The release workflow for PyObjC

This is a description of the workflow for pushing out a new release of PyObjC.

Note

This document is a work in progress.

The release workflow consists of a number of steps, each of which will be described below.

  1. Ensure that PyObjC works on all supported platforms.

  2. Update version number for release

  3. Create distributions artifacts with smoke test

  1. Tag the release

  2. Create a GitHub release

  3. Update the PyObjC website

  4. Upload the new release

  5. Update the version in the repository

  6. Announce the new release

Ensure that PyObjC works

Run development-support/run-testsuite on the build machine running the latest release of macOS and check the report at the end for errors. When you do get errors: fix the problems and start over.

Before the first release supporting a new major release of macOS also run the test suite on a number of older versions of macOS.

Update version number for release

Run development-support/set-pyobjc-version VERSION where VERSION is the version number for the upcoming release, and commit the changes.

Create distribution artifacts

The machines used to create the distribution archives are two VMs running macOS 10.13 and 10.14 with the following additional software:

  • up to date version of Xcode

  • up to date versions of the supported Python versions

    All of these are installed using the python.org binary installer (universal) and during installation only the framework itself is installed (nothing in /usr/local, no GUI tools)

The script “development-support/collect-dist-archives” creates all distribution archives, but is not called directly.

Tag the release

Create a tag in the pyobjc repository. The tag name is “vVERSION” (with VERSION replaced by the correct version).

Push to GitHub.

Create a GitHub release

Create a GitHub release using the newly pushed tag and the changelog for the current version.

The release artefacts created by GitHub are not used in the release process.

Update the PyObjC website

The PyObjC website is automatically updated after push to GitHub.

Upload the new release

Use “twine” to upload the source and wheel archives created earlier to PyPI.

Check the website

Check that https://pyobjc.readthedocs.io/en/latest/ contains the release notes for the current release

Send out announcement

  1. Create a blog entry on my blog describing the new release

  2. Mention the blog entry on X/Twitter/Mastondon.
