2012-03-05	Fix compilation on FreeBSD	Eelco Dolstra	1	-0/+1
	http://hydra.nixos.org/build/2213576 Not sure why compilation doesn't fail on other platforms...
2010-10-24	* Store attribute sets as a vector instead of a map (i.e. a red-black	Eelco Dolstra	1	-1/+1
	tree). This saves a lot of memory. The vector should be sorted so that names can be looked up using binary search, but this is not the case yet. (Surprisingly, looking up attributes using linear search doesn't have a big impact on performance.) Memory consumption for $ nix-instantiate /etc/nixos/nixos/tests -A bittorrent.test --readonly-mode on x86_64-linux with GC enabled is now 185 MiB (compared to 946 MiB on the trunk).
2010-10-22	* Store Value nodes outside of attribute sets. I.e., Attr now stores	Eelco Dolstra	1	-2/+3
	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.
2010-05-07	* Keep track of the source positions of attributes.	Eelco Dolstra	1	-1/+1

2010-04-15	* Store lists as lists of pointers to values rather than as lists of	Eelco Dolstra	1	-1/+1
	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.
2010-04-13	* Use a symbol table to represent identifiers and attribute names	Eelco Dolstra	1	-1/+1
	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	-3/+2
	finished yet.
2010-04-07	* Update autoCallFunction() and findAlongAttrPath().	Eelco Dolstra	1	-33/+21

2010-03-29	* Started integrating the new evaluator.	Eelco Dolstra	1	-0/+2

2007-01-13	* Cleanup.	Eelco Dolstra	1	-1/+1

2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-0/+7
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-08-23	* Pass the autoArgs to findAlongAttrPath so that "nix-instantiate	Eelco Dolstra	1	-2/+3
	foo.nix -A attr --arg name value" will work if (name, value) is needed in the evaluation leading up to "attr".
2006-07-28	* `nix-instantiate ... --arg NAME VALUE': allow arguments to be passed	Eelco Dolstra	1	-1/+1
	to functions from the command line. * nix-build: started removing backticks.
2006-07-26	* Refactoring: get the selection path stuff out of getDerivations()	Eelco Dolstra	1	-0/+74
	and put it into a separate function findAlongAttrPath().
