그래서 이미지 가져 오기 프로세스에서 메모리 사용 문제를 처리해야하는 “솔루션”을 포함하여 Magento에 버그를 제기했습니다.

해결책은 github의 https://github.com/sitewards/import_image_memory_leak_fix 에서 찾을 수 있지만 기본 아이디어는 다음과 같습니다.

이미지 프로세서에서 Mage_Catalog_Helper_Image::validateUploadFile실제로 destruct메소드를 호출하도록 수정했습니다 . 슬프게도 기본값 Varien_Image이 처리되지 않는 것처럼 보이므로 destruct자체 클래스를 추가해야했습니다.

<?php
/**
 * @category    Sitewards
 * @package     Sitewards_ImportImageMemoryLeakFix
 * @copyright   Copyright (c) Sitewards GmbH (http://www.sitewards.com/)
 */
class Sitewards_ImportImageMemoryLeakFix_Model_Destructable_Image extends Varien_Image
{
    /**
     * Constructor,
     * difference from original constructor - we register a destructor here.
     *
     * @param string $sFileName
     * @param Varien_Image_Adapter $oAdapter Default value is GD2
     */
    public function __construct($sFileName = null, $oAdapter = Varien_Image_Adapter::ADAPTER_GD2)
    {
        parent::__construct($sFileName, $oAdapter);

        // Initialize shutdown function
        register_shutdown_function(array($this, 'destruct'));
    }

    /**
     * Destroy object image on shutdown
     */
    public function destruct()
    {
        $oAdapter = $this->_getAdapter();
        if (method_exists($oAdapter, 'destruct')) {
            $oAdapter->destruct();
        } else {
            Mage::log('Image can not be destructed properly, adapter doesn\'t support the method.');
        }
    }
}

그런 다음 도우미를 다시 작성하십시오.

<?xml version="1.0"?>
<config>
    <modules>
        <Sitewards_ImportImageMemoryLeakFix>
            <version>0.1.0</version>
        </Sitewards_ImportImageMemoryLeakFix>
    </modules>
    <global>
        <models>
            <sitewards_importimagememoryleakfix>
                <class>Sitewards_ImportImageMemoryLeakFix_Model</class>
            </sitewards_importimagememoryleakfix>
        </models>
        <helpers>
            <catalog>
                <rewrite>
                    <image>Sitewards_ImportImageMemoryLeakFix_Helper_Catalog_Helper_Image</image>
                </rewrite>
            </catalog>
        </helpers>
    </global>
</config>

그리고 새로운 함수는 새로운 파괴 가능한 이미지 클래스를 호출합니다.

<?php
/**
 * @category    Sitewards
 * @package     Sitewards_ImportImageMemoryLeakFix
 * @copyright   Copyright (c) Sitewards GmbH (http://www.sitewards.com/)
 */
class Sitewards_ImportImageMemoryLeakFix_Helper_Catalog_Helper_Image extends Mage_Catalog_Helper_Image
{
    /**
     * Check - is this file an image
     *
     * Difference from original method - we destroy the image object here,
     * i.e. we are not wasting memory, without that fix product import with images
     * easily goes over 4Gb on memory with just couple hundreds of products.
     *
     * @param string $sFilePath
     *
     * @return bool
     * @throws Mage_Core_Exception
     */
    public function validateUploadFile($sFilePath) {
        if (!getimagesize($sFilePath)) {
            Mage::throwException($this->__('Disallowed file type.'));
        }

        /** @var Sitewards_ImportImageMemoryLeakFix_Model_Destructable_Image $oImageProcessor */
        $oImageProcessor = Mage::getModel('sitewards_importimagememoryleakfix/destructable_image', $sFilePath);
        $sMimeType       = $oImageProcessor->getMimeType();
        $oImageProcessor->destruct();

        return $sMimeType !== null;
    }
}
