 Posted: Thu Feb 06, 2014 10:50 am Post subject: Need help for gzip cache file handler |
 |
|
Hello everyone,
I recently posted a Smarty 3 Cache plugin enabling Cache handling in a database through PDO support and optionnal Gzip compression :
http://www.smarty.net/forums/viewtopic.php?t=24716
It works well on my dev server, but for several reasons, I still can't test it on a production environment, and since my production db is heavily loaded, the probability to crash it isn't insignificant.
So, I went out with the idea to use File cache handling, but with Gzip support. My website running millions of Urls (I have way too much, we're working on it), my file cache size was Gigabytes huge, so I first gzdeflate() what I assigned to Smarty, so as to reduce the cache size.
The problem is, this way, Smarty creates a .php cache file, mixing PHP code and gzip-encoded data in the same file. As it is not an issue in most cases, sometimes the gzinflate() works badly, and the rendering is crashed.
As a consequence, I decided to write another cache plugin, that would extends the File Cache Handler, but which would write a smarty .php cache file fully gzipped (and I would no longer gzdeflate() what I assign to Smarty, since the whole file would be gzipped by Smarty).
Here's my code :
File Smarty.cacheresource.file.gzip.php :
| Code: |
class Smarty_CacheResource_File_Gzip extends Smarty_Internal_CacheResource_File {
/**
* Read the cached template and process its header
*
* @param Smarty_Internal_Template $_template template object
* @param Smarty_Template_Cached $cached cached object
* @return booelan true or false if the cached content does not exist
*/
public function process(Smarty_Internal_Template $_template, Smarty_Template_Cached $cached=null)
{
$_smarty_tpl = $_template;
$content = gzinflate(file_get_contents($_template->cached->filepath));
return $content;
}
/**
* Write the rendered template output to cache
*
* @param Smarty_Internal_Template $_template template object
* @param string $content content to cache
* @return boolean success
*/
public function writeCachedContent(Smarty_Internal_Template $_template, $content)
{
return parent::writeCachedContent($_template, gzdeflate($content));
}
}
|
Usage :
| Code: |
$Smarty->SetCaching(Smarty::CACHING_LIFETIME_CURRENT);
$Smarty->SetCacheLifetime(3600);
$Smarty->SetCachingType('file_gzip');
$Smarty->Assign('MyCode', 'Sample text');
$Smarty->Display('string:{$MyCode}');
|
On the first Display() call (cache doesn't exist), Smarty correctly writes a gzip-encoded file into the cache folder.
However, on the next calls, Smarty displays the gzip content hieroglyphs, without decoding it.
Can you help me to figure this out ?
Thanks,
Ben |

As you don't include the PHP any longer. The content must be parsed by eval.
| Code: | public function process(Smarty_Internal_Template $_template, Smarty_Template_Cached $cached=null)
{
$_smarty_tpl = $_template;
$content = gzinflate(file_get_contents($_template->cached->filepath));
if (isset($content))
eval("?>" . $content);
return true;
}
return false;
}

| It works on the production environment of a high traffic website for more than 3 weeks. Performances are great. |
