From 2718c29c3fb9f9de2ec897248ad49ae11ca39b7a Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Thu, 10 Dec 2020 11:21:14 +0100 Subject: nar: Deduplicate files right as they are restored. This avoids having to traverse and re-read the files that we have just restored, thereby reducing I/O. * guix/serialization.scm (dump-file): New procedure. (restore-file): Add #:dump-file parameter and honor it. * guix/store/deduplication.scm (tee, dump-file/deduplicate): New procedures. * guix/nar.scm (restore-one-item): Pass #:dump-file to 'restore-file'. (finalize-store-file): Pass #:deduplicate? #f to 'register-items'. * tests/nar.scm : Call 'setenv' to set "NIX_STORE". --- tests/nar.scm | 3 +++ 1 file changed, 3 insertions(+) (limited to 'tests/nar.scm') diff --git a/tests/nar.scm b/tests/nar.scm index 59616659c8..ba4881caaa 100644 --- a/tests/nar.scm +++ b/tests/nar.scm @@ -452,6 +452,9 @@ (false-if-exception (rm-rf %test-dir)) (setlocale LC_ALL locale))))) +;; XXX: Tell the 'deduplicate' procedure what store we're actually using. +(setenv "NIX_STORE" (%store-prefix)) + (test-assert "restore-file-set (signed, valid)" (with-store store (let* ((texts (unfold (cut >= <> 10) -- cgit 1.4.1
