Cannot access files, but can access the library

[dxcore35]

Hello,

When I put my server address http://SERVER.synology.me/cops into Marvin 3 reader on iOS the app successfully find the server and show all the categories. But after choosing any category the app throw the error, that the feed cannot be downloaded. I tired to replicate with the same calibre library via Calibre server, but this works perfect. The page is also fully accessible and everything works in browser. So the error is somewhere in config file.

Platforms:

SERVER: Synology (COPS)
READER: Marvin 3 (iOS app)

I'm especially highlighting this setting from the config file: $config['cops_full_url'] = 'http://SERVER.synology.me/cops/';

Full config file: config_default.txt

Did you follow this howto"?

Sure. But there is no solution to this problem, it is not Synology specific problem. I'm running COPS with no problem, only when connecting via Marvin App I cannot access the files.

I did some testing on ym own setup(s) with Marvin3 and I think it's not a cops or synology problem, but a Marvin3 problem (just like with the kobo browser).

To make it all work we need to change this line in cops: /*

• use URL rewriting for downloading of ebook in HTML catalog
• See Github wiki for more information
• 1 : enable
• 0 : disable */ $config['cops_use_url_rewriting'] = '1';

So change "0" to "1" and it should work. It did for me.

I have tried to set

$config['cops_use_url_rewriting'] = '1';

But I'm still getting same error. I can access the main categories but when i want to go deeper inside the category, the Marvin throw error.

Can you try with a bare minimum of altered settings in config_local.php? Maybe just:

• library
• rewrite
• timezone

Leave the rest default (and return the file config_default.php to it's original state).

It;s my suspicion that Marvin 3 does not cooperate well with custom columns, so just try without.

[seblucas]

Do you use password protection ?

[marioscube]

I do (as a setting in config_local.php).

But I suspect it’s a Marvin 3 problem, nothing to do with cops.

[dxcore35]

The password is removed. But still get:

I've contact Marvin developer and point him to this issue.

• Hopefully he will investigate to issue and reply here.

I tested on:

• Synology DS110j
• DSM 5.2-5967 Update 8
• COPS 1.1.2 (zip from github)
• Marvin 3 on iOS 12.0

Installed COPS in /volume1/web/cops Put the calibre libraries in /volume1/web/cops/Books (for testing purposes) Used this config_local.php (and changed nothing else):

<?php
/**

 *
 * @license    GPL 2 (http://www.gnu.org/licenses/gpl.html)
 * @author     Sébastien Lucas <sebastien@slucas.fr>
 */

    if (!isset($config)) {
        $config = array();
    }

    $config['calibre_directory'] = array ("Calibretest" => "./Books/calibretest/",
                                          "COPStest" => "./Books/COPStest/");

    $config['cops_full_url'] = 'http://192.168.1.XXX/cops/';

    $config['cops_recentbooks_limit'] = '1000';

    $config['cops_title_default'] = 'COPS 1.1.2 Synology';

    $config['default_timezone'] = 'Europe/Amsterdam';

    $config['cops_use_url_rewriting'] = '1';

    $config['cops_thumbnail_handling'] = '1';

Started Marvin3 on my iPad (iOS 12) used the webbrowser: http://192.168.1.XXX/cops/ And I could download my epubs to Marvin3.

To test if it works for you I suggest you try to do the same. You can add other options later.

@dxcore35 I have reproduced your error and it’s a COPS error!

Version 1.1.2 (zip file) seems to be ok, but later versions (git clone etc.) give errors.

EDIT Even version 1.1.2 has a lot of problems. Cops seems to be partly broken :(

I’m going back to an earlier version.

@dxcore35

On my config I traced the problem to a not working .htaccess.

On Synology .htaccess should be enabled, because to work Marvin 3 needs: $config['cops_use_url_rewriting'] = '1'; in config_local.php and all the rewrite rules in .htaccess.

There are still one or two smaller problems, but the developer of COPS is working on it.
