Plus `enhance_project` now populates the full model layer even on already-finalized projects. + +### 🚀 New Features + +- **LadybugDB Graph Engine Migration**: All graph query tools (`find_callers`, `find_callees`, `get_neighbors`, `get_subgraph`, `graph_query`, `shortest_path`, `get_graph_stats`, `get_entry_points`, `find_definition`, `find_references`) now go through LadybugDB Cypher exclusively. SQLite `graph_nodes`/`graph_edges` fallback removed. Results served from KuzuDB property graph (`(:Entity)-[:RELATES]->(:Entity)`). +- **`buildLadybugFromEntityRelation`**: New function that builds LadybugDB directly from `entity`/`relation` tables via CSV + Kuzu COPY FROM. Replaces the old `compileGraphToLadybugDB` which read from `graph_nodes`/`graph_edges`. 579ms for 1,387 nodes + 2,885 relations on CodeScope self-index. Legacy fallback preserved for unit tests. +- **`enhance_project` model build on finalized projects**: Fixed `engine_enhance_project` to run `runModelIndexSync` + `buildKnowledgeGraphSync` even when the project is already finalized. Previously returned early with `already_finalized` status, leaving `module_summary`, `modules`, `architecture_edge`, and `module_edge` tables empty.

Fixed by adding a `run_model_build` goto label that runs `runModelIndexSync` + `buildKnowledgeGraphSync` even on finalized projects. +- **`find_callers`/`find_callees` empty on re-indexed projects**: LadybugDB was not populated because `buildGraph` skipped LadybugDB init when `CODESCOPE_SKIP_ASYNC=1`. Fixed by `buildLadybugFromEntityRelation` being called from `buildGraph` unconditionally (when LadybugDB is initialized). +- **`compileGraphToLadybugDB` error message stale**: Error message in `store_graph.cpp` still referenced `compileGraphToLadybugDB` after migration to `buildLadybugFromEntityRelation`. + +### 🔧 Improvements + +- **`buildLadybugFromEntityRelation` performance**: 579ms for 1,387 nodes + 2,885 relations on CodeScope self-index.

Plus `enhance_project` now populates the full model layer even on already-finalized projects. -### What broke (the bugs we hit) +### What changed -| # | Bug | Symptom | Class | -|---|-----|---------|-------| -| 1 | `resolve_strategy` not propagated to `graph_edges` | `find_callees` / `find_callers` / `engine_get_callees` / `engine_get_callers` always returned empty `resolve_strategy`; third-party symbols (`dropout`, `backward_hook`, `means`, `stds`, `LSTMLayer`) surfaced as in-project callees — frontends could not filter them | Data-flow break | -| 2 | `buildCallEdgesSQL` dead code | `buildGraph()` casts `build_calls` to `(void)` (`store_graph.cpp:320`), so `buildCallEdgesSQL` was never called — but edits to it (including a `resolve_strategy` write attempt) silently had no effect. Root cause of Bug 1's missed fix path | Dead code / maintenance hazard | -| 3 | `get_module_tree` invalid JSON | `GraphStore::getModuleTreeJson` used one shared `first` flag across the whole recursion; after the first root, every children array started with a leading comma `[{,...},{...}]` — `json.loads` crashed on the client | Serialisation correctness | -| 4 | `verify_claim(capability_exists)` always Contradicted | `capability_verifier.cpp` LIKE direction reversed: `LOWER(?)

Verified on `bun` (8 languages): 100% of `edge_type=1` (call) edges carry a non-empty strategy. Frontends can now filter `external` / `unresolved` out of callee/caller results. -- **Bug 2 closed** by fully removing `buildCallEdgesSQL` (`store_intern.cpp` 704 → 17 lines) + the stale docstring in `store.h`. A comment block now points to the Resolver Pipeline and the bug doc for rationale, so future maintainers don't edit dead code. -- **Bug 3 closed** by threading `first` as a `bool &` parameter through `outMod` so each sibling list owns its own flag. Language-agnostic — any project with ≥2 module-tree levels reproduced and is now fixed. -- **Bug 4 closed** by flipping both LIKE clauses in `capability_verifier.cpp` (`capabilityDeclared` + `entitiesWithCallers`) to `LOWER(name) LIKE LOWER(?)||'%'`, aligning with the correct `name LIKE pattern` direction already used by `architecture_verifier.cpp` and `contract_verifier.cpp`. -- **Bug 5 closed** by adding `populateModulesHierarchy` (`async_knowledge.cpp`) called after `buildKnowledgeGraphSync` COMMIT — collapses `entity.module_path` directories into one `modules` row per distinct path, with `parent_id` resolved by next-shorter prefix, `file_count` and majority `language` per directory. Idempotent via `insertModule`'s existence check. Verified on `bun`: 253 modules rows, 21 roots, nested tree JSON valid. +- No breaking API changes. All MCP tools maintain the same JSON response schema. +- `enhance_project` now runs model building even on finalized projects — expect ~2s additional time on first call after upgrade. +- LadybugDB is now required (was optional). Install via `brew install ladybugdb` (macOS) or `curl -fsSL https://install.ladybugdb.com | sh` (Linux). +- `graph_nodes`/`graph_edges` tables are still written but no longer queried. Will be removed in v0.3. -### Also shipped +### Performance -- `test_bun.cpp` parameterised (`argv[1]` restored, hardcoded path retained as default). -- containment edges (edge_type=3) now write `resolve_strategy` via JOIN `semantic_records psr` — keeps the column populated for schema consistency (the strategy value itself is correctly empty for declarations). -- Bilingual bug-fix records in `docs/bugs/bug_resolve_strategy.{zh,en}.md`. -- FFI static-detection development plan in `docs/dev_plans/ffi_detection_plan.md` (next-next step, not shipped in 0.2.1). +| Metric | Value | +|--------|-------| +| LadybugDB build (CodeScope, 1,387 nodes) | 579ms | +| LadybugDB file size | 3.4MB (4.4% of SQLite) | +| Query latency (all graph tools) | ~1ms | +| `enhance_project` total | 2,655ms | +| `make check` | 85 Rust tests + 17 C++ LadybugDB tests — all pass | -### Open-source release preparation — documentation accuracy, build portability fixes, and new developer tooling +### Full changelog -#### New Features - -- **FFI Boundary Detection** (`codescope_ffi_boundaries`): Automatically detects cross-language FFI boundaries in the codebase — identifies `extern "C"` blocks, `#[no_mangle]` symbols, JNI declarations, and C ABI function exports. Helps developers audit unsafe interop surface. -- **Paginated Graph Export** (`codescope_export_graph`): Full graph export with cursor-based pagination. Supports configurable page size, filter by edge type, and streaming output for large codebases. Integrates with MCP tooling for seamless client-side consumption. -- **One-Click Bootstrap** (`codescope_bootstrap`): Zero-configuration project setup — auto-detects project language, runs indexing, and verifies the graph is ready. Single command from clone to queryable graph. -- **LadybugDB Embedded Storage**: Optional LadybugDB backend for graph storage — provides faster local graph queries vs SQLite, with automatic fallback. -- **LadybugDB incremental sync**: Added `lbug_sync_state` table to track incremental sync progress (last synced node id, edge rowid, and full-sync flag) so re-syncs only process new graph data. -- **ISSUE_TEMPLATE and CONTRIBUTING guidelines**: Added GitHub issue templates and `CONTRIBUTING.md` to guide open-source contributors. - -### Improvements - -- **Query Limits & Error Handling**: Added configurable query timeouts and result caps. Graceful error recovery for malformed queries — returns partial results instead of failing. -- **Graph Building Logic**: Optimized buildGraph to handle orphaned nodes and broken references without crashing. Better error messages for cycle detection and constraint violations. -- **MemberExpr False Positives Eliminated**: Fixed a bug where C++ `MemberExpr` (e.g., `obj.method()`) was incorrectly resolved as a direct call edge to unrelated functions. Now correctly distinguishes qualified member access from free function calls, improving call graph accuracy by ~15% on C++ codebases. - -### Bug Fixes - -- **macOS install instructions missing LadybugDB**: `README.md`, `QUICK_START.md`, and `bootstrap.sh` did not list LadybugDB as a dependency, but `server/build.rs` unconditionally links `liblbug`. Added `brew install ladybug` (macOS) and `curl -fsSL https://install.ladybugdb.com | sh` (Linux) to all install paths. -- **build.rs Linux library path portability**: The LadybugDB link search path was hardcoded to `/opt/homebrew/lib` (macOS-only). Now resolves the correct path per platform. -- **C++ FFI exception safety**: All `extern "C"` boundary functions are now wrapped in `try/catch` so a C++ exception never crosses the FFI boundary into Rust (which would abort the process). -- **CI now runs C++ tests**: GitHub Actions workflow updated to compile and execute the C++ test suite on every push. -- **Documentation consistency**: Corrected tool count (37, not 19 or 32), replaced stale 11-table list with the actual 40-table schema, expanded environment variables table from 3 to 11 entries, removed `graph_query` from the "does not exist" list (it is implemented), standardized token savings to 98.9%, and removed the stale `codebase-memory-mcp` benchmark table. -- **MemberExpr call edges**: C++ `a->foo()` and `b.foo()` no longer generate false positive edges to every function named `foo` in the project. Resolution now checks the qualifier type before matching. -- **Query timeout**: Long-running fuzzy searches no longer block the server. Configurable `max_query_time_ms` (default 5000ms). -- **Graph export OOM**: Paginated export prevents memory exhaustion on large graphs (100k+ nodes) by streaming results in pages of configurable size. - -### Code Review Fixes - -- **LadybugDB stale data on re-index**: `buildGraph` now calls `resetLadybugSyncState` before sync to force a full sync when the SQLite graph was rebuilt, preventing stale nodes/edges from accumulating in LadybugDB. -- **build.rs / CMakeLists.txt LadybugDB synchronization**: `build.rs` now reads the CMake cache (`CMakeCache.txt`) to determine whether CMake found `liblbug`, ensuring the Rust link step stays in sync with the `HAS_LADYBUG` compile definition. Eliminates the mismatch risk when LadybugDB is installed under a custom prefix. -- **CSV temp file collision risk**: Incremental sync CSV filenames now include `project_id` to prevent concurrent-project collisions. -- **CSV cleanup consistency**: Node and edge CSV error handling now uniformly retain the CSV for debugging on COPY FROM failure. -- **FFI contract clarity**: Added exemption comment to `engine_free_string` documenting why `free()` is exempt from the try/catch wrapper requirement. -- **Redundant try/catch removed**: Simplified `engine_find_connected_components` by merging the redundant inner/outer try/catch into a single wrapper. -- **ffi::init() return value checked**: `tools/mod.rs` now verifies the engine re-init return code after worker subprocess, preventing silent permanent failure. -- **Rust server panic safety**: Replaced 4 `serde_json::to_value().expect()` calls in `server.rs` with proper `-32603` error responses — server no longer crashes on serialization failure. -- **Removed dead `tokio` dependency**: The server is fully synchronous; `tokio` was unused and added compile time/binary size. -- **`engine_version()` FFI**: Added version function + `--version` CLI flag for runtime version inspection. -- **`.clang-format` rewrite**: Replaced 807-line Linux kernel config with 94-line project-specific config (`c++17`, removed GPL header, removed 600 irrelevant `ForEachMacros`). -- **C-style casts eliminated**: 12 `(const char *)` casts replaced with `reinterpret_cast` across `engine_ffi.cpp` and `query_analysis.cpp`. -- **Configurable `synchronous` mode**: `PRAGMA synchronous` now defaults to OFF but can be overridden via `CODESCOPE_SYNCHRONOUS=NORMAL|FULL|OFF` env var. -- **Chinese comments translated**: All CJK comments in `engine/src/` and `engine/include/` translated to English. -- **Global singleton thread-safety documented**: Added prominent contract block in `engine_internal.h` documenting the sequential-dispatch model and future migration path. - -### Chores - -- **Removed accidentally committed binary `version` file**: A stray binary artifact was removed from the repository. -- **Committed Cargo.lock**: Required for reproducible builds of the binary crate. Was previously gitignored. -- **Gitignored runtime artifacts**: `runtimelog/`, `llvm_ir/output/`, and `*.lbug` files are now properly ignored. -- **Open-source community files**: Added `CONTRIBUTING.md`, `SECURITY.md`, `CODE_OF_CONDUCT.md`, `.github/CODEOWNERS`. -- **GitHub Actions SHA-pinned**: All workflow actions pinned to commit SHAs for supply-chain security. -- **Non-destructive release pipeline**: `build.yml` no longer force-pushes tags or deletes existing releases. Added semver monotonicity validation. -- **CI timeout reduced**: 120min → 45min to fail fast on hangs. -- **Test suite expanded**: `TEST_EXES` expanded from 28 to 37 (added `test_fp_*`, `test_graph_semantic`, `test_semantic_unit`, `test_type_extraction`, etc.). Manual debug tools moved to `engine/manual/`. -- **Known-failing tests documented**: `test_enhance_e2e`, `test_fp_rust`, `test_fp_java`, `test_{js,ts,tsx}_visitor` excluded from `TEST_EXES` with documented reasons. +See [CHANGELOG.md](./CHANGELOG.md) for the complete list of changes, bug fixes, and code review findings. diff --git a/builtin-scheduler-design.md b/builtin-scheduler-design.md deleted file mode 100644 index 388571c..0000000 --- a/builtin-scheduler-design.md +++ /dev/null @@ -1,236 +0,0 @@ -# Built-in Scheduler Design — 内眮调床层讟计 -

Design Principles - -- **Reuse the existing IR pipeline.** Every new check emits a `Finding` via the - `verify/` registry (`VerifierRegistry`); no new top-level subsystem. -- **Visitor-side capture only what the AST already exposes.** No type-inference - engine, no control-flow solver. If the tree-sitter AST lacks the info, defer the - check — do not synthesize it. -- **Block-level FFI transfer** per `plan/rules/code_rules.md` §FFI: findings are - accumulated in C++ and returned as one JSON array, never one FFI call per finding. -- **File size ≀ 1000 lines.** Each verifier lives in its own `.cpp`; split when - a single verifier crosses 800 lines. -- **English comments, no silent errors, error chain `[module=, method=]`.** - -## 3. Phase 1 — MVP (2 verifiers, ~200 LOC) - -Goal: from "we found an FFI symbol" to "we found an FFI **bug**". - -### 1.1 Symbol declared/exported mismatch verifier - -`engine/src/verify/ffi_resolver_verifier.cpp` — registered into `VerifierRegistry`. - -For every `ffi_symbol` already detected by `engine_detect_ffi_boundaries` -(`extern_*`, `ffi_*`, `wasm_*`, `cabi_*`, `jni_*`, `CALLBACK_*`): - -1. Query `entity` for a matching definition (same `name`, `node_type=1` decl). -2. If no definition row exists → emit `Finding{rule="ffi_undefined_decl", severity=warn}`. -3. If the definition lives in a different language than the declaration's file → - emit `Finding{rule="ffi_lang_mismatch"}`. - -Reuses: `resolve_strategy=unresolved` (already set when the Resolver Pipeline cannot -find a definition), the `ffi_symbols` SQL already in `engine_detect_ffi_boundaries`. - -### 1.2 Project-id misselection guard (orthogonal but cheap) - -Add a `rootPath`-keyed lookup to `get_latest_project_id` callers so MCP -`initialize` reuses the project whose `root_path` matches `rootPath`, not `MAX(id)`. -(~30 LOC, in `engine_ffi.cpp` or `engine_internal.h`.) This is the issue you raised -today; fold it into Phase 1 because it blocks every MCP test. - -> **Update 2026-07-17**: verified in `engine/src/store/store_core.cpp:683-695` — -> `GraphStore::getLatestProjectId` already picks the project with the most -> `graph_nodes` (ties broken by `id DESC`), not `MAX(id)`. The empty-shell hazard -> is already mitigated. §1.2 is therefore **down-scoped**: keep a defensive -> `rootPath` match in MCP `initialize` as belt-and-suspenders, but not a blocker. - -## 3.1 Accuracy re-estimate — scope narrowed to in-project source - -Original §3-§5 estimates (60-92%) assumed the callee might be a third-party / stdlib -symbol whose ABI is not visible. **If we exclude third-party and stdlib callees -and only analyse FFI where both ends are defined in the target project source**, -the problem degrades from "cross-language semantic alignment" to "same-project -two-language signature alignment" — a qualitative change, because the callee -definition is in hand, no semantic guessing needed. - -| Phase | Detection | In-project accuracy | Reason | -|-------|-----------|---------------------|--------| -| 1 | undeclared extern, lang mismatch, missing export | **95-98%** | Discrete lookup in `entity` table; ~0 false positive | -| 2 | type mismatch, arity mismatch, panic-cross | **80-90%** | callee true signature pulled from project source, not a hand-maintained type-map; `void*` polymorphism is the residual ~10-20% miss | -| 3 | ownership transfer, UAF across boundary | **60-75%** | call-graph still has no time order; cross-function UAF needs control-flow, static topology only | - -### Three accuracy gains driving Phase 2 from 60-75% → 80-90% - -1. **callee true signature replaces the type-map table.** Phase 2's original - ceiling was the hand-maintained `c↔rust↔js↔python` type table — `char*` being - "out string" vs "in buffer" is statically undecidable. With the callee in-project, - both ends' signatures are in the AST: C `extern int process(const char* in, size_t len)` - ↔ Rust `pub extern "C" fn process(buf: *const c_char, len: usize) -> i32` — - align by parameter position, no `char*` semantic guessing. -2. **Arity mismatch goes from "shaky" to "deterministic".** Third-party arity - needs ABI docs (often wrong); in-project arity is "count the signature parameters". - C decl `extern void f(int, int, int)` ↔ Rust impl `fn f(a: i32)` — arity 3 vs 1, - discrete verdict, zero false positive. This class moves from "shaky detection" - to "confirmed bug". -3. **panic-cross from "high-risk pattern" to "locatable".** Third-party panic - paths are invisible (binary); in-project Rust callee panic paths are in source — - scan the callee body for `unwrap`/`expect`/`panic!`/`unreachable!`, emit finding. - False-positive rate drops from "uncertain" to "only misses, no false alarms": - misses happen when callee calls a third-party that panics (not scanned). - -### Hard constraints keeping accuracy ≀ 92% - -- **Cross-language ownership order**: C `free(x)` in function A, Rust `use x` in - function B — A→B or B→A needs control-flow. Static call-graph has topology only. - Cross-function UAF still misses ~15-20% in Phase 3. -- **Implicit conversion layers**: Rust `CString::into_raw` → C holds `char*` → - forgets to call `CString::from_raw`. This is a semantic bug, not a signature bug; - static AST cannot see it without lifetime annotation — out of scope. - -### How the project distinguishes custom code from third-party / stdlib - -Already solved today, reused verbatim by the FFI verifier: - -1. Each language Visitor's `resolveSymbol(name)` looks up the name in the current - file's scope stack. Hit → `resolve_strategy = "p1_intra"` (in-project, resolved). -2. Miss → `BuiltinRegistry::resolve(language, name)` (`engine/src/ir/builtin_registry.cpp:1765`) - consults a per-language registry of compiler builtins + stdlib symbols. Hit → - `"external"`. Miss → `"unresolved"`. -3. Each Visitor additionally has a language-local builtin filter - (`isCBuiltin` / `isPythonBuiltin` / `isRustBuiltin` / `isJsBuiltin` ...) that - **skips reference creation entirely** for compiler intrinsics (`__builtin_*`, - Python `len/print/str`, Rust `vec!/println!/dbg!`), so they never reach the - Resolver Pipeline and never pollute edges. -4. Public API: `BuiltinRegistry::isKnownExternal(name)` and - `externalSymbols(language)` give the verifier an O(1) third-party check. - -**FFI verifier decision rule** (cheap, discrete, no semantic guessing): - -``` -is_in_project := (resolve_strategy == "p1_intra") AND callee row exists in entity -is_third_party := BuiltinRegistry::isKnownExternal(callee_name) OR resolve_strategy == "external" -is_stdlib := callee_name in BuiltinRegistry::externalSymbols(language) -is_unknown := resolve_strategy == "unresolved" -``` - -The verifier **only analyses edges where `is_in_project` is true on BOTH ends**. -This is the scope narrowing that lifts accuracy to the 80-98% band above. -Third-party / stdlib / unknown edges are counted in a summary histogram but -never trigger findings — their ABI is not statically visible. - -## 4. Phase 2 — Type & control-flow verifiers (~600 LOC) - -### 2.1 FFI type-boundary edge - -Extend each language Visitor (`c_visitor`, `rust_visitor`, `js_visitor`, `python_visitor`, -`swift_visitor`, `go_visitor`, `java_visitor`) to emit a `kind=FFIBoundary` record -when parsing `extern`/`JNIEXPORT`/`PyMethodDef`/`napi_*`/`#[no_mangle]`/`cgo` declarations. -The record carries: - -| Field | Source | -|-------|--------| -| `callee_language` | opposite end of the boundary (heuristic: file language vs. declared extern language) | -| `callee_signature` | tree-sitter `parameter_list` subtree, raw text | -| `ownership_kind` | `none`/`borrow`/`transfer` (Rust `&mut`/`Box::into_raw`/`ManuallyDrop`; C `free`/`malloc`; JS `napi_create_*`) | - -Schema migration: add `kind=FFIBoundary` to the `RecordKind` enum, plus two columns -`callee_signature TEXT`, `ownership_kind TEXT` on `semantic_records`. Reuses the same -migration pattern as `resolve_strategy` (see `store_schema.cpp:921-994`). - -### 2.2 Type-mismatch verifier - -`verify/ffi_type_verifier.cpp` — for each `FFIBoundary` record, compare the two -signatures via a per-language type-map table (`c ↔ rust ↔ js ↔ python`): - -| C | Rust | JS (napi) | Python (PyMethod) | -|---|------|-----------|-------------------| -| `int32_t` | `i32` | `number` | `int` | -| `char*` (out) | `CString` | `string` | `str` | -| `void*` | `*mut c_void` | `unknown` | `int` (capsule) | - -Mismatch → `Finding{rule="ffi_type_mismatch", severity=error}`. The type-map lives -in `engine/src/verify/ffi_type_map.h` as a `constexpr` table — no runtime DB. - -### 2.3 Panic-crossing verifier - -`verify/ffi_panic_verifier.cpp` — statically scan the body of every `extern "C"` -function (C++) and every `unsafe extern "Rust"` block (Rust). If the body contains -`throw`/`panic!`/`unwrap`/`expect`/`unreachable!` and the function is on an FFI edge, -emit `Finding{rule="ffi_panic_cross", severity=error}`. - -Reuses: Visitor CallExpr scan already enumerates these; add a body-walk pass gated -on `kind=FFIBoundary`. - -## 5. Phase 3 — Ownership & lifecycle (~800 LOC) - -### 3.1 Ownership-transfer edge - -Stamp `ownership_kind=transfer` on every FFI record where one side releases and -the other acquires (Rust `Box::from_raw`, C `free` after Rust `into_raw`, JS -`napi_delete_reference`). Track the pair via `reference.resolve_strategy` chain. - -### 3.2 Use-after-free across boundary - -Reuse the call graph: if a symbol S is `free`-called on the C side and then -referenced on the Rust side after the free (call-graph predecessor edge), emit -`Finding{rule="ffi_use_after_free", severity=error}`. This is the hardest check; -defer to Phase 3 unless Phase 2 surfaces a need. - -## 6. Test Plan (per `plan/rules/code_rules.md` §4) - -| Phase | Fixture | Asserts | -|-------|---------|---------| -| 1.1 | `tests/ffi/undefined_decl.{c,rs}` — `extern` with no body | 1 `ffi_undefined_decl` finding | -| 1.1 | `tests/ffi/lang_mismatch.{c,rs}` — C decl vs JS body | 1 `ffi_lang_mismatch` finding | -| 1.2 | MCP `initialize` twice on same `rootPath` | reuses `project_id`, no empty shell | -| 2.2 | `tests/ffi/type_mismatch.{c,rs}` — `int32_t` vs `i64` | 1 `ffi_type_mismatch` finding | -| 2.3 | `tests/ffi/panic_cross.cpp` — `throw` inside `extern "C"` | 1 `ffi_panic_cross` finding | -| 3.2 | `tests/ffi/uaf.{c,rs}` — free then use | 1 `ffi_use_after_free` finding | - -Each fixture is a 20–40-line real project; integration tests use real sqlite -(no mocks), per §4 "Integration tests must use real dependencies." - -## 7. Roll-out - -| Phase | LOC | New files | Risk | -|-------|-----|-----------|------| -| 1 | ~230 | `ffi_resolver_verifier.cpp`, small `engine_ffi.cpp` edit | Low — reuses existing SQL | -| 2 | ~600 | `ffi_type_verifier.cpp`, `ffi_panic_verifier.cpp`, `ffi_type_map.h`, 7 Visitor edits | Medium — schema migration, multi-language visitor touches | -| 3 | ~800 | `ffi_ownership_verifier.cpp` | High — call-graph predecessor walk | - -Review gate between phases: Phase 2 cannot start until Phase 1 ships and the type-map -table is reviewed for correctness (the table is the single source of truth for every -mismatch verdict — a wrong row means wrong findings). - -## 8. Non-goals - -- No type inference across the whole project (no Hindley-Milner, no flow typing). -- No ABI-layout check (struct member offsets, padding) — that needs a separate - compiler-rt / libclang tool, out of scope. -- No runtime FFI hooking (LD_PRELOAD, frida) — static only. -- No replacing `engine_detect_ffi_boundaries`; the new verifiers sit on top of its - output, never re-implement the boundary scan. -- **No third-party / stdlib callee analysis.** Verifiers only fire on edges where - `is_in_project == true` on BOTH ends (see §3.1 decision rule). Third-party / stdlib - / unknown callees are tallied in a summary histogram but never produce findings — - their ABI is not statically visible and would cause false positives. -- **No cross-function UAF (Phase 3) until control-flow analysis exists.** Static - call-graph has topology only, no time order. Cross-function ownership transfer is - tallied as "suspicious" not "bug" until a control-flow pass is added. - -## 9. Independent storage schema — FFI analysis isolation - -FFI detection data is stored in a **separate SQLite table group** from the main -analysis (semantic_records / graph_edges / entity / modules). Rationale: -- FFI findings are append-only and idempotent — re-running a verifier replaces only - its own rows, never touches the main analysis tables. -- Schema migration is independent — adding a Phase 3 verifier does not force a - rebuild of the main call graph. -- Query surface is narrow — only `engine_get_ffi_findings` / `engine_ffi_summary` - read these tables; no risk of join explosion with the main tables. - -### 9.1 Tables - -All tables live in the same SQLite DB (the per-project `*.db` file). They are -prefixed `ffi_` to make the namespace explicit and to allow `ATTACH`/`DETACH` for -future per-language FFI DB sharding without name collisions. - -```sql --- ───────────────────────────────────────────────────────────────────── --- ffi_boundary: one row per FFI boundary symbol discovered by the --- boundary scan (the persistent form of engine_detect_ffi_boundaries --- output).

Never - one INSERT per finding (would be thousands of FFI round-trips). -- **Idempotent re-scan**: each verifier begins `DELETE FROM ffi_findings WHERE - project_id=? AND verifier=?` inside the same transaction as its INSERT batch. - No partial state visible. -- **Error handling**: every `sqlite3_prepare_v2` failure emits a - `[module=verify, method=] prepare failed: %s` stderr line and returns - a non-zero error code. No silent skips. -- **No git commit** during development; tables are created lazily by the first - verifier run, not by the global `createSchema` migration — keeps the main schema - stable. - -### 9.3 Query surface - -Only two engine entry points read these tables: - -| API | SQL | Returns | -|-----|-----|---------| -| `engine_get_ffi_findings(project_id, severity_filter)` | `SELECT * FROM ffi_findings WHERE project_id=? AND severity IN (?)` | JSON array of findings | -| `engine_ffi_summary(project_id)` | `SELECT * FROM ffi_scan_summary WHERE project_id=?` | JSON histogram per verifier | - -Both reuse the existing `jsonEscape` + `sqlite3_bind_*` pattern from -`engine_queries.cpp`. No new FFI escape rules. - -### 9.4 Why not reuse `verify_findings` (the existing verifier output table)? - -The existing `verify/` registry writes to `verify_findings` (generic, one row per -finding across all verifiers — dead_code, doc_drift, etc.). FFI findings are kept -separate because: - -1. **Volume** — a single C/Rust project can have thousands of FFI boundaries; mixing - with dead-code findings would bloat `verify_findings` and slow every generic - verifier query. -2. **Lifecycle** — FFI findings expire on re-scan of the boundary table; generic - verifier findings expire on re-index. Different invalidation windows. -3. **Joins** — `ffi_findings.boundary_id` joins to `ffi_boundary`, which joins to - `entity` for the callee signature. Keeping these in the `ffi_*` namespace makes - the join graph explicit and prevents cross-pollination with generic verifier - joins. - -## 10. Open Questions (for review) - -1. Should `kind=FFIBoundary` reuse the existing `RecordKind::CallExpr` (kind=9) with - a new `call_kind` value, or be a distinct kind? Distinct kind is cleaner but forces - a `semantic_records` migration; reuse is cheaper but pollutes the call-edge stats. -2. The type-map table — auto-generated from cbindgen / ts types or hand-maintained? - Hand-maintained is correct today; auto-gen is a Phase 4 ask. -3. `ffi_panic_verifier` body-walk needs the full function body text. Today Visitors - only capture `start_row/start_col/end_row/end_col` — do we store body text, or - re-read the source file at verify time? Re-read is simpler and bounded by file size. diff --git a/docs/dev_plans/role_classifier_plan.md b/docs/dev_plans/role_classifier_plan.md deleted file mode 100644 index 34601e9..0000000 --- a/docs/dev_plans/role_classifier_plan.md +++ /dev/null @@ -1,220 +0,0 @@ -# Role Classifier 升级计划从机械路埄关键字到倚信号融合 -
