New Systemtap-0.8 RPM available for testing on Fedora 8 and Fedora 9

[William Cohen]

Hi All,

If you are like Roland  and looking for a newer version of the Systemtap RPMs 
for Fedora, you are in luck. The newer Systemtap 0.8 RPMs are now available for 
testing on Fedora 8 and Fedora 9. There is also a request for  Fedora 10 but the 
rpms haven't been pushed to the F10 repository:

https://admin.fedoraproject.org/updates/F8/FEDORA-2008-9787
https://admin.fedoraproject.org/updates/F9/FEDORA-2008-9695
https://admin.fedoraproject.org/updates/systemtap-0.8-1.fc10


The RPMs can be installed on a fedora 8/9 machines with:

yum install --enablerepo=updates-testing-newkey systemtap

Or the RPMs can upgraded with:

yum upgrade --enablerepo=updates-testing-newkey "systemtap*"

Please check to see that the newer version of systemtap works as expected and 
report your results on the update URLs towards the top of this email.

Nice! Have tested a bit against the latest f9 kernel,
2.6.27.5-41.fc9.x86_64 Seems to work fine. And the user probes working
out of the box now is great.

I couldn't figure out how to run the tests against the
systemtap-testsuite package. Would like to run those to see how things
look in the larger picture. How do you run them from the rpm?

One usability nit. If you have setup a stapdev group then if you run
anything with user probes for the first time you will get:

  SystemTap's version of uprobes is out of date.
  As root, run "make" in /usr/share/systemtap/runtime/uprobes.
  Pass 4: compilation failed.  Try again with more '-v' (verbose)
  options.

While running it if you are in sudoers with sudo, will just
automagically do the right thing for you without any manual
intervention. Not so much a bug, just a strange usability issue.
I don't know much about packaging, but would it be possible to rebuild
uprobes whenever a new kernel or systemtap rpm is installed?

Cheers,

Mark

Install systemtap-testsuite rpm.  cd /usr/share/systemtap*/testsuite.
make *check.

Let's discuss further in PR5163.

Doh. That was too easy. Should have figured that out myself.
Results of sudo make installcheck look good:

Hi Mark,

Thanks for giving it a test and making a comment about it on the updates webpage.

It looks like the karma score is only affected by comments from people actually 
logged into bodhi (and only one thumbs up or thumbs down per log in). However, 
that is really minor. Just need two more people to give thumbs up for it to be 
pushed automatically to stable with Karma of 3. Of course it can always be 
manually pushed to stable.

Hi Everyone,

Testing them should be very easy, install the systemtap-testsuite rpm.
Go into the /usr/share/systemtap/testsuite directory.
As root "make installcheck"

If you want to automatically send the results to dejazilla, use:

make installcheck DEJAZILLA=dejazilla@elastic.org
