Cause:
cProfile doesn't output meaningful message when -s option is used without value
Consequence:
when cProfile's option -s is used without value it fails with vague error message
Fix:
when cProfile's option -s is used without value print error valuable error message
Result:
cProfile now prints to stdout all values which -s option supports when not supported is used or forgotten

devel_ack+, we can easily fix this. Is this output sufficient?
> $ python -m cProfile -s sdds.py

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.
