Solve the following python programming problem given the following code:
def _cachedfunc(cache, makekey, lock) : 
    def decorator(func) : 
        stats = [0, 0] 
        def wrapper(* args, **kwargs) : 
            key = makekey (args, kwargs) 
            with lock : 
                try : 
                    result = cache [key] 
                    stats [0] += 1 
                    return result 
except KeyError : 
                    stats [1] += 1 
result = func (* args, ** kwargs) 
            with lock : 
                cache [key] = result 
return result 
def cache_info() : 
            with lock : 
                (hits, misses) = stats 
                maxsize = cache.maxsize 
                currsize = cache.currsize 
return CacheInfo (hits, misses, maxsize, currsize) 
def cache_clear() : 
            with lock : 
                cache.clear () 
wrapper.cache_info = cache_info 
        wrapper.cache_clear = cache_clear 
        return functools.update_wrapper (wrapper, func) 
return cache
