2016-01-05	Use __toString when coercing sets to strings.	Shea Levy	1	-1/+9
	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.

2015-07-31	Output line number on infinite recursion	Iwan Aucamp	1	-8/+8

2015-07-23	Cleanup	Eelco Dolstra	1	-5/+0

2015-07-23	Optimize empty sets	Eelco Dolstra	1	-0/+4
	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	1	-30/+0
	Conflicts: src/libexpr/eval.cc
2015-07-23	Optimize small lists	Eelco Dolstra	1	-33/+46
	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	1	-45/+45

2015-07-17	Make printValue() interruptible	Eelco Dolstra	1	-0/+2
	Fixes #572.
2015-07-14	Move attribute set data structures into their own header file.	Nicolas B. Pierron	1	-30/+0
	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	1	-1/+13
	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	1	-0/+7
	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	1	-0/+5

2015-03-25	addToStore(): Take explicit name argument	Eelco Dolstra	1	-1/+1

2015-03-19	Disable scanning for interior pointers	Eelco Dolstra	1	-0/+2
	This may remove the "Repeated allocation of very large block" warnings.
2015-03-19	Fix Boehm API violation	Eelco Dolstra	1	-38/+42
	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	1	-11/+34

2015-03-18	Print some Boehm GC stats	Eelco Dolstra	1	-0/+7

2015-03-18	valueSize(): Take into account list/bindings/env size	Eelco Dolstra	1	-6/+15

2015-03-06	forceValueDeep: Add to error prefix	Eelco Dolstra	1	-2/+7

2015-03-06	Improve error message	Eelco Dolstra	1	-11/+20

2015-02-23	Add restricted evaluation mode	Eelco Dolstra	1	-3/+20
	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	1	-1/+2

2014-12-12	Remove canary stuff	Eelco Dolstra	1	-21/+0

2014-12-02	Make all ExternalValueBase functions const	Shea Levy	1	-3/+3

2014-12-02	Allow external code using libnixexpr to add types	Shea Levy	1	-0/+33
	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	1	-2/+2

2014-11-15	Add functors (callable attribute sets).	Shea Levy	1	-0/+12
	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	1	-11/+1

2014-10-09	mkList: Scrub better	Eelco Dolstra	1	-0/+1
	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	1	-6/+3
	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	1	-8/+10

2014-10-01	printValue(): Don't print <CYCLE> for repeated values	Eelco Dolstra	1	-7/+9

2014-09-22	Make forceValueDeep work on values with cycles	Eelco Dolstra	1	-9/+20

2014-09-22	Rename strictForceValue -> forceValueDeep	Eelco Dolstra	1	-3/+3

2014-09-22	Handle cycles when printing a value	Eelco Dolstra	1	-5/+23
	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	1	-0/+80
	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	1	-9/+0

2014-09-19	Store Attrs inside Bindings	Eelco Dolstra	1	-14/+25
	This prevents a double allocation per attribute set.
2014-09-17	Add some instrumentation for debugging GC leaks	Eelco Dolstra	1	-0/+22

2014-09-02	Fix boost::too_many_args error	Eelco Dolstra	1	-1/+1
	Fixes #333.
2014-08-20	Use proper quotes everywhere	Eelco Dolstra	1	-14/+14

2014-08-13	Fix warning about non-existant -I directories	Eelco Dolstra	1	-1/+1

2014-06-10	== operator: Ignore string context	Eelco Dolstra	1	-11/+2
	There really is no case I can think of where taking the context into account is useful. Mostly it's just very inconvenient.
2014-05-26	Remove ExprBuiltin	Eelco Dolstra	1	-11/+0
	It's slower than ExprVar since it doesn't compute a static displacement. Since we're not using the throw primop in the implementation of <...> anymore, it's also not really needed.
2014-05-26	Ensure that -I flags get included in nixPath	Eelco Dolstra	1	-4/+3
	Also fixes #261.
