2010-10-23	* Make Value smaller by not storing redundant PrimOp info.	Eelco Dolstra	1	-9/+23
	* Clear pointers in Values after overwriting them to make sure that no objects are kept alive unnecessarily.
2010-10-23	* Remove allocValues().	Eelco Dolstra	1	-1/+0

2010-10-22	* In environments, store pointers to values rather than values. This	Eelco Dolstra	1	-9/+1
	improves GC effectiveness a bit more (because a live value doesn't keep other values in the environment plus the parent environments alive), and removes the need for copy nodes.
2010-10-22	* Store Value nodes outside of attribute sets. I.e., Attr now stores	Eelco Dolstra	1	-2/+5
	a pointer to a Value, rather than the Value directly. This improves the effectiveness of garbage collection a lot: if the Value is stored inside the set directly, then any live pointer to the Value causes all other attributes in the set to be live as well.
2010-10-22	* Make building against the Boehm GC a configure option.	Eelco Dolstra	1	-0/+6

2010-10-20	* Keep some more stats.	Eelco Dolstra	1	-0/+3

2010-10-20	* Use the Boehm garbage collector to reclaim unused memory in the Nix	Eelco Dolstra	1	-1/+4
	expression evaluator.
2010-10-04	* Make sure that config.h is included before the system headers,	Eelco Dolstra	1	-2/+2
	because it defines _FILE_OFFSET_BITS. Without this, on OpenSolaris the system headers define it to be 32, and then the 32-bit stat() ends up being called with a 64-bit "struct stat", or vice versa. This also ensures that we get 64-bit file sizes everywhere. * Remove the redundant call to stat() in parseExprFromFile(). The file cannot be a symlink because that's the exit condition of the loop before.
2010-10-04	* Hack needed for GCC 4.3.2 on OpenSolaris.	Eelco Dolstra	1	-1/+1

2010-06-10	* builtins.toXML: propagate the string context. This is a regression	Eelco Dolstra	1	-0/+2
	from the old ATerm-based evaluator.
2010-05-18	* The << operator on values should be const.	Eelco Dolstra	1	-1/+1

2010-05-15	* Restore the __overrides feature that was lost somewhere in the	Eelco Dolstra	1	-1/+2
	fast-eval branch.
2010-05-07	* Keep track of the source positions of attributes.	Eelco Dolstra	1	-1/+10

2010-04-22	* Simplify the implementation of `with'. This gives a 7% speedup in	Eelco Dolstra	1	-0/+1
	evaluating the NixOS system configuration.
2010-04-22	* String equality tests should take the context into account. All the	Eelco Dolstra	1	-1/+1
	evaluation test cases now succeed.
2010-04-21	* Fixed builtins.genericClosure.	Eelco Dolstra	1	-1/+1

2010-04-21	* Store user environment manifests as a Nix expression in	Eelco Dolstra	1	-1/+10
	$out/manifest.nix rather than as an ATerm. (Hm, I thought I committed this two days ago...)
2010-04-16	* Updated some more primops.	Eelco Dolstra	1	-0/+1

2010-04-15	* Store lists as lists of pointers to values rather than as lists of	Eelco Dolstra	1	-2/+2
	values. This improves sharing and gives another speed up. Evaluation of the NixOS system attribute is now almost 7 times faster than the old evaluator.
2010-04-14	* Better stats.	Eelco Dolstra	1	-1/+3

2010-04-14	* Fix builtins.	Eelco Dolstra	1	-0/+9

2010-04-14	* Refactoring: move variable uses to a separate class.	Eelco Dolstra	1	-1/+1

2010-04-14	* After parsing, compute level/displacement pairs for each variable	Eelco Dolstra	1	-8/+8
	use site, allowing environments to be stores as vectors of values rather than maps. This should speed up evaluation and reduce the number of allocations.
2010-04-14	* Change the semantics of "with" so that inner "withs" take	Eelco Dolstra	1	-2/+0
	precedence, i.e. `with {x=1;}; with {x=2;}; x' evaluates to 2'. This has a simpler implementation and seems more natural. There doesn't seem to be any code in Nixpkgs or NixOS that relies on the old behaviour.
2010-04-13	* Evaluate lets directly (i.e. without desugaring to `rec { attrs...;	Eelco Dolstra	1	-0/+1
	<let-body> = e; }.<let-body>). This prevents the unnecessary allocation of an attribute set.
2010-04-13	* Use a symbol table to represent identifiers and attribute names	Eelco Dolstra	1	-3/+13
	efficiently. The symbol table ensures that there is only one copy of each symbol, thus allowing symbols to be compared efficiently using a pointer equality test.
2010-04-12	* Don't use ATerms for the abstract syntax trees anymore. Not	Eelco Dolstra	1	-13/+33
	finished yet.
2010-04-09	* Keep more statistics about stack space usage.	Eelco Dolstra	1	-4/+12
	* Reduce stack space usage.
2010-04-07	* Update autoCallFunction() and findAlongAttrPath().	Eelco Dolstra	1	-28/+6

2010-04-07	* Implemented the primops necessary for generating the NixOS manual.	Eelco Dolstra	1	-7/+14

2010-04-01	* Improve sharing.	Eelco Dolstra	1	-0/+7

2010-04-01	* Make `derivation' lazy again for performance. It also turns out	Eelco Dolstra	1	-0/+8
	that there are some places in Nixpkgs (php_configurable / composableDerivation, it seems) that call `derivation' with incorrect arguments (namely, the `name' attribute missing) but get away with it because of laziness.
2010-03-31	* Handle string contexts. `nix-instantiate' can now correctly compute	Eelco Dolstra	1	-0/+1
	the `firefoxWrapper' attribute in Nixpkgs, and it's about 3 times faster than the trunk :-)
2010-03-31	* Cache parse trees to prevent repeated parsing of imported Nix	Eelco Dolstra	1	-0/+2
	expressions.
2010-03-31	* Implemented derivations.	Eelco Dolstra	1	-2/+7

2010-03-30	* More primops.	Eelco Dolstra	1	-1/+2

2010-03-30	* More operators / primops.	Eelco Dolstra	1	-14/+4

2010-03-30	* More primops.	Eelco Dolstra	1	-4/+6

2010-03-30	* More primops.	Eelco Dolstra	1	-0/+4

2010-03-30	* Implemented `map'.	Eelco Dolstra	1	-1/+12

2010-03-30	* Make `import' work.	Eelco Dolstra	1	-14/+24

2010-03-29	* Started integrating the new evaluator.	Eelco Dolstra	1	-10/+142

2009-05-12	* Allow unsafe (unspecified) comparisons between attrsets unless	Eelco Dolstra	1	-0/+2
	NIX_NO_UNSAFE_EQ is set, for now.
2007-01-13	* Memoize strict evaluation.	Eelco Dolstra	1	-2/+1

2006-10-16	* Big cleanup of the semantics of paths, strings, contexts, string	Eelco Dolstra	1	-7/+16
	concatenation and string coercion. This was a big mess (see e.g. NIX-67). Contexts are now folded into strings, so that they don't cause evaluation errors when they're not expected. The semantics of paths has been clarified (see nixexpr-ast.def). toString() and coerceToString() have been merged. Semantic change: paths are now copied to the store when they're in a concatenation (and in most other situations - that's the formalisation of the meaning of a path). So "foo " + ./bla evaluates to "foo /nix/store/hash...-bla", not "foo /path/to/current-dir/bla". This prevents accidental impurities, and is more consistent with the treatment of derivation outputs, e.g., `"foo " + bla' where `bla' is a derivation. (Here `bla' would be replaced by the output path of `bla'.)
2006-09-22	* Builtin function `add' to add integers.	Eelco Dolstra	1	-0/+1
	* Put common test functions in tests/lang/lib.nix.
2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-4/+12
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-08-30	* Okay, that's a bit harder than expected.	Eelco Dolstra	1	-2/+5

2006-08-24	* Refactoring: move strictEval to libexpr.	Eelco Dolstra	1	-0/+4

2006-07-28	* `nix-instantiate ... --arg NAME VALUE': allow arguments to be passed	Eelco Dolstra	1	-3/+3
	to functions from the command line. * nix-build: started removing backticks.
