method chmod in WP_Filesystem doesn't work in recursive mode

[G.Hue]

The following code doesn't work when recursive mode is used :
File wp-admin\includes\class-wp-filesystem-ftpext.php
Line 142

function chmod($file, $mode = false, $recursive = false) {
		if( ! $mode )
			$mode = $this->permission;
		if( ! $mode )
			return false;
		if ( ! $this->exists($file) && ! $this->is_dir($file) )
			return false;
		if ( ! $recursive || ! $this->is_dir($file) ) {
			if ( ! function_exists('ftp_chmod') ){
				return @ftp_site($this->link, sprintf('CHMOD %o %s', $mode, $file));
			}
			echo "@ftp_chmod(_$this->link, $mode, $file);";
			return @ftp_chmod($this->link, $mode, $file);
		}
		
		//Is a directory, and we want recursive
		$filelist = $this->dirlist($file);
		foreach($filelist as $filename){
			$this->chmod($file . '/' . $filename, $mode, $recursive);
		}
		return true;
	}

No chmod is apply on the directory. Chmod is apply only on subfiles (and subdirectories but the same problem appear...)

$this->dirlist return an array of array. On this case:

$this->chmod($file . '/' . $filename, $mode, $recursive);

$filename is an array, not the filename. It can't work.

Postponing to 3.0 since we don't have a patch.

What should the settings on the directories be set to? ($mode & exec (browse) bits?)

first attempt at fixing this bug

[reaperhulk]

The attachment above is my attempt at fixing this bug. I reordered the logic so it checks to see if it's recursive and a directory first. It will then recursively call chmod (using the proper filename now).

Patch using svn diff.

[dd32]

The only problem i can see with that is that in some cases, you'll need to chmod the folder before you can get a directory listing.. That should be a pretty rare case however.

I'm going to attempt testing this shortly along with a few other changes.

(In [12997]) Fix recursive chmod for WP_Filesystem. Props reaperhulk for FtpExt. Fixes #11261

[westonruter]

In 62636:

Filesystem: Fix subdirectory recursion in WP_Filesystem_Direct::chgrp() and ::chown().

This applies the equivalent fix which had previously been done to ::chmod(). Tests are added for all three methods.

Developed in subset of ​https://github.com/WordPress/wordpress-develop/pull/11593.
Follow-up to r12997.

Fixes #65584.
See #65409, #11261.
