[New-bugs-announce] [issue42215] urlparse with a Windows path returns the drive name as the scheme

[Rangel Reale]

New submission from Rangel Reale <rangelspam at gmail.com>:

Passing a Windows path to urllib.parse.urlparse, without file://, makes it detect the drive as the scheme even it having '\' after the ':', which makes it completelly wrong for a url.

Probably this function shouldn't be used with non-uri paths, but it shouldn't return a result that is so wrong as this. I think at least it should return the same input string if the url doesn't start with ://.

from urllib.parse import urlparse
urlparse('M:\\prog\\tests\\python\\json-ref-dict\\tests/schemas/master.yaml')

str(urlparse('M:\\prog\\tests\\python\\json-ref-dict\\tests/schemas/master.yaml'))
Out[4]: "ParseResult(scheme='m', netloc='', path='\\\\prog\\\\tests\\\\python\\\\json-ref-dict\\\\tests/schemas/master.yaml', params='', query='', fragment='')"
