https://mikewest.github.io/corpp/ should specify what COEP to set for non-HTTP Dedicated Workers (e.g. data, blob, file, etc.). I think inheriting the owner's COEP makes sense.

Yes, for non-HTTP workers we'll need to inherit. Apologies for the misguided earlier comment.

Does file:// normally inherit? I thought inheritence was usually just for local urls.

file: URLs, at least in Chromium, are not going to support COEP, as they don't have headers (and also they're not loadable (or shouldn't be!) from the web unless you flip command-line flags that warn you against doing terrible things).

I think @perryjiang might have been referring to filesystem: URLs, which are basically the same as blob: for these purposes.

This applies to workers, shared workers, and frames. Given that we're building on secure contexts about:blank, about:srcdoc, and blob: are the relevant cases that (in certain contexts) ought to work. data: should not work (as it's not a secure context).

Does that make sense?

I notice that we currently have a test for data: at html/cross-origin-embedder-policy/data.https.html that Firefox passes whereby it inherits cross-origin embedder policy and enforces it, despite not being a secure context. The alternative is a network error for data: URLs, which I'm not sure is what we want?

@whatwg/cross-origin-isolation please see w3c/webappsec-secure-contexts#69 for some further thoughts on data: URLs.

I created web-platform-tests/wpt#21230 for javascript: URLs and web-platform-tests/wpt#21232 as an investigation as to how javascript: URLs should work (that's for Referrer Policy, but COEP ought to be identical to that imo; unfortunately it wasn't sorted out for Referrer Policy).

What is the latest on this? Perhaps someone could summarize what's left to do, and if there are any open questions? @yutakahirano

Currently we inherit parent's policy but we may change that for blobs, depending on the future resolution of #5198.
