[Kolab-devel] DAVException in iRony-0.2.7

[Daniel Morlock]

Hi,

I backtraced the problem a bit: For the calendar listing, the method 
CalendarBackend::_read_calendars() is invoked. In this method, each 
folder gets its uid i.e. using $id = DAVBackend::get_uid($folder) as 
follows:

     /**
      * Helper method to extract folder UID metadata
      *
      * @param object \kolab_storage_folder Folder to get UID for
      * @return string Folder's UID
      */
     public static function get_uid($folder)
     {
         // UID is defined in folder METADATA
         $metakeys = array(self::IMAP_UID_KEY, 
self::IMAP_UID_KEY_PRIVATE, self::IMAP_UID_KEY_CYRUS);
         $metadata = $folder->get_metadata($metakeys);
         foreach ($metakeys as $key) {
             if (($uid = $metadata[$key])) {
                 return $uid;
             }
         }

         // generate a folder UID and set it to IMAP
         $uid = rtrim(chunk_split(md5($folder->name . 
$folder->get_owner() . uniqid('-', true)), 12, '-'), '-');
         self::set_uid($folder, $uid);

         return $uid;
     }

For unkown reason, the $uid cannot be retrieved from the metadata and 
the method generates a new $uid and tries to set it to IMAP using 
self::set_uid():

     /**
      * Helper method to set an UID value to the given IMAP folder 
instance
      *
      * @param object \kolab_storage_folder Folder to set UID
      * @param string Folder's UID
      * @return boolean True on succes, False on failure
      */
     public static function set_uid($folder, $uid)
     {
         if (!($success = $folder->set_metadata(array(self::IMAP_UID_KEY 
=> $uid)))) {
             $success = 
$folder->set_metadata(array(self::IMAP_UID_KEY_PRIVATE => $uid));
         }
         return $success;
     }

This method tries to set the given $uid as metadata for the given 
$folder object (which is from type "kolab_storage_folder"). But return 
value of $folder->set_metadata() is false, so the metadata was not set 
properly. This results in a temp-uid that is used when listing the 
calendars but is never stored. So when I click on this uid it doesn't 
exist anymore and result in the error stated in my first mail.


Any ideas?

Best,
Daniel.
