Inbcfc82bd48
(branch: description for non-existent branch errors, 2022-10-08) we checked the HEAD in the current worktree to detect if the branch to operate with is an orphan branch, so as to avoid the confusing error: "No branch named...". If we are asked to operate with an orphan branch in a different working tree than the current one, we need to check the HEAD in that different working tree. Let's extend the check we did inbcfc82bd48
, to check the HEADs in all worktrees linked to the current repository, using the helper introduced in31ad6b61bd
(branch: add branch_checked_out() helper, 2022-06-15). The helper, branch_checked_out(), does its work obtaining internally a list of worktrees linked to the current repository. Obtaining that list is not a lightweight work because it implies disk access. In copy_or_rename_branch() we already have a list of worktrees. Let's use that already obtained list, and avoid using here the helper. Signed-off-by: Rubén Justo <rjusto@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
