fix: compile large TypeScript source graphs natively - #8383
Conversation
📝 WalkthroughWalkthroughThe compiler now supports larger TypeScript and JavaScript source graphs with expanded export and namespace resolution, file-loader and WASM assets, native-addon routing, Windows embedding, class provenance tracking, and wider namespace calls. ChangesCompiler pipeline
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The PR substantially changes native source-graph compilation, export linking, runtime closure calls, asset handling, and object generation. Unresolved issues can produce link failures, runtime instability, broken file-loader imports, or overwritten build artifacts, so the PR is not merge-ready until the concrete correctness risks are fixed or explicitly accepted.

Confirm that an inline export const still produces a getter.
exported_var_names now only contains locals that appear in an Export::Named entry. Two consequences follow if HIR does not record an Export::Named { local, exported } for a plain inline export const foo = {...}:
- Line 377 no longer globalizes
foo, so no@perry_global_<prefix>__<id>is emitted for it. public_namesat lines 441-450 is empty, so thefor public_name in public_namesloop body never runs and noperry_fn_<prefix>__foogetter is emitted.
A consumer that imports foo then references an undefined getter symbol and the link fails. The narrowing itself is correct for renames, because exported_objects carries both sides of export { $i as filesFilter }. The open question is only whether the inline declaration shape is still covered.
Run the following script to check how HIR lowers an inline export const:
#!/bin/bash
# Description: Determine whether inline `export const` pushes an Export::Named entry alongside exported_objects.
set -uo pipefail
# Test: Find every site that populates exported_objects. Expect a paired Export::Named push.
rg -n --type=rust -C8 'exported_objects\s*\.\s*push' crates/perry-hir/src
# Test: Find every site that pushes Export::Named. Expect one covering variable declarations.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Two producers of a native module namespace disagree on the specifier spelling. Both sites call nm_install_symbol and js_create_native_module_namespace, but only one strips the node: prefix first. For export * as P from "node:path" one path requests "path" and the other requests "node:path", so the installer lookup and the runtime namespace lookup can resolve differently for the same export.
crates/perry-codegen/src/codegen/native_namespace_exports.rs#L28-L49: reuse the already-computed stripped name foradd_string_constant,nm_install_symbol, and thejs_create_native_module_namespaceargument instead of the rawsource.crates/perry-codegen/src/codegen/helpers.rs#L1625-L1639: keep the stripping behavior, and share one normalization helper with the getter emitter so the two producers cannot drift again.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Sanitize the export name before using it in the LLVM symbol.
name is a JavaScript identifier and is interpolated verbatim into an LLVM global identifier. Every sibling getter producer sanitizes first: crates/perry-codegen/src/codegen/module_globals_emit.rs (line 463) uses sanitize(public_name), and crates/perry-codegen/src/codegen/artifacts.rs (line 789) uses sanitize(exported_name). For an alias such as export * as $ns from "node:path", the raw spelling produces a symbol that no consumer constructs the same way, and characters outside [A-Za-z0-9_] are not valid in an LLVM identifier.
Emit the sanitized name as the canonical getter. If the raw spelling is also needed, mirror the pattern in artifacts.rs (lines 984-1011) and add a raw-name alias that forwards to it.

Correct the stale ForeignFunction wrapper documentation in both codegen locations. The documented __perry_wrap_extern_* thunk is not emitted; re-export lowering declares the source module's __perry_wrap_perry_fn_<source_prefix>__<source_local> closure wrapper and passes it to js_closure_alloc_singleton. Update the comments to describe the current symbol family and avoid referring maintainers to a nonexistent generated thunk.

Make NoLinkDestination::artifact_path collision-resistant for distinct module
names that produce the same native_object_file_stem, such as path separators
versus hyphens. Add a deterministic unique component derived from the original
module identity, or detect and reject duplicate destinations before parallel
writes begin; preserve the existing no-link artifact output behavior otherwise.

Summary
Compile large real-world TypeScript source graphs natively instead of feeding Perry a bundled/minified artifact. The motivating OpenCode source graph now completes on Windows with all 4,743 discovered modules native-compiled and zero JavaScript fallback modules.
Changes
export *barrels, nested namespaces, class aliases, and declared functions so large package graphs link to their defining symbols.__exportshapes, high-arity/rest namespace calls, and Windows COFF asset/link ordering.Related issue

Real OpenCode validation (
packages/opencode/src/index.ts, OpenCode commitd041eee):AB1A68AF5F12E4EAB6D337B9A472D9F4CD41DA4980A1AB18DEBC1D900BA23D58The remaining inventory is dependency/runtime work rather than TypeScript parse blockers: four unresolved optional/generated/platform imports (
msgpackr-extract, Axios' Node distribution subpath, generatedopencode-web-ui.gen.ts, andbun:sqlite), 19 native-addon package exclusions, 25 compatibility shims, plus package-version/browser-global/generic-constraint warnings. Runtime feature smoke testing remains follow-up work. Archive strip/dedup is also the largest remaining compile-time hotspot at roughly 19 minutes; the linked binary is about 1.62 GiB.Checklist
