Transformer mappings circular dependencies

[IlCallo]

Now that it's possible to put mappings on $relations, I tried to add them everywhere.
Then I got stuck into a cicular dependency of those mappings and a segmentation fault happened.

If I remember correctly, Fractal prevents circular dependencies cutting them down after X iterations, but with the new layer of mapping used to eager load relations I guess this behaviour wasn't taken into account.

Oh, this makes sense. We’re traversing the transformers recursively, and if two transformers reference each other I suppose it ends up with an endless loop. Can’t believe I didn’t think about this.

I’ll think some how we best can solve this, but it definitely needs fixing ASAP, as this sounds like a very normal use case

This is now fixed with v3.0.2
