Repy unit tests do not run correctly on Ubuntu 11.10

[choksi81]

On Ubuntu 11.04, x86_64, with Python 2.7.1+ the repyv2api unit tests all pass. They also pass with Python 2.7.2, compiled from source.

On Ubuntu 11.10, x86_64, with Python 2.7.2+, some of the unit tests fail with a message:

Exception exception_hierarchy.RunBuiltinException: RunBuiltinException() in <bound method Popen.__del__ of <subprocess.Popen object at 0x1dbe6d0>> ignored

The problem appears to be related to socket.close(), as commenting out s.close() in the following code allows it to pass the test properly:

#This unit test checks the sendmessage() API call.

#pragma repy
#pragma repy restrictions.twoports

s = listenformessage('127.0.0.1', 12345)

data = "HI"*8

sendmessage('127.0.0.1', 12345, data, '127.0.0.1', 12346)

(rip, rport, mess) = s.getmessage()

s.close()

if mess != data:
  log("Mismatch!",'\n')

mkaplan: On examining subprocess.py on Ubuntu 11.10, Popen.__del__ calls getattr.

Adding a traceback:

It seems that subprocess requires getatrr to be made available. Adding the following line to safe.py allows the code to run without a problem:

subprocess.getattr = getattr
