Redeclare drupal_path_initialize with Redis module installed

Hmm, idk. From the errors you posted, this looks to be an issue with Redis and nothing to do with CBP at all since it does not redefine any functions. If Redi's is redefining core functions, then the issue should be reported there instead. Not sure why its trying to redefine core functions though since thats generally bad practice in php unless it's within a class and extending a method. Let me know what you find. Adding an if clause to check for a function's existence and running an include is nothing big but redefining of functions is a little different. However, I dont use include. I make sure to use require_once() so that the file is only included once no matter what. If everything is coded properly, there should be no need for the if clause check on the function existence to begin with. The fact that somehting isnt coded properly though is what is causing the problem and thus causing redefinition where there shouldnt be any at all.

Ok well there is no reason not to have an if clause there, it wont hurt anything. I can add it in, but there is a possibility that it still wouldnt work for others depending upon the load order of the php files. Example, if redis is included/require_once'd AFTER cbp, then all bets are off :/ Not sure what scenario that would happen in but it could be a possibility. Hopefully it uses require_once and not include() ;) I cant remember the last time I actually used the include() method.

See if this fixes the issue or not, if so, I'll add this in now. The "path_inc" variable was not available on my default D7 so it isnt going to exist for most people. The elseif should cover those of us who do not run Redis.

$inc_path_var = variable_get('path_inc');
   if (!empty($inc_path_var) && !function_exists('current_path')) { require_once($inc_path_var); }
