[New-bugs-announce] [issue3234] subprocess.py strips last character when raising an AttributeError

[Martin Mokrejs]

New submission from Martin Mokrejs <mmokrejs at users.sourceforge.net>:

I try to get working pipe emulation using Popen. I try to pass StringIO
object to p1.stdin of the first process and I got the following:

  File "/usr/lib/python2.5/subprocess.py", line 587, in __init__
    errread, errwrite) = self._get_handles(stdin, stdout, stderr)

  File "/usr/lib/python2.5/subprocess.py", line 932, in _get_handles
    p2cread = stdin.fileno()

AttributeError: 'cStringIO.StringI' object has no attribute 'fileno'

Aside from the fact I would hope that cStringIO could provide
self.fileno() I believe the error message should have been:

AttributeError: 'cStringIO.StringIO' object has no attribute 'fileno'
