cargo does not see `Cargo.toml` if `.gitignore` contains `/*`

[cospectrum]

Problem

If .gitignore is written in the style of "ignore everything except this", then cargo package --list for some reason does not see anything.
It seems to me that everything was fine on previous versions, I spent an hour investigating, did I miss something?

cargo version: 1.80.1 (376290515 2024-07-16)
git version 2.39.2 (Apple Git-143)
OS: mac

Cargo.toml:

[package]
name = "gitignore-bug"
version = "0.1.0"
edition = "2021"
license = "MIT"
description = "to reproduce bug"

[dependencies]

.gitignore:

/target
/*
!.gitignore
!Cargo.toml
!src

cargo package --list

warning: manifest has no documentation, homepage or repository.
See https://doc.rust-lang.org/cargo/reference/manifest.html#package-metadata for more info.
warning: no `Cargo.toml` file found when packaging `gitignore-bug` (note the case of the file name).
.cargo_vcs_info.json
Cargo.lock

Steps

cargo init
echo '\n/*\n\n!.gitignore\n!Cargo.toml\n!src' >> .gitignore
git add . && git commit -m "."
cargo package --list

No response

Notes

cargo build is working, cargo publish is not working

Thanks for the report, though I cannot reproduce it.

When you run git ls-files on that repository, what is the output?

Mine is

$ git ls-files
.gitignore
Cargo.toml
src/main.rs

cargo package --list queries git index to get the file list. If they are in the git index, they shall be packaged.

Sorry. Clicked the wrong button 🙇🏾‍♂️.

git ls-files gives the same output as yours

I did the correct list of files on macOS.

$ cargo +1.80.1 package --list
warning: manifest has no description, license, license-file, documentation, homepage or repository.

.cargo_vcs_info.json
.gitignore
Cargo.lock
Cargo.toml
Cargo.toml.orig
src/main.rs

Do you have any special Git configuration on your machine?
(~/.gitconfig or git/config under the repo)

Is it possible on your side to bisect which version starts failing? Note that Cargo switched to gitoxide for file listing in 1.79.0. You could try __CARGO_GITOXIDE_DISABLE_LIST_FILES=1 cargo package --list and see if it works.

[cospectrum]

__CARGO_GITOXIDE_DISABLE_LIST_FILES=1 cargo package --list is working correctly

[cospectrum]

toolchain version 1.78.0 is working, 1.79.0 is not

@cospectrum it might help if you can provide some information about this.
