Before it would list inputs not built, even if the outputs of the given
derivation were already available.
* guix/derivations.scm (derivation-prerequisites-to-build): Add
`outputs' keyword parameter.
[built?, derivation-built?]: New procedures.
[loop]: Add `sub-drvs' parameter. Use `derivation-built?' to check if
the SUB-DRVS of DRV are built before checking its inputs.
* tests/builders.scm (network-reachable?): New variable.
("url-fetch", "gnu-build"): Skip unless NETWORK-REACHABLE?.
* tests/derivations.scm (%coreutils): Check for network access.
("build-expression->derivation with one input"): Skip when %COREUTILS
is #f.
* tests/guix-package.sh: Skip installation of GNU Make when the network
is unreachable.
* tests/packages.scm ("GNU Make, bootstrap"): Likewise.
* tests/union.scm ("union-build"): Likewise.
* guix/derivations.scm (derivation)[inputs]: Fix typo in call to
`add-to-store'.

* tests/packages.scm ("trivial with local file as input"): New test.
* tests/derivations.scm ("build-expression->derivation for fixed-output
derivation"): Remove test. It is redundant with that in builders.scm,
and doesn't work out of the box with the statically-linked
%BOOTSTRAP-GUILE.
* guix/derivations.scm (build-expression->derivation)[source-path]: New
procedure.
[builder]: Pass only sources as references. This fixes a bug whereby
changing a fixed-output drv referred to by a builder would cause the
builder's hash to change, thereby leading to a full rebuild.
* tests/derivations.scm ("build-expression->derivation with a
fixed-output input"): New test.
* tests/derivations.scm ("fixed-output derivation"): Add comment that
the reference to BUILDER is optional.
("fixed-output derivation: output paths are equal",
"derivation with a fixed-output input",
"build-expression->derivation: same fixed-output path"): New tests.
* tests/builders.scm (%bootstrap-inputs): Use %BOOT0-INPUTS from the distro.
* tests/packages.scm (%bootstrap-inputs): Likewise.
* tests/derivations.scm (%coreutils): Alias for %BOOTSTRAP-COREUTILS&CO.
* guix/derivations.scm (%guile-for-build): Initialize to #f.
(imported-files, imported-modules, compiled-modules): Add `guile'
keyword parameter. Pass it down to `build-expression->derivation'.
(build-expression->derivation)[guile-drv]: New variable. Pass it as
the #:guile parameter for `imported-modules' and `compiled-modules'.
* tests/derivations.scm: Set %GUILE-FOR-BUILD to the derivation of
%BOOTSTRAP-GUILE.
* guix/derivations.scm (imported-files)[parent-dirs]: Move to...
(parent-directories): ... here. New procedure.
(compiled-modules): New procedure.
(build-expression->derivation): Use it.
* tests/derivations.scm ("build-expression->derivation with modules"):
New test.
* guix/derivations.scm (write-derivation)[coalesce-duplicate-inputs]:
New procedure.
Use it to process INPUTS.
* tests/derivations.scm ("user of multiple-output derivation"): New
test.
* guix/derivations.scm (derivation-prerequisites,
derivation-prerequisites-to-build): New procedures.
* tests/derivations.scm ("build-expression->derivation and
derivation-prerequisites", "build-expression->derivation and
derivation-prerequisites-to-build"): New tests.
* guix/store.scm (valid-path?): New procedure.
* tests/builders.scm ("http-fetch", "gnu-build"): Use it.
* tests/derivations.scm ("add-to-store, flat", "add-to-store,
recursive", "derivation with no inputs", "build derivation with 1
source", "build derivation with coreutils",
"build-expression->derivation with expression returning #f"):
Likewise.
* guix/derivations.scm (build-expression->derivation)[builder]: Pass the
result of EXP to `exit'.
* tests/derivations.scm ("build-expression->derivation with expression
returning #f"): New test.
* guix/derivations.scm (build-expression->derivation): Change to expect
INPUTS to have the form (NAME DRV-PATH SUB-DRV) or (NAME DRV-PATH),
instead of (NAME . DRV-PATH). Update callers accordingly.
* guix/gnu-build-system.scm, tests/builders.scm, tests/derivations.scm:
Update accordingly.
* guix/derivations.scm (imported-files)[builder]: For TAIL, check
whether it exists before (mkdir TAIL).
* tests/derivations.scm ("imported-files"): Add file with a common
prefix.
* guix/derivations.scm (imported-files): New procedure.
(build-expression->derivation): Correctly handle inputs that are
sources and not derivation paths.
* tests/derivations.scm ("imported-files"): New test.
* guix/utils.scm (gnu-triplet->nix-system): New procedure.
(%current-system): New variable.
* tests/utils.scm ("gnu-triplet->nix-system"): New test.
* tests/derivations.scm (%current-system): Remove. Update users to
use (%current-system) instead.
* guix/derivations.scm (build-expression->derivation): Add `outputs'
keyword parameter; pass it to `derivation'. Define `%outputs' in the
prologue.
* tests/derivations.scm ("build-expression->derivation with two
outputs"): New test.
* guix/derivations.scm (build-expression->derivation): Pass HASH and
HASH-ALGO to `derivation'.
* tests/derivations.scm ("build-expression->derivation for fixed-output
derivation"): New test.
* guix/derivations.scm (read-derivation)[outputs->alist]: For
fixed-outputs, convert HASH with `base16-string->bytevector'.
(write-derivation): Likewise, convert HASH-ALGO to a string and HASH
to a base16 string.
(derivation-hash): Expect HASH to be a bytevector, not a string;
convert HASH with `bytevector->base16-string'.
* tests/derivations.scm ("fixed-output derivation"): New test.
* guix/derivations.scm (%guile-for-build): New parameter.
(build-expression->derivation): New procedure.
* tests/derivations.scm ("build-expression->derivation without inputs",
"build-expression->derivation with one input"): New tests.
* guix/derivations.scm (derivation-path->output-path): New procedure.
(derivation-hash): Call `memoize'. In the fixed-output case, convert
HASH-ALGO to a string. In the other case, sort inputs in the
alphabetical order of their hex hash. For inputs with no sub-drvs,
add "out" as the sub-drv.
* guix/utils.scm (%nixpkgs-directory): New parameter.
(nixpkgs-derivation, memoize): New procedures.
* tests/derivations.scm ("build derivation with 1 source"): Remove
useless shebang.
