This commit performs a significant cleanup of the codebase by removing unused functions, methods, and entire files across various internal modules. This reduces technical debt and simplifies the project structure.
Key changes include:
- **cache**: Removed unused cache key generators and metrics snapshots.
- **dto**: Removed redundant converter functions and segment creation helpers.
- **middleware**: Deleted the unused `logger.go` middleware and simplified `ratelimit.go` and `casbin.go`.
- **model**: Removed unused ID helpers, database closing functions, and batch decryption logic.
- **pkg**: Cleaned up unused utility functions in `circuitbreaker`, `crypto`, `cursor`, `hook`, and `utils`.
- **service**: Deleted `account_cleanup_service.go` and removed unused helper functions in `log_cleanup_service.go` and `sensitive_service.go`.
- **repository**: Removed unused private loading methods in `comment_repo.go`.
Add Tencent Cloud Text Moderation System (TMS) as a fallback moderation
service when OpenAI is unavailable or returns an error. The service
now checks OpenAI first, and falls back to Tencent TMS if it fails,
providing better reliability for content moderation.
Features:
- New Tencent TMS configuration in config.yaml with environment variable overrides
- New tencent package in internal/pkg/tencent/ with TMS client implementation
- PostAIService now uses dual moderation with OpenAI primary and Tencent fallback
- Strict mode configuration passed to PostAIService for consistent behavior
BREAKING CHANGE: NewPostAIService now requires tencentClient and strictMode
parameters - update wire configuration accordingly.
