Eelco Dolstra 4a013962bd * Started using Berkeley DB environments. This is necessary for
transaction support (but we don't actually use transactions yet).
2003-07-31 13:47:13 +00:00
Eelco Dolstra 5acb45446e * Let `nix --install' print out the id of the normal form.
* Some minor refactoring.
2003-07-29 09:45:03 +00:00
Eelco Dolstra 1a7468a57a * Debug levels. Use `--verbose / -v LEVEL' to display only messages
up to the given verbosity levels.  These currently are:

    lvlError = 0, 
    lvlNormal = 5,
    lvlDebug = 10,
    lvlDebugMore = 15

  although only lvlError and lvlDebug are actually used right now.

Eelco Dolstra 401452e57a * Memoize the evaluation of Fix expressions to speed up computation. 2003-07-21 08:55:49 +00:00
Eelco Dolstra 7984cfc7c1 * Argh, another short-write problem. Added wrappers around
read()/write() to fix this once and for all.

Eelco Dolstra 6f1a0f948d * Refactorings. 2003-07-20 19:29:38 +00:00
Eelco Dolstra 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.

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 5895c160c4 * Make dbRefs a mapping from Hash to [Path]. 2003-07-07 09:25:26 +00:00
