Hi Everyone,
Today my RoundCube suddenly undeliverable attachments.
when I upload to send an error occurred in <$ RoundCube> / logs / errors:
file_get_contents(): Filename cannot be empty in /var/www/roundcubemail-1.1.2/plugins/redundant_attachments/redundant_attachments.php on line 104.
Thanks for any advices.

				Make sure your temp directories are writable.
			
			
			
				Hi SKaero,
Thanks for your advice,
I confirmed then i saw "tempname" of uploaded files was created, but them size = 0.

				Does it work if you disable the redundant_attachments plugin?
			
			
			
				After disable the 'redundant_attachments' plugin
it didn't work (create size=0 file) 
and roundcube client display error dialog with following message: 
     [File upload failed.]

NgMDat.
			
			
			
				Are there any errors in the web server log? Do you a space quota that has been exceeded?
			
			
			
				Thanks for your response.
There are no error in web-server log and have a lot of disk space for my centos box.
After executing "yum update" I think that something affected to roundcube but i don't know what and where.

				Hi Everyone,
After tracing roundcube upload process, i know that following code was reason of issue.
It take a lot time to find out.
Is it bug or special function ?
  
    <$ROUNDCUBE>/plugins/database_attachments/database_attachments.php
    /**
     * Save a newly uploaded attachment
     */
    function upload($args)
    {
        $args['status'] = false;
        ...
        if ($status) {
            $args['id']     = $key;
            $args['status'] = true;
            $args['path']   = null;       <---- it clear the path of temp file uploaded from client.
        }
        return $args;
    }
			
			
			
				It should do that since at that point the attachment should be cached in the database.
			
			
			
				Hi SKaero,
Thanks for your comment.
If I disable that line, roundcube will send mail with attachments as expected.
      ...
      if ($status) {
            $args['id']     = $key;
            $args['status'] = true;
            // $args['path']   = null;       <---- disable this line.
      }
      ...
Something's wrong with that way to resolve this issue, isn't it ?

				Do you have both the redundant_attachments and database_attachments plugins enabled?
			
			
			
				Yes, with default configuration, i have both of them enabled..
			
			
			
				I think that maybe your problem, redundant_attachments stores in both the file system and the database, database_attachments just stores in the database. If database_attachments has already handled the attachment then its not available for the redundant_attachments plugin.
			
			
			
				Thanks for your advice,
when i disable database_attachments plugin, roundcube work fine.
I like to close this issue.
Thanks your time and dedication.

NgMDat.
