True drush cc all

If one were to dig into drush's codebase, they'd find out that drush cache-clear all (or drush cc all) is not equivalent to clearing all the caches that you can see if you just type drush cache-clear (as I would personally expect).

For example, this is what you get on a Drupal site that has Token, Views and Varnish modules installed.

$ drush cache-clear

Enter a number to choose which cache to clear.
 [0]   :  Cancel         
 [1]   :  all            
 [2]   :  drush          
 [3]   :  theme-registry 
 [4]   :  menu           
 [5]   :  css-js         
 [6]   :  block          
 [7]   :  module-list    
 [8]   :  theme-list     
 [9]   :  registry       
 [10]  :  token          
 [11]  :  varnish        
 [12]  :  views

But if one were to run drush cache-clear all this will not clear token, varnish, views or even block. This is because drush cc all does only two things: it clears internal drush caches and it invokes drupal_flush_all_caches(). This is a core Drupal API that is not aware of the various implemenations of hook_drush_cache_clear().

What we provide here is a re-implemention of all so that it truly clears all the caches.

Installation

Place ccall.drush.inc in one of the locations where drush will look for it. Currently, the official documentation says these locations are:

• The "/path/to/drush/commands" folder.
• Folders listed in the 'include' option (see drush topic docs-configuration).
• The system-wide drush commands folder, e.g. /usr/share/drush/commands
• The .drush folder in the user's HOME folder.
• /drush and /sites/all/drush in the current Drupal installation
• All enabled modules in the current Drupal installation
• Folders and files containing other versions of drush in their names will be skipped (e.g. devel.drush4.inc or drush4/devel.drush.inc). Names containing the current version of drush (e.g. devel.drush5.inc) will be loaded.
