This project should help maintainers reduce toil and save time in the release process by enforcing best practices to:

  • Automate a changelog for every release

  • Pre-publish to test server and verify the install and import of dist asset(s)

  • Commit a message with hashes of dist file(s)

  • Annotate the git tag in standard format

  • Create a GitHub release with changelog entry

  • Verify url links in markdown and reStructuredText files

  • Verify integrity of Python manifest

  • Forward port changelog entries into default branch

  • Dry run publish on CI

  • Revert to Dev version after release (optional)

Workflow Details#

Detailed workflows are available to draft a changelog, draft a release, publish a release, and check a release.

Draft ChangeLog Workflow#

  • Manual Github workflow

    • Inputs are the target repo, branch, and the version spec

  • Bumps the version

    • By default, uses tbump or bump2version to bump the version based on presence of config files

      • We recommend tbump instead of bump2version for most cases because it does not handle patch releases well when using prereleases.

  • Prepares the environment

    • Sets up git config and branch

  • Generates a changelog (using github-activity) using the PRs since the last tag on this branch.

    • Gets the current version and then does a git checkout to clear state

    • Adds a new version entry using a HTML comment markers in the changelog file

    • Optionally resolves meeseeks backport PRs to their original PR

  • Creates a PR with the changelog changes

  • Can be re-run using the same version spec. It will add new entries but preserve existing ones (in case they have been hand modified).

  • Note: Pre-release changelog sections are not automatically combined, but you may wish to do so manually.

Draft Release Workflow#

  • Manual Github workflow

    • Inputs are target repository, branch, version spec and optional post version spec

  • Bumps version using the same method as the changelog action

  • Prepares the environment using the same method as the changelog action

  • Checks the changelog entry

    • Looks for the current entry using the HTML comment markers

    • Gets the expected changelog values using github-activity

    • Ensures that all PRs are the same between the two

  • For Python packages:

    • Builds the wheel and source distributions if applicable

    • Makes sure Python dists can be installed and imported in a virtual environment

  • For npm package(s) (including workspace support):

    • Builds tarball(s) using npm pack

    • Make sure tarball(s) can be installed and imported in a new npm package

  • Checks the package manifest using check-manifest

  • Checks the links in Markdown and reStructuredText files

  • Adds a commit that includes the hashes of the dist files

  • Creates an annotated version tag in standard format

  • If given, bumps the version using the post version spec. he post version spec can also be given as a setting, Write Releaser Config Guide.

  • Pushes the commits and tag to the target branch

  • Publishes a draft GitHub release for the tag with the changelog entry as the text

Publish Release Workflow#

  • Manual Github workflow

    • Input is the url of the draft release

  • Downloads the dist assets from the release

  • Verifies shas and integrity of release assets

  • Publishes assets to appropriate registries

  • If the tag is on a backport branch, makes a forwardport PR for the changelog entry

Check Release Workflow#

  • Runs on CI in the target repository to verify compatibility and release-ability.

  • Runs the Draft Changelog and Draft Release actions in dry run mode

  • Publishes to the local PyPI server and/or dry-run npm publish.

  • Does not make PRs or push git changes
