Dependencies not added to the wheel metadata

[calavera]

Bug Description

Dependencies specified in pyproject.toml are not added to the final METADA file in the dist-info directory.

I have a project with this information in the pyproject.toml file:

[project]
name = "cargo-lambda"
dependencies = ["ziglang>=0.9.0"]

When I read the documentation, I understood that Maturin would use that information to make sure that the dependencies are installed when someone runs pip install cargo-lambda. This is not the case.

For what I can tell, the dist-info/METADATA files doesn't include the dependency as Requires-Dist, is there anything that I'm missing?

This is the header if my dist-info/METADATA:

❯ cat cargo_lambda-0.10.0.dist-info/METADATA
Metadata-Version: 2.1
Name: cargo-lambda
Version: 0.10.0
Summary: Cargo subcommand to work with AWS Lambda
Keywords: cargo,subcommand,aws,lambda

Your Python version (python -V)

Python 3.8.10

Your pip version (pip -V)

pip 20.0.2

What bindings you're using

No response

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Steps to Reproduce

1. Clone cargo-lambda with git clone [email protected]:cargo-lambda/cargo-lambda
2. Generate a wheel with maturin --release -o dist --strip -m crates/cargo-lambda-cli/Cargo.toml
3. Unzip the generated wheel
4. Verify that dist-info/METADATA doesn't include Requires-Dist.

maturin/src/project_layout.rs

Lines 132 to 135 in e27200d

	// use command line argument if specified
	if let Some(path) = cargo_manifest_path {
	return Ok((path.clone(), path.parent().unwrap().join(PYPROJECT_TOML)));
	}

The problem is that when you specified Cargo manifest path in cli, maturin currently assumes pyproject.toml is in the same directory which isn't true in this case.

I planned to fix it in #1009 but forgot about it when implementing #1043, thanks for posting the issue.

Please try #1054.

BTW, currently maturin cannot build source distribution for your project even after #1054 due to the following error:

$ maturin sdist -o dist -m crates/cargo-lambda-cli/Cargo.toml
🔗 Found bin bindings
📡 Using build options bindings from pyproject.toml
💥 maturin failed
  Caused by: Failed to build source distribution
  Caused by: pyproject.toml was not included by `cargo package`. Please make sure pyproject.toml is not excluded or build without `--sdist`

Consider move pyproject.toml to crates/cargo-lambda-cli/ directory.

Consider move pyproject.toml to crates/cargo-lambda-cli/ directory.

I can give that a try

Moving the pyproject.toml file worked, btw. You might want to consider updating your documentation to help other people.
