feat: host allowlisted Node-API v8 addons - #8868
Conversation
📝 WalkthroughWalkthroughThis change adds an opt-in Node-API v8 host for approved prebuilt native addons. It adds addon policy and sidecar staging, authenticated runtime loading, Node-API APIs, lifecycle and concurrency support, linker exports, compiler integration, and end-to-end validation. ChangesNode-API host and native addon support
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR enables host-loaded Node-API addons and changes runtime, packaging, and linker behavior. The current head still has unresolved issues that can cause resource exhaustion, invalid memory access, incorrect addon selection, broken macOS plugin resolution, unsupported static-musl builds, and invalid generated CommonJS bindings. It is not merge-ready until the major correctness, security, and availability issues are fixed. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@crates/perry-runtime/src/gc/dead_owner.rs`:
- Around line 404-409: Update the entry-count assertion in
the_dead_key_prune_registry_keeps_its_shape to account for feature-dependent
DEAD_KEY_PRUNES contents: require 19 entries only when node-api-host is enabled,
and accept 18 entries for default-feature builds.
In `@crates/perry-runtime/src/node_api_host/async_work.rs`:
- Around line 138-159: Replace the per-request std::thread::spawn in the async
work queuing path with a fixed-size bounded worker pool or executor, ensuring
execute callbacks run through that pool instead of creating one native thread
per napi_queue_async_work call. Preserve the existing ACTIVE_WORK accounting,
WORK_QUEUED to WORK_RUNNING state transition, callback invocation,
WORK_COMPLETING transition, and enqueue_completion owner-thread completion flow.
- Around line 189-196: Update
crates/perry-runtime/src/node_api_host/async_work.rs:189-196 around
napi_delete_async_work so deleted async work is reclaimed after both deletion
and completion. In crates/perry-runtime/src/node_api_host/tsfn.rs:156, avoid
retaining a strong Arc for every TSFN, and in
crates/perry-runtime/src/node_api_host/tsfn.rs:359-385 remove or weaken the
environment entry during TSFN finalization so destroyed resources are not
retained.
In `@crates/perry-runtime/src/node_api_host/buffers.rs`:
- Around line 8-22: Update NapiTypedarrayType to use Node-API numeric
assignments, including Uint8ClampedArray = 2 and shifting subsequent variants
accordingly, then add an explicit checked Node-API-to-runtime mapping before
js_typed_array_view in napi_create_typedarray. Replace the unchecked transmute
in napi_get_typedarray_info with validation that rejects unsupported runtime
kinds, including KIND_FLOAT16, and returns NapiStatus::InvalidArg.
In `@crates/perry-runtime/src/node_api_host/lifecycle.rs`:
- Around line 52-57: Update the NODE_VERSION initializer used by
napi_get_node_version to set major, minor, and patch to 22, 0, and 0
respectively instead of reading the workspace package version; retain release as
c"perry".
In `@crates/perry-runtime/src/node_api_host/loader.rs`:
- Around line 162-169: Update the suffix fallback around suffix_matches so
logical_id and entry matches are accepted only when the matched suffix starts at
a path-segment boundary (or equals the entire request), preventing matches
embedded within another segment while preserving valid unique-addon resolution.
In `@crates/perry-runtime/src/node_api_host/promises.rs`:
- Around line 53-70: Update the deferred settlement logic around env.deferred
and env.deferred_mut to read promise_bits and mark the record settled in one
mutable lookup, returning NapiStatus::InvalidArg when the record is missing or
already settled; only invoke resolve or reject with the promise value obtained
from that successful lookup.
In `@crates/perry-runtime/src/node_api_host/properties.rs`:
- Around line 67-75: Update prepare_descriptors to return Ok(Vec::new()) when
count is zero before calling from_raw_parts, while retaining the existing
invalid-argument error for null properties when count is nonzero.
In `@crates/perry-runtime/src/node_api_host/scopes.rs`:
- Around line 226-240: Update napi_reference_ref’s collected-weak-target branch
in the holder_bits handling to return NapiStatus::InvalidArg instead of ok(env),
while preserving the result reset behavior. Keep the existing invalid status for
a dead reference and the live-target path unchanged.
In `@crates/perry-runtime/src/node_api_host/tsfn.rs`:
- Around line 164-178: Update napi_get_threadsafe_function_context to remove the
owner_env check so valid TSFN handles can return their context from any thread,
while preserving null-result and invalid-handle validation. Add a regression
test that retrieves the context from a spawned worker thread.
- Around line 337-349: Update the fallback invocation in the call_js_cb branch
to obtain the JavaScript undefined value with napi_get_undefined and pass it as
the receiver to napi_call_function, instead of retrieving and passing the global
object via napi_get_global. Preserve the existing aborted and null-function
checks.
In `@crates/perry/src/commands/compile/collect_modules/native_addon.rs`:
- Around line 83-107: The approved_owner_package logic must verify package
identity before granting ownership: for each candidate wrapper, resolve the
declared dependency using that wrapper installation’s Node resolution context,
canonicalize the resolved package root, and compare it with package_root before
returning the approved package. Preserve dependency checks for dependencies and
optionalDependencies, and add a regression test rejecting an unrelated nested
payload with the same name.
In `@crates/perry/src/commands/compile/host_config.rs`:
- Around line 1265-1290: Update the native_addon_packages validation to reject
static musl targets (`linux-musl`, `linux-x86_64-musl`, and
`linux-aarch64-musl`) when `--libc musl` is selected. Refactor the platform
check to use the existing `is_android_target` helper instead of duplicating
Android target names, while preserving rejection of all currently unsupported
targets and covering `android-x86_64` and `wearos`.
In `@crates/perry/src/commands/compile/link/mod.rs`:
- Around line 149-196: Update add_node_api_host_link_args so the macOS export
list includes PLUGIN_HOST_SYMBOLS alongside node_api_host_symbols when
ctx.needs_plugins is true. Preserve the existing platform-specific flags and
ensure the generated list exports both symbol groups for dynamically loaded
plugins.
In `@crates/perry/src/commands/compile/optimized_libs/freshness.rs`:
- Around line 520-527: Update input_newer_than to exclude target, .git, tests,
benches, and examples consistently with auto_optimized_archives_are_fresh, so
files added under those directories do not invalidate optimized runtime
freshness.
- Around line 433-446: Update auto_optimized_source_fingerprint to include
crates/perry-runtime/src/gc/tests, keeping it aligned with RUNTIME_BUILD_INPUTS
and source_build_id so changes there invalidate the auto-optimized stamp.
Alternatively, remove that directory from RUNTIME_BUILD_INPUTS, but preserve
consistent hashing between both paths.
In `@crates/perry/src/commands/compile/optimized_libs/no_auto.rs`:
- Around line 56-57: Update build_optional_runtime diagnostics to describe the
features actually selected, including native-addons-only builds instead of
always reporting wasm-host. Construct runtime_features before the rebuild
message, use it in that message and all related diagnostics, and rename the
wasm-host-specific prefixes and wasm_host_target_dir local to feature-neutral
names.

Use a bounded executor for async work.
Line 139 creates one native thread for each successful napi_queue_async_work call. Repeated queueing can create an unbounded number of native threads. This can exhaust process resources and stop the runtime.
Route execute callbacks through a fixed-size worker pool. Keep the existing owner-thread completion queue.

Node.js napi_typedarray_type enum order js_native_api_types.h napi_uint8_clamped_array
💡 Result:
In the Node.js Node-API (formerly N-API), the napi_typedarray_type enum is defined in the js_native_api_types.h header file [1][2]. The napi_uint8_clamped_array member is positioned third in the enumeration, following napi_int8_array and napi_uint8_array [1][3]. As of the current implementation, the order of the napi_typedarray_type enum is as follows [1][2]: 1. napi_int8_array 2. napi_uint8_array 3. napi_uint8_clamped_array 4. napi_int16_array 5. napi_uint16_array 6. napi_int32_array 7. napi_uint32_array 8. napi_float32_array 9. napi_float64_array 10. napi_bigint64_array 11. napi_biguint64_array 12. napi_float16_array (conditionally defined) [1][3] This enum represents the underlying binary scalar data type of a JavaScript TypedArray [4][5]. While the order is fixed in the header, Node-API documentation generally advises that new enum values are added to the end of such definitions to maintain ABI stability [6]. Binding generators (such as those used in Rust crates like nodejs-sys) typically map these to integer values starting at 0, making napi_uint8_clamped_array equal to 2 [7][8].

Use Node-API numbering and a checked conversion.
Node assigns napi_uint8_clamped_array the value 2, but NapiTypedarrayType assigns that value to Int16Array. napi_create_typedarray passes this value directly to js_typed_array_view, which uses it as Perry's internal kind. Values 2 through 8 therefore create the wrong typed-array kind. Add an explicit Node-API-to-runtime mapping.
napi_get_typedarray_info transmutes the stored u8 kind without validation. Perry also uses kind 11 for KIND_FLOAT16, so the transmute can receive a discriminant that is invalid for NapiTypedarrayType and cause undefined behavior. Replace it with a checked conversion and return NapiStatus::InvalidArg for unsupported kinds.

musl libc static linking dlopen unsupported non-functional stub Node.js native addons
💡 Result:
The limitation regarding dlopen in statically linked binaries using musl libc stems from a fundamental design choice: musl does not support dynamic loading within a fully static executable [1][2][3]. Because a fully static binary contains all necessary libraries and symbols linked at compile-time, it lacks the dynamic linker/loader infrastructure (ld-musl) required to resolve and load shared objects (.node native addons) at runtime [2][4][5]. Key Technical Realities: 1. Dynamic Loading is Unsupported: When Node.js is compiled with the --fully-static flag, it is unable to perform dynamic loading [1][6]. The dlopen() function, which Node.js uses to load native addons, is either stubbed out or will fail with errors like "dynamic loading not supported" because the required runtime environment for resolving symbols against the host system is missing [1][2][3][5]. 2. ABI Incompatibility: Even if dlopen were functional in a static binary, there are significant risks regarding ABI (Application Binary Interface) compatibility [4][7]. If a static binary and a dynamically loaded module each attempt to use different versions of libc or other shared libraries, it can lead to memory corruption, heap clobbering, or crashes due to inconsistent internal data structures [4][7]. 3. Impact on Native Addons: Node.js native addons (compiled as .node files, which are shared objects) require a dynamic loader to be brought into the application's process space [2][8]. Consequently, they cannot be loaded into a fully static Node.js process [1][6]. Workarounds and Best Practices: If your application requires both the portability of static linking and the functionality of native addons, consider these strategies: * Avoid "Fully Static" for the Runtime: Maintain a dynamically linked Node.js binary (e.g., the standard musl-based builds provided for Alpine Linux) [3]. This allows the OS's dynamic linker to manage the loading of both the Node.js runtime and its native addons [3][8]. You can still keep other parts of your infrastructure static if necessary [9]. * Dynamic CRT Linking for Addons: When building native addons (e.g., using Rust/napi-rs) for musl targets, ensure the addon itself is linked dynamically against musl libc (by disabling static CRT features like -C target-feature=-crt-static), even if your main binary remains static [10][11][9]. This allows the addon to interact correctly with the musl loader at runtime [9]. * Native Environment Builds: Always compile native addons within the target environment (e.g., inside an Alpine Linux container) [9][8]. Cross-compiling from a glibc-based host often results in binaries that expect a glibc interpreter (ld-linux-x86-64.so.2) instead of the required musl loader (ld-musl-x86-64.so.1), causing ERR_DLOPEN_FAILED [9][8]. In summary, the "dynamic loading not supported" error is the expected behavior for fully static musl binaries [3]. To use native addons, you must move away from a "fully static" architecture for the Node.js runtime [1][2].

Reject static musl targets when perry.nativeAddons is configured.
--libc musl produces fully static linux-musl, linux-x86_64-musl, or linux-aarch64-musl binaries. Static musl binaries cannot load .node sidecars through process.dlopen(). Add these targets to the unsupported list.
Use is_android_target instead of duplicating the target list. It recognizes android, android-x86_64, and wearos, but the current list omits android-x86_64 and wearos.

The Apple ld64 linker does not use a "whitelist" file in the sense of a proprietary, uniquely-named configuration setting; rather, it uses the -exported_symbols_list flag to define a list of symbols to be kept as global in the final output file [1]. ### Core Mechanism When -exported_symbols_list <filename> is provided to ld64, all global symbols not present in that file are treated as private_extern (visibility hidden) and are excluded from the exported symbol table of the resulting binary [1]. ### Key Details * Format: The file should be a plain text file with one symbol name per line [2][1]. * Comments and Whitespace: Leading and trailing whitespace is ignored, and lines starting with # are treated as comments [1]. * Wildcards: The linker supports shell-style wildcards within the list (e.g., * for zero or more characters, ? for a single character, and bracket expressions like [a-z]) [1]. * Alternative Options: * -exported_symbol <symbol>: Allows you to specify individual symbols directly on the command line instead of using a file [1]. * -unexported_symbols_list <filename>: The inverse approach, where you specify symbols to be hidden (forced to private extern) while leaving others global [2][1]. * -no_exported_symbols: Introduced in Xcode 14 (ld64 816), this flag explicitly instructs the linker to export no symbols, which is useful for main executables that do not provide a library interface [3]. ### Usage in Xcode You can configure this in Xcode by setting the "Exported symbols file" build setting to the path of your text file [2]. Xcode automatically passes the -exported_symbols_list argument to the linker during the build process [2]. ### Important Considerations * Mixing Options: You cannot use both "exported" and "unexported" options in the same linker invocation; doing so will result in an error [4][3]. * Symbol Names: Ensure the symbol names in your text file include the required underscore (_) prefix, as is standard for Mach-O symbols [5]. * Visibility Attributes: While the linker flags control the final export state, you can also use compiler-level attributes like attribute((visibility("default"))) and attribute((visibility("hidden"))) or the -fvisibility=hidden compiler flag to manage visibility at the source code level [2][5]. The linker's export list serves as the final, authoritative filter.

Merge plugin-host symbols into the macOS export list.
When ctx.native_addons is non-empty, the macOS branch passes an export list containing only Node-API symbols. If ctx.needs_plugins is also true, the -u flags in build_and_run.rs keep PLUGIN_HOST_SYMBOLS alive but do not export them. ld64 hides global symbols that are absent from -exported_symbols_list, so dynamically loaded plugins may fail to resolve these host symbols. Include PLUGIN_HOST_SYMBOLS in the macOS export list.

Align the fingerprint with RUNTIME_BUILD_INPUTS. source_build_id hashes crates/perry-runtime/src/gc/tests, but auto_optimized_source_fingerprint excludes it. A test change can leave the auto-optimized stamp unchanged while a rebuilt runtime gets a different PERRY_RUNTIME_BUILD_ID. The compatibility check then rejects the cached archive instead of rebuilding it. Exclude these directories from RUNTIME_BUILD_INPUTS or include them in this fingerprint.

input_newer_than still walks tests, benches, and examples, so the stated goal is not reached.
The comment says "Same exclusions as input_newer_than", but input_newer_than at lines 603-626 skips only target and .git. auto_optimized_archives_are_fresh passes crates/perry-runtime and crates/perry-stdlib to that walk. A new file under crates/perry-runtime/tests/ therefore makes input_newer_than return true, the freshness gate fails, and the optimized runtime rebuilds — exactly the case this exclusion tries to avoid. Only the stamp half of the gate honors the new exclusion.
Add the same exclusions to input_newer_than, or correct the comment.

Update the diagnostics: they still claim a wasm-host rebuild.
build_optional_runtime now also runs when only native addons are present. Every message in the function still uses the wasm-host (no-auto) prefix, and line 102 prints "rebuilding runtime with wasm-host feature" unconditionally. A user who compiles a Node-API addon with PERRY_NO_AUTO_OPTIMIZE=1 and no WebAssembly sees a statement that does not match the build.
Report the features actually selected.
🐛 Proposed fix
if matches!(format, OutputFormat::Text) {
- println!(" wasm-host (no-auto): rebuilding runtime with wasm-host feature");
+ println!(
+ " optional-runtime (no-auto): rebuilding runtime with features {}",
+ runtime_features.join(",")
+ );
}This requires moving the runtime_features construction (lines 117-123) above the message. Rename the remaining wasm-host (no-auto) prefixes and the wasm_host_target_dir local for consistency.
Also applies to: 78-79, 108-108, 117-123, 132-132
