2018-11-12	store: Add a functional object cache and use it in 'lower-object'.	Ludovic Courtès
	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.

	* guix/build/graft.scm (graft): New procedure. * guix/grafts.scm (graft-derivation/shallow)[build]: Use it instead of inline code.
2017-06-12	derivations: Introduce 'read-derivation-from-file'.	Ludovic Courtès
	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'.
2017-01-25	grafts: Do not pull derivation outputs not depended on.	Ludovic Courtès
	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.
2017-01-24	grafts: Shallow grafting can be performed on a subset of the outputs.	Ludovic Courtès
	* guix/grafts.scm (graft-derivation/shallow): Add #:outputs parameter. [outputs]: Rename to... [output-pairs]: ... this. Adjust 'build-expression->derivation' call accordingly.
2017-01-16	grafts: Preserve the cache across recursive calls.	Ludovic Courtès
	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 d38bc9a9f6feefc465964531520fee5663a12f48. * guix/grafts.scm (with-cache): In the miss case, call 'current-state' after EXP has been evaluated.
2017-01-16	grafts: Actually cache grafts during the derivation DAG traversal.	Ludovic Courtès
	This fixes a regression introduced in d38bc9a9f6feefc465964531520fee5663a12f48 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'.
2017-01-04	grafts: Move caching to a new 'with-cache' macro.	Ludovic Courtès
	* guix/grafts.scm (with-cache): New macro. (cumulative-grafts)[return/cache]: Remove. Use 'with-cache' instead.
2016-10-17	grafts: Apply the right grafts in the presence of multiple outputs.	Ludovic Courtès
	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.
2016-10-15	grafts: Remove unused variables and confusing monad use.	Ludovic Courtès
	* guix/grafts.scm (cumulative-grafts)[return/cache]: Use %STATE-MONAD, not %STORE-MONAD. Remove unused 'origins' variable and unnecessary inner 'cache' variable.
2016-10-14	grafts: 'graft-derivation' does now introduce grafts that shadow other grafts.	Ludovic Courtès
	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.
2016-05-25	grafts: Create only one grafted variant of each derivation.	Ludovic Courtès
	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.
2016-03-14	grafts: Update the narinfo cache before building a derivation.	Ludovic Courtès
	* guix/grafts.scm (references-oracle)[references*]: Add call to 'substitution-oracle'.
2016-03-05	grafts: Memoize intermediate results in 'cumulative-grafts'.	Ludovic Courtès
	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'.
2016-03-05	grafts: Use dependency information from substitutes when possible.	Ludovic Courtès
	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'.
2016-03-01	grafts: Graft recursively.	Ludovic Courtès
	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.
2016-02-27	grafts: Consider all the outputs in the graft mapping.	Ludovic Courtès
	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.
2016-02-27	grafts: Slight simplification.	Ludovic Courtès
	* guix/grafts.scm (graft-derivation)[output-names]: Use 'derivation-output-names'.
2016-02-26	grafts: Add record type printer.	Ludovic Courtès
	* guix/grafts.scm (write-graft): New procedure. Register it as a printer for <graft>.
2016-02-22	grafts: 'name' parameter of 'graft-derivation' is now optional.	Ludovic Courtès
	* guix/grafts.scm (graft-derivation): Name 'name' a keyword parameter. * guix/packages.scm (package-derivation, package-cross-derivation): Adjust accordingly. * tests/grafts.scm ("graft-derivation"): Likewise. * tests/packages.scm ("package-derivation, indirect grafts"): Likewise.
2016-02-22	derivations: Move grafts to (guix grafts).	Ludovic Courtès
	* guix/derivations.scm (<graft>, graft-derivation, %graft?) (set-grafting): Move to... * guix/grafts.scm: ... here. New file. * guix/gexp.scm, guix/packages.scm, tests/packages.scm, guix/scripts/build.scm: Use it. * Makefile.am (MODULES): Add it. (SCM_TESTS): Add tests/grafts.scm. * tests/derivations.scm ("graft-derivation"): Move to... * tests/grafts.scm: ... here. New file.
