Cabal: source-repository-package breaks 'cabal new-install all'

[hasufell]

Example minimal project: https://github.com/hasufell/example-cabal-project

$ cabal new-install all
Wrote tarball sdist to
/home/maerwald/git/example-cabal-project/dist-newstyle/sdist/example-cabal-project-0.1.0.0.tar.gz
cabal: The impossible happened: a local package isn't local

And cabal new-install on the contrary does nothing.

[fgaz]

Another dup of #5586?

[hasufell]

I don't think it's a dup, new-install is completely broken, it doesn't install those dependencies either.

[hvr]

@hasufell but do you expect new-install to treat the source-repo deps as if they were local packages and thus their executables to be installed by new-install? or should they rather be treated as dependencies (and thus their executables not be installed)?

[hasufell]

Imo, those are dependencies.

[hvr]

Another way to trigger the same exception:

1. cabal.project file with only

packages: http://hackage.haskell.org/package/uhttpc-0.1.1.0/uhttpc-0.1.1.0.tar.gz
allow-newer: uhttpc:*

2.

$ cabal new-install uhttpc -v
