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.
2006-07-26	* Refactoring: get the selection path stuff out of getDerivations()	Eelco Dolstra	1	-0/+5
	and put it into a separate function findAlongAttrPath().
2006-07-19	* Better error messages (especially wrt types).	Eelco Dolstra	1	-4/+0

2006-05-02	* Optimise null-ary term builders. Also declare all term builder	Eelco Dolstra	1	-1/+0
	functions as pure, which might improve performance a bit.
2006-05-01	* Allow string concatenations involving derivations, e.g.,	Eelco Dolstra	1	-0/+5
	configureFlags = "--with-freetype2-library=" + freetype + "/lib";
2006-03-23	* In `nix-env', look for derivations inside attribute sets that have	Eelco Dolstra	1	-0/+1
	the `recurseForDerivations' attribute set to `true'.
2006-03-10	* `nix-env -qa --description' shows human-readable descriptions of	Eelco Dolstra	1	-0/+1
	packages (provided that they have a `meta.description' attribute). E.g., $ ./src/nix-env/nix-env -qa --description gcc gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for sparc-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for mips-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x (cross-compiler for arm-linux) gcc-4.0.2 GNU Compiler Collection, 4.0.x
2006-03-09	* Big speedup (factor > 2.5) in all nix-env operations that do actual	Eelco Dolstra	1	-0/+5
	instantiation, e.g. "nix-env -i" and "nix-env -qas" (but not "nix-env -qa"). It turns out that many redundant calls to addToStore(path) were made, which reads and hashes the entire path. For instance, the bash bootstrap binary in Nixpkgs would be read and hashed many times. As a result nix-env would spend around 92% of its time in the function sha256_block (according to callgrind). Some simple memoization fixes this.
