Eelco Dolstra 8520542071 * When building in a chroot, make a copy of a file if hard-linking
fails.  This is likely to happen after a `nix-store --optimise',
  because some files may have 32000 links (NIX-111).
2009-10-22 08:28:33 +00:00
Eelco Dolstra 6b9f6b0222 * Remove a prototype for a function that no longer exists. 2009-10-22 08:12:38 +00:00
Eelco Dolstra deb342fb08 * builtins.trace: in the common case that the value is a string, then
show the string, not the ATerm, so we get `trace: bla' instead of
  `trace: Str("bla",[])'.

Eelco Dolstra 437077c39d * Added a primop unsafeDiscardOutputDependency needed by Disnix to
pass derivation paths to a builder without actually building them.

Eelco Dolstra 6f7d7bc1de * Give a useful error message when an evaluation error occurs while
trying to upgrade a package.

Sander van der Burg 53a4981fa2 Added optional parameter which adds -lnsl -lsocket to make the Nix package manager work on OpenSolaris 2009-10-08 14:50:37 +00:00
Peter Simons 18f0ff003d configure.ac: use AC_SYS_LARGEFILE to determine how to enable 64-bit file size support
Defining -D_FILE_OFFSET_BITS=64 works on most platforms, but not on all (i.e.
Solaris). Also, the Autoconf macro offers the user a switch to disable the
functionality in case of problems.

Eelco Dolstra 96f1517831 * Support platforms that don't have O_ASYNC (e.g. OpenSolaris
apparently).

Eelco Dolstra 1332dd1ed3 * tryEval shouldn't catch all exceptions of type Error, since not all
of them leave the evaluator in a continuable state.  Also, it should
  be less chatty.

Eelco Dolstra 63a17d4bd5 * Don't build against BDB on Cygwin, it's been broken for unknown
reasons for a while (e.g. http://hydra.nixos.org/build/79164).

Rob Vermaas 48b58617e9 * include wait.h for WEXITSTATUS 2009-09-23 12:57:15 +00:00
Eelco Dolstra 51ad64cc07 * Use xmllint (>= 2.7.4) for RelaxNG validation instead of Jing. 2009-09-18 11:45:56 +00:00
Eelco Dolstra df05a759e4 * In "make init-state", ignore errors creating /nix/store. Hack to
get the Debian VM builds to work (where /nix/store is a mount point
  containing the store of the host).

Eelco Dolstra 86408b3f47 * build-remote.pl: Pick machines in a round-robin order, rather than
giving jobs to the first machine until it hits its job limit, then
  the second machine and so on.  This should improve utilisation of
  the Hydra build farm a lot.  Also take an optional speed factor
  into account to cause fast machines to be preferred over slower
  machines with a similar load.
2009-09-17 15:48:17 +00:00
Eelco Dolstra 57e0d73c77 * build-remote.pl: allow the system type to be a comma-separated list
of system types.  Don't treat the x86_64-linux system type
  specially.

Eelco Dolstra 0dbd4638e0 * Two primops: builtins.intersectAttrs and builtins.functionArgs.
intersectAttrs returns the (right-biased) intersection between two
  attribute sets, e.g. every attribute from the second set that also
  exists in the first.  functionArgs returns the set of attributes
  expected by a function.

  The main goal of these is to allow the elimination of most of
  all-packages.nix.  Most package instantiations in all-packages.nix
  have this form:

    foo = import ./foo.nix {
      inherit a b c;
    };

  With intersectAttrs and functionArgs, this can be written as:

    foo = callPackage (import ./foo.nix) { };

  where

   callPackage = f: args:
     f ((builtins.intersectAttrs (builtins.functionArgs f) pkgs) // args);

  I.e., foo.nix is called with all attributes from "pkgs" that it
  actually needs (e.g., pkgs.a, pkgs.b and pkgs.c).  (callPackage can
  do any other generic package-level stuff we might want, such as
  applying makeOverridable.)  Of course, the automatically supplied
  arguments can be overriden if needed, e.g.

    foo = callPackage (import ./foo.nix) {
      c = c_version_2;
    };

  but for the vast majority of packages, this won't be needed.

  The advantages are to reduce the amount of typing needed to add a
  dependency (from three sites to two), and to reduce the number of
  trivial commits to all-packages.nix.  For the former, there have
  been two previous attempts:

    - Use "args: with args;" in the package's function definition.
      This however obscures the actual expected arguments of a
      function, which is very bad.

    - Use "{ arg1, arg2, ... }:" in the package's function definition
      (i.e. use the ellipis "..." to allow arbitrary additional
      arguments), and then call the function with all of "pkgs" as an
      argument.  But this inhibits error detection if you call it with
      an misspelled (or obsolete) argument.

Michael Raskin 3bca8931e8 Adding tryEval builtin. It allows to catch presence of errors in an expression. 2009-08-25 16:06:46 +00:00

Eelco Dolstra c6890d6b5c * Replace newlines in table output with spaces. 2009-07-02 08:52:12 +00:00
Eelco Dolstra 749dd97a54 * Support integers and lists of strings in meta fields. This is
useful for fields like meta.maintainers, meta.priority (which can be
  a proper integer now) and even meta.license (if there are multiple
  licenses).
2009-06-30 15:53:39 +00:00
Eelco Dolstra f2c3fc5191 * Don't show trace information by default (`--show-trace' to enable).
NixOS evaluation errors in particular look intimidating and
  generally aren't very useful.  Ideally the builtins.throw messages
  should be self-contained.

Eelco Dolstra a2fc3a53ba * Highlight URLs containing "=" properly. 2009-06-18 10:04:14 +00:00
Eelco Dolstra d53603c928 * Attributes names in attrsets can contain dots now. 2009-06-18 09:56:50 +00:00
Eelco Dolstra 14bc3ce3d6 * Canonicalise timestamps in the Nix store to 1 (1970-01-01 00:00:01
UTC) rather than 0 (00:00:00).  1 is a better choice because some
  programs use 0 as a special value.  For instance, the Template
  Toolkit uses a timestamp of 0 to denote the non-existence of a file,
  so it barfs on files in the Nix store (see
  template-toolkit-nix-store.patch in Nixpkgs).  Similarly, Maya 2008
  fails to load script directories with a timestamp of 0 and can't be
  patched because it's closed source.

  This will also shut up those "implausibly old time stamp" GNU tar
  warnings.
2009-06-13 16:30:58 +00:00
Eelco Dolstra f24cf5d303 * nix-build: if nix-instantiate or nix-store fails due to a signal
(e.g. out of memory or a segfault), print an error message.
  Otherwise the user doesn't see anything.

Eelco Dolstra c6cb792d48 2009-05-26 16:32:02 +00:00
Eelco Dolstra a64bbe049e * Change the scoping of "inherit (e) ..." in recs so that the
attributes of the rec are in scope of `e'.  This is useful in
  expressions such as

    rec {
      lib = import ./lib;
      inherit (lib) concatStrings;
    }

  It does change the semantics of expressions such as

    let x = {y = 1;}; in rec { x = {y = 2;}; inherit (x) y; }.y

  This now returns 2 instead of 1.  However, no code in Nixpkgs or
  NixOS seems to rely on the old behaviour.
2009-05-15 13:46:13 +00:00
Eelco Dolstra d407d572fd * Some syntactic sugar for attribute sets: allow {x.y.z = ...;} as a
shorthand for {x = {y = {z = ...;};};}.  This is especially useful
  for NixOS configuration files, e.g.

    {
      services = {
        sshd = {
          enable = true;
          port = 2022;
        };
      };
    }

  can now be written as

    {
      services.sshd.enable = true;
      services.sshd.port = 2022;
    }

  However, it is currently not permitted to write
  
    {
      services.sshd = {enable = true;};
      services.sshd.port = 2022;
    }

  as this is considered a duplicate definition of `services.sshd'.
2009-05-15 12:35:23 +00:00
Eelco Dolstra e42975490f * Check for duplicate attributes in fixAttrs, rather than doing a
separate traversal after parsing.  Likewise, check for duplicate
  pattern variables right away.
2009-05-14 14:29:45 +00:00
Eelco Dolstra 50d11b90ca * Allow unsafe (unspecified) comparisons between attrsets unless
NIX_NO_UNSAFE_EQ is set, for now.
2009-05-12 11:06:24 +00:00
Eelco Dolstra c34e6d71bc * Disallow equality tests between attribute sets. This was always
broken, but now the evaluator checks for it to prevent Nix
  expressions from relying on undefined behaviour.  Equality tests are
  implemented using a shallow pointer equality test between ATerms.
  However, because attribute sets are lazy and contain position
  information, this can give false positives.  For instance,
  previously

    let y = {x = 1;}; in y == y

  evaluated to true, while the equivalent expression

    {x = 1;} == {x = 1;}

  evaluated to false.  So disallow these tests for now.  (Eventually
  we may want to implement deep equality tests for attribute sets,
  like lib.eqStrict.)
  
* Idem: disallow comparisons between functions.

* Implemented deep comparisons of lists.  This had the same problem as
  attribute sets - the elements in the list weren't evaluated.  For
  instance,

    ["xy"] == [("x" + "y")]

  evaluated to false.  Now it works properly.

Eelco Dolstra 83bd320b39 * Build a PDF version of the manual in the tarball job (it's not
included in the tarball though).
2009-05-07 13:12:46 +00:00
Eelco Dolstra f751c2966b * Don't have a bugs section in the manual. Bugs should be kept in the
bug tracker.
2009-05-07 13:11:58 +00:00
Eelco Dolstra 404996ca1f * Produce the manual in the tarball job. 2009-05-07 12:57:04 +00:00
Eelco Dolstra 7660e2a068 * Remove a right recursion that causes the parser to barf on very long
lists.  The comment about ATreverse requiring unbounded stack space
  was unfounded anyway.
