From 8f417ed28061c11c7ff2649cfa15e35b00ef9a0b Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Sun, 13 Oct 2019 23:12:44 +0200 Subject: gnu: commencement: Further optimize the package object graph. For a package like: (define-public xxx (package (inherit (@ (gnu packages base) coreutils)) (name "xxx") (inputs (@ (gnu packages commencement) %final-inputs)) (native-inputs '()) (propagated-inputs '()) (arguments '(#:implicit-inputs? #f)))) this reduces the package object graph from 176 nodes (1852 edges) to 113 nodes (1114 edges). The number of 'add-data-to-store' calls in "guix build coreutils -nd" drops from 2045 to 1301, and the number of memoization tables drops from 102 to 40. "guix build libreoffice -nd" goes from 2.40s to 2.27s. * gnu/packages/commencement.scm (with-boot4): New variable. (guile-final, glibc-utf8-locales-final): Use it. (with-boot4, with-boot5): New variable. (gnu-make-final): Rewrite to avoid 'package-with-explicit-inputs'. (coreutils-final): Use 'with-boot5' instead of 'package-with-explicit-inputs'. (grep-final): Likewise. (with-boot6): New variable. (sed-final, %final-inputs): Use it. --- gnu/packages/commencement.scm | 74 +++++++++++++++++++++++-------------------- 1 file changed, 40 insertions(+), 34 deletions(-) (limited to 'gnu/packages/commencement.scm') diff --git a/gnu/packages/commencement.scm b/gnu/packages/commencement.scm index d113acaba8..fd976e0c2f 100644 --- a/gnu/packages/commencement.scm +++ b/gnu/packages/commencement.scm @@ -2365,14 +2365,14 @@ exec ~a/bin/~a-~a -B~a/lib -Wl,-dynamic-linker -Wl,~a/~a \"$@\"~%" `(("bash" ,bash-final) ,@(alist-delete "bash" (%boot3-inputs)))) +(define with-boot4 + (package-with-explicit-inputs %boot4-inputs %bootstrap-guile)) + (define-public guile-final ;; This package must be public because other modules refer to it.
