feat: add changelog generation script with GitHub API integration by rtibblesbot · Pull Request #149 · learningequality/kolibri-installer-debian

rtibblesbot · 2026-02-20T17:59:07Z

Summary

Adds build_tools/generate_changelog.py that automates Debian changelog generation from Kolibri's GitHub releases, replacing the manual single-entry dch approach
Implements core changelog parsing, version comparison, entry formatting, and GitHub API integration with pagination
Adds 17 comprehensive tests covering all functionality

This is the foundation (Phases 1-2) for #133. The script can parse the existing debian/changelog, fetch releases from GitHub's API, filter to only new versions, and generate properly formatted Debian changelog entries. Phases 3-4 (CHANGELOG interleaving and build.sh integration) will follow in subsequent PRs.

References

Closes phase 1-2 of Create a Python script to automatically generate the updated Debian changelog #133
Follow-up work needed for phases 3-4 (CHANGELOG parsing/interleaving, build integration)

Reviewer guidance

The script is not yet wired into the build process — it's standalone and testable
All GitHub API interactions are mocked in tests; distro-info calls are also mocked since the package is system-only
Key areas to review:
- Version comparison logic in normalize_version() and kolibri_version_key() — handles Kolibri's non-PEP-440 prerelease formats
- version_to_debian() conversion — maps alpha/beta/rc/dev suffixes to Debian ~ convention
- Pagination handling in fetch_github_releases() via Link header parsing
To run tests: python3 -m pytest tests/ -v
The packaging library is used for version comparison — it's ubiquitous with pip but is technically an external dependency

Test evidence

All 17 tests pass:

Test scenarios covered:

Changelog parsing: Extracts latest version from real debian/changelog format; preserves full content
Version ordering: Stable versions sort correctly; prereleases sort before their stable counterparts
Prerelease detection: Identifies alpha, beta, rc, and dev versions
Entry formatting: Generates correct Debian changelog stanzas for both stable and prerelease versions
Timestamp conversion: ISO 8601 GitHub timestamps convert to RFC 2822 Debian format
GitHub API: Single-page and multi-page (paginated) response handling with mocked urllib
Release filtering: Excludes versions older than changelog; excludes prereleases by default; includes prereleases when they match the build version; strips v prefix from tag names
Entry generation: End-to-end test from release data to formatted changelog entries with mocked distro-info

Sorry, I'm confused by why you've submitted a PR for half the issue?

Also, as we're adding Python tests to this repository for the first time, we should also setup Github Actions CI integration to run the Python tests, as well as some indication for a user of this repository what needs to be installed to run tests, and how?

Core changelog parsing, version comparison, and GitHub API integration are clean and well-tested. CI passing.

This is still not completing all the acceptance criteria of the issue. This work must be completed within this pull request.

blocking (2): PR will auto-close #133 despite unmet acceptance criteria; distro-info dependency undeclared — see inline comments
suggestion (2): GitHub API auth token support, version comparison robustness — see inline comments

CI failure. With it actually hooked into the build, it seems to have immediately failed. Did you try building locally? Will need to fetch a recent kolibri release to do this.

Add build_tools/generate_changelog.py that automates Debian changelog generation from Kolibri's GitHub releases. This replaces the manual single-entry `dch` approach with a script that can generate entries for all releases newer than the current changelog version. Includes: - Debian changelog parsing to detect current version - Kolibri version comparison with prerelease handling - Debian changelog entry formatting with proper version conversion - GitHub API client with pagination support - Release filtering (excludes prereleases unless matching build version) - Ubuntu LTS codename detection via distro-info Part of learningequality#133 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

A bit more cleanup needed.

+    if UbuntuDistroInfo is None:
+        raise ImportError(
+            "distro-info package is required. "
+            "Install with: sudo apt install python3-distro-info"


Why aren't we running this in any of our github actions builds now?

Feels like we should run it in the tests CI (and not mock this package) and in the build CI action.

Fixed — python3-distro-info is now installed in both the test CI and build CI workflows. Tests no longer mock get_current_lts_codename; they use the real package (skipping gracefully when not installed locally). Build CI also installs packaging for the changelog script.

Add 17 tests covering all changelog generation functionality: - Debian changelog parsing and content preservation - Version ordering and prerelease detection - Changelog entry formatting for stable and prerelease versions - GitHub timestamp to Debian format conversion - GitHub API fetching with pagination (mocked) - Release filtering logic (old versions, prereleases, v-prefix stripping) - End-to-end entry generation from release data Also adds build_tools/__init__.py to enable test imports.

Some more cleanup and potential to mock in a way that gives much stronger confidence.

Couldn't this just be pip install .

I think I would prefer to just fail if this isn't present, no need to guard the import.

I think it would be better to use the VCR py library this mocking. That way we can be sure we are testing against real API data. Generate the cassettes locally and commit them.
