Daemon process

[Shan]

I have XML RPC Server listening on a port. This XML RPC Server works
fine when i run it as foreground process. All the clients are able to
connect with the XML RPC Server. But when i run it as daemon(not using
&. I am doing it in python way only), then no clients are able to
connect with the Server. I didnt got any clue where i may be  wrong.
Can any help me with this? I am using python 2.4 on Redhat 5.2 64
X86_64


Thanks,
Shan

Repeating Thread Error

[Jonathan Shan]

Hello,

I am trying to call a function every 5 seconds. My understanding of
time.sleep() is during the sleep time everything "stops". However, in
my application, there are background processes that must be running
continuously during the five second interval. Thus, threading.Timer
seems like a good function. Here is the relevant code:

# background processes
t = threading.Timer(5.0, function_name, [arguments])
while True:
 # Do background processes run inside while loop?
 t.start()

The above code generates an error:
AssertionError: thread already started

Any hints on how to fix the error? Also, do background processes run
inside while loops?

Thanks in advance,
Jonathan Shan

Array and floating point

[Jonathan Shan]

Hello,

I'm experiencing a problem where the float being appended to the array
is not the same as the result of the appending.

>>> from array import *
>>> x = array('f')
>>> x.append(float("0.1"))
>>> x[0]
0.1000149011612
>>> float("0.1")
0.10001

I'm expecting x[0] = 0.10001

Thanks
Jonathan Shan

If nothing else, please use Google.  Many will thank you.
