This should be closed: this issue was resolved by patch 852995.

Sorry, last comment not very useful.
I think this should be closed.
Two real problems:
1. urllib2.urlopen incorrectly raises OSError instead of
URLError. This is already detected by my unit tests (852995),
and I'll file a separate bug for this later (when/if 852995 is
resolved).
2. Would be nice if urllib2's functional tests used PyUnit (so it
is clear which tests are passing or failing), and worked on
Windows. Again, I'll submit a separate patch.
To the bug poster:
0. ftplib is not urllib2, please report bugs separately.
1. You're not invoking ftplib's test program correctly. It seems
to work, at least partially:
python ftplib.py ftp.python.org /pub/www.python.org/index.html
2. It seems you're using Windows, so you shouldn't expect
opening /etc/password to work (though the test shouldn't crash
as it does, of course, and it should work on Windows, and it
should give an indication of pass/fail).

It is broken. I'd like to know where functional tests officially
live before fixing it. I'll ask on python-dev...

This is a response to quiver.
Thanks for pointing out the correct usage of ftlib, I am
slowly sorting out how to use ftplib from a script.
Unfortunately my report did not make it clear that there is
a problem with the operation of the test function.
Usually, a test function gives some assurance that the main
code of the module is functional. In this case, the test fails.
That, I suggest, indicates a bug. The bug could be in test
function or the module being exercised.
You are probably right that a host needs to be specified. I
suggest that the test function should be responsible for this.
Incidentally, it would be very helpful to the potential user
if the documentation made the names and roles of the various
cmds's clearer.

For the first one, you need to specify a host to run the
test.
For expample,
>python ftplib.py ftp.python.org -l
This gives
drwxrwxr-x 5 webmaster webmaster 512 Jan 25
2003 pub
There is a usage on the test in the script:
'''Test program.
Usage: ftp [-d] [-r[file]] host [-l[dir]] [-d[dir]] [-p]
[file] ...'''
I think this is not a bug.
For the second one, catching OSError along with IOError
might be needed.
