8022015552 * In the garbage collector, don't count files with a link count > 1 in
the "bytes/blocks freed" statistics.

f9e766db98 * Randomise the order in which we delete entries to make the collector
less biased towards deleting paths that come alphabetically first
  (e.g. /nix/store/000...).  This matters when using --max-freed etc.

3d55f1eb57 * A command `nix-store --query --roots <paths>' to find the garbage
collector roots that point (directly or indirectly) to the given
  paths.

ae6bf87273 * `nix-store --gc --print-roots': also print the path of the actual
root symlink, not just its target.  E.g.:

  /nix/var/nix/profiles/system-99-link -> /nix/store/76kwf88657nq7wgk1hx3l1z5q91zb9wd-system

c364d5d1e3 * Made the garbage collector a lot faster. It no longer computes the
complete set of live and dead paths before starting the actual
  deletion, but determines liveness on demand.  I.e. for any path in
  the store, it first tries to delete all the referrers, and then the
  path itself.  This means that the collector can start deleting paths
  almost immediately.

4f7e5f5810 * Don't create /nix/var/nix/gcroots/{tmp,channels}, since they don't
seem to be used anymore.

8824d60fe5 * Remove the --use-atime / --max-atime garbage collector flags. Many
(Linux) machines no longer maintain the atime because it's too
  expensive, and on the machines where --use-atime is useful (like the
  buildfarm), reading the atimes on the entire Nix store takes way too
  much time to make it practical.

Nix though.

3392d32e8b * In nix-pull/nix-channel, create the manifests directory if it
doesn't exist.  The Debian packages don't include the manifests
  directory, so nix-channel would silently skip doing a nix-pull,
  resulting in everything being built from source.  Thanks to Juan
  Pedro Bolívar Puente.

8520542071 * When building in a chroot, make a copy of a file if hard-linking
fails.  This is likely to happen after a `nix-store --optimise',
  because some files may have 32000 links (NIX-111).

deb342fb08 * builtins.trace: in the common case that the value is a string, then
show the string, not the ATerm, so we get `trace: bla' instead of
  `trace: Str("bla",[])'.

18f0ff003d configure.ac: use AC_SYS_LARGEFILE to determine how to enable 64-bit file size support
Defining -D_FILE_OFFSET_BITS=64 works on most platforms, but not on all (i.e.
Solaris). Also, the Autoconf macro offers the user a switch to disable the
functionality in case of problems.

1332dd1ed3 * tryEval shouldn't catch all exceptions of type Error, since not all
of them leave the evaluator in a continuable state.  Also, it should
  be less chatty.

86408b3f47 * build-remote.pl: Pick machines in a round-robin order, rather than
giving jobs to the first machine until it hits its job limit, then
  the second machine and so on.  This should improve utilisation of
  the Hydra build farm a lot.  Also take an optional speed factor
  into account to cause fast machines to be preferred over slower
  machines with a similar load.

57e0d73c77 * build-remote.pl: allow the system type to be a comma-separated list
of system types.  Don't treat the x86_64-linux system type
  specially.

0dbd4638e0 * Two primops: builtins.intersectAttrs and builtins.functionArgs.
intersectAttrs returns the (right-biased) intersection between two
  attribute sets, e.g. every attribute from the second set that also
  exists in the first.  functionArgs returns the set of attributes
  expected by a function.

  The main goal of these is to allow the elimination of most of
  all-packages.nix.  Most package instantiations in all-packages.nix
  have this form:

    foo = import ./foo.nix {
      inherit a b c;
    };

  With intersectAttrs and functionArgs, this can be written as:

    foo = callPackage (import ./foo.nix) { };

  where

   callPackage = f: args:
     f ((builtins.intersectAttrs (builtins.functionArgs f) pkgs) // args);

  I.e., foo.nix is called with all attributes from "pkgs" that it
  actually needs (e.g., pkgs.a, pkgs.b and pkgs.c).  (callPackage can
  do any other generic package-level stuff we might want, such as
  applying makeOverridable.)  Of course, the automatically supplied
  arguments can be overriden if needed, e.g.

    foo = callPackage (import ./foo.nix) {
      c = c_version_2;
    };

  but for the vast majority of packages, this won't be needed.

  The advantages are to reduce the amount of typing needed to add a
  dependency (from three sites to two), and to reduce the number of
  trivial commits to all-packages.nix.  For the former, there have
  been two previous attempts:

    - Use "args: with args;" in the package's function definition.
      This however obscures the actual expected arguments of a
      function, which is very bad.

    - Use "{ arg1, arg2, ... }:" in the package's function definition
      (i.e. use the ellipis "..." to allow arbitrary additional
      arguments), and then call the function with all of "pkgs" as an
      argument.  But this inhibits error detection if you call it with
      an misspelled (or obsolete) argument.
