pip install on a shared directory (windows)

Question

I've tried to create my own Pypi repository, respecting https://www.python.org/dev/peps/pep-0503/. My idea was to put it in a shared directory (I'm using Windows), say host1/my-pypi. I've generated the index.html needed:

(dir) host1\my-pypi
     -> (dir) toto
         (file) index.html
         (file) toto-1.0.0.whl
     -> (file) index.html

the index.html files look somehow normal (same as in the pep-503). I try, from another computer, say host2 that has access to this shared directory to install toto package using:

pip install --index-url file://host1/my-pipy toto

but it fails (when it tries to read the file with a OSError: [Errno 22] Invalid argument: '\\host1\my-pypi\').

First, has anyone tried (and solved) this before? (That's the easy solution :-) ).

Second, I've dug a little in the code of pip, and there are a couple of things that are unclear to me (if there's ever a pro in pip that can answer ;-) ).

index.py, method find_all_candidates: it automatically changes my url list from [file://host1/my-pypi/toto], so it seems that it never tries to read host1\my-pypi\index.html... weird?

index.py, method get_page: well point 1 is not blocking for me as it magically matches my architecture, but there's a weird condition:

# Tack index.html onto file:// URLs that point to directories
(scheme, netloc, path, params, query, fragment) = \
    urllib_parse.urlparse(url)
if (scheme == 'file' and
        os.path.isdir(urllib_request.url2pathname(path))):
    # add trailing slash if not present so urljoin doesn't trim
    # final segment
    if not url.endswith('/'):
        url += '/'
    url = urllib_parse.urljoin(url, 'index.html')
    logger.debug(' file: URL is directory, getting %s', url)
resp = session.get(
    url,
    headers={
        "Accept": "text/html",
        "Cache-Control": "max-age=600",
    },
)

well, as expected, we have:

scheme = 'file'
netloc = 'host1'
path = '/my-pypi/'

but the check condition os.path.isdir(urllib_request.url2pathname(path))) is obviously false as we've discarded the network location. Hence index.html is not appended to the path (that would've been correct otherwise), and hence the error while trying to read a file that does not exist.
