grafts: 'references-oracle' now takes a derivation input.

2019-07-02T16:33:51Z

That way, if we end up calling 'build-derivations', we'll only build the outputs that we really need. * guix/grafts.scm (references-oracle): Rename 'drv' to 'input'. [output-paths]: Remove. Adjust accordingly. (graft-derivation): Adjust call to 'references-oracle'.

grafts: Avoid 'query-valid-derivers' RPC.

2019-06-19T20:56:27Z

Previously we'd make 502 'query-valid-derivers' RPCs for "guix build vim -d", and after this patch, we don't do any. Furthermore, the previous strategy was "stateful" in the sense that 'item->deriver' could return a derivation that is not the one that was actually computed by this process, but an "equivalent" one (due to fixed-output derivations); which one is chosen would depend on the state of the store. This in turn means that we'd have to call 'read-derivation-from-file' to actually read .drv files (as opposed to getting them from %DERIVATION-CACHE). This is costly and doesn't work with GUIX_DAEMON_SOCKET=ssh://…. * guix/grafts.scm (item->deriver): Remove. (reference-origin): New procedure. (cumulative-grafts): Use it instead of 'item->deriver'.

store: Rename '&nix-error' to '&store-error'.

2019-01-21T22:09:55Z

* guix/store.scm (&nix-error): Rename to... (&store-error): ... this, and adjust users. (&nix-connection-error): Rename to... (&store-connection-error): ... this, and adjust users. (&nix-protocol-error): Rename to... (&store-protocol-error): ... this, adjust users. (&nix-error, &nix-connection-error, &nix-protocol-error): Define these condition types and their getters as deprecrated aliases. * build-aux/run-system-tests.scm, guix/derivations.scm, guix/grafts.scm, guix/scripts/challenge.scm, guix/scripts/graph.scm, guix/scripts/lint.scm, guix/scripts/offload.scm, guix/serialization.scm, guix/ssh.scm, guix/tests.scm, guix/ui.scm, tests/derivations.scm, tests/gexp.scm, tests/guix-daemon.sh, tests/packages.scm, tests/store.scm, doc/guix.texi: Adjust to use the new names.

grafts: Mark as non substitutable.

2018-12-04T09:57:56Z

* guix/grafts.scm (graft-derivation/shallow): Pass #:substitutable? to 'build-expression->derivation'.

grafts: Record metadata as derivation properties.

2018-11-28T09:39:58Z

* 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'.

store: Add a functional object cache and use it in 'lower-object'.

2018-11-12T22:37:13Z

This leads to ~25% improvements on things like: guix system build desktop.tmpl --no-grafts -d * guix/store.scm ()[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.

grafts: Add (guix build debug-link) and use it.

2018-08-24T16:01:05Z

Fixes . Reported by Mark H Weaver . * 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.

grafts: Add high-level 'graft' procedure on the build side.

2018-08-24T15:57:56Z

* guix/build/graft.scm (graft): New procedure. * guix/grafts.scm (graft-derivation/shallow)[build]: Use it instead of inline code.

derivations: Introduce 'read-derivation-from-file'.

2017-06-12T15:53:51Z

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'.

grafts: Do not pull derivation outputs not depended on.

2017-01-25T10:04:25Z

Fixes . 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.
