2011-01-14	* builtins.substring: if "start" is beyond the end of the string,	Eelco Dolstra	1	-1/+1
	return the empty string.
2010-10-24	* When allocating an attribute set, reserve enough space for all	Eelco Dolstra	1	-11/+12
	elements. This prevents the vector from having to resize itself.
2010-10-24	* Keep attribute sets in sorted order to speed up attribute lookups.	Eelco Dolstra	1	-8/+24
	* Simplify the representation of attributes in the AST. * Change the behaviour of listToAttrs() in case of duplicate names.
2010-10-24	* Don't create thunks for variable lookups (if possible). This	Eelco Dolstra	1	-1/+1
	significantly reduces the number of values allocated (e.g. from 8.7m to 4.9m for the Bittorrent test).
2010-10-24	* Store attribute sets as a vector instead of a map (i.e. a red-black	Eelco Dolstra	1	-28/+37
	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).
2010-10-23	* Remove allocValues().	Eelco Dolstra	1	-16/+7

2010-10-22	* Store Value nodes outside of attribute sets. I.e., Attr now stores	Eelco Dolstra	1	-36/+34
	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.
2010-10-04	* Make sure that config.h is included before the system headers,	Eelco Dolstra	1	-1/+1
	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.
2010-08-02	* intersectAttrs: optimise for the case where the second set is larger	Eelco Dolstra	1	-7/+7
	than the first set. (That's usually the case with callPackage.)
2010-06-01	* Turn build errors during evaluation into EvalErrors.	Eelco Dolstra	1	-1/+5

2010-05-12	* Implemented tryEval, the last missing primop in the fast-eval	Eelco Dolstra	1	-12/+6
	branch. Also added a test for tryEval.
2010-05-07	* Sync with the trunk.	Eelco Dolstra	1	-1/+1

2010-05-07	* Updated addErrorContext.	Eelco Dolstra	1	-6/+7

2010-05-07	* Keep track of the source positions of attributes.	Eelco Dolstra	1	-30/+36

2010-04-21	* Fixed builtins.genericClosure.	Eelco Dolstra	1	-22/+54

2010-04-21	* Store user environment manifests as a Nix expression in	Eelco Dolstra	1	-14/+17
	$out/manifest.nix rather than as an ATerm. (Hm, I thought I committed this two days ago...)
2010-04-19	* Don't use the ATerm library for parsing/printing .drv files.	Eelco Dolstra	1	-1/+1

2010-04-16	* Updated some more primops.	Eelco Dolstra	1	-48/+23

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

2010-04-15	* Store lists as lists of pointers to values rather than as lists of	Eelco Dolstra	1	-11/+16
	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	* Fix builtins.	Eelco Dolstra	1	-15/+11

2010-04-14	* After parsing, compute level/displacement pairs for each variable	Eelco Dolstra	1	-0/+4
	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.
2010-04-13	* Use a symbol table to represent identifiers and attribute names	Eelco Dolstra	1	-13/+14
	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	-2/+2

2010-04-12	* Don't use ATerms for the abstract syntax trees anymore. Not	Eelco Dolstra	1	-20/+18
	finished yet.
2010-04-07	* expr-to-xml -> value-to-xml.	Eelco Dolstra	1	-1/+1

2010-04-07	* Implemented the primops necessary for generating the NixOS manual.	Eelco Dolstra	1	-30/+34

2010-04-01	* Make `derivation' lazy again for performance. It also turns out	Eelco Dolstra	1	-28/+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	* Fixed the trace primop and path comparison.	Eelco Dolstra	1	-41/+8
	* 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).
2010-03-31	* Handle string contexts. `nix-instantiate' can now correctly compute	Eelco Dolstra	1	-2/+2
	the `firefoxWrapper' attribute in Nixpkgs, and it's about 3 times faster than the trunk :-)
2010-03-31	* Implemented derivations.	Eelco Dolstra	1	-85/+65

2010-03-30	* More primops.	Eelco Dolstra	1	-86/+98

2010-03-30	* More operators / primops.	Eelco Dolstra	1	-27/+28

2010-03-30	* More primops.	Eelco Dolstra	1	-51/+53

2010-03-30	* More primops.	Eelco Dolstra	1	-86/+23

2010-03-30	* Implemented `map'.	Eelco Dolstra	1	-7/+15

2010-03-30	* Make `import' work.	Eelco Dolstra	1	-14/+9

2010-03-29	* Started integrating the new evaluator.	Eelco Dolstra	1	-16/+42

2010-03-25	* Simplify @-patterns: only `{attrs}@name' or `name@{attrs}' are now	Eelco Dolstra	1	-6/+1
	allowed. So `name1@name2', `{attrs1}@{attrs2}' and so on are now no longer legal. This is no big loss because they were not useful anyway. This also changes the output of builtins.toXML for @-patterns slightly.
2009-10-22	* builtins.trace: in the common case that the value is a string, then	Eelco Dolstra	1	-1/+6
	show the string, not the ATerm, so we get `trace: bla' instead of `trace: Str("bla",[])'.
2009-10-21	* Added a primop unsafeDiscardOutputDependency needed by Disnix to	Eelco Dolstra	1	-3/+34
	pass derivation paths to a builder without actually building them.
2009-09-23	* tryEval shouldn't catch all exceptions of type Error, since not all	Eelco Dolstra	1	-2/+2
	of them leave the evaluator in a continuable state. Also, it should be less chatty.
2009-09-15	* Two primops: builtins.intersectAttrs and builtins.functionArgs.	Eelco Dolstra	1	-0/+66
	intersectAttrs returns the (right-biased) intersection between two attribute sets, e.g. every attribute from the second set that also exists in the first. functionArgs returns the set of attributes expected by a function. The main goal of these is to allow the elimination of most of all-packages.nix. Most package instantiations in all-packages.nix have this form: foo = import ./foo.nix { inherit a b c; }; With intersectAttrs and functionArgs, this can be written as: foo = callPackage (import ./foo.nix) { }; where callPackage = f: args: f ((builtins.intersectAttrs (builtins.functionArgs f) pkgs) // args); I.e., foo.nix is called with all attributes from "pkgs" that it actually needs (e.g., pkgs.a, pkgs.b and pkgs.c). (callPackage can do any other generic package-level stuff we might want, such as applying makeOverridable.) Of course, the automatically supplied arguments can be overriden if needed, e.g. foo = callPackage (import ./foo.nix) { c = c_version_2; }; but for the vast majority of packages, this won't be needed. The advantages are to reduce the amount of typing needed to add a dependency (from three sites to two), and to reduce the number of trivial commits to all-packages.nix. For the former, there have been two previous attempts: - Use "args: with args;" in the package's function definition. This however obscures the actual expected arguments of a function, which is very bad. - Use "{ arg1, arg2, ... }:" in the package's function definition (i.e. use the ellipis "..." to allow arbitrary additional arguments), and then call the function with all of "pkgs" as an argument. But this inhibits error detection if you call it with an misspelled (or obsolete) argument.
2009-08-25	Adding tryEval builtin. It allows to catch presence of errors in an expression.	Michael Raskin	1	-0/+18

2009-06-30	* Don't show trace information by default (`--show-trace' to enable).	Eelco Dolstra	1	-1/+1
	NixOS evaluation errors in particular look intimidating and generally aren't very useful. Ideally the builtins.throw messages should be self-contained.
2009-03-18	* Unify exportReferencesGraph and exportBuildReferencesGraph, and make	Eelco Dolstra	1	-12/+18
	sure that it works as expected when you pass it a derivation. That is, we have to make sure that all build-time dependencies are built, and that they are all in the input closure (otherwise remote builds might fail, for example). This is ensured at instantiation time by adding all derivations and their sources to inputDrvs and inputSrcs.
2009-02-05	added primop functions __isBool, __isString, __isInt	Marc Weber	1	-0/+25

2009-01-27	Add the "addErrorContext" builtin to add more information in the stack trace.	Nicolas Pierron	1	-0/+14

2008-12-04	(no commit message)	Eelco Dolstra	1	-3/+4

2008-12-04	* Dirty hack to make nix-push work properly on derivations: the	Eelco Dolstra	1	-8/+23
	derivation should be a source rather than a derivation dependency of the call to the NAR derivation. Otherwise the derivation (and all its dependencies) will be built as a side-effect, which may not even succeed.
