Optimistic Entity Lock Bundle

The CoreShop Optimistic Entity Lock Bundle is a specialized package for the CoreShop e-commerce framework, designed for handling optimistic entity locking on the Pimcore platform. This bundle is crucial for preventing editing conflicts when multiple users attempt to modify the same entity simultaneously.

Installation Process​

To install the Optimistic Entity Lock Bundle, use Composer:

$ composer require coreshop/optimistic-entity-lock-bundle:^4.0

Integrating with the Kernel​

Enable the bundle in the kernel by updating the AppKernel.php file:

<?php

// app/AppKernel.php

public function registerBundlesToCollection(BundleCollection $collection)
{
    $collection->addBundles([
        new \CoreShop\Bundle\OptimisticEntityLockBundle\CoreShopOptimisticEntityLockBundle(),
    ]);
}

Usage Instructions​

Implementing the Interface​

Your Pimcore DataObject Class needs to implement the CoreShop\Bundle\OptimisticEntityLockBundle\Model\OptimisticLockedInterface.

Adding the Field to Class Definition​

Add the field optimisticLockVersion to your Pimcore Class Definition. This field is pivotal for the locking mechanism.

Functionality​

Once implemented, every time the DataObject is saved, CoreShop checks and increments the version number. If the version differs from the last saved state (indicating another user has saved changes), an exception is thrown, preventing overwrite conflicts.

This bundle ensures data integrity and consistency in scenarios where concurrent editing might occur, safeguarding your e-commerce data against inadvertent overwrites.
