Bug report

Bug description:

URLs supplied tourllib.request.url2pathname() may include a non-empty authority (netloc), such as a hostname.

On Windows, these are correctly decoded (mostly):

>>>url2pathname('//localhost/c:/foo.txt')'C:\\foo.txt'# OK>>>url2pathname('//server/share')'\\\\server\\share'# OK

But on POSIX, any non-empty authority exceptlocalhost is preserved in the path:

>>>url2pathname('//myhostname/etc/hosts')'//myhostname/etc/hosts'# expected '/etc/hosts'>>>url2pathname('//server/share')'//server/share'# expected URLError ('server' is not local)

PerRFC 8089 this isn't correct.

CPython versions tested on:

CPython main branch

Operating systems tested on:
