What build environments should Cabal support?
by Ben Millwood 14 Dec '12

14 Dec '12

I recently submitted a pull request to Cabal to remove a block of code that lived inside a CPP conditional, that I suspect had not been compiled for years: https://github.com/haskell/cabal/pull/1148 I think it would be beneficial if we came up with a policy that allowed us to prune code like this more thoroughly: a clear statement of what libraries and compilers, at what versions, we intend Cabal to be used with. The situation we have at the moment is one where someone bumps a library version in one place, dropping support for some setup in the name of simplicity, but because there is no universal policy, other code to take care of that setup may remain. Code like the stuff I removed continues to exist in a state of limbo, and it is highly likely that when changes are made that break it, no-one will notice, since no-one is testing on that setup anymore. The result is a far more confusing and intricate scattering of CPPery than any of us want to deal with. The README still contains advice for users of GHC 6.4.1. I think it would be wise to bin that and replace it with a more explicit statement of exactly which targets we are programming to. Key questions we need to answer are: - what is the oldest version of GHC we intend to support? - do we still support Hugs? what about other non-GHC implementations?

Status update on sandboxed builds
by Johan Tibell 10 Dec '12

10 Dec '12

Hi all, I thought I'd give everyone a status update on the sandboxed build support. Mikhail has been busy at work implementing automatic rebuilding of local dependencies. Local dependencies let you can build one unreleased package against another unreleased package, both residing in e.g. ~/src. This is similar to cabal-dev's add-source feature, but instead of installing a snapshot of a local package when the command is run we create a link to the package and rebuild it when needed. This means that you will be able to do something like this: cd proj cabal add-source ~/src/dep cabal build -- builds dep and then proj <edit ~/src/dep> cabal build -- builds dep and then proj This will make it much easier working with collections of libraries. What remains to be done: * Implement the UI described here: http://hackage.haskell.org/trac/hackage/wiki/PackageEnvironments#Userinterf… . This is mostly done already. We need to merge the current hidden cabal sandbox-* commands (e.g. cabal sandbox-build) into their standard variants (e.g. cabal build). * Lots of testing! Cheers, Johan

Gearing up for a cabal-install-1.16.0 release
by Johan Tibell 03 Dec '12

03 Dec '12

Hi all, There's been a long time since we had a cabal-install release and there are a lot of bug fixes in the repo we need to get out there. After discussing with Duncan we agreed that the cabal-install release should depend on the already released Cabal-1.16.0 package. I've created a new branch, cabal-install-1.16.0, for making the cabal-install-1.16.0 release. The branch was made from the point in the history where Cabal-1.16 was released. There were some patches on the cabal-1.16 branch that never made it into the Cabal-1.16 release. If there are any commits on the cabal-1.16 branch that you think should definitely be in cabal-install-1.16.0, please let me know and I will try to cherry-pick them. Here's the list of commits: https://github.com/haskell/cabal/compare/cabal-install-1.16.0...cabal-1.16 N.B. Commits that require unreleased changes to the Cabal library cannot be cherry-picked into this release, as we're not making a new release of Cabal the library. P.S. There will be more Cabal/cabal-install releases in the future so lets not try to cram unnecessary stuff in this release. The goal is to get almost a year's worth of unreleased stuff out there in a non-eventful manner. Cheers, Johan
