publish-python-release

name	publish-python-release
description	Build or publish nemo-switchyard Python distributions through the repository's GitHub Actions workflow. Use when asked to build a development wheel, cut a Python release, publish to PyPI, create a release tag, or debug .github/workflows/publish.yml.

Publish The Python Package

Use .github/workflows/publish.yml as the source of truth. The supporting runbook is docs/internal/release_workflow.md.

Release Paths

Intent	Trigger	Result
One temporary wheel	Manual dispatch with build_dev_artifact=true	Linux x86_64 GitHub artifact, retained for one day
Full matrix test	Manual dispatch with build_dev_matrix=true	sdist and wheel artifacts; no publish
Official release	Push vMAJOR.MINOR.PATCH matching pyproject.toml	Full matrix, PyPI publish, GitHub Release

Manual builds are artifact-only. Official releases use PyPI Trusted Publishing through the GitHub environment named pypi; do not add a long-lived PyPI token.

Workflow

1. Read the current workflow and pyproject.toml; do not rely on remembered inputs or versions.
2. Confirm the requested version and whether the user explicitly authorized creating a tag.
3. For workflow changes, run the focused release-helper tests and inspect the workflow diff.
4. Dispatch a development build or push the authorized release tag.
5. Monitor every matrix job and verify the resulting package from a clean temporary environment.

Example development dispatch:

gh workflow run publish.yml \
  -f build_dev_artifact=true \
  -f build_dev_matrix=false \
  -f dev_version=0.0.1.dev0

Guardrails

• Never create or push a tag unless the user explicitly requested it.
• Never publish a manual development build to PyPI.
• Never reuse a deleted PyPI filename or version; PyPI permanently reserves filenames.
• Keep release versions consistent across the tag, pyproject.toml, and package metadata.
• Verify installation outside the checkout so local imports cannot mask packaging defects.
• Cargo crate publishing is a separate manual workflow. Inspect each crate's Cargo.toml, dependency publication order, and crates.io ownership before running cargo publish.
