v9.0.0

[pytooling-claude]

Note

A new major version, @r9: Python 3.15 becomes the default, MSYS2 runs on UCRT64 only.

• ✨ Python 3.15 (default) and 3.16 (pre-release), PyPy 3.12; application tests can download artifacts.
• ⚠️ MSYS2 runtimes mingw32 and mingw64 removed (with the input mingw64_before_script); Python 3.9, PyPy 3.9
  and 3.10 removed.
• 🔧 Default version lists, exclude and disable lists follow; Python 3.10 warns; pacboy entries for pyEDAA.Reports and
  pyTooling.Sphinx.
• 📖 Version and system lists, every template's defaults; GoatCounter page views.

Important

Merge after Python 3.15.0 is installable on the runners. Until actions/python-versions lists 3.15.0 (it lists
3.15.0-rc.3 today), every job asking for the new default 3.15 fails at setup - including this repository's
verifications, which is why dev is red since the v9.0.0 preparation.

✨ New Features

• Python 3.15 is the latest CPython release, Python 3.16 the pre-release (Add PyPy 3.12 and Python 3.15, Python 3.16 as pre-release #292). 3.15 gets 🟢, 3.16 🟣
  (3.16.0-alpha.1); the older versions move down one level: 3.14 🟢, 3.13 🟡, 3.12 🟠, 3.11 🔴, 3.10 ⚫.

• PyPy 3.12 (pypy-3.12, PyPy 8.0.0) (Add PyPy 3.12 and Python 3.15, Python 3.16 as pre-release #292). It runs on Linux, macOS and Windows on x86-64 and on Linux and macOS
  on arm64; PyPy publishes no Windows-on-arm64 build, so windows-arm:pypy-3.12 is in the default disable_list. Icons:
  pypy-3.11 ⟲🟠, pypy-3.12 ⟲🟡.

• ApplicationTesting.yml downloads artifacts the application tests read (ApplicationTesting: download artifacts the application tests read #296):

  • artifacts_pattern: a glob of artifact names, e.g. 'Example-*'. Empty by default - no download, so existing
    pipelines are unchanged. Named like unittest_artifacts_pattern (PublishTestResults.yml) and
    coverage_artifacts_pattern (PublishCoverageResults.yml).
  • artifacts_directory: where they go, default 'artifacts'; each artifact is extracted into a subdirectory named
    after it.
  • The download runs after the wheel is installed, before the tests, on every system of the matrix.

  AppTesting:
    uses: pyTooling/Actions/.github/workflows/ApplicationTesting.yml@r9
    needs:
      - ExampleJobs
    with:
      artifacts_pattern: 'Example-*'

⚠️ Breaking Changes

• ⚠️ The MSYS2 runtime mingw64 is removed (Remove the MSYS2 runtime 'mingw64' #291). The default system_list (Parameters, CompletePipeline)
  runs MSYS2 on ucrt64 only. A system_list still naming mingw64 gets the warning "System 'mingw64' isn't
  supported anymore." and no job. The deprecation warning of msys2 points to ucrt64.
• ⚠️ UnitTesting and ApplicationTesting lose the input mingw64_before_script (Remove the MSYS2 runtime 'mingw64' #291), with its step. A caller
  still passing it fails at startup (Invalid input) - use ucrt64_before_script. mingw_requirements keeps its name;
  its description says MSYS2.
• ⚠️ The MSYS2 runtime mingw32 is removed (Remove the MSYS2 runtime 'mingw32' #290). A system_list naming it gets the warning "System 'mingw32'
  isn't supported anymore." instead of a job.
• ⚠️ Python 3.9, PyPy 3.9 and PyPy 3.10 are no known versions any more (Add PyPy 3.12 and Python 3.15, Python 3.16 as pre-release #292). Listing them creates no job.
• ⚠️ python_version defaults to '3.15' in every template having it, python_version_list to
  '3.11 3.12 3.13 3.14 3.15' (Parameters, CompletePipeline) (Add PyPy 3.12 and Python 3.15, Python 3.16 as pre-release #292).

Moving a pipeline from @r8 to @r9:

• mingw64_before_script → ucrt64_before_script.
• Remove mingw32/mingw64 from system_list, exclude_list, disable_list and include_list (only warns
  otherwise).
• A pinned python_version of 3.9 or a pypy-3.9/pypy-3.10 entry creates no job any more.

🔧 Changes

• Python 3.10 warns "Support for Python 3.10 ended in 2026.10." when listed (Add PyPy 3.12 and Python 3.15, Python 3.16 as pre-release #292).
• Default lists (Parameters; CompletePipeline's unittest_*/apptest_* lists):
  • exclude_list: 'windows-arm:3.10' (Shift the relative Python versions of the verifications to Python 3.15 #293).
  • disable_list: 'windows-arm:pypy-3.11 windows-arm:pypy-3.12' (Add PyPy 3.12 and Python 3.15, Python 3.16 as pre-release #292).
• ComputePacboyPackages (ComputePacboyPackages: python-jsonschema for pyEDAA.Reports, entries for pyTooling.Sphinx #295):
  • The entries of pyedaa.reports and sphinx_reports list python-jsonschema:p - pyEDAA.Reports validates JSON
    reports with jsonschema, whose dependency rpds-py has compiled code.
  • New entry pytooling.sphinx: python-aiohttp:p (pyTooling[pypi]), python-markupsafe:p (Sphinx); its extra
    reports adds what pyEDAA.Reports needs (jsonschema, lxml, ruamel.yaml) and docstr_coverage (PyYAML).
• The example package myPackage and myFramework.Extension lose their MinGW32/MinGW64 branches, tests/platform its
  MinGW testcases (Remove the MSYS2 runtime 'mingw32' #290, Remove the MSYS2 runtime 'mingw64' #291).

📖 Documentation

• SystemList: mingw32 and mingw64 removed (Remove the MSYS2 runtime 'mingw32' #290, Remove the MSYS2 runtime 'mingw64' #291).
• PythonVersionList: CPython 3.10 to 3.16, PyPy 3.11 and 3.12, with the icons of Parameters (Add PyPy 3.12 and Python 3.15, Python 3.16 as pre-release #292).
• Every template's page states the new defaults of python_version, python_version_list, system_list,
  exclude_list and disable_list; UnitTesting/ApplicationTesting drop mingw64_before_script (Remove the MSYS2 runtime 'mingw32' #290-Shift the relative Python versions of the verifications to Python 3.15 #293).
• ApplicationTesting: the inputs artifacts_pattern and artifacts_directory, and the download step (ApplicationTesting: download artifacts the application tests read #296).
• The published documentation counts its page views with GoatCounter - only a build on GitHub Actions adds the script;
  no cookies (Count the page views of the published documentation with GoatCounter #294).

🧪 Unit Tests

• _Checking_Parameters: the relative test cases (py-0, py-1, ...) follow Python 3.15 as py-0; the default
  matrices expect 3.15 (MSYS2: ucrt64:3.14); Params_Systems checks windows clang64 ucrt64, Params_PythonVersions
pypy-3.11 pypy-3.12 (Remove the MSYS2 runtime 'mingw32' #290-Shift the relative Python versions of the verifications to Python 3.15 #293).
• _Checking_JobTemplates: unit tests also on 3.15 and pypy-3.12, platform tests on clang64 and ucrt64
  (Remove the MSYS2 runtime 'mingw64' #291, Add PyPy 3.12 and Python 3.15, Python 3.16 as pre-release #292). New job ExampleReport uploads an artifact Example-Report, which AppTesting downloads; the new
  testcase DownloadedArtifacts reads it (ApplicationTesting: download artifacts the application tests read #296).
• _Checking_CleanupArtifacts: 3.14 3.15 (Shift the relative Python versions of the verifications to Python 3.15 #293).

Known Issues

• Python 3.15 and 3.16 aren't field-tested yet: 3.15.0 is due 2026-10-09, 3.16.0a1 2026-10-16. Each job asking for one
  of them fails at setup until actions/python-versions lists it.
• On PyPy 8.0 (pypy-3.11, pypy-3.12), packages without a pp80 wheel are built from source, e.g. Pillow (for
  matplotlib) fails on Linux for missing libjpeg headers - Skip the matplotlib testcases on PyPy 8.0 on Linux pyTooling#474.
• CompletePipeline.yml doesn't forward artifacts_pattern/artifacts_directory; pipelines with example jobs wire
  ApplicationTesting by hand.
• tests/pacman_packages.py, the standalone copy of ComputePacboyPackages, lags behind the action.
• Callers to clean up when moving to @r9: pyEDAA.CLITool passes mingw64_before_script; pyTooling names mingw32
  and mingw64 in system lists, pyEDAA.ProjectModel mingw64:* in a disable list.
