From b618ba210d77582f2dfe1b8a2585f3e40cd979d3 Mon Sep 17 00:00:00 2001 From: Rahul Krishna Date: Wed, 26 Aug 2026 20:50:31 -0400 Subject: [PATCH 01/65] 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.

Switched to a containment check: any assignment whose left side contains the tracked symbol anywhere in its subtree now blocks widening, deliberately over-inclusive (a missed edge, never a wrong one). Shorthand destructuring needed an extra step - { key } binds through a separate per-shorthand symbol that plain getSymbol() never matches, resolved via the checker's own getShorthandAssignmentValueSymbol. Also accept non-interpolated template literals (`` `KEY` ``) alongside string literals in both tiers, matching the literal tier's own acceptance - the same expression no longer resolves at L2 but not L3/L4. --- src/dataflow/configUse.ts | 60 +++++++++++++++++------ test/config-use.test.ts | 14 ++++++ test/fixtures/artifacts-app/src/config.ts | 8 +++ 3 files changed, 68 insertions(+), 14 deletions(-) diff --git a/src/dataflow/configUse.ts b/src/dataflow/configUse.ts index 9b54e9f..08255d9 100644 --- a/src/dataflow/configUse.ts +++ b/src/dataflow/configUse.ts @@ -65,17 +65,29 @@ function resolveKeyThroughDataflow(read: TSConfigRead, project: Project, app: An if (!arg || !Node.isIdentifier(arg)) return null; const decl = arg.getSymbol()?.getDeclarations()?.[0]; if (!decl) return null; - // INTRA: `const/let/var key = "LITERAL"`, never reassigned. + // INTRA: `const/let/var key = "LITERAL"` (or a non-interpolated template literal), never reassigned. if (Node.isVariableDeclaration(decl)) { const init = decl.getInitializer(); - if (init && Node.isStringLiteral(init) && !isReassigned(decl)) return init.getLiteralValue(); - return null; + const value = literalTextOf(init); + return value !== undefined && !isReassigned(decl) ? value : null; } // INTERPROC (-a 4): a parameter whose every resolved caller passes one identical literal. if (level >= 4 && Node.isParameterDeclaration(decl)) return uniqueLiteralArgument(decl, app, project); return null; } +/** + * The value of a string literal OR a non-interpolated template literal, or undefined — mirrors + * the literal tier's own acceptance (`literalArgumentAt` in semantic_analysis/configUse.ts) so + * the same expression shape resolves the same way at every tier.

Example: `can://typescript/artifacts-app/src/config.ts/readHost@12:3`. +- **`Artifact.id` is language-neutral**: `can://artifact//` — no `typescript` segment, + so a TS and a Python analysis of one monorepo mint the *same* id for the same file (see the + `--app-name` trap below). +- **`Package.id` is a purl**: `pkg:npm/`, scoped `pkg:npm/%40scope/` — the + cross-language SBOM join key. +- **`ConfigKey.id`** is `@key/` (numeric segments for array indices, e.g. + `services.web.ports.0`). The `key` *property* is always the bare dotted name; the *id* alone can + carry an internal `arg.`/`env.` disambiguation prefix (see the `ARG` trap below) — never match on + a `key` substring expecting to see that prefix. + +## Standing traps + +**`direct` — dependency surface vs. supply chain.** + +> Your dependency *surface* and your dependency *supply chain* are different questions. +> "What does this app declare?" filters `direct: true`. "What actually ships / where does +> CVE-XXXX live?" needs the transitives — a vulnerable package four levels down is in your +> bundle whether or not you named it. + +Both recipes live side by side in `references/analyses.md` §6. Scoping note: every +`direct: false` record is a top-level lock entry carrying `kind: "runtime"` — a lock file does not +record *why* a package is present, so this layer asserts the safe default instead of inferring one. + +**`config_reads` shrinks as `-a` rises — deliberately.** It is the layer's one non-monotonic +section (`config_uses` is the opposite: asserted superset-monotonic, L2 ⊆ L3 ⊆ L4 — verified on +this branch's fixture at 21/25/29 uses and 10/9/8 reads across L2/L3/L4). A read unresolved at the +literal tier can close at a higher dataflow tier, so it *moves* from `config_reads` into +`config_uses` as the level climbs. Diffing two levels and seeing a `config_reads` record vanish +means "resolved at the higher tier," never "fixed in the code." Pair the two: `config_uses` is the +graph edge (`TS_USES_CONFIG`); `config_reads` never became an edge — it is JSON-only, a record of +absence, not a graph fact (analyses.md §7). + +**`--app-name` is the cross-analyzer join precondition.** Artifact ids are language-neutral +specifically so a TS and a Python analysis of one repository MERGE onto the same `:Artifact` node +— but only if both runs pinned the *same* `--app-name`. Two analyzers pointed at different +subdirectories of one monorepo, or run with mismatched app names, will silently disagree on every +artifact and package id and never merge. + +**`sha256` is always the full file; `source` may not be — and in Neo4j, `Artifact` has no +`source` at all.** Under `--artifact-text-max-bytes`, `text_truncated: true` in `analysis.json` +means the stored `source` is a prefix — hash-compare on `sha256`, never on `source`, and never +re-derive meaning from a truncated copy (the analyzer itself always parses the full on-disk text +for extraction). In the graph, this is moot for a different reason: `Artifact` carries `sha256` + +`size_bytes` but **no `source` property at all** — verbatim text lives only in `analysis.json`, by +design (`src/build/neo4j/project.ts`: "`source` text stays off the graph — hash and size +dereference to it"). A query like `WHERE f.source CONTAINS "..."` will not error; it will silently +match nothing. + +**`value` is present by default and absent under `--no-artifact-text`** — an absent `ConfigKey.value` +is a capture setting, not an empty or unset config key. Check `references/vocabulary.md`'s +`extraction` field before treating a missing `value` as "this key has no value." + +**Dockerfile `ARG` is not bindable.** `ENV` mints an `env`-namespace key that a `process.env` read +can join; `ARG` mints a `dockerfile`-namespace key that deliberately never joins one — it exists at +build time only. A query that unions the two namespaces (or filters `ConfigKey` without checking +`namespace`) will report build-time values as runtime configuration. This is also why the config-key +*id* sometimes carries an `arg.`/`env.` prefix (see Identity above): the same bare name can mint +twice on one artifact — a Dockerfile's `ARG VERSION` beside its own `ENV VERSION=$VERSION` — and +only the id, never the `key` property, disambiguates them. + +**`config_access` nodes are reads, not calls.** They carry `root`/`key?` (JSON only — not +projected to Neo4j) but no `callee` at any level, so joining them through `TS_RESOLVES_TO` finds +nothing — that relationship only ever targets a `call` node's resolution. Follow `TS_USES_CONFIG` +from the body node straight to the `ConfigKey` instead. + +**`TSExternal` ghosts come in two grains that do not share an id.** Call-graph targets +(`.../@external//`) and dependency/import-hygiene ghosts (`.../@external/`, +no name segment) sit on the same label but different ids — join them by the `module` property when +a query needs both (`references/vocabulary.md`, "External ghosts"). + +**No entrypoint or import-graph vocabulary exists yet.** `TSCallable` carries no `is_entrypoint`; a +"reachable from the entrypoints" query needs a root set you supply yourself (analyses.md §2). A +module's `imports[]`/`exports[]` (specifiers, aliases, type-only flags) live only in +`analysis.json`'s `TSModule` — `TS_UNRESOLVED_IMPORT`/`TS_PROVIDES` cover the dependency-hygiene +case only, not a general per-module import graph. + +Every trap above is a silent-empty-result failure, not an error: Cypher does not reject a query +naming a nonexistent label, property, or relationship — it just returns nothing.

On vscode one such mock (extensions/microsoft-authentication/packageMocks/ dpapi/dpapi.js, `throw new Error(...)`) aborted the entire 9,351-module run at -a 2, -a 3 and -a 4, writing no output; -a 1 was unaffected because it never resolves callees. Route the eight checker calls in the resolver, the defuse linker and the config-use dataflow tier through schema/checker.ts, which degrades a throw to undefined. Every caller already has an unresolved path — a call site whose callee will not resolve simply contributes no edge — so the cost is the edges at that one node instead of the whole analysis. On vscode that is 10 skipped resolutions against 1,149,980 call edges. The skips are counted and reported at the end of a run: "some edges are missing" must never be indistinguishable from "there were no edges". isReassigned() returns early when the binding will not resolve, so an undefined symbol cannot compare equal to another unresolved one and fake a reassignment match. --- src/core.ts | 6 ++ src/dataflow/configUse.ts | 12 ++-- src/schema/checker.ts | 51 +++++++++++++++++ src/schema/index.ts | 1 + src/schema/signatures.ts | 5 +- src/semantic_analysis/defuseLinker.ts | 16 +++--- test/checker-guard.test.ts | 57 +++++++++++++++++++ .../unresolvable-js-app/mocks/dpapi.js | 13 +++++ .../fixtures/unresolvable-js-app/package.json | 4 ++ .../fixtures/unresolvable-js-app/src/index.ts | 7 +++ .../unresolvable-js-app/tsconfig.json | 4 ++ 11 files changed, 163 insertions(+), 13 deletions(-) create mode 100644 src/schema/checker.ts create mode 100644 test/checker-guard.test.ts create mode 100644 test/fixtures/unresolvable-js-app/mocks/dpapi.js create mode 100644 test/fixtures/unresolvable-js-app/package.json create mode 100644 test/fixtures/unresolvable-js-app/src/index.ts create mode 100644 test/fixtures/unresolvable-js-app/tsconfig.json diff --git a/src/core.ts b/src/core.ts index 1f97141..48aec15 100644 --- a/src/core.ts +++ b/src/core.ts @@ -9,6 +9,7 @@ import type { AnalysisInternal } from "./schema"; import { type AnalysisResult, finalizeAnalysis } from "./schema/emit"; import { buildSymbolTable } from "./syntactic_analysis"; import { Logger } from "./utils"; +import { checkerFailures, resetCheckerFailures } from "./schema/checker"; export type { AnalysisResult } from "./schema/emit"; @@ -21,6 +22,7 @@ export type { AnalysisResult } from "./schema/emit"; export async function analyze(opts: AnalysisOptions): Promise { const log = new Logger(opts.verbosity); log.info(`analyzing ${opts.input} (level ${opts.analysisLevel})`); + resetCheckerFailures(); const cacheDir = opts.cacheDir ??

A TypeScript project's tsconfig normally leaves `allowJs` unset — false — so the file had no valid checker state, and resolving any identifier inside it threw inside tsc rather than returning undefined. That throw is what aborted vscode at -a 2/3/4; the guard in schema/checker.ts stops it being fatal, this stops it happening. Both Project construction sites (symbol table, dataflow worker) now go through createProject(), which merges `allowJs: true` over the tsconfig — verified to be the only option it changes, all 12 others survive. On vscode this removes every skipped resolution (10 -> 0) and trades 89 edges for 77. The 89 are not lost coverage: 74 carried prov `defuse`, the linker's CHA-by-name guess tier, which fired only because tsc could not type the receiver. One example, extensions/media-preview/media/imagePreview.js, is a standalone webview IIFE with no imports whose `e.preventDefault()` on a DOM event was matched by NAME to vs/base/browser/keyboardEvent.ts's StandardKeyboardEvent. Typed properly, the guess is never made. The 77 gained are tsc- and import-resolved. Cost: 6m25s -> 7m09s and 21.9GB -> 24.3GB on vscode, since JS is now checked. --- src/dataflow/worker.ts | 6 +-- src/syntactic_analysis/symbolTable.ts | 21 ++++++-- test/checker-guard.test.ts | 70 ++++++++++++++++++--------- 3 files changed, 66 insertions(+), 31 deletions(-) diff --git a/src/dataflow/worker.ts b/src/dataflow/worker.ts index 90d377a..20a80c8 100644 --- a/src/dataflow/worker.ts +++ b/src/dataflow/worker.ts @@ -13,7 +13,7 @@ */ import { Project } from "ts-morph"; import type { PdgEdge } from "../schema"; -import { defaultCompilerOptions, discoverSourceFiles } from "../syntactic_analysis"; +import { createProject, discoverSourceFiles } from "../syntactic_analysis"; import { extractCallableData, indexCallableDecls } from "./extract"; import type { CallableGraphData } from "./model"; import { sccFixpoint, type CallSiteRef, type FunctionSummary } from "./summaries"; @@ -49,9 +49,7 @@ function projectFor(root: string, tsConfigFilePath: string | null, skipTests: bo const key = `${root}|${tsConfigFilePath ??
