9da367b7d5 * `nix-store -qR' and friends: print the paths sorted topologically
under the references relation.  This is useful for commands that
  want to copy paths to another Nix store in the right order.

43c4d18c6a * nix-store --import': import an archive created by nix-store
--export' into the Nix store, and optionally check the cryptographic
  signatures against /nix/etc/nix/signing-key.pub.  (TODO: verify
  against a set of public keys.)

b824a1daee * Start of `nix-store --export' operation for serialising a store
path.  This is like `nix-store --dump', only it also dumps the
  meta-information of the store path (references, deriver).  Will add
  a `--sign' flag later to add a cryptographic signature, which we
  will use for exchanging store paths between build farm machines in a
  secure manner.

b618fa6eb6 * computeStorePathForText: take the references into account when
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).

a3e6415ba8 * New primop builtins.filterSource, which can be used to filter files
from a source directory.  All files for which a predicate function
  returns true are copied to the store.  Typical example is to leave
  out the .svn directory:

    stdenv.mkDerivation {
      ...
      src = builtins.filterSource
        (path: baseNameOf (toString path) != ".svn")
        ./source-dir;
      # as opposed to
      #   src = ./source-dir;
    }

  This is important because the .svn directory influences the hash in
  a rather unpredictable and variable way.

a9c4f66cfb * Allow unprivileged users to run the garbage collector and to do
`nix-store --delete'.  But unprivileged users are not allowed to
  ignore liveness.
* `nix-store --delete --ignore-liveness': ignore the runtime roots as
  well.

29cf434a35 * The determination of the root set should be made by the privileged
process, so forward the operation.
* Spam the user about GC misconfigurations (NIX-71).
* findRoots: skip all roots that are unreadable - the warnings with
  which we spam the user should be enough.

74033a844f * Add indirect root registration to the protocol so that unprivileged
processes can register indirect roots.  Of course, there is still
  the problem that the garbage collector can only read the targets of
  the indirect roots when it's running as root...

e25fad691a * Move addTempRoot() to the store API, and add another function
syncWithGC() to allow clients to register GC roots without needing
  write access to the global roots directory or the GC lock.

a824d58b56 * Merge addToStore and addToStoreFixed.
* addToStore now adds unconditionally, it doesn't use readOnlyMode.
  Read-only operation is up to the caller (who can call
  computeStorePathForPath).

b0d8e05be1 * More operations.
* addToStore() and friends: don't do a round-trip to the worker if
  we're only interested in the path (i.e., in read-only mode).

0565b5f2b3 * More remote operations.
* Added new operation hasSubstitutes(), which is more efficient than
  querySubstitutes().size() > 0.

e2ef5e07fd * Refactoring. There is now an abstract interface class StoreAPI
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.
