To support scheduling calls, you just have to know when the next call is
going to happen. Then, you can wake up at exactly that time. This is
what Twisted does, even for select reactor. ;)
Yes but how do you know when it's the time to fire up a call without
using a thread?
You are forced to call time.time() periodically and check if that time
had come every time.
Take a look at twisted/internet/base/ReactorBase.run UntilCurrent.
That's where that should happen.
Why? Isn't this why subtraction exists? If there is a call scheduled to
happen at T1 and the current time is T2, then I know that after (T1 - T2)
elapses, it will be time to run the call. Why do I have to do any checks
at all? I just tell select() to wait that long. Presumably this is just
what someone will do if they want to use asyncore with timed calls. Call
asyncore.loop( ) in a loop, always passing (T1 - T2) as the timeout value.
Ah, of course this is wrong, since asyncore.loop.. . loops. :P I meant to
say asyncore.poll() here.
>So, actually, I'm not sure what the disagreement is about. ;) The
default value for the timeout parameter to the loop function seems
somewhat irrelevant. If someone wants timed events in their loop,
asyncore isn't standing in their way. On the other hand, I didn't
this thread (or maybe just this part of the thread) start out with
a question about asyncore throughput? I have no idea what that
might have to do with this.

I've embarked on a small learning project, trying to get a better grasp of

I got my server portion working well, and I think I understand the basics.

Hello,
I'm using Python's asynchat module for network support in a Python-based
game, and I run into two problems, both of which occur at random times.
Most of the time, the network sending and receiving is perfect, but
about 1 out of 10 times, it fails with one of these errors:
-- Problem 1. When sending data, I sometimes the following exception:
Handler connected 127.0.0.1:1242 at 0x2977800> (socket.error:(9, 'Bad

Hi again,
I'm using Python's asynchat module for networking.
When calling the sendall() method of asynchat,
I sometimes get the error message "the operation
could not complete without blocking".
So how do I enable blocking with synchat, or otherwise fix this error?
Thanks for the help I've received with asynchat so far in this news group.

I can not get error notifications when an asynchat based client tries to
connect to a non-responsive address.
To validate the problem I changed lib/test/test_asynchat.py as follows:
class echo_client(asynchat.async_chat):
def __init__(self):
asynchat.async_chat.__init__(self)
self.create_socket(socket.AF_INET, socket.SOCK_STREAM)

My question concerns asynchat in particular. With the following half-

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:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
