我们已经建立了一个在线程之间共享的原则缓存,扩展了一个线程安全堆栈。
警告部分代码是为了演示目的而被简化的。
class work extends \Collectable{
protected $parameters;
public static $doctrine_mongodb;
public function __construct($parameters){
$this->parameters = $parameters;
}
public function run()
{
try{
$loader = require __DIR__.'/../../../../../../vendor/autoload.php';
static::$container = unserialize($this->worker->container);
static::$doctrine_mongodb = static::$container->get('doctrine_mongodb');
...
DO WORK
$dm = static::$doctrine_mongodb->getManager();
$repo = $dm->getRepository('Bundle:Document');
$ris = $this->worker->doctrinecache->FindOneBy($repo, array('key' => $val));
...
}catch(\Exception $e){}
}
}
注意:在工作类中,我们有工作代码的并行执行,在那里我们可以安全地使用学说公共缓存。
共享实体管理器不一样,因为文档是分离的,但用于阅读目的是好的。如果有人需要管理实体,可以使用合并原则的方法。
class SWorker extends \Worker{
public $env;
public $debug;
public $mongodb_cache_engine;
public function __construct( $env, $debug, $doctrinecache, $workParams){
$this->workParams = $work;
$this->env = $env;
$this->debug = $debug;
$this->doctrinecache = $doctrinecache ;
}
public function start($options = null){
return parent::start(PTHREADS_INHERIT_NONE);
}
public function run(){
require_once __DIR__.'/../../../../../../app/bootstrap.php.cache';
require_once __DIR__.'/../../../../../../app/AppKernel.php';
$kernel = new \AppKernel($this->env, $this->debug);
$kernel->loadClassCache();
$kernel->boot();
$this->container = serialize($kernel->getContainer());
}
}
在 Sworker 类中,我们为线程准备 symfony 环境。为此,请转至 svenpelster https://github.com/krakjoe/pthreads/issues/369。
class doctrinecache extends \Stackable{
public function __call($MethodName, $arguments){
$repository = array_shift($arguments);
$documentName = $repository->getDocumentName();
$hash = $this->generateHash($MethodName, $documentName, $arguments);
return $this->cacheIO($hash, $repository, $MethodName, $arguments);
}
public function cacheIO($hash, $repository, $MethodName, $arguments){
$result = isset($this["{$hash}"])? $this["{$hash}"] : NULL;
if(!$result){
$result = call_user_func_array(array($repository, $MethodName), $arguments);
$this["{$hash}"] = $result;
}
return $result;
}
}
最后
$doctrineCache = $this->kernel->get('doctrineCacheService');
$pool = new \Pool($workerNumber, SWorker::class, [$this->kernel->getEnvironment(), $this->kernel->isDebug(), $doctrineCache ,$workParams]);
while(current($works ))
{
$pool->submit(current($works ));
next($works);
}
$pool->shutdown();
while(current($works ))
{
$arrayResults[] = current($works )->getResults();
next($works);
}
