Neos development collection

FOR DOCS ON THE EVENT SOURCED CONTENT REPOSITORY, READ ON BELOW

This repository is a collection of packages for the Neos content application platform (learn more on https://www.neos.io/). The repository is used for development and all pull requests should go into it.

If you want to install Neos, please have a look at the documentation: https://neos.readthedocs.org/en/latest/

Contributing

If you want to contribute to Neos and want to set up a development environment, then follow these steps:

composer create-project neos/neos-development-distribution neos-development 8.3.x-dev --keep-vcs

Note the -distribution repository you create a project from, instead of just checking out this repository.

If you need a different branch, you can either use it from the start (replace the 8.3.x-dev by 9.0.x-dev or whatever you need), or switch after checkout (just make sure to run composer update afterwards to get matching dependencies installed.) In a nutshell, to switch the branch you intend to work on, run:

git checkout 9.0 && composer update

The code of the CMS can then be found inside Packages/Neos, which itself is the neos-development-collection Git repository. You commit changes and create pull requests from this repository.

In the root directory of the development distribution, you can do the following things:

To run tests, run ./bin/phpunit -c ./Build/BuildEssentials/PhpUnit/UnitTests.xml for unit tests or ./bin/phpunit -c ./Build/BuildEssentials/PhpUnit/FunctionalTests.xml for functional/integration tests.

Note

We use an upmerging strategy: create all bugfixes to the lowest maintained branch that contains the issue. Typically, this is the second last LTS release - see the diagram at https://www.neos.io/features/release-process.html.

For new features, pull requests should be made against the branch for the next minor version (named like x.y). Breaking changes must only go into the branch for the next major version.

For more detailed information, see https://discuss.neos.io/t/development-setup/504, https://discuss.neos.io/t/creating-a-pull-request/506 and https://discuss.neos.io/t/git-branch-handling-in-the-neos-project/6013

New (Event Sourced) Content Repository (ES CR)

Prerequisites

  • You need PHP 8.2 installed.
  • You need a recent MySQL/MariaDB (PostgreSQL ist not yet supported)
  • Please be sure to run off the Neos-Development-Distribution in Branch 9.0, to avoid dependency issues (as described above).

Setup

The ES CR has a Docker-compose file included in Neos.ContentRepository.BehavioralTests which starts both Mariadb and Postgres in compatible versions. Additionally, there exists a helper to change the configuration in your distribution (/Configuration) to the correct values matching this database.

Do the following for setting up everything:

  1. Start the databases:

    pushd Packages/Neos/Neos.ContentRepository.BehavioralTests; docker compose up -d; popd

# to stop the databases:
pushd Packages/Neos/Neos.ContentRepository.BehavioralTests; docker compose down; popd
# to stop the databases AND remove the stored data:
pushd Packages/Neos/Neos.ContentRepository.BehavioralTests; docker compose down -v; popd

  2. Copy matching Configuration:

    cp -R Packages/Neos/Neos.ContentRepository.BehavioralTests/DistributionConfigurationTemplate/* Configuration/

  3. Run Doctrine Migrations:

    ./flow doctrine:migrate
FLOW_CONTEXT=Testing/Postgres ./flow doctrine:migrate

  4. Setup the Content Repository

    ./flow cr:setup

  5. Set up Behat

    cp -R Packages/Neos/Neos.ContentRepository.BehavioralTests/DistributionBehatTemplate/ Build/Behat
pushd Build/Behat/
rm composer.lock
composer install
popd

Site Setup

You can chose from one of the following options:

Creating a new Site

./flow site:create neosdemo Neos.Demo Neos.Demo:Document.Homepage

Migrating an existing (Neos < 9.0) Site

# WORKAROUND: for now, you still need to create a site (which must match the root node name)
# !! in the future, you would want to import *INTO* a given site (and replace its root node)
./flow site:create neosdemo Neos.Demo Neos.Demo:Document.Homepage

# the following config points to a Neos 8.0 database (adjust to your needs), created by
# the legacy "./flow site:import Neos.Demo" command.
./flow cr:migrateLegacyData --config '{"dbal": {"dbname": "neos80"}, "resourcesPath": "/path/to/neos-8.0/Data/Persistent/Resources"}'

# TODO: this JSON config is hard to write - we should change this soonish.

Importing an existing (Neos >= 9.0) Site from an Export

# import the event stream from the Neos.Demo package
./flow cr:import Packages/Sites/Neos.Demo/Resources/Private/Content

Running Neos

./flow server:run

Running the Tests

The normal mode is running PHP locally, but running Mariadb / Postgres in containers (so we know we use the right versions etc).

cd Packages/Neos
composer test:behavioral

Running all tests can take a long time, depending on the hardware. To speed up the process, Behat tests can be executed in a "synchronous" mode:

composer test:behavioral:sync

Alternatively, if you want to reproduce errors as they happen inside the CI system, but you develop on Mac OS, you might want to run the Behat tests in a Docker container (= a linux environment) as well. We have seen cases where they behave differently, i.e. where they run without race conditions on OSX, but with race conditions in Linux/Docker. Additionally, the Linux/Docker setup described below also makes it easy to run the race-condition-detector:

docker compose --project-directory . --file Packages/Neos/Neos.ContentRepository.BehavioralTests/docker-compose-full.yml build
docker compose --project-directory . --file Packages/Neos/Neos.ContentRepository.BehavioralTests/docker-compose-full.yml up -d
docker compose --project-directory . --file Packages/Neos/Neos.ContentRepository.BehavioralTests/docker-compose-full.yml run neos /bin/bash

# the following commands now run INSIDE the Neos docker container:
FLOW_CONTEXT=Testing/Behat ../../../../../flow raceConditionTracker:reset

../../../../../bin/behat -c behat.yml.dist

FLOW_CONTEXT=Testing/Behat ../../../../../flow raceConditionTracker:analyzeTrace
