Replace milksnake with maturin #2393

luizirber · 2022-12-03T22:10:51Z

While investigating why the Python 3.11 PR failed in conda-forge I found out that there is an error in milksnake. Main issue is that milksnake seems to be abandoned, without recent releases, so submitting a PR to fix there might be unfruitful.

maturin is a PEP517-compatible backend for building packages and aimed at Rust packages (pure or mixed with more Python code, like sourmash). It is actively maintained, and supports the cffi bindings case that we use too.

This PR is based on pyocd/cmsis-pack-manager#195
Closes #1564 (previous try with setuptools-rust)

TODO

~~there is no support for setuptools_scm with maturin. Need to replace/version properly.~~ turns out that setuptools_scm is doing something that PyPA doesn't recommend anymore. From core metadata and PEP 643:

The fields Name and Version MUST NOT be marked as Dynamic.
Fix maturin develop/tox -e dev, currently failing.
Figure out how to pull Cargo.lock from workspace root. Maturin support for workspace is lacking, so the way I found to solve it (use the core crate Cargo.toml directly) expect the lock file to be src/core/Cargo.lock, but that doesn't exist.
Versioning. There is no support for dynamic version based on VCS tags (like setuptools_scm does), so we need to change the release process =/
- Might be an opportunity to introduce release-please, example from rust-bio here with conventional commits checker here. This combination is nice because changing the PR title is enough to satisfy checks (and generate the changelog).

FYI, something like this will also work as long as you release from CI:

Feel free to open an issue in maturin if it's better to be solved in upstream.

The versioning is still pending, but I propose doing it in another PR because this one already have many moving parts...

rayon-core requires 1.56.1, so that's our MSRV now.

general query: is there a reason not to update the MSRV regularly anyway? It shouldn't matter for most things, right?

general query: is there a reason not to update the MSRV regularly anyway? It shouldn't matter for most things, right?

Initially I was trying to follow LTS releases or what Debian supported, thinking that it would make it easier to package there.
For example, current Debian stable (bullseye) is 1.48: https://tracker.debian.org/pkg/rustc
(Ubuntu releases it in the security channel, so even 18.04 has Rust 1.61: https://packages.ubuntu.com/bionic/rustc)

But... there are no sourmash packages in either of them.

I don't think we should go updating MSRV every release, but 1.56.1 isa good one because it is the introduction of the 2021 edition.

make sure that we track optional features too, so dependabot won't leave us in a broken situation.

Looks good! When you merge, can you create a new issue about updating the release process?

You could review & merge #2386 at the same time :)
