This patch addresses the last remaining non-reproducible package for core-image-minimal (with current "sumo").
A short explanation: When building core-image-minimal in two different folders with current "sumo" (http://git.yoctoproject.org/cgit/cgit.cgi/poky/log/?h=sumo ) : $ source oe-build-env build_1 local.conf: PACKAGE_CLASSES="package_deb package_rpm package_ipk" MACHINE="qemux86-64" $ bitbake core-image-minimal and $ source oe-build-env build_2 local.conf: PACKAGE_CLASSES="package_deb package_rpm package_ipk" MACHINE="qemux86-64" $ bitbake core-image-minimal After binary comparing all packages in build_1/tmp/deploy/[ipk,rpm.deb] to build_2/tmp/deploy/[ipk,rpm,deb], we get these results: IPK DEB RPM Same: 0 0 0 Different: 3952 3952 3952 Total: 3952 3952 3952 Repeating the same with (same host): $ source oe-build-env build_repro_1 local.conf: PACKAGE_CLASSES="package_deb package_rpm package_ipk" MACHINE="qemux86-64" INHERIT+="reproducible_build" $ bitbake core-image-minimal and $ source oe-build-env build_repro_2 local.conf: PACKAGE_CLASSES="package_deb package_rpm package_ipk" MACHINE="qemux86-64" INHERIT+="reproducible_build" $ bitbake core-image-minimal After binary comparing all packages in build_repro_1/tmp/deploy/[ipk,rpm.deb] to build_repro_2/tmp/deploy/[ipk,rpm,deb], we get these results: IPK DEB RPM Same: 3951 3951 3951 Different: 1 1 1 Total: 3952 3952 3952 The remaining package that does not build reproducibly is python-xcbgen. This is because the package contains .pyc files which contain build-time timestamps. The python files are compiled with host Python3, which may or may not support SOURCE_DATE_EPOCH. However, both oe-core python-native and python3-native do support SOURCE_DATE_EPOCH, so to build the package reproducibly all we need to do is compile the python files with python3-native. Ideally, we would use python3-native unconditionally, but building python3-native itself can be computationally quite expensive. So, as a compromise, we use python3-native only when BUILD_REPRODUCIBLE_BINARIES = '1' host Python3 otherwise.
