So the failures are the following:

We fixed the AttributeError, but I don't know why the other happens.

Note: using localhost instead of 127.0.0.1 doesn't seem the right solution as we also have tests with 127.0.0.1 elsewhere.

However, maybe we can just ignore the bind itself and check for the "best" address (which is chosen by http.server via _get_best_family).

[picnixz]

I've committed directly to your branch as the tier-1 bot is failing (making it hard to fix another issue I introduced in a subsequent commit, not your fault!)

Ok, so the tests now hang on non-Linux bots. I'll stop working on this branch and will come back on my linux in a few hours.

[picnixz]

So localhost doesn't work and 127.0.0.1 doesn't work for some build bots. I think we'll just leave it to the script the responsibility to start the server and we'll deduce the bind address from the output.

[picnixz]

Ok, so now, the tests entirely hang for some obscure reasons. I'll open a new PR instead, sorry for messing up your branch though (but thank you for your quick response time).
