Fixes <https://bugs.gnu.org/30155>.
The effect can be seen in the package graph produced by:
guix graph -e '(@@ (gnu packages commencement) static-bash-for-glibc)'
This reduces the number of "duplicate" nodes in this graph, i.e.,
distinct package objects that correspond to the same derivation (objects
that are not 'eq?' but semantically equal.)
* gnu/packages/commencement.scm (linux-libre-headers-boot0): Make an
'mlambda' instead of a 'lambda'.
(hurd-core-headers-boot0): Ditto.
'package-grafts' returns a list of potentially applicable grafts, which
'cumulative-grafts' then narrows by looking at store item references and
determining the subset of the grafts that's actually applicable.
Until now, 'package-grafts' would traverse native inputs and would thus
return a large superset of the applicable grafts, since native inputs
are not in the reference graph by definition. This patch fixes that by
having 'package-grafts' ignore entirely native inputs from the
dependency graph.
* guix/packages.scm (fold-bag-dependencies)[bag-direct-inputs*]: Add
special case for libc.
* guix/packages.scm (bag-grafts)[native-grafts, target-grafts]: Remove.
[grafts]: New procedure.
Use it.
* tests/packages.scm ("package-grafts, grafts of native inputs
ignored"): New test.
Previously recursive calls to 'loop' would always consider all the bag
inputs rather than those corresponding to NATIVE?.
* guix/packages.scm (fold-bag-dependencies)[bag-direct-inputs*]: New
procedure. Use it both in the 'match' expression and in its body.
This avoids repeated deprecation messages, particularly while running
'guix system build' or similar.
* guix/gexp.scm (gexp->derivation): Add #:deprecation-warnings. Pass it
to 'compiled-modules'.
(compiled-modules): Add #:deprecation-warnings and honor it.
* doc/guix.texi (G-Expressions): Update 'gexp->derivation'
documentation.
* guix/packages.scm (patch-and-repack): Pass #:deprecation-warnings #t.
Works around <https://bugs.gnu.org/28211>.
Reported by Marius Bakke <mbakke@fastmail.com>.
* guix/packages.scm (guile-2.0): New procedure.
(package-derivation, package-cross-derivation): Use it when computing
the #:guile argument to 'graft-derivation'.
This provides a ~2x speedup when using 4 threads.
* guix/packages.scm (patch-and-repack)[build]: Invoke xz with
'--threads=0' when re-packing tarballs.
* guix/packages.scm (package-mapping): New procedure.
(package-input-rewriting): Rewrite in terms of 'package-mapping'.
* tests/packages.scm ("package-mapping"): New test.
* doc/guix.texi (Defining Packages): Document it.

* guix/packages.scm (expand-input): Add 'guard' form around call to
'package-source-derivation'.
* tests/packages.scm (dummy): New test.
* guix/packages.scm (package-upstream-name): New procedure.
* guix/gnu-maintenance.scm (gnu-package?, ftp-server/directory)
(latest-release*, latest-gnome-release)
(latest-kde-release): Use it instead of the inline expression.
This provides a way to mark a package as superseded by another one.
Upgrades replace superseded packages with their replacement.
* guix/packages.scm (package-superseded, deprecated-package): New
procedures.
* gnu/packages.scm (%find-package): Check for 'package-superseded'.
* guix/scripts/package.scm (transaction-upgrade-entry)[supersede]: New
procedure. Call it when 'package-superseded' is true.
* tests/guix-build.sh: Add test for a superseded package.
* tests/packages.scm ("package-superseded")
("transaction-upgrade-entry, superseded package"): New tests.

* guix/packages.scm (patch-and-repack)[build]: Use
'--no-backup-if-mismatch' patch flag to avoid making *.orig files.
The two mistakes made here (confusion between 'modules' and
'imported-modules') were canceling each other.
* guix/packages.scm (patch-and-repack): Use IMPORTED-MODULES, not
MODULES, as the base of the module list passed as #:modules to
'gexp->derivation'.
(origin->derivation): Pass IMPORTED-MODULES, not MODULES, as
the #:imported-modules argument of 'patch-and-repack'.
* gnu/packages/engineering.scm (fastcap)[source]: Add 'imported-modules'
field.
* guix/packages.scm (origin->derivation): Rename 'source' parameter to
'origin'. Move cases where SOURCE is a string to...
(package-source-derivation): ... here.
This reduces the wall-clock time of
guix environment gnutls --pure -E true
by ~35%.
* guix/packages.scm (%graft-cache): New variable.
(input-graft): Use 'cached' to cache to %GRAFT-CACHE.
This reduces the wall-clock time of
guix environment gnutls --pure -E true
by ~25%.
* guix/packages.scm (%bag-cache): New variable.
(package->bag): Use 'cached' to cache things to %BAG-CACHE.
* guix/packages.scm (cache): Rename to...
(cache!): ... this. Add 'cache' parameter, and use it.
(cached): Add a rule to allow the cache to be specified.
Fixes <http://bugs.gnu.org/22139>.
* guix/grafts.scm (graft-derivation): Rename to...
(graft-derivation/shallow): ... this.
(graft-origin-file-name, item->deriver, non-self-references)
(cumulative-grafts, graft-derivation): New procedures
* tests/grafts.scm ("graft-derivation, grafted item is a direct
dependency"): Clarify title. Use 'grafted' instead of 'graft' to refer
to the grafted derivation.
("graft-derivation, grafted item is an indirect dependency")
("graft-derivation, no dependencies on grafted output"): New tests.
* guix/packages.scm (input-graft): Change to take a package instead of
an input.
(input-cross-graft): Likewise.
(fold-bag-dependencies): New procedure.
(bag-grafts): Rewrite in terms of 'fold-bag-dependencies'.
* tests/packages.scm ("package-derivation, indirect grafts"): Comment out.
* doc/guix.texi (Security Updates): Mention run-time dependencies and
recursive grafting.
* guix/packages.scm <package>: Use '@' in record printer.
* guix/import/cabal.scm <cabal-package>: Likewise
* guix/import/elpa.scm <elpa-package>: Likewise.
* tests/packages.scm: Adapt to it.
* guix/packages.scm (package-transitive-native-search-paths): New
procedure.
* tests/packages.scm ("package-transitive-native-search-paths"): New
test.
