Better messaging on incorrect username or password

[Fuchida]

This is what you get if you supply incorrect username or password
when uploading to pypi.

requests.exceptions.HTTPError: 401 Client Error: 
You must be identified to edit package information for url: https://pypi.python.org/pypi

Is it possible to have flit state that the provided username and password is
incorrect ?

In any case thank you for making Flit, it's been the best experience in uploading to Pypi
and sharing my code with others 👍

It's definitely possible to catch that exception and give a different message. I don't know if code 401 comes up in any other situations, though. Can you try uploading to a package that you don't have access to, and check what error number it uses? And also try with the new upload URL (https://upload.pypi.org/legacy/) to check that it behaves the same?

In any case thank you for making Flit, it's been the best experience in uploading to Pypi

:-) Thanks, I'm glad it's useful!

[Fuchida]

How do you upload to the new upload URL (https://upload.pypi.org/legacy/) 😕
Did a quick look at the docs but no luck

[Carreau]

You can change your .pypirc like so:

$ cat ~/.pypirc | grep -v pass
[distutils]
index-servers =
    pypi
    testpypi
    localpypi

[pypi]
repository:https://upload.pypi.io/legacy/
username: xxx
password: yyy

[testpypi]
repository = https://testpypi.python.org/pypi
username: xxx
password: yyy

[localpypi]
repository:http://localhost:8000/pypi
username: xxx

Here i'm also setting multiple remotes.

OK, it looks like we can assume that 401 means you got your username/password wrong.
