From 70999e9ceca47e03b8900bfb310b2f804125811e Mon Sep 17 00:00:00 2001 From: Kazuki Yamaguchi Date: Sun, 27 Mar 2016 23:37:14 +0900 Subject: branch -m: update all per-worktree HEADs When renaming a branch, currently only the HEAD of current working tree is updated, but it must update HEADs of all working trees which point at the old branch. This is the current behavior, /path/to/wt's HEAD is not updated: % git worktree list /path/to 2c3c5f2 [master] /path/to/wt 2c3c5f2 [oldname] % git branch -m master master2 % git worktree list /path/to 2c3c5f2 [master2] /path/to/wt 2c3c5f2 [oldname] % git branch -m oldname newname % git worktree list /path/to 2c3c5f2 [master2] /path/to/wt 0000000 [oldname] This patch fixes this issue by updating all relevant worktree HEADs when renaming a branch.
