RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHBA-2011:0651 0 normal SHIPPED_LIVE systemtap bug fix and enhancement update 2011-05-19 09:37:25 UTC

Description Petr Muller 2011-03-29 09:35:07 UTC 
Description of problem:
The RHEL6.1 candidate systemtap packages FAIL in systemtap.base/bench.exp testcase, while the 6.0.z systemtap PASSes here. 

Version-Release number of selected component (if applicable):
Environment:
kernel-2.6.32-122.el6
elfutils-0.152-1.el6
systemtap-testsuite-1.4-4.el6

Systemtap:
systemtap-1.2-11.el6_0 PASS
systemtap-1.4-4 FAIL

How reproducible:
always

Steps to Reproduce:
1. cd /usr/share/systemtap/testsuite/
2. make RUNTESTFLAGS=systemtap.base/bench.exp installcheck
3.
  
Actual results:
FAIL

Expected results:
PASS

Additional info:
The FAIL seems to be caused by the change of output, so it's perhaps just the testcase problem. Old systemtap's output was a bunch of lines in this format:

probe test.null (/usr/share/systemtap/testsuite/systemtap.base/bench.stp:12:45), hits: 40, cycles: 119min/127avg/168max

while new systemtap has 40 lines for each old one in this format:

begin, (/usr/share/systemtap/testsuite/systemtap.base/bench.stp:12:19), hits: 1, cycles: 147min/147avg/147max, from: begin from: repeat from: test.null
Comment 1 Petr Muller 2011-03-29 11:25:36 UTC 
similar problem caused a PASS->FAIL transition for systemtap.base/skipped.exp:

Comment 2 David Smith 2011-03-29 20:47:08 UTC 
Those two tests hadn't been updated with changes to the probe timing report output changes.  Fixed in the following upstream commit (which will need to be backported):

Comment 3 RHEL Program Management 2011-04-04 01:54:34 UTC 
Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
Comment 5 Frank Ch. Eigler 2011-04-06 15:08:43 UTC 
Trivial test case hack in hand.
