7b3f44e05b * The new normaliser now passes the unit tests. 2003-07-15 21:24:05 +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.

8898e86b4f * Get the garbage collector to work again. 2003-07-14 10:45:04 +00:00
Eelco Dolstra
3509299aca * After building, scan for actual file system references as
opposed to declared references.  This prunes the reference
  graph, thus allowing better garbage collection and more
  efficient derivate distribution.

e6363b05ae * Pass $(prefix) and other variables through -D..., not
through config.h, to prevent silly Autoconf problems.

etc. correctly.
* Fixed nix-switch.

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).

c834a5c597 * Fix handling of pipes (read(2) may not return the required
number of bytes in one call).

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.

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.

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.

expressions for identical inputs.

cab3f4977a * A path canonicaliser that doesn't depend on the existence of paths
(i.e., it doesn't use realpath(3), which is broken in any case).
  Therefore it doesn't resolve symlinks.
