2010-10-22	* Store Value nodes outside of attribute sets. I.e., Attr now stores	Eelco Dolstra	1	-41/+56
	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	-5/+18

2010-10-20	* Keep some more stats.	Eelco Dolstra	1	-0/+9

2010-10-20	* Use the Boehm garbage collector to reclaim unused memory in the Nix	Eelco Dolstra	1	-9/+14
	expression evaluator.
2010-08-27	* Oops - "null" was displayed as "true".	Eelco Dolstra	1	-1/+1

2010-08-02	* Optimisation in the // operator: if one of the sets is empty, return	Eelco Dolstra	1	-6/+8
	the other set.
2010-06-10	* builtins.toXML: propagate the string context. This is a regression	Eelco Dolstra	1	-5/+9
	from the old ATerm-based evaluator.
2010-06-02	(no commit message)	Eelco Dolstra	1	-0/+1

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	-2/+19
	fast-eval branch.
2010-05-12	* Print attributes in sorted order.	Eelco Dolstra	1	-2/+7

2010-05-07	* Store position info for inherited attributes.	Eelco Dolstra	1	-10/+12

2010-05-07	* Keep track of the source positions of attributes.	Eelco Dolstra	1	-22/+37

2010-05-06	* Store attribute positions in the AST and report duplicate attribute	Eelco Dolstra	1	-13/+3
	errors with position info. * For all positions, use the position of the first character of the first token, rather than the last character of the first token plus one.
2010-04-22	* Simplify the implementation of `with'. This gives a 7% speedup in	Eelco Dolstra	1	-25/+9
	evaluating the NixOS system configuration.
2010-04-22	* String equality tests should take the context into account. All the	Eelco Dolstra	1	-3/+11
	evaluation test cases now succeed.
2010-04-21	* Fixed builtins.genericClosure.	Eelco Dolstra	1	-3/+7

2010-04-21	* Store user environment manifests as a Nix expression in	Eelco Dolstra	1	-2/+9
	$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	-10/+13

2010-04-16	* Improve sharing a bit.	Eelco Dolstra	1	-4/+7

2010-04-16	* Remove some redundant tests.	Eelco Dolstra	1	-3/+3

2010-04-16	* In an nested `with' where the inner with is a variable (`with ...;	Eelco Dolstra	1	-1/+7
	with someVar; ...'), the contents of the variable would be clobbered. (The attributes in the outer `with' were added to the variable.)
2010-04-15	* Store lists as lists of pointers to values rather than as lists of	Eelco Dolstra	1	-16/+17
	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	-4/+13

2010-04-14	* Implemented inherit.	Eelco Dolstra	1	-18/+12

2010-04-14	* Fix builtins.	Eelco Dolstra	1	-11/+9

2010-04-14	* Refactoring: move variable uses to a separate class.	Eelco Dolstra	1	-29/+13

2010-04-14	* Implemented withs.	Eelco Dolstra	1	-14/+23

2010-04-14	* After parsing, compute level/displacement pairs for each variable	Eelco Dolstra	1	-36/+55
	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	-23/+2
	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	* Use std::tr1::unordered_set instead of std::set for the symbol	Eelco Dolstra	1	-0/+1
	table. This gives a 10% speed increase on `nix-instantiate /etc/nixos/nixos -A system --readonly-mode'.
2010-04-13	* Evaluate lets directly (i.e. without desugaring to `rec { attrs...;	Eelco Dolstra	1	-0/+25
	<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	-19/+26
	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	* Finished the ATerm-less parser.	Eelco Dolstra	1	-3/+30

2010-04-12	* Indented strings.	Eelco Dolstra	1	-0/+6

2010-04-12	* More missing constructs.	Eelco Dolstra	1	-69/+59

2010-04-12	* Don't use ATerms for the abstract syntax trees anymore. Not	Eelco Dolstra	1	-223/+244
	finished yet.
2010-04-12	* Hack to support builderDefs expressions.	Eelco Dolstra	1	-1/+7

2010-04-12	* Doh.	Eelco Dolstra	1	-1/+1

2010-04-09	* Keep more statistics about stack space usage.	Eelco Dolstra	1	-39/+66
	* Reduce stack space usage.
2010-04-08	* Remove a lot of dead code.	Eelco Dolstra	1	-492/+8

2010-04-08	* Fix blackholing. If evaluation fails due to an assertion failure,	Eelco Dolstra	1	-2/+8
	then the blackhole has to be removed to ensure that repeated evaluation of the same value gives an assertion failure again rather than an "infinite recursion" error.
2010-04-07	* Update autoCallFunction() and findAlongAttrPath().	Eelco Dolstra	1	-27/+37

2010-04-07	* Implemented the primops necessary for generating the NixOS manual.	Eelco Dolstra	1	-24/+28

2010-04-06	* In eval(), don't use the target value `v' as a temporary.	Eelco Dolstra	1	-13/+17
	Overwriting `v' breaks when the expression evaluation to an assertion failure or throw.
2010-04-01	* Quick hack to make coerceToString work more or less correctly on	Eelco Dolstra	1	-1/+4
	nested lists. `nix-instantiate' can now evaluate the NixOS system derivation attribute correctly (in 2.1s on my laptop vs. 6.2s for the trunk).
2010-04-01	* Improve sharing.	Eelco Dolstra	1	-3/+2

2010-04-01	* Functions are incomparable.	Eelco Dolstra	1	-6/+13

2010-04-01	* Make `derivation' lazy again for performance. It also turns out	Eelco Dolstra	1	-9/+1
	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	* Fixed the trace primop and path comparison.	Eelco Dolstra	1	-0/+3
	* Removed exprToString and stringToExpr because there is no ATerm representation to work on anymore (and exposing the internals of the evaluator like this is not a good idea anyway).
