Segfault (infinite recursion?) when loading YAML schema into Box with `box_dots=True`

[brynpickering]

I have a YAML schema (see here) which I want to be able to get the flattened dict keys for - something that Box is well placed to provide with its dot notation.

However, I get a segfault when loading the YAML file with:

from box import Box
schema = Box.from_yaml("path/to/schema.yaml", default_box=True, box_dots=True)

It loads successfully with:

from box import Box
schema = Box.from_yaml("path/to/schema.yaml")

But then I lose the ability to inspect the flattened keys (schema.keys(dotted=True)).

Confirmed with that file the behavior, with both ruamel.yaml and pyyaml as backends, so is from something in my code side looping. Thanks for raising the issue will look into!

Anything new on this one? I have a similar problem but with some JSON:

Box.from_yaml(resp.text, box_dots=True)

I am pretty sure Box chokes on / or . in the... keys maybe?

@paulschroeder-tomtom good find, yes.

If there are keys with . or [] in them, box dots will treat them as if they should break them apart.

For example in @brynpickering YAML has keys like '^[^_^\d][\w]*$': {} that it will fail on.

I don't see any what Box could really support those cases, but should at least have a check on box creation if something is going to break it like that and give a clear error.

Ok, I sad but then it is like that. WIll you create an improve on the error message?
