Description Daniel Berrangé 2012-01-09 17:12:51 UTC

Description of problem:
Attempting to build the latest perl-Sys-Virt RPM, I encountered an unresolvable
dependency in Systemtap on PPC architectures:

http://download.devel.redhat.com/brewroot/work/tasks/7361/3927361/root.log

DEBUG util.py:256:  Error: Missing Dependency: kernel-devel is needed by
package systemtap-1.6-4.el6.ppc (build)


The problem is that 'kernel-devel' is not built on PPC architecture in RHEL-6.
So AFAICT, there is no way that the 'systemtap' RPM can ever be installed on
the PPC archictecture, despite it being built.


NB, the root cause here is technically a systemtap (see bughttps://bugzilla.redhat.com/show_bug.cgi?id=772693) , but I don't think we should have a dep on systemtap in libvirt-devel in the first place.

This appears to be coming because we copy the examples/systemtap scripts in %doc. IIUC, if we remove the 'execute' bit from the *.stp files, then the RPM auto-dep extractor should not add this bogus dep.


Version-Release number of selected component (if applicable):
libvirt-0.9.9-1.el6

How reproducible:
Always (on ppc arch)

Steps to Reproduce:
1. yum install libvirt
2.
3.
  
Actual results:
DEBUG util.py:256:  Error: Missing Dependency: kernel-devel is needed by
package systemtap-1.6-4.el6.ppc (build)

Expected results:
libvirt can be installed without pulling in systemtap

Fixed in commit 34364f43e9ddd02f5996aa44b58d52e0753e8064

Permission change for systemtap examples.

Execute bit on *.stp files in examples/systemtap/ caused dependency when building RPM packages. Disabling execute permission should help the auto dependency resolver to see that systemtap is not needed.

Since we have no ppc machine to install libvirt and verify this bug, so just check the dependency of libvirt-devel-0.9.10-1.el6.ppc64.rpm

# rpm -qpR libvirt-devel-0.9.10-1.el6.ppc64.rpm
/usr/bin/pkg-config  
libvirt-client = 0.9.10-1.el6
libvirt-qemu.so.0()(64bit)  
libvirt.so.0()(64bit)  
pkgconfig  
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(VersionedDependencies) <= 3.0.3-1
rpmlib(PayloadIsXz) <= 5.2-1

There no dependency about  /usr/bin/stap, so move to VERIFIED.
