PCART-tools

An open-source program analysis toolchain for verifiable compatibility maintenance of Python and AI software under library evolution.

Modern Python and AI software systems heavily depend on rapidly evolving third-party libraries. PCART-tools provides tools, benchmarks, and evaluation artifacts for analyzing, repairing, and validating compatibility issues caused by API changes, dependency upgrades, and library evolution.

Start with PCART for API compatibility repair, PCREQ for compatible requirements inference, and PCBench / REQBench for benchmarks.

Toolchain at a Glance

Area Capability Repository
API compatibility Repair API parameter incompatibilities after library upgrades PCART
Dependency compatibility Infer compatible requirements for Python third-party library upgrades PCREQ
API ownership and provenance analysis Classify Python API call ownership and trace library usage provenance in Python projects PCResolve
Native API extraction Generate stubs for Python C extension APIs PCStubGen
Compatibility risks Detect variadic parameter compatibility pitfalls in Python APIs VPPDetector

Benchmarks and Artifacts

  • PCBench: Benchmark for Python API parameter compatibility issues.
  • REQBench: Benchmark for compatible requirements inference in Python third-party library upgrades.
  • PCART-evaluation and PCREQ-evaluation: Evaluation artifacts for reproducing experimental results.
  • PCART-LLM: Research artifact for LLM-based API compatibility analysis.
  • WebPCART: Web platform for PCART-based compatibility analysis.
