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.

Eelco Dolstra 135b7d54db * Don't check for staleness by default. 2003-07-13 21:43:57 +00:00
Eelco Dolstra e6363b05ae * Pass $(prefix) and other variables through -D..., not
through config.h, to prevent silly Autoconf problems.

Eelco Dolstra 9c620e4afa * Generate the scripts so that we can substitute the prefix
etc. correctly.
* Fixed nix-switch.
2003-07-13 18:58:03 +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).
2003-07-11 08:41:03 +00:00
Eelco Dolstra c834a5c597 * Fix handling of pipes (read(2) may not return the required
number of bytes in one call).

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 2b95a9dc05 * When computing the set of paths referenced by an expression, also
include the paths of the subterms.
2003-07-09 15:02:03 +00:00
Eelco Dolstra 9a99dc736d * Canonicalise paths so that Fix produces identical Nix
expressions for identical inputs.
2003-07-08 20:26:22 +00:00
Eelco Dolstra 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.

Eelco Dolstra 333f4963de * The output of a Derive() node is not a referenced path. 2003-07-08 15:33:06 +00:00
