Project: 
Introduced in branch: 
8.x
Introduced in version: 
Description: 

The function system_get_module_info() and the class that is used by it (ModuleInfo extends CacheArray) has been removed from Core.

It was introduced as a performant way to get a certain information from all module .info files, like the name and only existed in 8.x as it has not yet been backported.

There is no need anymore for this, as a lot of information has been removed from .info files so the problematic memory overhead no longer exists.

Before

$names = system_get_module_info('name');

After

$modules = system_get_info('module');
$names = array();
foreach ($modules as $name => $module) {
  $names[$name] = $module['name'];
}
