Fix VS Code Extension Setup Failure - Missing README.md and Setup/Ingestion Synchronization

[rysweet]

Summary

This PR comprehensively fixes the VS Code extension setup failure described in Issue #50, addressing both the immediate FileNotFoundError and the underlying setup/ingestion synchronization problems that prevent the extension from working properly on first installation.

Root Cause Analysis

1. Missing README.md Issue: The bundled pyproject.toml references readme = "README.md" but the README.md file was never copied during the bundling process, causing pip install -e . to fail with FileNotFoundError.

2. Setup/Ingestion Race Condition: The extension allows users to trigger workspace ingestion before Python environment setup completes, leading to "Blarify integration not initialized" errors.

Key Changes

1. README.md Bundling Fix

• Updated bundle-blarify.sh: Added logic to copy README.md from parent directory or create a minimal version if missing
• Enhanced setup.py: Added error handling with auto-recovery that creates README.md if pip install fails due to missing file
• Created bundled/README.md: Immediate fix for current bundled version

2. Setup/Ingestion Synchronization

• Enhanced Extension Activation: Added proper setup state tracking with setupState.isSetupComplete
• Ingestion Command Guard: Modified ingestWorkspace command to wait for setup completion with progress indication and 5-minute timeout
• Setup Task Integration: Made Python environment setup part of the main setup flow in runSetupTasks()

3. Comprehensive Error Handling

• PythonEnvironment Retry Logic: Added retry mechanism (up to 2 retries) for transient setup failures
• User-Friendly Error Messages: Enhanced error messages for common issues (missing Python, network problems, permissions)
• Graceful Degradation: Setup failures don't crash the extension, allowing manual retry

4. Comprehensive Testing

• New Test Suite: Created extension-setup.test.ts with 17 tests covering:
  • Bundled files validation (README.md, pyproject.toml, setup.py, etc.)
  • PythonEnvironment setup flow
  • BlarifyIntegration initialization
  • Extension activation and command registration
  • Error handling scenarios
  • Setup synchronization

5. Enhanced Documentation

• Updated EXTENSION-TROUBLESHOOTING.md: Added comprehensive section on setup and bundling issues
• Enhanced Testing Checklist: Added setup validation steps and bundled file verification

Test Results

All tests pass successfully:

• ✅ 48 passing tests (including all new setup tests)
• ✅ Bundled files validation: README.md, pyproject.toml reference satisfaction confirmed
• ✅ Setup flow integration: Extension activation and command registration work
• ✅ Error handling: Graceful handling of missing files and setup failures
• ✅ Synchronization: Analysis waits for setup completion properly

Files Changed

• vscode-blarify-visualizer/scripts/bundle-blarify.sh - README.md bundling logic
• vscode-blarify-visualizer/bundled/setup.py - Enhanced error handling
• vscode-blarify-visualizer/bundled/README.md - Created missing file
• vscode-blarify-visualizer/src/extension.ts - Setup synchronization
• vscode-blarify-visualizer/src/pythonEnvironment.ts - Retry logic and error handling
• vscode-blarify-visualizer/src/test/suite/extension-setup.test.ts - Comprehensive test suite
• vscode-blarify-visualizer/EXTENSION-TROUBLESHOOTING.md - Documentation updates
• .github/Memory.md - Project memory update

Acceptance Criteria Verification

• ✅ Extension setup completes successfully without FileNotFoundError
• ✅ All required files are properly bundled with the extension
• ✅ Ingestion only starts after successful setup completion
• ✅ Proper error handling and user feedback if setup fails
• ✅ Extension can be installed and activated without errors

Impact

This fix resolves a critical usability issue where the Blarify VS Code extension was completely non-functional for new users due to setup failures. The comprehensive approach ensures both immediate fixes and long-term robustness through better error handling and testing.

Testing Instructions

1. Package the extension: npm run package
2. Install in VS Code: code --install-extension blarify-visualizer-0.1.0.vsix --force
3. Activate extension in a new workspace
4. Verify setup completes without errors in Output panel
5. Try workspace ingestion - should wait for setup completion
6. Run test suite: npm test - all tests should pass

Fixes #50

• Excellent Documentation: Comprehensive updates to EXTENSION-TROUBLESHOOTING.md with specific setup and bundling guidance

Technical Implementation Quality ⚡

Bundling Infrastructure (bundle-blarify.sh)

• Smart README.md Handling: Creates bundled README.md from parent or generates minimal version - solves the pyproject.toml reference issue
• Fallback Requirements: Graceful fallback for requirements.txt generation when poetry export fails
• Self-Contained Package: All dependencies properly bundled for offline installation

Python Environment Management (pythonEnvironment.ts)

• Retry Mechanism: Up to 2 retries with 2-second delays for transient failures
• Specific Error Messages: Context-aware error handling for README.md, pip install, and permission issues
• Progress Reporting: Real-time feedback during setup with descriptive progress messages

Extension Synchronization (extension.ts)

• Setup State Tracking: Proper setupState.isSetupComplete flag prevents premature ingestion attempts
• Timeout Protection: 5-minute maximum wait time prevents indefinite blocking
• Graceful Degradation: Setup failures don't crash the extension, allowing manual retry
• Progressive Setup Flow: Python environment setup integrated into main setup tasks
