To check availability, refs_verify_refname_available() will run refs_read_raw_ref() on each prefix, leading to a read() from .git/refs (which is a directory). It would probably be more robust to re-issue the lstat() as a normal stat(), in which case, we would fall back to the directory case, but for now let's just test for the existing behavior as-is. This test covers a regression in a commit that only ever made it to "next", see [1]. 1. http://lore.kernel.org/git/pull.1068.git.git.1629203489546.gitgitgadget@gmail.com Signed-off-by: Han-Wen Nienhuys Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano --- diff --git a/t/t3200-branch.sh b/t/t3200-branch.sh index e575ffb4ff..53e0d094bb 100755 --- a/t/t3200-branch.sh +++ b/t/t3200-branch.sh @@ -731,6 +731,28 @@ test_expect_success SYMLINKS 'git branch -m u v should fail when the reflog for test_must_fail git branch -m u v ' +test_expect_success SYMLINKS 'git branch -m with symlinked .git/refs' ' + test_when_finished "rm -rf subdir" && + git init --bare subdir && + + rm -rfv subdir/refs subdir/objects subdir/packed-refs && + ln -s ../.git/refs subdir/refs && + ln -s ../.git/objects subdir/objects && + ln -s ../.git/packed-refs subdir/packed-refs && + + git -C subdir rev-parse --absolute-git-dir >subdir.dir && + git rev-parse --absolute-git-dir >our.dir && + ! test_cmp subdir.dir our.dir && + + git -C subdir log && + git -C subdir branch rename-src && + git rev-parse rename-src >expect && + git -C subdir branch -m rename-src rename-dest && + git rev-parse rename-dest >actual && + test_cmp expect actual && + git branch -D rename-dest +' + test_expect_success 'test tracking setup via --track' ' git config remote.local.url . && git config remote.local.fetch refs/heads/*:refs/remotes/local/* &&
