Stack: Cut a new release version - (v1.6.6 or v1.7)

[recursion-ninja]

I've been waiting to use features added to Cabal-2.2.* in conjunction with stack for a month now. Unfortunately there's been no traction on the three issues listed as blocking release (#3796, #3791, #3782).

Specifically I need to use the cxx-options and cxx-sources buildinfo fields for separate compilation of C and C++ source files. stack's lack of support of these features is roadblocking our development and continuous integration efforts.

Could you prioritize resolving issues blocking a release incorporating Cabal-2.2.*?

[borsboom]

We're hoping to release 1.7 soon, so I've asked @mgsloan about the priotiy on those issues. The Cabal-2.2 changes are too big to backport to 1.6, so it'll have to be a new major release.

[recursion-ninja]

I'm glad to hear the new release is coming soon. Is there a time table for the v1.7 release somewhere or is that still being determined?

[davetapley]

Looks like #3791 was the sole remaining P0: Blocking release issue, and AFAICT the fix has been merged (#3795). Is my hope merited?

[recursion-ninja]

@dukedave I think so! I'm sure there's a bit a of a review process in tagging a new release, something I'm unfamiliar with. I'm hoping the Stack team can make progress on that next week!

Release candidate for v1.7.1: https://github.com/commercialhaskell/stack/releases/tag/v1.7.0.1

[recursion-ninja]

@borsboom I tried to build this minimum working example test repository that requires the cxx-sources & cxx-options flags with the v1.7.0.1 pre-release version. Unfortunately it didn't correctly build.

I ran the following commands:

cabal --version
stack-1.7.0.1 init
stack-1.7.0.1 build

I got the following output:

There were a lot of warnings emitted regarding the cxx-sources & cxx-options flags. Also, there was a lot of Cabal-2.0.1.1 in the output. I'm not convinced that it is building using Cabal-2.2.

[borsboom]

tcm-memo.cabal should specify cabal-version: 2.2, otherwise those fields won't be recognized. Although once you do that, your build will fail with:

Cabal-simple_mPHDZzAJ_2.0.1.0_ghc-8.2.2: This package description follows
version 2.2 of the Cabal specification. This tool only supports up to version
2.0.1.0

That's because GHC 8.2.2 comes with Cabal-2.0.1.0 and so that is the version that's used to build your package. Change the resolver in stack.yaml to nightly-2018-04-17, to use GHC 8.4.1, and it should work.

@borsboom thanks for the technical assistance, let me try to rebuild in the morning with ghc-8.4.1.

I did try bumping the cabal-version field to 2.2 but was getting parse errors from cabal with ghc-8.2.2. That consumed my attention and caused me to miss the informative warning message.

[recursion-ninja]

@borsboom the test repository _does build_ with the v1.7.0.1 release candidate after ensuring that the resolver used ghc-8.4.1!
