..This simplifies code and mostly ensures we don't print a spinner while there's build activity going on. * build-aux/build-self.scm (build-program): Remove 'spin' and 'call-with-new-thread' call from "compute-guix-derivation" body. Remove "Computing Guix derivation" message. (proxy): Pass extra argument to 'select'. Display a spinner when 'select' returns empty lists. (build): Print "Computing Guix derivation" message here. Ludovic Courtès 2021-04-01build-self: Forward sub-process build output to (current-build-output-port)....Fixes <https://bugs.gnu.org/41930>. * build-aux/build-self.scm (build-program): Add extra 'build-output' parameter. Interpret it as a socket name and connect to it; use it as the CURRENT-BUILD-OUTPUT-PORT. (proxy): New procedure. (build): Open a named socket. Accept connections and call 'proxy' on it. Ludovic Courtès 2021-03-19build-self: Silent Guile warnings while computing the derivation....In particular, silence the Guile-Git autoload warnings introduced by c1940fde43c7aca37d67589cc5cb248086d17d56. * build-aux/build-self.scm (build-program): Wrap 'guix-derivation' call in 'parameterize'. Ludovic Courtès 2021-03-10ci: Remove hydra support....This removes hydra support to use Cuirass as the only continuous integration system. * build-aux/hydra/gnu-system.scm: Remove it. * build-aux/hydra/guix-modular.scm: Ditto. * build-aux/hydra/guix.scm: Ditto. * build-aux/cuirass/hydra-to-cuirass.scm: Ditto. * Makefile.am (EXTRA_DIST): Update it. (hydra-jobs.scm): Remove it. (cuirass-jobs.scm): Update it. * build-aux/hydra/evaluate.scm: Move it to ... * build-aux/cuirass/evaluate.scm: ... here. * build-aux/cuirass/guix-modular.scm: Remove it. * build-aux/cuirass/gnu-system.scm: Ditto. * guix/packages.scm (%hydra-supported-systems): Rename it to ... (%cuirass-supported-systems): ... this variable. * build-aux/check-final-inputs-self-contained: Adapt it. * etc/release-manifest.scm: Ditto. * gnu/ci.scm (package->alist): Remove it. (derivation->job): New procedure. (package-job, package-cross-job, cross-jobs, image-jobs, system-test-jobs, tarball-jobs): Use it. (guix-jobs): New procedure. (hydra-jobs): Rename it to ...
