From d026a25657cbe15ceb6bcb5d5047a36a0a70b33e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Mon, 24 Apr 2017 17:01:24 +0700 Subject: [PATCH] refs: kill set_worktree_head_symref() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 70999e9cec (branch -m: update all per-worktree HEADs - 2016-03-27) added this function in order to update HEADs of all relevant worktrees, when a branch is renamed. It, as a public ref api, kind of breaks abstraction when it uses internal functions of files backend. With the introduction of refs_create_symref(), we can move back pretty close to the code before 70999e9cec, where create_symref() was used for updating HEAD.
