relax _include_this_registry check

[johnnychen94]

Sometimes one might prefer to use a fork URL for various reasons(e.g., private network, slow connection to GitHub). The current _include_this_registry check fails silently by returning false. This causes some hard to figure error:

# a private URL because connection to GitHub is slow here; one can use any General fork to reproduce this issue
url = "https://gitlab.lflab.cn/julialang/JuliaRegistries/General.git"
RegistryCI.test(registry_deps=[url])

This change introduces a lowercase(basename(x)) alternative and uses the set intersection operation to simplify the logic.

I don't think we should apply this relaxed behavior by default. Perhaps we can provide a keyword argument, and when the user sets this keyword argument to a certain value, then we apply the relaxed behavior, but otherwise we apply the regular behavior.

[GunnarFarneback]

I have no idea what this code is good for. load_registry_dep_uuids creates a temporary depot, installs a couple of registries, then loops over the registries to see if they actually match the list of registries that were just installed? If it were me I would just replace _include_this_registry with true, so I guess I'm missing something vital.

[DilumAluthge]

IIRC, we added _include_this_registry in #367 to fix a bug (#361 (comment)).

[DilumAluthge]

Before #367, instead of _include_this_registry, we had this code:

if spec.url ∈ registry_deps_names || spec.name ∈ registry_deps_names

After #367, that code became:

if _include_this_registry(spec, registry_deps_names)

[GunnarFarneback]

Sorry, I still don't understand why there is an if statement there in the first place.

[ericphanson]

Sorry for the late review, but I agree with Gunnar that it looks like we create a fresh depot, then add the registries the user specifies, so it seems like we could just include them all and not have a check. What could the check filter out?

[DilumAluthge]

Hmmmm..... it's been so long that I don't remember why the code is structured this way.

Should we try changing the if conditional to if true and see if anything breaks?

[ericphanson]

Sure
