2005-07-22	* Build dynamic libraries.	Eelco Dolstra

2005-07-12	* In nix-instantiate, at top-level, call functions that have arguments	Eelco Dolstra
	with default values automatically. I.e., e -> e {}. This feature makes convenience expressions such as pkgs/system/i686-linux.nix in Nixpkgs obsolete, since we can just do $ nix-instantiate ./pkgs/system/all-packages.nix since all-packages.nix takes a single argument (system) that has a default value (__thisSystem).
2005-02-01	* nix-build: use an indirection scheme to make it easier for users to	Eelco Dolstra
	get rid of GC roots. Nix-build places a symlink `result' in the current directory. Previously, removing that symlink would not remove the store path being linked to as a GC root. Now, the GC root created by nix-build is actually a symlink in `/nix/var/nix/gcroots/auto' to `result'. So if that symlink is removed the GC root automatically becomes invalid (since it can no longer be resolved). The root itself is not automatically removed - the garbage collector should delete dangling roots.
2005-02-01	* nix-store, nix-instantiate: added an option `--add-root' to	Eelco Dolstra
	immediately add the result as a permanent GC root. This is the only way to prevent a race with the garbage collector. For instance, the old style ln -s $(nix-store -r $(nix-instantiate foo.nix)) \ /nix/var/nix/gcroots/result has two time windows in which the garbage collector can interfere (by GC'ing the derivation and the output, respectively). On the other hand, nix-store --add-root /nix/var/nix/gcroots/result -r \ $(nix-instantiate --add-root /nix/var/nix/gcroots/drv \ foo.nix) is safe. * nix-build: use `--add-root' to prevent GC races.
2005-01-19	* Renamed `normalise.cc' -> `build.cc', `storeexprs.cc' ->	Eelco Dolstra
	`derivations.cc', etc. * Store the SHA-256 content hash of store paths in the database after they have been built/added. This is so that we can check whether the store has been messed with (a la `rpm --verify'). * When registering path validity, verify that the closure property holds.
2004-11-12	* Document --eval-only and --parse-only options in nix-instantiate.	Eelco Dolstra

2004-10-29	* Drop ATmake / ATMatcher also in handling store expressions.	Eelco Dolstra

2004-10-26	* Don't use ATmake / ATmatch anymore, nor the ATMatcher class.	Eelco Dolstra
	Instead we generate data bindings (build and match functions) for the constructors specified in `constructors.def'. In particular this removes the conversions between AFuns and strings, and Nix expression evaluation now seems 3 to 4 times faster.
2004-10-26	* Mode `--parse-only' to parse the input (on stdin, `-'), and print	Eelco Dolstra
	out the AST as an ATerm. * Mode `--eval-only' to parse and evaluate the input, and print the resulting normal form as an ATerm. Neither of these modes require store/DB write permission.
2004-07-01	* Nix-instantiate now accepts sets of derivations (just like nix-env).	Eelco Dolstra

2004-04-05	* When something goes wrong in the evaluation of a Nix expression,	Eelco Dolstra
	print a nice backtrace of the stack, rather than vomiting a gigantic (and useless) aterm on the screen. Example: error: while evaluating file `.../pkgs/system/test.nix': while evaluating attribute `subversion' at `.../pkgs/system/all-packages-generic.nix', line 533: while evaluating function at `.../pkgs/applications/version-management/subversion/default.nix', line 1: assertion failed at `.../pkgs/applications/version-management/subversion/default.nix', line 13 Since the Nix expression language is lazy, the trace may be misleading. The purpose is to provide a hint as to the location of the problem.
2004-02-16	* Allow linking against an external Berkeley DB / ATerm library.	Eelco Dolstra

2004-02-04	* Use a map to lookup primops.	Eelco Dolstra
	* Various performance improvements in the evaluator. * Do not link against unused (and missing!) libraries (-lsglr, etc.).
2003-12-02	* Add missing files to `make dist'.	Eelco Dolstra

2003-12-01	* Help text for all (non-script) programs, so no more:	Eelco Dolstra
	$ nix-instantiate --help error: unknown flag `--help` Try `nix-instantiate --help' for more information. :-)
2003-11-22	* Fix nix-push.	Eelco Dolstra

2003-11-22	* Maintain integrity of the substitute and successor mappings when	Eelco Dolstra
	deleting a path in the store. * Allow absolute paths in Nix expressions. * Get nix-prefetch-url to work again. * Various other fixes.
2003-11-19	* Refactoring (step 2).	Eelco Dolstra

2003-11-19	* Refactoring: put the Nix expression evaluator in its own library so	Eelco Dolstra
	that it can be used by multiple programs.
2003-11-19	* Use `sdftable -s' to get warnings about the grammar.	Eelco Dolstra
	* Several bug fixes in the grammar. * Allow one-line comments (#... and //...) to end in EOF.
2003-11-18	* "Fix expression" -> "Nix expression".	Eelco Dolstra
	* More refactoring.
2003-11-18	* nix -> nix-store, fix -> nix-instantiate.	Eelco Dolstra

2003-03-24	* Descriptors now have a "system" field specifying the platform that	Eelco Dolstra
	the build or run action should be perfomed on. This ensures that descriptors have different hashes on different platforms.
2003-03-21	* Fetch sources from the network.	Eelco Dolstra

2003-03-20	* nix-instantiate now instantiantes the closure of the set of	Eelco Dolstra
	descriptor templates under the import relation. I.e., we can now say: nix-instantiate outdir foo.nix which will create descriptors for foo.nix and all imported packages in outdir/.
2003-03-20	* A script to instantiate package descriptors from templates.	Eelco Dolstra
