Shea Levy 8f28a3ba25 Add a test for multiple outputs
This currently fails. Yay test-driven development!
2011-09-14 05:59:29 +00:00
Eelco Dolstra da18b11b05 * On FreeBSD, ‘touch’ is not in the test $PATH, so don't use it. 2011-08-08 14:08:38 +00:00
Eelco Dolstra 07340b8be7 * Add the Nix corepkgs to the end of the search path. This makes it
possible for other Nix expressions to use corepkgs (mostly useful
  for the buildenv function).
2011-08-06 18:23:38 +00:00
Eelco Dolstra c7101dac0b * Allow redirections in search path entries. E.g. if you have a
directory

    /home/eelco/src/stdenv-updates

  that you want to use as the directory for import such as

    with (import <nixpkgs> { });

  then you can say

    $ nix-build -I nixpkgs=/home/eelco/src/stdenv-updates
2011-08-06 17:48:57 +00:00
Eelco Dolstra 1578b2261d * Add lang/dir* to the distribution. 2011-08-06 16:18:54 +00:00
Eelco Dolstra 1ecc97b6bd * Add a Nix expression search path feature. Paths between angle
brackets, e.g.

    import <nixpkgs/pkgs/lib>

  are resolved by looking them up relative to the elements listed in
  the search path.  This allows us to get rid of hacks like

    import "${builtins.getEnv "NIXPKGS_ALL"}/pkgs/lib"

  The search path can be specified through the ‘-I’ command-line flag
  and through the colon-separated ‘NIX_PATH’ environment variable,
  e.g.,

    $ nix-build -I /etc/nixos ...

  If a file is not found in the search path, an error message is
  lazily thrown.
2011-08-06 16:05:24 +00:00
Eelco Dolstra d2bfe1b071 * Added a test that make sure that users cannot register
specially-crafted derivations that produce output paths belonging to
  other derivations.  This could be used to inject malware into the
  store.
2011-07-20 12:15:40 +00:00
Eelco Dolstra 4bdb51e621 * Refactoring. 2011-07-20 11:50:13 +00:00
Eelco Dolstra d5d4dcd4c9 * Allow attribute names to be strings. Based on the
allow-arbitrary-strinsg-in-names patch by Marc Weber.
2011-07-13 15:53:24 +00:00
Eelco Dolstra 0a623a10c7 * Allow a default value in attribute selection by writing
x.y.z or default

  (as originally proposed in
  https://mail.cs.uu.nl/pipermail/nix-dev/2009-September/002989.html).

  For instance, an expression like

    stdenv.lib.attrByPath ["features" "ckSched"] false args

  can now be written as

    args.features.ckSched or false
2011-07-13 12:19:57 +00:00
Eelco Dolstra 5580f3817c * Test case. 2011-07-06 10:58:53 +00:00
Ludovic Courtès 5c9e9f732d Add support for the build-timeout' and --timeout' options. 2011-06-30 15:19:13 +00:00
Eelco Dolstra d159ea1b7e * Urgh, FreeBSD doesn't have a "seq" command. 2011-02-09 14:03:16 +00:00
Eelco Dolstra 9db190eb31 * builtins.substring: if "start" is beyond the end of the string,
return the empty string.
2011-01-14 12:47:10 +00:00
Eelco Dolstra 365f3028dd * Use CamelCase for the Perl modules. 2010-12-05 17:50:29 +00:00
Eelco Dolstra f42a505ab7 * Add a script `nix-generate-patches'.
* Fix the binary patching test.
2010-12-05 17:36:02 +00:00
Eelco Dolstra d92ccbf1ac * Test whether sequences of patches work. 2010-11-17 18:01:37 +00:00
Eelco Dolstra 3d38a49840 * In the download size indication, take binary patches into account.
Hopefully this doesn't slow things down too much.
2010-11-17 17:32:25 +00:00
Eelco Dolstra f69626ed3e 2010-11-17 15:45:09 +00:00
Eelco Dolstra a07c68f05e * Finally, a test for the binary patch functionality. 2010-11-17 15:30:07 +00:00
Eelco Dolstra bf658f016f * Test that download sizes are shown correctly. 2010-11-17 14:39:02 +00:00
Eelco Dolstra 1e24cbaba3 * Fix the test. 2010-11-17 14:35:14 +00:00
Eelco Dolstra fb9368b5a0 * Sync with the trunk. 2010-11-16 12:49:47 +00:00
Eelco Dolstra e0b7fb8f27 * Keep attribute sets in sorted order to speed up attribute lookups.
* Simplify the representation of attributes in the AST.
* Change the behaviour of listToAttrs() in case of duplicate names.
2010-10-24 19:52:33 +00:00
Eelco Dolstra 02934b1200 * Regression test for listToAttr's behaviour if an attribute name
occurs multiple times.
2010-10-23 22:55:30 +00:00
Eelco Dolstra cf7e645a48 * Regression test for __overrides. 2010-10-22 15:15:12 +00:00
Eelco Dolstra 7119d38287 * In the referrers test, lower the nesting depth from 2500 to 1000 to
prevent hitting a stack overflow bug in the garbage collector.
2010-10-04 22:26:38 +00:00
Eelco Dolstra e437b08250 * Made the build hook mechanism more efficient. Rather than starting
the hook every time we want to ask whether we can run a remote build
  (which can be very often), we now reuse a hook process for answering
  those queries until it accepts a build.  So if there are N
  derivations to be built, at most N hooks will be started.
2010-08-25 20:44:28 +00:00
Eelco Dolstra 587dc8aa00 * Sync with the trunk. 2010-08-04 17:48:29 +00:00
Peter Simons 60b632b173 tests/build-hook.hook.sh: prefer more portable ... syntax over $(...) for running sub-shells
The /bin/sh interpreter on Solaris doesn't understand $(...) syntax for running
sub-shells. Consequently, this test fails on Solaris. To remedy the situation,
the script either needs to be run by /bin/bash -- which is non-standard --, or
it needs to use the ancient but portable `...` syntax.
2010-06-25 14:05:37 +00:00
Eelco Dolstra aa45027818 * Sync with the trunk. 2010-05-12 22:13:09 +00:00
Eelco Dolstra bd25ac2260 * Print attributes in sorted order. 2010-05-12 12:15:49 +00:00
Eelco Dolstra 81a4b4e49b * Implemented tryEval, the last missing primop in the fast-eval
branch.  Also added a test for tryEval.
2010-05-12 11:23:44 +00:00
Eelco Dolstra 83dfa89870 * Sync with the trunk. 2010-05-07 14:46:47 +00:00
Eelco Dolstra ebade9ff8b * Check for duplicate attribute names / function arguments. `make
check' now succeeds :-)
* An attribute set such as `{ foo = { enable = true; };
  foo.port = 23; }' now parses.  It was previously rejected, but I'm
  too lazy to implement the check.  (The only reason to reject it is
  that the reverse, `{ foo.port = 23; foo = { enable = true; }; }', is
  rejected, which is kind of ugly.)
2010-04-22 11:02:24 +00:00
Eelco Dolstra 7148df7971 * Update the expected test output (no longer an ATerm). 2010-04-21 16:22:03 +00:00
Eelco Dolstra cae4efdca3 * Because --parse-only no longer produces an ATerm, don't check the
output.  Whether it parses at all should be enough.
2010-04-21 16:02:12 +00:00
Eelco Dolstra d66ea83a76 * Sync with the trunk. 2010-04-20 09:20:29 +00:00
Eelco Dolstra f3b8833a48 * Drop the dependency on the ATerm library. 2010-04-19 14:51:58 +00:00
Eelco Dolstra a5ece7d016 * Removed the `~' operator. 2010-04-01 16:59:07 +00:00
Eelco Dolstra 5187678913 2010-03-31 15:14:23 +00:00
Eelco Dolstra f061086a93 * Fix the broken test for listToAttrs. 2010-03-31 13:35:29 +00:00
Ludovic Courtès 09381cccff Make source location info in the XML output optional.
* src/libexpr/expr-to-xml.cc (nix::showAttrs): Add `location'
  parameter.  Provide location XML attributes when it's true.  Update
  callers.
  (nix::printTermAsXML): Likewise.

* src/libexpr/expr-to-xml.hh (nix::printTermAsXML): Update prototype;
  have `location' default to `false'.

* src/nix-instantiate/nix-instantiate.cc (printResult, processExpr): Add
  `location' parameter; update callers.
  (run): Add support for `--no-location'.

* src/nix-instantiate/help.txt: Update accordingly.

* tests/lang.sh: Invoke `nix-instantiate' with `--no-location' for the
  XML tests.

* tests/lang/eval-okay-toxml.exp, tests/lang/eval-okay-to-xml.nix: New
  files.
2010-03-31 12:38:31 +00:00
Eelco Dolstra 8a10360c91 * Simplify @-patterns: only {attrs}@name' or name@{attrs}' are now
allowed.  So `name1@name2', `{attrs1}@{attrs2}' and so on are now no
  longer legal.  This is no big loss because they were not useful
  anyway.

  This also changes the output of builtins.toXML for @-patterns
  slightly.
2010-03-25 12:19:41 +00:00
Eelco Dolstra 71be50cc25 * Doh. 2010-03-23 14:51:32 +00:00
Eelco Dolstra 3bfd3a4e95 * Test "with as; with bs;" since nobody knows what its semantics is. 2010-03-23 14:26:27 +00:00
Eelco Dolstra 21b134b4e5 2010-02-24 13:13:39 +00:00
Eelco Dolstra a3c63d0d6c * Disable fsync() in SQLite if the fsync-metadata option is set to
false.
* Change the default for `fsync-metadata' to true.
* Disable `fsync-metadata' in `make check'.
2010-02-24 13:12:57 +00:00
Eelco Dolstra bb82310dba * Set the path to sqlite3 properly. 2010-02-24 11:06:17 +00:00
Eelco Dolstra 69d9df7fe6 * Don't fork so much. 2010-02-24 11:04:03 +00:00
Eelco Dolstra 1930570ad9 * Foreign key support in SQLite is not a persistent setting, so enable
it at startup.
* Implement negative caching.  Now `make check' passes.
2010-02-19 17:15:22 +00:00
Eelco Dolstra 268f9aaf28 * Implemented queryValidPaths() and verifyStore(). 2010-02-18 16:51:27 +00:00
Eelco Dolstra 817f4f7908 * Grmbl. Timing-sensitive tests are evil. 2010-02-04 14:43:43 +00:00
Eelco Dolstra 3392d32e8b * In nix-pull/nix-channel, create the manifests directory if it
doesn't exist.  The Debian packages don't include the manifests
  directory, so nix-channel would silently skip doing a nix-pull,
  resulting in everything being built from source.  Thanks to Juan
  Pedro Bolívar Puente.
2009-11-13 10:08:31 +00:00
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.
2009-09-15 13:01:46 +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 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.
2008-01-04 14:22:49 +00:00
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.
2007-11-30 16:48:45 +00:00
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.
2007-11-29 16:18:24 +00:00
Eelco Dolstra 06f95dd07c * New primop `readFile' to get the contents of a file as a string. 2007-11-21 13:49:59 +00:00
Eelco Dolstra 3339f85447 * Test the impureEnvVars feature. 2007-09-11 13:32:04 +00:00
Eelco Dolstra 9441550acb * nix-push / generate-patches: bzip the manifest. 2007-09-04 15:38:09 +00:00
Eelco Dolstra bc0429b1cd * Doh! Broken test. 2007-08-28 11:31:44 +00:00
Eelco Dolstra 455a7b9577 * Test case to show that parallel builds of different fixed-output
derivations that produce the same output path don't work properly
  wrt locking.  This happens a lot in the build farm when fetchurl
  derivations downloading the same file on different platforms are
  executed in parallel and then copied back to the main machine.
2007-08-28 09:21:47 +00:00
Marc Weber 2629998e91 primop functions listToAttrs (+test), __isAttrs, __trace added
new configuration style proposal in lib/default-unstable.nix
2007-08-18 22:12:00 +00:00
Eelco Dolstra 5c793ad03e * Hopefully this fixes the test on FreeBSD. 2007-08-14 13:43:51 +00:00
Eelco Dolstra a7e1a51fdf * A test for the nix-worker. 2007-08-13 14:56:40 +00:00
Eelco Dolstra 550ba9ebb4 * Fix the tests. 2007-08-13 13:15:02 +00:00
Eelco Dolstra ca00aa1171 * Allow empty argument lists in function definitions (e.g., `{}:
bla').  Also allow trailing commas (`{x, y,}: ...') as a unintented
  consequence.  Hopefully the reduce/reduce conflict won't cause any
  problems.
2007-05-15 12:14:37 +00:00
Eelco Dolstra 6c9fdb17fb * Don't use $SHELL. 2007-02-21 14:00:46 +00:00
Eelco Dolstra 7349bd0176 New primitives:
* `sub' to subtract two numbers.
* `stringLength' to get the length of a string.
* `substring' to get a substring of a string.  These should be enough
  to allow most string operations to be expressed.
2007-01-29 14:23:09 +00:00
Eelco Dolstra e4b0666f8e * builtins.filterSource: pass the type of the file ("regular",
"directory", "symlink") as the second argument to the filter
  predicate.
2007-01-15 08:54:51 +00:00
Eelco Dolstra 8659edc098 * Don't forget the .flags files. 2007-01-14 12:33:04 +00:00
Eelco Dolstra e418976107 * Option --argstr for passing string arguments easily. (NIX-75) 2007-01-14 12:32:44 +00:00
Eelco Dolstra f23dcdd603 * Canonicalise ASTs in `nix-instantiate --eval': remove position
info, sort attribute sets.
2007-01-13 16:17:07 +00:00
Eelco Dolstra a3e6415ba8 * New primop builtins.filterSource, which can be used to filter files
from a source directory.  All files for which a predicate function
  returns true are copied to the store.  Typical example is to leave
  out the .svn directory:

    stdenv.mkDerivation {
      ...
      src = builtins.filterSource
        (path: baseNameOf (toString path) != ".svn")
        ./source-dir;
      # as opposed to
      #   src = ./source-dir;
    }

  This is important because the .svn directory influences the hash in
  a rather unpredictable and variable way.
2006-12-12 23:05:01 +00:00
Eelco Dolstra 1a7e88bbd9 * New built-in function `builtins.attrNames' that returns the
names of the attributes in an attribute set.
2006-12-12 16:14:31 +00:00
Eelco Dolstra 626f8ee42f * Clear NIX_REMOTE in the tests. 2006-12-02 14:33:39 +00:00
Eelco Dolstra 7a4497d98c * Checks for allowedReferences and some other features.
* Use nix-build in a test.
2006-10-19 17:44:51 +00:00
Eelco Dolstra dfc042a0c1 * Another test. 2006-10-17 11:16:02 +00:00
Eelco Dolstra 9e30694f98 * Fix the tests wrt the AST changes, i.e., Str(s) -> Str(s, []), and
the semantic changes.
2006-10-17 11:08:59 +00:00
Eelco Dolstra 7d4567f2cc * Removed URIs from the evaluator (NIX-66). They are now just another
kind of notation for strings.
2006-10-11 21:59:33 +00:00
Eelco Dolstra d20c3011a0 * toFile: added an additional argument to specify the store path
suffix, e.g., `builtins.toFile "builder.sh" "..."'.
* toFile: handle references to other files correctly.
2006-10-03 14:55:54 +00:00
Eelco Dolstra ac19b333b3 * Finally, a real "let" syntax: `let x = ...; ... z = ...; in ...'. 2006-10-02 15:52:44 +00:00
Eelco Dolstra 0e705391db * Primop `toPath' to convert a string to a path.
* Primop `pathExists' to check for path existence.
2006-09-24 18:23:32 +00:00
Eelco Dolstra e47e0c2dbe * Builtin function `getEnv' for getting environment variables. 2006-09-24 17:48:41 +00:00
Eelco Dolstra df8873e14a * lessThan primitive for integer comparison. 2006-09-24 15:21:48 +00:00
Eelco Dolstra 2ab4bc44c7 * Builtin function `add' to add integers.
* Put common test functions in tests/lang/lib.nix.
2006-09-22 15:29:21 +00:00
Eelco Dolstra d315210612 * Added a builtin function `isList' to test whether a value is a list.
With this primitive, a list-flattening function can be implemented
  (NIX-55, example is in tests/lang/eval-okay-flatten.nix).
2006-09-22 14:55:19 +00:00
Eelco Dolstra c02a44183f * Builtin functions head' and tail' to return the head and tail of
list.  Useful for lots of things, such as implementing a fold
  function (see NIX-30, example is in tests/lang/eval-okay-list.nix).
2006-09-22 14:46:36 +00:00
Eelco Dolstra 8a1ab709a4 * New builtin functions builtins.{hasAttr, getAttr} to check for
attribute existence and to return an attribute from an attribute
  set, respectively.  Example: `hasAttr "foo" {foo = 1;}'.  They
  differ from the `?' and `.' operators in that the attribute name is
  an arbitrary expression.  (NIX-61)
2006-09-22 14:31:55 +00:00
Eelco Dolstra 0bd5eb71a0 * `nix-install-package --url': install from a URL (NIX-12).
* `nix-install-package --help' (NIX-9).
* `nix-install-package --non-interactive': don't prompt or pause.
* Tests for nix-install-package.
* Security fixes: filter the values obtained from the nixpkg.
2006-09-21 18:54:08 +00:00
Eelco Dolstra 7974aae81c * New primop: builtins.toFile, which writes a string into the store
and returns its path.  This can be used to (for instance) write
  builders inside a Nix expression, e.g.,

  stdenv.mkDerivation {
    builder = "
      source $stdenv/setup
      ...
    ";
    ...
  }
2006-09-01 12:07:31 +00:00
Eelco Dolstra de90fdf908 * Allow "$" in strings as long as they are not followed by "{". (Too
bad flex doesn't have lexical restrictions, the current solution
  isn't quite right...)
2006-09-01 12:04:06 +00:00
Eelco Dolstra c9586b6c3f * Fix race condition in the test. 2006-09-01 12:02:39 +00:00
Eelco Dolstra f93f7b75be * Okay, that's a bit harder than expected. 2006-08-30 13:10:04 +00:00
Eelco Dolstra dce1afdc67 * TDD: == should do a deep equality test, i.e., it should strictly
evaluate its arguments.
2006-08-30 12:25:27 +00:00
Eelco Dolstra 1f6616dabf * Backwards compatibility test for ~. 2006-08-29 15:29:19 +00:00
Eelco Dolstra 215ec2ddc6 * New primop __toXML (or builtins.toXML) to convert an expression to
an XML representation stored in a string.  This should be useful to
  pass structured information to builders.
2006-08-24 14:34:29 +00:00
Eelco Dolstra 38f18aa6d4 * New primop: abort "error message". 2006-08-23 15:46:00 +00:00
Eelco Dolstra 4a053bfdfd * A new primop `builtins', which returns an attribute set containing
all the primops.  This allows Nix expressions to test for new
  primops and take appropriate action if they're not available.  For
  instance, rather than calling a primop `foo' directly, they could
  say `if builtins ? foo then builtins.foo ... else ...'.
2006-08-23 14:39:11 +00:00
Eelco Dolstra 93d9797eda * Urgh (see NIX-56). 2006-08-22 09:34:38 +00:00
Eelco Dolstra cc0505f033 * Distribute *.exp.xml. 2006-08-17 12:21:39 +00:00
Eelco Dolstra 4874fd2d9a * Test for `nix-instantiate --eval-only --xml'. 2006-08-17 11:28:29 +00:00
Eelco Dolstra fe101fa785 * Meh. 2006-08-16 10:29:43 +00:00
Eelco Dolstra bfe19b3c37 * A test for NIX-53. 2006-08-16 10:23:02 +00:00
Eelco Dolstra f4c5531d92 * New language feature: domain checks, which check whether a function
argument has a valid value, i.e., is in a certain domain.  E.g.,

    { foo : [true false]
    , bar : ["a" "b" "c"]
    }: ...

  This previously could be done using assertions, but domain checks
  will allow the buildfarm to automatically extract the configuration
  space from functions.
2006-07-24 16:35:34 +00:00
Eelco Dolstra 88acffa20a * `touch' might not be in $PATH. 2006-07-24 16:19:08 +00:00
Eelco Dolstra b545c669a0 * Tests for domain checks. 2006-07-24 15:50:29 +00:00
Eelco Dolstra 57751fdb55 * Refactoring to support domain checks. 2006-07-24 15:16:03 +00:00
Eelco Dolstra 9c3099d328 * Purify `make check'. 2006-07-21 13:21:43 +00:00
Eelco Dolstra 7adaa6d446 * Test for runtime root finding. 2006-07-21 12:46:54 +00:00
Eelco Dolstra 410760c5ab * Doh. 2006-07-20 12:58:51 +00:00
Eelco Dolstra c15f544356 * Call find-runtime-roots.pl from the garbage collector to prevent
running applications etc. from being garbage collected.
2006-07-20 12:17:25 +00:00
Eelco Dolstra 88e54153dc * Add a precise test for hashDerivatioModulo. 2006-07-19 15:49:29 +00:00
Eelco Dolstra 2b4b0658fa * This expression has an undefined variable which isn't detected, so
evaluation fails:

    error: impossible: undefined variable `gcc'
2006-07-10 17:35:00 +00:00
Eelco Dolstra d7f40357e3 * Skip this test on Cygwin, too slow (and doesn't test anything Cygwin-specific). 2006-06-16 13:27:36 +00:00
Eelco Dolstra c7d9397fc9 * Handle $PATHs with spaces. 2006-05-29 21:53:58 +00:00
Eelco Dolstra 5cabd47394 * Allow function argument default values to refer to other arguments
of the function.  Implements NIX-45.
2006-05-08 12:52:47 +00:00
Eelco Dolstra ae55e79541 * More tests. 2006-05-02 11:20:55 +00:00
Eelco Dolstra dca43ef795 * Tests for NIX-45. 2006-05-02 11:15:04 +00:00
Eelco Dolstra 0064599a27 * String interpolation. Expressions like
"--with-freetype2-library=" + freetype + "/lib"

  can now be written as

    "--with-freetype2-library=${freetype}/lib"

  An arbitrary expression can be enclosed within ${...}, not just
  identifiers.

* Escaping in string literals: \n, \r, \t interpreted as in C, any
  other character following \ is interpreted as-is.
  
* Newlines are now allowed in string literals.
2006-05-01 14:01:47 +00:00
Eelco Dolstra 6cecad2be0 * Allow string concatenations involving derivations, e.g.,
configureFlags = "--with-freetype2-library="
      + freetype + "/lib";
2006-05-01 09:56:56 +00:00
Eelco Dolstra 03162f8f47 * Unless --with-bzip2 is specified, use a copy of bzip2 in the
externals directory.  This is in particular useful because though
  most systems have bzip2/bunzip2, they don't always have libbz2,
  which we need for bsdiff/bspatch.
2006-04-25 10:45:53 +00:00
Eelco Dolstra fdea084c36 * Allow `make check' to work in directories that have symlink
components.
2006-03-10 22:27:26 +00:00
Eelco Dolstra 37d1b1cafd * `nix-env -qa --description' shows human-readable descriptions of
packages (provided that they have a `meta.description' attribute).
  E.g.,

  $ ./src/nix-env/nix-env -qa --description gcc
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for sparc-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for mips-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x (cross-compiler for arm-linux)
  gcc-4.0.2   GNU Compiler Collection, 4.0.x
2006-03-10 16:20:42 +00:00
Eelco Dolstra a33fb2d287 * Oops. 2006-03-10 16:14:30 +00:00
Eelco Dolstra 4ada6db1fc * `nix-env -q' now accepts arguments that allow specific derivations
to be queried, e.g., `nix-env -qa firefox'.  This does require the
  argument '*' to be passed if one wants information about all
  derivations, so the old `nix-env -qa' now is `nix-env -qa "*"'.
2006-03-10 10:24:46 +00:00
Eelco Dolstra 78d84f5631 * Tests for fixed-output derivations (and attribute selection, incidentally). 2006-03-01 18:26:21 +00:00
Eelco Dolstra 2167bf6b72 * Tests to prevent a repeat of the parseHash32 debacle. 2006-03-01 18:11:41 +00:00
Eelco Dolstra 1bdceb421f * Doh! 2006-03-01 16:52:55 +00:00
Eelco Dolstra fa95f4be3f * More test coverage. 2006-03-01 16:26:13 +00:00
Eelco Dolstra 80b5c71684 * Doh! 2006-03-01 16:03:32 +00:00
Eelco Dolstra e3daee919d * Test `nix-store -q --binding'. 2006-03-01 15:46:22 +00:00
Eelco Dolstra ea9c35d3cc * Test nix-store --add' and nix-store -q --hash'. 2006-03-01 15:43:37 +00:00
Eelco Dolstra b90787290d * TDD! Woohoo! 2006-03-01 14:26:03 +00:00
Eelco Dolstra 089c41a0c2 * Oops! 2006-03-01 14:17:00 +00:00
Eelco Dolstra ca0b23c831 * Test the nix-store --gc subflags. 2006-03-01 14:00:27 +00:00
Eelco Dolstra 5cb6c42088 * Test nix-build. This also tests indirect roots. 2006-03-01 13:49:12 +00:00
Eelco Dolstra 8cd646b6af * Clear the substitutes prior to running the test. 2006-03-01 13:33:12 +00:00
Eelco Dolstra e48bd8c8b5 * Add a test for nix-log2xml. 2006-03-01 13:25:08 +00:00
Eelco Dolstra 84c4631221 * Simplification. 2006-03-01 12:51:18 +00:00
Eelco Dolstra a4c63c6e8e * Make it easy to run individual tests from the command line. 2006-03-01 12:15:33 +00:00
Eelco Dolstra 9d3bee50ad * Aha! 2006-02-22 15:20:11 +00:00
Eelco Dolstra 17f39049cf * WTF? 2006-02-22 15:09:47 +00:00
Eelco Dolstra f0d6318dd1 * More tests. 2006-02-22 14:02:44 +00:00
Eelco Dolstra ddb78dfc3d * Check whether "nix-store -q --graph" generates a valid dot graph.
* Test "nix-store -q --tree" as well.
2006-02-22 13:55:41 +00:00
Eelco Dolstra 7a3e715980 * Fix for NIX-31: "nix-env -i foo" installing all derivations named
foo.  Now it will only install the one with the highest version
  number.
2006-02-17 17:47:54 +00:00

Eelco Dolstra 5144f750c4 * Typo. 2005-12-15 17:04:02 +00:00
Eelco Dolstra ab5c6bb3a3 * Change referer' to referrer' throughout. In particular, the
nix-store query options `--referer' and `--referer-closure' have
  been changed to `--referrer' and `--referrer-closure' (but the old
  ones are still accepted for compatibility).
2005-12-13 21:04:48 +00:00
Eelco Dolstra 18bbcb1214 * Add a test to demonstrate the quadratic complexity of referrer

2005-07-25 07:25:18 +00:00
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 32fa82a56a * Acquire a global GC lock to prevent new temporary root files from
being created after the garbage collector has read the temproots

  garbage collector could periodically release the GC lock to allow
  them to run.
2005-01-31 22:23:49 +00:00
Eelco Dolstra 89c9bc11ab * Add a test for a more subtle race: a process starting after the

Eelco Dolstra 1328aa3307 * Start of concurrent garbage collection. Processes write temporary
roots to a per-process temporary file in /nix/var/nix/temproots
  while holding a write lock on that file.  The garbage collector
  acquires read locks on all those files, thus blocking further
  progress in other Nix processes, and reads the sets of temporary
  roots.
2005-01-31 10:27:25 +00:00
Eelco Dolstra a7668411a1 * Add a test to check whether concurrent garbage collection (i.e.,

Eelco Dolstra 52bf9b86bb * In nix-store: added query `--referers-closure' that returns the
closure of the referers relation rather than the references
  relation, i.e., the set of all paths that directly or indirectly
  refer to the given path.  Note that contrary to the references
  closure this set is not fixed; it can change as paths are added to
  or removed from the store.
2005-01-25 11:18:03 +00:00
Eelco Dolstra 80faa2f98a * In nix-store: change --build' back to --realise'. Also brought

* Don't use local file names in tests since they will produce
  different parse trees depending on the current directory.
2004-10-27 13:12:58 +00:00
Eelco Dolstra 3277c9432a * Bug fix in parsing of /* ... */ comments; due to longest match
regexp there could be only one such comment per file.
2004-10-27 13:00:31 +00:00
Eelco Dolstra 463e2817c5 * Remove ancient Fix tests.

2004-10-27 12:41:53 +00:00
Eelco Dolstra 8f1dcdfc0a * Make sure that no build hook is set by default in the tests.
* Don't use `seq' - some primitive, obsolete operating systems
  (Darwin) don't have it.
2004-08-19 09:09:09 +00:00
Eelco Dolstra 2746a879e2 * Typo. 2004-06-28 12:07:07 +00:00
Eelco Dolstra 91dc023665 * Added a switch `--fallback'. From the manual:
Whenever Nix attempts to realise a derivation for which a closure is
  already known, but this closure cannot be realised, fall back on
  normalising the derivation.

  The most common scenario in which this is useful is when we have
  registered substitutes in order to perform binary distribution from,
  say, a network repository.  If the repository is down, the
  realisation of the derivation will fail.  When this option is
  specified, Nix will build the derivation instead.  Thus, binary
  installation falls back on a source installation.  This option is
  not the default since it is generally not desirable for a transient
  failure in obtaining the substitutes to lead to a full build from
  source (with the related consumption of resources).
2004-06-28 10:42:57 +00:00
Eelco Dolstra b113edeab7 * A flag `--keep-going / -k' to keep building goals if one fails, as
much as possible.  (This is similar to GNU Make's `-k' flag.)

* Refactoring to implement this: previously we just bombed out when
  a build failed, but now we have to clean up.  In particular this
  means that goals must be freed quickly --- they shouldn't hang
  around until the worker exits.  So the worker now maintains weak
  pointers in order not to prevent garbage collection.

* Documented the `-k' and `-j' flags.
2004-06-25 15:36:09 +00:00
Eelco Dolstra a29c8ac51c * Add a test to check that when we cannot realise a closure
expression, we should invalidate it and go back to the derivation
  for which it is a successor.
2004-06-24 14:35:01 +00:00
Eelco Dolstra ec32627621 * Multiple and/or failing substitutes now work. 2004-06-24 13:40:38 +00:00
Eelco Dolstra 8052aef486 * A test for multiple and/or failing substitutes. 2004-06-24 12:56:24 +00:00
Eelco Dolstra 88fb4f6e53 * Missing files added to `make dist'. 2004-06-21 12:20:47 +00:00
Eelco Dolstra 112ee89501 * Re-enable support for substitutes in the normaliser.
* A better substitute mechanism.

  Instead of generating a store expression for each store path for
  which we have a substitute, we can have a single store expression
  that builds a generic program that is invoked to build the desired
  store path, which is passed as an argument.

  This means that operations like `nix-pull' only produce O(1) files
  instead of O(N) files in the store when registering N substitutes.
  (It consumes O(N) database storage, of course, but that's not a
  performance problem).

* Added a test for the substitute mechanism.
  
* `nix-store --substitute' reads the substitutes from standard input,
  instead of from the command line.  This prevents us from running
  into the kernel's limit on command line length.
2004-06-20 19:17:54 +00:00
Eelco Dolstra 23bb902d1f * Re-enable build hooks. 2004-06-19 21:45:04 +00:00
Eelco Dolstra 41ec982f31 * Big refactoring. Move to a much more explicitly state machine based
approach.  This makes it much easier to add extra complexity in the
  normaliser / realiser (e.g., build hooks, substitutes).
2004-06-18 18:09:32 +00:00
Eelco Dolstra 2fa3304933 * Set the executable bit. 2004-05-13 20:28:20 +00:00
Eelco Dolstra 3426d19547 * Perform all tests. 2004-05-13 19:16:48 +00:00
Eelco Dolstra a8306cb98f * The build hooks used to implement distributed builds can now be run
in parallel.  Hooks are more efficient: locks on output paths are
  only acquired when the hook says that it is willing to accept a
  build job.  Hooks now work in two phases.  First, they should first
  tell Nix whether they are willing to accept a job.  Nix guarantuees
  that no two hooks will ever be in the first phase at the same time
  (this simplifies the implementation of hooks, since they don't have
  to perform locking (?)).  Second, if they accept a job, they are
  then responsible for building it (on the remote system), and copying
  the result back.  These can be run in parallel with other hooks and
  locally executed jobs.

  The implementation is a bit messy right now, though.  

* The directory `distributed' shows a (hacky) example of a hook that
  distributes build jobs over a set of machines listed in a
  configuration file.
2004-05-13 19:14:49 +00:00
Eelco Dolstra 5087c8f645 * Use `-j0'. 2004-05-12 14:30:57 +00:00
Eelco Dolstra efa5fa1a91 * A switch `-j NUMBER' to set the maximum number of parallel jobs (0 =
no limit).
* Add missing file to distribution.
2004-05-12 14:20:32 +00:00
Eelco Dolstra 1f48aa0be7 * Broken test. 2004-05-12 13:49:10 +00:00
Eelco Dolstra 8c0b42f857 * An quick and dirty hack to support distributed builds. 2004-05-12 09:35:51 +00:00
Eelco Dolstra c8d3882cdc * True parallel builds. Nix can now run as many build jobs in
parallel as possible (similar to GNU Make's `-j' switch).  This is
  useful on SMP systems, but it is especially useful for doing builds
  on multiple machines.  The idea is that a large derivation is
  initiated on one master machine, which then distributes
  sub-derivations to any number of slave machines.  This should not
  happen synchronously or in lock-step, so the master must be capable
  of dealing with multiple parallel build jobs.  We now have the
  infrastructure to support this.

  TODO: substitutes are currently broken.
2004-05-11 18:05:44 +00:00
Eelco Dolstra a9858c9f26 * A test to verify that Nix executes build jobs in parallel, if
possible.

  This test fails right now because this hasn't been implemented right
  now.  Yes, I'm doing Test-Driven Development! ;-)
2004-05-04 17:04:17 +00:00
Eelco Dolstra f044ccf702 * 1000th revision!
