It seems that with Rawhide rpm, not found patches do not terminate the build, they just print out an error. With the "Patch0: not applied with %patch and Patch: not applied with %patch0" change in the new rpm, this will cause quite a few regressions and possibly security issues unless people happen to read their build logs carefully - essentially some patches just do not get applied. One example here: http://kojipkgs.fedoraproject.org/packages/mboxgrep/0.7.9/6.fc10/data/logs/x86_64/build.log [...] Executing command: ['bash', '--login', '-c', 'rpmbuild -bb --target x86_64 --nodeps builddir/build/SPECS/mboxgrep.spec'] /etc/profile: line 38: /bin/hostname: No such file or directory error: %patch without corresponding "Patch:" tag Building target platforms: x86_64 Building for target x86_64 Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.Kbstjz [...] An error is printed, but the build continues without the patch applied. The build should IMO be terminated instead. I don't have a Rawhide box to test with, but can reproduce locally in mock on a F-9 system. I hacked my mock to not use --nodeps with rpmbuild -bb just to try it out, but it had no effect on this issue. There are about 60 packages in Rawhide that are potentially affected, will post to fedora-devel about it soon.
Fixed in upstream and rawhide. Thanks for noticing.
