Summary

  • Enhanced DataFrame query processor to support Python expressions in addition to existing filter operations
  • Added comprehensive validation and error handling for Python expression evaluation
  • Implemented security controls to prevent execution of dangerous operations
  • Added extensive test coverage for both filter and expression query types

Changes Made

  • mcp_tools/dataframe_service/tool.py: Updated to use new query processor interface
  • utils/dataframe_manager/query/processor.py: Enhanced query processor with Python expression support
  • utils/dataframe_manager/tests/test_query_processor.py: Added comprehensive test coverage

Test Plan

  • All existing filter-based query tests continue to pass
  • New Python expression query tests validate functionality
  • Security validation tests ensure safe expression evaluation
  • Error handling tests for malformed expressions
  • Integration tests with DataFrame service tool

Breaking Changes

None - maintains backward compatibility with existing filter-based queries.

- Updated DataFrameServiceTool to allow querying with both pandas query syntax and Python expressions.
- Modified the query method in DataFrameQueryProcessor to handle fallback from pandas query to Python eval, improving flexibility.
- Enhanced metadata tracking to indicate the method used for querying (pandas or Python).
- Added comprehensive tests to validate the new functionality and ensure correct behavior for various query scenarios.

This enhancement broadens the querying capabilities, making it easier for users to perform complex data manipulations.
