CI hasn't triggered for this PR for some reason. Huh.

That should help?

I've just pushed a new commit and the CIs are getting the hook now. I've been spending so much time on this so I guess I'll switch back to implementing the integration of the utilities. This is wearing me out and being stressed about not getting things done makes me even less productive 😄

The part I'm particularly stuck at is (I think, regarding the error log) how to provide the response for HEAD requests and probably the mock server doesn't handle multiple requests: 7df1646. Mainly because I couldn't found the part of tutorial referring to what pip is doing currently.

HEAD requests

I think we should do that in an follow up PR - this change as is is pretty atomic and does one thing (which makes it easier to review, discuss etc).

I'm happy to reset to da574fb and revisit the mock server supporting range request thing when I'm emotionally recovered from this and/or these tests show to have too much negative effect on the whole suit. I also figure that it's not likely that we should mock a server with all the dependencies for the integration tests.

@pradyunsg, is there anything you'd like to iterate on before merging?

Nope -- LGTM.
