[issue18543] urllib.parse.urlopen shouldn't ignore installed opener when called with any ca* argument

[Moritz Sichert]

New submission from Moritz Sichert:

If you pass any of cafile, capath or cadefault to urllib.parse.urlopen it creates a new opener that contains the HTTPSHandler that was according to the ca* arguments. It then uses this new opener to execute the request.
If you installed a custom opener with urllib.parse.install_opener it won't be used.

urlopen should either add a HTTPSHandler to the installed opener or not accept any Handler specific arguments at all.
