Make x509-validation.cabal depend less on "IO" and be more pure. #32

Closed alexanderkjeldaas closed 9 years ago

alexanderkjeldaas commented 10 years ago

If I may come with a feature request, it seems that x509-validation.cabal depends on a lot of IO-libraries like filepath, process, network.

I would like to be able to cross-compile the x509 handling to javascript, and thus having a "pure" package would help.

As much as I like cross compilation from hs to javascript, x509 validation requires lots of IO stuff to actually happens (CRL, OSCP, access to system store, ..) so I don't think that's a realistic goal.

alexanderkjeldaas commented 9 years ago

That makes sense. How about wrapping all of that in a few typeclasses? Then instead of using IO you would require that typeclass.

Then there could be three implementations of that typeclass. One mock for testing, one for a javascript implementation, and one which maps to the current implementation.

Come to think of it, many thinks are already in hooks, and I'm happy to accept more hooks to achieve goals to make it more javascript friendly.
