Eelco Dolstra 7d876f8fa7 * Get rid of fetchurl, we don't need it anymore. 2005-04-07 14:35:44 +00:00
Eelco Dolstra 3d1b2101cc * Place manifests in /nix/var/nix/manifests.
* Use the new patch downloader.

Eelco Dolstra 37ee6cef99 * Adapted nix-pull to use the new substitute mechanism. 2004-06-21 09:51:23 +00:00
Eelco Dolstra 21655a70f5 * Channels. These allow you to stay current with an evolving set of
Nix expressions.

  To subscribe to a channel (needs to be done only once):

    nix-channel --add \
      http://catamaran.labs.cs.uu.nl/dist/nix/channels/nixpkgs-unstable

  This just adds the given URL to ~/.nix-channels (which can also be
  edited manually).

  To update from all channels:

    nix-channel --update

  This fetches the latest expressions and pulls cache manifests.  The
  default Nix expression (~/.nix-defexpr) is made to point to the
  conjunction of the expressions downloaded from all channels.

  So to update all installed derivations in the current user
  environment:

    nix-channel --update
    nix-env --upgrade '*'

  If you are really courageous, you can put this in a cronjob or
  something.

  You can subscribe to multiple channels.  It is not entirely clear
  what happens when there are name clashes between derivations from
  different channels.  From nix-env/main.cc it appears that the one
  with the lowest (highest?) hash will be used, which is pretty
  meaningless.

Eelco Dolstra af7e6fe22e * Don't use a hard-coded path. 2003-11-22 21:12:36 +00:00
Eelco Dolstra ab350eafd2 * Generate nar.sh, fetchurl.sh. 2003-07-18 07:42:57 +00:00
Eelco Dolstra 1d1c3691d2 * The policy-free derivate sharing now *almost* works. :-) For any
hash for which no local expansion is available, Nix can execute a
  `substitute' which should produce a path with such a hash.

  This is policy-free since Nix does not in any way specify how the
  substitute should work, i.e., it's an arbitrary (unnormalised)
  fstate expression.  For example, `nix-pull' registers substitutes
  that fetch Nix archives from the network (through `wget') and unpack
  them, but any other method is possible as well.  This is an
  improvement over the old Nix sharing scheme, which had a policy
  (fetching through `wget') built in.

  The sharing scheme doesn't work completely yet because successors
  from fstate rewriting have to be registered on the receiving side.
  Probably the whole successor stuff can be folded up into the
  substitute mechanism; this would be a nice simplification.

Eelco Dolstra d072485d28 * Get `nix-push' working again. It now uses Nix/Fix to create Nix
archives (using the package in corepkgs/nar).
* queryPathByHash -> expandHash, and it takes an argument specifying
  the target path (which may be empty).
* Install the core Fix packages in $prefix/share/fix.  TODO: bootstrap
  Nix and install Nix as a Fix package.
