2017-01-11perform-download: Add backward-compatible case....This is meant to ease transition for people running an older guix-daemon invoking a recent 'guix perform-download' with only one argument. This is a followup to 9b5364a3afb03414bd6e3ded2fbfdacabe4e8870. * guix/scripts/perform-download.scm (perform-download): Make 'output' optional. Bind 'output*' from DRV's "out" and honor it. (guix-perform-download): Add clause with one argument. Ludovic Courtès
2017-01-11daemon: Allow check builds of 'builtin:download' derivations....Fixes <http://bugs.gnu.org/25089>. Reported by Leo Famulari <leo@famulari.name>. * nix/libstore/build.cc (DerivationGoal::runChild): In the 'isBuiltin' case, check whether DRV's output is in 'redirectedOutputs', and pass an 'output' argument to the built-in builder. (DerivationGoal::addHashRewrite): Add 'printMsg' call. * nix/libstore/builtins.hh (derivationBuilder): Add 'output' parameter. * nix/libstore/builtins.cc (builtinDownload): Likewise. Add OUTPUT to ARGV. * guix/scripts/perform-download.scm (perform-download): Add 'output' parameter. (guix-perform-download): Adjust 'match' clauses accordingly. * tests/derivations.scm ("'download' built-in builder, check mode"): New test. Ludovic Courtès
2016-11-16daemon: Add "builtin:download" derivation builder....This ensures that 1) the derivation doesn't change when Guix changes; 2) the derivation closure doesn't contain Guix and its dependencies; 3) we don't have to rely on ugly chroot hacks. Adapted from Nix commit 0a2bee307b20411f5b0dda0c662b1f9bb9e0e131. * nix/libstore/build.cc (DerivationGoal::runChild): Add special case for 'isBuiltin(drv)'. Disable chroot when 'isBuiltin(drv)'. * nix/libstore/builtins.cc, nix/libstore/builtins.hh, nix/scripts/download.in, guix/scripts/perform-download.scm: New files. * guix/ui.scm (show-guix-help)[internal?]: Add 'perform-download'. * nix/local.mk (libstore_a_SOURCES): Add builtins.cc. (libstore_headers): Add builtins.hh. (nodist_pkglibexec_SCRIPTS): Add 'scripts/download'. * config-daemon.ac: Emit 'scripts/download'. * Makefile.am (MODULES): Add 'guix/scripts/perform-download.scm'. * tests/derivations.scm ("unknown built-in builder") ("'download' built-in builder") ("'download' built-in builder, invalid hash") ("'download' built-in builder, not found") ("'download' built-in builder, not fixed-output"): New tests.
