2010-04-21	* Don't use an ostringstream in unparseDerivation(), because it's	Eelco Dolstra	1	-38/+39
	slow. A `nix-env -qa --drv-path \*' on Nixpkgs was spending 40% of its time in unparseDerivation() because of this (now 11%).
2010-04-19	* Don't use the ATerm library for parsing/printing .drv files.	Eelco Dolstra	1	-110/+113

2009-04-21	* Use foreach in a lot of places.	Eelco Dolstra	1	-2/+1

2008-08-25	* Strip off the `.nix' suffix from the attribute name for files in	Eelco Dolstra	1	-3/+2
	~/.nix-defexpr, otherwise the attribute cannot be selected with the `-A' option. Useful if you want to stick a Nix expression directly in ~/.nix-defexpr.
2007-01-29	* computeStorePathForText: take the references into account when	Eelco Dolstra	1	-1/+1
	computing the store path (NIX-77). This is an important security property in multi-user Nix stores. Note that this changes the store paths of derivations (since the derivation aterms are added using addTextToStore), but not most outputs (unless they use builtins.toFile).
2006-12-01	* Replace read-only calls to addTextToStore.	Eelco Dolstra	1	-2/+6

2006-11-30	* Refactoring. There is now an abstract interface class StoreAPI	Eelco Dolstra	1	-2/+2
	containing functions that operate on the Nix store. One implementation is LocalStore, which operates on the Nix store directly. The next step, to enable secure multi-user Nix, is to create a different implementation RemoteStore that talks to a privileged daemon process that uses LocalStore to perform the actual operations.
2006-10-16	* Big cleanup of the semantics of paths, strings, contexts, string	Eelco Dolstra	1	-12/+2
	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'.)
2006-09-04	* Remove unnecessary inclusions of aterm2.h.	Eelco Dolstra	1	-0/+1

2006-09-04	* Use a proper namespace.	Eelco Dolstra	1	-1/+6
	* Optimise header file usage a bit. * Compile the parser as C++.
2006-05-02	* Removed a bunch of ATreverses.	Eelco Dolstra	1	-16/+19

2005-01-25	* Maintain the references/referers relation also for derivations.	Eelco Dolstra	1	-1/+9
	This simplifies garbage collection and `nix-store --query --requisites' since we no longer need to treat derivations specially. * Better maintaining of the invariants, e.g., setReferences() can only be called on a valid/substitutable path.
2005-01-20	* Terminology fixes.	Eelco Dolstra	1	-1/+1

2005-01-20	* Another change to low-level derivations. The last one this year, I	Eelco Dolstra	1	-11/+30
	promise :-) This allows derivations to specify on what output paths of input derivations they are dependent. This helps to prevent unnecessary downloads. For instance, a build might be dependent on the `devel' and `lib' outputs of some library component, but not the `docs' output.
2005-01-19	* Renamed `normalise.cc' -> `build.cc', `storeexprs.cc' ->	Eelco Dolstra	1	-0/+142
	`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.
