Ludovic Courtès 8bd4126917 substitute: Retry downloading when a nar is unavailable. ... Fixes <https://issues.guix.gnu.org/57978> Reported by Attila Lendvai <attila@lendvai.name>. Previously, if a narinfo was available but its corresponding nar was missing (for instance because the narinfo was cached and the server became unreachable in the meantime), 'guix substitute --substitute' would try to download the nar from its preferred location and abort when that fails. This change forces one retry with each of the URLs. * guix/scripts/substitute.scm (download-nar): Do not catch 'http-get-error?' exceptions. (system-error?, network-error?, process-substitution/fallback): New procedures. (process-substitution): Call 'process-substitution/fallback' upon 'network-error?'. * tests/substitute.scm ("substitute, first URL has narinfo but lacks nar, second URL unauthorized") ("substitute, first URL has narinfo but nar is 404, both URLs authorized") ("substitute, first URL has narinfo but nar is 404, one URL authorized") ("substitute, narinfo is available but nar is missing"): New tests.		2022-09-28 22:28:27 +02:00
