local.xml在多个Magento文件中被硬编码.

local.xml is hardcoded in multiple Magento files.

因此，如果要为此实现自己的文件名选择，则必须分别覆盖几个核心类/方法/函数.

So if you want to implement your own file name selection for this, you'd have to override several core classes/methods/functions respectively.

对local.xml *的扫描显示-除其他外-您必须修改/app/Mage.php.那是因为您不能覆盖Mage(这是一个final类).

A scan for local.xml* shows that - amongst other things - you'd have to modify /app/Mage.php. That's because you cannot override Mage (it's a final class).

请注意，可以修改/app/Mage.php，但是每次升级到下一个Magento版本都会覆盖您的更改.

Be aware that modifying /app/Mage.php is possible, but every upgrade to the next Magento version will overwrite your changes.

如果可以忍受，您还必须至少覆盖

If you can live with that, you'd additionally have to override at least

Mage_Core_Model_Config
Mage_Core_Model_Layout_Update

也许还有

Mage_Install_Model_Installer_Config
Mage_Adminhtml_Block_Notification_Security (1.5.1)

根据您的需求.

设置文件名选择方法，例如在一个助手中:

Setup your file name selection method, e.g. in a helper:

class Mynamespace_Mymodule_Helper_Data extends Mage_Core_Helper_Data
{
    public function getLocalXMLFileName()
    {
        return getenv('MY_XML') . 'xml';
    }    
}

在您覆盖的核心类中，只需调用您的辅助方法，例如改变

In your overridden core classes just call your helper method, e.g. change

$updateFiles[] = 'local.xml';

到

$updateFiles[] = Mage::helper('mymodule')->getLocalXMLFileName();
