* feat: same-arity overload disambiguation via type-hash suffix (#651)
Add ~type1,type2 suffix to Method/Constructor node IDs when same-arity
overloads with different parameter types exist in the same class. Also add
$const suffix for C++ const-qualified method overloads via new isConst field.
Key changes:
- typeTagForId() detects same-arity collisions and appends ~typeTag
- constTagForId() detects const/non-const collisions and appends $const
- TS/JS excluded from type-hashing (overload signatures collapse to impl body)
- Sequential findEnclosingFunction fixed: falls through on ambiguous same-class
candidates instead of picking first; fallback path includes typeTag + constTag
- Per-call-site integration tests across Java, C#, Kotlin, C++, TypeScript
- Cross-file + chain resolution tests for all 5 languages
- C++ isConst extraction via tree-sitter type_qualifier in function_declarator
1710 integration + 18 unit tests pass.
* fix: preserve generic/template args in type-hash, perf + type safety fixes
- Add rawType field to ParameterInfo preserving full type text (vector<int>)
while type stays simplified (vector). typeTagForId uses rawType for tags.
- Populate rawType in all 11 language method extractors
- Add buildCollisionGroups() to pre-group methods by name#arity (O(N) once
per class instead of O(N) per method call)
- Cache method extraction in call-processor findEnclosingFunction fallback
- Fix null guards on getLanguageFromFilename in all findEnclosing paths
- Tighten SKIP_TYPE_HASH_LANGUAGES to ReadonlySet<SupportedLanguages>
- Document ID stability invariant on first overload introduction
- C++ integration tests: template overloads (vector<int> vs vector<string>),
cross-file template + chain resolution, out-of-class method definitions
1718 integration + 20 unit tests pass.
* fix: add rawType to method-extraction unit test assertions
All 26 parameter .toEqual() assertions in method-extraction.test.ts
needed the new rawType field added to match ParameterInfo schema change.
* perf: cache tempMap/groups per class, consolidate extractFromNode
- Cache derived method map + collision groups per classNode.id in
parsing-processor (avoids rebuild per method in same class)
- Replace per-call extractFromNode with cached class extraction +
funcName:line lookup in call-processor fallback (avoids AST walk
per call site)
- Remove dead clearEnclosingFunctionCache export, fix JSDoc
* test: add sequential-path integration test for same-arity overloads
Add skipWorkers option to PipelineOptions to force sequential parsing.
New test suite verifies type-hash disambiguation produces identical
results through the sequential path (parsing-processor + call-processor
findEnclosingFunction) as the worker path.
