DunglasApiParser: Maximum function nesting level of '10000' reached, aborting

[Drachenkaetzchen]

Hi,

I use NelmoApiDocBundle with DunglasAPI. In one model, I have a self-referencing relation:

/**
 * @ORM\Entity(repositoryClass="Gedmo\Tree\Entity\Repository\NestedTreeRepository")
 * @Gedmo\Tree(type="nested")
 * @ORM\Table(indexes={@ORM\Index(columns={"lft"}),@ORM\Index(columns={"rgt"})})
 * The entity for our footprint categories
 * @TargetService(uri="/api/footprint_categories")
 */
class FootprintCategory extends AbstractCategory
{
    /**
     * @Gedmo\TreeParent
     * @ORM\ManyToOne(targetEntity="FootprintCategory", inversedBy="children")
     * @ORM\JoinColumn(name="parent_id", referencedColumnName="id", onDelete="CASCADE")
     * @Groups({"default"})
     */
    protected $parent;

    /**
     * @ORM\OneToMany(targetEntity="FootprintCategory", mappedBy="parent")
     * @ORM\OrderBy({"lft" = "ASC"})
     * @Groups({"default"})
     */
    protected $children;

This causes NelmioApiDocBundle to hit the recursion limit. Some of the backtrace lines:

[willdurand]

poke @dunglas

[dunglas]

@FELICITUS is this bug stil accurate?

[Drachenkaetzchen]

I need to re-test, is the NelmioApiDocBundle working again with latest master?

[willdurand]

@FELICITUS well, deprecated notices put aside, yes.

[dunglas]

Not with dev-master of ApiBundle. Only 1.0 will be supported until the release of 2.0.

[willdurand]

ah right!

[amerryma]

Were you able to resolve this without updating the api-bundle to 2.0?

[Drachenkaetzchen]

I just tested it with the PR of api-platform/core#225, but this issue still persists.

[teohhanhui]

Isn't this an issue with breaking circular reference? You can avoid the problem by not having circular references in your serialization (by properly using serialization groups for normalization/denormalization)...

[marek-l]

Any news with this issue?

[marcin-piela]

https://github.com/nelmio/NelmioApiDocBundle/blob/master/Parser/DunglasApiParser.php#L184

I think in DunglasApiParser.php we need to add statement:

if ($class != $resource->getEntityClass()) {
    $data['children'] = $this->parseClass($resource, $class, $io);
} else {
    $data['children'] = [];
}

[nicolasricci]

thanks @marcin-piela for the snippet
+1 to fix this issue.

[teohhanhui]

@dunglas This is not really fixed yet.

A proper cycle detection/breaking mechanism needs to be implemented for handling e.g. the case of:

(AggregateOffer)-[:offers]->(Offer)-[:addOn]->(Offer)

[teohhanhui]

Refer to #121 which uses a visited stack.
