`cargo publish` produces "X files in the working directory contain changes that were not yet committed into git" for .gitignored files

[Byron]

I see this regularly when publishing gitoxide crates and thought this was fixed with the switch to gitoxide, using cargo 1.92.0 (344c456 2025-10-21).

error: 4 files in the working directory contain changes that were not yet committed into git:

gix-dir/tests/fixtures/generated-do-not-edit/many/613585535-unix/slash-in-root-and-negated/.github/workflow.yml
gix-dir/tests/fixtures/generated-do-not-edit/many/613585535-unix/slash-in-subdir-and-negated/sub/.github/workflow.yml
gix-dir/tests/fixtures/generated-do-not-edit/many/613585535-unix/star-in-root-and-negated/.github/workflow.yml
gix-dir/tests/fixtures/generated-do-not-edit/many/613585535-unix/star-in-subdir-and-negated/sub/.github/workflow.yml

The commit that introduces gix into the cargo publish is old enough to be included.
Then again, the src_files seem to depend on the ignore crate via this commit.

This might be the culprit.

cargo/src/cargo/sources/path.rs

Line 578 in 1ce8023

let mut exclude_builder = GitignoreBuilder::new(root);

Is there interest in having this gitoxide'ified?

Closed in favor of something more structured #16547 .

Do you have a minimal reproduction? I am a bit unsure what the expected behavior is, but likely we should investigate the difference and evaluate whether it is a bug or not.

Then I think I know what to do: provide a patch for a test-case that reproduces it. That would also be the first step for a fix.

Thanks!
