| 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.

| 2021-03-03 | gexp: #:references-graphs refers to non-native derivations....Fixes a regression introduced in
c6d6aee6659acb293eb33f498fdac3b47a19a48, where #:reference-graphs would
end up referring to native inputs.
This would notably break the compilation of systems using a childhurd,
because they would attempt to build the 'hurd' package natively.
