2006-09-05 * Missing #include.Eelco Dolstra1-0/+2
2006-09-04 * Use a proper namespace.Eelco Dolstra1-2/+6
* Optimise header file usage a bit. * Compile the parser as C++.
2005-02-14 * Refactoring. Hope this doesn't break the semantics of `-u' ;-)Eelco Dolstra1-1/+1
2005-01-19 * Started removing closure store expressions, i.e., the explicitEelco Dolstra1-2/+1
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.
2004-09-10 * Operation `--delete-generations' to delete generations of aEelco Dolstra1-0/+2
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.
2004-02-11 * When creating a new generation, also make the normal form of theEelco Dolstra1-1/+2
derivation (i.e., the closure store expression) a root of the garbage collector. This ensures that running `nix-collect-garbage --no-successors' is safe.
2004-02-08 * A command `--switch-generation' to switch to a specific generationEelco Dolstra1-0/+8
of the current profile, e.g., $ nix-env --list-generations ... 39 2004-02-02 17:53:53 40 2004-02-02 17:55:18 41 2004-02-02 17:55:41 42 2004-02-02 17:55:50 (current) $ nix-env --switch-generation 39 $ ls -l /nix/var/nix/profiles/default ... default -> default-39-link * Also a command `--rollback' which is just a convenience operation to rollback to the oldest generation younger than the current one. Note that generations properly form a tree. E.g., if after switching to generation 39, we perform an installation action, a generation 43 is created which is a descendant of 39, not 42. So a rollback from 43 ought to go back to 39. This is not currently implemented; generations form a linear sequence.
2004-02-06 * In `--list-generations', show what the current generation is.Eelco Dolstra1-1/+1
2004-02-06 * A command `--list-generations' to show all generations for aEelco Dolstra1-0/+14
profile.
2004-02-06 * More refactoring.Eelco Dolstra1-0/+14
