From ea2f6e0ecc508ff12d285f995e65319ea55333d3 Mon Sep 17 00:00:00 2001 From: Leo Meyerovich Date: Tue, 15 Jul 2025 02:05:32 -0700 Subject: [PATCH 01/55] feat(gfql): add GFQL validation framework MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add comprehensive validation framework for GFQL queries including syntax and schema validation. ## Python Code - `graphistry/compute/gfql/validate.py` - Core validation module with syntax and schema validators - `graphistry/compute/gfql/exceptions.py` - GFQLValidationError exception class - `graphistry/compute/chain_validate.py` - Chain function with validation support - `graphistry/validate/` - General validation utilities - Tests for all validation functionality ## Documentation - `docs/source/gfql/validation/` - Comprehensive validation guide - fundamentals.rst - Basic validation concepts and examples - advanced.rst - Complex query validation patterns - llm.rst - LLM integration patterns - production.rst - Production deployment patterns - API documentation for validation modules - Updated references in spec and main docs ## Notebook - `demos/gfql/gfql_validation_fundamentals.ipynb` - Interactive tutorial This provides a complete framework for validating GFQL queries at both syntax and schema levels, with helpful error messages to guide users. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- demos/gfql/gfql_validation_fundamentals.ipynb | 2285 +++++++++++++++++ docs/source/api/gfql/validate.rst

3c2222e13e53ff07d746bb05c0bc98d978db7379 Mon Sep 17 00:00:00 2001 From: Leo Meyerovich Date: Tue, 15 Jul 2025 21:57:34 -0700 Subject: [PATCH 02/55] feat(gfql): complete GFQL validation framework implementation - Added structured error system with E1xx-E3xx error codes - Updated all AST classes to use new validation pattern - Fixed ASTPredicate validate() method conflicts - Added schema validation to filter_by_dict - Created pre-execution validation capability - Updated all documentation and created migration guide Co-authored-by: Claude --- ai_code_notes/gfql/README.md | 20 +

Replace original gfql_validation_fundamentals.ipynb with updated content - Remove duplicate gfql_validation_fundamentals_updated.ipynb - Update notebook title to remove '(Updated)' suffix The original notebook was using the old external validation module, while the updated version demonstrates the new built-in validation system.

-This guide helps you migrate from the external validation system to the new built-in validation. - -## What Changed - -The GFQL validation system has been integrated directly into the AST classes, providing: -- Automatic validation during construction -- Structured error codes for programmatic handling -- Better performance with pre-execution validation -- More helpful error messages with suggestions - -## Migration Overview - -### Old System (External Validation) -```python -from graphistry.compute.gfql.validate import validate_syntax, validate_schema - -# Manual validation -issues = validate_syntax(query) -if issues: - for issue in issues: - print(f"{issue.level}: {issue.message}") -``` - -### New System (Built-in Validation) -```python -from graphistry.compute.chain import Chain -from graphistry.compute.exceptions import GFQLValidationError - -# Automatic validation -try: - chain = Chain(query) # Validates automatically -except GFQLValidationError as e: - print(f"[{e.code}] {e.message}") -``` - -## Key Differences - -### 1. Automatic vs Manual Validation - -**Before:** -```python -# Create query -query = [{"type": "n"}, {"type": "e_forward", "hops": -1}] - -# Manually validate -issues = validate_syntax(query) -if issues: - # Handle errors -``` - -**After:** -```python -# Validation happens automatically -try: - chain = Chain([n(), e_forward(hops=-1)]) -except GFQLTypeError as e: - print(f"Error: {e.message}") # "hops must be a positive integer" -``` - -### 2. Error Structure - -**Before:** -```python -class ValidationIssue: - level: str # 'error' or 'warning' - message: str - operation_index: Optional[int] - field: Optional[str] - suggestion: Optional[str] -``` - -**After:** -```python -class GFQLValidationError(Exception): - code: str # e.g., "E301" - message: str - context: dict # Contains field, value, suggestion, etc. -``` - -### 3. Error Types - -**Before:** Single `ValidationIssue` class with `level` field - -**After:** Specific exception types: -- `GFQLSyntaxError` (E1xx): Structural issues -- `GFQLTypeError` (E2xx): Type mismatches -- `GFQLSchemaError` (E3xx): Data-related issues - -### 4. Schema Validation - -**Before:** -```python -schema = extract_schema_from_dataframes(nodes_df, edges_df) -issues = validate_schema(query, schema) -``` - -**After:** -```python -# Runtime validation (automatic) -result = g.chain(query) # Raises GFQLSchemaError if invalid - -# Pre-execution validation (optional) -result = g.chain(query, validate_schema=True) -``` - -## Migration Steps - -### Step 1: Update Imports - -Replace old imports: -```python -# Remove these -from graphistry.compute.gfql.validate import ( - validate_syntax, - validate_schema, - validate_query, - ValidationIssue -) - -# Add these -from graphistry.compute.exceptions import ( - GFQLValidationError, - GFQLSyntaxError, - GFQLTypeError, - GFQLSchemaError, - ErrorCode -) -``` - -### Step 2: Remove Manual Validation Calls - -Old pattern: -```python -def process_query(query): - # Validate first - issues = validate_syntax(query) - if issues: - return None, issues - - # Then execute - chain = Chain(query) - return chain, None -``` - -New pattern: -```python -def process_query(query): - try: - chain = Chain(query) # Validation included - return chain - except GFQLValidationError as e: - # Handle error - raise -``` - -### Step 3: Update Error Handling - -Old pattern: -```python -issues = validate_query(query, nodes_df, edges_df) -for issue in issues: - if issue.level == 'error': - logger.error(f"{issue.message}") - else: - logger.warning(f"{issue.message}") -``` - -New pattern: -```python -try: - result = g.chain(query) -except GFQLSyntaxError as e: - logger.error(f"Syntax error [{e.code}]: {e.message}") -except GFQLSchemaError as e: - logger.error(f"Schema error [{e.code}]: {e.message}") - if e.code == ErrorCode.E301: - logger.info(f"Available columns: {e.context.get('suggestion')}") -``` - -### Step 4: Use Error Codes - -Error codes enable programmatic handling: - -```python -try: - result = g.chain(query) -except GFQLSchemaError as e: - if e.code == ErrorCode.E301: # Column not found - # Suggest available columns - print(e.context.get('suggestion')) - elif e.code == ErrorCode.E302: # Type mismatch - # Show type information - print(f"Column type: {e.context.get('column_type')}") -``` - -### Step 5: Leverage Collect-All Mode - -New feature for getting all errors at once: - -```python -# Get all validation errors -chain = Chain(query) -errors = chain.validate(collect_all=True) - -for error in errors: - print(f"[{error.code}] {error.message}") -``` - -## Common Patterns - -### Pattern 1: Query Builder with Validation - -```python -class QueryBuilder: - def __init__(self): - self.operations = [] - - def add_operation(self, op): - # Test validates immediately - test_chain = Chain(self.operations + [op]) - self.operations.append(op) - return self - - def build(self): - return Chain(self.operations) -``` - -### Pattern 2: Pre-execution Validation - -```python -def safe_execute(g, operations): - # Validate before expensive execution - chain = Chain(operations) - - # Pre-validate schema - if hasattr(chain, 'validate_schema'): - errors = chain.validate_schema(g, collect_all=True) - if errors: - logger.warning(f"Found {len(errors)} schema issues") - - # Execute - return g.chain(operations) -``` - -### Pattern 3: Error Recovery - -```python -def execute_with_fallback(g, operations): - try: - return g.chain(operations) - except GFQLSchemaError as e: - if e.code == ErrorCode.E301: - # Try without the problematic filter - field = e.context.get('field') - logger.warning(f"Removing filter on missing column: {field}") - # ... modify operations ... - return g.chain(modified_operations) - raise -``` - -## Backward Compatibility Notes - -1. **Empty chains remain valid** - No breaking change -2. **Old validation module still exists** - But deprecated -3. **Error handling is stricter** - Errors that were warnings may now raise - -## Benefits of Migration - -1. **Performance**: No separate validation pass needed -2. **Developer Experience**: Errors caught immediately during construction -3. **Better Messages**: Structured errors with suggestions -4. **Type Safety**: Specific exception types for different error categories -5. **Flexibility**: Choose between fail-fast and collect-all modes -
