CCache/CMemCache issues


It seems trying to cache an empty array will cause unserialize failed when retrieving.

memcached-tool dump showed results:


trying Yii::app()->cache-get($key)

Yii unserialize() expects parameter 1 to be string, array given

See CCache.php Line 84, I modified





    $data = $value;






Or add

                if($value === false || ( is_array($value) && empty($value) ) )


on line 144 to avoid set an empty array value.

I don’t know if it is the right way, just works.

Another question, I write a class named CacheManager, just a proxy call for Yii::app()->cache, like this

public function set($key, $value)


    Yii::app()->cache->set($key, $value);


But I can find unserialized data in cache by this function call, calling Yii::app()->cache->set directly always store serialized data in cache, I don’t understand why, I had to add checks above to CCache.

any suggestions will be appreciated.

each realization of CCache in getValue() function can’t return array (if you didn’t set it without using of CCache)
