Only some files are being copied, if run inside a series

[ghnp5]

What were you expecting to happen?

All 840 files should be copied, recursively.

What actually happened?

Only the first few files (sorted alphabetically) of each folder are being copied, instead of all files.

This used to work, but seems broken since v5.

This is happening as the last step of a gulp.series, consistently. But if I run npx gulp copy-changed, it copies all the files, always.

Please give us a sample of your gulpfile

import { spawnSync } from 'child_process';
import glob from 'glob';
import path from 'path';
import fs from 'fs';
import mergeStream from 'ordered-read-streams';
import PluginError from 'plugin-error';
import gulp from 'gulp';
import htmlmin from 'gulp-htmlmin';
import clean from 'gulp-clean';
import newer from 'gulp-newer';
import changed from 'gulp-changed';
import rename from 'gulp-rename';
import { fileURLToPath } from 'url';

const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);
console.log('__filename:', __filename);
console.log('__dirname:', __dirname);

(...)

// npx gulp copy-changed
gulp.task('copy-changed', () => {
	return gulp.src([path.join(__dirname, 'build\\_delta\\**\\*')], { dot: true })
		.pipe(gulp.dest(path.join(__dirname, 'build\\')));
});

gulp.task('build-debug', gulp.series(
	...,
	...,
	...,
	'copy-changed'
));

The previous task copies stuff to that "_delta" folder, inside a mergeStream (which used to be on merge-stream, but when I was trying to fix this issue, I had upgraded to ordered-read-streams, but the same happens).

Seems that what's happening is that at the time "copy-changed" runs, the files aren't ready yet or so.

If I put a "sleep" of 3 seconds, it seems to work now.

const sleep = (ms) => new Promise(resolve => setTimeout(resolve, ms));

gulp.task('copy-changed', () => {
	return sleep(3000).then(() => {
		return gulp.src([path.join(__dirname, 'build\\_delta\\**\\*')], { dot: true })
		.pipe(gulp.dest(path.join(__dirname, 'build\\')));
	});
});

This used to work before, so I'm not sure why it needs a sleep now.

Please try v8.0.3 - I believe this is the same problem as #135 but you are in the best position to test it out.

If I don't here back in a little while, I will close this as a duplicate of #135

Thanks very much. I've since moved to another solution since I couldn't keep the instability of Gulp (sorry about that!).

If no one else is complaining, or this is a duplicate, then I'm happy to close this issue.

Thanks for looking and for fixing! 👌🏻

It's no problem. Gulp v4 has been stable for almost 10 years and v5 was an explicit departure from some of the norms and expectations.
