urllib2.build_opener happily accepts and ignores a FileCookieJar. I had a bug in my code which looked like
urllib2.build_opener(func_returning_cookie_jar()) which should have been urllib2.build_opener(HTTPCookieProcessor(func_returning_cookie_jar()) The problem is that the code ran happily without actually sending the cookie, the CookieJar was just ignored. I think that build_opener should throw an exception when add_handler doesn't actually add. Is this worth filing a bug for, or is it acceptable behavior? -- http://mail.python.org/mailman/listinfo/python-list
