Exponential Platform Legacy v5.0.2

The definitive stable release of the v5 series — featuring the complete Legacy Bridge integration running on Symfony 7.4 LTS, full Ibexa DXP 5 namespace compatibility, Twig service public visibility fix, and a leaner composer dependency graph.

What Is This?

Exponential Platform Legacy v5 is the open-source DXP skeleton that ships the complete eZ Publish legacy kernel running inside Symfony 7.4 LTS via the se7enxweb/legacy-bridge package — active by default, zero post-install setup required. You get:

• A fully working classic legacy site at /legacy_site/
• A fully working classic legacy admin at /legacy_admin/
• The modern Platform v5 Admin UI at /adminui/
• REST API v2 and GraphQL on Symfony 7.4 LTS
• Multi-database legacy kernel support (MySQL 8.0, MariaDB 10.6, PostgreSQL 14+, SQLite 3.35+) via the sevenx_exponential_platform_v5_database_translator extension

🗄️ Major New Capability: SQLite Support (Zero-Config Local Development)

For the first time in the platform's history, the legacy kernel runs on SQLite 3.35+ with no database server required.

This is a significant quality-of-life improvement for every developer who wants to spin up a local Exponential Platform Legacy site — no MySQL, no MariaDB, no PostgreSQL server to install, configure, or manage. SQLite works out of the box on every macOS, Linux, and Windows (WSL) development machine.

What SQLite support means in practice

# Start a fully working Platform v5 + Legacy Bridge site in under 5 minutes
composer create-project se7enxweb/exponential-platform-legacy my-project
cd my-project

# .env.local — two lines, no database server needed:
echo 'DATABASE_URL="sqlite:///%kernel.project_dir%/var/data_dev.db"' >> .env.local
echo 'MESSENGER_TRANSPORT_DSN=sync://' >> .env.local

# Install — creates the .db file automatically, imports all demo content:
php bin/console exponential:install exponential-oss

When to use SQLite

Bug Fixes

se7enxweb/ngsymfonytools v5.0 branch — Ibexa 5 Namespace Compatibility

Error fixed: NgSymfonyToolsApiContentConverter::__construct(): Argument #1 must be of type eZ\Publish\API\Repository\Repository, Ibexa\Core\Repository\SiteAccessAware\Repository given.

Ibexa DXP 5 moved the Repository interface from the eZ namespace to Ibexa\Contracts\Core\Repository. The legacy extension type-hinted against the old interface, causing a fatal TypeError at runtime.

Fix: A class_alias shim at the top of ngsymfonytoolsapicontentconverter.php maps the old interface to the new one when running under Ibexa 5:

if ( interface_exists( 'Ibexa\Contracts\Core\Repository\Repository', true )
    && !interface_exists( 'eZ\Publish\API\Repository\Repository', true ) )
{
    class_alias( 'Ibexa\Contracts\Core\Repository\Repository', 'eZ\Publish\API\Repository\Repository' );
}

se7enxweb/legacy-bridge v5.0.9 — Twig Service Visibility Fix

Error fixed: ServiceNotFoundException: The "twig" service or alias has been removed or inlined when the container was compiled.

In Symfony 5+, services default to private and are compiled into $container->privates[]. The legacy extension (NgSymfonyToolsIncludeOperator) called $container->get('twig') at runtime which only checks $container->services[], causing a fatal exception on any page rendering a symfony_include legacy template tag.

Fix: TwigPass.php in se7enxweb/legacy-bridge now calls ->setPublic(true) on the twig service definition during container compilation, making it accessible from legacy code.

Composer Dependency Graph Cleanup
