Eelco Dolstra 9d56ca219f * Substitute fixes. 2003-07-16 20:00:51 +00:00
Eelco Dolstra f5b6fa5256 * Basic work on allowing derive expressions to build multiple paths.
This is not entirely trivial since this introduces the possibility
  of mutual recursion.
* Made normal forms self-contained.
* Use unique ids, not content hashes, for content referencing.

Eelco Dolstra 135b7d54db * Don't check for staleness by default. 2003-07-13 21:43:57 +00:00
Eelco Dolstra 73b163c1a1 * Fix a bug that caused Fix not to be deterministic (due to addToStore
returning different paths if the hash of the path to be added was
  already available in the store under a different name).

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 6011bd0da2 * Outline of the new scheme for derivate distribution. 2003-07-09 16:12:40 +00:00
Eelco Dolstra 9a99dc736d * Canonicalise paths so that Fix produces identical Nix
expressions for identical inputs.

Eelco Dolstra 0b38b43bab * deletePath() now removes the path from the hash2paths mapping. 2003-07-08 09:54:47 +00:00
Eelco Dolstra a5a90f501e * Get rid of the `netsources' database.
* Rename the `refs' database to `hash2paths'.
