It is not specified above and I think anyone calling this would have to remove the prefix before they could use the value. I can see how it would be more ergonimic to just have the value without the "ref: " prefix. I kept it because that's how the refs are represented on disk and git-symbolic-ref prints them out with the "ref: " prefix. I don't have a strong preference, but I lean a bit towards keeping it consistent with the output of other commands. > > >> +test_expect_success '--symbolic-name with symbolic ref' ' >> + test_when_finished "git symbolic-ref -d refs/heads/SYMBOLIC_REF_A" && >> + commit_oid=$(git rev-parse refs/heads/$GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME) && >> + cat >expect <<-EOF && >> + $commit_oid refs/heads/SYMBOLIC_REF_A ref:refs/heads/$GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME >> + EOF >> + git symbolic-ref refs/heads/SYMBOLIC_REF_A refs/heads/$GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME && >> + git show-ref --symbolic-name SYMBOLIC_REF_A >actual && >> + test_cmp expect actual >> +' > > I think it would be nice to see a test along the lines of > > git symbolic-ref refs/symref-c refs/heads/master > git symbolic-ref refs/symref-b refs/symref-c && > git symbolic-ref refs/symref-a refs/symref-b && > git show-ref --symbolic-name refs/symref-a >actual && > cat >expect <<\EOF && > $(git show-ref -s --verify refs/heads/master) refs/heads/symref-a refs/heads/symref-b > EOF > test_cmp expect actual > > to show what this command is expected to return when there is a chain of symbolic references. good point, will add this in the next series. > > Best Wishes > > Phillip thanks for the review!
