    Details

      Description

      Steps to reproduce:

      1. Prepare a test eZ Publish 5.4 installation, fully updated to the latest sub-version (currently 5.4.7) and set up in DFS cluster mode;
      2. On the admin siteaccess, create a test image in media library e.g. "/Media/Images/mountain.png";
      3. Create an article that uses that image, with a "medium" image alias;
      4. The 'ezdfsfile' table will now have these entries for that image:

      SELECT * FROM ezdfsfile WHERE name LIKE '%mountain.%';

      5. If the corresponding 'ezdfsfile' entry for the "medium" alias is expired i.e. 'ezdfsfile.expired' = 1, refreshing the frontend article that contains the image will unexpire it;
      6. However, if the main image (in this case, "mountain.png.png") is also expired, that will no longer work, and it becomes impossible to unexpire the alias by refreshing the page;

      SELECT * FROM ezdfsfile WHERE name LIKE '%mountain.%';

      7. If you access the image directly in the URL, like this:

      http://example.com/var/ezdemo_site/storage/images/media/images/mountain.png/690-1-eng-GB/mountain.png_medium.png

      ...an HTTP 500 error will be displayed, and this error will be generated in the symfony log:

      CRITICAL - Uncaught PHP Exception Symfony\Component\Debug\Exception\FatalErrorException: "Error: Call to a member function getTimestamp() on a non-object" at /var/www/54ezdemodfs.com/vendor/ezsystems/ezpublish-kernel/eZ/Bundle/EzPublishIOBundle/BinaryStreamResponse.php line 102 
      

      Note: all image aliases exist in the file system.
