urlopen
return opener.open(url, data)
File "/Library/Frameworks/Python.framework/Versions/2.3/
lib/python2.3/urllib.py", line 183, in open
return getattr(self, name)(url, data)
File "/Library/Frameworks/Python.framework/Versions/2.3/
lib/python2.3/urllib.py", line 308, in open_http
return self.http_error(url, fp, errcode, errmsg, headers,
data)
File "/Library/Frameworks/Python.framework/Versions/2.3/
lib/python2.3/urllib.py", line 323, in http_error
return self.http_error_default(url, fp, errcode, errmsg,
headers)
File "/Library/Frameworks/Python.framework/Versions/2.3/
lib/python2.3/urllib.py", line 551, in http_error_default
return addinfourl(fp, headers, "http:" + url)
File "/Library/Frameworks/Python.framework/Versions/2.3/
lib/python2.3/urllib.py", line 837, in __init__
addbase.__init__(self, fp)
File "/Library/Frameworks/Python.framework/Versions/2.3/
lib/python2.3/urllib.py", line 787, in __init__
self.read = self.fp.read
AttributeError: 'NoneType' object has no attribute 'read'

HTTPResponse.read returns '' if its .fp is None, but the
backwards-compat HTTP class' .getfile() just returns self.file,
which it previously grabbed from HTTPResponse in .getreply().
Wild guess: maybe HTTP.getreply should just do
self.file = response
rather than
self.file = response.fp
The object returned by HTTP.getfile() was documented as
returning an object supporting .readline() and .readlines(),
while HTTPResponse only supports .read(), so that's obviously
not the whole solution.

What were the values of 'action' and 'data' when the call was
made?
