lib: add `internalUtil.kEmptyObject` #43159

LiviaMedeiros · 2022-05-20T16:52:00Z

Problem

There are lots of places in core where we have to pass an optional "pre-ES6 map"-style object with optional properties.

To avoid verbose boilerplate code or overusing of optional chaining, and to allow destructuring, we need a fallback value of {}, thus creating a throwaway object:

function fn({ foo = 'defaultFoo', bar } = {}) { // still unsafe
}
function fn(options = {}) {
  let foo = 'defaultFoo';
  if (options != null) // still have to check or validate
    foo = options.foo ?? 'defaultFoo';
  const bar = options?.bar;
 }
function fn(options) {
  options ??= {};
  const foo = options.foo || 'defaultFoo';
  const { bar } = options;
}
function fn(options) {
  const { foo = 'defaultFoo`, bar } = options ?? {};
}

It is also highly affected by prototype tampering, e.g.

import tls from 'node:tls';
Object.assign(Object.prototype,{rejectUnauthorized:!1,ca:'pwned',passphrase:'gwak'});
console.log((new tls.Server).ca);
console.log(tls.createServer().passphrase);

So we have to prefer Object.create(null), which is slower and still creates a throwaway object on every usage.

Solution

export const kEmptyObject = Object.freeze(Object.create(null));

const { foo, bar } = options ?? kEmptyObject;

A single immutable object that guarantees any property to be undefined.

What if our own code later assigns to a defaulted-to nullObject? It won't throw and the assignment will be lost. Do we enforce not modifying parameters through lint rules? Should we when nullObject was used?

LiviaMedeiros · 2022-05-20T17:03:44Z

It won't throw and the assignment will be lost.

I believe assignment to a frozen object throws in strict mode? Are there places where it doesn't? Of course this object is not supposed to be exposed to usedland in any way, nor used in any scenario where there is a slightest chance to mutate it.

I only tried with likewise constructed null object in REPL.

It throws for me in REPL as well:

Welcome to Node.js v18.1.0.
Type ".help" for more information.
> Object.assign(Object.freeze(Object.create(null)), { blep: 'blop' });
Uncaught TypeError: Cannot add property blep, object is not extensible

Maybe it should be named kEmptyObject instead?

Sure, renamed.

I'm still tracing some tangled places in http*, will rebase to ensure alphabetic order of imports right after that.

Trying a simpler approach, one that could be more likely used.

> o=Object.freeze(Object.create(null))
[Object: null prototype] {}
> o.foo = 'bar'
'bar'
> o.foo
undefined

Right, it doesn't run in strict mode by default. 😅

$ node --use_strict

Both approaches are covered by test:

Thank you for your diligence. I've learned something ;)

I highly suspect this will cause major performance regressions as frozen objects are slower than their traditional counterparts.

This should be deeply investigated for regressions before landing.

I highly suspect this will cause major performance regressions as frozen objects are slower than their traditional counterparts.

AFAIK performance hit from freezing was a thing in the past, but in modern v8 there's no difference anymore.

Synthetic testing on 18.1.0 and master shows [fastest] {} < frozenEmptyObject ≈ regularEmptyObject < Object.create(null) < { __proto__: null } [slowest] for me.

To be safe, it would make sense to not backport this.

This should be deeply investigated for regressions before landing.

Aside from benchmark CI runs in Jenkins, what kind of investigation would you recommend?

Be aware that when doing many comparisons the risk of a false-positive
result increases. In this case, there are 841 comparisons, you can thus
expect the following amount of false-positive results:
  42.05 false positives, when considering a   5% risk acceptance (*, **, ***),
  8.41 false positives, when considering a   1% risk acceptance (**, ***),
  0.84 false positives, when considering a 0.1% risk acceptance (***)

AFAIK performance hit from freezing was a thing in the past, but in modern v8 there's no difference anymore.

Amazing progress, I might have missed it. Have you got a link?

Amazing progress, I might have missed it. Have you got a link?

Not 100% sure if these are exhaustive or there were follow-ups:
https://codereview.chromium.org/135903014 / https://bugs.chromium.org/p/v8/issues/detail?id=1858 (Obect.freeze)
https://codereview.chromium.org/776143005 / https://bugs.chromium.org/p/v8/issues/detail?id=3662 (Object.seal, Object.preventExtensions)

(for my tests I ran destructuring, not iterating)

Edit: according to https://bugs.chromium.org/p/chromium/issues/detail?id=980227, there still are issues with some particular operations.

I tried to benchmark their 1000-element array in Chromium and got this (higher is better):

[ ...frozenArray ] - 2_354_212 ops/s
[ ...array ] - 2_229_525 ops/s
frozenArray.slice() - 13_790 ops/s
array.slice() - 2_228_496 ops/s

But these operations shouldn't be applicable to this partucular empty object.
