From b618ba210d77582f2dfe1b8a2585f3e40cd979d3 Mon Sep 17 00:00:00 2001 From: Rahul Krishna Date: Wed, 26 Aug 2026 20:50:31 -0400 Subject: [PATCH 01/22] docs(design): spec the tsc + defuse linker call graph, Jelly removal (#98) --- docs/design/specs/defuse-linker-call-graph.md | 144 ++++++++++++++++++ 1 file changed, 144 insertions(+) create mode 100644 docs/design/specs/defuse-linker-call-graph.md diff --git a/docs/design/specs/defuse-linker-call-graph.md b/docs/design/specs/defuse-linker-call-graph.md new file mode 100644 index 0000000..6bf38c6 --- /dev/null +++ b/docs/design/specs/defuse-linker-call-graph.md @@ -0,0 +1,144 @@ +# tsc + defuse linker call graph (Jelly removal) + +- **Status:** accepted, not yet implemented +- **Scope:** `codeanalyzer-typescript` only; one PR, tracked in #98 +- **Tracking:** #98 (work item); branch `feat/issue-098-defuse-linker`, stacked on + `refactor/issue-096-native-v2-model` (#97) — lands after it merges +- **Parity precedent:** codeanalyzer-python 1.2.0, which replaced PyCG's global fixpoint with + Jedi + a per-callable defuse linker + (`codeanalyzer-python/docs/design/specs/2026-08-25-defuse-linker-call-graph-design.md`, #148 + there).

On the vscode-class targets we want to analyze, the Jelly leg is unusable; the tsc +leg alone loses exactly the edges Jelly recovers. + +Measured on the repo fixtures (union provider, L2): 79 edges total, of which **6 are +jelly-only**, in four sharp classes: + +| Class | Fixture evidence | +| --- | --- | +| Decorator invocations | `UserController.show → Get`, `→ Param`, `list → Get` (sample-app) | +| Library-mediated callback edges | `UserService.describeAll → ` (lambda passed to `.map`) | +| Receiver typing inside anons | ` → User.describe` (element type of the mapped array) | +| Param-flow calls | ` → named` via a function-valued parameter (anon-app) | + +Small counts, but the classes are the point: each is a bounded, per-callable resolution problem. +The expensive substrate already exists in this repo as the L3 kernels +(`src/dataflow/defuse.ts` — k-limited access-path def-use with the flow-insensitive alias +substrate — plus the CFG machinery). The replacement follows the same Joern/Fraunhofer CPG +architecture python adopted: a fast base graph from the type-checker, then a **local** linker +pass that backfills what the resolver missed. No global fixpoint anywhere. + +## Contract-impact triage + +| Question | Answer | +| --- | --- | +| Schema v2 shape (node/edge kinds, fields, ids, levels) | unchanged; schema_version stays **2.1.0** | +| `prov` vocabulary | `"jelly"` disappears; **`"defuse"`** coined for linker-derived edges (technique-named, matching python's `"defuse"` and the DDG's `"reaching-defs"`/`"points-to"`). `"tsc"` and `"import"` unchanged.

SDK `prov` is passthrough (`List[str]` — verified), no model change | +| CLI (**BREAKING**) | `--call-graph-provider` and `--tsc-only` removed; one code path, no backend flag (python: "the linker is cheap and deterministic; nothing to opt out of") | + +## Locked decisions (design session 2026-08-26) + +1. **tsc resolver is the base call graph, always.** Its edges keep `prov: ["tsc"]`; RTA + expansion and the phantom/import leg (`prov: ["import"]`) are untouched. +2. **Jelly is removed wholesale**: `src/semantic_analysis/jellyProvider.ts`, the union provider + and `selectProvider`, `options.callGraphProvider`, both CLI flags, the `__jelly` argv mode in + `src/main.ts`, `CANTS_SELF_JELLY`, the `@cs-au-dk/jelly` dependency, its `patches/`, and + `union-provider.test.ts` (superseded by the linker suite + reference validation). +3. **The linker runs at L2 with targeted kernels**: def-use state is built only for callables + that still contain unresolved call sites after the tsc leg. Per-callable, no fixpoint, + **sorted iteration mandated** — deterministic by construction. +4. **Linker edges carry `prov: ["defuse"]`** and merge with tsc edges through the existing + `mergeCallGraphs` provenance union. Resolutions reach the L1 `call` body nodes through the + same channel the tsc leg uses today, with python's cache rule preserved: linker resolutions + are **never persisted into `callee_signature`** (the symbol table round-trips the analysis + cache; a persisted resolution would resurface on a warm run with the wrong provenance). +5. **External-callback edges are kept** — a deliberate, documented **divergence from python**: + when a function value (anonymous or named) is passed as an argument to an external or + unresolved callee, the linker emits `enclosing-callable → function-value`, + `prov: ["defuse"]`, **edge-only** (no body call node — matching Jelly's observed behavior; + there is no real call site in first-party code). Rationale: JS/TS is callback-central, and + 2.1.0 materialized anonymous callables as tree nodes precisely so they can be addressed — + they must stay reachable by edge, not only by containment. The parity clause covers shared + vocabulary, not per-language recall. +6. **Decorator invocations become linker edges**, same edge-only rule: decorators are captured + in the model (`decorators[]` with `qualified_name`) but their factory calls are outside + `walkBody`'s reach, so no body node exists today and none is added (adding one would move the + wire). The linker resolves `qualified_name`/`name` against the symbol table and emits + `decorated-owner → decorator`, `prov: ["defuse"]`. +7. **No backend flag.** One code path. + +## Tier ladder + +Tiers land in order; the Joern ledger (below) decides how far down the ladder the +implementation must go before the gate is clean. Each tier is per-callable or bounded-round — +never a fixpoint. + +- **T1 — local value chase.** For an unresolved call site whose callee expression is a local + binding: chase the def-use chain (existing `defuse.ts` kernels, k-limited access paths) + through alias assignments (`const f = handler; f()`) to a function literal / declaration / + import binding. Imports resolve cross-module through the symbol table (the checker already + did most of this; the chase covers what it declared as "a variable", not "a function"). +- **T2 — decorator edges** (decision 6). +- **T3 — external-callback rule** (decision 5). +- **T4 — interprocedural votes, bounded.** A type-oracle round in python's style, narrowed by + what tsc already proves: (a) function values passed at **resolved internal** call sites vote + for the callee's parameter — a parameter-invoking site (`cb()`) resolves to the voted + functions; (b) return summaries (`return inner` / unique ctor returns) let + `const f = factory(); f()` resolve; (c) `this.x = fn` property assignments type + `this.x()` sites. Two bounded rounds (round one's resolutions vote before round two), + internal-target votes only. +- **T5 — CHA-by-name fallback.** Receiver call sites that survive every typed tier resolve to + every internal callable of that method name (bounded per site) — the over-approximation Joern + itself emits for untyped receivers. Applied last so precise resolutions are never widened. + +## Reference validation (the enforced gate) + +Mirrors python's method, per the maintainer's mandate: iterate edge-for-edge against **Joern +`jssrc2cpg`** (available in `~/workspace/codellm-devkit/joern-dist`) until our call graph is a +**strict superset of every real edge** Joern produces on the validation corpus: + +- **Corpus:** `test/fixtures/sample-app`, `dataflow-app`, `anon-app`, plus **one real-world + express/nest application** vendored or pinned at implementation time (the toy fixtures alone + are too small to trust a superset claim). +- **"Real edge"** = both endpoints exist in source and are nameable in this schema; Joern's + synthetic families (`N` internals where we hold the positional anon node, ``, + ``, fabricated members) are excluded through a **committed exception ledger, audited + per class** — python's discipline, not a waiver. +- **Scale benchmark:** microsoft/vscode at L1/L2 — wall-clock, peak RSS, edge counts by `prov` + — reported in the PR next to Joern `jssrc2cpg` on the same tree (or its failure mode). The + giant-JSON emission ceiling is out of scope here (separate issue); the benchmark measures the + analyze/compute phase and the Bolt projection path. + +## Acceptance + +- Joern superset ledger committed: 100% real-edge coverage per corpus app, every residual + classified. +- **Jelly-recovery spike metric** (python's PyCG analog): of today's jelly-only edges on the + fixtures, the % the linker recovers — reported in the PR, no hard gate (some jelly edges may + be judged junk by the ledger; the report says which and why). +- **A/B determinism:** paired runs byte-identical on the corpus `call_graph` (the linker adds + no nondeterminism; tsc inference is deterministic — stronger than python's Jedi caveat). +- Full suite, typecheck, monotonicity and Neo4j conformance gates green; `git grep -li jelly` + over `src`/`packaging`/`patches`/`package.json` returns nothing; the binary loses its + `__jelly` mode and shrinks. + +## Release plan + +- Ships in the analyzer's next MINOR (with the #96 native-model rewrite already queued for it); + release notes carry **BREAKING** lines for the removed `--call-graph-provider`/`--tsc-only` + flags — python 1.2.0 precedent for a flag removal in a minor. schema_version untouched. +- **python-sdk follow-up (tracked in this spec; file the issue when picked up):** remove the + `tsc_only` kwarg chain and its `--tsc-only` pass-through, then bump the SDK's pinned analyzer + version. Until it lands, `tsc_only=True` against the new binary is the one known break.

The ratified contract (python PR #160, spec PR #158) differs materially; this rebuilds the layer to it: - Artifact ids are LANGUAGE-NEUTRAL (can://artifact//): the first can:// segment is a namespace, so sibling analyzers over one repo emit the same id for the same file. - Artifacts are flat nodes: format, roles[] (union across rule matches), sha256, size_bytes, verbatim UNBOUNDED source (python's decision), extraction status. Capture is rules-matched only (shipped glob table + shebang scripts); text-cap flags removed. config_keys dropped — python's unit 4 owns config extraction. - Dependencies are FLAT evidence rows on the application (no node ids): kind runtime|dev|optional|build + the coined additive 'peer', declared_in (artifact id, re-stamped per run), provides_imports (@types/x also provides x, DT scope-mangling unmangled), prov declared/lockfile; JSON-lock family backfills locked_version on the sibling manifest's records. - unresolved_imports: every non-relative non-builtin specifier root; a VALUE import needs the runtime package, import type is satisfiable by @types alone; --resolve-installed (opt-in) probes node_modules metadata (prov installed-metadata). - Neo4j 2.2.0: NEUTRAL :Artifact/:Package (purl pkg:npm/..., scoped %40-encoded) — the sanctioned prefix-gate exception so siblings MERGE onto the same nodes — HAS_ARTIFACT / DECLARES_DEPENDENCY(_k=kind) / LOCKS (coarse fan from every lock artifact) + the analyzer's own TS_PROVIDES / TS_UNRESOLVED_IMPORT into minted module-level :TSExternal ghosts.
