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

Return the subset of PATHS that is substitutable.

Return the cache of STORE identified by CACHE, an identifier as returned by 'allocate-store-connection-cache'.

Remove the permanent garbage collector root pointing to TARGET. Raise an error if there is no such root.

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 build log file for FILE, or #f if none could be found. FILE must be an absolute store file name, or a derivation file name.

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

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

Return the list of currently configured substitutes URLs for STORE, or #f if the daemon is too old and does not implement this RPC.

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

Add TEXT under file NAME in the store, and return its store path. REFERENCES is the list of store paths referred to by the resulting store path.

Return #t when PATH designates a valid store item and #f otherwise (an invalid item may exist on disk but still be invalid, for instance because it is the result of an aborted or failed build.)

A '&store-protocol-error' condition is raised if PATH is not prefixed by the store directory (/gnu/store).
