Doctrine_Cache_Apc not works in symfony task - caching

Question

in my doctrine table i got this
public function countHitsFor($object_id) {
return $this->createQuery('s')
->select('COUNT(*) as count')
->where('s.target_id = ?', $object_id);
->useResultCache(true, 3600, 'hits_for_'.$object_id)
->execute(array(), Doctrine_Core::HYDRATE_SINGLE_SCALAR);
}
so if i use this from action its works fine,
first request make sql query,
second load Hits from cache
and what i want is to warm up cache from symfony task
i start task and for each object i call StatTable::getInstance()->countHitsFor($object_id) to create cache data for query, but its not works
after task first request to action makes sql query
UPD
ProjectConfiguration
public function configureDoctrine(Doctrine_Manager $manager)
{
$manager->setAttribute(Doctrine_Core::ATTR_RESULT_CACHE, new Doctrine_Cache_Apc());
}
task
<?php
class warm_up_stat_cacheTask extends sfProgressTask
{
protected function configure()
{
$this->addOptions(array(
new sfCommandOption('application', null, sfCommandOption::PARAMETER_REQUIRED, 'The application name', 'frontend'),
new sfCommandOption('env', null, sfCommandOption::PARAMETER_REQUIRED, 'The environment', 'prod'),
new sfCommandOption('connection', null, sfCommandOption::PARAMETER_REQUIRED, 'The connection name', 'doctrine'),
// add your own options here
));
$this->namespace = 'my_tasks';
$this->name = 'warm_up_stat_cache';
$this->briefDescription = '';
$this->detailedDescription = '';
}
protected function execute($arguments = array(), $options = array())
{
// initialize the database connection
$databaseManager = new sfDatabaseManager($this->configuration);
$connection = $databaseManager->getDatabase($options['connection'])->getConnection();
$contextInstance = sfContext::createInstance($this->configuration);
$Objects = ObjectTable::getInstance()->findAll();
foreach ($Objects as $obj) {
StatTable::getInstance()->countHitsFor($obj->id);
}
$obj->free();
}
}
comand
php symfony my_tasks:warm_up_stat_cache
UPD2
as i understand the problem is in APC
public function countHitsFor($object_id) {
$ckey = 'hits_for_'.$object_id;
if (!apc_exists($ckey))
apc_store($ckey,$this->createQuery('s')
->select('COUNT(*) as count')
->where('s.target_id = ?', $object_id);
->useResultCache(true, 3600, 'hits_for_'.$object_id)
->execute(array(), Doctrine_Core::HYDRATE_SINGLE_SCALAR));
return (int) apc_fetch($ckey);
}
this not works too, may be APC makes prefixes for keys for different environments?

Answer 1

The problem is in Apc, its use separate memory spaces for Apache (mod_php) and for Cli.
I made simple key-value storage on MyISAM table.
Thanks.
