- Use object reference comparison first before falling back to ID matching
- Prevent incorrect message index lookup when duplicate IDs exist
- Apply fix to both handleMessageReset and handleMessageDelete functions
- Maintain backward compatibility with ID-based message identification
Previously, when importing messages that contained duplicate IDs, the
findIndex operation would match the first occurrence rather than the
intended message, causing history truncation on retry. This change uses
object reference comparison as the primary method, ensuring accurate
message identification and preserving conversation history.
Update tooltip messages from "正在生成中，请稍候..." to "操作暂时被禁用"
in MessageActions component to better reflect that actions can be disabled
during both message generation and editing states.
Changes:
- Replace specific "generating" message with generic "temporarily disabled" message
- Applies to retry, edit, role toggle, and delete action tooltips
- Provides more accurate user feedback for disabled states
Files modified:
- web/src/components/playground/MessageActions.js
Completely restructured the Playground component from a 1437-line monolith
into a maintainable, modular architecture with 62.4% code reduction (540 lines).
**Key Improvements:**
- **Modular Architecture**: Extracted business logic into separate utility files
- `utils/constants.js` - Centralized constant management
- `utils/messageUtils.js` - Message processing utilities
- `utils/apiUtils.js` - API-related helper functions
- **Custom Hooks**: Created specialized hooks for better state management
- `usePlaygroundState.js` - Centralized state management
- `useMessageActions.js` - Message operation handlers
- `useApiRequest.js` - API request management
- **Code Quality**: Applied SOLID principles and functional programming patterns
- **Performance**: Optimized re-renders with useCallback and proper dependency arrays
- **Maintainability**: Implemented single responsibility principle and separation of concerns
**Technical Achievements:**
- Eliminated code duplication and redundancy
- Replaced magic strings with typed constants
- Extracted complex inline logic into pure functions
- Improved error handling and API response processing
- Enhanced code readability and testability
**Breaking Changes:** None - All existing functionality preserved
This refactor transforms the codebase into enterprise-grade quality following
React best practices and modern development standards.
- Add role toggle button in MessageActions component for assistant/system messages
- Implement handleRoleToggle function in Playground component to switch between assistant and system roles
- Add visual distinction for system messages with orange badge indicator
- Update roleInfo configuration to use consistent avatars for assistant and system roles
- Add proper tooltip texts and visual feedback for role switching
- Ensure role toggle is disabled during message generation to prevent conflicts
This feature allows users to easily switch message roles between assistant and system,
providing better control over conversation flow and message categorization in the playground interface.
