[Haskell-cafe] Changes to cabal-install

[Amy de Buitléir]

I have a couple of questions about the latest cabal-install release, and I
haven't been able to find the release notes (checked GitHub, the Haskell.org
wiki, googled, etc.) Here's what I'm running:

amy at wombat$ cabal --version
cabal-install version 1.18.0.3
using version 1.18.1.3 of the Cabal library


Question 1
----------
Until recently, the command

    cabal install --enable-tests

used to build and run the tests. Now it seems I need to do

    cabal test

which then compiles the tests and runs them. So is the --enable-tests flag
doing anything, or is it now obsolete?


Question 2
----------
With my project, I do, in order:

1. cabal sandbox init --sandbox <directory>
2. cabal install --only-dependencies
3. cabal build --ghc-options=-Werror
4. cabal test

But when I do step 3, I get a strange warning message: "The sandbox was
created after the package was already configured." Huh? Creating the sandbox
was the first thing I did!

If instead, I replace step 3 with

3. cabal install --ghc-options=-Werror

then I don't get the warning message until step 4.
