Fredrik,

could you check whether the get_machine_details() function is causing the hand on your machine ?

Does anyone else observe this as well ?

I'm about to check in version 2.0 of pybench, but would like to get this resolved first, if possible.

Thanks,

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 ------------------------------------------------------------------------------- * using Python 2.4.2 * disabled garbage collection * system check interval set to maximum: 2147483647 * using timer: time.time Calibrating tests. Please wait... Running 10 round(s) of the suite at warp factor 10: * Round 1 done in 6.627 seconds. * Round 2 done in 7.307 seconds. * Round 3 done in 7.180 seconds. ... 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 getmachinedetails(): import platform buildno, builddate = platform.pythonbuild() python = platform.pythonversion() 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.pythonversion(), 'compiler': platform.pythoncompiler(), 'buildno': buildno, 'builddate': builddate, 'unicode': unicode, 'bits': bits, } It does run fine on my WinXP machine, both with the win32 package installed or not.
