📝 WalkthroughWalkthroughAdds a ChangesParcel Watcher Facade
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔴 Critical · up to The native watcher facade can lose subscribed callbacks during garbage collection and invoke stale memory, risking crashes or corrupted runtime behavior; direct imports and some supported targets also do not yet preserve the expected package behavior, while an overly broad addon exemption weakens build safety. These concrete compatibility and runtime issues must be fixed before merge. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@Cargo.toml`:
- Line 51: Update the workspace version in the [workspace.package] section of
Cargo.toml by incrementing the patch component, and update the adjacent
**Current Version:** line to the same new version.
In `@crates/perry-api-manifest/src/entries.rs`:
- Around line 190-200: Preserve the `@parcel/watcher` JavaScript wrapper by
removing the root package from the native entries in
crates/perry-api-manifest/src/entries.rs, while keeping platform sidecars
native. Update test-files/test_parcel_watcher_facade.ts to exercise ignore and
unsubscribe(), and revise docs/src/stdlib/other.md to document the root package
API rather than ignorePaths/ignoreGlobs. In js_parcel_watcher_subscribe and
js_parcel_watcher_unsubscribe, root callback before the first collection-capable
call, and root each event object before js_object_set_field or js_array_push.
In `@crates/perry-api-manifest/src/entries/part_2.rs`:
- Around line 11-42: Update the four `@parcel/watcher` method_sig
entries—subscribe, unsubscribe, writeSnapshot, and getEventsSince—to represent
options as an optional Any parameter instead of required p_any("options"),
preserving the declared signatures that allow calls without options.
In `@crates/perry-ext-parcel-watcher/Cargo.toml`:
- Around line 14-19: Keep fancy-regex as the local dependency requirement "0.18"
in the dependencies section rather than referencing the workspace catalog.
Update the workspace package version from 0.5.1514 to 0.5.1515 in the workspace
version declaration and the corresponding CLAUDE.md entry.
In `@crates/perry-ext-parcel-watcher/src/lib.rs`:
- Around line 630-712: Register CallbackRoot immediately after the callback == 0
validation in js_parcel_watcher_subscribe, before JsPromise::new and any
subsequent allocation or parsing. Preserve the handle through setup, release it
with drop_handle on every early-return path after registration, and remove the
late register_handle call before inserting the Subscription; use the handle’s
current callback address if later code requires it.
In `@crates/perry/src/commands/compile/cjs_wrap/wrap.rs`:
- Around line 1183-1237: Update target_node_arch so recognized Apple-family
targets without an explicit architecture, including ios, ios-simulator, tvos,
watchos, and visionOS, fall back to host_node_arch() instead of returning None;
preserve explicit x64/arm64 detection and unknown-target behavior. Add a
regression case covering an Apple-family target such as ios-simulator and
verifying fold_parcel_watcher_template_require produces the static watcher
specifier.
In `@crates/perry/src/commands/compile/collect_modules/native_addon.rs`:
- Around line 52-55: Update package_is_parcel_watcher_facade to recognize only
`@parcel/watcher` and the eight explicitly registered platform aliases, using the
shared alias canonicalization table if available; remove the broad
starts_with("`@parcel/watcher-`") match. Add a rejection test covering an
unregistered prefixed package such as `@parcel/watcher-untrusted` containing a
.node file.
In `@crates/perry/well_known_bindings.toml`:
- Around line 673-719: Update the documentation comment associated with the
Parcel watcher bindings to state that Perry supports the eight targets covered
by target_node_platform and target_node_arch, while the five other 2.5.1 sidecar
names are outside Perry’s target mapping; do not change the binding entries or
alias configuration.

Bump the workspace version.
This change edits Cargo.toml, and the PR description states that no version bump is included. The repository rule requires a patch increment in [workspace.package].version together with the **Current Version:** line above it. Add both edits.
As per coding guidelines: "Bump version: Increment patch in [workspace.package].version in Cargo.toml and the **Current Version:** line above."

Preserve the @parcel/watcher public wrapper contract.
Registering the root package as native bypasses its 2.5.1 JavaScript wrapper. Direct root imports therefore do not normalize ignore, resolve paths, or return { unsubscribe() } from subscribe.
- Keep the root wrapper compilable, or implement these semantics in the root facade. Keep platform sidecars native.
- Update
test-files/test_parcel_watcher_facade.tsto useignoreand callunsubscribe()on the returned subscription. - Update
docs/src/stdlib/other.mdto document the root package API, notignorePathsandignoreGlobs. - Root
callbackbefore the first collection-capable call injs_parcel_watcher_subscribeandjs_parcel_watcher_unsubscribe. Root each event object beforejs_object_set_fieldandjs_array_push.

Make the options parameters optional. @parcel/watcher 2.5.1 declares opts?: Options for all four methods, but p_any("options") emits a required parameter. Use an optional Any parameter for lines 16, 24, 32, and 40 so valid calls without options remain accepted.

Root the callback before the first site that can collect.
callback arrives as a raw GC address. register_handle(CallbackRoot { callback }) runs at Line 697. Before that, JsPromise::new() (Line 636), each promise.reject_string(...), and parse_options all allocate, so a collection can move the closure. After a move, the stored callback is a stale address, and fire_events calls JsClosure::from_raw on it.
Register the root immediately after the callback == 0 check, and release it on every early-return path.
🔒️ Proposed fix
- ensure_registered();
- let promise = JsPromise::new();
- let raw = promise.as_raw();
if callback == 0 {
+ ensure_registered();
+ let promise = JsPromise::new();
+ let raw = promise.as_raw();
promise.reject_string("`@parcel/watcher` subscribe callback must be a function");
return raw;
}
+ ensure_registered();
+ // Root before any allocating call: a copying collection may move the closure.
+ let callback_handle = register_handle(CallbackRoot { callback });
+ let promise = JsPromise::new();
+ let raw = promise.as_raw();
let Some(dir) = read_ptr_string(dir) else {
+ drop_handle(callback_handle);
promise.reject_string("`@parcel/watcher` directory must be a string");
return raw;
};Apply the same drop_handle(callback_handle) release to the remaining early returns, and delete the late register_handle at Line 697. Read the current address back from the handle if any later code needs it.
As per coding guidelines: "A GC-managed value's root store must dominate every subsequent site that can collect."

Fold Parcel watcher imports for all supported Apple targets.
At Line 1187, target_node_arch returns None for ios, ios-simulator, tvos, watchos, and visionOS targets. target_node_platform maps these targets to darwin. Therefore, fold_parcel_watcher_template_require exits at Line 1214 and leaves the dynamic require in the wrapped module. The literal-require extractor then cannot create the static facade import.
Use host_node_arch() for recognized platform targets that do not contain an explicit architecture. Add a regression case for an Apple-family target such as ios-simulator.

Restrict the native-addon exemption to registered aliases.
Line 54 accepts every package name that starts with @parcel/watcher-. A package such as @parcel/watcher-untrusted can declare that name and bypass refuse_node_addon_binary and compile-package addon rejection, even though it is not a facade sidecar.
Match the root package and the exact registered platform aliases. Prefer the shared alias canonicalization table if one exists. Add a rejection test for an unregistered prefixed package with a .node file.
PR objectives specify the root package plus eight platform aliases.

Document the supported Parcel watcher targets. target_node_platform and target_node_arch currently cover all eight listed sidecars. The five other 2.5.1 sidecars are outside Perry's target mapping. Update the comment to state this scope instead of claiming that all published sidecar names are aliases.

In `@crates/perry/well_known_bindings.toml` around lines 673 - 719, Update the
documentation comment associated with the Parcel watcher bindings to state that
Perry supports the eight targets covered by target_node_platform and
target_node_arch, while the five other 2.5.1 sidecar names are outside Perry’s
target mapping; do not change the binding entries or alias configuration.
