it by always all outputs.
(graft-derivation): Fix calls of cumulative-grafts.
* tests/grafts.scm (graft-derivation with #:outputs): Remove.
(graft-derivation, no applicable grafts): Add.
(graft-derivation, unused outputs not depended on): Remove.
(graft-derivation, multi-output graft determinism): Add.
(graft-derivation, consistent cache keys): Add.

Fixes a bug that would occur with references to two outputs of the same
derivation, with one of them referring to the other one.

For example, the references of libreoffice include both mariadb:dev and
mariadb:lib; additionally, mariadb:dev refers to mariadb:lib.  In this
case, the glibc graft would not be applied on one of the mariadb paths,
and both the grafted and ungrafted glibc would end up in the closure of
libreoffice.

Fixes <https://issues.guix.gnu.org/66662>.

* guix/grafts.scm (non-self-references): Simplify and include references
to outputs of DRV other than OUTPUTS.
(reference-origins): Simplify and possibly return outputs of DRV itself.
(cumulative-grafts)[graft-origin?]: Add OUTPUT parameter and honor it.
[dependency-grafts]: Adjust accordingly.
* tests/grafts.scm ("graft-derivation, multiple outputs need to be replaced"):
New test.

Reported by Leo Famulari <leo@famulari.name>.

* guix/build/graft.scm (replace-store-references): When I >= END, check
whether WRITTEN > END and call 'get-bytevector-n!' when it is.
* tests/grafts.scm (buffer-size): New variable.
("replace-store-references, <http://bugs.gnu.org/28212>"): New test.

Fixes <http://bugs.gnu.org/24886>.

Previously, the grafting derivation of, say, brdf-explorer would pull in
qt:doc even though brdf-explorer depends only on qt:out, not qt:doc.

* guix/grafts.scm (with-cache): Use 'vhash-assoc' and 'vhash-cons'
instead of 'vhash-assq' and 'vhash-consq'.
(cumulative-grafts): Pass #:outputs to 'graft-derivation/shallow'.  Use
OUTPUTS instead of (derivation-output-names drv).
(graft-derivation): Add #:outputs parameter; pass it to
'cumulative-grafts'.
* tests/grafts.scm (make-derivation-input): New variable.
("graft-derivation, replaced derivation has multiple outputs"): Make
sure P2:zzz is not part of the outputs of P3D.
("graft-derivation with #:outputs")
("graft-derivation, unused outputs not depended on"): New tests.
