feat(structural): add conservative Python call edges by nia-sg-bot · Pull Request #30 · WildestAI/DiffGraph-CLI

nia-sg-bot · 2026-08-17T03:40:15Z

Summary

emit deterministic calls relationships for unambiguous same-file Python calls
attach exact call-site plus parser/query/blob provenance to every emitted edge
leave attribute dispatch, imported calls, duplicate definitions, and parameter/local shadows unresolved rather than guessing
document the resolution boundary and add a golden call-topology fixture

Scope

This is the smallest independently valuable call-topology slice of the deterministic Python baseline. It does not complete parser/language coverage or the full parent issue.

Part of #22

Validation

python3 -m pytest — 114 passed
git diff --check
canonical CLI JSON smoke: emitted one resolved call edge with call_site evidence
cross-repo: the wildest-vscode-ext schema-v2 parser accepted the generated artifact after npm run compile-tests
schema compatibility: no schema change; calls, resolved, and call_site already exist in v2
website claim review: current public release-truth remains unchanged because this PR is unreleased

No configured repository lint or typecheck gate was found.

Summary by CodeRabbit

New Features
- Python structural analysis now reports unambiguous same-file function calls.
- Call relationships include precise call-site locations and snippets.
- Analysis avoids reporting ambiguous, shadowed, attribute-based, or unresolved calls.
- Structural evidence includes content hashes, while symbol and relationship evidence includes parser and source details.
Documentation
- Updated structural output documentation to describe Python call-edge behavior and evidence metadata.

Walkthrough

Python structural parsing now extracts bare identifier calls, tracks bindings, resolves supported same-file targets, and emits calls relationships with call-site and parser evidence. Tests validate five golden records and conservative exclusions.

Changes

Python call relationship extraction

Layer / File(s)	Summary
Call collection and binding tracking `diffgraph/structural.py`	The Python parser records calls, enclosing callers, source locations, snippets, and scope bindings during AST traversal.
Call resolution and relationship emission `diffgraph/structural.py`	Same-file functions and classes are resolved when targets are unambiguous and unshadowed. Resolved calls become `calls` relationships with occurrence IDs and provenance evidence.
Call relationship contract and validation `README.md`, `tests/fixtures/python_calls.json`, `tests/test_structural.py`	Documentation describes call-site and parser evidence. Tests validate five conservative call relationships against the golden fixture.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 23016

The change can incorrectly resolve calls involving nested lexical bindings, producing misleading call relationships in generated graphs, and its provenance does not clearly identify the new resolution behavior. The PR should not merge until these risks are fixed or explicitly accepted by the owner.

- Around line 637-645: Update QUERY_VERSION or _parser_provenance to include a
distinct revision for call-resolution behavior, ensuring artifacts with and
without emitted calls have different provenance; update the regression test to
assert the new revision.
- Around line 250-258: Update _resolve_call_target to search bindings and local
candidates through enclosing function and method scopes, allowing nested
functions and methods to resolve their nearest lexical local shadow before
module-level symbols. Exclude class namespaces from this traversal, and add
golden cases covering closure bindings and method-local shadows.
