A lightweight Symfony bundle providing declarative distributed locking based on AOP (Aspect-Oriented Programming). Easily add locking logic to your methods using attributes, enabling safe concurrency control in distributed environments.

Features

Declarative locking with the #[Lockable] attribute
Customizable lock key with Twig template syntax
Automatic lock acquire/release (even on exception)
Seamless integration with Symfony Lock component
Suitable for distributed/multi-instance deployments

Installation

Requirements:

PHP >= 8.1
Symfony >= 6.4
symfony/lock, twig/twig, tourze/symfony-aop-bundle

Install via Composer:

composer require tourze/symfony-aop-lock-bundle

Tourze\Symfony\AopLockBundle\AopLockBundle::class => ['all' => true],

Quick Start

Annotate your methods with #[Lockable]:

use Tourze\Symfony\AopLockBundle\Attribute\Lockable;

class OrderService
{
    #[Lockable]
    public function processOrder(string $orderId): void
    {
        // business logic
    }

    #[Lockable(key: "user_{{ userId }}_update")]
    public function updateUserProfile(int $userId, array $data): void
    {
        // business logic
    }
}

The lock key can be customized using method parameters and Twig syntax, e.g. order_{{ orderId }}.
Supported Twig variables: method parameters, joinPoint.method, joinPoint.class, etc.

Documentation

API Reference
Configuration:
- Default lock timeout: 30 seconds
- All lock/unlock logic is handled automatically by the aspect
Advanced:
- Implement your own lock service by extending the aspect or LockService interface
- Customize lock behavior by overriding LockAspect

Performance & Best Practices

Only use locking where necessary, as it introduces network overhead
Keep lock scope as small as possible
Use fine-grained keys to maximize concurrency
Ensure all nodes have synchronized clocks in distributed setups
Monitor for lock timeouts and failures
