Add BYTES 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 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'.

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

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

Return the store path for NAME/HASH/TYPE.

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'.

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

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 name of FILE once interned in the store. Use NAME as its store name, or the basename of FILE if NAME is omitted.

When RECURSIVE? is true, the contents of FILE are added recursively; if FILE designates a flat file and RECURSIVE? is true, its contents are added, and its permission bits are kept.

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 list of path that refer to PATH.

Close the connection to SERVER.

Assimilate PORT, an input/output port, and return a connection to the daemon, assuming the given protocol VERSION. 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.

Warning: this procedure assumes that the initial handshake with the daemon has already taken place on PORT and that we're just continuing on this established connection. Use with care.

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.
