This commit introduces several architectural improvements and optimizations across the codebase:
- **Performance & Reliability**:
- Implemented Redis pipelining in `ConversationCache.CacheMessage` to reduce network round-trips.
- Added a circuit breaker to the JPush client to prevent cascading failures.
- Introduced batch deletion and batch member addition capabilities in repositories.
- Added message idempotency support using `client_msg_id` and a Redis-based cache.
- Optimized WebSocket handling with connection limits (total and per-user) and improved error logging.
- **Code Refactoring**:
- Refactored `Router` to use a `RouterDeps` struct, simplifying the constructor and improving maintainability.
- Unified model ID generation logic using new `id_helper.go` (supporting UUID and Snowflake).
- Standardized JSON serialization/deserialization in models using `json_helper.go`.
- Refactored DTO conversion logic, specifically for `UserResponse` (using functional options) and `Report` responses.
- Removed redundant/deprecated DTOs like `PostDetailResponse` and `TradeItemDetailResponse`.
- **Cache Improvements**:
- Enhanced `LayeredCache` with `SetRaw` to avoid double-encoding when promoting values from Redis to local cache.
- Added `DeleteBatch` support to the cache interface.
- **Other Changes**:
- Cleaned up `config.go` by removing redundant default values and explicit environment variable overrides.
- Improved WebSocket registration flow to handle connection limits gracefully.
Add rich message segment support enabling structured content (text, images, votes, mentions) in posts and comments. Includes segments field in models, DTOs, handlers, and services. Also adds @mention notification processing and migrates vote data to embedded segments.
Implement sensitive word filtering feature with configurable database and Redis
support. Add security enhancements including WebSocket origin validation, improved
password strength requirements, timing attack prevention, and production JWT secret
validation. Add batch operation validation limits and optimize user blocking
queries with subqueries.
BREAKING CHANGE: Password validation now requires minimum 8 characters with uppercase,
lowercase, and digit (was 6-50 characters without complexity requirements)
- Added Channel support in Post model, including ChannelID field in PostRequest and PostResponse DTOs.
- Updated PostService and PostRepository to handle channel-specific logic for creating and listing posts.
- Introduced ChannelRepository and ChannelService, along with corresponding handlers for managing channels.
- Enhanced router to include routes for channel management and public channel listing.
- Seeded default channels in the database during initialization.
- Removed Gorse-related configurations, handlers, and dependencies from the codebase.
- Introduced HotRank feature with configuration options for ranking posts based on recent activity.
- Updated application structure to support HotRank processing, including new caching mechanisms and database interactions.
- Cleaned up related DTOs and repository methods to reflect the removal of Gorse and the addition of HotRank functionality.
- Added NODE_NO_WARNINGS environment variable to build and deploy workflows.
- Upgraded actions/upload-artifact and actions/download-artifact to version 4 in the build workflow.
- Introduced ContentEditedAt field in PostResponse and PostDetailResponse DTOs to track content modification timestamps.
- Updated post conversion functions to include ContentEditedAt in responses.
- Ensured ContentEditedAt is set during post updates in the repository.
- Add admin handlers and services for users, posts, comments, groups, and dashboard
- Implement role permission management with ability to view and update permissions
- Add database seeding for roles and Casbin permission policies
- Upgrade Casbin from v2 to v3 with GORM adapter for persistent policy storage
- Add admin-specific repository methods with filtering and pagination
- Register new admin API routes under /api/v1/admin/*
