fix(standalone): spawn workers from embedded bundles in compiled binaries - #5761
Conversation
…ries bun build --compile flattens the main bundle into /$bunfs/root while nested worker entrypoints keep their directory structure, so new Worker(new URL(...)) dies with ModuleNotFound for every Bun Worker in the standalone ocx binary (oven-sh/bun#29124). Storage cleanup policy runs, trash restores, and Codex history sync all fail in release builds with worker_failed. Pre-bundle policy/restore/history worker entrypoints in build:standalone and spawn them from Blob URLs via a new spawnWorker helper, keeping the URL form as the source-checkout fallback. Also re-sign the compiled executable on macOS: the linker ad-hoc signature does not survive the embedded payload and the kernel kills the binary on launch, and drop --target when it equals the host, which produces the same SIGKILL.

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe standalone build now generates bundles for the policy, restore, and history workers. Worker launch sites use a shared helper that selects an embedded bundle when available and otherwise uses the development URL. The build also changes target handling and adds macOS code signing.

Extract worker filenames with a platform-aware path operation.
On Windows, join() produces backslash-separated entry paths. entry.split("/") then returns the entire path rather than policy-worker.ts. The subsequent read uses that path as a filename under workerOut, so a Windows standalone build cannot read the worker bundle. Use basename(entry, ".ts") + ".js" instead. Node’s path documentation confirms that Windows path operations produce backslash separators. (nodejs.org)
As per coding guidelines, “Preserve Linux, macOS, and Windows behavior. Do not add shell-specific assumptions to cross-platform scripts.”

Restore the worker-bundle placeholder after compilation.
scripts/build-standalone.ts:51-54 overwrites src/generated/worker-bundles.gen.ts with bundled worker sources and never restores it. src/worker-embed.ts:16-20 uses a bundled worker whenever an entry exists, so later source-checkout runs can execute stale worker code instead of the current source.
Restore the placeholder in a finally block around compilation so both successful and failed compilations leave source checkouts in development mode.

Revoke each embedded worker’s object URL.
Policy scheduling can launch workers daily or weekly in a long-lived server, and the history migration guardian can retry once per minute for up to 60 ticks. Restore and manual runs can add more launches. Each terminated worker therefore leaves its Blob-backed URL until process exit.
The existing lifecycle listener only resolves the worker’s close promise. It does not retain the URL, so add a close listener in spawnWorker. Revoke the URL if Worker construction throws.
Suggested fix
const src = WORKER_BUNDLES[key];
if (src) {
- return new Worker(URL.createObjectURL(new Blob([src], { type: "text/javascript" })));
+ const url = URL.createObjectURL(new Blob([src], { type: "text/javascript" }));

+ const worker = new Worker(url);
+ worker.addEventListener("close", () => URL.revokeObjectURL(url), { once: true });
+ return worker;

+ throw error;

}This is a real resource leak, but the available source does not establish a major availability impact. Minor severity is appropriate.

Atomically update the temporary generated module.
src/generated/worker-bundles.gen.ts is a checked-in placeholder consumed by src/worker-embed.ts. writeFileSync(GEN_FILE, ...) truncates the file before writing. If the initial write or restoreGenPlaceholder() write fails or is interrupted, the file can become invalid and later source builds or tests can fail. The cleanup block cannot repair a failed initial write or a partial cleanup write.
Use a temporary file in the same directory, rename it over GEN_FILE, and remove the temporary file on failure for both replacements. This file is temporary build input rather than final release state, but preserving a valid module prevents the build from leaving the checkout unusable.

spawnWorker falls back to the source URL when its key has no generated bundle. That is right in a source checkout and breaks only the compiled binary, so a key that drifts from build-standalone's WORKER_ENTRIES, or a new bare new Worker(new URL(...)), would pass every source-run test and ship the #5761 failure again. Pin key/file agreement both ways and list the one bare worker (the pnpm-only owner lookup) as an explicit exemption.

Summary
Standalone
ocxbinaries (release builds) cannot start any Bun Worker: the storage cleanup policy, trash restore, and Codex history units all fail withworker_failed/ModuleNotFound resolving "/$bunfs/root/<worker>.ts" (entry point).Root cause:
bun build --compileflattens the main bundle into/$bunfs/root, while nested worker entrypoints keep their directory structure, sonew Worker(new URL("./policy-worker.ts", import.meta.url).href)never resolves in a compiled binary (oven-sh/bun#29124). Source checkouts (bun run) are unaffected, which is why CI did not catch it.The fix embeds each worker entrypoint (
policy-worker,restore-worker,history-worker) as a pre-bundled source string duringbuild:standaloneand spawns it from a Blob URL through a newspawnWorkerhelper (src/worker-embed.ts), which falls back to the original URL form in source checkouts.The build script also gains two hardening fixes discovered while validating:
codesign --force --sign -on macOS: bun's linker ad-hoc signature does not survive the embedded payload, and the kernel kills the compiled executable on launch (SIGKILL) once the payload is large enough.--targetis omitted when it equals the host: passing it (even for the host triple) produces a binary the kernel kills on launch.Verification
