Eelco Dolstra e5fbf58041 * A command to register successor fstate expressions.
Unifying substitutes and successors isn't very feasible for now,
  since substitutes are only used when no path with a certain is
  known.  Therefore, a normal form of some expression stored as a
  substitute would not be used unless the expression itself was
  missing.

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.

Eelco Dolstra 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.
2003-05-26 09:44:18 +00:00
Eelco Dolstra 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.

Eelco Dolstra 0d2b24cdd1 * `Fix' is a high-level descriptor instantiator for Nix. It replaces
nix-instantiate.

Eelco Dolstra 383f9bb0f1 * Use ATerms for Nix descriptors. 2003-04-01 14:00:47 +00:00
Eelco Dolstra 278ea4097e * Don't fork in `nix run'. 2003-03-28 10:33:34 +00:00
Eelco Dolstra f915f77349 * Allow arguments to be passed to programs in `nix run'. 2003-03-28 09:53:22 +00:00
Eelco Dolstra 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.
2003-03-24 17:49:56 +00:00
Eelco Dolstra 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 9d2f128252 * Refactoring. 2003-03-24 11:50:20 +00:00
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.

Eelco Dolstra 2e59698b78 * Added a command to verify the consistency of the database. 2003-03-21 15:53:35 +00:00
Eelco Dolstra f7a98e081d * Various updates. 2003-03-20 16:53:00 +00:00
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.
