75068e7d75 * Use a proper namespace.
* Optimise header file usage a bit.
* Compile the parser as C++.

9d72bf8835 * 64-bit compatibility fixes (for problems revealed by building on an Athlon
64 running 64-bit SUSE).  A patched ATerm library is required to run Nix
  succesfully.

0cb016c209 * Refactoring. Hope this doesn't break the semantics of `-u' ;-) 2005-02-14 16:16:02 +00:00

20ce2642fc * Refactoring to support different installation sources in nix-env.
* Set the references for the user environment manifest properly.
* Don't copy the manifest (this was accidental).
* Don't store derivation paths in the manifest (maybe this should be
  made optional).  This cleans up the semantics of nix-env, which were
  weird.
* Hash on the output paths of activated components, not on derivation
  paths.  This is because we don't know the derivation path of already
  installed components anymore, and it allows the installation of
  components by store path (skipping Nix expressions entirely).
* Query options `--out-path' and `--drv-path' to show the output and
  derivation paths of components, respectively (the latter replaces
  the `--expr' query).

c505702265 * Fix and simplify the garbage collector (it's still not concurrent,
though).  In particular it's now much easier to register a GC root.
  Just place a symlink to whatever store path it is that you want to
  keep in /nix/var/nix/gcroots.

863dcff6c5 * Started removing closure store expressions, i.e., the explicit
representation of closures as ATerms in the Nix store.  Instead, the
  file system pointer graph is now stored in the Nix database.  This
  has many advantages:

  - It greatly simplifies the implementation (we can drop the notion
    of `successors', and so on).

  - It makes registering roots for the garbage collector much easier.
    Instead of specifying the closure expression as a root, you can
    simply specify the store path that must be retained as a root.
    This could not be done previously, since there was no way to find
    the closure store expression containing a given store path.
    
  - Better traceability: it is now possible to query what paths are
    referenced by a path, and what paths refer to a path.

dcc433de47 * Operation `--delete-generations' to delete generations of a
profile.  Arguments are either generation number, or `old' to delete
  all non-current generations.  Typical use:

  $ nix-env --delete-generations old
  $ nix-collect-garbage

* istringstream -> string2Int.

00fe1a506f * When creating a new generation, also make the normal form of the
derivation (i.e., the closure store expression) a root of the
  garbage collector.  This ensures that running `nix-collect-garbage
  --no-successors' is safe.
