FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package lock-service-bundle
Lock Service Bundle
中文
A flexible distributed lock service bundle for Symfony, supporting Redis Cluster, database, and file-based backends. Ideal for resource mutual exclusion and synchronization in high concurrency scenarios.
Features
- Supports Redis Cluster, database, and file lock backends
- SmartLockStore for automatic backend switching
- Provides read/write locks, blocking locks, and multi-resource locking
- Seamless integration with Symfony ecosystem
- Easy to extend and customize
Requirements
- PHP >= 8.1
- Symfony >= 6.4
- Redis, database, or file backend configured
Installation
Composer
Quick Start
Configuration
Bundle Registration
Add to your bundles.php:
Environment Configuration
Select lock type via APP_LOCK_TYPE environment variable:
- redis
- redis-cluster
- dbal
- flock
Example:
Database Configuration
If using DBAL backend, the bundle automatically configures a dedicated lock
connection with SQLite for testing. For production, configure your database
connection in doctrine.yaml:
Advanced Usage
- Automatic backend switching via SmartLockStore
- Retry and wait mechanism for lock acquisition
- Read/write lock support (see RedisClusterStore)
- Extensible: implement
LockEntityinterface for custom lock resources
Entity Design
This bundle provides a LockEntity interface for defining lock resources:
Implement this interface for your business entities to enable fine-grained distributed locking.
Security
This bundle provides secure distributed locking mechanisms:
- Thread-safe lock acquisition and release
- Automatic lock expiration to prevent deadlocks
- Resource isolation through unique lock keys
- Protection against race conditions in concurrent environments
Security Considerations
- Use unique, unpredictable lock keys for sensitive resources
- Set appropriate lock timeouts to prevent resource starvation
- Monitor lock usage to detect potential abuse
- Use dedicated Redis/database instances for production environments
