Hello everyone !
I tried to patch the ysfDimensionsPlugin for use with sfSqliteCache,
as neither APC nor eAccelerator are available on my shared host.
At first I thought it was just a matter of applying this patch (http://
trac.symfony-project.org/ticket/6267) and serializing/unserialising
cache data. But it turned out that I also had to change the cache
directory when the dimension change, which gives me one db file in
each dimension directory...
So I was wondering how to avoid duplicate db files ?
And also if it is possible to avoid serializing cache data ?
Thanks for your wise advices !
Here are my changes:
in ysfConfigDimension.php:
public function setCache(sfCache $cache){
$this->cache = $cache;
}
in ysfProjectConfiguration.php:
/**
* Sets the project dimension.
*
* @param array The configuration dimension as an array
*/
public function setDimension($dimension)
{
if ($dimension === null || $dimension === false)
{
$this->dimension = null;
// if dimension changes, change cache dir
$this->setCacheDir($this->getRootDir().'/cache');
}
else
{
try
{
if(!$this->hasDimension())
{
$this->dimension = new ysfConfigDimension(
$this->getEventDispatcher(),
(!isset($this->debug) || (isset($this->debug) && $this-
>debug === true))
? new sfNoCache()
// Patch to allow other cache handler
: $this->getDimensionCacheHandler()
);
}
// set dimension
$this->dimension->set($dimension);
sfConfig::set('sf_dimension', $this->dimension->getName());
// if dimension changes, change cache dir
$cache_dir = $this->getRootDir().'/cache/'.$this->dimension-
>getName();
$this->setCacheDir($cache_dir);
// Reconfigure SQLite cache
$this->dimension->setCache(
new sfSQLiteCache(
array(
'database' => sfConfig::get('sf_cache_dir').'/
cache.sqlite',
'automatic_cleaning_factor' => 0,
'lifetime' => 86400
)
)
);
}
catch (sfException $e)
{
if(method_exists($e, 'asResponse'))
{
// handle exception early on and exit if something bad happens
$e->asResponse()->send(); exit;
}
else
{
echo $e->getMessage(); exit;
}
}
}
}
