2016-02-04 Eliminate the "store" global variableEelco Dolstra1-1/+1
Also, move a few free-standing functions into StoreAPI and Derivation. Also, introduce a non-nullable smart pointer, ref<T>, which is just a wrapper around std::shared_ptr ensuring that the pointer is never null. (For reference-counted values, this is better than passing a "T&", because the latter doesn't maintain the refcount. Usually, the caller will have a shared_ptr keeping the value alive, but that's not always the case, e.g., when passing a reference to a std::thread via std::bind.)

2015-05-06 nix-collect-garbage: Fix deleting old generationsWilliam A. Kennington III1-1/+1
The call to nix-env expects a string which represents how old the derivations are or just "old" which means any generations other than the current one in use. Currently nix-collect-garbage passes an empty string to nix-env when using the -d option. This patch corrects the call to nix-env such that it follows the old behavior.
