The implementation of the helper in this iteration does look cleaner than in the previous iteration. But these many references to "repo/" and "-C repo" we see below makes me wonder why we do not put the whole thing inside the subshell we started earlier. i.e. git init repo && ( cd repo && setup_stash_test && echo 9 >file && old=$(git rev-parse stash@{0}) && git stash && new=$(git rev-parse stash@{0}) && ... test_cmp expect actual ) > + echo 9 >repo/file && > + > + old_oid="$(git -C repo rev-parse stash@{0})" && > + git -C repo stash && > + new_oid="$(git -C repo rev-parse stash@{0})" && > + > + cat >expect <<-EOF && > + $(test_oid zero) $old_oid > + $old_oid $new_oid > + EOF > + cut -d" " -f1-2 repo/.git/logs/refs/stash >actual && > + test_cmp expect actual && > + > + git -C repo stash drop stash@{1} && > + cut -d" " -f1-2 repo/.git/logs/refs/stash >actual && > + cat >expect <<-EOF && > + $(test_oid zero) $new_oid > + EOF > + test_cmp expect actual > +' > + > test_expect_success 'stash pop' ' > git reset --hard && > git stash pop &&

Maybe I'm missing what this test is actually needs to do. I thought it just needed to check that the deleted stash is removed from the reflog and the others are unchanged. You're right that it wont show the LHS and if that is important then you need to read the log file directly.

I thought it just needed to check that the deleted stash is removed from the reflog and the others are unchanged. You're right that it wont show the LHS and if that is important then you need to read the log file directly. We had discussed this briefly in [1], but the --rewrite option for reflog delete will rewrite the LHS, which is not visible to normal ref API users. So the only way to test that this happened is to reach inside of the file. 1. https://lore.kernel.org/git/xmqqczjdp2g8.fsf@gitster.g/ > > Best Wishes > > Phillip thanks, John > > >>>>> + echo 9 >repo/file && >>>>> + >>>>> + old_oid="$(git -C repo rev-parse stash@{0})" && >>>>> + git -C repo stash && >>>>> + new_oid="$(git -C repo rev-parse stash@{0})" && >>>>> + >>>>> + cat >expect <<-EOF && >>>>> + $(test_oid zero) $old_oid >>>>> + $old_oid $new_oid >>>>> + EOF >>>>> + cut -d" " -f1-2 repo/.git/logs/refs/stash >actual && >>>>> + test_cmp expect actual && >>>>> + >>>>> + git -C repo stash drop stash@{1} && >>>>> + cut -d" " -f1-2 repo/.git/logs/refs/stash >actual && >>>>> + cat >expect <<-EOF && >>>>> + $(test_oid zero) $new_oid >>>>> + EOF >>>>> + test_cmp expect actual >>>>> +' >>>>> + >>>>> test_expect_success 'stash pop' ' >>>>> git reset --hard && >>>>> git stash pop && >>
