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.

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'.

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.
2009-05-07 11:35:52 +00:00
Eelco Dolstra 52a9ba96f5 * Include the version file. 2009-05-07 11:34:08 +00:00
Eelco Dolstra 6a5599fd01 * Typo. 2009-05-07 11:33:57 +00:00
Michael Raskin 098cb9d233 Add an ftruncate call paired with fallocate to play safe with some FSes (namely, BtrFS fallocate sets file size to allocated size, i.e. multiple of block size) 2009-05-04 08:10:24 +00:00
Eelco Dolstra c710fe540e * Machines of type x86_64-linux can do i686-linux builds. 2009-04-21 12:42:47 +00:00
Eelco Dolstra d5eab2fc82 * Use foreach in a lot of places. 2009-04-21 11:52:16 +00:00
Eelco Dolstra 8f1bf28505 * nix-store --verify: don't bail out if a referenced path is missing.
(It can't fix it though.)
2009-04-21 11:06:27 +00:00
Eelco Dolstra 4e646b0ddb * Fix a few "comparison is always false/true due to limited range of
data type" warnings on 64-bit platforms.  The one in parser.y is
  likely to be a real bug.
2009-04-16 12:03:17 +00:00
Eelco Dolstra 0460ea4c39 * Cleanup. 2009-04-16 09:27:33 +00:00
Eelco Dolstra dfb863f333 * Don't cache transient build hook problems. 2009-04-15 06:25:02 +00:00
Eelco Dolstra 435a93b5d8 * Remove references to __XXX primops. 2009-04-14 13:03:27 +00:00
Eelco Dolstra 8b2a01a8c2 * Release notes. 2009-04-14 12:02:22 +00:00
Eelco Dolstra 50cb6f9782 * Debian packages: use /etc, not /usr/etc. 2009-04-02 08:16:15 +00:00
Eelco Dolstra 351bf658f9 * Do a substitution even if --max-jobs == 0. 2009-03-31 21:14:07 +00:00
Eelco Dolstra cff2b2a13a * Doh! 2009-03-31 15:50:03 +00:00
Eelco Dolstra 160a60d663 2009-03-30 19:35:55 +00:00
Eelco Dolstra 805144b705 * Make the poll interval configurable. 2009-03-30 11:34:03 +00:00
Eelco Dolstra 096affb55b * Update the mtime on the lock file to make it easy to see when a slot
was last used.
2009-03-29 18:40:44 +00:00
Eelco Dolstra cbc1f57b48 * Undocument the "system" option. No sane person would use it :-) 2009-03-29 18:08:32 +00:00
Eelco Dolstra 7377195297 * With `--max-jobs 0', print a nicer error message than "Assertion
`!awake.empty()' failed."
2009-03-29 18:06:00 +00:00
Eelco Dolstra 737423a89c * Use polling to wait for a remote build slot when using a build hook
(that is, call the build hook with a certain interval until it
  accepts the build).
* build-remote.pl was totally broken: for all system types other than
  the local system type, it would send all builds to the *first*
  machine of the appropriate type.
2009-03-29 18:00:45 +00:00
Eelco Dolstra 47706e3924 * nix-copy-closure: compute the closure in one call to nix-store,
which is much faster.
2009-03-28 21:10:29 +00:00
Eelco Dolstra 6e946c8e72 * Scan for references and compute the SHA-256 hash of the output in
one pass.  This halves the amount of I/O.
2009-03-28 20:51:33 +00:00
Eelco Dolstra c7152c8f97 * Don't use the non-standard __gnu_cxx::stdio_filebuf class. 2009-03-28 19:41:53 +00:00
Eelco Dolstra 3a2bbe7f8a * Simplify communication with the hook a bit (don't use file
descriptors 3/4, just use stdin/stderr).
2009-03-28 19:29:55 +00:00
Eelco Dolstra 7fb548aa26 * Clean up the output a bit. 2009-03-28 16:12:46 +00:00
Eelco Dolstra f54e800366 * The `fixedOutput' variable didn't get initialised when using a build
hook, causing negative caching to fail randomly.
2009-03-28 16:12:27 +00:00
Eelco Dolstra 38f98b3282 * Argh, stupid timing sensitive tests... 2009-03-27 22:40:22 +00:00
Eelco Dolstra e23a7a8b7b * Debian 5.0, Ubuntu 8.10 builds. 2009-03-27 14:20:03 +00:00
Eelco Dolstra cb85bc396e * Create /nix/store if it doesn't exist. 2009-03-27 14:19:04 +00:00
Eelco Dolstra 61686926d1 * A job for creating a fully statically linked binary tarball. 2009-03-26 14:12:42 +00:00
Eelco Dolstra 9856efc7b0 * Support doing a fully static build. Statically linked Nix binaries
will be useful as a fallback on platforms for which there are no
  RPMs/Debs available.
2009-03-26 12:22:08 +00:00
Eelco Dolstra 5dd8fb2069 * Don't use ULLONG_MAX in maxFreed - use 0 to mean "no limit".
18446744073709551615ULL breaks on GCC 3.3.6 (`integer constant is
  too large for "long" type').
2009-03-26 11:02:07 +00:00
Eelco Dolstra 92f525ecf4 * Negative caching, i.e. caching of build failures. Disabled by
default.  This is mostly useful for Hydra.
2009-03-25 21:05:42 +00:00
Eelco Dolstra 7024a1ef07 * Removed the locking.sh test; it's redundant because of the extended
parallel.sh test.  Also, don't call multiple nix-builds in parallel,
  since they can race creating .nix-build-tmp-derivation.
2009-03-25 16:43:38 +00:00
Eelco Dolstra 8146a0c731 * Use bash in the tests. 2009-03-25 16:11:04 +00:00
Eelco Dolstra a046858a22 * Doh. 2009-03-24 23:40:24 +00:00
Eelco Dolstra 12c8c64efa 2009-03-24 14:07:37 +00:00
Eelco Dolstra 7aedcf9460 * Make this test a bit more robust. It's still timing dependent
though.
2009-03-23 15:16:36 +00:00
Eelco Dolstra 3a87163b24 * Shut up a GCC warning. 2009-03-23 13:52:52 +00:00
