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++...

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'):

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()

Hi,
I noticed with popen2.Popen4 class, sometimes the poll() method will
keep returning -1 although the command has finished.
However, when a read is done ( ex. p4instance.fromchild.read() ) and
then a poll is done, poll() will return the process exit value.
Why does this happen? perhaps I have to do some type of flush before
doing...

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...

Hi all. I'm trying to execute system commands and capture the output by
using popen4:
stdout example:
>>>exec_cmd = popen2.popen4("echo hello!")
>>>output = exec_cmd.read()
hello
stderr example:
>>>exec_cmd = popen2.popen4("echobv hello!")

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. ...
