Attempting to read from stdout of a running process seems broken on Python3.2. I've been able to reproduce this on Ubuntu 11.4 and Windows 7 (with /bin/sh installed as part of git for windows)
Python 3.2 (r32:88445, Dec 8 2011, 15:26:51)
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from subprocess import Popen, PIPE
>>> p=Popen(["/bin/sh"], stdin=PIPE, stderr=PIPE, stdout=PIPE)
>>> p.stdin.write(b"echo hello\n")
11
>>> p.stdout.readline()
<stuck>
>>> from subprocess import Popen, PIPE
>>> p=Popen(["/bin/sh"], stdin=PIPE, stderr=PIPE, stdout=PIPE)
>>> p.stdin.write(b"echo hello\n")
11
>>> p.stdout.read(2)
<stuck>
For comparison, on python 2.7 (again, linux and windows:
Python 2.7.1+ (r271:86832, Apr 11 2011, 18:05:24)
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from subprocess import Popen, PIPE
>>> p=Popen(["/bin/sh"], stdin=PIPE, stderr=PIPE, stdout=PIPE)
>>> p.stdin.write(b"echo hello\n")
>>> p.stdout.readline()
'hello\n'
