[New-bugs-announce] [issue10397] Unified Benchmark Suite fails on py3k with --track-memory

[Bobby Impollonia]

New submission from Bobby Impollonia <bobbyi at gmail.com>:

Steps to reproduce (requires linux because the --track-memory (-m) option to perf.py is linux-only):
hg clone http://hg.python.org/benchmarks/ py2benchmarks
mkdir py3benchmarks
cd py3benchmarks
../py2benchmarks/make_perf3.sh ../py2benchmarks
py3k perf.py -f -m -b normal_startup old_py3k new_py3k

With --track-memory, the normal_startup benchmark (which is part of the py3k benchmark group) invokes the interpreter under test as:
py3k -c 'for _ in xrange(200000): pass'

This fails on py3k due to the use of xrange, which is not caught by 2to3 since it appears inside a quoted string (the command line argument).

A patch is attached that resolves the issue by changing the for loop with xrange into a while loop.
