Are there other matching refs between one and two that are subject to the push operation here, or is the 'master' the only thing that exists? > + # If master is in negative refspec, then the command will not attempt > + # to push and succeed. > + # We do not need test_config here as we are updating remote.one.push > + # again.

Is there other branches involved, or this is essentially a no-op as there is only 'master' branch involved in the operation? > +' > + > +test_expect_success "push with matching +: and negative refspec" ' > + test_config -C two remote.one.push +: && > + # Fails to push master w/ tip behind counterpart > + test_must_fail git -C two push one && Assuming that the successful case from the previous test was a no-op, we start from the same condition from the previous one. THe only difference is that the matching push is now configured to force. So, how would this one fail, exactly? Aren't we forcing? Shouldn't we succeed in such a case? I think the test still fails to push but for a different reason. It is not because the tip being pushed is not ahead of the counterpart at the receiving repository. +: (i.e. force-push matching refs) takes care of the "must fast-forward" requirement that causes the previous one to fail. It is because the receiving repository is not a bare repository, and the push attempts to update its current branch. It cannot be forced with + prefix, and that is why it fails. So, the comment above is wrong.

Let me see if I can come up with a suggestion to get us closer to that goal. ... goes and hacks ... Perhaps squash the following into this step?
