In principle, it can be possible to build an API-compatible version based on the ES CR, by providing a "Node" shim object. Requirements ------------ [](#requirements) ### DB [](#db) The Event Sourced Content Repository relies on a feature called (Recursive) Common Table Expressions (CTE) that require - [MySQL](https://www.mysql.com/why-mysql/presentations/mysql-80-common-table-expressions/): 8.0+ - [MariaDB](https://mariadb.com/kb/en/library/recursive-common-table-expressions-overview/): 10.2.2+ Lateron, we will also support [PostgreSQL](https://www.postgresql.org/docs/8.4/queries-with.html). (We know it will work, but we did not create migrations or did testing yet). ### PHP [](#php) The new code should be compatible with **PHP 7.4** Getting Started / Installation ------------------------------ [](#getting-started--installation) See Linting ------- [](#linting) Linting is done via CodeSniffer and PHPStan. Both are integrated as composer scripts (see composer.json). To manually lint your branch before opening a PR, you can run ``` composer lint ``` from the folder the collection resides (probably `Packages/CR` in a Neos distribution) ### Commit hooks [](#commit-hooks) Linting can be added to commit hooks if desired. In the collection folder (probably `Packages/CR` in a Neos distribution), add lines similar to the following to your `.git/hooks/pre-commit` file (the example is for a DDEV environment): ``` #!/bin/sh ddev exec "cd Packages/CR; composer lint" ``` Road to first running beta -------------------------- [](#road-to-first-running-beta) - create standalone package collection instead of branches - command to import from NodeData to events - make it work with Neos.ContentRepository.DimensionSpace package - ensure Behavioral Tests run again - Update CR for Neos 5 - Update EventSourcedNeosAdjustments for Neos 5 - Content Cache (#103) - ensure Functional Tests run again - figure out how/if to use event sourced Site/Domain (!possibly difficult!) -> fixed; won't use event sourced site/domain - change RoutePart Handler when using event-sourced mode - adjust NodeController when using event-sourced mode - add switch to use event-sourced read model in Fusion rendering (!possibly difficult due to method signatures!) - allow to open User Interface based on Event-Sourced read model - implement Show/Hide of nodes (recursively) - create Commands in response to UI interaction - SetProperty command - CreateNode - MoveNode - ShowNode - DisableNode - create feature list in this README, detailing what is supported and what not yet. - support empty content dimension values in URL; e.g. "/de/..." for german, and "/..." for english - absolute node referencing for ContentCollection (e.g. shared footer in Demo Site) - fix Policy handling to configure permissions for various UI parts - fix structure tree - show correct workspace state after reload (top publish button) - \[?\] fix inline linking - fix node tree search - \[?\] fix node tree filter - Implement Node Repair - (further TODOs here; this list is not complete yet) Development of the Postgres Adapter =================================== [](#development-of-the-postgres-adapter) By default, the Mysql Adapter is active right now, as Postgres is still in development. To activate Postgres, right now, the following steps are needed **in your distribution**: ``` # Configuration/Objects.yaml Neos\EventSourcedContentRepository\Domain\Projection\Content\ContentGraphInterface: className: 'Neos\ContentGraph\PostgreSQLAdapter\Domain\Repository\ContentHypergraph' ``` **if you want to run Postgres and MySQL side by side for the tests, you need the following config:** ``` # Configuration/Settings.yaml Neos: EventSourcedContentRepository: unstableInternalWillChangeLater: testing: projectorsToBeReset: 'Neos\ContentGraph\PostgreSQLAdapter\Domain\Projection\HypergraphProjector': true activeContentGraphs: 'Postgres': 'Neos\ContentGraph\PostgreSQLAdapter\Domain\Repository\ContentHypergraph' projection: defaultProjectorsToBeBlocked: 'Neos\ContentGraph\PostgreSQLAdapter\Domain\Projection\HypergraphProjector': true ``` **if you want to run Postgres without MySQL, you need the following config:** ``` # Configuration/Settings.yaml Neos: EventSourcedContentRepository: unstableInternalWillChangeLater: testing: projectorsToBeReset: 'Neos\ContentGraph\PostgreSQLAdapter\Domain\Projection\HypergraphProjector': true 'Neos\ContentGraph\DoctrineDbalAdapter\Domain\Projection\GraphProjector': false activeContentGraphs: 'Postgres': 'Neos\ContentGraph\PostgreSQLAdapter\Domain\Repository\ContentHypergraph' 'DoctrineDBAL': false projection: defaultProjectorsToBeBlocked: 'Neos\ContentGraph\PostgreSQLAdapter\Domain\Projection\HypergraphProjector': true 'Neos\ContentGraph\DoctrineDbalAdapter\Domain\Projection\GraphProjector': false ``` Technical Description (for developers) ====================================== [](#technical-description-for-developers) This section should give an overview about the different involved packages, to ease understanding the different moving parts. Neos.ContentRepository ---------------------- [](#neoscontentrepository) see [neos/neos-development-collection#2202](https://github.com/neos/neos-development-collection/pull/2202) for the Pull Request. - in namespace `Domain\Projection\Content`, the new `NodeInterface` and `TraversableNodeInterface` are defined. - in namespace `Domain\ValueObject`, corresponding value objects are defined. - the old `Neos\ContentRepository\Domain\Model\Node` implements the full new `NodeInterface` and most of `TraversableNodeInterface`. This is needed to ensure we can build FlowQuery implementations which can work with old and new API at once. - adjusted FlowQuery operations to `TraversableNodeInterface` (TODO not yet all of them) Neos.Neos --------- [](#neosneos) see [neos/neos-development-collection#2202](https://github.com/neos/neos-development-collection/pull/2202) for the Pull Request. - various detail improvements to use `TraversableNodeInterface` in the core (e.g. FusionView) Neos.ContentRepository.DimensionSpace ------------------------------------- [](#neoscontentrepositorydimensionspace) APIs to query the configured dimension space CR / Neos.EventSourcedContentRepository --------------------------------------- [](#cr--neoseventsourcedcontentrepository) Transition package implementing the event sourced CR core. In the longer run, will probably be merged into Neos.ContentRepository. - `Domain\Context\*` implements Commands, Command Handlers, Events for Workspace, Content Stream, Nodes - `Domain\Projection\*` implements projections for changes, workspace listing; and contains the definition for the main `Content` Graph projection (`ContentGraphInterface` and `ContentSubgraphInterface`) CR / Neos.ContentGraph.DoctrineDbalAdapter ------------------------------------------ [](#cr--neoscontentgraphdoctrinedbaladapter) implementation of the `ContentGraphInterface` and `ContentSubgraphInterface` using MySQL queries. CR / Neos.ContentGraph.PostgreSQLAdapter ---------------------------------------- [](#cr--neoscontentgraphpostgresqladapter) implementation of the `ContentGraphInterface` and `ContentSubgraphInterface` using PostgreSQL queries. CR / Neos.EventSourcedNeosAdjustments ------------------------------------- [](#cr--neoseventsourcedneosadjustments) It turns out that there are numerous changes needed to the details of Neos.Neos - so this package hooks into various places in the Neos lifecycle to override certain Neos functionality. We often completely override certain classes / behaviors from the Neos core completely; so that should make merging the changes back to the Neos.Neos package at some point a lot easier because we can then replace full classes instead of only individual pieces. This package consists of the following bounded contexts, listed in their order during request processing: ### NodeImportFromLegacyCR [](#nodeimportfromlegacycr) This contains a CommandController and a service to generate events from reading `NodeData`. It can be activated using the new CLI command. ### EventSourcedRouting [](#eventsourcedrouting) We replace the default `FrontendNodeRoutePartHandler` by providing an extra implementation of `FrontendNodeRoutePartHandlerInterface`. **Activation**: We replace the implementation of `FrontendNodeRoutePartHandlerInterface` in `Objects.yaml`. - internally, the `Http` and `Routing` namespaces are used for behaviours internal to the routing. ### EventSourcedFrontController [](#eventsourcedfrontcontroller) This is a replacement for `Frontend\NodeController` of Neos.Neos. **Activation**: We trigger this controller by AOP (in `NodeControllerAspect`): We call the new controller when `processRequest()` is called for the Neos controller. ### Fusion [](#fusion) - We replace certain Fusion implementations which are already re-implemented to work more efficiently with the ContentGraph API; and which implement linking (because this API also changed). This includes: - `Menu / DimensionMenu` - `NodeUri, ConvertUris` - `ContentElementEditable / ContentElementWrapping` (because the ContentElementWrapping service has changed quite a lot) - **Activation**: using fusion `autoInclude` in `Settings.yaml`, we load the Fusion file `resource://Neos.EventSourcedNeosAdjustments/Private/Fusion/Root.fusion`. This `Root.fusion` *replaces the implementations* for the aforementioned Fusion objects, so things work as expected for integrators (without new namespaces). - Eel `NodeHelper` and `WorkspaceHelper` - **Activation**: These helpers are registered under the names `Neos.EventSourcedNeosAdjustments.*`; so a separate name. These helpers are explicitely used in the `Root.fusion` mentioned a few lines above. - custom `ExceptionHandler` because this also needs the replacement `ContentElementWrappingService`. - **Activation**: This helper is used as exception handlers in the `Root.fusion` mentioned a few lines above. - If people used these exception handlers themselves, they need to reconfigure them to the new implementations. ### Fluid [](#fluid) - We replace Linking and Content Element Wrapping ViewHelpers, because Node Linking has changed and ContentElementWrapping has changed as well. - **Activation**: Using AOP, the `ViewHelperReplacementAspect` implements aliasing of ViewHelper classes; effectively returning the VHs in this namespace instead of the default ones. ### ContentElementWrapping [](#contentelementwrapping) We implement a completely new `ContentElementWrappingService` and `ContentElementWrappingService`; mainly because they change quite a bit and their interfaces now require `TraversableNodeInterface` instead of the legacy `NodeInterface`. The new services are used in the overridden ViewHelpers (see section *Fluid* above); and in overridden Fusion implementations (see section *Fusion* above). ### NodeAddress (Domain\\Context\\Content) [](#nodeaddress-domaincontextcontent) A `NodeAddress` is an external representation of a node (used in routing). TODO: Move to Neos.EventSourcedContentRepository. ### Ui [](#ui) - `BackendController` is an alternative implementation for `Neos.Neos.Ui` `BackendController`. - **Activation**: We trigger this controller by AOP (in `BackendControllerAspect`): We call the new controller when `processRequest()` is called for the Neos backend controller. - We create Content Streams on backend login using the `EditorContentStreamZookeeper` (TODO change name maybe?). - **Activation**: We trigger this service by Signal/Slot in `Package.php`. - `Fusion` (for backend) - **Activation**: We load a custom `resource://Neos.EventSourcedNeosAdjustments/Private/Fusion/Backend/Root.fusion` using `Views.yaml`. - custom `NodeInfoHelper`, calling to a custom `NodePropertyConverterService` - adjust the *DimensionSwitcher* JS component in `Resources/Private/UiAdapter` - TODO: this is not everything yet. ### Health Score 23 — LowBetter than 27% of packages Maintenance0 Infrequent updates — may be unmaintained Popularity16 Limited adoption so far Community19 Small or concentrated contributor base Maturity50 Maturing project, gaining track record Bus Factor1 Top contributor holds 75.4% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
