Subject: [PATCH v4 6/7] add: warn when asked to update SKIP_WORKTREE entries
Date: Thu, 8 Apr 2021 17:41:27 -0300 [thread overview]
Message-ID: <da9cd3e9f6c10e624e46774e8b19f3caaf1ef60f.1617914011.git.matheus.bernardino@usp.br> (raw)
In-Reply-To: <cover.1617914011.git.matheus.bernardino@usp.br>
`git add` already refrains from updating SKIP_WORKTREE entries, but it
silently exits with zero code when it is asked to do so. Instead, let's
warn the user and display a hint on how to update these entries.
Note that we only warn the user whey they give a pathspec item that
matches no eligible path for updating, but it does match one or more
SKIP_WORKTREE entries. A warning was chosen over erroring out right away
to reproduce the same behavior `add` already exhibits with ignored
files. This also allow users to continue their workflow without having
to invoke `add` again with only the eligible paths (as those will have
already been added).
