bundle install --local in test tries to contact remote

[marcotc]

While implementing #184, I noticed that appraisal tests (invoking rake in this repository) were failing.

At first they were failing with the issue addressed by #184, but after fixing that there's still one more test failing:

[DEPRECATED] The --binstubs option will be removed in favor of `bundle binstubs --all`
Could not reach host other-rubygems.org. Check your network connection and try
again.

This errors happens only with newer versions of bundler.

After bisecting the bundler changes, I found that rubygems/rubygems@d8b59a1 introduces the behaviour makes this test fail (which was released with bundler 2.2.14).

It seems like bundle install --local wants to contact other-rubygems.org, which doesn't seem right.
When using a version of bundler from before rubygems/rubygems@d8b59a1, it does not try to contact the remote.

I wasn't able to decipher what part of rubygems/rubygems@d8b59a1 is the culprit, or if the issue is in appraisal or in bundler itself. I'm opening the issue here as this is manifested in one of the tests in the repository.

In your local setup, have you switched git to use main in the init.defaultBranch configuration?

If I restore this value to master, the tests pass but with main two are failing. Could you try the same and see if you get the same outcome?

[nickcharlton]

Oh! I think I understand the problem properly now.

I was previously running 2.2.4, and seeing failures around this test, too, which confused me. I upgraded bundler to 2.2.24 which resolved the Git problem I mentioned previously (there's a small change we can make here to avoid a lot of hint: ... warnings).

In the test, we're just running bundle install --local by shelling out to it, so I think this is a problem upstream. I'll open an issue there as I can't see anything wrong with our setup here.

This is now fixed upstream I think!

[nickcharlton]

Wonderful! Thank you, @deivid-rodriguez.

@marcotc, could you try this again at some point and see if your problem is resolved?
