From 4422d1bedc05987c4618201a6f8057c1d504c2c5 Mon Sep 17 00:00:00 2001 From: Matteo Pologruto Date: Mon, 19 Sep 2022 11:33:24 +0200 Subject: [PATCH] Add CI workflow to check the license file Whenever one of the recognized license file names are modified in the repository, the workflow runs to check whether the license can be recognized and whether it is of the expected type. GitHub has a useful automated license detection system that determines the license type used by a repository, and surfaces that information in the repository home page, the search web interface, and the GitHub API. This license detection system requires that the license be defined by a dedicated file with one of several standardized filenames and paths. GitHub's license detection system uses the popular licensee tool, so this file also serves to define the license type for any other usages of licensee, as well as to human readers of the file. For this reason, and to ensure it remains a valid legal instrument, it's important that there be no non-standard modifications to the license file or collisions with other supported license files. This workflow ensures that any changes which would change the license type or which license file is used by the detection are caught automatically. --- .github/workflows/check-license.yml | 96 +++++++++++++++++++++++++++++ README.md | 1 + 2 files changed, 97 insertions(+) create mode 100644 .github/workflows/check-license.yml diff --git a/.github/workflows/check-license.yml b/.github/workflows/check-license.yml new file mode 100644 index 00000000..af57f3ea --- /dev/null +++ b/.github/workflows/check-license.yml @@ -0,0 +1,96 @@ +# Source: https://github.com/arduino/tooling-project-assets/blob/main/workflow-templates/check-license.md +name: Check License + +env: + EXPECTED_LICENSE_FILENAME: LICENSE + # SPDX identifier: https://spdx.org/licenses/ + EXPECTED_LICENSE_TYPE: GPL-3.0 + +# See: https://docs.github.com/actions/using-workflows/events-that-trigger-workflows +on: + create: + push: + paths: + - ".github/workflows/check-license.ya?ml" + # See: https://github.com/licensee/licensee/blob/master/docs/what-we-look-at.md#detecting-the-license-file + - "[cC][oO][pP][yY][iI][nN][gG]*" + - "[cC][oO][pP][yY][rR][iI][gG][hH][tH]*" + - "[lL][iI][cC][eE][nN][cCsS][eE]*" + - "[oO][fF][lL]*" + - "[pP][aA][tT][eE][nN][tT][sS]*" + pull_request: + paths: + - ".github/workflows/check-license.ya?ml" + - "[cC][oO][pP][yY][iI][nN][gG]*" + - "[cC][oO][pP][yY][rR][iI][gG][hH][tH]*" + - "[lL][iI][cC][eE][nN][cCsS][eE]*" + - "[oO][fF][lL]*" + - "[pP][aA][tT][eE][nN][tT][sS]*" + schedule: + # Run periodically to catch breakage caused by external changes. + - cron: "0 6 * * WED" + workflow_dispatch: + repository_dispatch: + +jobs: + run-determination: + runs-on: ubuntu-latest + outputs: + result: ${{ steps.determination.outputs.result }} + steps: + - name: Determine if the rest of the workflow should run + id: determination + run: | + RELEASE_BRANCH_REGEX="refs/heads/[0-9]+.[0-9]+.x" + # The `create` event trigger doesn't support `branches` filters, so it's necessary to use Bash instead. + if [[ + "${{ github.event_name }}" != "create" || + "${{ github.ref }}" =~ $RELEASE_BRANCH_REGEX + ]]; then + # Run the other jobs. + RESULT="true" + else + # There is no need to run the other jobs. + RESULT="false" + fi + + echo "::set-output name=result::$RESULT" + + check-license: + needs: run-determination + if: needs.run-determination.outputs.result == 'true' + runs-on: ubuntu-latest + + steps: + - name: Checkout repository + uses: actions/checkout@v3 + + - name: Install Ruby + uses: ruby/setup-ruby@v1 + with: + ruby-version: ruby # Install latest version + + - name: Install licensee + run: gem install licensee + + - name: Check license file + run: | + EXIT_STATUS=0 + # See: https://github.com/licensee/licensee + LICENSEE_OUTPUT="$(licensee detect --json --confidence=100)" + + DETECTED_LICENSE_FILE="$(echo "$LICENSEE_OUTPUT" | jq .matched_files[0].filename | tr --delete '\r')" + echo "Detected license file: $DETECTED_LICENSE_FILE" + if [ "$DETECTED_LICENSE_FILE" != "\"${EXPECTED_LICENSE_FILENAME}\"" ]; then + echo "::error file=${DETECTED_LICENSE_FILE}::detected license file $DETECTED_LICENSE_FILE doesn't match expected: $EXPECTED_LICENSE_FILENAME" + EXIT_STATUS=1 + fi + + DETECTED_LICENSE_TYPE="$(echo "$LICENSEE_OUTPUT" | jq .matched_files[0].matched_license | tr --delete '\r')" + echo "Detected license type: $DETECTED_LICENSE_TYPE" + if [ "$DETECTED_LICENSE_TYPE" != "\"${EXPECTED_LICENSE_TYPE}\"" ]; then + echo "::error file=${DETECTED_LICENSE_FILE}::detected license type $DETECTED_LICENSE_TYPE doesn't match expected \"${EXPECTED_LICENSE_TYPE}\"" + EXIT_STATUS=1 + fi + + exit $EXIT_STATUS diff --git a/README.md b/README.md index 03f0074e..7aa380b7 100644 --- a/README.md +++ b/README.md @@ -4,6 +4,7 @@ ![test](https://github.com/arduino/setup-protoc/workflows/test/badge.svg) [![Sync Labels status](https://github.com/arduino/setup-protoc/actions/workflows/sync-labels-npm.yml/badge.svg)](https://github.com/arduino/setup-protoc/actions/workflows/sync-labels-npm.yml) [![Check Markdown status](https://github.com/arduino/setup-protoc/actions/workflows/check-markdown-task.yml/badge.svg)](https://github.com/arduino/setup-protoc/actions/workflows/check-markdown-task.yml) +[![Check License status](https://github.com/arduino/setup-protoc/actions/workflows/check-license.yml/badge.svg)](https://github.com/arduino/setup-protoc/actions/workflows/check-license.yml) This action makes the `protoc` compiler available to Workflows.
