[PATCH 02/15] t5516: demonstrate push with "./"-prefixed source

From: Jon Simons <jon@jonsimons.org>
Date: Oct 9, 2026, 19:29 UTC
Message-ID: <20261009192953.81794-3-jon@jonsimons.org>
In-Reply-To: <20261009192953.81794-1-jon@jonsimons.org>

'git push <repo> ./refs/heads/main:refs/heads/frotz' succeeds today and pushes refs/heads/main, although "./refs/heads/main" is not a valid refname. count_refspec_match() compares the source to each local ref using refname_match(), which formats its given name with mkpath(), whose cleanup_path() strips leading "./".

Add a test_expect_failure asserting that such a source is rejected with "src refspec ./refs/heads/main does not match any". An upcoming commit stops using mkpath() in refname_match(), at which point the test is toggled to test_expect_success.
