File has no permission entries, del returns exit code 0 / success

[mspace]

I'm using del to delete file like this (and in some cases directories *.css)

gulp.task("delete", function(cb) {
  del(["./deleteMe.txt"]).then(function (paths) { // returns a promise; https://github.com/sindresorhus/del
    console.log("Deleted files and folders: \n", paths.join('\n'));
    cb();
  }, function (reason) {
    cb("Failed to delete files " + reason);
  });
});

[08:55:51] Using gulpfile X:\Gulpfile.js
[08:55:51] Starting 'delete'...
[08:55:51] Finished 'delete' after 3.82 ms
Process terminated with code 0.
Deleted files and folders:

If the same task uses nodejs's fs it works, it reports error correctly:

fs.unlink("deleteMe.txt", function (reason) {
    console.log("Reason " + reason);
  });

Reason Error: EPERM: operation not permitted, unlink 'X:\deleteMe.txt'

deleteMe.txt permissions:

Try returning the promise in the gulp task

gulp.task("delete", function() {
  return del(["./deleteMe.txt"]).then(function (paths) { // returns a promise; https://github.com/sindresorhus/del
    console.log("Deleted files and folders: \n", paths.join('\n'));
    cb();
  }, function (reason) {
    cb("Failed to delete files " + reason);
  });
});

In your case callback must be provided as a function argument (ReferenceError: cb is not defined). Actually I forgot to add cb parameter to function, thank you for notice. Still output is the same, no error. I believe there are two ways:

gulp.task("delete", function() {
  return del(["./deleteMe.txt"]
});

or with a callback

gulp.task("delete", function(cb) {
  del(["./deleteMe.txt"]).then(function (paths) {
    cb(); // ok
  }, function (reason) {
    cb("Failed to delete files " + reason); // fail
  });
});

Oh, didn't notice the cb. A gulp task can handle a promise so your first example should work and should return an error.

Tested on Mac OSX

'use strict';

const gulp = require('gulp');
const del = require('del');

gulp.task('delete', () => {
    return del('./deleteMe.txt');
});

output

[09:35:24] Starting 'delete'...
[09:35:24] 'delete' errored after 8.21 ms
[09:35:24] Error: EPERM: operation not permitted, unlink '/Users/sam/Projects/playground/gulp-test/deleteMe.txt'

Tested your code, but on Windows 10 still no error.

[09:41:02] Using gulpfile X:\Gulpfile.js
[09:41:03] Starting 'delete'...
[09:41:03] Finished 'delete' after 5.92 ms
Process terminated with code 0.

I'm using "del": "2.2.0" and "gulp": "3.9.0",

@mspace Does del delete your "./deleteMe.txt"? – at least on Linux it is possible to delete a file w/o permissions; you only need the permission of the folder…

[mspace]

@schnittstabil No, file stays on the filesystem. It does not get deleted. Permissions on the folder are set ok: full control modify, read & execute, list folder contents, read, write for currently logged-in user in this case me and some other users Administrators, ....

Thanks for reporting it, it's a glob issue: isaacs/node-glob/issues/245

I can also confirm this issue on Windows 10 64-bit with node 5.5.0 and npm 3.3.12. No matter what I do I cannot delete even the simplest directory with something like:

gulp.task('clean:docs', function () {
  return del([
    // here we use a globbing pattern to match everything inside the `docs` folder
    './docs/**/*'
  ]);
});

[schnittstabil]

@datatypevoid

even the simplest directory

That seems not related to this issue, you may try:

gulp.task('clean:docs', function () {
  console.log('current directory:', require('process').cwd());
  console.log('files:', globby.sync(['./docs/**/*']));
  return del(['./docs/**/*']);
});

Sorry I was still recovering this morning when I wrote that, and I must admit I was half-reading the thread trying to get in the door. When I use that function, I get:

current directory: f:\sites\project-name-here
files: []

but the files and directories remain unaffected.

[schnittstabil]

@datatypevoid If f:\sites\project-name-here\docs exists, then it looks like a globby issue (del uses globby). Please open a new issue there.

Sorry for my ignorance man. Thanks for your help though!

Closing as isaacs/node-glob#245 was fixed.
