chore: refactor replace urlparse with urlsplit and use urllib_ Python docs recommend use of urlsplit() rather than urlparse(). urlsplit() is a little faster and doesn't try to split the path into path and params using the rules from an obsolete RFC. actions.py, demo.py, rest.py, client.py Replace urlparse() with urlsplit() actions.py urlsplit() produces a named tuple with one fewer elements (no .param). So fixup calls to urlunparse() so they have the proper number of elements in the tuple. also merge url filtering for param and path. demo.py, rest.py: Replace imports from urlparse/urllib.parse with roundup.anypy.urllib_ so we use the same interface throughout the code base. test/test_cgi.py: Since actions.py filtering for invali urls not split by path/param, fix tests for improperly quoted url's.
