2020-12-15	guix system: 'init' copies, resets timestamps, and deduplicates at once.	Ludovic Courtès
	Partly fixes <https://bugs.gnu.org/44760>. * guix/build/store-copy.scm (copy-store-item): New procedure. (populate-store): Use it instead of the inline 'copy-recursively' call. * guix/scripts/system.scm (copy-item): Likewise. Pass #:reset-timestamps? and #:deduplicate? to 'register-path'.
2020-12-15	store-copy: 'populate-store' can optionally deduplicate files.	Ludovic Courtès
	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'.
2020-12-15	store-copy: 'populate-store' resets timestamps.	Ludovic Courtès
	Until now, 'populate-store' would reset permissions but not timestamps, so callers would resort to going through an extra directory traversal to reset timestamps. * guix/build/store-copy.scm (reset-permissions): Remove. (copy-recursively): New procedure. (populate-store): Pass #:keep-permissions? to 'copy-recursively'. Remove call to 'reset-permissions'. * tests/gexp.scm ("gexp->derivation, store copy"): In BUILD-DRV, check whether 'populate-store' canonicalizes permissions and timestamps. * gnu/build/image.scm (initialize-root-partition): Pass #:reset-timestamps? #f to 'register-closure'. * gnu/build/vm.scm (root-partition-initializer): Likewise.
2020-05-05	build: store-copy: Export file-size procedure.	Mathieu Othacehe
	* guix/build/store-copy.scm (file-size): Export it.
2018-11-06	store-copy: Canonicalize the mtime and permissions of the store copy.	Ludovic Courtès
	Fixes a bug whereby directories in the output of 'guix pack -f tarball' would not be read-only. * guix/build/store-copy.scm (reset-permissions): New procedure. (populate-store): Pass #:keep-mtime? #t to 'copy-recursively'. Call 'reset-permissions'. * tests/pack.scm ("self-contained-tarball"): In CHECK, define 'canonical?' and use it to check that every file has an mtime of 1 and is read-only. * tests/guix-pack.sh: Invoke "chmod -Rf +w" before "rm -rf" in trap.
2018-09-23	store-copy: Display a progress bar when copying store items.	Ludovic Courtès
	* guix/build/store-copy.scm (populate-store): Add #:log-port parameter. Use 'progress-reporter/bar' to report progress.
2018-06-14	database: Add 'register-items'.	Ludovic Courtès
	* guix/build/store-copy.scm (store-info): Export. * guix/store/database.scm (register-items): New procedure. (register-path): Implement in terms of 'register-items'. * gnu/build/install.scm (register-closure): Use 'register-items' instead of 'for-each' and 'register-path'.
2018-06-14	store-copy: 'read-reference-graph' returns a list of records.	Ludovic Courtès
	The previous implementation of 'read-reference-graph' was good enough for many use cases, but it discarded the graph structure, which is useful information in some cases. * guix/build/store-copy.scm (<store-info>): New record type. (read-reference-graph): Rewrite to return a list of <store-info>. (closure-size, populate-store): Adjust accordingly. * gnu/services/base.scm (references-file): Adjust accordingly. * gnu/system/vm.scm (system-docker-image): Likewise. * guix/scripts/pack.scm (squashfs-image, docker-image): Likewise. * tests/gexp.scm ("gexp->derivation #:references-graphs"): Likewise.
2017-06-30	vm: Estimate the disk size by default.	Ludovic Courtès
	* gnu/build/vm.scm (estimated-partition-size): New procedure. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Change #:disk-image-size default to 'guess. [builder]: When DISK-IMAGE-SIZE is 'guess, use 'estimated-partition-size' and compute and estimate of the image size. (qemu-image): Likewise. * guix/build/store-copy.scm (file-size, closure-size): New procedures. * guix/scripts/system.scm (%default-options): Change 'image-size' to 'guess. * doc/guix.texi (Building the Installation Image): Remove '--image-size' flag from example. (Invoking guix system): Document the image size estimate.
2014-09-04	vm: Move store copy handling to (guix build store-copy).	Ludovic Courtès
	* gnu/build/vm.scm (read-reference-graph, populate-store): Move to... * guix/build/store-copy.scm: ... here. New file. * Makefile.am (MODULES): Add it. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Adjust default #:modules values accordingly. * tests/gexp.scm ("gexp->derivation, store copy"): New test.
