4d21cda0cd * Fix for big-endian platforms: check for endianness in MD5 computations.
This is done at runtime, which is inefficient, but I can't be bothered
  to write an Autoconf test right now.

f8d91f20e6 * Nix can now fetch prebuilts (and other files) from the network, iff
a mapping from the hash to a url has been registered through `nix
  regurl'.

* Bug fix in nix: don't pollute stdout when running tar, it made
  nix-switch barf.

* Bug fix in nix-push-prebuilts: don't create a subdirectory on the
  target when rsync'ing.

7dd91d3779 * Prebuilt package sharing. We allow transparent binary deployment by
sharing package directories (i.e., the result of building a Nix
  descriptor).

  `nix-pull-prebuilts' obtains a list of all known prebuilts by
  consulting the paths and URLs specified in
  $prefix/etc/nix/prebuilts.conf.  The mappings ($pkghash,
  $prebuilthash) and ($prebuilthash, $location) are registered with
  Nix so that it can use the prebuilt with hash $prebuilthash when
  installing a package with hash $pkghash by downloading and unpacking
  $location.

  `nix-push-prebuilts' creates prebuilts for all packages for which no
  prebuilt is known to exist.  It can then optionally upload these
  to the network through rsync.

  `nix-[pull|push]-prebuilts' just provide a policy.  Nix provides the
  mechanism through the `nix [export|regprebuilt|regurl]' commands.

0ef4b6d0f8 * Cleaned up the semantics of Fix expressions.
* Conditionals and variables in Fix expressions.  This allows, e.g.,

    Descr(
    [ Bind("pkgId", "subversion-0.21.0")

    , Bind("httpsClient", Bool(True))
    , Bind("httpServer", Bool(True))

    , Bind("ssl", If(Var("httpsClient"), Fix("./openssl-0.9.7b.fix"), ""))

    , Bind("httpd", If(Var("httpServer"), Fix("./httpd-2.0.45.fix"), ""))
    ...
    ])

  which introduces domain feature variables httpsClient and httpServer
  (i.e., whether Subversion is built with https client and webdav
  server support); the values of the variables influences package
  dependencies and the build scripts.

  The next step is to allow that packages can express constraints on
  each other.  E.g., StrategoXT is dependent on an ATerm library with
  the "gcc" variant enabled.  In fact, this may cause several
  Nix instantiations to be created from a single Fix descriptor.  If
  possible, Fix should try to find the least set of instantiations
  that obeys the constraints.

Eelco Dolstra
b762f4df7f * In `fix --instantiate', only print out the hashes of the Nix
descriptors generated out of Fix descriptors specified on the
  command line.  This allows us to say:

    nix-switch $(fix -i ./test/fixdescriptors/system.fix)

aa8fda4b54 * We no longer use nix-populate standalone, rather we use it as a
build action for `system' packages (like system.fix) that have
  dependencies on all packages we want to activate.

  So the command sequence to switch to a new activation configuration
  of the system would be:

    $ fix -i .../fixdescriptors/system.fix
    ...
    system.fix -> 89cf4713b37cc66989304abeb9ea189f

    $ nix-switch 89cf4713b37cc66989304abeb9ea189f

* A nix-profile.sh script that can be included in .bashrc.

Eelco Dolstra
0f40a560ca * Added a script nix-activate which builds a list of "activated"
packages (i.e., the packages that should appear in the user's $PATH,
  and so on).  Based on this list, the script nix-populate creates a
  hierarchy of symlinks to the relevant files in those packages (e.g.,
  for pkg/bin and pkg/lib).  

  A nice property of nix-populate is that on each run it creates a
  *new* tree, rather than updating the old one.  It then atomically
  switches over to the new tree.  This allows atomic upgrades or
  rollbacks on the set of activated packages.

73c53935d0 * For efficiency: md5 integrated into nix.
* Command `nix ensure' which is like `nix getpkg' except that if the
  has refers to a run action it will just ensure that the imports are
  there.
* Command `nix closure' to print out the closure of the set of
  descriptors under the import relation, starting at a set of roots.
  This can be used for garbage collection (e.g., given a list of
  `activated' packages, we can delete all packages not reachable from
  those).
* Command `nix graph' to print out a Dot graph of the dependency
  graph.
* `nix-addroot' adds a root for the (unimplemented) garbage collector.

2dc84e5569 * Descriptors now have a "system" field specifying the platform that
the build or run action should be perfomed on.  This ensures that
  descriptors have different hashes on different platforms.

Eelco Dolstra
20d165c344 * A command to run programs in Nix packages, that is, to execute a run
action.  Run actions are described by uniquely hashed descriptors,
  just like build actions.  Therefore run actions can have
  dependencies, but these need not be the same as the build time
  dependencies (e.g., at runtime we can link against a different
  version of a dynamic library).  Example:

    nix run 31d6bf4c171282367065e0deecd7c579

  will run the Pan 0.13.91 newsreader with gtkspell support.

cadc3852e4 * nix-instantiate now instantiantes the closure of the set of
descriptor templates under the import relation.  I.e., we can now
  say:

    nix-instantiate outdir foo.nix

  which will create descriptors for foo.nix and all imported packages
  in outdir/.

Eelco Dolstra
8999f923ea * Improved Nix. Resources (package descriptors and other source
files) are now referenced using their cryptographic hashes.  

  This ensures that if two package descriptors have the same contents,
  then they describe the same package.  This property is not as
  trivial as it sounds: generally import relations cause this property
  not to hold w.r.t. temporality.  But since imports also use hashes
  to reference other packages, equality follows by induction.
