urllib and urllib2, with proxies

hello all,

I just maybe hit a bug in both urllib and urllib2, actually urllib
doesn't support proxy authentication, and if you setup the http_proxy
env var to http_proxy=http ://user:passwd@hos t:port/ and
https_proxy=$ht tp_proxy i get a traceback :

Traceback (most recent call last):
File "test_urllib.py ", line 2, in ?
urllib.urlopen( "https://sf.net/")
File "/usr/lib/python2.4/urllib.py", line 82, in urlopen
return opener.open(url )
File "/usr/lib/python2.4/urllib.py", line 190, in open
return getattr(self, name)(url)
File "/usr/lib/python2.4/urllib.py", line 313, in open_http
File "/usr/lib/python2.4/httplib.py", line 798, in endheaders
self._send_outp ut()
File "/usr/lib/python2.4/httplib.py", line 679, in _send_output
File "/usr/lib/python2.4/httplib.py", line 646, in send
File "/usr/lib/python2.4/httplib.py", line 614, in connect
socket.SOCK_STR EAM):
IOError: [Errno socket error] (-2, 'Name or service not known')
now with urllib2, it goes beyond that and connect and authenticate to
the proxy, however, instead of using CONNECT with https, it simply does
a GET, which result in a error 501 with a squid proxy:

Traceback (most recent call last):
File "test_urllib.py ", line 2, in ?

response = meth(req, response)

result = func(*args)

raise HTTPError(req.g et_full_url(), code, msg, hdrs, fp)

this is with python-2.4.3

thank you for your help

I think I've found a deficiency in the design of urllib related to https. In order to complete an https connection, it appears that URLOpener and hence FancyURLOpener require the key and cert files. Or at least, it's not clear from the description of socket.ssl what it does if they're omitted. However, urlopen has no way to specify such things. Nor should it - for typical uses, a person simply trying to retrieve data from an ssl site...

Hello, I have defined a function to set an opener for urllib2, this opener defines any proxy and http authentication that is required. If the proxy has authencation itself and requests an authenticated file I get a HTTP status code of 401 (Unauthorized access of the file being requested) I do see in the headers the Proxy-authorization and the Authorization headers being sent for the request.

I thought I had all the timeout problems with urllib worked around, but no. socket.setdefaulttimeout is useful, but not always effective. I'm setting that to 15 seconds. If the host end won't open the connection within 15 seconds, urllib times out. But if the host end opens the connection, then never sends anything, urllib waits for many minutes before timing out. Any idea how to deal with this? And don't just say "use urllib2"...

Hi, There is an Open Tracker item against urllib2 library python.org/sf/735515 which states that. urllib / urllib2 should cache the results of 301 (permanent) redirections. This shouldn't break anything, since it's just an internal optimisation from one point of view -- but it's also what the RFC (2616, section 10.3.2, first para) says SHOULD happen. I am trying to understand, what does it mean. Should the original url be avaiable to...
