fix(dart): a bare call stays in the class hierarchy (#2145)
A receiver-less Dart call now reaches only a method of the enclosing class, something it extends / mixes in / implements, or an extension on one of those types, and the nearest one wins. The hierarchy is read from each declaration's head (comments and type arguments dropped), since supertype edges don't exist on the first pass. Body-less abstract members (extracted as owned functions) are scoped too. Mixin-application classes (`class A = B with C;`) were extracted as `<anonymous>` with no supertypes; both the wasm extractor and the Rust kernel now name them and emit their extends/implements refs (kernel parity verified on bloc, riverpod, shelf, dio, getx). A/B (edges removed / added): riverpod -1945/+517, shelf -785, getx -855/+18, bloc -178/+95, dio -78. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

fix(extraction): preserve symbols with colliding same-line IDs (#1349) (#2030)
Same-kind, same-name declarations on one line shared an ID and silently overwrote each other in SQLite. Use per-extraction collision tracking to append a UTF-16 column only to later distinct declarations. Apply the same rule across wasm, Rust language walkers, Liquid, and CFML while preserving file IDs and edge endpoints. Add persistence, call-edge, identity-vector, and Unicode parity regressions.

fix(dart): index a Dart 3 extension type as the type it is (#1784) (#1865)
`extension_type_declaration` appears in none of the three places Dart's other type-like declarations do. `extension_declaration` — the older `extension` — is in all three, and the two names are near neighbours. That is why #1780's `isInsideClassLikeNode()` gate dropped these members and no others: the gate asks whether a class-like node is on the stack, and an `extension type` never put one there, while `extension`, `mixin` and `class` all did. The gate surfaced the omission rather than causing it. Before it, the members were still reached — but as top-level `function:km` rather than `method:MetersT::km`, indexed and attributed to nothing. The kernel omits the same node type, so it walks the members through its own fallback and mints them as top-level functions with no `MetersT` to belong to. `kernel-dart-parity.test.ts` fails four cases on `main` because of it; fixing only the wasm side would leave those red. Listing it alongside the others is the whole fix — `extraClassNodeTypes` and `dartEnclosingTypeName` on the wasm side, the two `matches!` arms on the kernel's. Both paths now give: class:MetersT · method:MetersT::km · method:MetersT::report with `report`'s span running to its closing brace rather than stopping at the signature line, and an ordinary class untouched. |

fix(kernel): guard the native walkers against stack overflow and defer deep files to wasm (#1581) (#1600)
Fixes #1581.
## What was wrong
`codegraph init` / `codegraph index` died with `Segmentation fault` — the whole CLI
process, not a parse worker — on a C/C++ file with very deep brace nesting (llvm's
`clang/test/Parser/parser_overflow.c`, 16,384 nested `{`). The reporter's diagnosis is
exactly right: tree-sitter's parser is iterative, so the file parses fine, and then the
native kernel's **recursive walker** (`visit_node` → `visit_for_calls_and_structure` → …,
one frame per AST level) overflowed the thread's stack. A native overflow can't be caught
the way a wasm abort can, and a parse worker is a thread of the `codegraph` process, so
the SIGSEGV took the entire indexer down — no message, no per-file fallback, no partial
index.
Two things made "just give the worker a bigger stack" the wrong fix:
- it only moves the cliff — reproduced here: the reporter's 16,384-deep file kills a
default 4 MiB worker (rc=132 on macOS / 139 on Linux), and a 100k-deep file kills the
8 MiB **main** thread too;
- the walkers are shared by every kernel-routed language (20 of them), and each has
several recursion points with different frame sizes, so no single stack size is a
provable bound.
Meanwhile the wasm path already handles this shape gracefully: its JS walker catches its
own `RangeError` per file and stores a partial result with a `parse_error`. The kernel
just needed a way to get there instead of dying.
## What this does
**The kernel guards its own recursion against the calling thread's real stack bounds and
defers a too-deep file to wasm** — the same `defer:` routing signal it already uses for
files with parse errors, which `src/extraction/kernel/index.ts` treats as "take the wasm
path for this file", silently.
- `codegraph-kernel/src/stack.rs`: per-thread stack bounds from the OS, computed once per
thread and cached — glibc/musl `pthread_getattr_np` + `pthread_attr_getstack`, macOS
`pthread_get_stackaddr_np` + `pthread_get_stacksize_np`, Win32
`GetCurrentThreadStackLimits` (a hand-declared `kernel32` extern; no `windows-sys`).
`exhausted()` is one thread-local load and one compare: true once the stack pointer is
within a 256 KiB red zone of the limit, and it latches a flag. Where the OS can't report
bounds it falls back to a fixed 1 MiB descent budget measured from the entry stack
pointer — safe on anything from Node's 4 MiB worker default up. So the guard is exact on
the 4 MiB worker, the 8 MiB main thread, and any `resourceLimits.stackSizeMb` alike.
- `stack_guard!()` (defined in `lib.rs`) is the first statement of every recursive walker
function — all **150** self-recursive or on-cycle functions across the 15 walker modules,
found by script (every cycle in the call graph, not just direct self-calls). It returns
`Default::default()` (`()`, `false`, `None`, `""`) so an exhausted walk simply stops
descending; a hook returning `false` sends its caller down the generic child walk, whose
own guard returns at once.
- `extract_file` runs the whole walk under `stack::run_guarded`: if the flag is set
afterwards the (truncated) result is discarded and replaced by
`defer: nesting too deep for the native walker — wasm recovery handles it`.
- `parse-pool.ts`: a comment at `new Worker(scriptPath)` records why there is deliberately
no `resourceLimits.stackSizeMb` bump.
- No new crates beyond `libc` as a direct unix dependency (already in `Cargo.lock`
transitively). No wire/ABI change.
Net effect for the reporter's repo: `deep.c` goes to the wasm path, lands as
`function foo` plus a recorded parse warning, and the other 31,607 files index normally.
`CODEGRAPH_KERNEL=0` and the `exclude` workaround are no longer needed.
## Tests
**Rust unit tests** (`cargo test`, 21 passed — 7 new in `stack.rs`): the walkers for
C, C++, Rust, TypeScript and Python are driven on a **1 MiB** thread (a quarter of Node's
worker default) with 30k-deep nesting and must return `defer:` instead of crashing;
shallow files are untouched; the latch resets between runs; the OS bounds are sane on the
main thread and describe a small thread's own stack.
**`__tests__/kernel-deep-nesting.test.ts`** (new, 8 tests — skips without a staged `.node`,
fails under `CODEGRAPH_KERNEL_EXPECT=1` if the kernel is missing, like the other kernel
suites):
- every default-routed language (all 20) survives a 60k-deep expression on the main thread
— clean result or the wasm fallback's partial result, never a crash;
- the reporter's exact 16,384-brace C file is indexed (partial) on the main thread;
- 200-deep expressions in every language still take the kernel path clean (the guard never
trips on normal code);
- inside a **default-sized 4 MiB `worker_threads` Worker** through `dist/`: the reporter's
`deep.c` and a 60k-deep expression in every language come back `deferred` with exit 0,
and a normal file still extracts natively;
- end-to-end through the built CLI: `codegraph init` on a repo holding `deep.c` + `ok.c`
exits 0 and records both files, with both functions.
**Existing kernel suites**: all 15 (`kernel-*-parity`, `kernel-scaffold`,
`kernel-retry-materialize`, `kernel-grammar-parity`) pass unchanged, 147 tests — the guard
never fires on the parity fixtures.
**Reporter's probes** (`one.js` from the issue, default 4 MiB worker, this build):
`deep.c` → `deferred`, exitCode=0 (was rc=132/139); `deep100k.c` → `deferred`, exitCode=0.
Main thread: `deep.c` / `deep100k.c` → wasm partial with
`Parse error: Maximum call stack size exceeded`; a 6,000-term binary expression and a
3,000-branch `else if` chain stay on the kernel path with clean results.
**Perf** (same `dist/`, only the `.node` swapped via `CODEGRAPH_KERNEL_PATH`; interleaved
main/new ×3, `codegraph init`, macOS arm64):
| repo | main (median) | guarded (median) | nodes / edges |
|---|---|---|---|
| express (141 files) | 0.60 s (0.58–0.65) | 0.61 s (0.58–0.61) | 1,084 / identical |
| redis (786 C/H files) | 4.44 s (4.39–4.66) | 4.49 s (4.41–4.70) | 19,942 / 76,446 identical |
Within run-to-run noise, as expected for one TLS load + compare per recursion entry.

feat(kernel): R7b Dart walker — dart module, vendored-grammar-C d4d8f3e + wasm byte-copy vendor, dart default-routed (#1386)
R7b batch 4 #4 — the FINAL R7b language (docs/design/dart-kernel-port-checklist.md is the authoritative quirk list). The fourth vendored-grammar-C language, with a twist: production dart resolved its wasm from tree-sitter-wasms, whose dart dependency is an UNPINNED github:UserNobody14/tree-sitter-dart — a routine dependency update would have silently changed dart's grammar. This PR byte-copies the shipping 0.1.13 artifact into src/extraction/wasm/ (VENDORED_WASM_LANGS += dart) and compiles the same-commit (d4d8f3e337d8) parser.c/scanner.c in the kernel — table identity proven by the kernel-grammar-parity row. crates.io tree-sitter-dart is the nielsenko fork (different lineage) — rejected. The center of gravity is THE SIBLING-BODY DOUBLE-WALK, reproduced bug-for-bug: dart attaches every function/method body as a NEXT SIBLING of its signature, and the TS walkers consume each body TWICE — once via resolveBody (attributed to the function/method) and once via the enclosing generic walk (attributed to the file/class). Duplicate local-function nodes with the SAME id under different parents, duplicated calls/instantiates refs, and file/class-attributed fn-ref twins all emit in the exact observed interleave (a dedicated fixture pins the duplicate-id rows; the bloc kind-census spot-check pins the counts). Also preserved (probe-pinned): the extractBareCall selector matrix (the first callTypes=[] language — cascades completely invisible, `?.` encodes like `.`, the `ConfigT.load()` calls+references double emission with no callee-of-call skip, capitalized-chain `Foo.create().run` re-encode, const-object callee names); the constructor hooks (unnamed ctor skipped, named ctors/factories renamed to the CTOR name with the class as returnType, `@override (T) m()` record-misparse rescued by class-name validation); operator methods minting `method "<anonymous>"`; static_final_declaration constants via the visitNode hook while instance fields mint NOTHING; the prefixed-return-type prefix bug (`other.OtherClass f()` → returnType `other`); enum `with` mixins silent vs `implements` working; anonymous extensions named after the ON type; deferred imports invisible; named-argument callbacks NOT fn-ref-captured (the Flutter `onPressed:` idiom — future accuracy PR, TS-side first); `async*`/`sync*` NOT async; value-refs with the LIVE dart sibling-body pull and the `$X`-vs-`${X}` interpolation asymmetry; dartdoc kept in all three comment forms with the annotation-broken chain. Gates: parity sweeps first-run 0-diff on shelf/bloc/flutter — 5,815 clean files byte-parity, deferrals 10/21/1341 ≈ the survey's 10/21/~1340 (both-arm grammar reality: empty object patterns — the sealed-class idiom — and unnamed `library;` dominate; --max-deferral 0.3); full-init dumps byte-identical ×3 (shelf 7,959 / bloc 40,026 / flutter 1,855,319 dump lines); bloc per-kind node census identical across arms (the double-walk duplicate rows survive the store identically); kernel-dart-parity suite (7 fixtures + in-memory CRLF variants + double-walk duplicate-id pin + generated-file skip pin + two defer pins); full suite 2,688 green ×2 with CODEGRAPH_KERNEL_EXPECT=1. DEFAULT_ROUTED += dart (20 langs — R7b COMPLETE). Co-authored-by: Claude Fable 5 <noreply@anthropic.com> |
