From 39f41c3d4795dbe248219d4bf5b5b6da3a027960 Mon Sep 17 00:00:00 2001 From: Martin Vogel Date: Sat, 9 May 2026 14:16:15 +0200 Subject: [PATCH] =?UTF-8?q?feat(py=5Flsp):=20close=20all=20stress=20gaps?= =?UTF-8?q?=20=E2=80=94=20lambda,=20dict-dispatch,=20async,=20callable,=20?= =?UTF-8?q?next,=20kwargs?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Round 10. Closes the last documented gaps from Round 9 plus 21 new real-world stress tests covering SQLAlchemy / Pydantic / dataclass / TypedDict / Protocol / generator / async patterns. Lambda call-site inference: - PyLSPContext gains a per-context lambda registry. `fn = lambda x: body` records the lambda's AST node bound to fn. At call site fn(arg), we push a sub-scope, bind lambda params from arg types, and walk the body. Edges emitted under a synthetic child of the enclosing function so traces attribute correctly. Dict-literal dispatch table: - `funcs = {"a": foo, "b": bar}` records per-literal-key target QNs in CBMDictLiteralEntry[]. funcs["a"]() emits an edge directly to foo's QN with strategy=lsp_dict_dispatch. Async with / async for: - `async with X() as f` looks up __aenter__ before __enter__. __aenter__'s declared return type wins; the manager type is the fallback (async __aenter__s typically return self). - `async for x in iter` falls back to __anext__'s return type when the iterable's TEMPLATE form isn't recognized as AsyncIterator / AsyncGenerator. Callable / next / iter: - `f()` where f resolves to CBM_TYPE_CALLABLE returns the callable's return type. TEMPLATE("Callable", [..., R]) returns R. - factory()() / (lambda)() etc — when the function expression is itself a call / parenthesized / lambda, evaluate it and use its return type. - `next(it)` returns py_iterable_element_type(type-of-it). - `iter(x)` is identity. *args / **kwargs typed-parameter wrapping: - `def f(*args: T)` -> args is TEMPLATE("tuple", [T]). - `def f(**kwargs: T)` -> kwargs is TEMPLATE("dict", [str, T]). - Detected by walking typed_parameter > list_splat_pattern / dictionary_splat_pattern wrappers in py_bind_parameters. Tuple / list / set / dict literal expressions: - py_eval_expr_type now builds structured TUPLE / TEMPLATE types from element types of the literal. `(Foo(), Bar())` -> TUPLE([Foo, Bar]); `[Foo()]` -> TEMPLATE("list", [Foo]); `{"k": Foo()}` -> TEMPLATE("dict", [str, Foo]). Without this, unpacking lost element precision. Match sequence pattern: - list_pattern wraps each element in another case_pattern; capture appears as dotted_name -> identifier; splat as splat_pattern. Element-binder walks both wrappers and binds capture/splat to the subject's iterable element type / list[elem]. Stress test suite expanded from 22 to 43 patterns. All 43 hard- asserted as PASS: - typing helpers: NamedTuple, TypedDict (incl. total=False), Protocol (nominal + structural), ABC + abstractmethod, Mapped[T] (SQLAlchemy 2.0), Pydantic-style BaseModel - control flow: with-as via __enter__, except-as, post-early-return narrowing, async with via __aenter__, async for via __anext__ - containers: tuple unpack from function return + literal, dict.items() comprehension k/v unpack, list slice, dict.get default, recursive self-referencing types via forward refs - decorators: factory + functools.wraps, classmethod chained to method, property setter - inheritance: Self in chain, diamond MRO with C3, multi-class match - functional: lambda call-site inference, function-as-dict-value dispatch, callable return-value, next(iter), generator delegation (yield from), iterator next, double-star **kwargs, isinstance | branches, module-level const, dataclass + default_factory Bench: 178 LOC, 52 calls, **52 resolved (100%)**, 11.25 ms (ASan + UBSan). Total 2941 / 0. Zero remaining KNOWN GAPs in the stress suite — every probed pattern resolves. --- internal/cbm/lsp/py_lsp.c | 436 ++++++++++++++++++++++++++++++++++-- internal/cbm/lsp/py_lsp.h | 27 +++ tests/test_py_lsp_stress.c | 437 +++++++++++++++++++++++++++++++++++-- 3 files changed, 859 insertions(+), 41 deletions(-) diff --git a/internal/cbm/lsp/py_lsp.c b/internal/cbm/lsp/py_lsp.c index 3b520103b..474df5b29 100644 --- a/internal/cbm/lsp/py_lsp.c +++ b/internal/cbm/lsp/py_lsp.c @@ -33,6 +33,11 @@ static const CBMType* py_lookup_field(PyLSPContext* ctx, const char* type_qn, static void py_register_instance_field(PyLSPContext* ctx, const char* class_qn, const char* field_name, const CBMType* field_type); static void py_bind_for_target(PyLSPContext* ctx, TSNode left, const CBMType* elem_type); +static void py_register_lambda(PyLSPContext* ctx, const char* name, TSNode lambda_node); +static void py_register_dict_literal(PyLSPContext* ctx, const char* name, TSNode dict_node); +static TSNode py_lookup_lambda(PyLSPContext* ctx, const char* name); +static const char* py_lookup_dict_dispatch(PyLSPContext* ctx, const char* var, + const char* key); void py_lsp_init(PyLSPContext* ctx, CBMArena* arena, const char* source, int source_len, const CBMTypeRegistry* registry, const char* module_qn, CBMResolvedCallArray* out) { @@ -174,6 +179,117 @@ static char* py_node_text(PyLSPContext* ctx, TSNode node) { return out; } +/* ── lambda + dict-literal-dispatch registries ────────────────── */ + +static void py_register_lambda(PyLSPContext* ctx, const char* name, TSNode lambda_node) { + if (!ctx || !name) return; + if (ctx->lambda_count >= ctx->lambda_cap) { + int new_cap = ctx->lambda_cap == 0 ?
