This is a proof of a concept - implementation of Varien_Object from Magento 1 done on C as a PHP extension. The reason behind this work is to investigate possible performance gain/loss by manually converting a core Magento class to a pre-compiled extension.
The implementation is very close to original Varien_Object. There are minor differences, made for optimization purpose. However, they won't show up, if the class won't be used in some extremely stupid funny way.
Supported Magento versions:
- Magento CE 1.6.0.0 and higher
- Magento EE 1.11.0.0 and higher
Tested PHP versions:
- 5.3.14
- 5.6.5
Tested platforms:
- Windows 7 64-bit
- Debian 7.8
Used compilation tool:
- VC 2008 Express
- GCC 4.7.2
Results of the performance comparison are in docs/PERFORMANCE.md
See BUILD.md Already compiled php extension for Windows / PHP 5.3.14 is here: php_mage.dll
There are unit tests for the whole implementation in /tests directory. They are written in PHP, using PHPUnit. Running is pretty straightforward:
cd tests/unit
phpunit
The framework supports running unit tests against either php_mage or native Varien_Object. See phpunit.xml.dist for the option, how to configure that.
See performance tests README.md.
Having the built extension, just put it into php.ini as any other extension.
extension=php_mage.dll
The extension will add Varien_Object class to the list of internal PHP classes. Magento won't need to autoload this class, so that it won't load the original Varien_Object that is coming with the system.
You can completely delete the /lib/Varien/Object.php file from Magento in order to ensure, that it runs using php_mage extension only.
