Python and Docker Update Workflow Implementation

Original prompt

Create a Python and docker update workflow. This workflow will run periodically like every couple of months and it will check for what the latest version of Python is, and it will find the latest version of docker slim image that works with the Python version that we are looking at. That means the latest version that we just acquired. Then, once it patches these two versions into the other workflows it tests to ensure that that version of Python works with all of our current code and that there aren't new errors introduced by a version, and if there are any attempts to fix the errors and make it so that the new python version will work with our code.

The point of this is to keep the doctor image up-to-date so that we are never behind with latest updates as well as to make sure that our code works with the latest versions of Python that come out, even if no new code has been published in quite a while .

Pull request overview

This PR implements automated Python and Docker version updates to keep the repository's dependencies current without manual intervention. The workflow runs every 2 months, detects the latest stable Python version from Docker Hub, updates version references across multiple files, validates changes through comprehensive testing, and automatically creates a pull request if all tests pass.

Key Changes

Scheduled automation that queries Docker Hub API for latest Python 3.x slim images and updates Dockerfiles and workflow files
Comprehensive validation including linting, pytest, Docker builds, and containerized tests before PR creation
Deduplication logic to prevent multiple open update PRs using the python-update label

+        # Look for tags like "3.12-slim", "3.11-slim", etc.
+        pattern = r'^(\d+\.\d+)-slim$'


The regex pattern only matches Python versions with format "X.Y" (e.g., "3.12") but Docker Hub may also have patch versions like "3.12.1-slim". Consider whether patch version tags should also be detected, or add a comment explaining why only minor versions are matched. The current implementation would miss more specific version tags.

Suggested change

# Look for tags like "3.12-slim", "3.11-slim", etc.

pattern = r'^(\d+\.\d+)-slim$'

# Look for tags like "3.12-slim", "3.11-slim", and also patch tags like

# "3.12.1-slim". We normalize to the major.minor part (e.g. "3.12").

The upper bound of Python 3.20 for version filtering is arbitrary and may become outdated. When Python 3.21 or higher is released, this script will ignore them until the constant is updated. Consider making this more flexible, such as using a higher bound (e.g., 50) or removing the upper bound check entirely since the workflow tests compatibility anyway. The comment at line 46-47 mentions the bound is "intentionally generous" but 3.20 could be reached within a few years.

+        id: current-version

The sed command for extracting the Python version could fail silently if the format changes. The regex pattern expects optional quotes around the version number, but if the YAML format changes (e.g., using unquoted values consistently), the extraction might produce unexpected results. Consider adding validation to ensure the extracted version matches the expected format (e.g., checking it's not empty and matches \d+.\d+), or use a more robust YAML parser.

+    Get the latest stable Python version from python.org.

The docstring says "Get the latest stable Python version from python.org" but the implementation actually queries Docker Hub API. The docstring should be updated to accurately reflect what the function does.

Suggested change

Get the latest stable Python version from python.org.

Returns version string like '3.12' or None on failure.

Determine the latest stable Python 3.x version by querying Docker Hub

`library/python` tags (e.g. "3.12-slim").

The Docker Hub API returns paginated results with page_size=100, which may not capture all available Python versions if there are more than 100 tags. While this is unlikely to miss the latest version (which should appear in the first page), consider adding pagination logic or increasing the page size, or document why 100 is sufficient for this use case.

The branch name uses only the Python version (automated/update-python-${NEW_VERSION}), which could cause issues if multiple update attempts are made for the same version (e.g., after a failed PR is closed and the workflow runs again). The git push at line 162 will fail if the branch already exists. Consider either deleting the remote branch first if it exists, using git push --force, or appending a timestamp/run-id to make branch names unique.

# Push branch (allow updating existing automation branch if it already exists)

The multi-line commit message has inconsistent indentation. The git commit command at line 148 starts a multi-line string, but lines 150-159 have leading spaces that will be included in the commit message verbatim. This creates a commit message with indented bullet points and text, which may look odd in git log. The indentation should either be removed or adjusted so the commit message renders cleanly.

+        result = subprocess.run(

The script calls subprocess.run with a command that includes user-controlled data (python_version) in line 77. While python_version is validated through regex in get_latest_python_version, there's no validation if this function is called independently with arbitrary input. Consider adding input validation to ensure python_version matches expected format before using it in the docker command.

The encoding parameter is missing when reading the workflow file. The function calls workflow_file.read_text() without specifying encoding. Best practice is to explicitly specify encoding='utf-8' for consistency.

Done! The workflow now creates an issue first (with duplicate checking) and then creates a linked PR with the updates. The issue documents the available Python version update and test results, while the PR contains the actual code changes and references the issue with "Closes #X". Both issues and PRs are checked for duplicates using the python-update label. Changes are in commit e8dc8ad.

+          CURRENT_VERSION=$(grep -m1 "python-version:" .github/workflows/build-ci-image.yml | sed -E "s/.*python-version:\s*['\"]?([0-9.]+)['\"]?.*/\1/")
+          echo "version=$CURRENT_VERSION" >> $GITHUB_OUTPUT
+          echo "Using Python $CURRENT_VERSION for workflow execution"


The sed -E expression uses \s*, but GNU/POSIX sed ERE does not support \s as “whitespace”. As written, this will usually fail to match and CURRENT_VERSION becomes the entire line (including spaces), causing actions/setup-python to receive an invalid version string. Use [[:space:]]* (or a simpler parser like awk/python) to reliably extract the version.

Fixed in commit 8b949d9. Changed \s* to [[:space:]]* for POSIX-compatible whitespace matching in sed.

+          echo "new_version=$NEW_VERSION" >> $GITHUB_OUTPUT
+          echo "Updated to Python $NEW_VERSION"


Same issue as earlier: sed -E with \s* won’t match whitespace in sed ERE, so NEW_VERSION can become the full python-version: line instead of just the version. This will break downstream steps (branch name, commit message, PR title). Replace \s* with [[:space:]]* (or use a more robust extraction approach).

Fixed in commit 8b949d9. Changed \s* to [[:space:]]* for POSIX-compatible whitespace matching in sed.

+      - name: Set up Python
+        uses: actions/setup-python@v5
+        with:
+          python-version: ${{ steps.current-version.outputs.version }}
+


This workflow sets up Python using the current version (from build-ci-image.yml) and never re-runs actions/setup-python after updating files. As a result, the venv/lint/pytest steps run on the old Python version, not the newly detected version you’re trying to validate. Add a second actions/setup-python step gated on update_available == 'true' that uses ${{ steps.get-version.outputs.new_version }} before creating the venv and running tests.

Fixed in commit 8b949d9. Added a new "Set up new Python version for testing" step that runs actions/setup-python@v5 with the new version after files are updated, ensuring all tests run with the correct Python version.

+          echo "docker_tests_passed=true" >> $GITHUB_OUTPUT


test-infra:latest sets USER ci (see .github/ci/Dockerfile.infra), but this docker run mounts the repo and tries to create .venv inside /workspace. This likely fails due to filesystem permissions (the existing container-based CI workflows run with options: --user 0, e.g. .github/workflows/pytest.yml:19-21). Run the container as root (--user 0) or write the venv to a writable path (e.g. /tmp`) to match established CI behavior.

Fixed in commit 8b949d9. Added --user 0 flag to the docker run command to match the pattern used in other workflows (e.g., pytest.yml).

The “Handle test failures” step won’t run if flake8/pytest/docker build fails, because those steps will terminate the job before this conditional executes. This contradicts the PR description about reporting specific failures. To make this work, mark the test steps continue-on-error: true and gate the failure-reporting step with if: always() && steps.check-update.outputs.update_available == 'true' (then inspect each step’s outcome/outputs).

Fixed in commit 8b949d9. Added continue-on-error: true to all test steps and changed the failure handler to use if: always() with steps.*.outcome == 'failure' checks, ensuring it executes even when tests fail.

update_file_content() returns False both when a file truly needs no change and when an exception occurs (or the expected pattern wasn’t found). In main(), any such case is silently tolerated as long as some other file changed, which can produce a partial/inconsistent version update (and a PR that doesn’t update all intended references). Track per-file success and fail the script if any target file is missing or still contains the old version/tag when an update is being applied.

Fixed in commit 8b949d9. Enhanced the update logic to track failed files separately and verify that old versions were actually replaced. The script now fails with a clear error message if any file wasn't updated correctly, preventing partial updates.

@copilot : Address the new issues raised by the reviewer

All reviewer issues have been addressed in commit 8b949d9:

Fixed sed regex to use POSIX-compatible [[:space:]]
Added setup-python step to test with the new Python version
Fixed Docker container permissions with --user 0
Added continue-on-error and always() for proper failure handling
Enhanced file update validation to prevent partial updates

- Use regex patterns to check for old versions instead of substring matches - Prevents false positives when new version contains old version as substring - Change always() to !cancelled() in failure handler to avoid running on cancellation Co-authored-by: zaxlofful <33877007+zaxlofful@users.noreply.github.com>
