New submission from Łukasz Langa <luk...@langa.pl>:
Tested on Python 3.2a0 on Mac OS 10.6.4.
When you specify the most basic `file_dispatcher` and run the loop,
`file_wrapper` fails because it doesn't provide the `getsockopt()` to fake
being a socket.
The code
--------
import asyncore
import os
class FileDispatcher(asyncore.file_dispatcher):
def handle_read(self):
data = self.recv(8192)
fd = os.open('/etc/passwd', os.O_RDONLY)
s = FileDispatcher(fd)
os.close(fd)
asyncore.loop(timeout=0.01, use_poll=True, count=2)
Expected result
---------------
None, it should run OK silently.
Actual result
-------------
error: uncaptured python exception, closing channel <__main__.FileDispatcher at
0x100524e10> (<class 'AttributeError'>:'file_wrapper' object has no attribute
'getsockopt' [/opt/error-report/py3k/Lib/asyncore.py|readwrite|106]

os.close(self.fd)
OSError: [Errno 9] Bad file descriptor
Patch
-----
Please find attached a patch that does add a unit test for this specific case
and adds the most simple `getsockopt()` possible that is still reasonable. The
patch was made with trunk r83090.
