We're pretty well along the way to getting cabal-install and friends

I added a few more. We have 32 now.


Let's imagine something that would be awesome.  A set of Haskell
packages which are all known to work together with a particular
version of cabal (the one that GHC comes with), and a particular
version of GHC.

GHC version 6.6 will be released soon, and I think we should try to
make this happen.

Currently, we have a set of 27 unstable packages.  They may or may
not work with each-other and such:

http://hackage.haskell.org/packages/

I just created an empty directory testing.  I propose that we start
testing packages, starting with the cabal release candidate that'll go
into GHC 6.6, and make sure they work nicely together.  Once they're
known to work, we can migrate them from the unstable directory to
the testing directory.

Once we have a sufficient collection of packages, and once ghc 6.6 is
released, we can make a snapshot of this directory, call it
stable-6.6 or something.  Then if you have ghc 6.6 and
cabal-install, you should be able to cabal-install p for any
package, and it'll definitely work.


What about the packages that have external dependencies? They won't
necessarily be buildable on the server.


So what will we need for this to happen?

1. An installed version of ghc 6.6 on the hackage/darcs server.  Maybe
   in a chroot or something.  Maybe from the nightly build tree or the
   previous snapshot?

2. Some initial set of packages (maybe just cabal-install) to start
   off.

3. Some script that goes through and builds all of the unstable
   packages in dependency order.  I think cabal-install can do this
   already.  In fact, it would be ideal if we used cabal-install for
   this.

4. The script should also run ./setup haddock and ./setup test.  If
   the packages seem to work w/ 6.6 and the other packages in
   testing, it should get migrated from unstable to testing.

5. A web interface (lemmih is working on it)


HackageDB is as good as it's gonna get for now. Btw, why is this step necessary?


6. A script to upload packages to unstable (Paolo is working on it).

7. Someone to spearhead all of this!


I have time. However, I also see a lot of problems.

I'd like to trim the followup to cabal-devel@ or libraries@ so we
don't cross-post to all lists.

Cool!

That's true.  For such packages, we could install their dependencies
by hand.  Or we could exclude them as being too outside the system.  I
think an automagic solution for this problem is beyond the scope of
cabal/hackage.

 5. A web interface (lemmih is working on it)

 HackageDB is as good as it's gonna get for now. Btw, why is this
 step necessary?

The web interface is important for both the unstable and stable
collections.  People need to be able to look at what's available on
the server.  People need to know where to go for the authoritative
release of packages.

Simon Peyton Jones also happens to think that a web interface that
shows all of the packages is very important.  Maybe he can go into
some detail about why.

Would anyone else like to take up hacking on the web interface?
