[New-bugs-announce] [issue15769] urllib.request.urlopen with cafile or capath set overrides any previous Handlers

[Brian Turek]

New submission from Brian Turek:

Using the code snippet below:

cj = http.cookiejar.CookieJar()
opener = urllib.request.build_opener(urllib.request.HTTPCookieProcessor())
urllib.request.install_opener(opener)
request = urllib.request.Request(url, data, headers) # url is https://something
sock = urllib.request.urlopen(request, cafile = 'cacert.pem')

One would expect to establish a verified HTTPS connection to the host and the cookies stored in the cookie jar.  Unfortunately urllib.request.urlopen, when called with cafile or capath set, calls urllib.request.build_opener without HTTPCookieProcessor included in the chain.  This results in never being able to support cookies in a "verified" HTTPS connection.
