Add the contents of FILE-NAME under BASENAME to the store and return its store file name. When RECURSIVE? is false, FILE-NAME must designate a regular file--not a directory nor a symlink. When RECURSIVE? is true and FILE-NAME designates a directory, the contents of FILE-NAME are added recursively; if FILE-NAME designates a flat file and RECURSIVE? is true, its contents are added, and its permission bits are kept. HASH-ALGO must be a string such as "sha256".

When RECURSIVE? is true, call (SELECT? FILE STAT) for each directory entry, where FILE is the entry's absolute file name and STAT is the result of 'lstat'; exclude entries for which SELECT? does not return true.

Return the info (hash, references, etc.) for PATH.

Return the list of dead store paths---i.e., store paths no longer referenced, and thus subject to being garbage-collected.

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 the build log file for DRV, a derivation file name, or #f if it could not be found.

Return the hash part of PATH as a base32 string, or #f if PATH is not a syntactically valid store path.

Return a procedure of two arguments to record cache lookups, hits, and misses for COMPONENT. The procedure must be passed a Boolean indicating whether the cache lookup was a hit, and the actual cache (a vhash).

Delete PATHS from the store at SERVER, if they are no longer referenced. If MIN-FREED is non-zero, then stop after at least MIN-FREED bytes have been collected. Return the paths that were collected, and the number of bytes freed.

Convert MAPPING, an alist like:

(("guix/build/utils.scm" . "…/utils.scm"))

to a tree suitable for 'add-file-tree-to-store' and 'interned-file-tree'.

Return the list of outputs of PATH, a .drv file.

Export the store paths listed in PATHS to PORT, in topological order, signing them if SIGN? is true. When RECURSIVE? is true, export the closure of PATHS---i.e., PATHS and all their dependencies.

START, PROGRESS, and FINISH are used to track progress of the data transfer. START is a one-argument that is passed the list of store items that will be transferred; it returns values that are then used as the initial state threaded through PROGRESS calls. PROGRESS is passed the store item about to be sent, along with the values previously return by START or by PROGRESS itself. FINISH is called when the last store item has been called.

Return information about the subset of PATHS that is substitutable. For each substitutable path, a `substitutable?' object is returned; thus, the resulting list can be shorter than PATHS. Furthermore, that there is no guarantee that the order of the resulting list matches the order of PATHS.

Ensure that the given path is valid; if it is not valid, it may be made valid by running a substitute. Return #t on success and raise an exception on failure.

As a GC root is not created by the daemon, you may want to call 'add-temp-root' on that store path.

Return the SHA256 hash of the nar serialization of PATH as a bytevector.
