PIM doesn't like APC and PHP 5.5 :-) about pim-community-dev HOT 2 CLOSED

Hi Sylvain,

Thanks for the feedback. But as stated in the documentation, we use APC for user cache, not for opcode cache (the part that is not compatible with PHP 5.5).

So you should be able to use APCu as a drop-in replacement. Some of our devs are working on PHP 5.5 with APC user cache without any problem (Ubuntu 13.10), and withtout even notice that something changed as Ubuntu automatically replace php-apc package by php-apcu package for PHP 5.5.

Can you test with APCu and give us some more information about your environment, so I can update the documentation on the pre-requisites ?

And by the way, what are the problem you have with APC and PHP 5.4 ? It works pretty well, and we have several installation in production with it without any problem.

Thanks !

Hello Benoit,

Regarding using PHP 5.4 and APC, I had several issues with Magento on Ubuntu 12.04 in december for a live server, it was problems with include and require functions, Zend library files were not found because I use capistrano to deploy my code and it uses symlinks in several places, the source came from that I think. I read somewhere at this time similar issues and incompatibilities with PHP 5.4 and APC, for this reason I kept that in mind. There is now a patch for Magento and PHP 5.4, I didn't had the opportunity to test it but I don't think that it resolves those symlink issues. Maybe PHP 5.4 and APCu it's better.

Now I am trying on dev environment PHP 5.5 because there is an integrated OpCode cache and should replace APC. After those several years of Magento experience, for me performance is one of my priority. As I expect to get a demo environment on a live server with Magento, Akeneo and OroCRM. I take the opportunity to make that work with PHP 5.5 and see if it makes sense and can go further with that.

I did a vagrant box and a puppet provision which will be similar to my live server:

• Ubuntu 12.04 LTS
• Apache 2.4.7 (I had to adapt all .htaccess, deny from all is not supported anymore)
• PHP 5.5.9
• MySQL 5.5.35

Thanks about APCu, I forgot this new module for PHP. I added it and now it works well.
