Magento-HHVM.md

Running Magento Enterprise Edition with Facebook HipHop HHVM

Prerequisites

Hardware

MacBook Air (MBA) Mid 2012

Virtualbox (VB): Ubuntu 12.04.2 LTS (GNU/Linux 3.2.0-23-generic x86_64) via vagrant.

Software

MBA with Apache 2 with mod_php Version 5.3.19 with MySQL 5.5 (MAMP)

VB with fresh pulled HHVM sources with MySQL 5.5

Magento

I ran here a big customized Magento EE 1.12 store from a big Swiss scout store. A lot of custom price rules for many different groups and some fancy discount types.

URL schema is different from the official demo store: www.customer.ch/[de|fr]/index.php to map automatically different languages.

Magento Cache activated. MySQL database slightly optimized via mysqltuner.pl

• 5000 SKUs
• 237 categories
• 48.000 url rewrites
• 4 store views
• FPC disabled

Magento EE sources has been imported into the VM. Not via shared folders or NFS. There were previously some weird long request times with HHVM when using shared folders.

Compile and Download HipHop

You can use the install script install-hhvm.sh for compiling and installing hiphop https://github.com/jakoch/php-hhvm.

But change the hiphop source in function get_hiphop_source() to the special Magento hiphop https://github.com/danslo/hiphop-php source.

Optionally: You can remove all the last lines after ## Success in the script install-hhvm.sh.

Official FB "How to" compile: https://github.com/facebook/hiphop-php/wiki

Prebuild packages will not work with Magento.

HHVM config.hdf

Options for the config.hdf file: https://github.com/facebook/hiphop-php/blob/master/hphp/doc/options.compiled

Please see the to this gist attached file hhvm.hdf.

Buggy is the PHP_SELF and SCRIPT_NAME which will not be properly set therefore hardcoded. Also the rewrite rules can be more optimized.

Magento Errors

I'm not quite sure if that is still a problem with SimpleXML or with buggy Magento code.

Fixes:

• File site/app/code/core/Mage/Core/Block/Template/Facade.php every: $key = (string)$key;

Unfixable:

• There are also some errors in the site/app/code/core/Mage/Eav/Model/Entity/Collection/Abstract.php on line 441 but that results from strange code in phtml files ... 8-)

Not every category will work but 98% of them.

Search

Not possible due to HHVM shows this error:

Notice: Undefined index: 0 in /var/www/customer-dev/site/app/code/core/Mage/Catalog/Model/Layer/Filter/Price/Algorithm.php on line 368

There is something weird in our code base, not in HHVM.

Performance Test

Multiple shift-reloads in the FF 23 browser in two tabs. Times are approximate.

Request Type	HHVM	MAMP	MAMP-APC [1]
CMS Page	450ms	2.5s	820ms
Category View [2]	980ms	4.6s	3.5s
Product View [3]	500ms-1s	4.7s	3.1s

Onepage SaveBilling	236ms	2.3s
Onepage SaveShipping	251ms	2.4s
Onepage SavePayment	486ms	3.28s
Onepage success	562ms	3.25s

1. MAMP-APC runs with PHP 5.4.16
2. containing 8 products
3. configurable product with two options and one customer rating
4. POST to cart with redirect to product view and listing cart content
5. First call of the basket page
6. Reloads
7. Initial load of the page checkout/onepage after that normal checkout process

ab -n 20 -c 5

In both tests: PHP 5.4.16

Conclusion

Missing is a test where we rely on Redis, Percona, php-fpm + nginx.

Also missing test: The HHVM should be put behind a nginx server and even here the cache should connect to Redis.

Facebook is working hard on HHVM. A lot of commits take place every day!

Big kudos to https://twitter.com/daniel_sloof for fixing HHVM errors related to Magento!

That would be one future for PHP.
