Fixes #658

Does this PR introduce a breaking change?

Yes
No

Additional context

We need to figure #608 out as soon as possible.
Basically, we need to make a call whether or not to return validation results that cannot be associated with any document, as we do now.
If we happen to do so, we'll keep reporting duplicate errors under certain circumstances.

marbemac

We should probably dig in re the question you pose in the original PR description soon.

+        while ($ref in refMap) {
+          $ref = refMap[$ref];
+        }


This is an odd looking piece of code, could you add a comment describing what this is for?

Or just in general maybe this entire hasRef logic tree (line 55-74) could be pulled out to its own function, with a comment describing what it does (or some descriptive tests)?

marbemac

From code perspective looks alright to me, but I didn't do any verification it fixes the original issue in a satisfactory way. @nulltoken if you have time, would be awesome if you could spin this PR branch up and do a quick verification that the changes here solve #658.

These might be a good fit for the JSON package (where we already have a bunch of pointer helpers etc)?

However, I'm on a bit on the fence regarding the reported errors....

From a "spec fixer" perspective, second [65:15] line reads a bit strange as this file doesn't contain any paths section.
This path only makes sense in the context of the first file. But there's no hint to the file that indirectly suffers from this issue.
If only the issue in URIError.yaml is fixed, my understanding is that Spectral will report the file as fine. Which is somehow wrong as it still references parts of a remote file containing issues.

Thoughts?

Yeaaah, I guess we'd need to provide a json path relevant to that file.

It the referenced remote file contains issues, that error will still be reported, but for the file containing errors (the referenced one)
Technically, URIError.yaml does not contain any errors, it's the remote reference that does.
I suppose we could add a hint that URIError.yaml references a XYZ file that contains ABC errors.

Note, this change was partially driven by Studio where we show errors relevant to the current files and ignore errors coming from $refs.

👍

I do agree.

I suppose we could add a hint that URIError.yaml references a XYZ file that contains ABC errors.

That would also awesome. If that hint would be tied to some new built-in rule and that the user could change the severity of that rule, that would be even awesome-er ;-)

cc @philsturgeon you may find the above convo quite interesting considering the Spectral VS Code plugin.

P0lip · 2019-12-06T19:18:20Z

Alright, so I'm working on the path issue.
Pushed a commit 88eecf6.
Still needs to cleanup this up a little bit as well as update a few tests

marbemac · 2019-12-09T04:40:03Z

Not sure what the two files in question look like, but assuming the following:

c:/_work/spectral/repro/URIError.yaml has a ref at paths./test.get.responses.400 that targets https://[REDACTED]]/static/schemas/common/v2/library.openapi.yaml#/responses/bad-request

I'd expect the resulting error report to look like:

https://[REDACTED]]/static/schemas/common/v2/library.openapi.yaml
 65:15  warning  schema-strings-maxLength  String typed properties MUST be further 
described using 'maxLength'. Error: components.schemas.Error.properties.error.maxLength is 
not truthy
 65:15  warning  schema-strings-maxLength  String typed properties MUST be further
described using 'maxLength'. Error: responses.bad-request.content.application/json
.schema.properties.error.maxLength is not truthy

Basically if we're reporting on another file, still reporting on inner paths relative to that file - in the example above it's the #/responses/bad-request root pointer that's being targeted on the target $ref.

Does that make sense / is that what you were thinking?

Assuming plan is to consider improvements to the path reporting stuff in a separate PR, this looks good to me 👍.
