Subject: [RFC PATCH 3/3] grep: add option to ignore sparsity patterns
Date: Tue, 24 Mar 2020 03:13:44 -0300 [thread overview]
Message-ID: <a76242ecfa69cf29995bd859305dc2ab1bc1a221.1585027716.git.matheus.bernardino@usp.br> (raw)
In-Reply-To: <cover.1585027716.git.matheus.bernardino@usp.br>
In the last commit, git-grep learned to honor sparsity patterns. For
some use cases, however, it may be desirable to search outside the
sparse checkout. So add the '--ignore-sparsity' option, which restores
the old behavior. Also add the grep.ignoreSparsity configuration, to
allow setting this behavior by default.
Signed-off-by: Matheus Tavares <matheus.bernardino@usp.br>

Note: I still have to make --ignore-sparsity be able to work together
with --untracked. Unfortunatelly, this won't be as simple because the
codeflow taken by --untracked goes to grep_directory() which just
iterates the working tree, without looking the index entries. So I will
have to either: make --untracked use grep_cache(), and grep the
untracked files later; or try matching the working tree paths against
the sparsity patterns, without looking for the skip_worktree bit in
the index (as I mentioned in the previous patch's comments). Any
preferences regarding these two approaches? (or other suggestions?)
