From 6a060ff27ff68384d7c90076baa36c349fff689d Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Thu, 10 Dec 2020 15:12:34 +0100 Subject: store-copy: 'populate-store' can optionally deduplicate files. Until now deduplication was performed as an additional pass after copying files, which involve re-traversing all the files that had just been copied. * guix/store/deduplication.scm (copy-file/deduplicate): New procedure. * tests/store-deduplication.scm ("copy-file/deduplicate"): New test. * guix/build/store-copy.scm (populate-store): Add #:deduplicate? parameter and honor it. * tests/gexp.scm ("gexp->derivation, store copy"): Pass #:deduplicate? #f to 'populate-store'. * gnu/build/image.scm (initialize-root-partition): Pass #:deduplicate? to 'populate-store'. Pass #:deduplicate? #f to 'register-closure'. * gnu/build/vm.scm (root-partition-initializer): Likewise. * gnu/build/install.scm (populate-single-profile-directory): Pass #:deduplicate? #f to 'populate-store'. * gnu/build/linux-initrd.scm (build-initrd): Likewise. * guix/scripts/pack.scm (self-contained-tarball)[import-module?]: New procedure. [build]: Pass it as an argument to 'source-module-closure'. * guix/scripts/pack.scm (squashfs-image)[build]: Wrap in 'with-extensions'. * gnu/system/linux-initrd.scm (expression->initrd)[import-module?]: New procedure. [builder]: Pass it to 'source-module-closure'. * gnu/system/install.scm (cow-store-service-type)[import-module?]: New procedure. Pass it to 'source-module-closure'. --- gnu/system/install.scm | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) (limited to 'gnu/system/install.scm') diff --git a/gnu/system/install.scm b/gnu/system/install.scm index a6b9e3d952..e753463473 100644 --- a/gnu/system/install.scm +++ b/gnu/system/install.scm @@ -1,5 +1,5 @@ ;;; GNU Guix --- Functional package management for GNU -;;; Copyright © 2014, 2015, 2016, 2017, 2018, 2019 Ludovic Courtès +;;; Copyright © 2014, 2015, 2016, 2017, 2018, 2019, 2020 Ludovic Courtès ;;; Copyright © 2015 Mark H Weaver ;;; Copyright © 2016 Andreas Enge ;;; Copyright © 2017 Marius Bakke @@ -176,6 +176,13 @@ (define cow-store-service-type (shepherd-service-type 'cow-store (lambda _ + (define (import-module? module) + ;; Since we don't use deduplication support in 'populate-store', don't + ;; import (guix store deduplication) and its dependencies, which + ;; includes Guile-Gcrypt. + (and (guix-module-name? module) + (not (equal? module '(guix store deduplication))))) + (shepherd-service (requirement '(root-file-system user-processes)) (provision '(cow-store)) @@ -190,7 +197,8 @@ (define cow-store-service-type ,@%default-modules)) (start (with-imported-modules (source-module-closure - '((gnu build install))) + '((gnu build install)) + #:select? import-module?) #~(case-lambda ((target) (mount-cow-store target #$%backing-directory) -- cgit v1.2.3
