Connect to the SSH daemon at URI, a URI object with the 'ssh' scheme.

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).

Monadic version of 'query-path-info' that returns #f when ITEM is not in the store.

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.

Return as a monadic value the absolute file name in the store of the file containing TEXT, a string. REFERENCES is a list of store items that the resulting text file refers to; it defaults to the empty list.

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

Return the list of store items for which a build failure is cached.

The result is always the empty list unless the daemon was started with '--cache-failures'.

Remove ITEMS from the list of cached build failures.

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

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

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

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

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

Lift PROC, a procedure whose first argument is a connection to the store, in the store monad.

Set STORE's CACHE to VALUE.

This is a mutating version that should be avoided. Prefer the functional 'set-store-connection-cache' instead, together with using %STORE-MONAD.

Return a list of root/target pairs: for each pair, the first element is the GC root file name and the second element is its target in the store.

When talking to a local daemon, this operation is equivalent to the 'gc-roots' procedure in (guix store roots), except that the 'find-roots' excludes potential roots that do not point to store items.
