Compiles polars' PyO3/maturin Rust extension under the package name upstream ships for pre-AVX2 x86 hosts. Upstream publishes no riscv64 wheel.

Mirrors upstream's release-python.yml.

Differs from upstream

  • Skips the x86-64 CPU-feature RUSTFLAGS step - upstream itself only runs it if: matrix.architecture == 'x86-64', so on riscv64 polars-lts-cpu compiles byte-for-byte the same as plain polars, just renamed.
  • Drops fat LTO/codegen-units=1 from the dist-release profile - same fix build-polars-runtime.yml already needed on these runners.

Testing

  • same as build-polars-runtime.yml (this repo's other polars build, same crate graph): smoke import + show_versions(), not the full pytest suite.
