action-ros-ci

This action builds a ROS, or ROS 2 workspace from source, and run colon-test on the package under test.

Requirements

This action requires the following ROS development tools to be installed (and initialized if applicable) on the CI worker instance:

curl
colcon-common-extensions
colcon-lcov-result  # Optional
colcon-mixin
rosdep
vcstool

On Linux, the setup can be done through ros-tooling/setup-ros, or by running the action in a Docker image containing the appropriate binaries.

Overview

The action first assembles a workspace, then run colcon build, and colcon test in it.

The workspace is built by running:

• vcs import on the repo file specified through the vcs-repo-file-url argument (defaults to https://raw.githubusercontent.com/ros2/ros2/master/ros2.repos).
• checkout the code under test in the workspace using vcs
• run colcon build for all packages specified in package-name
• run colcon test for all packages specified in package-name

Action Output

This action defines an output variable ros-workspace-directory-name. It contains the path to the root of the ROS workspace assembled by the action.

The variable value should be used to retrieve logs, binaries, etc. after the action completes.

Usage

See action.yml to get the list of flags supported by this action.

action-ros-ci-template offers a template for using action-ros-ci

Build and run ament_copyright tests

steps:
- uses: ros-tooling/setup-ros@0.0.18
- uses: ros-tooling/action-ros-ci@0.0.15
  with:
    package-name: ament_copyright

Build with a custom repos or rosinstall file

You can specify your own repos file using the vcs-repo-file-url input. You can also automatically generate your package's dependencies using the following workflow:

steps:
- uses: actions/checkout@v2
- uses: ros-tooling/setup-ros@0.0.18
# Run the generator and output the results to a file.
- run: |
    rosinstall_generator <package-name> --rosdistro <target-distro> \
    --deps-only --deps --upstream-development > /tmp/deps.repos
# Pass the file to the action
- uses: ros-tooling/action-ros-ci@0.0.15
  with:
    package-name: my_package
    vcs-repo-file-url: /tmp/deps.repos

Enable Address Sanitizer to automatically report memory issues

ASan is an open-source tool developed to automatically report memory corruption bugs.

    steps:
    - uses: ros-tooling/setup-ros@0.0.19
    - uses: ros-tooling/action-ros-ci@0.0.15
      with:
        colcon-mixin-name: asan
        colcon-mixin-repository: https://raw.githubusercontent.com/colcon/colcon-mixin-repository/3e627e0fa30db85aea05a50e2c61a9832664d236/index.yaml
        package-name: my_package

To look for detected memory errors, check the build logs for entries containing ERROR: AddressSanitizer. Example:

==9442== ERROR: AddressSanitizer heap-use-after-free on address 0x7f7ddab8c084 at pc 0x403c8c bp 0x7fff87fb82d0 sp 0x7fff87fb82c8

ASan is analyzing memory issues at runtime. ASan diagnostic messages will be emitted by the package tests when they run.

Generate, and processing code coverage data

Generate code coverage information using lcov and colcon-lcov-result

If the compiler is invoked with the appropriate flags, action-ros-ci will use colcon-lcov-result to generate coverage information.

Flags can be passed manually using, for instance, extra-cmake-args, but it is preferable to use a colcon mixin to pass the appropriate flags automatically.

    steps:
    - uses: ros-tooling/setup-ros@0.0.19
    - uses: ros-tooling/action-ros-ci@0.0.15
      with:
        package-name: my_package
        colcon-mixin-name: coverage-gcc
        # If possible, pin the repository in the workflow to a specific commit to avoid
        # changes in colcon-mixin-repository from breaking your tests.
        colcon-mixin-repository: https://raw.githubusercontent.com/colcon/colcon-mixin-repository/5c45b95018788deff62202aaa831ad4c20ebe2c6/index.yaml

Integrate action-ros-ci with codecov

The generated code coverage information can be uploaded to codecov.io. In this case, you will need to setup a secret CODECOV_TOKEN in your repository settings.

See action/codecov-action documentation for more information about how to setup the action.

    steps:
    - uses: ros-tooling/setup-ros@0.0.19
    - uses: ros-tooling/action-ros-ci@0.0.15
      with:
        package-name: my_package
        colcon-mixin-name: coverage-gcc
        # If possible, pin the repository in the workflow to a specific commit to avoid
        # changes in colcon-mixin-repository from breaking your tests.
        colcon-mixin-repository: https://raw.githubusercontent.com/colcon/colcon-mixin-repository/5c45b95018788deff62202aaa831ad4c20ebe2c6/index.yaml
    - uses: codecov/codecov-action@v1.0.6
      with:
        token: ${{ secrets.CODECOV_TOKEN }}
        file: ros_ws/lcov/total_coverage.info
        flags: unittests
        name: codecov-umbrella
        yml: ./codecov.yml

You will also need to add a codecov.yaml configuration file:

fixes:
  - "ros_ws/src/my_package/::"

The configuration file is required to let codecov map the workspace directory structure, to the Git repository structure, and setup the links between codecov and GitHub properly.

Store colcon logs as build artifacts

GitHub workflows can persist data generated in workers during the build using artifacts. action-ros-ci generated colcon logs can be saved as follow:

    - uses: ros-tooling/action-ros-ci@0.0.15
      id: action_ros_ci_step
      with:
        package-name: ament_copyright
    - uses: actions/upload-artifact@v1
      with:
        name: colcon-logs
        path: ${{ steps.action_ros_ci_step.outputs.ros-workspace-directory-name }}/log
    - if: always()  # upload the logs even when the build fails
