bpo-39837 made Azure Pipelines CI non-mandatory. Travis CI was made mandatory to have at least one mandatory job: https://github.com/python/core-workflow/issues/365 I would prefer to have at least one mandatory Windows CI running on Python pull requests. Before we had pre-commit checks, it was too common to break Windows. I would prefer to not regress on that aspect. -- Currently, GitHub action jobs ignore "documentation-only" changes. Extract of .github/workflows/build.yml: on: push: branches: - master - 3.8 - 3.7 paths-ignore: - 'Doc/**' - 'Misc/**' - '**/*.md' - '**/*.rst' If a job is marked as mandatory but the GitHub action is skipped because of paths-ignore, the PR cannot be merged :-( It seems to be a known GitHub limitation which is not going to be fixed soon: https://discuss.python.org/t/make-one-windows-ci-job-mandatory/4047/6 To workaround is to always run GitHub action jobs, even on documentation-only jobs. I propose to always run GitHub actions and then make the Windows (64 bit) job mandatory. -- Sadly, it will waste resources for documentation-only jobs. To avoid that, the Windows job can be modified later to be skipped if it detects that the PR is a documentation-only change. Steve Dower wrote: "That workaround looks roughly like what is in the Azure Pipelines files. Someone just needs the time to go and migrate it." https://discuss.python.org/t/make-one-windows-ci-job-mandatory/4047/6 Note: the Travis CI job (.travis.yml) uses the following check: # Pull requests are slightly complicated because $TRAVIS_COMMIT_RANGE # may include more changes than desired if the history is convoluted. # Instead, explicitly fetch the base branch and compare against the # merge-base commit. git fetch -q origin +refs/heads/$TRAVIS_BRANCH changes=$(git diff --name-only HEAD $(git merge-base HEAD FETCH_HEAD)) echo "Files changed:" echo "$changes" if ! echo "$changes" | grep -qvE '(\.rst$)|(^Doc)|(^Misc)' then echo "Only docs were updated, stopping build process." exit fi -- More background on these CI issues: * https://bugs.python.org/issue39837 * https://github.com/python/core-workflow/issues/365 * https://discuss.python.org/t/make-one-windows-ci-job-mandatory/4047

The workaround presented at https://github.community/t5/GitHub-Actions/Feature-request-conditional-required-checks/m-p/51344/highlight/true#M8157 seems pretty reasonable. And it seems like travis is alerady doing the same thing as it doesn't have native support to skip runs based on path changes. I can open a PR if you want.

And it seems like travis is alerady doing the same thing as it doesn't have native support to skip runs based on path changes. I suppose that Steve Dower mentioned the following part of .azure-pipelines/prebuild-checks.yml: ---------------- - script: | if ! git diff --name-only $(diffTarget) | grep -qvE '(\.rst$|^Doc|^Misc)' then echo "Only docs were updated: tests.run=false" echo "##vso[task.setvariable variable=run;isOutput=true]false" else echo "Code was updated: tests.run=true" echo "##vso[task.setvariable variable=run;isOutput=true]true" fi displayName: Detect source changes name: tests ---------------- I understood that he proposed to port it inside the Windows job of GitHub actions (.github/workflows/build.yml). I propose the following plan: * Always run GitHub Action jobs * Make Windows 64-bit job mandatory * And only then try to skip documentation-only changes

> * And only then try to skip documentation-only changes Done :)
