This commit introduces a comprehensive refactoring of the event-store module to guarantee data consistency and improve the quality and reliability of its test suite.
Data Consistency
Implemented Redis transactions (MULTI/EXEC) for the appendToStream operation in RedisEventStore.
This ensures that writing an event to the aggregate-specific stream and the global "all-events" stream is an atomic operation, preventing data inconsistencies in case of partial failures.
Improved error handling by invalidating the local stream version cache on transactional failures.
Testing Enhancements
Refactored Consumer Tests: Replaced the asynchronous, thread-based consumer test in RedisIntegrationTest with a synchronous, deterministic approach. The test now manually calls pollEvents() to verify event consumption, making it faster and 100% reliable by removing Thread.sleep and CountDownLatch.
Simplified Test Events: Reduced boilerplate code in test event data classes (TestCreatedEvent, TestUpdatedEvent) in both RedisEventStoreTest and RedisIntegrationTest by using the @Transient annotation on overridden properties from BaseDomainEvent.
Fixed Compilation Errors: Resolved various compilation errors in the test suite that arose from refactoring and incorrect mock definitions.
This commit introduces a major refactoring of the build system and the core infrastructure modules. The primary goal is to establish a strict "Single Source of Truth" for all dependencies using Gradle Version Catalogs and to create a clean, maintainable, and scalable foundation for all current and future services.
### 1. Centralized Dependency Management (`libs.versions.toml`)
- **Established Single Source of Truth:** All dependency versions are now exclusively managed in `gradle/libs.versions.toml`. Hardcoded versions have been removed from all build scripts.
- **Introduced Gradle Bundles:** To simplify module dependencies, several bundles have been created (e.g., `testing-jvm`, `redis-cache`, `spring-cloud-gateway`, `monitoring-client`). This drastically reduces boilerplate in the `build.gradle.kts` files and improves readability.
- **Cleaned up Aliases:** All library and plugin aliases have been standardized for consistency.
### 2. Infrastructure Module Refactoring
All infrastructure modules (`core`, `platform`, `auth`, `cache`, `event-store`, `messaging`, `monitoring`, `gateway`) have been refactored to align with the new dependency management strategy.
- **Simplified Build Scripts:** The `build.gradle.kts` for each module now uses the new bundles and aliases, making them significantly cleaner and easier to understand.
- **Consistent Structure:** The architecture of each module now clearly follows the Port-Adapter pattern where applicable (e.g., `cache-api`/`redis-cache`).
- **Standardized `platform-bom`:** The project's own Bill of Materials (`platform-bom`) now also includes the Spring Cloud BOM, ensuring version consistency for all Spring-related dependencies.
### 3. Added Infrastructure Documentation
To improve onboarding and architectural understanding, a dedicated `README-*.md` file has been created for each refactored infrastructure module:
- `README-CORE.md`
- `README-PLATFORM.md`
- `README-INFRA-AUTH.md`
- `README-INFRA-CACHE.md`
- `README-INFRA-EVENT-STORE.md`
- `README-INFRA-MESSAGING.md`
- `README-INFRA-MONITORING.md`
- `README-INFRA-GATEWAY.md`
These documents explain the purpose, architecture, and usage of each component within the system. This lays the groundwork for our "Tracer Bullet" development approach.
