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 351bf658f9 * Do a substitution even if --max-jobs == 0. 2009-03-31 21:14:07 +00:00
Eelco Dolstra 805144b705 * Make the poll interval configurable. 2009-03-30 11:34:03 +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 38f98b3282 * Argh, stupid timing sensitive tests... 2009-03-27 22:40:22 +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 7aedcf9460 * Make this test a bit more robust. It's still timing dependent
though.
2009-03-23 15:16:36 +00:00
Eelco Dolstra d7b2d11255 * Test case (currently fails): multiple Nix builds shouldn't block
waiting on the same lock when there are other builds that can be
  done.
2009-03-22 23:16:18 +00:00
Eelco Dolstra 2897286487 * Unify exportReferencesGraph and exportBuildReferencesGraph, and make
sure that it works as expected when you pass it a derivation.  That
  is, we have to make sure that all build-time dependencies are built,
  and that they are all in the input closure (otherwise remote builds
  might fail, for example).  This is ensured at instantiation time by
  adding all derivations and their sources to inputDrvs and inputSrcs.
2009-03-18 17:36:42 +00:00
Eelco Dolstra e530e0a350 * Improve the test. 2009-03-18 16:36:13 +00:00
Eelco Dolstra 9485ec31ea * Better cleanup after tests. 2009-03-18 16:35:35 +00:00
Eelco Dolstra 13df3915ef * Missing file. 2009-03-18 16:23:29 +00:00
Eelco Dolstra c183ee5c79 * Acquire the locks on the output paths before trying to run the build
hook.  This fixes a problem with log files being partially or
  completely filled with 0's because another nix-store process
  truncates the log file.  It should also be more efficient.
2009-03-18 14:48:42 +00:00
Eelco Dolstra 1dcf208f56 * Clean up some tests (use nix-build where appropriate). 2009-03-18 13:15:55 +00:00
Eelco Dolstra 93b6926054 * Regression test for exportBuildReferencesGraph. It currently fails. 2009-03-17 17:38:32 +00:00
Eelco Dolstra 51e7e32c3b * Refactoring: renamed *.nix.in to *.nix. 2009-03-17 17:11:55 +00:00
Eelco Dolstra 2d5114452d * Regression test for the `exportReferencesGraph'
derivation attribute.
2009-03-17 16:33:48 +00:00
Eelco Dolstra 0008b0006d * Simplify deleting .lock files in /nix/store: just don't delete them
if they belong a path that's currently being built.  This gets rid
  of some Cygwin-specific code.
2008-12-12 17:03:18 +00:00
Eelco Dolstra ac36c6cd44 * Some hackery to make "make check" succeed on Cygwin. 2008-12-12 15:36:18 +00:00
Eelco Dolstra 67958f21df * Be sure to clean up the daemon if the test fails. 2008-12-04 16:55:22 +00:00
Eelco Dolstra d95b68fde3 2008-12-03 16:15:38 +00:00
Eelco Dolstra 64519cfd65 * Unify the treatment of sources copied to the store, and recursive
SHA-256 outputs of fixed-output derivations.  I.e. they now produce
  the same store path:

  $ nix-store --add x
  /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x

  $ nix-store --add-fixed --recursive sha256 x
  /nix/store/j2fq9qxvvxgqymvpszhs773ncci45xsj-x

  the latter being the same as the path that a derivation

    derivation {
      name = "x";
      outputHashAlgo = "sha256";
      outputHashMode = "recursive";
      outputHash = "...";
      ...
    };

  produces.

  This does change the output path for such fixed-output derivations.
  Fortunately they are quite rare.  The most common use is fetchsvn
  calls with SHA-256 hashes.  (There are a handful of those is
  Nixpkgs, mostly unstable development packages.)
  
* Documented the computation of store paths (in store-api.cc).
2008-12-03 15:06:30 +00:00
Eelco Dolstra 4213b8d8ec * Urgh. 2008-11-20 15:44:59 +00:00
Eelco Dolstra 3d2035ea86 * Blindly doing a replacement of occurences of $bindir (when running
the tests) is a bad idea when $bindir = /usr and some programs (like
  perl) live there.  Fortunately it doesn't seem to be needed anymore.
2008-11-20 15:08:34 +00:00
Eelco Dolstra 285d26374a * Don't set the prefix to /nix by default, rather use the Autoconf
default of /usr/local.  However, localstatedir and storedir are set
  to /nix/var/nix and /nix/store respectively unless they're
  explicitly overriden.
2008-11-20 14:14:35 +00:00
Eelco Dolstra 9279174dde * Added an experimental feature suggested by Andres: ellipses ("...")
in attribute set pattern matches.  This allows defining a function
  that takes *at least* the listed attributes, while ignoring
  additional attributes.  For instance,

    {stdenv, fetchurl, fuse, ...}:
    
    stdenv.mkDerivation {
      ...
    };
    
  defines a function that requires an attribute set that contains the 
  specified attributes but ignores others.  The main advantage is that
  we can then write in all-packages.nix

    aefs = import ../bla/aefs pkgs;

  instead of

    aefs = import ../bla/aefs {
      inherit stdenv fetchurl fuse;
    };

  This saves a lot of typing (not to mention not having to update
  all-packages.nix with purely mechanical changes).  It saves as much
  typing as the "args: with args;" style, but has the advantage that
  the function arguments are properly declared (not implicit in what
  the body of the "with" uses).
2008-08-14 14:00:44 +00:00
Eelco Dolstra 1b962fc720 * @-patterns as in Haskell. For instance, in a function definition
f = args @ {x, y, z}: ...;

  `args' refers to the argument as a whole, which is further
  pattern-matched against the attribute set pattern {x, y, z}.
2008-08-14 12:53:29 +00:00
Eelco Dolstra efe4b690ae * Refactoring: combine functions that take an attribute set and
functions that take a single argument (plain lambdas) into one AST
  node (Function) that contains a Pattern node describing the
  arguments.  Current patterns are single lazy arguments (VarPat) and
  matching against an attribute set (AttrsPat).

  This refactoring allows other kinds of patterns to be added easily,
  such as Haskell-style @-patterns, or list pattern matching.
2008-08-14 10:04:22 +00:00
Eelco Dolstra c03b729319 * Increase the sleep periods a bit to make the test less likely to
fail on slow machines.  Of course it would be better if this test
  wasn't timing dependent...
2008-08-14 09:26:30 +00:00
Eelco Dolstra 5664b6d7ba * Removed the "valid values" feature. Nobody uses it anyway. 2008-08-11 13:36:40 +00:00
Eelco Dolstra a87b5256e2 * Fix the tests. 2008-08-04 16:16:49 +00:00
Eelco Dolstra 3c92ea399d * Make nix-env --dry-run print the paths to be substituted correctly
again.  (After the previous substituter mechanism refactoring I
  didn't update the code that obtains the references of substitutable
  paths.)  This required some refactoring: the substituter programs
  are now kept running and receive/respond to info requests via
  stdin/stdout.
2008-08-02 12:54:35 +00:00
Eelco Dolstra e139d7fc68 * Fix the tests. 2008-07-18 20:03:12 +00:00
Eelco Dolstra 7cd88b1dec * Generalised the dependencyClosure primop to builtins.genericClosure,
which is hopefully more useful.
* New primops: length, mul, div.
2008-07-11 13:29:04 +00:00
Eelco Dolstra d567baabbd * Export the nix-env derivation name parsing and version comparison
logic through the `parseDrvName' and `compareVersions' primops.
  This will allow expressions to easily check whether some dependency
  is a specific needed version or falls in some version range.  See
  tests/lang/eval-okay-versions.nix for examples.
2008-07-01 10:10:32 +00:00
Eelco Dolstra ee8f15930d * Test instrumentation. 2008-06-15 15:10:03 +00:00
Eelco Dolstra 997b95a4af * Fixed compatibility with old versions of "wc" that print whitespace
before the count.
2008-06-10 10:08:15 +00:00
Eelco Dolstra b0e92f6d47 * Merged the no-bdb branch (-r10900:HEAD
https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-06-09 13:52:45 +00:00
Eelco Dolstra 4066f450c2 * Doh. 2008-02-05 13:35:49 +00:00
Eelco Dolstra e7bdde981f * Regression test. 2008-02-05 13:25:18 +00:00
Eelco Dolstra 7d0f6aed59 * New primop `unsafeDiscardStringContext' to get rid of string
contexts.  Needed to prevent unnecessary dependencies when building
  the NixOS manual.

Eelco Dolstra f60aa2aa21 2007-12-31 00:34:44 +00:00
Eelco Dolstra b5ddcf58ad * Fix the hashDerivationModulo test. I should really investigate
*why* the test failed...
2007-12-30 23:59:10 +00:00
Eelco Dolstra 1e90b4189d * Another insane Mac OS X 10.5 compatibility hack. 2007-12-14 14:15:30 +00:00
Eelco Dolstra 485d71c54a * Mac OS X 10.5 compatibility: echo -n foo' suddenly prints -n foo'
instead of `foo' without a newline (with /bin/sh, not /bin/bash,
  even though /bin/sh is also bash...).  So use printf instead.
2007-12-14 14:08:09 +00:00
Eelco Dolstra b42ef9c054 * Syntax to escape '', ${. 2007-12-06 10:20:58 +00:00
Eelco Dolstra 6d6c68c0d2 * Added a new kind of multi-line string literal delimited by two
single quotes.  Example (from NixOS):

    job = ''
      start on network-interfaces

      start script

        rm -f /var/run/opengl-driver
        ${if videoDriver == "nvidia"        
          then "ln -sf ${nvidiaDrivers} /var/run/opengl-driver"
          else if cfg.driSupport
          then "ln -sf ${mesa} /var/run/opengl-driver"
          else ""
        }

        rm -f /var/log/slim.log

      end script
    '';

  This style has two big advantages:

  - \, ' and " aren't special, only '' and ${.  So you get a lot less
    escaping in shell scripts / configuration files in Nixpkgs/NixOS.
    The delimiter '' is rare in scripts (and can usually be written as
    "").  ${ is also fairly rare.

    Other delimiters such as <<...>>, {{...}} and <|...|> were also
    considered but this one appears to have the fewest drawbacks
    (thanks Martin).

  - Indentation is intelligently stripped so that multi-line strings
    can follow the nesting structure of the containing Nix
    expression.  E.g. in the example above 6 spaces are stripped from
    the start of each line.  This prevents unnecessary indentation in
    generated files (which sometimes even breaks things).

  See tests/lang/eval-okay-ind-string.nix for some examples.

Eelco Dolstra 633518628f * nix-env -e: support uninstalling by path, so that one can say
$ nix-env -e $(which firefox)

  or

    $ nix-env -e /nix/store/nywzlygrkfcgz7dfmhm5xixlx1l0m60v-pan-0.132

* nix-env -i: if an argument contains a slash anywhere, treat it as a
  path and follow it through symlinks into the Nix store.  This allows
  things like

    $ nix-build -A firefox
    $ nix-env -i ./result

* nix-env -q/-i/-e: don't complain when the `*' selector doesn't match
  anything.  In particular, `nix-env -q \*' doesn't fail anymore on an
  empty profile.
