From ba04f80e2e0fd92ca381c8fac8a659cb8f9abdd2 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Wed, 19 Jun 2019 22:05:06 +0200 Subject: derivations: Rewrite and replace 'derivations-prerequisites-to-build'. The new 'derivation-build-plan' procedure has a more appropriate signature: it takes a list of instead of taking one . Its body is also much simpler. * guix/derivations.scm (derivation-build-plan): New procedure. (derivation-prerequisites-to-build): Express in terms of 'derivation-build-plan' and mark as deprecated. * tests/derivations.scm: Change 'derivation-prerequisites-to-build' tests to 'derivation-build-plan' and adjust accordingly. --- tests/derivations.scm | 63 ++++++++++++++++++++++++++++----------------------- 1 file changed, 35 insertions(+), 28 deletions(-) (limited to 'tests') diff --git a/tests/derivations.scm b/tests/derivations.scm index 93f4cdd8ee..35fb20bab0 100644 --- a/tests/derivations.scm +++ b/tests/derivations.scm @@ -809,13 +809,13 @@ (equal?
