2004-02-16	* Inherited attributes in recursive attribute sets are in scope of the	Eelco Dolstra	1	-4/+11
	non-inherited attributes.
2004-02-04	* Use a map to lookup primops.	Eelco Dolstra	1	-2/+21
	* Various performance improvements in the evaluator. * Do not link against unused (and missing!) libraries (-lsglr, etc.).
2004-02-03	* Verify that all variables in a Nix expression are defined.	Eelco Dolstra	1	-12/+63

2004-02-02	* Added syntactic sugar to the construction of attribute sets to	Eelco Dolstra	1	-4/+6
	`inherit' variables from the surrounding lexical scope. E.g., {stdenv, libfoo}: derivation { builder = ./bla; inherit stdenv libfoo; xyzzy = 1; } is equivalent to {stdenv, libfoo}: derivation { builder = ./bla; stdenv = stdenv; libfoo = libfoo; xyzzy = 1; } Note that for mutually recursive attribute set definitions (`rec {...}'), this also works, that is, `rec {inherit x;}' is equivalent to `let {fresh = x; body = rec {x = fresh;};}', not `rec {x = x}'.
2004-01-21	* Fixed a subtle uninitialised variable bug in ATermMaps copied from	Eelco Dolstra	1	-1/+3
	ATermMaps. Found thanks to Valgrind!
2004-01-15	* Catch SIGINT to terminate cleanly when the user tries to interrupt	Eelco Dolstra	1	-0/+4
	Nix. This is to prevent Berkeley DB from becoming wedged. Unfortunately it is not possible to throw C++ exceptions from a signal handler. In fact, you can't do much of anything except change variables of type `volatile sig_atomic_t'. So we set an interrupt flag in the signal handler and check it at various strategic locations in the code (by calling checkInterrupt()). Since this is unlikely to cover all cases (e.g., (semi-)infinite loops), sometimes SIGTERM may now be required to kill Nix.
2003-11-19	* Refactoring: put the Nix expression evaluator in its own library so	Eelco Dolstra	1	-0/+215
	that it can be used by multiple programs.
