Summary: wrong socket error returned
Initial Comment:
hi,
first, background:
OS: OpenBSD-current/i386
Python version: 2.3.4
example script:
import socket
socket.setdefaulttimeout(30)
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1', 9999))
where nothing is listening on 9999 (ECONNREFUSED
should be returned).
when ran it i get:
Traceback (most recent call last):
File "bug.py", line 8, in ?
s.connect(('127.0.0.1', 9999))
File "<string>", line 1, in connect
socket.error: (22, 'Invalid argument')
this is a problem in the socketmodule.c, in the
internal_connect() function. getsockopt with SOCK_ERROR
should be used once EINPROGRESS is returned to get the
real error.
this code works on linux, but the connect semantic
is, imho, broken. you cannot reuse a socket once it
failed (a test afterwards shown that this is valid
under linux!!!!).
please contact me if you need further details,
although i find this very clear.
thanks,
f.-

patch against 2.4.1 appended. not tested in anything but
openbsd. nevertheless, i think it should work in linux and
osx. not sure about others.
cheers.

just tried this with 2.4.1 running in OpenBSD 3.7/amd64 and
the problem is still there :-(

maybe i was not clear. the problem is only happening when
setdefaulttimeout is used. otherwise ECONNREFUSED is
correctly returned.
