2008-12-03 * Unify the treatment of sources copied to the store, and recursiveEelco Dolstra3-7/+51
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).
2008-11-20 * Urgh.Eelco Dolstra1-0/+2
2008-11-20 * Blindly doing a replacement of occurences of $bindir (when runningEelco Dolstra1-1/+0
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 * Don't set the prefix to /nix by default, rather use the AutoconfEelco Dolstra1-2/+2
default of /usr/local. However, localstatedir and storedir are set to /nix/var/nix and /nix/store respectively unless they're explicitly overriden.
2008-08-14 * Added an experimental feature suggested by Andres: ellipses ("...")Eelco Dolstra7-5/+20
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 * @-patterns as in Haskell. For instance, in a function definitionEelco Dolstra5-0/+32
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 * Refactoring: combine functions that take an attribute set andEelco Dolstra5-10/+16
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 * Increase the sleep periods a bit to make the test less likely toEelco Dolstra3-12/+17
fail on slow machines. Of course it would be better if this test wasn't timing dependent...
2008-08-11 * Removed the "valid values" feature. Nobody uses it anyway.Eelco Dolstra8-34/+4
2008-08-04 * Fix the tests.Eelco Dolstra2-0/+2
2008-08-02 * Make nix-env --dry-run print the paths to be substituted correctlyEelco Dolstra2-16/+37
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.
2008-07-18 * Fix the tests.Eelco Dolstra1-0/+6
2008-07-11 * Generalised the dependencyClosure primop to builtins.genericClosure,Eelco Dolstra3-0/+380
which is hopefully more useful. * New primops: length, mul, div.
2008-07-01 * Export the nix-env derivation name parsing and version comparisonEelco Dolstra3-0/+43
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.
2008-06-15 * Test instrumentation.Eelco Dolstra1-0/+1
2008-06-10 * Fixed compatibility with old versions of "wc" that print whitespaceEelco Dolstra1-2/+2
before the count.
2008-06-09 * Merged the no-bdb branch (-r10900:HEADEelco Dolstra5-8/+78
https://svn.nixos.org/repos/nix/nix/branches/no-bdb).
2008-02-05 * Doh.Eelco Dolstra1-1/+1
2008-02-05 * Regression test.Eelco Dolstra2-2/+9
2008-01-04 * New primop `unsafeDiscardStringContext' to get rid of stringEelco Dolstra2-0/+7
contexts. Needed to prevent unnecessary dependencies when building the NixOS manual.
2007-12-31 (no commit message)Eelco Dolstra2-1/+1
2007-12-30 * Fix the hashDerivationModulo test. I should really investigateEelco Dolstra1-2/+4
*why* the test failed...
2007-12-14 * Another insane Mac OS X 10.5 compatibility hack.Eelco Dolstra1-0/+14
2007-12-14 * Mac OS X 10.5 compatibility: `echo -n foo' suddenly prints `-n foo'Eelco Dolstra1-1/+1
instead of `foo' without a newline (with /bin/sh, not /bin/bash, even though /bin/sh is also bash...). So use printf instead.
2007-12-06 * Syntax to escape '', ${.Eelco Dolstra2-2/+8
2007-11-30 * Added a new kind of multi-line string literal delimited by twoEelco Dolstra2-0/+108
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.
2007-11-29 * nix-env -e: support uninstalling by path, so that one can sayEelco Dolstra1-0/+11
$ 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.
2007-11-21 * New primop `readFile' to get the contents of a file as a string.Eelco Dolstra2-0/+2
2007-09-11 * Test the impureEnvVars feature.Eelco Dolstra3-0/+6
2007-09-04 * nix-push / generate-patches: bzip the manifest.Eelco Dolstra3-2/+5
2007-08-28 * Doh! Broken test.Eelco Dolstra1-3/+3
2007-08-28 * Test case to show that parallel builds of different fixed-outputEelco Dolstra3-1/+28
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.
2007-08-18 primop functions listToAttrs (+test), __isAttrs, __trace addedMarc Weber2-0/+9
new configuration style proposal in lib/default-unstable.nix
2007-08-14 * Hopefully this fixes the test on FreeBSD.Eelco Dolstra2-3/+3
2007-08-13 * A test for the nix-worker.Eelco Dolstra4-2/+24
2007-08-13 * Fix the tests.Eelco Dolstra12-63/+67
2007-05-15 * Allow empty argument lists in function definitions (e.g., `{}:Eelco Dolstra2-0/+2
bla'). Also allow trailing commas (`{x, y,}: ...') as a unintented consequence. Hopefully the reduce/reduce conflict won't cause any problems.
2007-02-21 * Don't use $SHELL.Eelco Dolstra3-10/+2
2007-01-29 New primitives:Eelco Dolstra6-4/+41
* `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.
2007-01-15 * builtins.filterSource: pass the type of the file ("regular",Eelco Dolstra2-1/+5
"directory", "symlink") as the second argument to the filter predicate.
2007-01-14 * Don't forget the .flags files.Eelco Dolstra1-1/+1
2007-01-14 * Option --argstr for passing string arguments easily. (NIX-75)Eelco Dolstra4-1/+22
2007-01-13 * Canonicalise ASTs in `nix-instantiate --eval': remove positionEelco Dolstra4-4/+4
info, sort attribute sets.
2006-12-12 * New primop builtins.filterSource, which can be used to filter filesEelco Dolstra3-1/+23
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 * New built-in function `builtins.attrNames' that returns theEelco Dolstra2-0/+12
names of the attributes in an attribute set.
2006-12-02 * Clear NIX_REMOTE in the tests.Eelco Dolstra1-0/+2
2006-10-19 * Checks for allowedReferences and some other features.Eelco Dolstra4-2/+100
* Use nix-build in a test.
2006-10-17 * Another test.Eelco Dolstra1-0/+1
2006-10-17 * Fix the tests wrt the AST changes, i.e., Str(s) -> Str(s, []), andEelco Dolstra19-22/+22
the semantic changes.
