packages: 'package-input-rewriting/spec' can rewrite implicit dependencies.
With this change, '--with-input', '--with-graft', etc. also apply to implicit dependencies. Thus, it's now possible to do: guix build python-itsdangerous --with-input=python-wrapper=python@2 or: guix build hello --with-graft=glibc=glibc@2.29 Additionally, before, implicit inputs were not rewritten, which could lead to duplicates in the output of 'bag-transitive-inputs' (packages that are not 'eq?' but lead to the same derivation). This in turn would lead to unnecessary rebuilds when using '--with-input' & co. This change fixes it by ensuring even implicit inputs are rewritten. Fixes <https://bugs.gnu.org/42156>. * guix/packages.scm (package-input-rewriting/spec): Add #:deep? defaulting to #true, and pass it to 'package-mapping'. [replacement-property]: New variable. [rewrite]: Check that property and set it on the result of PROC. [cut?]: New procedure. * tests/packages.scm ("package-input-rewriting/spec"): Ensure implicit inputs were unchanged. ("package-input-rewriting/spec, partial match"): Pass #:deep? #f. ("package-input-rewriting/spec, deep") ("package-input-rewriting/spec, no duplicates"): New tests. (package/inherit): Move before use. * tests/guix-build.sh: Add tests. * tests/scripts-build.scm ("options->transformation, with-graft"): Compare dependencies by package name or derivation file name. * doc/guix.texi (Defining Packages): Adjust accordingly.
