From 17eff96b83be5c4c25e33a40e632d1b55c506d33 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Mon, 24 Apr 2017 17:01:22 +0700 Subject: refs: introduce get_worktree_ref_store() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit files-backend at this point is still aware of the per-repo/worktree separation in refs, so it can handle a linked worktree. Some refs operations are known not working when current files-backend is used in a linked worktree (e.g. reflog). Tests will be written when refs_* functions start to be called with worktree backend to verify that they work as expected. Note: accessing a worktree of a submodule remains unaddressed. Perhaps after get_worktrees() can access submodule (or rather a new function get_submodule_worktrees(), that lists worktrees of a submodule), we can update this function to work with submodules as well.
