This allows substitutes to be downloaded from unauthorized servers, as
long as they advertise the same hash and references as one of the
authorized servers.
* guix/scripts/substitute.scm (assert-valid-narinfo): Remove.
(valid-narinfo?): Add #:verbose?. Handle each case of
'signature-case'.
(equivalent-narinfo?): New procedure.
(lookup-narinfos/diverse): Add 'authorized?' parameter and honor it.
[select-hit]: New procedure.
(lookup-narinfo): Add 'authorized?' parameter and pass it.
(process-query): Adjust callers accordingly.
(process-substitution): Remove call to 'assert-valid-narinfo'. Check
whether 'lookup-narinfo' returns true and call 'leave' if not.
* tests/substitute.scm (%main-substitute-directory)
(%alternate-substitute-directory): New variables.
(call-with-narinfo): Make 'narinfo-directory' a parameter. Call
'mkdir-p' to create it. Change unwind handler to check whether
CACHE-DIRECTORY exists before deleting it.
(with-narinfo*): New macro.
("substitute, no signature")
("substitute, invalid hash")
("substitute, unauthorized key"): Change expected error message to "no
valid substitute".
("substitute, unauthorized narinfo comes first")
("substitute, unsigned narinfo comes first")
("substitute, first narinfo is unsigned and has wrong hash")
("substitute, first narinfo is unsigned and has wrong refs")
("substitute, unsigned narinfo comes first")
("substitute, two invalid narinfos"): New tests.
* doc/guix.texi (Substitutes): Explain the new behavior.
* guix/scripts/substitute.scm (%cache-urls): Rename to...
(%default-substitute-urls): ... this.
(substitute-urls): New variable.
(guix-substitute): Use it instead of %CACHE-URLS.
* tests/substitute.scm: Likewise.
Before that '.log' files for scheme tests were fragmented and not
included in test-suite.log. This unifies the semantics of SRFI-64 API
with Automake test suite.
* build-aux/test-driver.scm: New file.
* Makefile.am (SCM_LOG_DRIVER, AM_SCM_LOG_DRIVER_FLAGS): New variables.
(SCM_LOG_COMPILER, AM_SCM_LOG_FLAGS): Delete variables.
(AM_TESTS_ENVIRONMENT): Set GUILE_AUTO_COMPILE to 0.
* test-env.in: Silence guix-daemon.
* doc/guix.texi (Running the Test Suite): Describe how to display the
detailed results. Bug reports require only 'test-suite.log' file.

* tests/containers.scm: Likewise. Use 'test-skip' instead of exiting
with error code 77.
* guix/scripts/substitute.scm (lookup-narinfos/diverse): New procedure.
(lookup-narinfo): Use it.
(process-query): Change #:cache-url to #:cache-urls.
[valid?]: Remove 'narinfo?' check, which is no longer necessary.
Use 'lookup-narinfos/diverse' instead of 'lookup-narinfos'.
(process-substitution): Change #:cache-url to #:cache-urls.
(%cache-url): Rename to...
