22d3587f3b * In nix-instantiate, at top-level, call functions that have arguments
with default values automatically.  I.e., e -> e {}.

  This feature makes convenience expressions such as
  pkgs/system/i686-linux.nix in Nixpkgs obsolete, since we can just do

  $ nix-instantiate ./pkgs/system/all-packages.nix

  since all-packages.nix takes a single argument (system) that has a
  default value (__thisSystem).

040140dd1c * Added a primop `removeAttrs' to remove attributes from a set, e.g.,
`removeAttrs attrs ["x", "y"]' returns the set `attrs' with the
  attributes named `x' and `y' removed.  It is not an error for the
  named attributes to be missing from the input set.

edd145d2fb * Lazily compute the derivation and output paths of derivations. This
makes most query and installation operations much faster (e.g.,
  `nix-env -qa' on the current Nixpkgs is about 10 times faster).

* Make the `derivation' primitive much more lazy.  The expression
  `derivation attrs' now evaluates to (essentially)

    attrs // {
      type = "derivation";
      outPath = derivation! attrs;
      drvPath = derivation! attrs;
    }

  where `derivation!' is a primop that does the actual derivation
  instantiation (i.e., it does what `derivation' used to do).  The
  advantage is that it allows commands such as `nix-env -qa' and
  `nix-env -i' to be much faster since they no longer need to
  instantiate all derivations, just the `name' attribute.  (However,
  `nix-env' doesn't yet take advantage of this since it still always
  evaluates the `outPath' and `drvPath' attributes).

  Also, this allows derivations to cyclically reference each other,
  for example,

    webServer = derivation {
      ...
      hostName = "svn.cs.uu.nl";
      services = [svnService];
    };

    svnService = derivation {
      ...
      hostName = webServer.hostName;
    };

  Previously, this would yield a black hole (infinite recursion).

c815aff21b * `nix-store --add-fixed' to preload the outputs of fixed-output
derivations.  This is mostly to simplify the implementation of
  nix-prefetch-{url, svn}, which now work properly in setuid
  installations.

* Enforce valid store names in `nix-store --add / --add-fixed'.

bfaf83a0fd * When multiple derivations are specified in `nix-store -r', don't
continue building when one fails unless `--keep-going' is
  specified.
* When `--keep-going' is specified, print out the set of failing
  derivations at the end (otherwise it can be hard to find out which
  failed).

eda2c3c253 * Compatibility hack so that Nixpkgs can continue to do hash checking
in `fetchurl' in Nix <= 0.7, but doesn't in Nix 0.8.

3c1630131e * Subtle bug in the builder: if a subgoal that is instantiated
multiple times is also a top-level goal, then the second and later
  instantiations would never be created because there would be a
  stable pointer to the first one that would keep it alive in the
  WeakGoalMap.
* Some tracing code for debugging this kind of problem.

e0181f56be * `nix-store -q --tree' shows a tree representing the dependency graph
of the given derivation.  Useful for getting a quick overview of how
  something was built.  E.g., to find out how the `baffle' program in
  your user environment was built, you can do

    $ nix-store -q --tree $(nix-store -qd $(which baffle))

  Tree nesting depth is minimised (?) by topologically sorting paths
  under the relation A < B iff A \in closure(B).

e17910cfb5 * And yet another installation source: the ability to copy user
environment elements from one user environment to another, e.g.,

    $ nix-env -i --from-profile /nix/var/nix/profiles/other-profile aterm
    
  copies the `aterm' component installed in the `other-profile' to the
  user's current profile.
