I have set up a socket listener that needs to listen indefinitely. On an
incoming call I get a connection object that I want to set a timeout on
[Win2k, Py2.3.2]. As the setdefaulttimeo ut method did not work with the new
connection I found (using dir on the socket._socket object) a settimeout
method. Is this (undocumented) method peculiar to Windows or fully
cross-platform?
code fragment:
conn = rcv.nextConnAdd r()
print conn
print
print dir(conn[0])
conn[0].settimeout(30. 0)
rcv.rxThread(co nn)
output:
(<socket._socke tobject object at 0x0095B7E0>, ('10.10.192.240 ', 3524))
['__class__', '__delattr__', '__doc__', '__getattribute __', '__hash__',
'__init__', '__module__', '__new__', '__reduce__', '__reduce_ex__' ,
'__repr__', '__setattr__', '__slots__', '__str__', '_sock', 'accept',
'bind', 'close', 'connect', 'connect_ex', 'dup', 'fileno', 'getpeername',
'getsockname', 'getsockopt', 'gettimeout', 'listen', 'makefile', 'recv',
'recvfrom', 'send', 'sendall', 'sendto', 'setblocking', 'setsockopt',
'settimeout', 'shutdown']

Hi Python Gurus!
Here is a method I used before to receive data over a socket (with
Python 2.2):
SELECT_GRANULARITY = 0.1 # 0.1 seconds
def readdata(self,length,timeout):
res = ''
remain = length

Python2.3.2: Running the following receiver and sender code in separate
windows under Win2K does not work properly (missed & very delayed
transmissions). Under Redhat Linux 9 (where I will be using it) it works
fine (with up to 250 sending threads; I hit the thread limit at 255!)
Any idea why do I not get any errors reported under Windows?

My problem is not really python specific but as I do my implementation
in python I hope someone here can help me.
I have two programs that talk through a socket. Here is the code :
<server>
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
sock.settimeout(5.0)

Hi,
I have a gui (made in wxPython) that enables a user to connect to a server
and issue some commands. The problem occurs when i try to disconnect the
client. It exits but it doesn't return to the prompt. I have to push
Ctrl-C in order to have it exit completely. The GUI is closed though.
This is a piece of code from the main class that connects to the server
and starts a thread that handles the connection:

Hello,
Ok, here's my situation. I have a small application that listens to
messages on a UDP port.
When I pass None to settimeout(), and I hit Ctrl+C to interrupt the
wait my exception handler catches the KeyboardInterrupt exception.
However, if I pass any value to settimeout() the exception is not
caught.

Does anyone know the scope of the socket.setdefaulttimeout call? Is it
a cross-process/system setting or does it stay local in the application
in which it is called?
I've been testing this and it seems to stay in the application scope,
but the paranoid side of me thinks I may be missing something... any
confirmation would be helpful.

When using socket.socket.settimeout we normally only guard against
"socket.timeout" exception.Now the implementation of "settimeout" in
"Python-2.4.3/Modules/socketmodule.c" sets the socket fd to
nonblocking and uses "select()" to timeout
as seen below in line 1487 and 1386 :
static PyObject *
1470 sock_settimeout(PySocketSockObject *s, PyObject *arg)
1471 {
1472 double timeout;

While doing a netstring implementation I noticed that if you
build a record up using socket's recv(1), then when you close
the remote end down, the recv(1) hangs, despite having a short
time out of 0.1 set.
If however, you try to receive more than one char, (I tested with 3,
did not try 2), then when you shut the remote end down you do not
get a time out, but an empty string - the normal end of file, I suppose.
Has anybody else seen...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
