Thanks for the patches. I'll take a closer look. One minor issue that's rather unfortunate is that you need a (minor) change to Cabal, not only cabal-install. For practical purposes, we're going to aim for a cabal-install release in the not too distant future, but IMHO it should work with the Cabal version that's shipped with ghc-7.4.1 and not require another upgrade there.
I modified Cabal to avoid code duplication. I didn't know about the upcoming cabal-install release. I'm attaching a new patch bundle that doesn't modify Cabal. (These supersede the last set of patches I sent.) The only difference is a small change in Distribution.Client.Types.
Did you have to adapt the install-plan checker in any way?
Yes. It also needs to respect the constraints, i.e., configure packages with '--enable-tests' as appropriate, or it will complain that the install plan pulls in extra dependencies. -- Thomas Tuegel
