Fix contributed by Jeffrey C. Ollie.
I haven't tested the fix because the situation is non-trivial to
reproduce.
The basic solution is to get rid of the __current_realm attribute of
authentication handlers. Instead, prevent infinite retries by
checking for the presence of an Authenticate: header in the request
object that exactly matches the Authenticate: header that would be
added.
The problem prevent authentication from working correctly in the
presence of retries.
Ollie mentioned that digest authentication has the same problem and I
applied the same solution there.
When checking for strings use,
! if isinstance(uri, (types.StringType, types.UnicodeType)):
Also get rid of some dodgy code that tried to guess whether attributes
were callable or not.
Modify rfc822.formatdate() to always generate English names,
regardless of locale. This is required by RFC 1123.
In open_local_file() of urllib and urllib2, use new formatdate() from
rfc822.
Also fix another bug caught by pychecker-- HTTPError() raised when
redirect limit exceed did not pass an fp object. Had to change method
to keep fp object around until it's certain that the error won't be
raised.
Remove useless line in do_proxy().
- don't close the fp, since that appears to also close the socket
- join the original url with the redirect reponse to deal with
relative redirect URL
wrap two socket ops in try/except to turn them into URLErrors, so that
client code need only catch one exception.
in HTTPError.__del__ only close fp if fp is not None
style changes:
- use f(*args) instead of apply(f, args)
- use __super_init instead of super.__init__(self, ...)
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").
There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)
The attached patches update the standard library so that all modules
have docstrings beginning with one-line summaries.
A new docstring was added to formatter. The docstring for os.py
was updated to mention nt, os2, ce in addition to posix, dos, mac.
