Please add the previous URI to a failing test somewhere.

[Anders Johnsen, 2014/02/24 12:44:33]

Done.

We need tests. Lots of tests.

Something like:

for (var fragment in ["", ,"#", "#f", "#fragment", "#l:?/"]) {
  for (var query in ["", "?", "?q", "?query", "?q:/"]) {
    for (var path in ["", "x", "x/y", "x/y/", "x:y"]) {
      for (var user in ["", "x", "xxx", "x:4", "xxx:444", "x:4:x"] {
        for (var host in ["", "h", "hhh", "h:4", "hhh:444",
                          "[1.2.3.4]","<some ipv6addresses>"]) {
          var auth = host;
          if (user.isNotEmpty) auth = "$user@$auth";
          if (auth.isNotEmpty) auth = "//$auth";
          check("scheme:$auth/$path$query$fragment");
        }
      }         
    }
  }

and something similar for non-scheme URIs, where I believe the rules are
slightly different.

Done.
