[opensuse-buildservice] how to get the date of last package change
Hi. From within spec file I want to get the date when the package was edited last time. Unfortunately obs repos do not seem to save the correct timestamps of source files. The only way I could imagine right now is to take the timestamp of the last "*.changes" entry. Is there a better way? cu, Rudi -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

This is in fact the advertised way if you absolutely need the "current" time. (For example, if you intend to replace -TIME__/__DATE__. Though, in case of __DATE__/__TIME__, I just define them to the empty string, which is a lot quicker.) -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

I'd like to have a reasonable build date in --version output as supposed by upstream. I find it funny that OBS does not support such feature ... But no problem I'm going to parse the .changes file like this: %build # export deterministic BUILD_DATE, format like "__DATE__ __TIME__" CL_DATE="$(awk -F " - " 'NR==2{print $1;}' %{_sourcedir}/%{name}.changes)" test -n "$CL_DATE" export BUILD_DATE="$(LANG=C date --utc -d "${CL_DATE}" +"%b %e %Y %T")" cu, Rudi -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

Providing of build date causes unreproducible builds that increases service load so the latest changes date is much better. -- Best regards, Dmitriy DA(P).DarkneSS Perlow @ Linux x64 -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org

Make sure to add the .changes file to the Source: list when you access it during build (and reference it by %{sourceN} Otherwise the resulting .src.rpm is useless. Dominique -- Dimstar / Dominique Leuenberger <dimstar@opensuse.org>
