From 0a101676e58481f134353ee1ff3ccee6cbbbb74b Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Thu, 1 Sep 2022 15:42:19 +0000 Subject: add -p: ignore dirty submodules Thanks to always running `diff-index` and `diff-files` with the `--numstat` option (the latter with `--ignore-submodules=dirty`) before even generating any real diff to parse, the Perl version of `git add -p` simply ignored dirty submodules and does not even offer them up for staging. However, the built-in variant did not use that flag because it tries to run only one `diff` command, skipping the unneeded `diff-index`/`diff-files` invocation of the Perl variant and therefore only faithfully recapitulates what the Perl code does once it _does_ generate and parse the real diff. This causes a problem when running the built-in `add -p` with `diff-so-fancy` because that diff colorizer always inserts an empty line before the diff header to ensure that it produces 4 lines as expected by `git add -p` (the equivalent of the non-colorized `diff`, `index`, `---` and `+++` lines). But `git diff-files` does not produce any `index` line for dirty submodules. The underlying problem is not even the discrepancy in lines, but that `git add -p` presents diffs for dirty submodules: there is nothing that _can_ be staged for those. Let's fix that bug, and teach the built-in `add -p` to ignore dirty submodules, too. This _incidentally_ also fixes the `diff-so-fancy` problem ;-) Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano --- add-patch.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'add-patch.c') diff --git a/add-patch.c b/add-patch.c index a6bd150de5..a659653286 100644 --- a/add-patch.c +++ b/add-patch.c @@ -419,7 +419,8 @@ static int parse_diff(struct add_p_state *s, const struct pathspec *ps) } color_arg_index = args.nr; /* Use `--no-color` explicitly, just in case `diff.color = always`. */ - strvec_pushl(&args, "--no-color", "-p", "--", NULL); + strvec_pushl(&args, "--no-color", "--ignore-submodules=dirty", "-p", + "--", NULL); for (i = 0; i < ps->nr; i++) strvec_push(&args, ps->items[i].original); -- cgit v1.3
