Yet another try: Are you saying this is not true? ... From https://pagure.io/Fedora-Infra/rpmautospec/tree/master: "- Attempt to automatically calculate release numbers and generate an RPM changelog from the dist-git repository of a package and the information available in the Koji build system." and lines like this: https://pagure.io/Fedora-Infra/rpmautospec/blob/3c208f17329940977cbe1552f3d1bbee35014f93/f/rpmautospec/tag_package.py#_53 are not needed? From what I see, you clearly _are_ using build system to generate release information. The fact that you are doing it through some tagging middle step is completely irrelevant cause it is just a middle step. > > > Pierre > _______________________________________________ > devel mailing list -- devel@lists.fedoraproject.org > To unsubscribe send an email to devel-le...@lists.fedoraproject.org > Fedora Code of Conduct: > https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: > https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
