File reproducible.patch of Package libgda
merged upstream: https://gitlab.gnome.org/GNOME/libgda/-/merge_requests/192 From c9837a3438622d49fe6a727d2512e0f0bb3827d7 Mon Sep 17 00:00:00 2001 From: "Bernhard M. Wiedemann" <bwiedemann@suse.de> Date: Wed, 2 Feb 2022 14:25:57 +0100 Subject: [PATCH] Allow to override build date with SOURCE_DATE_EPOCH in order to make builds reproducible. See https://reproducible-builds.org/ for why this is good and https://reproducible-builds.org/specs/source-date-epoch/ for the definition of this variable. Also use UTC to be independent of timezone. --- meson.build | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/meson.build b/meson.build index 62b465941..bc4cecace 100644 --- a/meson.build +++ b/meson.build @@ -321,10 +321,18 @@ found_jdbc = false dates = compiler.run(''' #include<glib.h> #include <glib/gprintf.h> +#include <stdlib.h> void main (void) { GDateTime *dt; - dt = g_date_time_new_now_local (); + char *source_date_epoch; + gint64 epoch; + /* This assumes that the SOURCE_DATE_EPOCH environment variable will contain + a correct, positive integer */ + if ((source_date_epoch = getenv("SOURCE_DATE_EPOCH")) == NULL || + (epoch = (time_t)strtoll(source_date_epoch, NULL, 10)) <= 0 || + (dt = g_date_time_new_from_unix_utc(epoch)) == NULL) + dt = g_date_time_new_now_utc (); g_print (g_date_time_format(dt, "%F")); } ''', -- GitLab
