From e7c5eb54af669f2b95d760646e526f2d8728be66 Mon Sep 17 00:00:00 2001 From: "Bernhard M. Wiedemann" Date: Tue, 1 Apr 2025 18:52:50 +0200 Subject: [PATCH] Use RELEASE_NOTES date instead of build date Use `RELEASE_NOTES` date instead of build date 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. This date call only works with GNU date and BSD date. Alternatively, https://reproducible-builds.org/docs/source-date-epoch/#makefile could be implemented. This patch was done while working on reproducible builds for openSUSE, sponsored by the NLnet NGI0 fund. --- Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/Makefile b/Makefile index bfdf2ff9..dcd9cebd 100644 --- a/Makefile +++ b/Makefile @@ -24,7 +24,7 @@ else DEB_PACKAGE_NAME := $(BINARY_NAME) endif -DATE := $(shell date -u '+%Y-%m-%d-%H%M UTC') +DATE := $(shell date -u -r RELEASE_NOTES '+%Y-%m-%d-%H%M UTC') VERSION_FLAGS := -X "main.Version=$(VERSION)" -X "main.BuildTime=$(DATE)" ifdef PACKAGE_MANAGER VERSION_FLAGS := $(VERSION_FLAGS) -X "github.com/cloudflare/cloudflared/cmd/cloudflared/updater.BuiltForPackageManager=$(PACKAGE_MANAGER)"
