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.

Description Alexander Todorov 2014-11-05 10:02:41 UTC 
Description of problem:

I've forgotten to add the sort value to the -s option of cProfile which results in a traceback instead of user friendly error message. In the example below hello.py just prints a "Hello World":


$ python -m cProfile -s hello.py
Traceback (most recent call last):
  File "/usr/lib64/python2.6/runpy.py", line 122, in _run_module_as_main
    "__main__", fname, loader, pkg_name)
  File "/usr/lib64/python2.6/runpy.py", line 34, in _run_code
    exec code in run_globals
  File "/usr/lib64/python2.6/cProfile.py", line 190, in <module>
    main()
  File "/usr/lib64/python2.6/cProfile.py", line 185, in main
    parser.print_usage()
  File "/usr/lib64/python2.6/optparse.py", line 1597, in print_usage
    print >>file, self.get_usage()
  File "/usr/lib64/python2.6/optparse.py", line 1583, in get_usage
    self.expand_prog_name(self.usage))
  File "/usr/lib64/python2.6/optparse.py", line 1560, in expand_prog_name
    return s.replace("%prog", self.get_prog_name())
  File "/usr/lib64/python2.6/optparse.py", line 1555, in get_prog_name
    return os.path.basename(sys.argv[0])
IndexError: list index out of range

Version-Release number of selected component (if applicable):
python-2.6.6-52.el6.x86_64

How reproducible:
always


In addition to this the list of possible sort values is not available and one needs to dig into the code to figure it out.
Comment 2 Bohuslav "Slavek" Kabrda 2014-11-25 07:14:48 UTC 
devel_ack+, we can easily fix this.
Comment 3 Robert Kuska 2015-02-09 11:34:05 UTC 
Is this output sufficient?

> $ python -m cProfile -s sdds.py                                                                                                     
Usage: cProfile.py [-o output_file_path] [-s sort] scriptfile [arg] ...

cProfile.py: error: option -s: invalid choice: 'sdds.py' (choose from 'cumulative', 'module', 'ncalls', 'pcalls', 'file', 'line', 'name', 'calls', 'stdname', 'nfl', 'filename', 'cumtime', 'time', 'tottime')
