Return a copy of STORE where CACHE has the given VALUE. CACHE must be a value returned by 'allocate-store-connection-cache'.

Lower PROC, a monadic procedure in %STORE-MONAD, to a "normal" procedure taking the store as its first argument.

Return #t if PATH is a store path, and not a sub-directory of a store path. This predicate is sometimes needed because files *under* a store path are not valid inputs.

Remove ITEMS from the list of cached build failures.

This makes sense only when the daemon was started with '--cache-failures'.

Return a list containing PATHS and all their references sorted in topological order.

Return the requisites of PATHS, including PATHS---i.e., their closures (all its references, recursively).

Import the set of store paths read from PORT into SERVER's store. An error is raised if the set of paths read from PORT is not signed (as per 'export-path #:sign? #t'.) Return the list of store paths imported.

Return the subset of PATHS that is substitutable.

Return an output path for OUTPUT (the name of the output as a string) of the derivation called NAME with hash HASH.

Return the list of live store paths---i.e., store paths still referenced, and thus not subject to being garbage-collected.
