The reduced 'darcs' derivation is supposed to be run-time independent of the
Haskell compiler. Unfortunately, this isn't quite true yet because the HTTP
package bakes its own store path into the library. This causes Darcs -- which
links the HTTP library statically -- to depend on 'HTTP', which in turn depends
on lot of other Haskell stuff. Patching HTTP to get rid of that reference looks
feasible, though.
It doesn't run very well with our symlinks in PATH, but I don't know what
patch can make it work still. This is better than nothing; calling it
with its full path makes it work.
This set of packages for Plone was generated using
cillianderoiste/python2nix, which is forked from garbase/python2nix.
It uses ```buildout annotate``` to dump a set of packages and their
versions based on an installed Plone instance and then looks up these
packages on pypi, gets the relevant download url and sets some
(minimal) buildInputs where required.
The packages are not ready to be used on their own yet, since they
lack complete dependencies. In the future we can move complete package
expressions into a better location so that they can be re-used.
The packages are also lacking metadata. They are all available under
Free licenses (mostly Zope Public License, GPL or BSD), but the script
does not yet fill that information in. It should be pretty easy to get
hold of it, plus the short description and home page from pypi, this
will be added to the script in the future so that the license
information is accurate.
(and from Hydra). It is still possible to install any of those packages by
referring to them by attribute:
| $ nix-env -iA haskellPackages_ghc6104.hopenssl --dry-run
| (dry run; not doing anything)
| installing `haskell-hopenssl-ghc6.10.4-1.6.1'
| these paths will be fetched (50.61 MiB download, 450.34 MiB unpacked):
| /nix/store/rjsgga1fdqin47n2rkfn9l7v9ncsfh9l-haskell-hopenssl-ghc6.10.4-1.6.1
| /nix/store/y567qhqbjxbkldg3kq2clzn52a56cmdn-haskell-mtl-ghc6.10.4-1.1.0.2
| /nix/store/zbn24z1443fbrx6ch1nn2vnss9bdw1g0-ghc-6.10.4
It's no longer possible to install those by name anymore, though:
| $ nix-env -i haskell-hopenssl-ghc6.10.4
| error: selector `haskell-hopenssl-ghc6.10.4' matches no derivations
That style works only for active GHC versions 7.4.2 and 7.6.2:
| $ nix-env -qaP \* | grep haskell-hopenssl
| haskellPackages.hopenssl haskell-hopenssl-ghc7.4.2-1.6.1
| haskellPackages_ghc742_no_profiling.hopenssl haskell-hopenssl-ghc7.4.2-1.6.1
| haskellPackages_ghc742_profiling.hopenssl haskell-hopenssl-ghc7.4.2-1.6.1-profiling
| haskellPackages_ghc762.hopenssl haskell-hopenssl-ghc7.6.2-1.6.1
These changes intend to ease the load on Hydra. If you desperately need
pre-build binaries of any of those old versions, please post a short note
on the nix-dev mailing list.
