# Session Summary: VSCode Extension Improvements

**Date**: 2025-10-16
**Focus**: Search functionality, error handling, and testing infrastructure

## What We Built

### 1. Search UI in Sidebar ✅
- Added search icons to the Semantic Results panel title bar
- Search icon (magnifying glass) for text search
- Fuzzy search icon for semantic queries
- Welcome view with clickable search links when no results

**Files Modified**:
- `package.json` - Added view menu items, icons, and welcome view
- Icon updated to new SVG design

### 2. Better Error Handling ✅
Added intelligent error detection and actionable prompts:

**Query Execution Failures**:
- Detects "failed to execute sqry query" errors
- Shows dialog: "This might be due to an outdated or corrupted index"
- Offers "Rebuild Index" button

**Timeout Errors**:
- Detects timeout errors
- Offers "Increase Timeout" button → opens settings

**Binary Path Issues**:
- Detects missing sqry binary
- Offers "Open Settings" and "View README" buttons

**Files Modified**:
- `src/extension.ts` - Enhanced `handleError()` function (lines 344-408)

### 3. Query Parser Fallback Fix ✅
**Problem**: Text searches like "Error" were failing with validation errors

**Root Cause**:
- New AST parser successfully parsed "Error"
- Validator rejected it (expected `key:value` format)
- Error occurred after parse, so no fallback to old parser

**Solution**:
- Added validation error handling
- Falls back to old parser when validation fails
- Maintains backward compatibility

**Files Modified**:
- `sqry-core/src/query/executor.rs` (lines 561-570)
- `sqry-lsp/src/handlers/search.rs` (added debug logging)

### 4. Extension Packaging Fix ✅
**Problem**: Extension failed to activate due to missing `which` module

**Solution**:
- Removed `node_modules/` from `.vscodeignore`
- Now packages all production dependencies

**Files Modified**:
- `.vscodeignore` - Removed node_modules exclusion

### 5. Test Infrastructure ✅
Created comprehensive testing framework:

**Documentation**:
- `INTEGRATION_TESTS.md` - Full test plan with 9 test categories, 30+ test cases
- `tests/README.md` - Guide for running and writing tests
- `TESTING_SUMMARY.md` - Status, roadmap, and success criteria

**Test Files**:
- `tests/integration/search.test.ts` - Test skeleton with 6 test suites
- `tests/fixtures/test-workspace/sample.rs` - Rust test fixture
- `tests/fixtures/test-workspace/sample.ts` - TypeScript test fixture

**Test Categories Defined**:
1. Query Execution (text, structured, mixed, invalid)
2. Index Management (missing, outdated, rebuild)
3. Timeout Handling
4. Binary Path Validation
5. UI Integration
6. LSP Communication
7. Multi-Workspace Support
8. Error Recovery
9. Performance

## Key Learnings

### 1. Query Parser Architecture
The query execution flow:
```
User Input → New Parser → Validator → Optimizer → Executor
                ↓ (fail)      ↓ (fail)
            Old Parser ← ← ← ← ←
```

**Key Insight**: Validation failures weren't triggering fallback, only parse failures were.

### 2. VSCode Extension Packaging
- VSIX packages need `node_modules` for dependencies
- `.vscodeignore` controls what gets packaged
- Common pitfall: excluding too much

### 3. LSP Error Propagation
- Errors from Rust → LSP → Extension → User
- Each layer adds context but can obscure root cause
- Debug logging at each layer is essential

### 4. Error UX Best Practices
- Don't just show error message
- Offer actionable next steps
- Link directly to relevant settings/docs

## Testing Status

| Component | Status | Notes |
|-----------|--------|-------|
| Search UI | ✅ Built | Ready to test after VSCode reload |
| Error Handling | ✅ Built | Needs integration tests |
| Query Fallback | ✅ Fixed | Needs regression tests |
| Test Infrastructure | ✅ Created | Ready for implementation |
| Integration Tests | ⏳ Planned | Phase 1: 2-3 days |
| CI/CD | ⏳ Planned | After Phase 1 complete |

## Next Actions

### Immediate (Before End of Session)
1. ✅ Reload VSCode
2. ✅ Test simple search ("Error")
3. ✅ Test structured query ("kind:function")
4. ✅ Verify error dialogs work
5. ✅ Document any remaining issues

### Short Term (Next 1-2 Days)
1. Implement Phase 1 integration tests
2. Set up CI workflow
3. Add test fixtures for edge cases
4. Document known issues

### Medium Term (Next Week)
1. Complete all integration tests
2. Add unit tests
3. Achieve 80% coverage

2. View → Output
3. Select "Sqry" from dropdown
4. Look for `[DEBUG]` and `[ERROR]` lines

## Known Issues

### Resolved ✅
- ~~Text searches failing with validation error~~ → Fixed with fallback logic
- ~~Extension not activating (missing modules)~~ → Fixed .vscodeignore
- ~~Generic error messages~~ → Added specific handlers

- Performance with large repositories untested
- Multi-workspace scenarios untested
