Patching ClearOS 7 to fix slow web interface

clearos7_fix.md

Since people that made ClearOS simply dropped the mic and left, existing instances suffer from very slow web interface with pages opening after a full minute or so, mostly because it tries to access the no longer existing marketplace on every page load. This is a great example of a severely bad architecture along with zero responsibility on the developer's side, but whatever.

Obviously, using severely outdated software is a bad practice and a huge security concern, but if you have no other options right now, this small guide will help you to make things work again.

In general, there are 3 things you need to do.

1. Disable all repos in /etc/yum/repos.d.

2. Find _display_page() function in /usr/clearos/framework/application/libraries/Page.php and comment the whole block starting with if (clearos_load_library('registration/Registration') && $this->framework->session->userdata('username')).

3. Find get_app_details() function in /usr/clearos/apps/marketplace/libraries/Marketplace.php and right after clearos_profile(__METHOD__, __LINE__); add the following:

   $minimal_response = json_encode(array(
     'code' => 0,
     'details' => (object)array(
       'pricing' => (object)array(),
       'eula' => '',
       'notes' => (object)array()
     )
   ));
   return $minimal_response;

After that the web interface should begin working normally.
