Development

Local Dev

We recommend using the VIP local development environment for local development: https://docs.wpvip.com/technical-references/vip-local-development-environment/

We also have to ensure that we have our dependencies installed - so first, run the following:

git submodule update --init --recursive
composer install
npm install

To use mu-plugins code in a "hot-reload" fashion you need to specify the local folder to which this repository is cloned. For example:

vip dev-env create --mu-plugins $(pwd)

You will be prompted to configure other options of the environment. When the environment is created you can start it with:

vip dev-env start

Tests

PHP Lint

npm run phplint

PHPCS

We use eslines to incrementally scan changed code. It will automatically run on pre-push (see .huskyrc.json).

This is also run on Circle CI for all PRs.

If you want to scan the entire codebase:

npm run phpcs

PHPUnit

If you don't have the Lando-based environment running (e.g. in a CI context), we have a script that runs unit tests in a self-contained Docker environment. To run these tests, execute the following from the project root:

./bin/test.sh

You can also filter by test name.

./bin/test.sh --filter test__rate_limit_ep_query_integration__clears_start_correctly

See ./bin/test.sh for more options.

CI

PHP Linting and PHPUnit tests are run by Circle CI as part of PRs and merges. See .circleci/config.yml for more.

Core tests

We run core tests as part of the CI pipeline. There are many failures when running with mu-plugins so we had to ignore several tests. To add another test there check bin/utils.sh.

To investigate failing test locally you can do following (buckle up as this is not so easy:()):

1. While in your mu-plugins folder do MU_PLUGINS_DIR=$(pwd)

2. Switch to where you want to checkout core code e.g. cd ~/svn/wp

3. Checkout the core code (pick the latest version): svn co --quiet --ignore-externals https://develop.svn.wordpress.org/tags/5.5.3 .

4. Create test config: cp wp-tests-config-sample.php wp-tests-config.php && sed -i 's/youremptytestdbnamehere/wordpress_test/; s/yourusernamehere/root/; s/yourpasswordhere//; s/localhost/127.0.0.1/' wp-tests-config.php

5. Build core npm ci && npm run build

6. Export env variable export WP_TESTS_DIR="$(pwd)/tests/phpunit"

7. Start local DB: docker run -d -p 3306:3306 circleci/mariadb:10.2

8. Create empty DB mysqladmin create wordpress_test --user="root" --password="" --host="127.0.0.1" --protocol=tcp

9. Copy over MU-plugins cp -r $MU_PLUGINS_DIR build/wp-content/mu-plugins

10. Run the test you want (in this case test_allowed_anon_comments) $MU_PLUGINS_DIR/vendor/bin/phpunit --filter test_allowed_anon_comments

Deployment

Release

A new release of the plugin consists of all those pull requests that have been merged since the last release and have been deployed to Staging (i.e. have the [Status] Deployed to staging label. Releases are named after the day they are released plus a minor version:

YYYYMMDD.x

e.g: 20210917.0

Releases are created using GitHub's releases and are effectively a tag in the GitHub repository. Previous releases can be found here.

To create a new production release:

1. Create a new PR: https://github.com/Automattic/vip-go-mu-plugins/compare/production...staging
2. Name it Production release: vYYYYMMDD.0.
3. After carefully reviewing and making sure all test have passed, merge it.
4. The changelog will be generated automatically, and a bot will ping you to proof-read the draft
5. Any follow-up releases on the same day should increment the last number. E.g. Production release: vYYYYMMDD.0

To create a new staging release, follow the same steps but name the release Staging release: vYYYYMMDD.1 (assuming production release has been tagged already.)

Production

For Automattic Use: Instructions are in the FG :)

vip-go-mu-plugins-built

This is a repo primarily meant for local non-development use.

Every commit merged into develop is automatically pushed to the public copy at Automattic/vip-go-mu-plugins-built. This is handled via CI by the deploy action, which pushes a copy of this repo and expanded submodules.

Changelog

We use a script to generate changelog entries. This can be debuged by running:

php ci/changelog-summary.php  --debug --dry-run --force --merge-pr 4673 --github-project-username Automattic --github-project-reponame vip-go-mu-plugins
