How to enable authorize_virtual_chunk_access for http_store accessing a public url

[groutr]

I'm trying to store references in icechunk to a publicly accessible http dataset. I can write the reference to icechunk fine, but when opening repo as a zarr store and accessing the data, I get an error that I haven't authorized virtual chunk access. I see there are credential classes for the various cloud providers, but how do I signal that no credentials are needed to access an http_store?

Thank you for your question @groutr . There is some reference documentation in Repository.open, but bottom line, when you open the repo you pass something like:

repo = Repository.open(..., authorize_virtual_chunk_access={"https://your-url-to-the-chunks", None})

The reason why we force you to pass that silly last argument is security, we want users to opt-in into letting Icechunk fetch virtual chunks for them.

I see. The wording of the docstring made that confusing to understand. The docstring does not differentiate between None as a dictionary value and None as a keyword value.

Ah we should fix that, I see how it can be very confusing.
