[DC-770] Result Cache

Doctrine result cache isn't working properly.

Here a simple example, when I'm calling query->execute (); parentProgram is related to a video.
Into the Doctrine_Query_Abstract.php file

line 1014 : I have just add some code to output data.
[code]
if ($cached === false)

{ // cache miss $stmt = $this->_execute($params); $this->_hydrator->setQueryComponents($this->_queryComponents); $result = $this->_hydrator->hydrateResultSet($stmt, $this->_tableAliasMap); $oVideo = $result[0]; echo "not cached "; var_dump (count ($oVideo->parentProgram->getReferences ())); $cached = $this->getCachedForm($result); $cacheDriver->save($hash, $cached, $this->getResultCacheLifeSpan()); }

else

{ $result = $this->_constructQueryFromCache($cached); $oVideo = $result[0]; echo "cached "; var_dump (count ($oVideo->parentProgram->getReferences ())); exit (0); }

[/code]

The output of a query execution (the first with an empty APC cache) with "useResultCache" is :

not cached int(1)
cached int(0)

The problem is coming from the serialize php function that can't serialize protected properties..
getReferences is a getter to a protected property.. So data result can't work properly.

A solution could be use __sleep function, and a public property that contain all important protected data.
