Bug with APCu : "ORM TreeListener does not support tree type:"

[jdeniau]

Hello,

First of all thanks for your great extensions.

I have a tree type entity configured with annotation in "nested" tree type.

I activated PHP5.5 APCu extension, and after some time, a weird exceptions is throwned:

ORM TreeListener does not support tree type:

(with nothing after the "type:")

The website works fine some hours and does this after.

If I clear the APCu cache, all works fine for several hours.

Here is the stacktrace :

Do you have some hint that could help me resolve this bug ?

hi, it looks like extension metadata cache was emptied for unknown reasons. I tested it before with apc and php 5.3 and it worked perfectly well. Cases are:

• if doctrine metadata cache gets cleaned or it is regenerated - extension metadata gets regenerated at the same time
• if extension metadata gets cleaned or invalidated - it also gets regenerated on the first request for metadata.

I cannot know what can cause it. What mapping driver is used for your tree metadata? Annotation, yaml or xml?

[jdeniau]

I use the annotation drive.

Here is my entity class :

use Doctrine\ORM\Mapping as ORM;
use Gedmo\Mapping\Annotation as Gedmo;

/**
 * Rubric
 *
 * @ORM\Table("rubric")
 * @Gedmo\Tree(type="nested")
 * @ORM\Entity
 */
class Rubric
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @Gedmo\TreeLeft
     * @ORM\Column(type="integer")
     */
    private $treeLeft;

    // treeRight, etc.
}

How extension listeners are initialized? You use symfony2 or stof bundle or something else? Does it share annotation reader with listeners, like in example or like in symfony2 configuration ?

Try changing it, if it is shared - do not, if it is not - do.

[jdeniau]

Yes I use symfony2 + stof extension bundle.

Apparently, the annotation reader is shared according to this file.

I will try to remove the method call and see if anything changes tomorrow.

I have same issue with PHP5.5 APCu on Ubuntu
This issue is present only with APCu i think
Restarting webserver helps for some time
I was doing some research and problem was with corrupted metadata in apc - instead of ascii chars I noticed some broken chars - maybe its segmentation fault of some kind
Here is my previous issue which is prolly related with this error: https://github.com/l3pp4rd/DoctrineExtensions/issues/796#issuecomment-21926602
