2009-04-21* Use foreach in a lot of places.Eelco Dolstra
2008-08-25* Strip off the `.nix' suffix from the attribute name for files inEelco Dolstra
~/.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 whenEelco Dolstra
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
2006-11-30* Refactoring. There is now an abstract interface class StoreAPIEelco Dolstra
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, stringEelco Dolstra
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
2006-09-04* Use a proper namespace.Eelco Dolstra
* Optimise header file usage a bit. * Compile the parser as C++.
2006-05-02* Removed a bunch of ATreverses.Eelco Dolstra
2005-01-25* Maintain the references/referers relation also for derivations.Eelco Dolstra
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
2005-01-20* Another change to low-level derivations. The last one this year, IEelco Dolstra
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
`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.
