We have a python+Tkinter program that works properly on
Linux, but when moved to Windows (XP) it behaves in a
strange way. There's a section like this:
(child_out, child_in) = popen2.popen4(cmd)
line = child_out.readline()
while line:
do_something_with(line)
line = child_out.readline()

We have an application that works on Linux. It has to be ported
to Windows XP, and there's one bug that's driving me crazy.
There's a number-crunching program written in C++. It is invoked
by a Tkinter python script. The script uses the threading
module to separate out the heavy processing. The worker thread
uses popen4 to run the C++ program and capture its standard
output. This output is sent to the master thread through a
queue...

Hello,
I use popen2.Popen4 and I experienced problems with it. Let me show you with
an example. The following script is called "lines" (it prints lines of
'X'):
---------------------
#!/usr/bin/env python
import sys

Hi, I'm using popen2.Popen4 and I'm curious what exceptions it could
raise
for example
p = popen2.POpen4( 'command string' )
i'm assuming would only raise OSError exceptions if something went
wrong internally with popen.
and also, for read operations like:
p.fromchild.read()

I'm having trouble with Popen4 locking up on me. It appears to be
unrelated to the actual command I'm running, because I made the command
just "cat" (I'm on UNIX) to echo whatever input I sent it, and it's still
locking. The trick is, it works for small amounts of data. After roughly
1.5K of input, it locks up and will not write any more data to the pipe.
I assume a buffer got full somewhere, and it's blocking the write call.

Hi all,
I know it's a kind of bizarre question but here I go: I want to
execute an script using popen4. This script executes a command in turn
using popen4 too. The first one throws a 256 exit code.
Any suggestions?
Thanks
J.

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
