[VD:abstract] problem of detect MIME-Type as 'unknown' with the zero size file

Hey guys, i recently install elFinder with the original php connector and configure it as the wiki saying.
When i visit the root path, it seems work, and get the following page and http response .

But i cant edit the txt file, i.e. a.yml.
Following is my configuration and file permission.

$opts = array(
        // 'debug' => true,
        'roots' => array(
                // Items volume
                array(
                        'driver'        => 'LocalFileSystem',           // driver for accessing file system (REQUIRED)
                        //'path'          => '../files/',                 // path to files (REQUIRED)
                        'path'          => '/etc/ansible/roles',                 // path to files (REQUIRED)
                        //'URL'           => dirname($_SERVER['PHP_SELF']) . '/../files/', // URL to files (REQUIRED)
                        'URL'           => '/etc/ansible/roles' . '/../files/', // URL to files (REQUIRED)
                        'trashHash'     => 't1_Lw',                     // elFinder's hash of trash folder
                        'winHashFix'    => DIRECTORY_SEPARATOR !== '/', // to make hash same to Linux one on windows too
                        //'uploadDeny'    => array('all'),                // All Mimetypes not allowed to upload
                        'uploadDeny'    => array(),                // All Mimetypes not allowed to upload
                        //'uploadAllow'   => array('image', 'text/plain'),// Mimetype `image` and `text/plain` allowed to upload
                        'uploadAllow'   => array('all'),         // Mimetype `image` and `text/plain` allowed to upload
                        // 'uploadOrder'   => array('deny', 'allow'),      // allowed Mimetype `image` and `text/plain` only
                        'uploadOrder'   => array('allow', 'deny'),      // allowed Mimetype `image` and `text/plain` only
                         'accessControl' => 'access',                     // disable and hide dot starting files (OPTIONAL)
                        'attributes'    => array(
                               array(
                                     'pattern' => '.yml',
                                     'read' => true,
                                     'write' => true,
                                     'locked' => true,
                               )
                        )
                ),
// Trash volume
                array(
                        'id'            => '1',
                        'driver'        => 'Trash',
                        'path'          => '../files/.trash/',
                        'tmbURL'        => dirname($_SERVER['PHP_SELF']) . '/../files/.trash/.tmb/',
                        'winHashFix'    => DIRECTORY_SEPARATOR !== '/', // to make hash same to Linux one on windows too
                        'uploadDeny'    => array('all'),                // Recomend the same settings as the original volume that uses the trash
                        'uploadAllow'   => array('image', 'text/plain'),// Same as above
                        'uploadOrder'   => array('deny', 'allow'),      // Same as above
                        'accessControl' => 'access',                    // Same as above
                )
        )
);

ls -l /etc/ansible/roles/a.yml
-rw-r--r-- 1 root root 0 Jan 8 02:35 /etc/ansible/roles/a.yml

@haozhaodev The elFinder php connector sets the MIME type to "unknown" if the MIME type of the extension is unknown and the file size is zero. This is a problem when creating a text file so I will fix this.

Thanks! 👍
