fix(runtime): honor collection iterator return overrides - #9127
Conversation
📝 WalkthroughWalkthroughThe runtime now routes only intrinsic Map and Set iterator methods through native dispatch. User-installed ChangesIterator dispatch correction
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The PR restores custom Map/Set iterator return handling, but inherited overrides can still be skipped for some valid JavaScript programs, leaving the behavior incorrect; the regression test helper also has a Windows archive-path mismatch. Merge should wait for these issues to be fixed or explicitly accepted. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@crates/perry-runtime/src/object/native_call_method/collection_methods.rs`:
- Around line 400-410: Update the raw-pointer Map/Set iterator handling in
js_native_call_method and dispatch_raw_pointer so return calls that are not
resolved by intrinsic dispatch continue through prototype lookup, including
inherited methods set via Object.setPrototypeOf, and invoke the resolved method
with the iterator as this. Preserve existing intrinsic and own/class-vtable
dispatch behavior.
In `@crates/perry/tests/issue_9098_collection_iterator_close.rs`:
- Around line 24-27: Update target_debug_dir() to match the directory used by
ensure_runtime_archive(): use target/debug when cargo builds without an explicit
target, or consistently pass and derive the same explicit target for both
operations so PERRY_RUNTIME_DIR points to the generated runtime archives.

Route raw-pointer Map/Set iterator calls through prototype lookup. For a raw-bitcast Map or Set iterator, dispatch_raw_pointer excludes return from intrinsic dispatch and checks only own fields and class-vtable entries. If those lookups miss, js_native_call_method skips resolve_inherited_field because the raw pointer bits are not a JSValue::is_pointer() value. Therefore, Object.setPrototypeOf(iterator, proto).return() can bypass the inherited method instead of invoking it with the iterator as this.

Derive the Windows runtime archive directory. .cargo/config.toml does not set build.target, and ensure_runtime_archive() runs cargo build without --target, so Windows archives can be written to target/debug. target_debug_dir() instead selects target/x86_64-pc-windows-msvc/debug, so PERRY_RUNTIME_DIR may not contain the archives. Derive the path from Cargo’s effective target or pass the same target to the archive build.

Merged as part of a six-PR merge train: all six were cherry-picked onto one branch and validated together in a single build rather than six separate ones, at the maintainer's request to speed up a backlog.
