History

daemon: Let 'guix substitute' perform hash checks. 
This way, the hash of the store item can be computed as it is restored,
thereby avoiding an additional file tree traversal ('hashPath' call)
later on in the daemon.  Consequently, it should reduce latency between
subsequent substitute downloads.

This is a followup to 5ff521452b.

* guix/scripts/substitute.scm (narinfo-hash-algorithm+value): New
procedure.
(process-substitution): Wrap INPUT into a hash input port, 'hashed', and
read from it.  Compare the actual and expected hashes, and print a
"hash-mismatch" status line when they differ.  When they match, print
not just "success" but also the nar hash and size.
* nix/libstore/build.cc (class SubstitutionGoal)[expectedHashStr]:
Remove.
(SubstitutionGoal::finished): Tokenize 'status'.  Parse it and handle
"success" and "hash-mismatch" accordingly.  Call 'hashPath' only when
the returned hash is not SHA256.
(SubstitutionGoal::handleChildOutput): Remove 'expectedHashStr'
handling.
* tests/substitute.scm ("substitute, invalid hash"): Rename to...
("substitute, invalid narinfo hash"): ... this.
("substitute, invalid hash"): New test.
