FYI, Fedora reviewed vdsm spec file regarding obsoletes. ---------- Forwarded message ---------- From: Igor Gnatenko <ignatenko(a)redhat.com&gt; Date: Fri, Sep 2, 2016 at 1:14 PM Subject: Unversioned and >/=/>= obsoletes To: Development discussions related to Fedora <devel(a)lists.fedoraproject.org&gt;, devel-announce(a)lists.fedoraproject.org All guidelines mandate the use of </<= Obsoletes, but unfortunately we have some number of packages (179 source rpms -> 292 binary rpms) with unversioned Obsoletes or with >/=/>= Obsoletes. It is causing problems with upgrade (if package is getting re-added) or with 3rd-party repositories. Older package is obsoleting new package. Problem categories (in following text by "never" I mean latest N-2 releases): * Package/SubPackage was never built in Fedora Package "python" has "Obsoletes: python2" which was never built -> drop Obsoletes SubPackage "qpid-proton-c" of "qpid-proton" has "Obsoletes: qpid-proton" which was not the package for long time -> drop Obsoletes * Package replacement Package "storaged" has "Obsoletes: udisks2" -> take latest version from koji (2.1.7-1) and make Obsoletes versioned: udisks2 < 2.1.7-2 storaged is not simple use-case as it replaces udisks2, but latter is still not retired. * "=" Obsoletes "rubygem-vte" has "Obsoletes: ruby-vte = 3.0.9-1.fc26" (probably it's macro in spec) which seems really weird as it will not obsolete F24/F25 with such version * Obsoletes by Provides It doesn't work to prevent undefined behavior. Imagine you have installed "A" and "B", both providing "C". Package "D" has "Obsoletes: C", it should not remove "A" and "B". ** %{?_isa} "glibc-headers" has "Obsoletes: glibc-headers(i686)". %{?_isa} is just text, it's not part of architecture or something else. ** Other provides "rubygem-http_connection" has "Obsoletes: rubygem(right_http_connection)". Latter is virtual provides. * Weird obsoletes (broken) "krb5-server" has "Obsoletes: krb5-server-1.14.3-8.fc26.i686". Basically it will not obsolete anything because it's threated as package name (and we definitely don't have such package name). * >/>= Obsoletes "vdsm" has "Obsoletes: vdsm-infra >= 4.16.0". It's almost same as unversioned Obsoletes. So it must not be used.
