Boost.CI

This repository contains scripts that enable continuous integration with Appveyor, Azure Pipelines, codecov.io, Coverity Scan, GitHub Actions, Drone, and Travis CI. These scripts are intended to be downloaded and used during boost repository builds to improve project quality. In most cases the scripts are self-configuring. Some integrations require additional setup actions to complete.

Boost.CI also allows you to run a big-endian build on Travis CI.

Summary (TL;DR)

Here are all the steps you need to take as a Boost repository maintainer to enable all of these CI features in your repository:

1. Checkout develop and then make a new branch called ci.
2. Copy the .appveyor.yml file from this repository into the top level of your repository.
3. Copy the .azure-pipelines.yml file from this repository into the top level of your repository.
4. Copy the .travis.yml file from this repository into the top level of your repository.
5. Copy the .github/workflows/ci.yml file from this repository into the the same folder in your repository.
6. Copy the .drone.star file and .drone directory from this repository to the top level of your repository.
7. Copy the .codecov.yml file from this repository to the top level of your repository and edit if required.
8. Copy the LICENSE file from this repository to the top level of your repository. This adds the BSL-1.0 designation to your repository on github.
9. [optional] Copy the README.template.md file from this repository to the top level README.md of your repository. If you already have a README.md then you can take what you need from the template version to improve it, if desired. Otherwise, you will need to customize README.md for your repository. One useful step is to fixup the repository name using the command sed -i 's/template/<myrepositoryname>/g' README.md, and then update the first line description.
10. In Appveyor, add a project for your fork of the repository. No customization is needed.
11. In Travis CI, add a project for your fork of the repository. Later you will customize it for Coverity Scan, but for now no settings changes are necessary.
12. Commit these changes and push to your personal fork in the ci branch.
13. Create a pull request in your fork of /ci to /develop. Do not target boostorg/develop.
14. Observe that both Appveyor and Travis CI are running the build jobs. Fix up any issues found. Note this may uncover defects in your repository code.
15. If you are the owner or an admin for your repository, add projects in Appveyor and Travis CI for the boostorg/ project (not your fork). If you are just a contributor in the repository, create an issue in Boost.Admin requesting Appveyor and Travis CI to be enabled for the repository.
16. Commit the changes to develop. This will kick off a build on Appveyor and Travis.
17. Update the badge matrix in README.md with the correct links for your Appveyor and Travis CI projects.
18. Create a Coverity Scan account if you have not already done so.
19. Create a new Coverity Scan github based project for your official boostorg repository.
20. Update your Travis CI boostorg repository project settings and add the following environment variables using the Travis CI GUI:
    • COVERITY_SCAN_NOTIFICATION_EMAIL can be public and set to your email account (or it can be private).
    • COVERITY_SCAN_TOKEN should be kept private and set to the scan token you can find in the project settings in Coverity Scan.
21. Update the README.md to put the correct Coverity Scan badge project number into the badge URLs.
22. This will kick off a build on the develop branch that will include Coverity Scan results.
23. To activate Drone, visit https://drone.cpp.al. Authorize Drone: Click the "Authorize cppalliance-drone" button. Sync repositories: Click the "sync" button. A list of repositories will appear. For the relevant repo, click and then choose "Activate Repository". In the settings page, change Configuration from .drone.yml to .drone.star. "Save".
24. More pointers about Drone:
    • Ensure that shell scripts are executable: chmod 755 .drone/drone.sh
    • "asan" jobs require elevated privileges. Contact an administrator or open an issue at drone-ci to set your drone repository to "Trusted".
    • If not using asan, simply remove the jobs.
    • Further info available at https://github.com/CPPAlliance/drone-ci

Repositories using Boost.CI

The CMT Stale Repo Tracker identifies many repositories using Boost.CI and the CMT Status Spreadsheet shows the current state of each. There may be additional repositories using Boost.CI that are not listed. Boost.CI does not track usage internally.

How It Works

The files .appveyor.yml, .azure-pipeline.yml and .travis.yml must exist in your repository and will contain your customizations for build types, languages, and platforms. The templates provided will get you started with the build jobs listed below.

These scripts will copy resources from the Boost.CI repository when needed in order to provide scripting necessary to run all these jobs successfully.

Build jobs that will severely impact performance (such as valgrind) will define BOOST_NO_STRESS_TEST so those can be skipped or hobbled.

Topic Branch Support

The configuration for Travis CI and Appveyor allow for automated branch builds on branch pushes matching these names:

• master
• develop
• bugfix/*
• feature/*
• fix/*
• pr/*

Defaults, Builds and Services

By default all of the builds target C++11 unless otherwise specified. To see what kind of coverage these builds provide, see some build results:

AppVeyor : https://ci.appveyor.com/project/jeking3/uuid-gaamf/builds/19987101
Travis CI: https://travis-ci.org/boostorg/uuid/builds/449557162

Without any customization the scripts can provide the following services (example, see the actual CI scripts for current configurations):
