commit ebb826f4a15c90d480bb5384facc9d05e13505ab
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Wed Mar 24 10:19:21 2021 -0400

    Add an extra prop330 test, and clarifying comments.
    
    This test makes sure that we reject "upload=" URLs with bad IP
    addresses.
    
    Also, add a warning when we can't parse the address.
