antsibull -- Ansible Build Scripts

Tooling for building various things related to Ansible

Scripts that are here:

• antsibull-build - Builds Ansible-2.10+ from component collections (docs)

Related projects are antsibull-changelog and antsibull-docs, which are in their own repositories (antsibull-changelog repository, antsibull-docs repository). Currently antsibull-changelog is a dependency of antsibull. Therefore, the scripts contained in it will be available as well when installing antsibull.

You can find a list of changes in the Antsibull changelog.

antsibull is covered by the Ansible Code of Conduct.

Licensing

This repository abides by the REUSE specification. See the copyright headers in each file for the exact license and copyright. Summarily:

• The default license is the GNU Public License v3+ (GPL-3.0-or-later).
• src/antsibull/_vendor/shutil.py includes code derived from CPython, licensed under the Python 2.0 License (Python-2.0.1).

Versioning and compatibility

From version 0.1.0 on, antsibull sticks to semantic versioning and aims at providing no backwards compatibility breaking changes to the command line API (antsibull) during a major release cycle. We might make exceptions from this in case of security fixes for vulnerabilities that are severe enough.

We explicitly exclude code compatibility. antsibull is not supposed to be used as a library. The only exception are potential dependencies with other antsibull projects (currently, none). If you want to use a certain part of antsibull as a library, please create an issue so we can discuss whether we add a stable interface for parts of the Python code. We do not promise that this will actually happen though.

Development

Install and run nox to run all tests. That's it for simple contributions! nox will create virtual environments in .nox inside the checked out project and install the requirements needed to run the tests there.

---

antsibull depends on the sister antsibull-core and antsibull-changelog projects. By default, nox will install development versions of these projects from Github. If you're hacking on antsibull-core or antsibull-changelog alongside antsibull, nox will automatically install the projects from ../antsibull-core and ../antsibull-changelog when running tests if those paths exist. You can change this behavior through the OTHER_ANTSIBULL_MODE env var:

• OTHER_ANTSIBULL_MODE=auto — the default behavior described above
• OTHER_ANTSIBULL_MODE=local — install the projects from ../antsibull-core and ../antsibull-changelog. Fail if those paths don't exist.
• OTHER_ANTSIBULL_MODE=git — install the projects from the Github main branch
• OTHER_ANTSIBULL_MODE=pypi — install the latest version from PyPI

To run specific tests:

1. nox -e test to only run unit tests;
2. nox -e lint to run all linters;
3. nox -e formatters to run isort and black;
4. nox -e codeqa to run flake8, pylint, reuse lint, and antsibull-changelog lint;
5. nox -e typing to run mypy and pyre.
6. nox -e coverage_release to build a test ansible release. This is expensive, so it's not run by default.
7. nox -e check_package_files to run the generate-package-files integration tests. This is somewhat expensive and thus not run by default.
8. nox -e coverage to display combined coverage results after running nox -e test coverage_release check_package_files;

Run nox -l to list all test sessions.

To create a more complete local development env:

git clone https://github.com/ansible-community/antsibull-changelog.git
git clone https://github.com/ansible-community/antsibull-core.git
git clone https://github.com/ansible-community/antsibull.git
cd antsibull
python3 -m venv venv
. ./venv/bin/activate
pip install -e '.[dev]' -e ../antsibull-changelog -e ../antsibull-core
[...]
nox

Creating a new release:

1. Run nox -e bump -- <version> <release_summary_message>. This:
   • Bumps the package version in src/antsibull/__init__.py.
   • Creates changelogs/fragments/<version>.yml with a release_summary section.
   • Runs antsibull-changelog release and adds the changed files to git.
   • Commits with message Release <version>. and runs git tag -a -m 'antsibull <version>' <version>.
   • Runs hatch build --clean to build an sdist and wheel in dist/ and clean up any old artifacts in that directory.
2. Run git push to the appropriate remotes.
3. Once CI passes on GitHub, run nox -e publish. This:
   • Runs hatch publish to publish the sdist and wheel generated during step 1 to PyPI;
   • Bumps the version to <version>.post0;
   • Adds the changed file to git and runs git commit -m 'Post-release version bump.';
4. Run git push --follow-tags to the appropriate remotes and create a GitHub release.
