            Bug ID: 18114
           Summary: stap-prep on fedora 20 incorrectly identifies kernel
                    debug RPM to install
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: server
          Assignee: systemtap at sourceware dot org
          Reporter: gurunixx at gmail dot com

Created attachment 8184

change definition of kernel debug RPM for fedora 20

stap-prep cannot succeed on Fedora 20, 64-bit because the kernel debug package
name is not found. 

Patch attached.  I have only tested this on Fedora 20 64-bit, but it should
work on 32-bit too.

Note that the stap-prep script is present in /two/ packages - though yum does
not report a conflict...!

systemtap-devel-2.7-1.fc20.x86_64
systemtap-client-2.7-1.fc20.x86_64

* N.B.  Where the heck is livna?! The site at http://rpm.livna.org/ is
completely empty.  I downloaded the RPMs from rpmfind but I think they should
have been available via livna - google does not know what's happened, no one
has even asked. If livna WOULD have provided
'kernel-debuginfo-3.18.7-100.fc20.x86_64' instead of my having to download
'kernel-debug-debuginfo-3.18.7-100.fc20.x86_64' manually, then this bug should
probably be rejected :-( 

In any case, I'm now working here.

Please note that kernel-debug and kernel are two different builds of the
kernel, each with its respective -debuginfo available (kernel-debuginfo &
kernel-debug-debuginfo).  So the situation is not quite as simple as the
proposed patch makes it seem.

Thanks, Frank.  Do you think this is possibly related to Livna going away,
then? 

I do see a kernel-debuginfo package at
http://rpm.pbone.net/index.php3/stat/4/idpl/28873657/dir/fedora_20/com/kernel-debuginfo-3.18.7-100.fc20.x86_64.rpm.html

Your guidance is appreciated.

I don't think livna is related at all.  Fedora RPMs and associated -debuginfo
rpms are all served from fedora servers, not from livna etc.  It is possible
that the version you're running is old enough to have aged out of the "current"
set visible via yum etc.  In this case, it may be necessary to go to
http://koji.fedoraproject.org/koji/packageinfo?packageID=8 to dig up the
matching build amongst the other fossils.  I don't know of a mechanical way to
do so. :-(

stap-prep appears to work here with -debug and non-debug kernels on f22.
