I attempted to connect to a site using urllib2 and digest authentication and it raised an HTTPError (due to an incorrect username and password, which is expected).  I attempted to run the info() method of the HTTPError to get more information, but it failed with an AttributeError (this is the bug).

$ ./reproducer.py 
Traceback (most recent call last):
  File "./reproducer.py", line 16, in <module>
    print e.info()
  File "/usr/lib/python2.6/urllib.py", line 987, in info
    return self.headers
AttributeError: 'HTTPError' object has no attribute 'headers'

$ python --version
Python 2.6.6

Python 2.6 is now in security-fix-only mode.

Okay, this is funny. first info is invoking addinfourl of urllib, which would return headers. But in urllib2, the headers are self.hdrs

I would side with the documentation that info is advertised method for HTTPError object. In 2.7,  I guess just docs could be improved. This problem would be the present in 3.x.

Even though 2.x is in security fix mode, this can be fixed by a overriding the base class's info method in the HTTPError class and returning the .hdrs attribute instead of .headers.
