Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This change adds native addon loading and dense numeric Map indexing, but the current implementation can authorize the wrong native binary, fail to load plugins on Apple targets, generate broken addon wrappers, expose incorrect typed-array behavior, retain stale objects across garbage collection, and cause severe performance regressions for descending Map inserts.

build_optional_runtimenow also runs when onlyctx.native_addonsis non-empty, but every diagnostic line inside it (starting with" wasm-host (no-auto): rebuilding runtime with wasm-host feature") still hardcodes the "wasm-host" label. A Node-API-only build (no WebAssembly usage) prints a message that names the wrong feature, which misleads anyone reading build output or debugging a failed rebuild.Compute the label from
runtime_features(or from the sameneeds_wasm_runtime/native_addonschecks) instead of a fixed string.✏️ Proposed fix

Line 402 excludes native-addon
.nodespecs from the emitted staticimportlist, the same way builtins are excluded at line 401. Builtins have a matching exclusion everywhere else that assumes animport_local_names[idx]binding exists; native-addon specs do not:
direct_named_reexports(around line 719-737) checksbuiltin_requires.contains(spec)and falls back to_cjs.{name}, but has no equivalent check forresolved_native_addon(source_path, spec).is_some(). For a shape likeexports.native = require('./addon.node'), this emitsexport { _req_N as native };, where_req_Nwas never declared as an import (since line 402 skipped it).import_aliases/alias_strip_ranges(around line 805-857) only runs when the module also hoists at least one top-level class — a realistic shape for a JS wrapper class around a native addon. It has the same missing native-addon check: it emitsconst alias = _req_N;(unbound_req_N) and blanks the original workingconst alias = require('./addon.node');line, so the binding is broken with no fallback.Both cases produce generated ESM that references an undeclared module-scope identifier, causing a compile failure or a runtime

- Around line 484-488: Fix the addressable-capacity calculation in the dense
expansion logic so it does not truncate 2^32 to zero when converting to usize on
32-bit targets. Since allowed already limits capacity to
DENSE_NUMERIC_MAX_SLOTS, remove the redundant addressable clamp and preserve the
existing target_len sizing based on needed, dense.slots.len(), and allowed.
- Around line 470-492: Update maybe_expand_dense to reserve headroom below the
requested integer and amortize descending expansions, rebuilding only when the
requested span exceeds the current dense capacity by the chosen growth factor;
preserve dense lookup behavior and addressable/allowed bounds. Add a regression
test covering contiguous descending inserts that verifies the dense base and
slot count change only a bounded number of times.
In `@crates/perry-runtime/src/node_api_host/buffers.rs`:
- Around line 300-324: Update the typed-array creation path around
js_typed_array_view to explicitly map NapiTypedarrayType discriminants to Perry
typed-array kinds instead of passing kind as i32, returning InvalidArg for
unsupported values. Also replace the reverse conversion near
TypedArrayHeader::kind with an explicit Perry-kind-to-Node-API mapping,
including handling KIND_FLOAT16 without transmuting it into NapiTypedarrayType.
In `@crates/perry-runtime/src/node_api_host/metadata.rs`:
- Around line 72-79: Update owner_from_bits to use the canonical
crate::value::addr_class::is_plausible_heap_addr predicate instead of the
hardcoded owner >= 0x10000 check, while preserving the existing non-pointer
early return and Option result behavior.
In `@crates/perry-runtime/src/node_api_host/promises.rs`:
- Around line 60-83: Update settle_deferred to keep the deferred promise
precisely rooted throughout settlement, rather than copying promise_bits into an
untracked raw pointer before marking the record settled and clearing its root.
Preserve the root while js_promise_resolve or js_promise_reject runs, then
refresh the Promise pointer from the rooted value after any callback-capable
work before further use.
In `@crates/perry-runtime/src/node_api_host/properties.rs`:
- Around line 67-75: Update the property-definition flow before the unsafe
std::slice::from_raw_parts call to return success immediately when count is
zero, including when properties is null; preserve the existing InvalidArg
validation for nonzero counts with null properties and continue preparing
descriptors for nonempty input.
In `@crates/perry-runtime/src/node_api_host/scopes.rs`:
- Around line 161-171: Reload the potentially relocated value from the
environment handle after js_weakref_new returns and before constructing
ReferenceRecord. Use the rewritten handle value for record.value_bits, while
preserving the existing weak_holder_bits behavior and with_env_mut flow.

In `@crates/perry-runtime/src/process/env_misc.rs`:
- Around line 308-315: The flags validation in the process.dlopen path must
reject NaN and fractional values instead of casting them to i64. Update the
condition around flags_value to obtain the raw f64 and accept only exact 0.0,
1.0, or 2.0 values, while preserving undefined and null handling; add regression
cases covering NaN and non-integer flags.
In `@crates/perry/src/commands/compile/collect_modules/native_addon.rs`:
- Around line 93-105: Constrain the declares_payload authorization check to the
candidate wrapper’s resolved dependency: resolve actual_name using that
wrapper’s Node resolution path, and only return allowed when the resolved
package directory exactly matches package_root. Keep the existing manifest
dependency checks, but prevent same-named packages elsewhere in the node_modules
tree from authorizing the payload.
In `@crates/perry/src/commands/compile/host_config.rs`:
- Around line 1265-1290: Update the native-addon target gate in the block
guarded by ctx.native_addon_packages to use the canonical is_android_target
classification instead of listing non-canonical Android names. Ensure android,
wearos, and android-x86_64 are rejected consistently while preserving the
existing unsupported-target handling for other platforms.
In `@crates/perry/src/commands/compile/link/mod.rs`:
- Around line 171-193: Update the export-list construction in the linking branch
to include the symbols from PLUGIN_HOST_SYMBOLS whenever ctx.needs_plugins is
true, alongside node_api_host_symbols. Ensure the generated exhaustive list
preserves both plugin-host exports and Node-API exports, while leaving behavior
unchanged when plugins are not needed.
- Around line 149-171: Update add_node_api_host_link_args and its callers to
accept Apple mobile target state for cross-iOS and cross-tvOS builds, then emit
direct ld64.lld flag forms instead of -Wl-wrapped arguments for those targets.
Preserve the existing Windows, Linux, Android, HarmonyOS, and cross-macOS
behavior.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win
Descending dense inserts rebuild the whole table on every set.
get and insert only treat a key as dense when integer >= dense.base. A key below base is out of range for any slot count, so it always reaches maybe_expand_dense, which lowers new_base and calls rebuild_dense. rebuild_dense allocates target_len slots and rescans all of hashed.
Descending insertion is the worst case. For for (let i = n; i >= 0; i--) m.set(i, v), base moves on every insert, so every insert pays a full rebuild: O(n^2) total with a large allocation constant. The doubling in target_len does not help, because the miss is caused by the base, not by the length. allowed also grows by 4 per key while needed grows by 1, so the target_len >= needed guard never stops the thrash. Before this change the same loop was a sequence of O(1) hashed inserts.
Reserve headroom below base and amortize the rebuild, for example by placing the new base a slack distance below integer and by rebuilding only when the requested span exceeds the current slot count by a factor.

addressable truncates to 0 on 32-bit targets.
u32::MAX as u64 + 1 is 2^32. The as usize cast truncates that to 0 on 32-bit targets when new_base == 0, so target_len becomes 0 and the target_len >= needed check fails. Dense expansion is then permanently disabled for zero-based key ranges on those targets. allowed already caps at DENSE_NUMERIC_MAX_SLOTS, so the clamp is redundant on 64-bit as well.
🛠️ Proposed fix

- .max(dense.slots.len().saturating_mul(2))

Node-API napi_typedarray_type enum numeric values napi_int8_array napi_uint8_clamped_array
💡 Result:
In the Node-API (formerly N-API) C header files, the napi_typedarray_type enumeration defines the underlying binary scalar data types for TypedArrays [1][2]. The numeric values assigned to these constants follow the order in which they are defined in the enumeration [3][4]. Based on the official definition in js_native_api_types.h, the numeric values for the requested types are: napi_int8_array: 0 [3][4] napi_uint8_clamped_array: 2 [3][4] For context, the complete enumeration mapping is as follows: napi_int8_array = 0 [3][4] napi_uint8_array = 1 [3][4] napi_uint8_clamped_array = 2 [3][4] napi_int16_array = 3 [3][4] napi_uint16_array = 4 [3][4] napi_int32_array = 5 [3][4] napi_uint32_array = 6 [3][4] napi_float32_array = 7 [3][4] napi_float64_array = 8 [3][4] napi_bigint64_array = 9 [3][4] napi_biguint64_array = 10 [3][4] These values correspond to the binary types supported by Node-API, which align with the TypedArray specifications in the ECMAScript Language Specification [5][6]. Addons should generally treat these enums as fixed-size 32-bit integers, and it is recommended to handle them via the provided enumeration constants rather than relying on hardcoded numeric literals in case of future extensions [2].

Map Node-API typed-array values explicitly.
NapiTypedarrayType does not use the Node-API discriminants. For example, Node-API assigns napi_uint8_clamped_array = 2 and napi_uint32_array = 6, but this enum assigns Uint8ClampedArray = 8 and Uint32Array = 5. Line 310 passes these values to js_typed_array_view, which interprets them as Perry kinds and can create the wrong typed-array type.
TypedArrayHeader::kind also includes KIND_FLOAT16 = 11, which has no NapiTypedarrayType variant. Line 359 can therefore transmute 11 into an invalid enum value, causing undefined behavior.
Use the actual Node-API discriminants and explicit mappings in both directions. Return NapiStatus::InvalidArg when a Perry kind has no Node-API equivalent.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use the canonical heap-floor predicate instead of >= 0x10000.
owner >= 0x10000 re-implements the address floor. The comment in crates/perry-runtime/src/map.rs (lines 618-620) states that > 0x10000 lets the whole handle band through and that is_plausible_heap_addr is the real floor. Handle-band addresses therefore become metadata owners here, so wrap data, external data, and type tags can attach to an address that is not a heap object, and napi_typeof can then report External for it.
🛠️ Proposed fix
let owner = value.as_pointer::<u8>() as usize;
- (owner >= 0x10000).then_some(owner)
+ crate::value::addr_class::is_plausible_heap_addr(owner).then_some(owner)Based on learnings: "use the canonical predicate crate::value::addr_class::is_plausible_heap_addr for the handle-band/heap-floor check. Do not duplicate lower-level address checks elsewhere."

Root and refresh the promise during settlement.
settle_deferred copies DeferredRecord::promise_bits into a raw pointer, then marks the record settled and clears its root. Settlement callbacks can run JavaScript and trigger moving GC. GC updates registered roots, but not the copied pointer, which js_promise_resolve and js_promise_reject continue to use. Keep a precise root live for the full operation and refresh the pointer after callback-capable work.

Rust reference float to integer cast NaN fractional truncates saturating semantics
💡 Result:
In Rust, casting a floating-point number to an integer using the as keyword follows well-defined, saturating semantics [1][2]. This behavior is specified as follows: 1. Truncation: The floating-point value is rounded towards zero [3][2]. 2. Saturation: If the value is outside the range of the target integer type, it is saturated to the minimum or maximum value of that integer type [1][3][2]. - Values greater than the maximum integer value (including positive infinity) saturate to the target type's maximum [3][2]. - Values smaller than the minimum integer value (including negative infinity) saturate to the target type's minimum [3][2]. 3. NaN Handling: NaN (Not-a-Number) values are converted to 0 [1][4][2]. These semantics were stabilized to avoid undefined behavior, which was a risk in earlier versions of Rust [4][3][5]. For cases where you require performance or alternative behavior, Rust provides the to_int_unchecked method on floating-point primitives (e.g., f32::to_int_unchecked) [1][6]. This is an unsafe operation that assumes the value is finite and fits within the target integer type; if these conditions are not met, the behavior is undefined [6]. Additionally, standard library methods such as to_int_saturating (if available in your toolchain) or checked conversion alternatives can be used for safer or more explicit handling [7].

Constrain payload authorization to the wrapper's resolved dependency.
Line 93 approves a payload by package name when any allowlisted wrapper in an ancestor node_modules declares that name. An unrelated nested package with the same name can pass this check if a legitimate allowlisted wrapper exists higher in the tree. This allows an unapproved native binary to cross the perry.nativeAddons boundary.
Resolve actual_name from each candidate wrapper's Node resolution path. Require the resolved package directory to equal package_root before returning the owner.

Use the canonical Android target classification.
is_android_target accepts android, wearos, and android-x86_64, but this gate checks the non-canonical android-arm64 and android-x64 names. Therefore, wearos and android-x86_64 bypass the rejection when native addons are configured.

LLVM ld64.lld command line -Wl, option direct linker invocation exported_symbols_list
💡 Result:
The LLD linker (specifically the Mach-O implementation) supports the -exported_symbols_list command-line option, which functions identically to the option provided by Apple's ld64 linker [1][2][3]. Functionality: The -exported_symbols_list option accepts a path to a file containing a list of global symbol names [4][1]. When this option is used, only the symbols specified in the file remain global in the final output file [4][1]. All other global symbols are treated as private externs (visibility=hidden) and are not exported [4][1]. Usage details: - File format: The file must contain one symbol name per line [4][1]. - Comments and whitespace: Lines starting with # are treated as comments and ignored; leading and trailing whitespace is stripped from the symbol names [4][1]. - Pattern matching: The linker supports simple shell-style wildcard patterns (e.g., *,?, [abc], [a-z]) within the symbol list file [4][1]. - Precedence: The exported list is compiled based on the provided command-line options. Using -exported_symbols_list or -exported_symbol overrides default export behavior [1][3]. This option is commonly used to reduce the size of dynamic libraries by restricting the public API to a defined set of symbols [5]. Top results: [4][1][3]

-exported_symbols_list conflicts with the plugin-host export surface on ld64.
On ld64 -exported_symbols_list is exhaustive: the linker exports only the listed names. This branch lists just the Node-API inventory. A build that sets both ctx.needs_plugins and a non-empty ctx.native_addons therefore loses the hone_host_api_* and js_* exports that PLUGIN_HOST_SYMBOLS force-keeps in crates/perry/src/commands/compile/link/build_and_run.rs (Lines 573-693). The -u flags there keep the symbols alive against dead-strip, but they do not put them back into the export trie. Plugin dylibs then fail to resolve host symbols at dlopen time.
Add the plugin-host symbols to the generated list when ctx.needs_plugins is true, or keep the full trie in that combination instead of passing an exhaustive list.

Security review of #8868
This one
dlopens native addon code, so the load path got a direct read rather than a description-level review.Verify-then-load ordering is correct.
verify_addon_payload(node_api_host/loader.rs:198) size- and SHA-256-checks every file in the payload, and is called at:424. Thedlopen/LoadLibraryExWhappens at:437, strictly after. Not the other way round.Path traversal is properly blocked.
safe_payload_pathcanonicalizes both the sidecar root and the candidate, then requirescanonical.starts_with(&root). That is a canonical-path containment check rather than a string prefix on unresolved input, so../escapes are rejected — and a missing file fails closed atcanonicalizerather than falling through.One gap probed, and it is closed by construction.
verify_addon_payloadhashesaddon.filesbut returnssafe_payload_path(root, &addon.entry); nothing at the load site assertsentry ∈ files, so in principle the file actually loaded could be one that was never hashed. In practice the staging step forecloses it:native_addon_sidecar.rs::addon_payload_fileswalks the package directory, and only walked files are both copied and hashed intofiles. An unhashed entry therefore was never staged, socanonicalizefails and the load errors out. Fail-closed — but it is an implicit invariant, not an asserted one. An explicit check that the resolved entry appears in the verified set would make the load path self-evidently safe instead of safe-by-distant-construction.Residual: a TOCTOU window exists between hashing and
dlopen(the file is read twice). Exploiting it requires local write access to the staged sidecar, so severity is low, but it is real and worth recording.Everything is behind
