CPython

Contributed CI infrastructure work directly to the Python interpreter itself.

jenkinsapi — De Facto Maintainer

pycontribs/jenkinsapi is the primary Python library for programmatic Jenkins interaction. After it fell into disrepair, a significant effort was made to rescue and modernize it — resulting in 50+ merged PRs and multiple version releases.

Rescue and Modernization

PEP 541 request (pypi/support #5414) — Formally claimed the abandoned jenkinsapi PyPI package name through the PEP 541 process.
Migrated build backend to hatchling from legacy setup.py (PR #960)
Migrated to uv for dependency management (PR #971)
Dropped Python 3.8 support (PR) and added Python 3.14 (PR #1037)
Java 25 support (PR #1000)
Bumped version to 0.3.20 (PR #1051)

Features Added

Pipeline stages and results — New functionality to return pipeline stage data and results (PR #1049)
Node label helpers — add_labels, modify_labels, delete_labels (PR)
Jenkins folder support — Handle jobs within folders (PR #1058, open)
SCM type fix — Fix get_scm_type (PR #1011)
Docker test parallelization (PR #1050, open)
Increased default retry count to 3 (PR)

CI and Test Stability

Fixed intermittently failing tests across multiple PRs
Set relative paths in jenkins_launcher for portability
Added env vars for test configuration
Updated get-jenkins-war.sh to handle missing latest tag from Jenkins download server
Switched to Azure mirror for plugin downloads (faster than Jenkins mirrors)
Pinned all GHA actions to SHAs for security
Added ruff to pre-commit, enabled auto-fixes
Removed tox and pycodestyle as dependencies
