http://www.egenix.com/files/python/pybench-2.0-2006-06-09.zip believe it or not, but this hangs on my machine, under 2.5 trunk. and it hangs hard; nether control-c, break, or the task manager manages to kill it.

Weird.

if it's any clue, it prints

------------------------------------------------------------------------------- PYBENCH 2.0 ------------------------------------------------------------------------------- * using Python 2.5a2 * disabled garbage collection * system check interval set to maximum: 2147483647 * using timer: time.clock and that's it; the process is just sitting there, using exactly 0% CPU.

This is the output to expect:

PYBENCH 2.0

Calibrating tests. Please wait...

Running 10 round(s) of the suite at warp factor 10:

Note that the calibration step takes a while.

Looking at the code, the only place where it could hang (because it's relying on a few external tools) is when fetching the platform details:

def get_machine_details():

import platform
buildno, builddate = platform.python_build()
python = platform.python_version()
if python > '2.0':
    try:
        unichr(100000)
    except ValueError:
        # UCS2 build (standard)
        unicode = 'UCS2'
    else:
        # UCS4 build (most recent Linux distros)
        unicode = 'UCS4'
else:
    unicode = None
bits, linkage = platform.architecture()
return {
    'platform': platform.platform(),
    'processor': platform.processor(),
    'executable': sys.executable,
    'python': platform.python_version(),
    'compiler': platform.python_compiler(),
    'buildno': buildno,
    'builddate': builddate,
    'unicode': unicode,
    'bits': bits,
    }

It does run fine on my WinXP machine, both with the win32 package installed or not.
