urllib.request.pathname2url() and url2pathname() remove slashes on Windows #126212
Description
Bug report
Bug description:
urllib.request.pathname2url() unexpectedly removes doubled and trailing slashes, but only on Windows, and only for DOS device paths (not UNC paths):
>>> from urllib.request import pathname2url, url2pathname
>>> pathname2url('C:\\')
'///C:' # This is *not* the same path!
>>> pathname2url('C:\\foo\\')
'///C:/foo'
>>> pathname2url('C:\\foo\\\\bar')
'///C:/foo/bar'url2pathname() does almost the same thing, except that it specially preserves a slash immediately after a DOS drive (but not elsewhere):
>>> url2pathname('///c:/')
'C:\\' # OK
>>> url2pathname('///c:/foo/')
'C:\\foo'
>>> url2pathname('///c:/foo//bar')
'C:\\foo\\bar'This behaviour makes no sense and has no equivalent on POSIX, where all slashes are preserved.
