Questions regarding `parse_url`

[ltrk2]

Currently, parse_url doesn't support cases such as these at all (ie. all fields come back empty):

• print parse_url("mailto:John.Doe@example.com");
• print parse_url("news:comp.infosystems.www.servers.unix");
• print parse_url("tel:+1-816-555-1212");
• print parse_url("urn:oasis:names:specification:docbook:dtd:xml:4.1.2");

I'd consider the following cases bugs:

• print parse_url("https://john.doe@www.example.com:123/forum/questions/?tag=networking&order=newest#top");
  Actual
  {"Scheme":"https","Host":"john.doe@www.example.com","Port":"123","Path":"/forum/questions/","Username":"","Password":"","Query Parameters":{"order":"newest","tag":"networking"},"Fragment":"top"}
  Expected
  {"Scheme":"https","Host":"www.example.com","Port":"123","Path":"/forum/questions/","Username":"john.doe","Password":"","Query Parameters":{"order":"newest","tag":"networking"},"Fragment":"top"}
• print parse_url("ldap://[2001:db8::7]/c=GB?objectClass?one");
  Actual
  {"Scheme":"ldap","Host":"[2001:db8:","Port":"7]","Path":"/c=GB","Username":"","Password":"","Query Parameters":{},"Fragment":""}
  Expected
  {"Scheme":"ldap","Host":"2001:db8::7","Port":"","Path":"/c=GB","Username":"","Password":"","Query Parameters":{"objectClass":"","one":""},"Fragment":""}

The examples above were taken from https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Example_URIs.

Is parse_url meant to be compliant with RFC 3986? If not, would it be possible to clarify what cases are meant to be supported?
