2006-05-02 * Removed a bunch of ATreverses.Eelco Dolstra1-16/+19
2005-01-25 * Maintain the references/referers relation also for derivations.Eelco Dolstra1-1/+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 Dolstra1-1/+1
2005-01-20 * Another change to low-level derivations. The last one this year, IEelco Dolstra1-11/+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 Dolstra1-0/+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.
