Package: python3.2
Version: 3.2.2-4
Severity: important
Dear Maintainer,
In newer versions of Python, it appears pipes cannot be passed from one
subprocess
to another via subprocess.Popen calls; they are still closed even though the
close_fds
arg is specified as False.
I am appending a test script to illustrate the problem. Try running this with
different
versions of Python, and observe the difference: it works fine with 2.6 and 3.1,
and
fails with 2.7 and 3.2.

# Demonstration of misbehaviour of close_fds arg to subprocess.Popen
# on certain versions of Python. This process creates two subprocesses,
# specifying that stdin of the first one is connected to a pipe. That
# pipe should be passed to the second process, but in some cases it's not.
#
# Try this script with various versions of Python, for example
#
# python2.6 test.py
# python2.7 test.py
# python3.1 test.py
# python3.2 test.py
#
# and note the differences in the output. Details on what to look for are
# below.
