Executable builds require a platform linker driver and SDK. On macOS 15+ arm64, LLVM-tier executables use the matching optional helper and precompiled runtime pack, so the driver only links; explicit C builds, LLVM fallbacks, and `--sanitize` still compile C. `--emit=ir|c|llvm` requires only Node, while `--emit=asm|obj` requires neither an external compiler nor a linker. Builds use a bounded persistent cache by default. Exact unchanged library builds validate their recorded TypeScript/module-resolution inputs and restore the generated C/LLVM unit before starting the frontend. TypeScript comment-only edits can restore validated lowered IR instead, rebasing source locations and regenerating exact-source build identity before emission; directives, JSDoc-bearing JavaScript, token edits, configuration, package resolution, and newly appearing candidates still invalidate it. Library identity getters live in a tiny C translation unit, so build-id-only changes reuse the large compiled program object and compile only that small member before rearchiving. The native cache then applies its independent toolchain checks. Unchanged executables and library archives skip native code generation and linking after fresh compiler metadata probes, while edited builds reuse stable runtime objects. Experimental provenance-source builds bypass the early frontend tier because their fetched-source registry is process state. FFI builds with archive/object inputs or ambient `system_libraries` relink every time but still reuse runtime objects. Mutable compiler input paths such as `CPATH` and `SDKROOT`, and compiler wrappers, bypass persistent native artifacts and objects so same-path dependency edits cannot go stale. Opaque archiver wrappers rebuild library program members and archives while retaining runtime-object reuse. Direct Clang, Apple's system Clang shim, `zig cc`, trusted platform archivers, and `zig ar` retain their applicable persistent tiers. Set `SCRIPTC_NO_CACHE=1` to bypass every cache or `SCRIPTC_CACHE_DIR` to choose its location; an existing POSIX override must already be private, otherwise caching is bypassed without changing its permissions. diff --git a/packages/cli/scripts/runtime-pack-host.d.mts b/packages/cli/scripts/runtime-pack-host.d.mts new file mode 100644 index 000000000..1a7b53d29 --- /dev/null +++ b/packages/cli/scripts/runtime-pack-host.d.mts @@ -0,0 +1,5 @@ +export function hostSupportsRuntimePack( + platform?: NodeJS.Platform, + architecture?: string, + hostRelease?: string, +): boolean; diff --git a/packages/cli/scripts/runtime-pack-host.mjs b/packages/cli/scripts/runtime-pack-host.mjs new file mode 100644 index 000000000..dc18cfdc0 --- /dev/null +++ b/packages/cli/scripts/runtime-pack-host.mjs @@ -0,0 +1,10 @@ +import { release } from "node:os"; + +export function hostSupportsRuntimePack( + platform = process.platform, + architecture = process.arch, + hostRelease = release(), +) { + const darwinMajor = Number.parseInt(hostRelease.split(".", 1)[0] ??

Builds use a bounded persistent cache by default. Exact unchanged library builds validate their recorded TypeScript/module-resolution inputs and restore the generated C/LLVM unit before starting the frontend. TypeScript comment-only edits can restore validated lowered IR instead, rebasing source locations and regenerating exact-source build identity before emission; directives, JSDoc-bearing JavaScript, token edits, configuration, package resolution, and newly appearing candidates still invalidate it. Library identity getters live in a tiny C translation unit, so build-id-only changes reuse the large compiled program object and compile only that small member before rearchiving. The native cache then applies its independent toolchain checks. Unchanged executables and library archives skip native code generation and linking after fresh compiler metadata probes, while edited builds reuse stable runtime objects. Experimental provenance-source builds bypass the early frontend tier because their fetched-source registry is process state. FFI builds with archive/object inputs or ambient `system_libraries` relink every time but still reuse runtime objects. Mutable compiler input paths such as `CPATH` and `SDKROOT`, and compiler wrappers, bypass persistent native artifacts and objects so same-path dependency edits cannot go stale. Opaque archiver wrappers rebuild library program members and archives while retaining runtime-object reuse. Direct Clang, Apple's system Clang shim, `zig cc`, trusted platform archivers, and `zig ar` retain their applicable persistent tiers. Set `SCRIPTC_NO_CACHE=1` to bypass every cache or `SCRIPTC_CACHE_DIR` to choose its location; an existing POSIX override must already be private, otherwise caching is bypassed without changing its permissions. diff --git a/packages/cli/src/bootstrap.ts b/packages/cli/src/bootstrap.ts index 5daf7d8b4..3904d65ef 100644 --- a/packages/cli/src/bootstrap.ts +++ b/packages/cli/src/bootstrap.ts @@ -8,6 +8,7 @@ import { basename, dirname, join, resolve } from "node:path"; import { fileURLToPath } from "node:url"; import { parseArgs } from "node:util"; import { hostSupportsRuntimePack } from "../scripts/runtime-pack-host.mjs"; +import { LEGACY_C_EXECUTABLE_WARNING, shouldWarnLegacyCExecutable } from "./legacy-c-warning.js"; import { CLI_OPTIONS, USAGE } from "./usage.js"; // Node 24 can persist V8's compiled module bytecode. scriptc's CLI imports @@ -79,14 +80,13 @@ async function tryFastPath(): Promise { } let startup: typeof import("@scriptc/compiler/startup-cache"); - let driver: ReturnType; + let buildPlatform: string; try { startup = await import("@scriptc/compiler/startup-cache"); - driver = startup.resolveCc(); + buildPlatform = startup.targetPlatform(startup.resolveCc()); } catch { return null; } - const buildPlatform = startup.targetPlatform(driver); if (command === "run" && buildPlatform === "wasi") return null; const input = resolve(inputArg); const outDir = values.out ? dirname(resolve(values.out)) : join(dirname(input), ".scriptc"); @@ -101,7 +101,20 @@ async function tryFastPath(): Promise { const ffiBytes = ffiPath === null ? null : await readFile(ffiPath).catch(() => null); if (ffiPath !== null && ffiBytes === null) return null; const root = await startup.prepareBuildCacheRoot(startup.resolveBuildCacheRoot()); - const nativeEnvironment = await startup.executableNativeEnvironmentFingerprint().catch(() => null); + const helperObjectRoute = hostSupportsRuntimePack(process.platform, arch) && + (process.env["SCRIPTC_TARGET"] ??

The runtime's FFI slice + (`scr_ffi.c`) is a C-ABI surface for the COMPILED program's own + declarations — it never `dlopen`s arbitrary `.node` files, and the + frontend deliberately fences dynamic module graphs (a compiled + binary's module graph is fixed at build). +3. **Module-graph timing.** `pg` probes `pg-native` lazily on + `pg.native` first access. In a compiled binary the npm-static graph + is resolved at build; a `require('pg-native')` that nothing can + satisfy must not be silently dropped — the honest answer is the + SC2030-family diagnostic (unresolvable import → named fence), not a + runtime trap. + +## The fallback (and why it is faithful) + +`pg-native` is a pure ACCELERATOR: synchronous libpq bindings behind +`Client`'s optional `native` mode. Plain `pg` (the JS protocol client, +TCP or Unix socket) is the default for every Node program that never +opts in, and it is the runtime's supported surface: the compiled +program drives the same wire protocol (`Query`, `Bind`, TLS via the +vendored mbedTLS stack) over the runtime's socket slice. Programs that +need `pg` compile with the JS client and no source changes — `pg.native` +accesses are the one fenced shape, reported at build with a named +diagnostic instead of a broken binary. + +## What would change this + +A static `libpq` could in principle be vendored and linked the way +mbedTLS is (C ABI, no host needed), with a `scr_pg_*` raw slice in the +runtime. That is a deliberate vendor-onboarding decision (license, +build matrix, security surface), not a `.node` shim — `dlopen` of +N-API addons remains impossible without embedding a Node host.
