Access to Memory (AtoM)

Hi Radda, can you take a look at this?

It looks like an APC/APCu cache problem. And it's probably happening the same with other settings. The settings cache is not being cleared after changes and it's showing the following notice:

Jul 04 11:33:11 symfony [notice] {sfWebDebugLogger}  Notice at /home/radda/www/atom-2/vendor/symfony/lib/cache/sfAPCCache.class.php on line 150 (Undefined index: key)

https://github.com/artefactual/atom/commit/0f69c8a844a5a47db86fc85a2fd75b0246d95f27

After that commit we check if the 'apcu' extension is enabled in ...

https://github.com/artefactual/atom/blob/qa/2.3.x/vendor/symfony/lib/cache/sfAPCCache.class.php#L42

Changing the 'cache_list' key after when the settings are removed from the cache ...

https://github.com/artefactual/atom/blob/qa/2.3.x/vendor/symfony/lib/cache/sfAPCCache.class.php#L138

In my case I have the 'apcu' extension loaded but the info key is still being 'info'.

I'm using Apache2, PHP 5.5.9 and I have both modules (apc and apcu) installed

So it looks like an issue between both extensions. If php 5.5 or higher is being used it should use the APCu and OPCache extensions and not APC. I've tried to uninstall php-apc but the issue keeps happening.

Sevein, as you know a lot more about this, could you take a quick look? Please, let me know if you need more info about my configuration. Thanks!

What's the output of `phpversion('apc')` for you?
I see "4.0.2", I'm using trusty (Vagrant box) - this is still using "key" instead of "info". I'm aware that APCu fixed that problem and started using "info" but Ubuntu 14.04 never brought that from upstream. I'm assuming that the situation is the same in Ubuntu 12.04 but I'll double check.

Radda, what do you think of this? https://github.com/artefactual/atom/pull/402 - can you test it?

Awesome Sevein, I'm using Ubuntu 14.04 and phpversion('apc') is '4.0.7'. The fix worked for me, and I've merged it in 5829948

Thanks!
