Eelco Dolstra 991a130b1e * Added a list concatenation operator: 
[1 2 3] ++ [4 5 6] => [1 2 3 4 5 6]
 2005-07-25 15:05:34 +00:00
Eelco Dolstra 4c20a08293 * Build dynamic libraries. 2005-07-22 14:52:45 +00:00
Eelco Dolstra 0f827cc607 * Prevent repeated wrapping of closed terms 
(closed(closed(closed(...)))) since this reduces performance by
  producing bigger terms and killing caching (which incidentally also
  prevents useful infinite recursion detection).

Eelco Dolstra 2135e7c041 * Wat cleanups. 2005-07-16 23:19:20 +00:00
Eelco Dolstra 6f82a78de7 * Define paths using regexps, as is done in the Flex definition. 2005-07-16 21:38:15 +00:00
Eelco Dolstra 6f91f02f75 * Make the rejects a bit more compact. 
* Add lexical restrictions for keywords.

Eelco Dolstra 9590009a74 * Fix ambiguity. 2005-07-16 15:41:27 +00:00
Eelco Dolstra f797cb5855 * Revive and update the SDF grammar for Nix expressions. 2005-07-16 14:07:35 +00:00
Eelco Dolstra 22d3587f3b * In nix-instantiate, at top-level, call functions that have arguments 
with default values automatically.  I.e., e -> e {}.

  This feature makes convenience expressions such as
  pkgs/system/i686-linux.nix in Nixpkgs obsolete, since we can just do

  $ nix-instantiate ./pkgs/system/all-packages.nix

  since all-packages.nix takes a single argument (system) that has a
  default value (__thisSystem).

Eelco Dolstra 040140dd1c * Added a primop `removeAttrs' to remove attributes from a set, e.g., 
`removeAttrs attrs ["x", "y"]' returns the set `attrs' with the
  attributes named `x' and `y' removed.  It is not an error for the
  named attributes to be missing from the input set.

Eelco Dolstra 109cde6706 * Ignore (with a warning) invalid garbage collector roots. 2005-05-10 14:56:10 +00:00

Eelco Dolstra 9ec7e58aa4 * Handle store path arguments in `nix-env -i' correctly again. 2005-05-09 17:55:35 +00:00
Eelco Dolstra 8f57634c14 * Automatically upgrade the Berkeley DB environment if necessary. 2005-05-09 15:25:47 +00:00
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 6057b51835 * Don't try to register GC roots in read-only mode. 2005-05-07 21:33:31 +00:00
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 02f2da0142 * Merging from nix-make branch: 
- Add __currentTime primitive (dangerous!).
  - Allow imports of derivations.
 2005-05-02 14:44:58 +00:00
Eelco Dolstra f913283570 * Remove redundant message. 2005-04-13 09:20:27 +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 cab7816b56 * Slightly nicer message. 2005-04-11 08:07:41 +00:00
Eelco Dolstra c9c58dba55 * Primop `__currentSystem' to return the current platform identifier. 2005-04-10 17:38:19 +00:00
Eelco Dolstra c702dfca3f * nix-store: --substitute' -> --register-substitutes'. 2005-04-08 13:48:41 +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 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'.
 2005-04-07 14:01:51 +00:00

Eelco Dolstra 298dd487bb * When finding live paths, the deriver need not be valid. 2005-03-25 14:31:12 +00:00
Eelco Dolstra 7eaf038763 * `nix-store --verify': repair bad referer mappings. 2005-03-25 14:21:49 +00:00
Eelco Dolstra c6178f0b03 * Create missing log and temproots directories automatically (reported 
by Rob).
 2005-03-24 17:46:38 +00:00
Eelco Dolstra cff6bc06df * Fix endianness bug. 2005-03-23 19:18:22 +00:00
Eelco Dolstra 0df9f08078 * Export the references graph to the build hook. 2005-03-23 13:16:36 +00:00
Eelco Dolstra 3f236f01ae * `nix-store --register-validity': allow a path to refer to a path 
listed later in the list of new valid paths.
 2005-03-23 13:07:28 +00:00
Eelco Dolstra a04c62e0c4 * Canonicalise path meta-data in `nix-store --register-validity'. 2005-03-23 12:06:57 +00:00
Eelco Dolstra f20f081560 * nix-store: --isvalid' -> --check-validity', `--validpath' -> 
`--register-validity'.
* `nix-store --register-validity': read arguments from stdin, and
  allow the references and deriver to be set.
 2005-03-23 11:25:20 +00:00
Eelco Dolstra c757d16c8c * Bug in clearSubstitutes(). 2005-03-14 18:54:40 +00:00
Eelco Dolstra 08df443618 * Check for duplicate attributes and formal parameters in Nix 
expressions.
 2005-03-10 11:33:46 +00:00
Eelco Dolstra 4bbdcfbb45 * Don't use fork() in copyPath(), but a string buffer. 2005-03-03 13:58:02 +00:00
Eelco Dolstra 86cb3cc554 * Increase Berkeley DB limits a bit more. 
* Maintain the cleanup invariant in clearSubstitutes().
 2005-03-03 13:10:44 +00:00
Eelco Dolstra 07b4399fb6 * `nix-store -q --hash' to quickly query the hash of the contents of a 
store path (which is stored in the database).
 2005-03-02 15:57:06 +00:00
Eelco Dolstra bfaf83a0fd * When multiple derivations are specified in `nix-store -r', don't 
continue building when one fails unless `--keep-going' is
  specified.
* When `--keep-going' is specified, print out the set of failing
  derivations at the end (otherwise it can be hard to find out which
  failed).
 2005-02-23 11:19:27 +00:00
Eelco Dolstra 3a2c3f0cf2 * Support for fixed-output hashes over directory trees (i.e., over the 
NAR dump of the path).
