| 2021-09-25 | gexp: Leave grafting as is when lowering allowed/disallowed references....Fixes <https://issues.guix.gnu.org/50676>.
Reported by Mathieu Othacehe <othacehe@gnu.org>.
Commit a779363b6aa581e88eda21f9f35530962d54ac25 was partially incorrect:
references passed to #:allowed-references or #:references-graphs *can*
be lowered as references to grafted elements. This is for example the
case when doing:
(computed-file "partition.img" exp
#:options `(#:references-graphs ,inputs))
Here INPUTS must be lowered as a reference to suitably grafted elements.
Failing to do that, the reference graph will not match the actual
INPUTS.
However, when building a package, those references must indeed refer
only to ungrafted packages. This commit preserves that by having build
systems pass #:graft? #f.
* guix/gexp.scm (lower-reference-graphs, lower-references): Remove uses
of 'without-grafting'. This reverts
a779363b6aa581e88eda21f9f35530962d54ac25.

| 2021-07-05 | build-system/trivial: Honor build inputs when cross-compiling....Fixes a regression introduced in
7d873f194ca69d6096d28d7a224ab78e83e34fe1 whereby host inputs would be
