2013-05-16	Show function names in error messages	Eelco Dolstra	1	-4/+9
	Functions in Nix are anonymous, but if they're assigned to a variable/attribute, we can use the variable/attribute name in error messages, e.g. while evaluating `concatMapStrings' at `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs/pkgs/lib/strings.nix:18:25': ...
2012-07-18	Use "#pragma once" to prevent repeated header file inclusion	Eelco Dolstra	1	-4/+1

2010-10-24	* Store attribute sets as a vector instead of a map (i.e. a red-black	Eelco Dolstra	1	-0/+2
	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).
2010-10-04	* If std::tr1::unordered_set is unavailable, use std::set.	Eelco Dolstra	1	-0/+9

2010-04-13	* Use std::tr1::unordered_set instead of std::set for the symbol	Eelco Dolstra	1	-1/+7
	table. This gives a 10% speed increase on `nix-instantiate /etc/nixos/nixos -A system --readonly-mode'.
2010-04-13	* Use a symbol table to represent identifiers and attribute names	Eelco Dolstra	1	-0/+75
	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.
