From 7a61549b6313d31c5a97fff46367cd5188804f92 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C3=A9r=C3=A9my=20Bobbio?= <[email protected]> Date: Fri, 29 Aug 2014 03:46:09 +0000 Subject: [PATCH] dh_fixmtimes: introduce new helper to fix mtimes for reproducibility To enable reproducible builds, file modification times written in binary packages should be the same accross multiple builds of the same source package. This helper will change the modification time of any file that has been created later than the time of the latest debian/changelog entry to the time of the latest debian/changelog entry. See https://wiki.debian.org/ReproducibleBuilds for more information on reproducible builds in Debian. --- Debian/Debhelper/Dh_Lib.pm | 4 ++- dh | 1 + dh_fixmtimes | 76 ++++++++++++++++++++++++++++++++++++++++++++ man/po4a/po4a.cfg | 1 + 4 files changed, 81 insertions(+), 1 deletion(-) create mode 100755 dh_fixmtimes diff --git a/Debian/Debhelper/Dh_Lib.pm b/Debian/Debhelper/Dh_Lib.pm index 6a79c9c..44c3ced 100644 --- a/Debian/Debhelper/Dh_Lib.pm +++ b/Debian/Debhelper/Dh_Lib.pm @@ -477,7 +477,8 @@ sub pkgfilename { } # Returns 1 if the package is a native debian package, null otherwise. -# As a side effect, sets $dh{VERSION} to the version of this package. +# As a side effect, sets $dh{VERSION} to the version of this package, +# and $dh{DATE} to the date of the latest changelog entry. { # Caches return code so it only needs to run dpkg-parsechangelog once. my %isnative_cache; @@ -499,6 +500,7 @@ sub pkgfilename { if (! defined $dh{VERSION}) { error("changelog parse failure"); } + ($dh{DATE})=$version=~m/Date:\s*(.*)/m; # Is this a native Debian package? if ($dh{VERSION}=~m/.*-/) { diff --git a/dh b/dh index f3bd321..fc300b8 100755 --- a/dh +++ b/dh @@ -408,6 +408,7 @@ my @b=qw{ dh_installdeb dh_gencontrol dh_md5sums + dh_fixmtimes dh_builddeb }; $sequences{clean} = [qw{ diff --git a/dh_fixmtimes b/dh_fixmtimes new file mode 100755 index 0000000..28122c7 --- /dev/null +++ b/dh_fixmtimes @@ -0,0 +1,76 @@ +#!/usr/bin/perl -w + +=encoding utf-8 + +=head1 NAME + +dh_fixperms - fix mtimes of files in package build directories + +=cut + +use strict; +use Config; +use Debian::Debhelper::Dh_Lib; + +=head1 SYNOPSIS + +B<dh_fixmtimes> [S<I<debhelper options>>] [B<-X>I<item>] + +=head1 DESCRIPTION + +B<dh_fixmtimes> is a debhelper program that is responsible for setting the +modification times of files and directories in package build directories to +a state easily reproducible accross multiple builds. + +B<dh_fixperms> will examine the modification time of all files in the package +build directory.
