Summary: Python's urllib expects a fully qualified URL in HTTP_PROXY (like
"http://proxy:8080/"). Many applications allow short forms in HTTP_PROXY
(like "proxy:8080"). If HTTP_PROXY is set to a short form, urllib.py will
fail with an uncomprehensible error message.

Long form:

Francesco Potorti` <F.Potorti@cnuce.cnr.it> says (in the Debian bug report
http://www.debian.org/Bugs/db/42/42318.html):

"when setting a proxy variable that is not parsed by urllib, urllib does
not print a comprehensible error message."

An example:

Short form HTTP_PROXY:

master% HTTP_PROXY="proxy.cnr.it:8081" \
python -c 'import urllib; print
urllib.urlretrieve("http://www.olemiss.edu/")'
Traceback (innermost last):
File "<string>", line 1, in ?
File "/usr/lib/python1.5/urllib.py", line 69, in urlretrieve
return _urlopener.retrieve(url)
File "/usr/lib/python1.5/urllib.py", line 186, in retrieve
fp = self.open(url)
File "/usr/lib/python1.5/urllib.py", line 154, in open
return self.open_unknown(fullurl)
File "/usr/lib/python1.5/urllib.py", line 168, in open_unknown
raise IOError, ('url error', 'unknown url type', type)
IOError: ('url error', 'unknown url type', 'http')

Fully qualified URL in HTTP_PROXY:

master% HTTP_PROXY="http://proxy.cnr.it:8081" \
python -c 'import urllib; print
urllib.urlretrieve("http://www.olemiss.edu/")'

Please do triage on this bug.

Assigned to Barry because I think of him as being the Potato Man.

[jhylton]

The immediate fix for this bug report is to raise a more explanatory error message:
IOError: [Errno url error] invalid proxy for http: 'localhost:3128'

In the long term, we may want to support the requested feature.
Added to PEP-42.

[shinnosuke]

I found a solution of the same errors from Windows, and my solution was
removed the double quote at HTTP_PROXY settings.
