From 50ee111714baa9d3bfe9bdba3b81e27cd1bdfe38 Mon Sep 17 00:00:00 2001 From: Ilya Brykau Date: Fri, 28 Aug 2026 17:26:26 +0200 Subject: [PATCH 01/63] fix(pipeline): suppress weak short-name matches for Go selector calls MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A Go selector call x.foo() whose receiver the Go LSP cannot type falls through to the generic registry resolver, which binds it by bare short name to an arbitrary same-named project symbol. Stdlib calls are the worst case: f.Close() on an *os.File gets a CALLS edge to whatever project Close wins candidate ranking (measured on a real Go repo: confidence 0.11, 15 candidates; suffix_match + unique_name were 36% of all CALLS edges, and one 14-line stdlib-only function got 3 out of 3 false outbound edges). Extend the TS/JS receiver-aware guard (#592/#606) to Go: - extract_calls.c: flag Go call_expression with a selector_expression callee as is_method, mirroring the TS/JS member_expression flag. - registry.c: add cbm_go_suppress_weak_method_match. Unlike the TS/JS drop-list, field_type_hint is KEPT (Go struct fields carry declared types, so the hint is receiver-aware — lrp_go_s8_field_type_hint), and unique_name is dropped only when its confidence carries the import-unreachability penalty (the stdlib-hijack shape); an unpenalized lone candidate inside the caller's import closure never enters the field-type-hint upgrade and must survive. - pass_calls.c / pass_parallel.c: feed the Go gate next to the TS/JS one; the drop still defers to the emit path so service/route/HTTP edges stay main-identical. Reproduce-first: pipeline_go_receiver_suppresses_weak_method_edge is RED without the extractor flag (the f.Close -> project Close edge exists) and GREEN with it; typed same-package calls, bare local calls and import-qualified cross-package calls still resolve. The old extraction contract test used Go as the flag-exempt language — Python takes that role, and extract_go_selector_call_flags_is_method pins the new behavior.

charset=UTF-8 Content-Transfer-Encoding: 8bit A Go method's QN was the flat package form (proj.pkg.method) — the receiver was ignored, so every same-name method in a package collided on one QN and the graph upsert kept exactly one node. Measured on a real Go repo: 20 Process/Name methods across 15 files kept 2 nodes; 9 different Task() methods fused into one chimera node carrying all nine bodies' call edges; 19 structs pointed DEFINES_METHOD at a single shared method node; a _test.go mock Close outranked the production Close in the dedupe tie-break. The upsert's own comment calls kind-disambiguated QNs 'the real cure'. Qualify the QN with the receiver type (proj.pkg.Recv.method), the same shape as Go interface members and the C++ out-of-line method path right below it in extract_func_def: - extract_defs.c: def.qualified_name = parent_class + name whenever the receiver type resolves; go_receiver_type_name becomes the shared cbm_go_receiver_type_name (exported via helpers.h) so both sides of the contract use one formula. - extract_unified.c (compute_func_qn): mirror branch for method_declaration, so method-body calls keep exact source attribution instead of degrading to File-node fallback (calls_find_source). - Consumers already agree: pxc_build_lsp_def passes the def QN and parent_class (receiver_type) verbatim into the Go LSP registries, and check_go_class_implements explicitly supports class-qualified method QNs (its path (b)). Side effect: resolve_same_module's exact module.name hash no longer matches concrete methods, which kills the conf-0.9 false edges where an interface-typed call bound to an unrelated same-package method.

The guard is wired into pass_parallel.c as well as pass_calls.c, but the four-file fixture only runs the sequential resolver, so the parallel hunk was bound by no test. The fixture is shared (write_go_receiver_fixture) and padded with 52 Go files past MIN_FILES_FOR_PARALLEL, with CBM_WORKERS=4, in the shape of the Python parallel twin. - registry.c: cbm_go_suppress_weak_method_match builds on the shared weak_short_name_strategy list and narrows it in two places only (field_type_hint kept, unique_name only when penalized). Behaviour is unchanged; weak_call_guards_share_one_drop_list now binds the Go guard to the shared list too. - test_extraction.c: the flag-exempt comment names the current flag set (Perl, Python, TS/JS/TSX and Go) and Rust as the exempt language.

HttpGet/HttpPost/.../ Route matched none of them, the class-prefix join ran only for Java and Kotlin, and ASP.NET templates are relative ("{symbol}", "api/[controller]"), while the path filter and ensure_one_decorator_route accept only '/'-prefixed paths. #1759 made every stacked C# attribute visible as DECORATES but did not turn any of them into a route. Fix: a C# path in push_method_def, next to the JVM prefix join, that reads the attributes of the action and of its class: - HttpGet/Post/Put/Delete/Patch/Head/Options with or without a template, [Route] on the class and on the action, [AcceptVerbs("GET", Route = "x")]; qualified names and the "Attribute" suffix are accepted. - [controller] is the class name minus "Controller", [action] the method name minus "Async" (the ASP.NET Core default) or its [ActionName], and [area] comes from [Area]. - A template is relative to the class prefix; "/" or "~/" overrides it. - Constraints, defaults and optional markers reduce to the bare parameter ("{id:int}", "{code:regex(^\d{{3}}$)}", "{page=1}" -> "{id}", "{code}", "{page}"), so the path is '/'-led and canonicalizes like every other decorator route. This works with both the current cbm_route_canon_path and the depth-matched variant. An action without a verb or [Route] attribute stays route-less, and other C# attributes never become routes. Known limits, unchanged in kind from the JVM path: one route per action (a stacked [HttpGet] + [HttpHead] records the first), and a [Route] inherited from a base controller in another file is not applied. Proof on jellyfin/jellyfin (shallow clone, depth 1, 208c278): Route nodes 0 -> 360, HANDLES 0 -> 388, e.g. GET /Items/{itemId}/Images/{imageType} <- ImageController.GetItemImage.

Every Go method QN changes (pkg.method -> pkg.Recv.method), so an index built before this change and refreshed incrementally would mix flat and receiver-qualified method nodes, with the old fused nodes keeping their stale edges. The bump routes such an index through one full rebuild. - pipeline_go_method_caller_keeps_lsp_join: the by-name assertion would also pass for a binding onto the decoy other.Decoy.helper. The test now pins the edge by QN suffix on both ends (.svc.Repo.Install -> .svc.Repo.helper) with an lsp_* strategy, and asserts no edge to the decoy. - extract_defs.c: the receiver-qualified def QN is Go-only. The templ grammar is Go-derived and reaches the same receiver branch, but its call-scope QN (compute_func_qn) stays flat, so a templ method would get a def QN no call names and its calls would degrade to the File node. extract_templ_method_qn_matches_call_scope pins def QN == call scope. - pass_semantic.c: the check_go_class_implements comment no longer describes Go method QNs as flat.

The extractor joined it to the imported name with another '.', recording "..x" for `from . import x`: the parent package. The import resolver then missed the real binding and fell to the symbol-name guess (the lexicographically first same-named definition in the project), so the import map, and the Python LSP binding that consumes it, sent every call to an unrelated function at import_map / lsp_callable_alias confidence. On home-assistant, 7,175 caller/callee pairs bound to another integration's function (webhook's `async_register` to accuweather's). Join without the extra separator when the module already ends in '.'. `from .m import f` (".m.f") and absolute imports are unchanged.

That helper capitalizes the receiver VARIABLE name and accepts any candidate whose QN contains it as a substring: `t.Run` on a *testing.T became `T` and bound a project `TBench.Run`. The sequential resolver has no such step. The Go selector guard treated field_type_hint as receiver-aware and kept it, so the same weak pick it drops in sequential mode survived in parallel mode under a new name. On caddy + prometheus, parallel and sequential CALLS diverged by 1,684 (this branch) and 5,560 (with receiver-qualified method QNs, which put type names into more QNs). At base the gap is 84. SCIP precision of Go field_type_hint is 0.016 at base. Go no longer takes the hint. The guard keeps field_type_hint on the shared weak list, and the fixture of both twins now pins the `t.Run` case. A typed field call (lrp_go_s8, `s.repo.Find()`) resolves through the Go LSP and is unaffected.

The Go doc-link model still let every method claim the flat node .: - doclink_go.c go_scan_method pushed a claim record; - doc_links_go.c go_add_claim put it in the flat table. So a type, function or value that shares its name with a method in its directory became a graph_gap ("lost its node to the method"), although the graph now gives it that node. Base reports the same graph_gap for this shape, because there the method really did take the node. So this completes #1913's QN scheme for one of its consumers; it is not a regression #1913 causes. - A method record now carries w `-`: it claims no flat name. - The resolver no longer enters methods into the flat table. Methods are found through their receiver (the member table), which was already the first lookup. - The flat fallback in go_method_node is now unreachable. It stays, with a comment saying so. Corpus, before = this branch's tree, par x2, r1 == r2: - terraform: graph_gap rows 9 -> 0, doc-link MENTIONS 528 -> 536 (+8, -0). All 8 new edges were judged correct: e.g. [AbsProviderConfig] now lands on the type, not on the method RootProviderConfig.AbsProviderConfig. - vault, prometheus: unchanged. - prometheus incremental == full for MENTIONS. - The 3 -> 4 index-format bump already forces a full rebuild, so no stored scope blob mixes the two meanings.

That is the fused-node defect #1913 removes. The expectations move to the new scheme, and each changed assertion pins an edge onto, or a count of, the receiver-qualified node (production: the previous commit and #1913): - sources: RefM's source is p.pkg.S.M, not p.pkg.M. - forms: [Widget.Run] lands on alpha.Widget.Run, [beta.Thing.Do] on beta.Thing.Do. - plain_text, struct_fields: Run's doc is the source alpha.Widget.Run. - lookup_order: two alpha.Run sources and beta.Promoted named no node any more, so they held vacuously. They are now alpha.Widget.Run and beta.Embedded.Promoted. The alias links land on beta.Thing.Do and alpha.Deep10.End. - node_owner, the positive contract that replaces the fused case: - two Method nodes, alpha.A.Close and alpha.B.Close, and none named alpha.Close; - [A.Close] and [B.Close] are edges, not graph_gap rows; - each method's own [Target] is an edge from its own doc line (9 and 12), with no unresolved row; - the type Open keeps alpha.Open: [Open] is the type (no graph_gap), [B.Open] is the method, and UsesOpen has 2 targets. - scope_blob: - method records carry w `-`; - swapping two methods of one name no longer changes the blob; - a func/type pair swap still does (new case); - the k1-k3 records follow (a method neither keeps nor contests a name); - a new k4 keeps the "two on one line contest it" rule covered with a var and a const. - incremental_equals_full: - [b.T.M], [b.W.Name] and [b.V.Name] all resolve, and U.M's [Target] is an edge; - removing T.M breaks only [b.T.M]; - swapping V.Name and W.Name moves nothing and is now an ordinary closure repair instead of a forced full rebuild. - scope_delta_rules: - a method/function swap is LOCAL; - removing the method of such a pair is LOCAL with the name "Open" (a member left); - new func/type cases keep the GLOBAL keeper-change rules covered for swap and removal. - workers_agree: [p01.T3.Close] now resolves (exact edge, no row). The graph_gap reason stays covered by the named Shared assertion: one function declared by every file of a package, which is still a gap.

The base resolvers ran the registry's name strategies instead, which prefer an import-reachable candidate, so the sibling lost as soon as the adapter's exc import resolved. cbm_registry_resolve_python_class_body_base looks the sibling up exactly (., both type-like) and requires it to be defined earlier in the same file, from the graph-buffer node lines: a later sibling is not bound yet when the base is evaluated.

It now follows the class's C3 order, the order super() uses, after the class's own members; a hierarchy without a C3 order keeps the depth-first walk. Each class is linearized once per file: the orders live in a per-file, arena-allocated open-addressing cache keyed by class QN, which also replaces the per-lookup cache of the super() resolver. The registry is complete before the walk starts, so an entry never goes stale; keys and the class entry of an order are arena copies. Linearizing a class costs one merge of its bases' cached orders, so no lookup re-linearizes a deep hierarchy.

Codex does the same and shows the server instructions as the namespace description of the deferred tools. Agents therefore reached for grep before the graph tools were even loaded (#509, discussion #2025). - tools/list: search_graph, trace_path and get_code_snippet carry _meta["anthropic/alwaysLoad"] = true (a documented per-tool hint), so the structural discovery path loads upfront while the other 14 tools stay deferred. About 4.6K characters of schema; clients that do not know the key ignore it, as MCP reserves _meta. - Server instructions (default profile) now state, keywords first and as facts, which structural questions the graph answers and where grep fits better: 309 -> 999 characters, within Claude Code's 4,096-character cut. - SessionStart/SubagentStart: the untrusted-metadata label now covers the graph-derived project name only. Wrapping the routing sentences too told the model to treat cbm's own guidance as data. The other sentences are unchanged; sanitization is unchanged. The initialize byte budget is raised deliberately from 512 B to 1.5 KiB (1,188 bytes now); tools/list stays within its 21 KiB budget (20,938 bytes).

The sequential build_import_map applies it in its fast and slow paths; the shared cbm_pxc_build_import_map (= _ex(..., false)) applies it in both loops, so no CALLS import map ever binds an annotation-only name. - The annotation consumers take cbm_pxc_build_import_map_ex(..., true): the cross-file base/field-type resolution and the Python LSP dispatch. The sequential dispatch always takes it; the parallel one builds that map only for a file that records a flagged import and otherwise passes its CALLS map, which is identical there by construction. - The Python LSP binds those names into an annotation-only frame consulted by annotation resolution after the ordinary scope chain: a runtime call through such a name never resolves. Tests: python_type_checking_imports_flagged_issue1277 (extraction), python_type_checking_typed_field_issue1277(_parallel) (pipeline, both venues; controls: no import_map and no LSP CALLS edge through the name).

The Python namespace facts already capture each module's top-level bindings in order; nothing consumed them, so those calls fell to name guesses that pick the first same-named definition under the package. - Records: cbm_pxc_collect_all_defs replays each module's COMPLETE fact stream into re-export, star-import and `__all__` records next to its defs, including for an import-only `__init__.py` (zero defs). Records carry the raw module spec; the Python registry resolves it (relative exactly, absolute by unique scope tail, else unknown). - Fold: the shared Python registry folds the records once, after finalize and before the seal, into a sorted per-module export table (binary search; no lookup in the registration loop). Order-deterministic; a cycle contributes what it has so far. - States (conservative): an incomplete fact stream publishes nothing; a shadow, delete or whole-namespace unknown (a top-level try/if/with) withdraws the names it covers; a star whose source cannot be enumerated publishes nothing; a literal `__all__` restricts a star, else public names only. - Consult: the Python LSP looks a module attribute up in the export table on a miss (calls, expression types, callable values) and when binding `from pkg import Y` where Y is no def of pkg. - Namespace facts read a module-level `if TYPE_CHECKING:` consequence as executed: lazy-module packages publish their names there.

With #1913 a Go method's QN carries its receiver, so the lookups found no node. The resolver is unchanged: for a Go method, rel(parent_class).name now equals the QN, so the method binds through its QN, like a member of any other language. - pdf_links_pipeline: page 1 names `server.Handler.Serve`; the edge target pkg.server.Serve becomes pkg.server.Handler.Serve. Same assertions: pdf_qn syntax, unique tier. - pdf_qn_method_through_owner, page 2: `time.Provider.Now` binds pkg.time.Provider.Now (was pkg.time.Now), syntax pdf_qn. - pdf_qn_method_through_owner, page 1: `time.Now` must not bind the method. The target moves to pkg.time.Provider.Now too. Against the old flat QN, no node exists any more, so the zero count would have passed vacuously. The page 2 assertion proves that the node exists. The ownerless-QN rule in doc_links_pdf.c stays: a templ method keeps the flat package QN while it carries parent_class (extract_defs.c only receiver-qualifies CBM_LANG_GO). Its comment no longer says that Go methods have no receiver.

The Go registrar splits that string on '|' (go_lsp.c split_pipe_types), so it got `(*Encoder, error)` as one piece. That piece did not parse, and a cross-file callee with more than one result, or with a named result `(e *Encoder)`, had no usable return type. As a result, `e, err := enc.NewEncoder()`, `h, _ := newHead()` and `_, d := diag.Run()` all left the variable untyped, and calls on it fell to name guesses. Same-file calls were fine, because they read the AST. Go defs now pass the parsed result list (extract_go_multi_return), '|'-joined: `*Encoder|error`, and `*Encoder` for the named result. Other languages keep the single raw string. The persisted LSP surface carries this string, so SURFACE_CODEC_VERSION goes from 2 to 3: existing caches re-extract Go surfaces once. The literal version-2 surfaces in the codec tests move to 3, so that they keep testing the envelope rule they name rather than the version mismatch.

Those are cleaned names for type-reference edges: clean_type_name strips `[]` and `*`. A cross-file single result `[]T` therefore reached the registrar as `T`. `xs := pkg.Generate(); xs[0].M()` lost its typing and fell back to a name guess. On prometheus the base binds `sample[0].T()` to chunks.Sample.T, but the first D1 change bound it to tsdb.T. pass_lsp_cross.c now leaves a single result's raw text alone, as before D1; the registrar already parses `*T` and `[]T`. Only a result LIST `(...)` is split, at its top-level commas, into raw element types: - `(*T, error)` -> `*T|error`; - the named `(t *T, err error)` -> `*T|error`; - the grouped `(a, b int)` -> `int|int`. `chan`, `func`, `map`, `struct` and `interface` never count as result names. A list that does not split cleanly keeps its raw text. Tests: the D1 fixture gains three call sites, each with two same-named decoys: - a single slice result indexed (`xs[0].TS()`); - a tuple with a slice element; - grouped named results.

A file with many trait-using classes paid O(classes x functions), and the scan grew with its own output. The class-field pass now keeps a receiver -> function-id index, synced incrementally as functions are registered, and flattening reads only the trait's own entries registered before the current class. If the index cannot be built, the previous full scan runs unchanged. Only entries registered before flattening started are visited, so the output is identical. Tests: the work-counter tests for #1265 (100 -> 200 trait-using classes, ratio gate 2.5) and #765 (trait collision shapes stay bounded) use the existing test-only work ceiling.

A barrier withdraws every name bound before it: sqlalchemy's sql/expression.py lost its 149 re-exports to the docstring after nullsfirst = nulls_first, and a docstring made an otherwise plain class unproven. A string literal now evaluates nothing in any quoting or prefix (r, b, u, rb), implicit concatenations included; an f-string with a replacement field stays an effect (__format__/__str__ may run code). from __future__ import x [as y] binds like a from-import of module __future__; a star import from __future__ is a syntax error and stays unsupported. CBM_PY_NAMESPACE_FACTS_VERSION moves to 2. The version travels in the lsp_surface py payload and a payload of another version does not decode, so the first incremental run on an index of an older binary falls back to a full re-index (delta.rehydrate_failed -> CBM_PIPELINE_FORCE_FULL_REINDEX) instead of mixing old and new facts. The codec test now spells the current version and rejects a version-1 payload.

The callee is a same-module function that never touches its parameter or the module's globals; only the submodules its body imports become package attributes. The extraction test pins the exact shape (the namespace survives, the imported submodules are shadowed at the call) and its controls: the body uses the parameter, global (also nested), globals(), sys.modules[__name__], the own package name, a same-module helper; an imported, rebound or not yet defined callee; an argument with an effect; a module-level locals.

The call is now allowed when the callee is the latest binding of its name, a proven same-module function with no star import or unknown effect since; every argument is a safe expression or a bare locals()/globals() the module does not rebind; and the body (nested scopes included) has no global/nonlocal and never names a parameter, a function or class the module defined earlier, the module's own name, or a name that reaches a namespace (globals, vars, locals, exec, eval, setattr, delattr, __import__, sys, importlib, __name__, __dict__, __globals__, __builtins__, builtins, __self__, inspect, f_globals, f_locals, f_back, gc). Each submodule of the package the body imports becomes a package attribute and is shadowed at the call; in a plain module the imports install nothing. Every other call stays a whole-namespace effect.

A test's request to the application, a production caller matched to a test's mock server, and the private mock servers of two tests pairing across files are not data flows of the application. #2689 links every caller of a route to every handler of it, so these pairs were made on main. try_create_data_flow now refuses a pair whose caller or handler is in a test file (cbm_is_test_file, the per-language rule extraction uses) when the two files differ. HTTP_CALLS and HANDLES are unchanged; only the pairing is scoped. The pass log counts the refused pairs (skipped_test_scope).
