Subject: [PATCH v3 2/4] refs: introduce get_worktree_ref_store()
Date: Sat, 18 Mar 2017 17:02:04 +0700 [thread overview]
Message-ID: <20170318100206.5980-3-pclouds@gmail.com> (raw)
In-Reply-To: <20170318100206.5980-1-pclouds@gmail.com>
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.
