Jessica McKellar added the comment: I confirm Barry's observation in msg94150 that if you set http_proxy (or any `*_proxy` environment variable), ProxyHandler does show up in build_opener().handlers. You can also add a ProxyHandler to build_opener through the public API as described in http://docs.python.org/dev/library/urllib.request.html#examples.
I've attached a patch that updates the urllib2 and urllib.request documentation to clarify the situation. The patch also adds a missing DataHandler to the enumerated default handlers in the urllib2 note on basic authentication. I built the documentation and inspected the generated HTML to confirm proper formatting. -- As a side note on what's going on with ProxyHandler's interaction with `if meth in ["redirect_request", "do_open", "proxy_open"]:`, since this was confusing to me until I dug into the source a bit: When you don't have any proxy environment variables set, ProxyHandler only has one <protocol>_<condition> method that might get the handler registered -- proxy_open -- which gets skipped because of the above blacklisted methods check. When a proxy environment variable is set, ProxyHandler grows a *_open method which does get it registered as a handler. ---------- keywords: +patch nosy: +jesstess versions: +Python 3.3, Python 3.4 -Python 2.6 Added file: http://bugs.python.org/file29817/issue7152.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7152> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
