New submission from Hans-Peter Jansen: During programming a function, that replaces a wget call, I noticed, that something is wrong with urllibs proxy handling.
I usually use the scheme "http_proxy= wget -N -nd URL" when I need to bypass the proxy. Hence I was pretty confused, that this doesn't work with python(3). Creating an empty ProxyHandler isn't the real Mc Coy either. Diving into the issue, I found getproxies_environment, but couldn't make much sense out of its behavior, up until I noticed, that my OS (openSUSE ) creates both variants of environment variables behind the scenes: uppercase and lowercase. Consequence: python3 needs the scheme "http_proxy= HTTP_PROXY= python3 ..." Since I, like everyone else, prefer gentle tones over the loud, and want to spare this surprise for others in the future, I propose the attached patch. Process environment variables in two passes, first uppercase, then lowercase, allowing an empty lowercase value to overrule any uppercase value. Please consider applying this. ---------- components: Extension Modules files: prioritize_lowercase_proxy_vars_in_urllib_request.diff keywords: patch messages: 263720 nosy: frispete priority: normal severity: normal status: open title: Prioritize lowercase proxy variables in urllib.request type: behavior versions: Python 3.5 Added file: http://bugs.python.org/file42516/prioritize_lowercase_proxy_vars_in_urllib_request.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26804> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
