2016-04-25	Improved logging abstraction	Eelco Dolstra
	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 robust	Eelco Dolstra

2016-04-14	Make the search path lazier with non-fatal errors	Eelco Dolstra
	Thus, -I / $NIX_PATH entries are now downloaded only when they are needed for evaluation. An error to download an entry is a non-fatal warning (just like non-existant paths). This does change the semantics of builtins.nixPath, which now returns the original, rather than resulting path. E.g., before we had [ { path = "/nix/store/hgm3yxf1lrrwa3z14zpqaj5p9vs0qklk-nixexprs.tar.xz"; prefix = "nixpkgs"; } ... ] but now [ { path = "https://nixos.org/channels/nixos-16.03/nixexprs.tar.xz"; prefix = "nixpkgs"; } ... ] Fixes #792.
2016-02-12	Merge pull request #762 from ctheune/ctheune-floats	Eelco Dolstra
	Implement floats
2016-02-04	StoreAPI -> Store	Eelco Dolstra
	Calling a class an API is a bit redundant...
2016-02-04	Eliminate the "store" global variable	Eelco Dolstra
	Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)
2016-01-05	Use __toString when coercing sets to strings.	Shea Levy
	For example, "${{ 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.

2015-07-23	Cleanup	Eelco Dolstra

2015-07-23	Optimize empty sets	Eelco Dolstra
	This reduces the number of Bindings allocations by about 10%.
2015-07-23	Merge branch 'attr-set-hh' of https://github.com/nbp/nix	Eelco Dolstra
	Conflicts: src/libexpr/eval.cc
2015-07-23	Optimize small lists	Eelco Dolstra
	The value pointers of lists with 1 or 2 elements are now stored in the list value itself. In particular, this makes the "concatMap (x: if cond then [(f x)] else [])" idiom cheaper.
2015-07-17	OCD: foreach -> C++11 ranged for	Eelco Dolstra

2015-07-17	Make printValue() interruptible	Eelco Dolstra
	Fixes #572.
2015-07-14	Move attribute set data structures into their own header file.	Nicolas B. Pierron
	This modification moves Attr and Bindings structures into their own header file which is dedicated to the attribute set representation. The goal of to isolate pieces of code which are related to the attribute set representation. Thus future modifications of the attribute set representation will only have to modify these files, and not every other file across the evaluator.
2015-06-17	Support URLs in $NIX_PATH	Eelco Dolstra
	This didn't work (despite claims in the manual), because the colon in "http://" was parsed as a element separator. So handle "://" specially.
2015-05-22	Fix import-from-derivation in restricted eval mode	Eelco Dolstra
	This relaxes restricted mode to allow access to anything in the store. In the future, it would be better to allow access to only paths that have been constructed in the current evaluation (so a hard-coded /nix/store/blabla in a Nix expression would still be rejected). However, note that reading /nix/store itself is still rejected, so you can't use this so get access to things you don't know about.
2015-04-16	Fix using restricted mode with chroots	Eelco Dolstra

2015-03-25	addToStore(): Take explicit name argument	Eelco Dolstra

2015-03-19	Disable scanning for interior pointers	Eelco Dolstra
	This may remove the "Repeated allocation of very large block" warnings.
2015-03-19	Fix Boehm API violation	Eelco Dolstra
	We were calling GC_INIT() after doing an allocation (in the baseEnv construction), which is not allowed.
2015-03-19	Check return values from malloc/strdup	Eelco Dolstra

2015-03-18	Print some Boehm GC stats	Eelco Dolstra

2015-03-18	valueSize(): Take into account list/bindings/env size	Eelco Dolstra

2015-03-06	forceValueDeep: Add to error prefix	Eelco Dolstra

2015-03-06	Improve error message	Eelco Dolstra

2015-02-23	Add restricted evaluation mode	Eelco Dolstra
	If ‘--option restrict-eval true’ is given, the evaluator will throw an exception if an attempt is made to access any file outside of the Nix search path. This is primarily intended for Hydra, where we don't want people doing ‘builtins.readFile ~/.ssh/id_dsa’ or stuff like that.
2015-02-19	ExprConcatStrings: canonicalize concatenated paths	Shea Levy

2014-12-12	Remove canary stuff	Eelco Dolstra

2014-12-02	Make all ExternalValueBase functions const	Shea Levy

2014-12-02	Allow external code using libnixexpr to add types	Shea Levy
	Code that links to libnixexpr (e.g. plugins loaded with importNative, or nix-exec) may want to provide custom value types and operations on values of those types. For example, nix-exec is currently using sets where a custom IO value type would be more appropriate. This commit provides a generic hook for such types in the form of tExternal and the ExternalBase virtual class, which contains all functions necessary for libnixexpr's type-polymorphic functions (e.g. `showType`) to be implemented.
2014-11-25	forceString(): Accept pos argument	Eelco Dolstra

2014-11-15	Add functors (callable attribute sets).	Shea Levy
	With this, attribute sets with a `__functor` attribute can be applied just like normal functions. This can be used to attach arbitrary metadata to a function without callers needing to treat it specially.
2014-10-31	Fix more warnings	Eelco Dolstra

2014-10-09	mkList: Scrub better	Eelco Dolstra
	Clearing v.app.right was not enough, because the length field of a list only takes 32 bits, so the most significant 32 bits of v.app.left (a.k.a. v.thunk.env) would remain. This could cause Boehm GC to interpret it as a valid pointer. This change reduces maximum RSS for evaluating the ‘tested’ job in nixos/release-small.nix from 1.33 GiB to 0.80 GiB, and runtime by about 8%.
2014-10-05	Get rid of some unnecessary ExprConcatStrings nodes in dynamic attrs	Eelco Dolstra
	This gives a ~18% speedup in NixOS evaluation (after converting most calls to hasAttr/getAttr to dynamic attrs).
2014-10-05	Show total allocations	Eelco Dolstra

2014-10-01	printValue(): Don't print <CYCLE> for repeated values	Eelco Dolstra

2014-09-22	Make forceValueDeep work on values with cycles	Eelco Dolstra

2014-09-22	Rename strictForceValue -> forceValueDeep	Eelco Dolstra

2014-09-22	Handle cycles when printing a value	Eelco Dolstra
	So this no longer crashes with a stack overflow: nix-instantiate -E --eval 'let as = { x = as; }; in as' Instead it prints: { x = { x = <CYCLE>; }; }
2014-09-22	Add a function ‘valueSize’	Eelco Dolstra
	It returns the size of value, including all other values and environments reachable from it. It is intended for debugging memory consumption issues.
2014-09-19	Inline Bindings::find()	Eelco Dolstra
