@fenollp I updated the PR description and its contents :) This should solve circular references resolution for good. Let me know if you have any questions or concerns |

Hi & thanks for taking the time to look into this!
Mostly LGTM, just: I see you're not using the visitref utils you're introducing in these two places and it feels like this was fogotten?
func (loader *Loader) resolveLinkRef(doc *T, component *LinkRef, documentPath *url.URL) (err error)func (loader *Loader) resolvePathItemRef(doc *T, pathItem *PathItem, documentPath *url.URL) (err error)
Could you comment on or fix that please?

Thanks for a quick review! I indeed missed a couple of functions. It's ready for re-review |

This PR adds a test scenario that leads to failure of resolving recursive references.
After troubleshooting for a while, I realized that current reference tracking algorithm in not perfect and will always have some edge cases, so I decided to try fixing that for good.
During reference resolution, we keep track of all previous references, and if we find out that the reference is already being resolved, we register a backtracking callback that will assign a pointer to the resolved schema once it's done.
This guarantees that schema will always be resolved regardless of the depth.
