From 45779fa676419de8838cb26b6c7a24678a2be1cd Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Mon, 18 Jun 2018 22:43:44 +0200 Subject: self: Make (guix config) generation really stateless. Previously the %CONFIG-VARIABLES list would be generated based on what the current (guix config) contains. Thus, it would include '%guix-register-program', which we recently removed, because existing (guix config) most likely contained that variable. Since its value could differ from machine to machine, the build farm could be building a different config.scm, thereby preventing people from getting substitutes. * guix/self.scm (%config-variables): Turn into a white list instead of taking all the remaining variables from the current (guix config). * build-aux/build-self.scm (%config-variables): Likewise. --- build-aux/build-self.scm | 21 ++++++++++----------- guix/self.scm | 24 +++++++++++------------- 2 files changed, 21 insertions(+), 24 deletions(-) diff --git a/build-aux/build-self.scm b/build-aux/build-self.scm index 5898b6515c..4de91f7fff 100644 --- a/build-aux/build-self.scm +++ b/build-aux/build-self.scm @@ -63,17 +63,16 @@ %guix-home-page-url)) (define %config-variables - ;; (guix config) variables corresponding to Guix configuration (storedir, - ;; localstatedir, etc.) - (sort (filter pair? - (module-map (lambda (name var) - (and (not (memq name %dependency-variables)) - (not (memq name %persona-variables)) - (cons name (variable-ref var)))) - (resolve-interface '(guix config)))) - (lambda (name+value1 name+value2) - (stringstring (car name+value1)) - (symbol->string (car name+value2)))))) + ;; (guix config) variables corresponding to Guix configuration. + (letrec-syntax ((variables (syntax-rules () + ((_) + '()) + ((_ variable rest ...) + (cons `(variable . ,variable) + (variables rest ...)))))) + (variables %config-directory %localstatedir %state-directory + %store-database-directory %store-directory + %storedir %sysconfdir %system))) (define* (make-config.scm #:key libgcrypt zlib gzip xz bzip2 (package-name "GNU Guix") diff --git a/guix/self.scm b/guix/self.scm index 5a10f72012..cce418df41 100644 --- a/guix/self.scm +++ b/guix/self.scm @@ -26,9 +26,8 @@ #:use-module (guix discovery) #:use-module (guix packages) #:use-module (guix sets) - #:use-module (guix utils) #:use-module (guix modules) - #:use-module (guix build utils) + #:use-module ((guix build utils) #:select (find-files)) #:use-module ((guix build compile) #:select (%lightweight-optimizations)) #:use-module (srfi srfi-1) #:use-module (srfi srfi-9) @@ -666,17 +665,16 @@ assumed to be part of MODULES." %guix-home-page-url)) (define %config-variables - ;; (guix config) variables corresponding to Guix configuration (storedir, - ;; localstatedir, etc.) - (sort (filter pair? - (module-map (lambda (name var) - (and (not (memq name %dependency-variables)) - (not (memq name %persona-variables)) - (cons name (variable-ref var)))) - (resolve-interface '(guix config)))) - (lambda (name+value1 name+value2) - (stringstring (car name+value1)) - (symbol->string (car name+value2)))))) + ;; (guix config) variables corresponding to Guix configuration. + (letrec-syntax ((variables (syntax-rules () + ((_) + '()) + ((_ variable rest ...) + (cons `(variable . ,variable) + (variables rest ...)))))) + (variables %config-directory %localstatedir %state-directory + %store-database-directory %store-directory + %storedir %sysconfdir %system))) (define* (make-config.scm #:key libgcrypt zlib gzip xz bzip2 (package-name "GNU Guix") -- cgit v1.2.3
