Summary

Make Perry compile and run OpenCode from its full TypeScript source and dependency graph, without relying on a minified JavaScript bundle. The raw graph exposed several independent lowering, source-graph, codegen, runtime, and Windows-link gaps; this PR fixes those gaps and adds focused regressions for the real dependency shapes.

The acceptance build compiled 7,136 native modules with 0 JavaScript fallbacks, then produced an OpenCode executable whose --version and --help commands both exited successfully.

Changes

  • Preserve ESM semantics across the source graph: hoist static import bindings, keep dynamic imports out of eager init ordering, erase all-type named specifier imports at runtime while retaining their metadata, and include that distinction in stable/object-cache hashes.
  • Scope namespace-exported functions, variables, and classes by namespace in compiler registries. This prevents equal bare names from unrelated direct imports or other namespaces from replacing one another, including through named and export * barrels.
  • Fix class and closure lowering used by OpenCode dependencies: forward module-level class-expression references, initialize inherited dynamic class expressions in the correct order, box shared optional captures at nested-closure entry, and statically recognize the CJS-wrapper lru-cache constructor destructure.
  • Keep ambiguous .values() calls on generic iterator dispatch instead of specializing them as arrays; retain regression coverage for inherited iterator helpers on MapIterator (the implementation itself is now supplied by current main).
  • Fix runtime class/object behavior used by Effect: preserve Object.setPrototypeOf links for ClassRefs, find inherited computed static fields for generic in, and allow clearing those links.
  • Fix runtime correctness at dependency startup: root unresolved-global lookup names across lazy globalThis allocation, translate split surrogate ranges in regex character classes, and pass both user rest arguments and synthetic arguments arrays through bound method dispatch.
  • Harden compilation and linking: make namespace ownership part of object-cache identity, limit PERRY_DEBUG_INIT invalidation to the entry object, fingerprint explicit object inputs without quadratic path scans, keep CJS class-hoist scanning synchronized across regex quotes, and rewrite duplicate COFF wrapper symbols with relocation-safe renames.

Test plan

  • cargo fmt -p perry-hir -- --check, cargo fmt -p perry-codegen -- --check, cargo fmt -p perry-runtime -- --check, and cargo fmt -p perry-transform -p perry -- --check
  • LLVM_SYS_221_PREFIX=C:\llvm cargo check -p perry-codegen -p perry-runtime -p perry
  • LLVM_SYS_221_PREFIX=C:\llvm cargo build --release -p perry-runtime-static -p perry-stdlib-static
  • cargo test -p perry-hir --lib — 364 passed, 1 ignored
  • cargo test -p perry-runtime --lib — 2,752 passed, 4 ignored
  • All newly added focused compiler-driver and end-to-end regressions pass, including class-expression forwarding, ClassRef prototype inheritance, nested capture boxing, bound rest + arguments, namespace scoping, import/init ordering, type-only imports, regex translation, cache identity, CJS scanning, and COFF symbol rewriting.
  • Full OpenCode source/dependency compile — 7,136 native modules, 0 JavaScript fallbacks; generated executable passes --version and --help.
  • cargo build --release clean — the affected release runtime and stdlib archives were built; the entire multi-platform workspace was not built locally.
  • cargo test --workspace --exclude perry-ui-ios --exclude perry-ui-tvos --exclude perry-ui-watchos --exclude perry-ui-gtk4 --exclude perry-ui-android --exclude perry-ui-windows passes — not run. Broad Windows runs found unrelated/current-main failures: perry CLI tests reached 1,036 passed / 20 failed (POSIX command/path assumptions, permission tests, and cascading poisoned env locks); perry-codegen reached 1,345 passed / 3 failed in existing platform-sensitive object-byte/IR assertions; the source-graph suite reached 19 passed / 2 failed in existing trace assertions that do not recognize current $pshape output.
  • Added focused tests in the affected crates and crates/perry/tests.
  • No public CLI, stdlib, or runtime API documentation change is required.
  • No platform UI backend was touched.

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds namespace-scoped import metadata, runtime-erased import tracking, class-expression and closure lowering fixes, runtime GC and inheritance corrections, regex and iterator regressions, and Windows archive-linking updates.

Changes

Compiler source compatibility

Layer / File(s) Summary
Namespace identity and import propagation
crates/perry-codegen/src/codegen/*, crates/perry-hir/src/*, crates/perry/src/commands/compile/*
Namespace members use scoped metadata. Type-only imports can be runtime-erased across lowering, initialization, validation, and caching.
HIR binding and class lowering
crates/perry-hir/src/lower/*, crates/perry-codegen/src/lower_call/*
Static imports, forward class expressions, closure captures, array-method dispatch, CJS destructuring, and dynamic heritage receive updated lowering.
Regression coverage
crates/perry/tests/*, crates/perry-hir/src/lower/tests.rs
Tests cover namespace ABI isolation, import behavior, class expressions, captures, array dispatch, CJS constructors, and rest dispatch.

Runtime corrections

Layer / File(s) Summary
GC-safe global and method dispatch
crates/perry-runtime/src/error.rs, crates/perry-runtime/src/object/class_registry/dispatch.rs
Runtime values are rooted across collection-capable operations. User-rest and synthetic arguments arrays use separate ABI slots.
Class prototype and inherited-property handling
crates/perry-runtime/src/object/class_registry/*, crates/perry-runtime/src/object/field_get_set/*, crates/perry-runtime/src/object/object_ops/*
Class-reference prototype links can be stored and cleared. Inherited static data participates in property checks.
Regex and iterator behavior
crates/perry-runtime/src/regex/grammar.rs, crates/perry-runtime/src/iterator_helpers/tests.rs
Surrogate folding tracks character-class state. Iterator-helper flattening receives regression coverage.

Initialization diagnostics and build tooling

Layer / File(s) Summary
Entry diagnostics and cache keys
crates/perry-codegen/src/codegen/entry.rs, crates/perry/src/commands/compile/object_cache*
PERRY_DEBUG_INIT output moves to the entry initializer chain. Cache keys include entry-only debug settings and namespace-owned imported classes.
CJS scanning and archive rewriting
crates/perry/src/commands/compile/cjs_wrap/*, crates/perry/src/commands/compile/strip_dedup/*
CJS scans mask source contents. Archive rewriting detects COFF members from object bytes and supports Windows symbol rewriting.
Canonical object identity matching
crates/perry/src/commands/compile/link/link_cache.rs
Link-cache matching uses canonical absolute object identities.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 60cb4

This PR enables broader source compilation but still changes runtime prototype and garbage-collection behavior in ways that can silently lose prototype updates, expose incorrect inherited properties, or crash during allocation; Windows linking and several compiler edge cases also remain unresolved. These are high-impact merge-readiness risks that should be fixed or explicitly accepted before merging.

768-768: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Fix static bound dispatch for methods that use both ...rest and arguments.

At crates/perry-codegen/src/codegen/string_pool.rs:768, registration checks only the final parameter. HIR places the synthetic arguments parameter after a user rest parameter, so registration omits the user-rest flag. Static dispatch then binds scalar arguments to the wrong parameter slots. Propagate separate user-rest and synthetic-arguments metadata through static_method_triples and dispatch, and add a bound-method regression test.

Do not suppress a namespaced static-field import for a bare local class.

This check compares the local class name with bare ic.name. If class Token {} is local and import * as Plugin exposes Plugin.Token, this branch skips registration of Plugin.Token static fields. Compare against effective_name so only an actual registry-key collision takes precedence.

Keep arguments-length metadata namespace-scoped.

Line 1684 registers method_arguments_length_only under bare ic.name even when ic.namespace is set. A namespace member can then enable the arguments-length ABI for an unrelated direct import with the same class and method names. Guard this insertion with ic.namespace.is_none(), like the adjacent method ABI registries.

Do not reuse runtime_erased imports for runtime bindings.

Both localizers treat runtime_erased imports as active. They can mark a required binding as satisfied or append its specifier to an erased import. The compile pipeline excludes that import from runtime binding and initialization processing, so the localized ExternFuncRef can lack its runtime dependency.

Apply the runtime_erased check at all four listed sites. Add a regression fixture for a type-only import and a localized function that uses a runtime export from the same module.

384-396: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Extract the repeated namespace-function-metadata resolution into one helper.

Three sites compute the same value: a scoped namespace_member_func_key(namespace, member) lookup into imported_func_param_counts, a fallback to the bare member key, then a has_rest selection gated on which lookup matched. This PR had to update all three sites together for the same fix, which shows the duplication already costs a synchronized edit on every future change to this logic.

Do not treat shadowed Array or Object methods as array producers.

chain_roots_at_array recognizes Array.from and Object.values by identifier text only. A local, function, or import can shadow either global. For example, a local Object.values() can return a Map; the outer .values() then passes this gate and lowers to Expr::ArrayValues.

Require that Array or Object is unshadowed before accepting these calls as array roots.

Record every valid ClassRef prototype representation.

Line 383 records only a non-closure heap object. However, proto_ok also accepts a declared-class ClassRef, a function closure, and a Proxy. For Object.setPrototypeOf(Child, ParentClass), this branch does not store a link. The later paths cannot handle a ClassRef target. The function then returns Child as if the update succeeded.

Store a rooted JSValue prototype representation for ClassRef targets, or add equivalent handling for ClassRefs, closures, and Proxies. Route static property lookup through that representation.

Regression case
class Parent {}
(Parent as any).value = 1;

class Child {}
Object.setPrototypeOf(Child, Parent);

console.log((Child as any).value); // must print 1

Prevent folding from starting on an escaped character.

fold_surrogate_pairs evaluates at_unit_start before updating escaped. For r"\\uD800\uDC00", it folds the escaped \uD800 with \uDC00, changing the literal pattern into an astral-character match. Add !escaped to the condition and regression tests for escaped backslashes and brackets.

Make COFF renamed symbols unique per archive path.

build_and_run_link preserves distinct archive paths, but strip_duplicate_objects_from_well_known_lib derives archive_tag only from file_name(). Two same-basename .lib archives can therefore receive identical renamed definitions when their member and symbol indexes match. If both members are extracted, lld-link may fail with duplicate definitions.

Derive the tag from a stable digest of the canonical archive path. Add a Windows regression for same-basename archives in separate directories.

Update strip_duplicate_objects_from_well_known_lib so archive_tag incorporates a
stable digest of the archive’s canonical path, while retaining the existing
filename sanitization, ensuring same-basename archives produce distinct COFF
symbol names. Add a Windows regression covering same-basename .lib archives in
separate directories.

The well-known-wrapper strip-dedup path decided COFF from the archive's
`.lib` extension. It is handed perry's own intermediate, which
`strip_duplicate_objects_from_no_shared_deps` names
`_<lib>_nosharedeps.lib` on EVERY host — so macOS and Linux took the
Windows branch, `llvm-ar --format=coff` wrote a GNU-style symbol table,
and `ld` rejected the archive:

    ld: archive member '/' not a mach-o file in _libperry_ext_ws.a_nosharedeps.lib

Read the container from an extracted member's magic bytes instead
(`object_format::object_is_coff`), so `--redefine-sym` / `--format=coff`
stay Windows-only. Full OpenCode source-graph build now links on macOS:
2,954 modules, 0 JavaScript fallbacks, 235 MB executable.

- Split five files back under the 2,000-line gate: error.rs,

- Guard the new ClassRef `Object.setPrototypeOf` store with
  `is_above_handle_band` + `try_read_gc_header` before `is_valid_obj_ptr`.
  `proto` is user-supplied and lands in a GC root table the collector

Audit + 3 mechanical fixes pushed (15887807ed)

Audited on macOS (arm64) against merge-base 07dee0fd29. The compiler work here is solid — namespace scoping, the import pre-pass, the iterator narrowing and the init-order change all matched Node in every probe. Two defects and some CI debt; I pushed fixes for the CI debt and for the one that blocked this PR's own goal.

Fixed in 15887807ed

1. macOS linking was broken by this PR. strip_duplicate_objects_from_well_known_lib decided COFF from the archive's .lib extension, but it is handed perry's own intermediate, which strip_duplicate_objects_from_no_shared_deps names _<lib>_nosharedeps.lib on every host. So macOS/Linux took the Windows branch, llvm-ar --format=coff wrote a GNU symbol table, and ld rejected it:

ld: archive member '/' not a mach-o file in _libperry_ext_ws.a_nosharedeps.lib

Isolated repro: llvm-ar --format=coff crs coff.lib x.o then linking gives that exact error, while plain ar crs links fine. Now read from an extracted member's magic bytes (strip_dedup/object_format.rs). With this fix the full OpenCode source graph links on macOS: 2,954 modules, 0 JavaScript fallbacks, 235 MB executable. This is likely why the acceptance run was Windows-only.

2. perry-transform lib tests did not compile — 5 × E0063 missing field runtime_erased. This red-lined cargo-test/warnings, and fail-fast then cancelled check, e2e-scoped, gc-stress-build and gap-suite-build, so those four jobs never actually ran on this PR.

3. Lint gate. The size gate fails on four files, not one — error.rs (2037), property_get.rs (2005), module_decl.rs (2072), cjs_wrap/tests.rs (2014); all split (plus strip_dedup.rs, which my own fix pushed over). Also cleared the addr-class ratchet and recorded the test_only verdict for the new TEST_COLLECT_BEFORE_GLOBAL_THIS_ALLOC holder.

On the ratchet specifically — that one is not just style. proto is user-supplied and is stored into a GC root table the collector later dereferences; a bare is_valid_obj_ptr accepts the fetch/zlib/proxy handle bands on Linux (segfault there, hidden on macOS). Now guarded with is_above_handle_band + try_read_gc_header.

Verified: cargo fmt --check, cargo check --all-targets, size gate, addr-class audit and gc_runtime_root_holders all clean; perry-transform 121, perry-hir 364, perry-runtime 2,825, perry bin 1,068 tests pass.

Still open — please take a look

A. Object.setPrototypeOf(Ctor, obj) leaks onto instances. It stores obj in CLASS_PROTOTYPE_OBJECTS, which carries instance-prototype meaning, so a constructor-side link becomes an instance-side one:

const schema = { ast: "STATIC-ONLY", greet() { return "static-only"; } };
class Opaque {}
Object.setPrototypeOf(Opaque, schema);
const inst = new Opaque();
//                    node        this PR        merge-base
// inst.ast           undefined   STATIC-ONLY    undefined
// typeof inst.greet  undefined   function       undefined
// inst.greet()       TypeError   "static-only"  TypeError

Same root cause, second symptom — it mutates the user's object: after Opaque.prototype.added = fn, Object.keys(schema) is ["ast","added"] (Node: ["ast"]), because prototype-method mirroring writes through that table.

This hits the PR's own target: Effect does Object.setPrototypeOf(Class, schema) at Schema.ts:1887 and :5874. The new test asserts only the static side, which is why it passed. Suggested fix: give the constructor [[Prototype]] its own table that instance walks don't read, and assert new Ctor() does not see the prototype's members.

Related, the fix is partial: Ctor.staticMethod() called directly on the class ref still throws is not a function (Node returns the value), though the same call via an any-typed alias works. Object.getPrototypeOf(Ctor) also still returns the wrong value (pre-existing).

B. The linked binary does not start. --version and --help both exit 1 with TypeError: recur is not a function. Caveat on attribution: my graph is 2,954 modules rather than the harness README's 2,454, because patches/dependency-compat.patch no longer applies to the locked Effect version (the Schema.Opaque hunk in unstable/cluster/Envelope.ts fails), so Effect's cluster/Optic/Config code is in my build and may be outside your intended profile. Worth confirming whether --version still passes for you, and refreshing that patch.

Not caused by this PR

source_graph_export_regressions fails 2 tests (imported_class_return_types_pull_in_transitive_dispatch_metadata, cross_module_arrow_callback_dispatch_is_resolved_once_and_fails_closed) — I confirmed both fail identically on merge-base 07dee0fd29. This PR takes that suite from 14 to 19 passing.

Pre-register non-native Node built-in imports.

is_node_builtin_module includes built-ins that are not is_native_module, such as node:timers/promises and node:stream/promises. This condition leaves their bindings unregistered until the normal declaration pass. An expression before such an import declaration then lowers without its hoisted import metadata. Register these built-ins during the pre-pass, with the metadata required for early references.

Splitting property_get.rs moved guarded_declared_class_get_candidate into
property_get/helpers.rs. The local-binding type-proof allowlist is keyed by
(path, function), so the entry went stale and the read became unclassified.
Same classification and rationale, new path.

Claude-Session: https://claude.ai/code/session_01P3bPE5eJQT4vQ6wf8P9JDN
`Object.setPrototypeOf(Ctor, obj)` on a declared class recorded `obj` in
CLASS_PROTOTYPE_OBJECTS. That table means "the object INSTANCES of this
class inherit from", and the instance-side field-read and method-dispatch
walks read it for exactly that purpose, so a constructor-side link leaked
onto instances:

    const schema = { ast: "STATIC-ONLY", greet() { return "static-only" } }
    class Opaque {}
    Object.setPrototypeOf(Opaque, schema)
    new Opaque().ast      // "STATIC-ONLY", Node says undefined
    new Opaque().greet()  // ran, Node throws TypeError

Prototype-method mirroring writes through the same table, so
`Opaque.prototype.added = fn` also made `added` an own enumerable key of
the user's `schema` object.

Give the constructor link its own GC-rooted table, CLASS_STATIC_PROTOTYPES,
read only by the static-side lookups: the ClassRef arm of
js_object_get_field_by_name, the generic `in` presence walk,
js_class_static_method_call, and Object.getPrototypeOf. It is visited by
both the full and budgeted class-side-table root walks (new
ClassSideTableRootSlot::StaticPrototype), and the store fires the root
write barrier, matching CLASS_DECL_PROTOTYPE_OBJECTS beside it.

This also closes two gaps the original arm left open:

- `Ctor.staticMethod()` written directly on the class ref threw "is not a
  function" (it only worked through an any-typed alias, which takes
  dynamic dispatch). js_class_static_method_call now walks the recorded
  constructor prototypes with `this` bound to the receiver.
- `Object.getPrototypeOf(Ctor)` ignored the link entirely. It now returns
  the recorded object, and CLASS_STATIC_PROTOTYPE_NULLED distinguishes
  "never linked" (default Function.prototype) from an explicit
  `setPrototypeOf(Ctor, null)` (null), which Node separates.

Regression tests assert Node's exact output for both sides — including
that instances see nothing and that the user's object is not mutated,
which the original test did not cover.

Clear CLASS_STATIC_PROTOTYPE_NULLED with the other class-side tables.

This helper clears CLASS_STATIC_PROTOTYPES but retains explicit-null markers. A later test can reuse the class id and observe null from a prior test. Reset CLASS_STATIC_PROTOTYPE_NULLED in this helper.

Root static_proto before allocating key.

Line 1598 can collect after class_static_prototype returns a movable raw pointer. The GC forwards the side-table entry, but it cannot update local static_proto. Line 1599 can then dereference pre-move memory and crash. Use RuntimeHandleScope to root static_proto before creating key. Root key through the property lookup too.

1598, In the code around class_static_prototype, root static_proto with
RuntimeHandleScope before allocating key, then root key for the property lookup
as well. Ensure both handles remain rooted across allocations and use the rooted
references for subsequent dereferences and lookup.

Continue static inheritance after deleting a child static property.

When class_is_key_deleted(class_id, name) is true, get_field_by_name.rs returns undefined before checking class_static_prototype. has_property.rs also discards inherited_data inside the deletion guard. Both paths hide inherited static properties after deletion.

Skip the deleted own entry, then continue static-prototype and parent traversal.

Canonicalize the ClassRef ID before storage.

class_static_prototype() canonicalizes specialized IDs before lookup, but class_static_prototype_root_store() stores the raw ID. A generic specialization can therefore store a prototype that Object.getPrototypeOf() and static-property lookup cannot retrieve. Canonicalize the ID before insertion.

Update class_static_prototype_root_store() to canonicalize the ClassRef ID
before inserting the prototype, matching the normalization performed by
class_static_prototype(); preserve the existing storage behavior after
canonicalization so generic specializations are retrievable through prototype
and static-property lookups.
