Root every such copy through a RuntimeHandleScope and re-read the current (possibly relocated) value before each dispatch, instead of trusting the pre-call copy. Reproduced at crates/perry-runtime/src/node_stream_event_emitter.rs's emit_stream_event/call_listener_args (the path `class X extends EventEmitter` actually dispatches through): a 3-listener emitter whose second listener allocates heavily segfaults dereferencing the third listener's stale closure pointer, reliably, with no GC env knobs.

For a CommonJS module, cjs_wrap::wrap_commonjs_for_target wraps the whole body as text inside a `function __perry_cjs_factory() {...}` closure nested in an anonymous IIFE; hir.init ends up with only a handful of wrapper statements, so admission never fired and the real body stayed one giant function. On typescript 5.9.3's _tsc.js this was a single 463,716-instruction/6.30 MB closure, past the machine-pipeline budget. find_cjs_factory_closure(_mut) locates that closure by walking hir.init's statement/expression tree (it is a Stmt::Let naming an Expr::Closure, not a hir.functions entry, since it is lexically nested). outline_entry_module now tries hir.init first (unchanged #8595 behavior) and falls back to the factory's body with the identical chunk_statements/analyze_stmts_outlining machinery, so a module is only ever outlined from one origin per compile. The factory always captures its own name from the wrapper's IIFE scope (`__cjs_module.__perry_cjs_factory = __perry_cjs_factory;`, which perry-runtime's module_require.rs calls through on a circular-require recovery path). A chunk is a plain, non-capturing function and can't read a captured id, so classify_for_chunking keeps any statement referencing one inline in the residual body rather than promoting it to a module global -- a global would turn a per-invocation-fresh capture into one program-wide instance and could silently break that recovery path. module_globals_emit.rs folds the factory's own logical statements into the same cross-chunk-let promotion emit_module_globals already does for hir.init, so a var shared across the factory's new chunks gets the same @perry_global_* treatment hir.init cross-chunk lets get. Verified on a synthetic 2107-statement CJS fixture (cross-chunk vars plus a closure created early and invoked from far-later statements) against Node's own output, and on a full typescript 5.9.3 build: the 463,716-instruction closure is gone, entry-outline reports "cjs factory: ... candidate=true", nm shows __perry_entry_chunk_* symbols, and `--noEmit demo.ts` / `--version` output and exit codes are byte-identical to before. --- .../src/codegen/entry_outline.rs | 967 ++++++++++++++++-- .../src/codegen/module_globals_emit.rs | 9 +- 2 files changed, 899 insertions(+), 77 deletions(-) diff --git a/crates/perry-codegen/src/codegen/entry_outline.rs b/crates/perry-codegen/src/codegen/entry_outline.rs index 1382421208..d77cba26eb 100644 --- a/crates/perry-codegen/src/codegen/entry_outline.rs +++ b/crates/perry-codegen/src/codegen/entry_outline.rs @@ -1,4 +1,4 @@ -//!

Node refresh() reschedules only and never touches ref state; drop the forced ref-state write and let the existing entry (set at schedule time, updated by any ref()/unref() since, pinned while the timer is queued) stand. js_number_coerce gave setImmediate handles the same numeric-conversion shortcut as Timeout handles, so +setImmediate(...) returned a number instead of NaN. Node only gives Timeout (setTimeout/setInterval) a numeric conversion; Immediate has none.

Two representations, two gaps: the Web Fetch family and TextEncoder/ TextDecoder are small-integer registry handles with no brand/property case; URL/URLSearchParams and AbortController/AbortSignal/EventTarget/ Event/CustomEvent are real objects whose instances are never linked to their .prototype via object_static_prototype, so a property installed only there would never be reached from an instance. A new web_builtin_to_string_tag answers both Object.prototype.toString and x[Symbol.toStringTag] from one place, and a real, correctly-shaped descriptor is also installed on each constructor's own .prototype for reflection.

Lowering +represents that lexically-nested declaration the way it does any function +*expression* — a `Stmt::Let` naming an `Expr::Closure` inside `hir.init`'s own +expression tree, not a `hir.functions` entry — leaving `hir.init` itself with +only the handful of statements the wrapper adds at module scope (the `_cjs` +binding, `export default`, …). Automatic admission needs 1,000 top-level +statements or 4,000 estimated safepoints, so it could never fire on CJS no +matter how large the module was. On `typescript@5.9.3`'s `lib/_tsc.js` the real +body therefore stayed a single 463,716-instruction / 6.30 MB closure — past the +100,000-instruction optimized machine-pipeline budget, so the whole unit was +emitted through LLVM's O0 machine pipeline — and the linked binary contained +zero `__perry_entry_chunk_*` symbols. + +`find_cjs_factory_closure`/`find_cjs_factory_closure_mut` locate that closure by +walking `hir.init`'s statement/expression tree. `outline_entry_module` now tries +`hir.init` first (unchanged #8595 behaviour) and, only if that is not a +candidate, falls back to the factory's body using the *identical* +`chunk_statements`/`analyze_stmts_outlining` machinery: same admission +thresholds, same fail-safe gates (top-level await, TDZ preallocation), same +`__perry_entry_chunk_*` naming, and each chunk still carries its origin body's +strictness. A module is only ever outlined from one origin per compile, +`hir.init` or the factory, never both. The factory is treated as a virtual +module entry only when it has the exact wrap-generated shape — no params, not +async, not a generator, and every id it captures resolving to a `Let` directly +in the enclosing IIFE — so failing the shape check is a defensive exit rather +than an expected one. + +The one new concept is must-stay ids. The factory always captures exactly one id +from its enclosing scope: its own name. The preamble that opens the factory's +own body builds `const __cjs_module = { …, __perry_cjs_factory: +__perry_cjs_factory, … }`, a load-bearing self-reference that `perry-runtime`'s +`module_require.rs` reads back off the CJS record and invokes with +`js_closure_call0` on an already-loaded re-require path. A chunk is a plain, +non-capturing `hir.functions` entry and cannot read a captured id the way the +original closure could, so `classify_for_chunking` keeps any statement +referencing a captured id inline in the residual body, never relocating it into +a chunk, preserving the exact closure-capture codegen already emitted for it. +This is deliberately *not* solved by promoting the captured id to a module +global the way a cross-chunk `hir.init` let is: a global is one program-wide +instance, but a closure capture is fresh per invocation, so promoting it would +silently change re-invocation semantics on that recovery path. `hir.init`'s own +outlining passes an empty must-stay set, which short-circuits, so this is a +no-op for every non-CJS module. Alongside it, `emit_module_globals` folds an +outlined factory's logical statements into the same cross-chunk promotion it +already does for `hir.init`, so a `var` shared across the factory's new chunks +gets the same `@perry_global_*` treatment a cross-chunk `hir.init` `let` gets. + +Measured on the issue's own repro, a full `typescript@5.9.3` build: the linked +binary now carries real chunk-derived symbols (`…_entry_chunk_…_0` through +`_19`, plus wrapper trampolines) where none existed before, and the single +463,716-instruction closure no longer appears anywhere in the build log. +Behaviour is unchanged — `--noEmit` over a type-error fixture is byte-identical +to `node node_modules/typescript/lib/_tsc.js` with the same exit code, and +`--version` still reports 5.9.3. + +Honest caveat on size for this particular input: two individual chunks are still +around 190k and 396k instructions (down from one 463,716-instruction +whole-factory function), because a few of `_tsc.js`'s top-level statements are +themselves large enough to remain oversized even isolated into their own chunk — +sub-statement granularity is not attempted here — and the linked binary grew +from 86.4 MB to 100.0 MB, since ~20 function prologues and their GC-safepoint +scaffolding are not fully offset while a couple of chunks still hit the O0 +fallback. Correctness is unaffected either way. A synthetic CJS fixture without +`_tsc.js`'s size-outlier statements went 11.0 MB → 9.2 MB and escaped the O0 +fallback entirely. + +Validated with `cargo test -p perry-codegen --lib` (1,598 passed), including +five new `entry_outline` tests: factory-shape matching and rejection +(param/async/generator/unresolvable-capture/wrong-name/no-wrapper), factory +outlining when `hir.init` is not a candidate, `hir.init` still winning when both +sides independently qualify, the self-reference-capture-stays-inline invariant, +and declining cleanly when neither side qualifies. The regression was proved +reachable rather than assumed: against pristine `origin/main`, a synthetic +1,200-statement CJS-factory-shaped module returned `Skipped("below automatic +outlining threshold")`. A synthetic 2,107-statement CJS fixture (cross-chunk +`var`s plus a closure created early and invoked from far-later statements) +produced output matching Node's own execution of the same file exactly, both +with outlining forced on and under `PERRY_OUTLINE_ENTRY=0` — where the disable +path reproduces the original 211,164-instruction / O0 pathology, confirming the +kill switch still works. `cjs_wrap_builtin_require` and +`issue_4872_barrel_default_reexports` pass unchanged, confirming small and +ordinary CJS modules are unaffected.

Perry's forced write meant `hasRef()` flipped back to `true` on refresh, so the timer kept the process alive and eventually ran a callback the program had deliberately detached from the event loop. The fix drops both forced writes; the id's ref-state entry (set at schedule time, updated by any `ref()`/`unref()` call since, and pinned by `ScheduledTimerId` while the timer is queued, per #10447) is left alone. + +`js_number_coerce`'s timer-handle numeric-conversion shortcut (`+t` → the handle's internal id) was gated only on `is_known_timer_id`, which is true for both `Timeout` and `Immediate` handles.

Added `crate::timer::is_immediate_timer_id`, a thin wrapper over the existing kind registry, and gated the shortcut on it; an `Immediate` now falls through to the pre-existing generic `toPrimitive`/`toString` path, which already stringifies to `"[object Object]"` and coerces to `NaN` — that path was simply unreachable for timer handles before. + +Validation: new gap test `test_gap_10541_10542_timer_refresh_ref_immediate_primitive` matches Node 26.5.1 byte for byte and reproduces both bugs on the pre-fix build (an unref'd timer re-refs after `refresh()` and its detached callback fires; `+immediate` is a number, not `NaN`).

Finding that out costs ~206 instructions per object: iterator construction (61), the descriptor body (127), the worklist push, and the drain entry with its cold header read. `gc_object_yields_no_child_slots` answers the question from the header word the caller has already loaded, so those objects are never pushed. Three of the four terms fold into one mask compare on `_reserved`; the term order is measured rather than chosen, and the comment says so. Measured with `perf stat -e instructions:u`, min-of-5, same SHA in both arms: gc3 -7.10%, w20000 -5.75%, w5000 -4.70%, leafarr -4.22%, w1000 -2.25% Call counts, per consumer: copying minor 2,800,337 -> 1,520,316 (-45.7%) full mark 2,400,630 -> 1,200,319 (-50.0%) remembered-set rebuild 980,690 -> 490,345 (-50.0%) Peak RSS on gc3 -4.4%, from the smaller worklist. Collection counts are identical on all seven fixtures, so this perturbs no pacing. Three fixtures regress: oldyoung +0.11%, dist16_ptr +0.12%, rec16_ptr +0.06%. This is structural, not noise. The predicate costs O(traced objects) while the win is O(qualifying objects), and oldyoung's pointer-free population is objects rather than arrays -- they pass the mask compare, fail the type test, and so pay both terms while qualifying for neither. In the full mark the skip is additionally gated on proxy tracing being inactive. A pointer-free payload is still handed to gc_observe_traced_value while a proxy is being traced, so skipping it there would collect a live proxy's target. The minor and the rebuild are unconditional; that asymmetry is deliberate. --- crates/perry-runtime/src/gc/copying.rs | 14 +- crates/perry-runtime/src/gc/layout.rs | 70 ++++++ .../src/gc/tests/layout_trace.rs | 20 +- crates/perry-runtime/src/gc/tests/mod.rs | 1 + .../src/gc/tests/zero_slot_skip.rs | 230 ++++++++++++++++++ crates/perry-runtime/src/gc/trace.rs | 56 ++++- crates/perry-runtime/src/gc/verify.rs | 6 + 7 files changed, 390 insertions(+), 7 deletions(-) create mode 100644 crates/perry-runtime/src/gc/tests/zero_slot_skip.rs diff --git a/crates/perry-runtime/src/gc/copying.rs b/crates/perry-runtime/src/gc/copying.rs index 7a510d1d64..54751c82cc 100644 --- a/crates/perry-runtime/src/gc/copying.rs +++ b/crates/perry-runtime/src/gc/copying.rs @@ -608,7 +608,19 @@ impl CopyingNurseryCollector { (*header).gc_flags &= !GC_FLAG_MARKED; gc_type_after_payload_move((*header).obj_type, old_user as usize, new_user as usize); - self.worklist.push(new_header); + // #10362: an object that provably yields no child slot is marked and + // moved, but not QUEUED — the drain would build an iterator and find + // nothing.

A new sibling of str_bytes_from_jsvalue, str_bytes_ascii_from_jsvalue, computes the bit once and threads it through; bytes_all_ascii itself switches from a byte-at-a-time loop to <[u8]>::is_ascii() (word-at-a-time, total over arbitrary byte strings). An earlier version of this change also tried to read a heap string's ASCII-ness straight off its header (utf16_len == byte_len, free) instead of scanning at all. That is unsound and was caught in review before landing: Perry heap-string payloads are not guaranteed valid UTF-8 (WTF-8 lone surrogates, Buffer.toString of arbitrary bytes, FFI blobs - #6085), and a payload ending in a truncated multi-byte lead byte can coincide on utf16_len == byte_len without being ASCII (compute_utf16_len_wtf8 charges a truncated lead its full nominal unit count while the payload holds fewer bytes than that sequence declares - string/compare.rs's utf16_cmp_bytes doc names the identical hazard). The header check survives only as a negative filter (utf16_len != byte_len soundly proves non-ASCII, unconditionally, not just for well-formed input); utf16_len == byte_len is ambiguous and always falls back to a real scan. js_string_concat_value's memo-admission gate had the identical exposure independently and is fixed the same way. No TypeScript-reachable path that constructs such a payload was found: Buffer.toString (all seven encodings), TextDecoder.decode, and every bun:ffi string-returning path all validate via str::from_utf8/from_utf8_lossy (or are fed a Rust &str, valid by construction) before ever calling js_string_from_bytes. The fix stands regardless, since js_string_from_bytes is a pub extern "C" entry point whose own contract must hold for any bytes. Regression tests are therefore Rust-level against hand-built malformed StringHeaders (the same technique string/compare.rs's own corpus and tests_guard_page.rs already use) rather than a gap test - all three fail against the reverted code, confirmed by temporarily reintroducing it. The short-concat memo's probe also assembled both operands into a stack buffer just to hand the hash/lookup helpers one contiguous slice. FNV-1a is a streaming hash and the byte compare can run in two parts, so concat_memo_hash_parts / concat_memo_slot_and_tag_parts / concat_memo_lookup_parts replace the buffer with direct two-slice hashing and lookup; the single-slice js_string_concat_value memo probe now goes through the same two-slice primitives. The memo probe's own break-even hit rate (governed by the probe's hash/lookup/admit cost, not by the ASCII-determination fix) barely moved: ~54% before this fix, ~50.6% after, both measured by forcing the governor on/off via a temporary env knob (since removed). MEMO_MIN_HIT_SHIFT stays 1 (50%, still the closest power-of-two floor to either number) - it moved from the original 2 (25%, never measured) in this same change. Measured (differential instruction-count probe, bare-loop control flat in both arms, base and arm built in the same session): 640-distinct short concat 548 -> 403 instructions/concat (-26.5%), a 73-byte memo-ineligible concat 644 -> 471 (-26.8%), a 100%-memo-hit workload 319 -> 318 (unchanged, within noise).

FNV-1a is + a streaming hash (`fnv(a ++ b)` needs no buffer, just fold `a` then `b`), + and the byte compare on a hit/miss can run in the same two parts against + the cached entry. `concat_memo_hash_parts` / `concat_memo_slot_and_tag_parts` + / `concat_memo_lookup_parts` replace the buffer with direct two-slice + hashing and lookup; the single-slice `js_string_concat_value` ("prefix" + + i) memo probe is now implemented in terms of the same two-slice + primitives. + +**An earlier version of this change also tried to skip the scan entirely**, +by reading a heap string's ASCII-ness straight off its header (`utf16_len == +byte_len`, already computed at construction, so free). That is unsound, and +was caught in review before landing: Perry heap-string payloads are not +guaranteed valid UTF-8 (WTF-8 lone surrogates, `Buffer.toString` of +arbitrary bytes, FFI blobs — #6085), and a payload ending in a truncated +multi-byte lead byte can coincide on `utf16_len == byte_len` without being +ASCII — `compute_utf16_len_wtf8` charges a truncated lead its full nominal +unit count while the payload holds fewer bytes than that sequence declares +(`[0xC3]`, a lone 2-byte lead, records `utf16_len == 1 == byte_len`; +`string/compare.rs`'s `utf16_cmp_bytes` doc names the identical hazard and +pins the identical corpus for its own ASCII fast path — this change's +`str_bytes_ascii_from_jsvalue` doc now cross-references it). The header +check survives only as a NEGATIVE filter: `utf16_len != byte_len` soundly +proves non-ASCII with no scan needed, because `compute_utf16_len_wtf8` +counts exactly one unit per byte for any run of bytes `< 0x80` — the +contrapositive holds unconditionally, not just for well-formed input — but +`utf16_len == byte_len` is ambiguous and always falls back to a real +`is_ascii()` scan. `js_string_concat_value`'s memo-admission gate had the +identical exposure independently: `prefix_u16 == prefix_blen` was treated as +sufficient on its own and the `bytes_all_ascii` check right after it deleted +as redundant with it; restored, with the same negative-filter-then-scan +reasoning documented at the call site. + +No TypeScript-reachable path that constructs such a payload was found: +`Buffer.toString` (all seven encodings, `buffer/encode.rs`), +`TextDecoder.decode` (`text.rs`), and every `bun:ffi` string-returning path +(`read_cstring_value`, `dlopen.rs`'s `CString`/`cstring` conversions) all +validate via `str::from_utf8`/`from_utf8_lossy` (or are fed a Rust `&str`, +valid by construction) before ever calling `js_string_from_bytes` — `#609` +closed these same construction sites for a related UB hazard, and the fix +happens to guarantee well-formed output too. The fix stands regardless: +relying on an invariant this tree already documents as unsound is the wrong +foundation, and `js_string_from_bytes` is a `pub extern "C"` entry point +whose own contract must hold for any bytes, whether or not today's call +graph happens to always validate first. Regression tests are therefore +Rust-level, against hand-built malformed `StringHeader`s — the same +technique `string/compare.rs`'s own corpus and `tests_guard_page.rs` already +use — rather than a gap test: +`ascii_probe_falls_back_to_a_scan_when_the_header_lies`, +`concat_memo_declines_a_prefix_whose_header_lies_about_being_ascii`, +`concat_box_reports_not_well_formed_for_a_malformed_operand_either_side` +(`perry-runtime/src/string/tests.rs`) — all three fail against the reverted +(unsound) code, confirmed by temporarily reintroducing it and reverting +back. + +The memo probe's own break-even hit rate (governed by defect 3's mechanics — +hash/lookup/admit cost — not by the ASCII determination defects 1/2 changed) +barely moved between the unsound and sound paths: ~54% with the unsound +header shortcut, ~50.6% with the sound negative-filter-then-scan, both +measured by forcing the governor on/off via a temporary env knob (since +removed). `MEMO_MIN_HIT_SHIFT` stays `1` (50%, still the closest +power-of-two floor to either number) — it moved from the original `2` (25%, +chosen as a plausible fraction, never measured against the probe's own cost) +in this same change, which is what made the floor worth re-deriving at all. + +Covered by `test-files/test_gap_string_concat_memo_ascii_header.ts` +(byte-for-byte against node): ASCII boundary lengths crossing the SSO (5) and +memo (12) ceilings, 2/3/4-byte non-ASCII operands, a surrogate pair formed +*across* the join boundary and one that deliberately isn't (reverse order), +empty operands, and repeated-identical concats (both split two different +ways) to exercise the memo's "seen twice" admission and its `===` identity. +GC stress (`PERRY_GC_SCHEDULE_SEED=1` and `=42`, `RATE=1`, +`PROTECT_FROMSPACE=1`, `VERIFY_EVACUATION=1`, `FROMSPACE_SCAN_ABORT=1`) on a +concat-heavy fixture ran 117,923 copying minors and quarantined 14,739 +retired from-space sets with no fault and output still matching node, +confirming the memo's GC roots (`scan_concat_memo_roots_mut`) survive +evacuation under the new two-slice storage. diff --git a/crates/perry-runtime/src/string/concat.rs b/crates/perry-runtime/src/string/concat.rs index 3f4c1ef80f..ce30ed6839 100644 --- a/crates/perry-runtime/src/string/concat.rs +++ b/crates/perry-runtime/src/string/concat.rs @@ -104,15 +104,18 @@ pub(crate) fn canonicalize_surrogate_pairs(ptr: *mut StringHeader) -> *mut Strin /// True when the `len` bytes at `data` are all ASCII (`< 0x80`), or the slice /// is empty/null.

Broaden the classification to also cover a control-flow block (if/for/while/switch/catch/with/else/try/do/finally) and a braceless/operator equivalent (cond && require(...), cond ? require(...) : x, for (...) require(...) with no block) -- matching Node's actual 'loads only when control flow reaches it' semantics. An ordinary object literal, class body, or bare grouping block does not count (the common module.exports = { fs: require('fs') } barrel shape stays eager), and a process.platform === '' guard (node-pty's Windows/Unix terminal split) is exempted since the platform is a compile-time-known build target, not a runtime unknown. This was the sole remaining blocker compiling pg from source: pg crashed at init with Cannot find module 'pg-native' even though its guarding forceNative check was false.

Scalar replacement allocates a slot per declared field only, so `expr/property_get.rs`'s scalar arm found no slot and folded the read to the constant `undefined`. The effect was silent and order-dependent: const o = { a: 1 }; typeof o.toString // undefined, where node gives "function" o.toString() // correct — a fused call never consults the // elided object It reached `Object.prototype` members read as values (`toString`, `constructor`, `hasOwnProperty`), a class's own prototype method read as a value, and user-added `Object.prototype` properties. Anything that made the receiver escape — passing it to a function, storing it in an array — repaired it, which is what made the bug look like it depended on unrelated earlier statements. This is the READ half of the rule the write arms already apply: #9024 for `PropertySet`/`PutValueSet` and #9460 for `PropertyUpdate`, plus the sibling literal analysis in `escape_objects.rs`. Only the read arm was missing it. Reads of declared fields still take the no-heap scalar path, which is spec-correct because an own property shadows the chain and OrdinaryGet never reaches the prototype. Reads of undeclared keys now take the ordinary heap path. A fused method call is unaffected: its callee is handled in the `Expr::Call` arm and is no longer routed through `PropertyGet`, so `simple_scalar_method_summary` receivers stay scalar-replaced. --- changelog.d/10689-inherited-read-escape.md | 33 +++ .../src/collectors/escape_check.rs | 73 +++-- .../object_prototype_value_read_10689.rs | 280 ++++++++++++++++++ 3 files changed, 367 insertions(+), 19 deletions(-) create mode 100644 changelog.d/10689-inherited-read-escape.md create mode 100644 crates/perry/tests/object_prototype_value_read_10689.rs diff --git a/changelog.d/10689-inherited-read-escape.md b/changelog.d/10689-inherited-read-escape.md new file mode 100644 index 0000000000..fd7580b402 --- /dev/null +++ b/changelog.d/10689-inherited-read-escape.md @@ -0,0 +1,33 @@ +### Fixed + +- **`typeof o.toString` on a non-escaping object literal answered `undefined` (#10689).** + Reading an *inherited* member as a VALUE — `o.constructor`, `o.toString`, + `o.hasOwnProperty`, a user-added `Object.prototype` property, or a class's own + prototype METHOD read as a value — answered `undefined` whenever the receiver + was a scalar-replacement candidate, while *calling* the same member + (`o.toString()`, `"" + o`, `` `${o}` ``) was correct.

The hand-written native jsonwebtoken binding (crates/perry-ext-jsonwebtoken, plus a second duplicate implementation in crates/perry-stdlib/src/jsonwebtoken.rs exporting the same js_jwt_* symbols per #10678) has a live security defect: verify() returns null instead of throwing on every forgery case (tampered payload, wrong secret, alg:none, garbage token, tampered signature, expired token), so `try { jwt.verify(...) } catch { reject() }` never rejects a forgery. sign(..., { expiresIn: "1h" }) also silently drops the expiry (string coerces to NaN, and the runtime only writes `exp` when > 0.0). Removes both copies plus the dedicated codegen lowering path (lower_call/native/jsonwebtoken.rs's lower_jsonwebtoken_sign/_verify and its native_runtime_branch.rs dispatch), the decode-only NativeModSig row in native_table/utils_crypto.rs, the js_jwt_* FFI declarations in runtime_decls/stdlib_ffi/third_party.rs, the well_known_bindings.toml entry, the NATIVE_MODULES/manifest rows, the bundled-jsonwebtoken stdlib feature (re-wiring dep:rsa/dep:spki directly onto perry-stdlib's `crypto` feature, since webcrypto/key_object.rs and keys.rs need them independently of jsonwebtoken), and the Android stub exports. The real `jsonwebtoken` crates.io dependency stays — it is unrelated Rust tooling used by perry's own Apple code-signing (commands/run/resign.rs, commands/setup/common_apple.rs).

Updated workspace-architecture.json (workspace_members 83->82, externalize 33->32) and scripts/string_payload_access_baseline.txt (perry-stdlib inline-offset sites 40->39, from the deleted stdlib file). --- Cargo.lock | 12 - Cargo.toml | 2 - crates/perry-api-manifest/src/entries.rs | 1 - .../perry-api-manifest/src/entries/part_1.rs | 65 -- .../src/lower_call/native/jsonwebtoken.rs | 290 ------ .../src/lower_call/native/mod.rs | 4 - .../native/native_runtime_branch.rs | 7 - .../lower_call/native_table/utils_crypto.rs | 18 - .../runtime_decls/stdlib_ffi/third_party.rs | 21 - crates/perry-ext-jsonwebtoken/Cargo.toml | 22 - crates/perry-ext-jsonwebtoken/src/lib.rs | 399 -------- crates/perry-stdlib/Cargo.toml | 4 +- crates/perry-stdlib/src/jsonwebtoken.rs | 904 ------------------ crates/perry-stdlib/src/lib.rs | 5 - crates/perry-ui-android/src/stdlib_stubs.rs | 20 - crates/perry/src/commands/stdlib_features.rs | 1 - crates/perry/well_known_bindings.toml | 12 - docs/api/perry.d.ts | 11 +- docs/src/api/reference.md | 11 +- docs/src/native-libraries/governance.md | 1 - scripts/string_payload_access_baseline.txt | 2 +- scripts/unrooted_local_shape_baseline.json | 1 - workspace-architecture.json | 9 +- 23 files changed, 6 insertions(+), 1816 deletions(-) delete mode 100644 crates/perry-codegen/src/lower_call/native/jsonwebtoken.rs delete mode 100644 crates/perry-ext-jsonwebtoken/Cargo.toml delete mode 100644 crates/perry-ext-jsonwebtoken/src/lib.rs delete mode 100644 crates/perry-stdlib/src/jsonwebtoken.rs diff --git a/Cargo.lock b/Cargo.lock index 7693bb21b9..8d196773a2 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -6026,17 +6026,6 @@ dependencies = [ "tokio", ] -[[package]] -name = "perry-ext-jsonwebtoken" -version = "0.5.1597" -dependencies = [ - "base64 0.22.1", - "jsonwebtoken", - "perry-ffi", - "serde", - "serde_json", -] - [[package]] name = "perry-ext-lru-cache" version = "0.5.1597" @@ -6420,7 +6409,6 @@ dependencies = [ "hyper", "hyper-util", "image", - "jsonwebtoken", "lazy_static", "lettre", "libc", diff --git a/Cargo.toml b/Cargo.toml index baed25af0c..081a017221 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -16,7 +16,6 @@ members = [ "crates/perry-ext-uuid", "crates/perry-ext-bcrypt", "crates/perry-ext-argon2", - "crates/perry-ext-jsonwebtoken", "crates/perry-ext-validator", "crates/perry-validation", "crates/perry-perex", @@ -482,7 +481,6 @@ perry-ext-nanoid = { path = "crates/perry-ext-nanoid" } perry-ext-uuid = { path = "crates/perry-ext-uuid" } perry-ext-bcrypt = { path = "crates/perry-ext-bcrypt" } perry-ext-argon2 = { path = "crates/perry-ext-argon2" } -perry-ext-jsonwebtoken = { path = "crates/perry-ext-jsonwebtoken" } perry-ext-validator = { path = "crates/perry-ext-validator" } perry-validation = { path = "crates/perry-validation" } perry-perex = { path = "crates/perry-perex" } diff --git a/crates/perry-api-manifest/src/entries.rs b/crates/perry-api-manifest/src/entries.rs index 0e1415b629..de7f6a8bec 100644 --- a/crates/perry-api-manifest/src/entries.rs +++ b/crates/perry-api-manifest/src/entries.rs @@ -47,7 +47,6 @@ pub const NATIVE_MODULES: &[&str] = &[ "crypto", // (Node builtin) hashing, HMAC, cipher, sign/verify, WebCrypto "dotenv", // .env file loader "dotenv/config", // dotenv's auto-load-on-import subpath - "jsonwebtoken", // JWT sign/verify "nanoid", // compact URL-safe ID generation "validator", // string validators/sanitizers "ethers", // Ethereum library (utils/wallet/ABI) diff --git a/crates/perry-api-manifest/src/entries/part_1.rs b/crates/perry-api-manifest/src/entries/part_1.rs index aa51556739..5af3539565 100644 --- a/crates/perry-api-manifest/src/entries/part_1.rs +++ b/crates/perry-api-manifest/src/entries/part_1.rs @@ -1166,71 +1166,6 @@ pub(crate) const API_MANIFEST_PART_1: &[ApiEntry] = &[ }], TypeSpec::Number, ), - method_sig( - "jsonwebtoken", - "sign", - false, - None, - &[ - ParamSpec::Named { - name: "payload", - ty: TypeSpec::Any, - optional: false, - }, - ParamSpec::Named { - name: "secret", - ty: TypeSpec::String, - optional: false, - }, - ParamSpec::Named { - name: "options", - ty: TypeSpec::Any, - optional: true, - }, - // #915: FFI's 4th arg is `kid_ptr: *const StringHeader` — the - // dispatch table padding zeroes it when the user doesn't pass - // it.

implicit-ctor args to a native base super() reached via require() A CommonJS-wrapped module runs its whole body inside the wrap's IIFE, so every top-level const -- including const { AsyncResource } = require("node:async_hooks") -- is a genuine local. Class-heritage resolution's locally_shadowed check (perry-hir/src/lower_decl/class_decl.rs) could not distinguish that from a real user shadow (const EventEmitter = MyOwnClass), so it always fell back to the dynamic extends_expr / js_fetch_or_value_super dispatch and lost the native base's install + argument forwarding. For bases whose runtime value is a genuine ES class (AsyncResource, AsyncLocalStorage), that dynamic dispatch calls the value without new and throws. For bases backed by an old-style function (EventEmitter, node:stream classes) it happens to complete, but through a far more expensive indirect path. Record require()-destructured bindings' provenance (local name -> export key) unconditionally in var_decl_sources.rs, regardless of the #8342 CJS-wrapper gate that skips the full native-module-alias registration for the same binding, and consult it from both class-heritage arms (declaration and expression) so a local is only treated as shadowing when it did NOT come from a require() of the real native module. crates/perry-hir/src/lower/context.rs was exactly at the 2000-line file cap; the new field's init line tipped it over.

The accessors disagreed on the same string. 200,000 indexed reads of `typescript@5.9.3`'s `lib.dom.d.ts` (1,874,815 chars, 45 of them non-ASCII): charCodeAt 2 ms codePointAt 13,049 ms Scaling over a string with a single `é`, time quadrupling per doubling: n=5,000 8 ms n=20,000 128 ms n=10,000 32 ms n=40,000 518 ms `codePointAt` is defined on code units, so no bespoke decoding is needed: route it through `utf16_unit_at` and apply the spec algorithm — read the unit, and only when it is a leading surrogate with a trailing surrogate after it combine the pair. That keeps the bounded WTF-8 stepping #6085 requires, so a payload ending in a truncated multi-byte lead still decodes from what is present instead of over-reading; the existing guard-page test `code_point_at_does_not_read_past_payload` covers that and still passes. After, same hardware, against Node v26.5.1: 200k reads, non-ASCII 13,049 ms -> 2 ms (node 1 ms) n=40,000 scan 518 ms -> 1 ms (node 0 ms) tsc --noEmit demo.ts 658.31 s -> 85.04 s user (node 0.80 s) The tsc figure is the motivating case: `sample` attributed ~85% of that run to `js_string_code_point_at` and ~12% to `copy_utf16_range` underneath it, because TypeScript's scanner calls `codePointAt` per character and `lib.dom.d.ts` — the largest file it loads — carries those 45 non-ASCII characters. 7.7x on the real workload, and the remaining gap is no longer string indexing. Values are unchanged: `"a\u{1F600}b"` still yields 97, 128512, 56832, 98 at indices 0-3 (astral code point at the pair start, bare trailing surrogate on the low half), `"ab".codePointAt(5)` is still undefined, all byte-identical to Node. Tests: two added next to the index they exercise — one walks every index of a long non-ASCII string containing a surrogate pair and compares against an independent UTF-16 expansion, one asserts forward and backward traversal agree so the cursor cannot serve a stale answer on a backward seek. --- changelog.d/10656-codepointat-linear.md | 5 ++ crates/perry-runtime/src/string/char_ops.rs | 59 +++++++++----- .../src/string/char_ops/utf16_index/tests.rs | 77 +++++++++++++++++++ 3 files changed, 121 insertions(+), 20 deletions(-) create mode 100644 changelog.d/10656-codepointat-linear.md diff --git a/changelog.d/10656-codepointat-linear.md b/changelog.d/10656-codepointat-linear.md new file mode 100644 index 0000000000..31a8d597fa --- /dev/null +++ b/changelog.d/10656-codepointat-linear.md @@ -0,0 +1,5 @@ +`String.prototype.codePointAt` is no longer O(n) per call on strings containing +non-ASCII characters.

charset=UTF-8 Content-Transfer-Encoding: 8bit `copy_utf16_range` resolved its start boundary with `advance(bytes, Boundary::default(), start)` — a walk from byte 0 on every call. Slicing a non-ASCII string at increasing offsets, which is what every tokenizer does, was therefore O(n^2): n=20,000 33 ms n=80,000 404 ms n=40,000 102 ms n=160,000 1,662 ms ASCII controls are flat at every size, so this is the fast-path loss rather than the copy itself. This is the same pathology as #10055: #10067 moved `charCodeAt` and bracket indexing onto the lazy index, #10656 moved `codePointAt`, and this was the accessor still left on the walk. `Index::seek` is factored out of `unit_at` so `unit_at` and the new `boundary_at` share one implementation and one cursor rather than drifting apart — which is how the other two were missed. `boundary_at` returns `None` for short payloads and `start == 0`, where the caller's own walk is already cheap and a four-entry cache should not be disturbed, so those keep their existing behaviour exactly. After, against Node v26.5.1: substring scan, n=160,000 1,662 ms -> 1 ms (node 0 ms) tsc --noEmit demo.ts 85.04 s -> 7.76 s user (node 0.80 s) 11x on real tsc, and 85x cumulative against the 658.31 s this started at. `sample` had attributed ~97% of the remaining run to `copy_utf16_range` (50,627 of ~51,700 leaf samples; next symbol 162), because TypeScript's scanner extracts every token with `substring` and `lib.dom.d.ts` carries 45 non-ASCII characters in 1.87 MB. Correctness is unchanged, including the cases a wrong boundary would corrupt rather than merely slow: hashing every substring of a string containing astral characters (all i,j pairs, including ones that split a surrogate pair) gives 1234090636 on both Perry and Node, split-pair slices still yield the lone halves "\ud83d" / "\ude00", and a random-access-order slice hash matches. Tests: `boundary_at_matches_a_walk_from_zero` compares the indexed lookup against `advance` from zero at every index of a string containing both a two-byte scalar and a surrogate pair; `boundary_at_is_order_independent` asserts forward and backward traversal agree so the cursor cannot serve a stale boundary after a backward seek. 158 `string::` tests pass. --- changelog.d/10685-slice-linear.md | 5 ++ crates/perry-runtime/src/string/char_ops.rs | 8 +++ .../src/string/char_ops/utf16_index.rs | 61 ++++++++++++++++++- .../src/string/char_ops/utf16_index/tests.rs | 47 ++++++++++++++ .../perry-runtime/src/string/slice_range.rs | 11 +++- 5 files changed, 129 insertions(+), 3 deletions(-) create mode 100644 changelog.d/10685-slice-linear.md diff --git a/changelog.d/10685-slice-linear.md b/changelog.d/10685-slice-linear.md new file mode 100644 index 0000000000..207f47a863 --- /dev/null +++ b/changelog.d/10685-slice-linear.md @@ -0,0 +1,5 @@ +`String.prototype.substring` / `slice` / `substr` no longer walk from byte 0 to +resolve their start offset on strings containing non-ASCII characters.

A `GC_TYPE_ARRAY` header can never be a registered buffer or typed array — every registration carries its own GC object type — and `array/header.rs`'s `receiver_may_be_registered_exotic` exists to say so in one already-warm header byte read plus an integer compare. Thirteen call sites in `array/iter_methods.rs` already used that gate. None in `array/indexing.rs` did. Measured with the runtime's own `PERRY_BUFFER_DIAG` on `tsc --noEmit demo.ts` (a two-line input): before: probes=79,691,777 admits=26,198,956 true_positives=90 after: probes=39,845,889 admits=21,646,032 true_positives=90 79.7M probes to answer a question about a set that never holds more than 9 buffers, and is answered yes 90 times. Honest perf note: this is not measurable on tsc wall-clock. `is_registered_buffer_slow` was 2.8% of leaf samples, so halving its calls predicts ~1.4%; five interleaved rounds give a median of -1.2% with overlapping ranges (A 6.85-8.02s, B 6.76-7.86s), i.e. below the noise floor at that sample size. The change earns its place on correctness and consistency — it removes provably-wasted work and makes the indexing path match the gate every iteration helper already uses — not on a demonstrated speedup. Buffer-heavy workloads should benefit more; tsc is not one. Gating the four remaining `||`-shaped probe sites in the same file changed the probe count by zero, so the other ~39.8M originate outside `array/indexing.rs` and are still unattributed. #10694 also records that the diagnostic sizes a 1024-bit/3-hash Bloom at 0.0% false-positive on this workload, which would make each surviving probe ~free regardless of caller.

A program interleaving indexed access across five or more non-ASCII strings evicted the entry it was about to need on every access and rebuilt it from scratch, forever. It was a step function, not a gradual decay: K interleaved before after 1 67 ns 67 ns 4 50 ns 67 ns 5 81,525 ns 67 ns 8 80,972 ns 67 ns 12 81,228 ns 67 ns 1,217x at K>=5, and flat everywhere. An ASCII control stays at 25-39 ns in both, which isolates the cause to the index rather than to string count. Capacity was the defect, so there is no capacity: the cache becomes an owner-keyed map and entries live until their string dies. The lifetime machinery already existed — `prune_dead_utf16_indexes` is driven by the collector — so this reuses it rather than inventing ownership. Raising `CACHE_ENTRIES` would only move the wall to K+1. I first tried changing the table's *shape* instead (sparse run-boundary syncs with affine spans, prototyped at 108x less index memory); it made this cliff 23% WORSE, 81,525 -> 100,287 ns, because K>=5 is a pure *rebuilding* workload and a run table builds more slowly than it queries. That experiment is written up on #10688 and is what established that the fix had to be "stop rebuilding". `scan_utf16_index_roots_mut` now drains, lets the visitor rewrite the owner identities the map is keyed by, and reinserts — the keys are exactly what the collector relocates, so they must be rehashed rather than mutated in place. Memory: peak RSS on `tsc --noEmit demo.ts` is 606.7 MB against 613.4 MB for the same binary without this change, i.e. slightly lower rather than higher. Entries are unbounded between collections by construction, which is a real change in character even though it does not cost anything measurable here. Tests: 158 `string::` tests pass single-threaded. The former `cache_eviction_is_bounded_and_short_strings_do_not_evict_sources` asserted `len() <= CACHE_ENTRIES`, which is now false by design, so it is replaced by `indexes_survive_any_number_of_interleaved_strings` — 16 strings, four times the old capacity, asserting every index survives, still answers correctly on a second pass, and is reclaimed by the prune hook. It keeps that test's other, capacity-independent invariant: a one-character string from `char_at` must not disturb its source's index. `gc::tests::copy_slot_decode::sabotaged_remembering_arm_is_refused_by_the_coverage_cross_check` fails identically with and without this change (same panic site, `copy_slot_decode.rs:135`), verified by running it alone against both trees; it is pre-existing and unrelated. --- changelog.d/10688-per-string-index.md | 6 + .../src/string/char_ops/utf16_index.rs | 108 +++++++++--------- .../src/string/char_ops/utf16_index/tests.rs | 38 +++++- 3 files changed, 96 insertions(+), 56 deletions(-) create mode 100644 changelog.d/10688-per-string-index.md diff --git a/changelog.d/10688-per-string-index.md b/changelog.d/10688-per-string-index.md new file mode 100644 index 0000000000..1c45c5380a --- /dev/null +++ b/changelog.d/10688-per-string-index.md @@ -0,0 +1,6 @@ +The UTF-16 index no longer lives in a fixed four-slot cache that evicted +round-robin.

That poll costs about 436 instructions -- it evaluates the whole budgeted trigger ladder, which has no cheap "nothing is due" precheck -- and on this loop it enables no collection at all: matches are written into a native span buffer, so the loop creates nothing traced. Measured rather than argued. Nulling this poll entirely moves peak RSS on an allocating replace at n=1,000,000 by +0.0% median over nine interleaved rounds, 4 of 9 rounds in each direction. The same change applied to `Pieces::finish`, which does produce garbage, moved that figure +13.2% with 8 of 9 rounds against -- so this is a controlled contrast between an exposed and an unexposed site, not an assumption that polls are cheap to drop.

Answers are identical to Node 26.5.1 and to the previous build on every probe. Worst-case work between executed polls does not grow. Every search this loop performs goes through `find_near`, which either polls unconditionally (the owned path and any lent fallback) or ticks `PRE_SEARCH_POLL_TICK` and polls on one search in 64 (#10494). That tick advances once per search, which is once per iteration of this loop, so the two strides run in parallel on the same unit rather than composing: the bound stays 64 searches either way. The stride value matches `PRE_SEARCH_POLL_STRIDE` because they must count the same unit, not because 64 is derived. It is a chosen margin in #10494 -- the evidence there argues for removing the poll, not for any particular stride -- and nothing here depends on it being the right number, only on not exceeding the value already bounding this path. --- .../src/regex/perex_replace_direct.rs | 32 ++++++++++++++++++- 1 file changed, 31 insertions(+), 1 deletion(-) diff --git a/crates/perry-runtime/src/regex/perex_replace_direct.rs b/crates/perry-runtime/src/regex/perex_replace_direct.rs index dd715048ff..4dafcee987 100644 --- a/crates/perry-runtime/src/regex/perex_replace_direct.rs +++ b/crates/perry-runtime/src/regex/perex_replace_direct.rs @@ -74,6 +74,16 @@ pub(super) fn admissible(receiver: &RuntimeHandle<'_>, reuse: &Reuse<'_, '_>) -> && reuse.name_count(re) == Some(0) } +/// One collection-loop round in this many runs the GC safepoint poll. +/// +/// The value matches `PRE_SEARCH_POLL_STRIDE`, and deliberately so: both count +/// one search, so they are parallel on the same unit rather than nested.

The loop that collects the matches asked the collector whether it was due to run once per match, which costs about 436 instructions and could never do anything there — that loop writes its matches into a native buffer and creates nothing the collector can free. It now asks once per 64 matches, which is the same bound each search was already keeping. Peak memory is unchanged, measured over nine interleaved rounds of a replace at n=1,000,000 (#10165).

perry-codegen suites `e2e-scoped` has been red on every PR since merge train 218 (v0.5.1596), failing at "Compute e2e suite scope" in ~16s: ci_e2e_scope: these crates/perry-codegen/tests/*.rs suites are in neither SOURCE_SUITE_MAP nor SUITE_EXCLUSIONS: error_subclass_field_init, typed_collection_receiver_guard Both suites arrived in 6925754a7d (#10443/#10446, train 218) and nobody classified them, which is exactly the condition #7708 added this assertion for. The failure is content-independent, so it reddens PRs that cannot possibly have caused it -- #10721 (a Python script) and #10722 (a .ts fixture) both carry it.

Root cause: BUFFER_PROTOTYPE_METHODS (which populates Buffer.prototype's own enumerable properties) was generated from the SAME name table buffer_dispatch::is_buffer_method_name uses to decide whether a property read on a Buffer INSTANCE should synthesize a bound-method closure - deliberately broad, for duck-typed inherited-method reads - conflating that broad instance-read predicate with the narrow set of names that should be Buffer.prototype's own keys. Decoupled the two: curated BUFFER_PROTOTYPE_METHODS down to Node's real 96-name own-property surface (removing the 36 bogus entries, adding the 14 internal Slice/Write methods with real dispatch behavior, and adding offset/parent as accessor descriptors), while leaving is_buffer_method_name's broader instance-read predicate untouched. Also fixed a dormant gap the new ucs2Write method depends on: js_buffer_write_len's encoding match never handled tag 6 (utf16le/ ucs2), silently writing raw UTF-8 bytes instead - a pre-existing defect in buf.write(str, offset, 'utf16le') too. --- crates/perry-runtime/src/buffer/copy_write.rs | 6 + crates/perry-runtime/src/buffer/from.rs | 6 +- .../src/object/buffer_dispatch.rs | 73 ++++++++ .../object/native_module/callable_exports.rs | 172 +++++++++++++----- .../test_gap_10426_buffer_prototype_shape.ts | 163 +++++++++++++++++ 5 files changed, 376 insertions(+), 44 deletions(-) create mode 100644 test-files/test_gap_10426_buffer_prototype_shape.ts diff --git a/crates/perry-runtime/src/buffer/copy_write.rs b/crates/perry-runtime/src/buffer/copy_write.rs index 4fbed786f1..20315d64b8 100644 --- a/crates/perry-runtime/src/buffer/copy_write.rs +++ b/crates/perry-runtime/src/buffer/copy_write.rs @@ -105,6 +105,12 @@ pub extern "C" fn js_buffer_write_len( let bytes_to_write = match encoding { 1 => decode_hex(str_bytes), 2 | 3 => decode_base64(str_bytes), + // #10426: encoding tag 6 (utf16le/ucs2) fell through to the + // default (raw UTF-8 bytes) arm — dormant in the pre-existing + // `buf.write(str, offset, 'utf16le')` path and would have made + // the new `ucs2Write` method equally wrong. `from::utf16le_string_bytes` + // is the same UTF-16LE encoder `Buffer.from(str, 'utf16le')` uses. + 6 => super::from::utf16le_string_bytes(str_bytes), _ => str_bytes.to_vec(), }; diff --git a/crates/perry-runtime/src/buffer/from.rs b/crates/perry-runtime/src/buffer/from.rs index 16ed61c8dd..50725ce64d 100644 --- a/crates/perry-runtime/src/buffer/from.rs +++ b/crates/perry-runtime/src/buffer/from.rs @@ -110,7 +110,11 @@ fn latin1_string_bytes(str_bytes: &[u8]) -> Vec { out } -fn utf16le_string_bytes(str_bytes: &[u8]) -> Vec { +/// #10426: made `pub(crate)` so `copy_write.rs`'s `js_buffer_write_len` +/// can reuse it for the new `ucs2Write` method (and to close the same gap +/// in the pre-existing generic `buf.write(str, offset, 'utf16le')` path, +/// which silently wrote raw UTF-8 bytes instead of UTF-16LE before this). +pub(crate) fn utf16le_string_bytes(str_bytes: &[u8]) -> Vec { let decoded = String::from_utf8_lossy(str_bytes); let mut out = Vec::with_capacity(decoded.len() * 2); for unit in decoded.encode_utf16() { diff --git a/crates/perry-runtime/src/object/buffer_dispatch.rs b/crates/perry-runtime/src/object/buffer_dispatch.rs index ae1fcc2a72..0e5a90280c 100644 --- a/crates/perry-runtime/src/object/buffer_dispatch.rs +++ b/crates/perry-runtime/src/object/buffer_dispatch.rs @@ -243,8 +243,43 @@ buffer_method_names!( "getBigUint64", "setBigInt64", "setBigUint64", + // #10426: Node's internal fixed-encoding slice/write pair, present as + // real own methods on `Buffer.prototype` (`buf.write(str, off, enc)` / + // `buf.toString(enc, start, end)` dispatch through these internally in + // Node; Perry exposes the same names so duck-typed reads and direct + // calls both work, matching `Object.getOwnPropertyNames(Buffer.prototype)`). + "asciiSlice", + "asciiWrite", + "base64Slice", + "base64Write", + "base64urlSlice", + "base64urlWrite", + "hexSlice", + "hexWrite", + "latin1Slice", + "latin1Write", + "ucs2Slice", + "ucs2Write", + "utf8Slice", + "utf8Write", ); +/// Fixed encoding tag for one of Node's internal `Buffer.prototype` +/// `Slice`/`Write` methods (#10426).

A thread_local! address resolution is readnone from LLVM's point of view, so once inlined, the optimizer hoisted the proxy registry's and the transient-handle root stack's TLS lookups out of their guards (is_proxy_id_band, a "size"-key check) and ran them unconditionally on every js_object_get_field_by_name call, Proxy or not.

That check costs about 436 instructions: it evaluates the whole budgeted trigger ladder, which has no cheap "nothing is due" precheck. Both passes now poll once per POLL_UNITS units read. Unlike the collection loop in `perex_replace_direct`, these passes are downstream of the replacement's traced pieces and its replacer's strings, so they do produce garbage and polling far less often costs peak RSS. POLL_UNITS is therefore a measured trade, not a bound inherited from elsewhere: at `api::QUANTUM` (4096) the instruction win is the same but peak RSS is +13.2% median on an allocating replace at n=1,000,000, over the accepted +10% budget.

Real npm validator matches Node for all 50 checks. Per #10678 (duplicate extern "C" exports across perry-ext-*/perry-stdlib pairs), this binding existed twice, plus a shared helper crate used only by the two duplicates: - crates/perry-ext-validator/ — the governance-tracked binding crate. - crates/perry-stdlib/src/validator.rs (425 lines) — a second, independent implementation behind the `bundled-validator` feature (default-on via the `validation` umbrella, itself in `full`), exporting the same js_validator_* symbols. - crates/perry-validation/ — "Shared borrowed string validators for Perry's bundled and extension bindings" (its own doc comment): a small email/URL/ UUID grammar helper consumed exclusively by the two crates above. With both gone, nothing references it, so it goes too. Removed all three crates, the 5-entry NativeModSig dispatch block in native_table/utils_crypto.rs (isEmail/isURL/isUUID/isJSON/isEmpty — the only validator methods with a dedicated codegen row; the rest were reachable only through the deleted FFI crates), the 16 js_validator_* FFI declarations in runtime_decls/stdlib_ffi/streams_events.rs, the well_known_bindings.toml entry, the NATIVE_MODULES/manifest rows, the validation/bundled-validator stdlib features (and "validation" from perry-stdlib's `full` feature list), and the 16 Android stub exports. Regenerated docs/api/perry.d.ts, docs/src/api/reference.md, and docs/src/native-libraries/governance.md. Updated workspace-architecture.json (workspace_members 83->81, externalize 33->32, keep 45->44 — two crates removed, perry-ext-validator was "externalize" and perry-validation was "keep"/runtime-core). --- Cargo.lock | 34 -- Cargo.toml | 4 -

From ab82a224cf9ae063a39adc341e0c435f13166f79 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ralph=20K=C3=BCpper?= Date: Fri, 18 Sep 2026 15:05:57 +0000 Subject: [PATCH 101/126] fix(runtime): route AsyncLocalStorage super() through any bound-export heritage shape class X extends AsyncLocalStorage threw "Class constructor AsyncLocalStorage cannot be invoked without 'new'" at super() for every heritage shape except a bare import { AsyncLocalStorage } from "node:async_hooks" binding -- the same defect #10621 fixed for AsyncResource (#10453). A local alias, a namespace member, a default import, and a CJS destructured require() all reach the identical bound native export value the bare import does, but only that shape is recognized statically at HIR-lowering time (crates/perry-hir/src/lower_decl/class_decl.rs), which routes to perry-stdlib's js_async_local_storage_subclass_init via a codegen-declared extern symbol. Every other shape fell through js_fetch_or_value_super to a plain CALL of the bound export. Unlike AsyncResource, whose implementation lives entirely in perry-runtime, AsyncLocalStorage's subclass-init helper lives in perry-stdlib (it needs the stdlib Handle registry), and perry-runtime cannot depend on perry-stdlib. Route through a registration hook perry-stdlib installs at startup (JS_NATIVE_ASYNC_LOCAL_STORAGE_SUBCLASS_INIT), matching the existing JS_NATIVE_ASYNC_HOOKS_CONSTRUCT / JS_NATIVE_EVENTS_CONSTRUCT pattern already used for this exact kind of cross-crate reach. Adds test_gap_10625_asynclocalstorage_heritage.ts covering the canonical import (control), local alias, namespace member, default import, and two CJS require() shapes, asserting a real run()/getStore() round-trip through the subclass -- not just that construction doesn't throw. --- crates/perry-runtime/src/lib.rs | 12 +-- .../src/object/global_this/fetch_globals.rs | 31 +++++++ crates/perry-runtime/src/value/handle.rs | 11 +++ crates/perry-runtime/src/value/mod.rs | 33 ++++---- crates/perry-runtime/src/value/tags.rs | 16 ++++ .../perry-stdlib/src/common/dispatch/init.rs | 12 +++ ...0625_asynclocalstorage_heritage_helper.cjs | 22 +++++ ...st_gap_10625_asynclocalstorage_heritage.ts | 83 +++++++++++++++++++ 8 files changed, 199 insertions(+), 21 deletions(-) create mode 100644 test-files/gap_10625_asynclocalstorage_heritage_helper.cjs create mode 100644 test-files/test_gap_10625_asynclocalstorage_heritage.ts diff --git a/crates/perry-runtime/src/lib.rs b/crates/perry-runtime/src/lib.rs index ceec019f32..2898e95751 100644 --- a/crates/perry-runtime/src/lib.rs +++ b/crates/perry-runtime/src/lib.rs @@ -361,12 +361,12 @@ pub use value::{ pub use value::{ js_set_handle_array_get, js_set_handle_array_length, js_set_handle_call_method, js_set_handle_object_get_property, js_set_handle_to_string, js_set_handle_typeof, - js_set_native_async_hooks_construct, js_set_native_bun_tcp_dispatch, - js_set_native_crypto_dispatch, js_set_native_domain_dispatch, js_set_native_events_construct, - js_set_native_events_dispatch, js_set_native_http_dispatch, js_set_native_module_js_loader, - js_set_native_net_dispatch, js_set_native_querystring_dispatch, js_set_native_sqlite_dispatch, - js_set_native_tls_dispatch, js_set_native_webcrypto_dispatch, js_set_native_zlib_dispatch, - js_set_new_from_handle_v8, + js_set_native_async_hooks_construct, js_set_native_async_local_storage_subclass_init, + js_set_native_bun_tcp_dispatch, js_set_native_crypto_dispatch, js_set_native_domain_dispatch, + js_set_native_events_construct, js_set_native_events_dispatch, js_set_native_http_dispatch, + js_set_native_module_js_loader, js_set_native_net_dispatch, js_set_native_querystring_dispatch, + js_set_native_sqlite_dispatch, js_set_native_tls_dispatch, js_set_native_webcrypto_dispatch, + js_set_native_zlib_dispatch, js_set_new_from_handle_v8, }; // Extension pump registration — allows extensions to register pump functions diff --git a/crates/perry-runtime/src/object/global_this/fetch_globals.rs b/crates/perry-runtime/src/object/global_this/fetch_globals.rs index 2160572c59..13cbe05c23 100644 --- a/crates/perry-runtime/src/object/global_this/fetch_globals.rs +++ b/crates/perry-runtime/src/object/global_this/fetch_globals.rs @@ -724,6 +724,37 @@ pub unsafe extern "C" fn js_fetch_or_value_super( crate::async_hooks::js_async_resource_subclass_init(this_box, type_value, options); return undef; } + // #10625: `class X extends AsyncLocalStorage` reached indirectly (local + // alias, namespace member, CJS destructured `require()`) hits the same gap + // #10453/#10621 fixed for AsyncResource: only the canonical bare + // `import { AsyncLocalStorage } from "node:async_hooks"` binding is + // recognized statically at HIR-lowering time + // (`crates/perry-hir/src/lower_decl/class_decl.rs`), which routes to + // perry-stdlib's `js_async_local_storage_subclass_init` via a + // codegen-declared extern symbol + // (`crates/perry-codegen/src/expr/this_super_call.rs`).

That is an `external global`, so on arm64 reading it costs `adrp` + a GOT `ldr` + a dependent `ldrb` through it + a compare — four instructions and TWO dependent loads, in the gate block, before the guard has looked at the receiver at all. It cannot be hoisted: the runtime flips it mid-execution when a descriptor or accessor lands on a class prototype, so the load is `volatile` by necessity. The authority moves onto a value the guard already had to load. Each class gains `@perry_class_guard_shape_*`, seeded at module init with the same ShapeId as `@perry_class_shape_id_*` and registered with the runtime; `disable_class_field_inline_guard` now poisons every registered slot with `u32::MAX`. ShapeIds are allocated from `[0x8000_0000, 0xC000_0000)` and never reused, so a poisoned expectation can never match a live object — every guard misses and routes to the IC, which is exactly what the latch bought. The expectation is read volatile per access for the same freshness reason the latch was, and is still cheaper: one module-local `adrp`+`ldr`, no GOT hop. It is a SEPARATE global from the ShapeId on purpose. `js_object_alloc_class_inline_keys_stamped` stamps every new instance with the value read out of the ShapeId global (`lower_call/new_alloc.rs`), so poisoning that one would brand live objects with a bogus ShapeId instead of closing a fast path. Subclass arms move to the poisonable global too, or a subclass receiver would keep hitting the fast path after a flip. Imported-class stubs carry the expectation through `js_register_imported_class_shape_slot`, and a rewrite that lands after a disable re-poisons rather than resurrects. Measured, arm64, `-Os` + `llc -O2 -mcpu=apple-m1`: - one `o.a` on a typed receiver, executed fast path: 28 -> 23 instructions (-18%), one fewer dependent load; - 16 reads on one receiver, EXECUTED instructions per call (`/usr/bin/time -l`, best-of-5, differential over iteration count): 595.2 -> 563.0, -5.4%. The per-read marginal is -2 rather than -5 because LLVM already hoisted the latch's base register across accesses within a function. Unlike a clone-gated optimisation this fires wherever the guard does: the latch is gone from `$generic`, `$spec_b` AND the copy the inliner leaves in the caller, which is the code that actually executes. `js_class_field_get_ic`'s truthful ShapeId operand is now loaded in the cold miss arm instead of the function entry, since the fast path no longer reads it. The two updated ratchet tests pin both halves of the swap — three loads in the guard AND no latch — because "three loads" alone would also pass a lowering that kept the latch and added the expectation. --- crates/perry-codegen/src/codegen/mod.rs | 13 +++ .../perry-codegen/src/codegen/string_pool.rs | 13 +++ .../src/expr/class_field_inline_guard.rs | 22 +++-- .../src/expr/hit_path_access_tests.rs | 26 ++++- crates/perry-codegen/src/expr/property_get.rs | 17 +++- .../src/expr/property_get/helpers.rs | 2 +- crates/perry-codegen/src/expr/property_set.rs | 2 +- .../expr/property_set/sloppy_class_field.rs | 8 +- .../src/lower_call/method_override.rs | 2 +- .../src/lower_call/typed_shape_bake_tests.rs | 17 +++- .../src/runtime_decls/strings.rs | 3 +- crates/perry-codegen/src/typed_shape.rs | 17 ++++ .../src/gc/layout/typed_shape.rs | 66 +++++++++++++ .../src/object/class_guard_shape.rs | 95 +++++++++++++++++++ .../src/object/descriptor_state.rs | 13 +++ crates/perry-runtime/src/object/mod.rs | 4 + 16 files changed, 294 insertions(+), 26 deletions(-) create mode 100644 crates/perry-runtime/src/object/class_guard_shape.rs diff --git a/crates/perry-codegen/src/codegen/mod.rs b/crates/perry-codegen/src/codegen/mod.rs index fd80687d6d..ea3258c6f7 100644 --- a/crates/perry-codegen/src/codegen/mod.rs +++ b/crates/perry-codegen/src/codegen/mod.rs @@ -1198,6 +1198,14 @@ pub fn compile_module(hir: &HirModule, opts: CompileOptions) -> Result> I32, "0", ); + // The poisonable twin of the ShapeId global: same value, same linkage, + // but only ever COMPARED against — see + // `typed_shape::guard_shape_global_name_from_keys_global`. + llmod.add_global( + &crate::typed_shape::guard_shape_global_name_from_keys_global(&global_name), + I32, + "0", + ); // #8122: the inline-`new` header image, composed at module init // (`string_pool.rs`) for the classes `class_header_images` admits. llmod.add_internal_global( @@ -1391,6 +1399,11 @@ pub fn compile_module(hir: &HirModule, opts: CompileOptions) -> Result> I32, "0", ); + llmod.add_internal_global( + &crate::typed_shape::guard_shape_global_name_from_keys_global(&global_name), + I32, + "0", + ); // #8122: the inline-`new` header image, composed at module init // (`string_pool.rs`) for the classes `class_header_images` admits. llmod.add_internal_global( diff --git a/crates/perry-codegen/src/codegen/string_pool.rs b/crates/perry-codegen/src/codegen/string_pool.rs index d6570e7a6b..fa582cfd29 100644 --- a/crates/perry-codegen/src/codegen/string_pool.rs +++ b/crates/perry-codegen/src/codegen/string_pool.rs @@ -648,6 +648,18 @@ pub(super) fn emit_string_pool( ); blk.store(I32, &shape_id, &shape_global); + // Seed the guard expectation with the same ShapeId and hand the + // runtime its address, so `disable_class_field_inline_guard` can poison + // it.

Yet the compiler bakes the collector's header layout into emitted code twice over: the inline `new` path stores a packed `GcHeader` word as a COMPILE-TIME constant (#8122, pre-composed per class into `@perry_class_header_image_*`), and every class-field / element-shape / method-probe guard masks that word against a literal. So both sides carry their own `GC_TYPE_OBJECT`, `GC_FLAG_FORWARDED`, `OBJ_FLAG_HAS_DESCRIPTORS`, `GC_OBJ_TYPED_LAYOUT_INTACT` — 36 restatements across 10 files — held together by a code comment. Nothing enforced it. What looks like enforcement is const GC_FLAG_FORWARDED_I8: &str = "-128"; debug_assert_eq!(GC_FLAG_FORWARDED_I8, "-128"); which compares codegen's constant to a string literal: a tautology that never references the runtime, and is compiled out of `release` and `perry-dev` besides. Every codegen test naming these bits asserts codegen's own constant reaches the IR, so they pin codegen to itself and would all stay green. A flag renumbered in perry-runtime therefore compiled clean, passed every suite, and shipped a compiler whose inline allocator baked one bit layout while the collector read another — objects born with flags the GC misreads, which CLAUDE.md describes as surfacing cycles later as `TypeError: value is not a function`. `scripts/check_gc_header_constants.py` re-derives every restatement from the runtime constant it quotes, including the composites (`READ_FAST_PATH_BLOCKED` = ARRAY_DESCRIPTORS|HAS_DESCRIPTORS, the fused 32-bit masks `ELEM_HEADER_MASK` / `GC_OBJECT_METHOD_GUARD_MASK_I32`). A registered constant that stops existing FAILS, so a fix must delete its own entry; a new header-shaped `const` in a watched file must be registered or exempted with a reason, so the next one cannot arrive silently. `--self-test` proves it can fail; `--list` prints the whole duplicated surface, including the 6 constants deliberately out of scope. Build-free, so it joins `lint`, a required context. Writing the registry found 5 restatements a manual grep missed (they are declared inside function bodies, not at module scope): the array-literal allocator's three, and two copies of the method-probe fused mask. Two existing gates moved with it, both of which correctly caught this branch: `gc_store_site_inventory` wanted GC_STORE_AUDIT markers on the new raw slot writes (POINTER_FREE — a `u32` in the program's data segment, never a heap edge), and `shape_descriptor_census` pinned the precheck's old `expected_class_identity(..., expected_shape_id)` spelling. The census is updated to the new spelling AND strengthened: it now also requires the expectation to be read VOLATILE from the poisonable global, because a lowering that hoisted that load would reopen a fast path the runtime has closed and would still satisfy a shape-only assertion. Verified to fail when the `volatile` is dropped. This does not make the GC header bits movable — it makes moving them a red build instead of a silent miscompile. --- .github/workflows/test.yml | 18 + .../src/object/class_guard_shape.rs | 7 + scripts/check_gc_header_constants.py | 402 ++++++++++++++++++ scripts/shape_descriptor_census.py | 19 +- 4 files changed, 444 insertions(+), 2 deletions(-) create mode 100755 scripts/check_gc_header_constants.py diff --git a/.github/workflows/test.yml b/.github/workflows/test.yml index 3cd21240da..30bf439b9a 100644 --- a/.github/workflows/test.yml +++ b/.github/workflows/test.yml @@ -586,6 +586,24 @@ jobs: python3 scripts/check_node_version_consistency.py --self-test python3 scripts/check_node_version_consistency.py + # perry-codegen does NOT depend on perry-runtime, yet it bakes the + # collector's header layout into emitted code: the inline `new` path + # stores a packed GcHeader word as a compile-time constant (#8122) and + # every class-field / element-shape guard masks that word against a + # literal.

Each class +gains a `@perry_class_guard_shape_*` expectation, seeded at module init with +the class ShapeId and registered with the runtime; +`disable_class_field_inline_guard` poisons every registered slot with +`u32::MAX`. ShapeIds are allocated from `[0x8000_0000, 0xC000_0000)` and never +reused, so a poisoned expectation can never match a live object — every guard +misses and routes to the IC, exactly what the latch bought. + +It is deliberately a SEPARATE global from `@perry_class_shape_id_*`: that one is +stamped into every new instance by `js_object_alloc_class_inline_keys_stamped`, +so poisoning it would brand live objects with a bogus ShapeId rather than close +a fast path.

The per-read marginal is −2 rather +than −5 because LLVM already hoisted the latch's GOT base register across +accesses within a function. The latch is gone from `$generic`, `$spec_b` and +the copy the inliner leaves in the caller — the last of which is the code that +actually executes. + +### The compiler's copy of the GC header layout is now gated + +`perry-codegen` does not depend on `perry-runtime`, yet it bakes the collector's +header layout into emitted code: the inline `new` path stores a packed +`GcHeader` word as a compile-time constant, and every class-field / +element-shape / method-probe guard masks that word against a literal. Thirty-six +restatements across ten files, with the agreement held by a code comment — the +`debug_assert_eq!` that looked like enforcement compared codegen's constant to a +string literal, a tautology that never referenced the runtime and is compiled +out of `release` and `perry-dev` anyway. A flag renumbered in the runtime +compiled clean, passed every suite, and shipped a compiler whose allocator baked +one bit layout while the collector read another. + +`scripts/check_gc_header_constants.py` (in `lint`) re-derives every restatement +from the runtime constant it quotes, including composites and the fused 32-bit +masks. A registered constant that stops existing fails, so a fix deletes its own +entry, and a new header-shaped `const` in a watched file must be registered or +exempted with a reason. Writing the registry found five restatements a +module-scope grep misses, because they are declared inside function bodies. + +`shape_descriptor_census` gains a matching requirement: the class-field +precheck must read its expectation VOLATILE from the poisonable global, since a +lowering that hoisted that load would reopen a fast path the runtime has closed +and would still satisfy a shape-only assertion.

Perry's HIR lowers the namespace's exported `Agent` class as a static-field-set against a synthetic class entity that is not the same runtime value `export =` ends up exporting, so `require("agent-base").Agent` reads back `undefined` and the downstream `class HttpsProxyAgent extends agent_base_1.Agent` throws. `is_hybrid_cjs_emit_input` (resolve.rs) already falls back to a package's compiled JS emit for one other TS-source shape Perry can't correctly lower (#6586's ESM+CJS-epilogue hybrid). Extend it with a second, narrowly-scoped trigger: a top-level `namespace`/`module` block (excluding ambient `declare namespace`, which is type-only) combined with a top-level `export =` statement. Node can't run this non-erasable TS syntax directly either (`--experimental-strip-types` rejects `namespace`/`export =`), so a package built this way is never executed from its raw `.ts` source in practice — falling back to the compiled emit matches what Node actually runs, instead of attempting to implement namespace/function declaration-merging semantics in HIR.

blind spots in unrooted_local_shape.py #10713: `--no-raise-vs ` compared the merge base's recorded baseline with the checked-out one and never scanned the tree, so a branch that added findings without touching the baseline compared 561 against 561 and printed "no ceiling raised" while `--check` failed on the same worktree with `REGRESSION: 563 findings exceeds baseline 561`. It now scans the worktree and compares the measured total and per-file counts against the base's recorded ceilings, and prints the resolved base SHA with both totals. #10713, second hole: the dispatch was `if args.no_raise_vs:`, so the empty string an unset $BASE_SHA expands to was falsy, the mode was never entered, and the script fell through to the plain report and exited 0. Now `is not None`, with `resolve_ref` rejecting an empty ref the way raw_handle_debt.py's `git_show` rejects an unfetched one. #10715: `LET_BIND` was matched per line, so a binding rustfmt broke after the `=` -- a function of indentation depth and identifier length, not of anything about the code -- was never tracked. A `let` is now folded back into one statement first. Statements containing a brace stay line-oriented on purpose, so a closure body's own bindings do not go dark. The measured surface moves 558 -> 581 across 85 files (+34 newly visible, -11 false positives in ioredis.rs where a wrapped SHADOWING `let` failed to reset the identity). The baseline is deliberately NOT re-pinned: it still records 561, so both forms are red pending an audited schema migration. Each fix plants the defect it fixes in `--self-test`, verified by reverting each one in isolation. The old self-test passed on the day the live check was fooled, which was the point.

The deadline is a timeout, not a barrier: when it expired first the loop exited and the fixture printed `false` on two lines expected to read `true`, dropping `tick 1`/`tick 2` as well — a four-line divergence the harness reports as a `parity_fail`, i.e. as a miscompile. It is inside pr-gate's gap shards and absent from gap_snapshot.json, and it already held #10530 out of a train. The wait now has no deadline, so the printed text is a function of CronJob's behaviour alone: the ticks arrive, or PERRY_RUN_TIMEOUT kills the run and the harness classifies that as a crash/timeout rather than a parity mismatch. No fallback bound — any bound that prints or throws on expiry is the same defect with a longer fuse, and the old 10s was unreachable anyway because PERRY_RUN_TIMEOUT is also 10s. The never-started job now prints `neverTicks === 0` from a real counter instead of a hardcoded `true`, checked after the barrier. Output bytes unchanged.

The reporter's own isolated repro prints the expected text on all three trees that matter — current main (v0.5.1598), the main commit their branch forks from (8df83f8c12), and their actual tree (PR #10712 on top of #10699, head 463c4fa5) — and real commander 14.0.3 compiled from source via `perry.compilePackages` matches Node 26.5.1 byte for byte across the whole output surface the issue names: `--help`, `--version`, missing required argument, unknown option, unknown command and `program.error()`, under both the default output configuration and a `configureOutput()` override. 32 further shapes of the same indirection agree with Node too. So this adds the regression lock rather than a fix. The shape is worth gating: #10689 — an inherited property read folding to the constant `undefined` on a scalar-replaced object — landed one commit before this issue was filed and is the same family, silent in the same way. The fixture covers the reported form verbatim plus the method-shorthand, class-field, `configureOutput`-override, spread, nested-receiver, cross-object-writer and in-loop spellings. Two of the cases exist to keep the fixture from passing vacuously. One traces `before` / `typeof write` / `after` around the inner call, so "the outer body ran and the inner call evaporated" cannot read as a pass. The other omits the writer entirely and asserts a TypeError: that a missing callee is LOUD is the property that keeps this bug class from ever presenting as a plausible wrong answer. Every writer sinks to stdout because the parity harness merges stdout and stderr into one compared stream; the stream is incidental to the indirection.

net.Socket providers and unmask the ledger gate `scripts/native_result_ledger.py` is red on pristine `main`, blocking the path-filtered `Native Result Ledger / check` workflow on every PR that touches `native_table/**` or the ledger itself. Two independent defects, one hiding the other. 1. Stale row count (bookkeeping). #10658's `net.Socket` surface cluster landed in merge train 221 and grew `native_table/net_events.rs` from 53 to 58 typed rows. `EXPECTED_ROWS` stayed at 371, so the gate failed with `expected 371 classified rows, found 376`. 2. Four unclassified providers (the real defect). Those five new rows carry four runtime symbols that were never added to `native_result_ledger.tsv`, so the table declared a result class the provider inventory had no opinion about. An unclassified `result_kind` misrepresents to the GC what a native call returns. The count check runs FIRST and raises, so the classification-coverage check never executed: the stale constant was acting as a mask. Bumping the constant alone would have turned the gate green and shipped (2). Each of the four providers was read, not name-matched. All four return their `handle: i64` argument unchanged -- a `next_id_or_throw()` registry id and key into `statics::sockets()`, not a heap address -- which is exactly `NativeRetKind::HandleId` ("an integer registry id or provider sentinel"): js_ext_net_socket_on perry-ext-net/src/handle_exports.rs:65 js_net_socket_prepend_listener perry-ext-net/src/lifecycle.rs:1040 js_net_socket_prepend_once_listener perry-ext-net/src/lifecycle.rs:1060 js_net_socket_unpipe perry-ext-net/src/pipe.rs:325 `js_ext_net_socket_on` backs two rows (`on` and `addListener` share the symbol), hence five rows from four symbols.

The native binding is missing `parse`/`stringify` entirely (a `parse`/`stringify` roundtrip throws: `bytes` comes back `undefined`), and `NIL` reads as `undefined` (js_uuid_nil exists in the deleted source but was never wired into either NativeModSig dispatch table or the API manifest, so property access on the uuid module namespace fell through to undefined). v1/v3/v4/v5/validate/version were correct in both. Per #10678 (duplicate extern "C" exports across perry-ext-*/perry-stdlib pairs), this binding existed twice: crates/perry-ext-uuid/ (the governance-tracked binding crate) and crates/perry-stdlib/src/uuid.rs (a second, independent implementation behind the now-removed bundled-uuid feature). Both are deleted, along with the 7-entry NativeModSig dispatch block in native_table/utils_crypto.rs, the well_known_bindings.toml entry, the "uuid" NATIVE_MODULES entry and its 7 manifest rows, and the 6 Android stub exports. crypto/random.rs entanglement: crypto.randomUUID()/randomUUID({v7:true}) and nodemailer's message-id generation both call the `uuid` Cargo crate (uuid::Uuid::new_v4()/now_v7()) directly and unconditionally — neither site has a cfg(feature) gate. The `uuid` crate dependency in perry-stdlib/Cargo.toml was therefore never actually optional in practice even though it was declared `optional = true` behind the bundled-uuid npm-binding feature; removing that feature without also dropping `optional = true` would have broken the build the moment bundled-uuid stopped being enabled. Made `uuid` a required (non-optional) dependency and retargeted the `ids` feature umbrella to `["bundled-nanoid"]`. crypto.randomUUID()/randomUUID({v7:true}) and node:crypto's randomBytes are unaffected — verified below. Retargeted the one dts-shape regression test that used uuid.v4() as its zero-arg-module-function fixture (perry-api-manifest's dts_uuid_v4_has_no_args) to perry/gc.minor(), which is unrelated to any binding-removal churn. Built on perrymaster (--profile perry-dev). A real `npm install uuid` project (no perry.compilePackages entry) exercising v1/v4/v5/v3, validate/version, a parse/stringify roundtrip, and NIL, diffed against `node --experimental-strip-types` (Node 26.5.1): byte-for-byte identical, including the deterministic v5/v3 (name+namespace) values. Confirmed against a pristine origin/main (8df83f8c1) baseline build that the same program crashes there: `NIL: undefined`, `parse instanceof Uint8Array: false`, then `TypeError: Cannot read properties of undefined (reading 'length')` on the roundtrip — reproducing the reported bug exactly. crypto.randomUUID() and node:crypto's randomBytes/randomUUID were re-checked against the fix and still work (both call the `uuid` crate directly, unaffected by the binding removal). - cargo build --profile perry-dev -p perry -p perry-runtime-static -p perry-stdlib-static: clean; confirmed .a mtimes moved. - cargo check --workspace --all-targets (host-compatible exclusion set via workspace_architecture.py --print-excluded-scope) under -D warnings: clean. - cargo test -p perry-api-manifest: 39+4 passing (after retargeting the uuid-fixture test). - cargo test -p perry-codegen --test manifest_consistency: 5/5 passing. - cargo test -p perry --bin perry -- well_known: 27/27 passing. - cargo test -p perry-hir: full suite passing (test_lower_native_module_ registration uses "uuid" only as synthetic example data for a generic register/lookup mechanism — unaffected by the registry removal). - python3 scripts/binding_governance.py --check: OK (39 extension crates). - node scripts/binding_pins.mjs --check: OK (37 pinned, lock-step holds). - python3 scripts/workspace_architecture.py --check: OK. - python3 scripts/native_result_ledger.py: OK, 371 rows/322 providers unchanged (none of uuid's dispatch rows used a ledger-tracked NR_* kind). - python3 scripts/string_payload_access_inventory.py --write-baseline: perry-stdlib inline-offset 40 -> 38 (uuid.rs's own 2 sites). - Regenerated docs/api/perry.d.ts + docs/src/api/reference.md (perry --print-api-manifest) and docs/src/native-libraries/ governance.md (binding_governance.py --table) from the fixed manifest. - cargo fmt --all -- --check: clean. - scripts/run_lint_gates.sh (SKIP_COMPILE_GATES=1): 76 of 77 passed; the one failure (Public benchmark evidence freshness) is the pre-existing, known-red-on-every-PR gate per this campaign's contract. - Compile tier of run_lint_gates.sh (known-red on Linux per this campaign's contract). - Full gap suite (host stalls under auto-optimize per contract). - test-files/test_parity_uuid.ts is already excluded from the parity gate (test-parity/known_failures.json, "ci-env": Node's own oracle run fails ERR_MODULE_NOT_FOUND because uuid was never added to the repo's root package.json/package-lock.json — the same pre-existing gap documented for nanoid, #8271).
