Eelco Dolstra edd145d2fb * Lazily compute the derivation and output paths of derivations. This 
makes most query and installation operations much faster (e.g.,
  `nix-env -qa' on the current Nixpkgs is about 10 times faster).

Eelco Dolstra 426593162e * ATermMap needs an assignment operator, otherwise we are screwed. 2005-05-08 10:28:19 +00:00
Eelco Dolstra 77557a6f06 Commit 3000! 
* Make the `derivation' primitive much more lazy.  The expression
  `derivation attrs' now evaluates to (essentially)

    attrs // {
      type = "derivation";
      outPath = derivation! attrs;
      drvPath = derivation! attrs;
    }

  where `derivation!' is a primop that does the actual derivation
  instantiation (i.e., it does what `derivation' used to do).  The
  advantage is that it allows commands such as `nix-env -qa' and
  `nix-env -i' to be much faster since they no longer need to
  instantiate all derivations, just the `name' attribute.  (However,
  `nix-env' doesn't yet take advantage of this since it still always
  evaluates the `outPath' and `drvPath' attributes).

  Also, this allows derivations to cyclically reference each other,
  for example,

    webServer = derivation {
      ...
      hostName = "svn.cs.uu.nl";
      services = [svnService];
    };

    svnService = derivation {
      ...
      hostName = webServer.hostName;
    };

  Previously, this would yield a black hole (infinite recursion).

Eelco Dolstra 52a2f41320 * Include some required header files. 2005-05-04 16:33:20 +00:00
Eelco Dolstra 26fd28432d * FreeBSD 4.x doesn't have stdint.h, use inttypes.h instead (which is 
also part of ISO C).
 2005-05-04 16:32:54 +00:00
Eelco Dolstra 5dea0622d1 * Idem (constness fix). 
* `compare' in GCC 2.95 is broken.
 2005-05-04 16:31:49 +00:00
Eelco Dolstra 4a266e35d4 * GCC 2.95 compatibility fix in constness; strangely, I think this 
should not have worked at all.
 2005-05-04 16:31:24 +00:00
Eelco Dolstra d7b3cdbd91 * GCC 2.95 compatibility. Prevents internal compiler error in member 
template friends.
 2005-05-04 16:30:35 +00:00
Eelco Dolstra ae6d9033a1 * The eof() state isn't guaranteed to be set non-lazily. GCC 2.95 
compatibility fix.
 2005-05-04 16:29:44 +00:00
Eelco Dolstra d8a31da1ea * Use $(MAKE)' instead of make' for systems where `make' isn't GNU 
make (such as FreeBSD).
 2005-05-04 16:28:39 +00:00
Eelco Dolstra 36fb29f8f0 * Merge remaining stuff from the nix-make branch. 
* Add support for the creation of shared libraries to `compileC',
  `link', and `makeLibrary'.
* Enable the ATerm library to be made into a shared library.
 2005-05-02 15:25:28 +00:00
Eelco Dolstra 02f2da0142 * Merging from nix-make branch: 
- Add __currentTime primitive (dangerous!).
  - Allow imports of derivations.
 2005-05-02 14:44:58 +00:00
Eelco Dolstra 6842bc9ac4 * Be quiet when untarring a channel file. 2005-05-01 09:36:28 +00:00
Eelco Dolstra f913283570 * Remove redundant message. 2005-04-13 09:20:27 +00:00
Eelco Dolstra 9f3601a36c * Argh! The patch downloader was broken due to the renaming of the 
`--isvalid' flag in nix-store.
 2005-04-12 10:51:38 +00:00
Eelco Dolstra f3660b1c8c * Garbage collector fix: allow deletion of paths that have invalid 
(but substitutable) referers.
 2005-04-12 10:51:00 +00:00
Eelco Dolstra d5219a351a * Damn. Disable the USE heuristic for now, since the deriver in the 
database isn't always in the manifest (so the reference graph cannot
  be reconstructed fully).
 2005-04-12 10:07:02 +00:00
Eelco Dolstra 1d86790910 * Bump the version number to 0.9. 2005-04-11 13:04:54 +00:00

Eelco Dolstra 8b70f138e0 * Lots of manual updates, in particular the new `nix-store --query' 
options were documented, as well as the Nix configuration file.
 2005-04-08 13:00:38 +00:00
Eelco Dolstra 4271385a73 * Make `nix-store --query --tree' work on non-derivations (i.e., on 
any store path).
 2005-04-08 12:57:16 +00:00

Eelco Dolstra 7d876f8fa7 * Get rid of fetchurl, we don't need it anymore. 2005-04-07 14:35:44 +00:00
Eelco Dolstra 10c429c757 * If store paths are specified as sources in Nix expressions, don't 
copy them, but use them directly.
 2005-04-07 14:35:01 +00:00
Eelco Dolstra f9848d4f31 * Support base-32 hash representations. 2005-04-07 14:33:32 +00:00
Eelco Dolstra c815aff21b * `nix-store --add-fixed' to preload the outputs of fixed-output 
derivations.  This is mostly to simplify the implementation of
  nix-prefetch-{url, svn}, which now work properly in setuid
  installations.

* Enforce valid store names in `nix-store --add / --add-fixed'.

by Rob).
 2005-03-24 17:46:38 +00:00
Eelco Dolstra d1487d9015 * This is a better location to keep the blacklist, since it can evolve 
separately from Nix or Nixpkgs.
