From 2ea2aac6e9d58a07c029504f94fb5015cd407e31 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Tue, 18 Apr 2017 22:07:49 +0200 Subject: Add (guix cache) and use it in (guix scripts substitute). * guix/cache.scm, tests/cache.scm: New files. * Makefile.am (MODULES, SCM_TESTS): Add them. * guix/scripts/substitute.scm (obsolete?): Remove. (remove-expired-cached-narinfos): Rename to... (cached-narinfo-expiration-time): ... this. Remove the removal part and only keep the expiration time part. (narinfo-cache-directories): Add optional 'directory' parameter and honor it. (maybe-remove-expired-cached-narinfo): Remove. (cached-narinfo-files): New procedure. (guix-substitute): Use 'maybe-remove-expired-cache-entries' instead of 'maybe-remove-expired-cached-narinfo'. --- tests/cache.scm | 81 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 81 insertions(+) create mode 100644 tests/cache.scm (limited to 'tests/cache.scm') diff --git a/tests/cache.scm b/tests/cache.scm new file mode 100644 index 0000000000..0e1e08b693 --- /dev/null +++ b/tests/cache.scm @@ -0,0 +1,81 @@ +;;; GNU Guix --- Functional package management for GNU +;;; Copyright © 2017 Ludovic Courtès +;;; +;;; This file is part of GNU Guix. +;;; +;;; GNU Guix is free software; you can redistribute it and/or modify it +;;; under the terms of the GNU General Public License as published by +;;; the Free Software Foundation; either version 3 of the License, or (at +;;; your option) any later version. +;;; +;;; GNU Guix is distributed in the hope that it will be useful, but +;;; WITHOUT ANY WARRANTY; without even the implied warranty of +;;; MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
