Subject: [PATCH v2 5/7] refresh_index(): add REFRESH_DONT_MARK_SPARSE_MATCHES flag
Date: Wed, 24 Feb 2021 01:05:10 -0300
Message-ID: <d65b214dd1d83a2e8710a9bbf98477c1929f0d5e.1614138107.git.matheus.bernardino@usp.br> (raw)
In-Reply-To: <cover.1614138107.git.matheus.bernardino@usp.br>

refresh_index() optionally takes a seen[] array to mark the pathspec
items that had matches in the index. This is used by `git add --refresh`
to find out if there were any pathspec without matches, and display an
error accordingly.

In the following patch, `git add` will also learn to warn about
pathspecs that only match sparse entries (which are not updated). But
for that, we will need a seen[] array marked exclusively with matches
from dense entries. To avoid having to call ce_path_match() again for
these entries after refresh_index() returns, add a flag that implements
this restriction inside the function itself.

Note that refresh_index() does not update sparse entries, regardless of
passing the flag or not. The flag only controls whether matches with
these entries should appear in the seen[] array.

While we are here, also realign the REFRESH_* flags and convert the hex
values to the more natural bit shift format, which makes it easier to
spot holes.
