[PATCH v2 0/7] add/rm: honor sparse checkout and warn on sparse paths

[Matheus Tavares <matheus.bernardino@usp.br>]

Make `rm` honor sparse checkouts, and make both `rm` and `add` warn
about pathspecs that only match sparse entries.

This is now based on mt/add-chmod-fixes.

Main changes since RFC:

Ejected "add --chmod: don't update index when --dry-run is used", which
is now part of mt/add-chmod-fixes.

Patch 2:
- Fixed style problems.
- Fixed comment on setup_sparse_entry() about argument being passed to
  printf.
- Standardized on 'sparse entries' on test names.
- Added test for 'git add .', and set up a .gitignore to run this and
  the 'git add -A' test, to avoid smudging the index.
- Added test for --dry-run.
- Modified `git add --refresh` test to use `git ls-files --debug`
  instead of diff-files.

Added patch 5

Patch 6:
- Improved commit message.
- Used the flag added in patch 5 instead of directly changing
  refresh_index(), so that new users of seen[] can still have the
  complete match array.
- Added test for --ignore-missing.
- Added test where the pathspec matches both sparse and dense entries.
- Changed 'git add .' behavior where . only contains sparse entries. [1]

Patch 7:
- Moved rm-sparse-checkout tests to their own file. They need a repo
  with a different setup than the one t3600 has, and the subshells (or
  git -C ...) were making the tests too hard to read.
- Added tests for -f, --dry-run and --ignore-unmatch.
- Added test where the pathspec matches both sparse and dense entries.
- Also test if the index entry is really not removed (besides testing
  `git rm` exit code and stderr).
- Passed "a" instead of "/a" to git sparse-checkout to avoid MSYS path
  conversions on Windows that would make some of the new tests fail.

[1]: Although the sparse entries warning is based on the ignored files
     warning, they have some differences. One of them is that running
     'git add dir' where 'dir/somefile' is ignored does not trigger a
     warning, whereas if 'somefile' is a sparse entry, we warn. In
     this sense, I think it's more coherent to also warn on 'git add .'
     when . only has sparse entries. This is also consistent with what
     'git rm -r .' does in the same scenario, after this series.

Matheus Tavares (7):
  add: include magic part of pathspec on --refresh error
  t3705: add tests for `git add` in sparse checkouts
  add: make --chmod and --renormalize honor sparse checkouts
  pathspec: allow to ignore SKIP_WORKTREE entries on index matching
  refresh_index(): add REFRESH_DONT_MARK_SPARSE_MATCHES flag
  add: warn when pathspec only matches SKIP_WORKTREE entries
  rm: honor sparse checkout patterns

         add: warn when pathspec only matches SKIP_WORKTREE entries
     
         `git add` already refrains from updating SKIP_WORKTREE entries, but it
    -    silently succeeds when a pathspec only matches these entries. Instead,
    -    let's warn the user and display a hint on how to update these entries.
    +    silently exits with zero code when a pathspec only matches these
    +    entries. Instead, let's warn the user and display a hint on how to
    +    update these entries.
     
         Note that the warning is only shown if the pathspec matches no untracked
         paths in the working tree and only matches index entries with the
    -    SKIP_WORKTREE bit set. Performance-wise, this patch doesn't change the
    -    number of ce_path_match() calls in the worst case scenario (because we
    -    still need to check the sparse entries for the warning). But in the
    -    general case, it avoids unnecessarily calling this function for each
    -    SKIP_WORKTREE entry.
    -
    -    A warning message 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 matching pathspecs, as the matched files will have
    -    already been added.
    -
    -    Note: refresh_index() was changed to only mark matches with
    -    no-SKIP-WORKTREE entries in the `seen` output parameter. This is exactly
    -    the behavior we want for `add`, and only `add` calls this function with
    -    a non-NULL `seen` pointer. So the change brings no side effect on
    -    other callers.

         rules, but `git rm` doesn't follow the same restrictions. This is
         somewhat counter-intuitive and inconsistent. So make `rm` honor the
         sparse checkout and advise on how to remove SKIP_WORKTREE entries, just
    -    like `add` does. Also add a few tests for the new behavior.
