2016-08-29 Add builtin function "partition"Eelco Dolstra5-10/+48
The implementation of "partition" in Nixpkgs is O(n^2) (because of the use of ++), and for some reason was causing stack overflows in multi-threaded evaluation (not sure why). This reduces "nix-env -qa --drv-path" runtime by 0.197s and memory usage by 298 MiB (in non-Boehm mode).
2016-08-29 nix path-info: Add --json flagEelco Dolstra3-99/+30
Also, factor out JSON generation from value-to-json.{cc,hh}, and support producing indented JSON.
2016-08-29 callFunction: Copy functors to the heapShea Levy1-4/+11
Normally it's impossible to take a reference to the function passed to callFunction, so some callers (e.g. ExprApp::eval) allocate that value on the stack. For functors, a reference to the functor itself may be kept, so we need to have it on the heap. Fixes #1045
2016-08-23 nix build: Use Nix search pathEelco Dolstra2-5/+8
That is, unless --file is specified, the Nix search path is synthesized into an attribute set. Thus you can say $ nix build nixpkgs.hello assuming $NIX_PATH contains an entry of the form "nixpkgs=...". This is more verbose than $ nix build hello but is less ambiguous.
2016-08-17 Add a mechanism for derivation attributes to reference the derivation's outputsEelco Dolstra1-0/+14
For example, you can now say: configureFlags = "--prefix=${placeholder "out"} --includedir=${placeholder "dev"}"; The strings returned by the ‘placeholder’ builtin are replaced at build time by the actual store paths corresponding to the specified outputs. Previously, you had to work around the inability to self-reference by doing stuff like: preConfigure = '' configureFlags+=" --prefix $out --includedir=$dev" ''; or rely on ad-hoc variable interpolation semantics in Autoconf or Make (e.g. --prefix=\$(out)), which doesn't always work.

2016-04-29 Support Git repos in the Nix pathEelco Dolstra3-37/+61
E.g. $ nix-build -I nixpkgs=git://github.com/NixOS/nixpkgs '<nixpkgs>' -A hello This is not extremely useful yet because you can't specify a branch/revision.
2016-04-29 Add fetchgit builtinEelco Dolstra1-0/+77
The function builtins.fetchgit fetches Git repositories at evaluation time, similar to builtins.fetchTarball. (Perhaps the name should be changed, being confusing with respect to Nixpkgs's fetchgit function, with works at build time.) Example: (import (builtins.fetchgit git://github.com/NixOS/nixpkgs) {}).hello or (import (builtins.fetchgit { url = git://github.com/NixOS/nixpkgs-channels; rev = "nixos-16.03"; }) {}).hello Note that the result does not contain a .git directory.
2016-04-25 Improved logging abstractionEelco Dolstra3-8/+7
This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type.

2016-04-14 Make $NIX_PATH parsing more robustEelco Dolstra1-5/+32
2016-04-14 Make the search path lazier with non-fatal errorsEelco Dolstra4-34/+69
Thus, -I / $NIX_PATH entries are now downloaded only when they are needed for evaluation. An error to download an entry is a non-fatal warning (just like non-existant paths). This does change the semantics of builtins.nixPath, which now returns the original, rather than resulting path. E.g., before we had [ { path = "/nix/store/hgm3yxf1lrrwa3z14zpqaj5p9vs0qklk-nixexprs.tar.xz"; prefix = "nixpkgs"; } ... ] but now [ { path = "https://nixos.org/channels/nixos-16.03/nixexprs.tar.xz"; prefix = "nixpkgs"; } ... ] Fixes #792.

2016-02-04 Eliminate the "store" global variableEelco Dolstra6-36/+40
Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)

Also show types when nix cannot compare values of different types. This is also more consistent since types are already shown when comparing values of the same not comparable type.
2016-01-05 Use __toString when coercing sets to strings.Shea Levy2-2/+10
For example, "${{ foo = "bar"; __toString = x: x.foo; }}" evaluates to "bar". With this, we can delay calling functions like mkDerivation, buildPythonPackage, etc. until we actually need a derivation, enabling overrides and other modifications to happen by simple attribute set update.
