Return the package name part of PATH, a file name in the store.

Return the list of path that refer to PATH.

Return the subset of PATHS that is substitutable.

Connect to the daemon at URI (a string), or, if PORT is not #f, use it as the I/O port over which to communicate to a build daemon.

When RESERVE-SPACE? is true, instruct it to reserve a little bit of extra space on the file system so that the garbage collector can still operate, should the disk become full. When CPU-AFFINITY is true, it must be an integer corresponding to an OS-level CPU number to which the daemon's worker process for this connection will be pinned. If NON-BLOCKING?, use a non-blocking socket when using the file, unix or guix URI schemes. If BUILT-IN-BUILDERS is provided, it should be a list of strings and this will be used instead of the builtin builders provided by the build daemon. Return a server object.

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

Return an output path for the fixed output OUTPUT defined by HASH of type HASH-ALGO, of the derivation NAME. RECURSIVE? has the same meaning as for 'add-to-store'.

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

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).

Collect garbage from the store at SERVER. If MIN-FREED is non-zero, then collect at least MIN-FREED bytes. Return the paths that were collected, and the number of bytes freed.

Return the names of the supported built-in derivation builders supported by STORE.

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

Return the list of references of PATH.

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

Return the narinfos for PATHS, invoking the server at CACHE when no information is available locally.

Look up narinfos for PATHS on all of CACHES, a list of URLS, in that order. That is, when a cache lacks an AUTHORIZED? narinfo, look it up in the next cache, and so on.

Return a list of narinfos for PATHS or a subset thereof. The returned narinfos are either AUTHORIZED?, or they claim a hash that matches an AUTHORIZED? narinfo.
