This commit establishes the structural foundation and required infrastructure to support the upcoming compact tool output changes. It includes identity management improvements, layout fixes, and type-safety enhancements that stand independently.
1. Identity & History Management:
- useHistoryManager: Ensure strictly increasing IDs for history items, even with identical timestamps.
- acpClient: Introduced callIdCounter to prevent callId collisions during rapid execution.
- MainContent: Implemented negative ID logic for pending items to ensure stable React keys and prevent collisions.
- historyUtils: New file containing extracted history logic (isToolExecuting, getAllToolCalls) hoisted from AppContainer.
2. UI Infrastructure & Layout:
- test-utils/render: Modernized renderWithProviders and removed legacy props.
- AskUserDialog: Fixed layout, scroll visibility, and alignment issues.
- toolLayoutUtils: Increased TOOL_RESULT_STANDARD_RESERVED_LINE_COUNT for better spacing.
- ShellToolMessage/ToolGroupMessage: Updated line-count expectations and snapshots to align with layout changes.
3. IDE & Diffing Improvements:
- ToolActionsContext: Refactored IdeClient initialization to fix a race condition and potential memory leak.
- edit/diffOptions: Improved accuracy of diff stat derivation, ensuring "full content" stats are available for the model.
- coreToolScheduler: Automatically derive diff stats from patches if missing.
- state-manager: Ensure diffStat preservation for rejected tool calls.
4. Type Safety & Constants:
- types/tools: Added foundational types like DiffStat, FileDiff, and StructuredToolResult.
- Type Guards: Added guards for isFileDiff, isTodoList, isAnsiOutput, and hasSummary.
- CodeColorizer: Added function overloads to gracefully handle null language detection.
- tool-names: Introduced DISPLAY_NAME constants for consistent tool labeling.
This commit passes all workspace tests and builds successfully. Feature-specific logic for compact output is excluded.
