* guix/grafts.scm (graft-derivation/shallow): Pass #:properties to
'build-expression->derivation'.
* tests/grafts.scm ("graft-derivation, grafted item is a direct
dependency"): Check the value returned by 'derivation-properties'.
This leads to ~25% improvements on things like:
guix system build desktop.tmpl --no-grafts -d
* guix/store.scm (<nix-server>)[object-cache]: New field.
* guix/store.scm (open-connection): Initialize it.
(cache-object-mapping, lookup-cached-object, %mcached): New procedures.
(mcached): New macro.
* guix/gexp.scm (lower-object): Use it.
* guix/grafts.scm (grafting?): New procedure.
Fixes <https://bugs.gnu.org/19973>.
Reported by Mark H Weaver <mhw@netris.org>.
* guix/build/debug-link.scm: New file.
* guix/build/graft.scm (%graft-hooks): New variable.
(graft): Add #:hooks and honor it.
* guix/grafts.scm (graft-derivation/shallow): Add (guix build
debug-link) and (guix elf) to #:modules.
* tests/debug-link.scm: New file.
* Makefile.am (MODULES): Add guix/build/debug-link.scm.
(SCM_TESTS): Add tests/debug-link.scm.
This avoids the open/fstat/close syscalls upon a cache hit that we had
with the previous idiom:
(call-with-input-file file read-derivation)
where caching happened in 'read-derivation' itself.
* guix/derivations.scm (%read-derivation): Rename to...
(read-derivation): ... this.
(read-derivation-from-file): New procedure.
(derivation-prerequisites, substitution-oracle)
(derivation-prerequisites-to-build):
(derivation-path->output-path, derivation-path->output-paths):
(derivation-path->base16-hash, map-derivation): Use
'read-derivation-from-file' instead of (call-with-input-file …
read-derivation).
* guix/grafts.scm (item->deriver): Likewise.
* guix/scripts/build.scm (log-url, options->things-to-build): Likewise.
* guix/scripts/graph.scm (file->derivation): Remove.
(derivation-dependencies, %derivation-node-type): Use
'read-derivation-from-file' instead.
* guix/scripts/offload.scm (guix-offload): Likewise.
* guix/scripts/perform-download.scm (guix-perform-download): Likewise.
* guix/scripts/publish.scm (load-derivation): Remove.
(narinfo-string): Use 'read-derivation-from-file'.
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.
Before this commit, we'd lose the cache across recursive calls to
'cumulative-grafts', which isn't great performance-wise.
This bug was already present before
d38bc9a9f6.
* guix/grafts.scm (with-cache): In the miss case, call 'current-state'
after EXP has been evaluated.
This fixes a regression introduced in
d38bc9a9f6 whereby the cache was
effectively disabled.
Reported by Thomas Danckaert <thomas.danckaert@gmail.com>.
* guix/grafts.scm (with-cache): In the cache miss case, wrap body in
'mbegin'.
Fixes <http://bugs.gnu.org/24712>.
* guix/grafts.scm (cumulative-grafts): Add grafts for all the outputs of
DRV.
* tests/grafts.scm ("graft-derivation, replaced derivation has multiple
outputs"): New test.
Partly fixes <http://bugs.gnu.org/24418>.
* guix/grafts.scm (cumulative-grafts)[graft-origin?]: New procedure.
[dependency-grafts]: Use it in new 'if' around recursive call.
* tests/grafts.scm ("graft-derivation, grafts are not shadowed"): New test.
Currently, with several grafts applicable to Inkscape, this makes:
guix gc -R $(guix build inkscape -d) | wc -l
go from 2376 to 2266 (4.6%).
* guix/grafts.scm (cumulative-grafts): Pass 'graft-derivation/shallow'
the subset of GRAFTS that applies to DRV.
The time for:
guix build inkscape -n --no-substitutes
goes down by 30% (in the presence of 3 replacements among all the
packages.)
* guix/grafts.scm (cumulative-grafts): Turn into a monadic procedure in
%STATE-MONAD. Use the current state as a derivation-to-graft cache.
(graft-derivation): Call 'cumulative-grafts' within 'run-with-state'.
This avoids starting derivation builds just for the sake of knowing the
references of their outputs, thereby restoring the expected behavior of
--dry-run when substitutes are available.
* guix/grafts.scm (non-self-references): Remove 'store' parameter, and
add 'references'. Use it. Update caller.
(references-oracle): New variable.
(cumulative-grafts): Add 'references' parameter and use it. Update
callers.
(graft-derivation): Remove 'build-derivations' call. Add call to
'references-oracle'.
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.
Before that, outputs of a derivation could be left referring to the
ungrafted version of the derivation.
* guix/grafts.scm (graft-derivation)[outputs]: Change to a list of
name/file pairs.
* guix/grafts.scm (graft-derivation)[build]: Add 'old-outputs' variable
and use it when computing 'mapping'. Use 'mapping' directly.
* tests/grafts.scm ("graft-derivation, multiple outputs"): New test.
