My application starts up a number of processes for various purposes using:
self.popen = popen2.Popen3("/usr/local/bin/python -O "myscript.py")
and then shuts them down when appropriate with
os.kill(self.popen.pid, signal.SIGTERM)
Everything works fine on MacOSX. However, I'm doing a port to Solaris (so I
can run it on my web site) and find that the child processes are not
stopping! Solaris is creating TWO new processes: one for the SHELL...

I'm running a monitoring script under linux written in python. It's nohup'ed so
that I can log out and it will continue running happily and so on, but
sometimes I need to kill the script before editing the source and relaunching it.
Question is, what's the nicest way to kill the python process under linux? Is a
simple 'kill ' the nicest way to do it, or is there a different
signal I should send it?

I got this to work, but was hoping there was a better way. I was
hoping that I wouldn't have to use globals. I wouldn't doubt that I
could be totally off in what I am doing.
Here is some psuedo-code of what I did:
def main_thread():
# Don't know how to get rid of these guys
global lock

Hello,
I catch SIGINT signals with a handler.
In the handler, I use fd's to write some data to a child process.
Is this valid?
Because the data never arrives, and I wonder what I'm doing wrong.
Can filedescriptors still be used when you're in the signal
handling of SIGINT?

Hi,
I am working on an application which involves
interprocess communication. More to the point,
processes should be able to notify other processes
about certain situations, so the "notifyees" would be
able to act in certain ways.
As processes are distributed on several machines, in
different physical locations, my thinking was:

I am trying to write a program that will fork a process, and execute the
given task... the catch is that if it runs too long, I want to clean it up.
this seemed pretty straight forward with a single executable being run
from the fork. The problem I am having now is that if I call a shell
scripts, then lets say calls "xterm &", after the timeout has occurred,
I kill the shell script, but the xterm is still running... I cannot seem
to kill...

Suppose we spawn a child process with Popen. I'm thinking of an
executable file, like a compiled C program.
Suppose it is supposed to run for one minute, but it just keeps going
and going. Does Python have any way to kill it?
This is not hypothetical; I'm doing it now, and it's working pretty
well, but I would like to be able to handle this run-on condition. I'm
using Windows 2000, but I want my program to be portable to linux.

Hi Fellows,
I have a problem with process termination. I have a python code that
apache runs through a django interface.
The code is very simple, first, it creates a process with the
subprocess.Popen call, and afterwards, (using a web request) the
python code uses the PID of the previously created process(stored in a
db) and kills it with an os.kill call using the SIGKILL signal.
The creation of the process is ok, apache calls the...

Hi!
I waste a lot of my time figuring why this snip of code doesn`t work.
And still without any solution ;/
Does anybody know why this handler cannot handle SIGINT signal? What
did I wrong?
Thanks in advance.

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Overview:
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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
