Hello,
I made an increment for file engine system.
My problem was that in APC cache, the cache is not shared between CLI
and the web app... then I did that with fileEngine using flock... it's
not workink on windows.
<?php
/**
* FileEngine with inc/dec
*
* @author Sandreu
*
* @property SplFileObject $_File
*/
App::import('Cache/Engine', 'FileEngine');
class FileIncEngine extends FileEngine {
public function increment($key, $offset = 1) {
if ($this->settings['isWindows']) throw new
CacheException(__d('cake_dev', 'Files cannot be atomically decremented
on windows.'));
if (!$this->_init || $this->_setKey($key) === false) {
if (!$this->write($key, $offset, $this-
>settings['duration'])) return false;
return $offset;
}
$lock = $this->settings['lock'];
$this->settings['lock'] = false;
$this->_File->flock(LOCK_EX);
$val = $this->read($key);
if (!is_integer($val)) {
$this->_File->flock(LOCK_UN);
return false;
} else {
$val += $offset;
}
$this->_File->rewind();
if (!$this->write($key, $val, $this->settings['duration']))
{echo 'error'; return false; }
$this->_File->flock(LOCK_UN);
$this->settings['lock'] = $lock;
return $val;
}
public function decrement($key, $offset = 1) {
return $this->increment($key, 0-$offset);
}
}
?>
