Subject: [PATCH v2 5/9] checkout-index: add --ignore-skip-worktree-bits option
Date: Tue, 11 Jan 2022 18:05:02 +0000 [thread overview]
Message-ID: <601888606d1cf7d7752844dbdbc7fac20d4be8c4.1641924306.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1109.v2.git.1641924306.gitgitgadget@gmail.com>
From: Victoria Dye <vdye@github.com>
Update `checkout-index` to no longer refresh files that have the
`skip-worktree` bit set, exiting with an error if `skip-worktree` filenames
are directly provided to `checkout-index`. The newly-added
`--ignore-skip-worktree-bits` option provides a mechanism to replicate the
old behavior, checking out *all* files specified (even those with
`skip-worktree` enabled).
The ability to toggle whether files should be checked-out based on
`skip-worktree` already exists in `git checkout` and `git restore` (both of
which have an `--ignore-skip-worktree-bits` option). The change to, by
default, ignore `skip-worktree` files is especially helpful for
sparse-checkout; it prevents inadvertent creation of files outside the
sparse definition on disk and eliminates the need to expand a sparse index
when using the `--all` option.
Internal usage of `checkout-index` in `git stash` and `git filter-branch` do
not make explicit use of files with `skip-worktree` enabled, so
`--ignore-skip-worktree-bits` is not added to them.
