[22 regression] Breaks gulp with Cannot assign to read only property 'atime' of object '#<Stats>'

Version

v22.0.0

Platform

Linux

Subsystem

fs

What steps will reproduce the bug?

"use strict";
var fs = require("fs");
var stat = fs.statSync("./package.json")
stat.atime;
stat.atime = 2;

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

It should set stat.atime to 2

What do you see instead?

stat.atime = 2;
           ^

Additional information

Original bug report: gulpjs/vinyl-fs#350

Caused by #50908

I'm opening a PR

Is there a workaround for this with Gulp? I would ask over in

NodeJS 22 breaks vinyl-js gulpjs/vinyl-fs#350

but GitHub blocks me from commenting there (permissions of that repo allow certain people to comment only?).

I found a workaround for my case (but its common case, so maybe it helps someone):

I didn't realize new versions of Node.js include recursive and filter options in various fs functions including cp. So I was able to delete gulp and rewrite this gulpfile.js,

const {src, dest, series} = require('gulp')
const {promises} = require('fs')

async function mkDist() {
	try { await promises.mkdir('./dist') } catch (e) { if (e.code !== 'EEXIST') throw e }
}

function copy() {
	return src([ './src/**', '!./src/**/*.{ts,tsx}', './src/**/*.d.ts', ]).pipe(dest('./dist/'))
}

exports.copyAssets = series(mkDist, copy)

to a plain Node.js script using the relatively new cp function with recursive and filter options:

import fs from 'fs'

async function mkDist() {
	try { await fs.promises.mkdir('./dist') } catch (e) { if (e.code !== 'EEXIST') throw e }
}

await fs.promises.cp('./src', './dist', {
	recursive: true,
	filter: (src) => src.endsWith('.tsx') || (src.endsWith('.ts') && !src.endsWith('.d.ts')) ? false : true
})

Not bad! It used to be tedious to this sort of thing with plain Node prior to cp+recursive+filter, which I'm sure is why libraries like gulp/vinyl came to exist.

replace gulp with plain Node fs.cp to avoid gulp/vinyl breakage by No…

Looks like node v22 breaks stuff with Gulp
