From e4752118691e41ae8307649d1abfd4739b3e4bfa Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Fri, 20 Jul 2018 14:49:34 +0200 Subject: database: Reset timestamps to one second after the Epoch. Previously, store items registered in the database by this code (for instance, store items retrieved by 'guix offload' and passed to 'restore-file-set') would have an mtime of 0 instead of 1. This would cause problems for things like .go files: Guile would consider them to be older than the corresponding .scm file, and consequently it would ignore them and possibly use another (incorrect) .go file. Reported by Ricardo Wurmus. * guix/store/database.scm (reset-timestamps): Pass 1, not 0, to 'utime'. * tests/store-database.scm ("register-path"): Check the mtime of FILE and REF. --- guix/store/database.scm | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'guix') diff --git a/guix/store/database.scm b/guix/store/database.scm index 8f35b63e37..0879a95d0b 100644 --- a/guix/store/database.scm +++ b/guix/store/database.scm @@ -190,12 +190,14 @@ Every store item in REFERENCES must already be registered."
