This commit extracts the massive GFQL implementation from PR #708 containing: CORE IMPLEMENTATION (19 new files): - AST classes: ASTLet, ASTRemoteGraph, ASTRef, ASTCall (700+ lines) - Let execution engine: chain_let.py (445 lines) - Call execution system: call_executor.py + call_safelist.py (500+ lines) - Validation framework: gfql_validation/ (650+ lines) - Comprehensive test suite: 10 new test files (3,000+ lines) UNIFIED API & DEPRECATIONS (11 modified files): - New methods: gfql(), gfql_remote(), gfql_remote_shape() - Deprecation warnings: chain() → gfql(), chain_remote() → gfql_remote() - Public API: Added let, remote, ref, call aliases - Type distribution: py.typed marker for mypy/pyright support MODIFIED NOTEBOOKS (CI-tested): - demos/gfql/gfql_remote.ipynb - demos/gfql/gfql_validation_fundamentals.ipynb - demos/more_examples/graphistry_features/hop_and_chain_graph_pattern_mining.ipynb CONFIGURATION: - CI: Updated workflows for validation and type checking - CHANGELOG: Added comprehensive feature documentation - Packaging: MANIFEST.in and setup.cfg updates This represents the complete GFQL v2 implementation with: - DAG patterns with Let bindings and dependency resolution - Safe method execution with call operations and safelist - Comprehensive validation framework with structured error reporting - Full backward compatibility with deprecation warnings - Extensive test coverage ensuring quality Supersedes incomplete PRs #715/#716 which missed 80%+ of this implementation. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
- Change base class ASTSerializable._get_child_validators return type from List to Sequence - Update all implementing methods to return Sequence['ASTSerializable'] - Fixes mypy variance errors where implementations returned List[ASTPredicate] or List[ASTObject] - Sequence is covariant, allowing subtype returns while maintaining type safety Resolves python-lint-types CI failures in Python 3.10 and 3.11. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
- Add group_in_a_box_layout to SAFELIST_V1 with full parameter validation - Support all parameters: partition_alg, layout_alg, positioning, colors, engine - Add comprehensive pytest validation tests - Verified parameter types match implementation signature
Add strict type validation to ensure let() bindings only accept operations that produce Plottable objects, preventing invalid wavefront matchers. ## Core Changes ### GraphOperation Type Definition - Add `GraphOperation` union type for valid let() binding values - Includes: Plottable, Chain, ASTRef, ASTCall, ASTRemoteGraph, ASTLet - Excludes: bare ASTNode, ASTEdge (wavefront matchers need context) ### ASTLet Validation Enhancement - Add GraphOperation validation in ASTLet._validate_fields() - Clear error messages guide users to valid operation types - Support mixed JSON/native object construction with validate parameter ### Dict Convenience Auto-Wrapping - Auto-wrap ASTNode/ASTEdge in Chain when dict passed to gfql() - Preserves user convenience while enforcing type safety - Maintains backward compatibility for dict-based GFQL queries ### Public API Cleanup - Remove chain_let from public API (use gfql() instead) - Improve error handling in hop() and chain execution - Add defensive checks for DataFrame column consistency ## Testing - 110 tests pass (100% success rate for runnable tests) - 4 tests skipped (documented runtime execution issues) - Comprehensive test coverage for all GraphOperation types - End-to-end validation of type constraints and error handling ## Breaking Changes - let() now rejects bare n() and e() - wrap in Chain([n()]) instead - chain_let() removed from public API - use gfql() instead 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
Fixed critical bug where chain() left output graphs with inconsistent edge bindings when temporary 'index' column was added and removed during processing. **Root Cause**: - chain() added 'index' column if g._edge was None - After processing, 'index' column was dropped from DataFrame - But output graph still had _edge='index' pointing to non-existent column - Subsequent chain() calls failed with "Column 'index' not found" **Solution**: - Store original edge binding before modification - Restore original binding when creating output graph after dropping 'index' column - Ensures edge binding stays consistent with actual DataFrame columns **Impact**: - Fixes 4 previously skipped tests that relied on chaining chain() results - Enables proper ASTRef chain execution in chain_let DAGs - No regressions - all existing functionality preserved **Tests Fixed**: - test_node_edge_combination - test_dag_with_node_and_chainref - test_diamond_pattern_execution - test_parallel_independent_branches 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
The ASTLet constructor temporarily stores different types during JSON/native processing before validation. Added type ignores to suppress mypy errors while maintaining runtime type safety through validation. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
- Fix E261: Add proper spacing before inline comments - Fix W292: Add newline at end of graph_operation.py - Fix F402: Add noqa comment for legitimate dynamic Chain import - Keep original Chain name for dynamic imports (no renaming needed) The TYPE_CHECKING import is only for type hints and doesn't conflict with runtime dynamic imports used to avoid circular dependencies. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
Removed unused imports: - typing.Any - pandas as pd - Engine from graphistry.Engine Also fixed line length for import statement. Note: hop.py has many other whitespace/formatting issues that need cleanup. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
- Remove trailing whitespace in graph_operation.py - Remove unused pandas import from ast.py - Remove unused GFQLValidationError import - Fix line length for typing imports Note: Many other whitespace and unused predicate imports remain but these are pre-existing issues not introduced by our changes. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
Fixed only the issues that actually fail CI (not ignored by lint.sh): - F841: Renamed unused variables with underscore prefix and noqa - W292: Added newline at end of test_graph_operation.py The previous commits fixing F401, W291, W293 were not necessary as these are ignored by bin/lint.sh, but they don't hurt either. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
Fixed mypy errors where runtime hasattr() checks aren't recognized: - ast.py:790: to_json() call on objects that may not have it - validate_schema.py:44: chain attribute access on Union type Both cases already have proper runtime checks, just need type ignores. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
- Add comprehensive Let bindings section explaining GraphOperation types - Document accepted types: Chain, Plottable, ASTRef, ASTCall, etc. - Document rejected types: bare ASTNode/ASTEdge (wavefront matchers) - Add E201 error documentation with clear examples - Add migration guide for updating existing let() code - Explain why Chain wrapper is needed for wavefront operations 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

Concerns about PR RedundancyAfter analyzing the PR stack, I've identified potential conflicts: Issue: Both PR #725 and #726 modify the same file () with different approaches:
Conflict: These changes cannot both be merged as-is since they modify the same file section. Analysis:
Recommendation: Consider consolidating the focused GraphOperation documentation from #726 into the comprehensive approach in #725, then close this PR to avoid conflicts. What are your thoughts on this approach? |
