From bc1c9c0e674bdd293c29ae84365915848ed01d7a Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 13 Oct 2017 13:45:40 +0900 Subject: branch: split validate_new_branchname() into two Checking if a proposed name is appropriate for a branch is strictly a subset of checking if we want to allow creating or updating a branch with such a name. The mysterious sounding 'attr_only' parameter to validate_new_branchname() is used to switch the function between these two roles. Instead, split the function into two, and adjust the callers. A new helper validate_branchname() only checks the name and reports if the branch already exists. This loses one NEEDSWORK from the branch API.
