read and readline hanging

Olivier Lefevre

1/24/2008 11:05:00 PM

I am calling subprocess.Popen with
p = Popen(args, bufsize=-1, stdin=PIPE, stdout=PIPE, stderr=PIPE)
and after sending come command to the process, I try to read
from p.stdout but after a few calls I hang. What is the correct
way to do this, i.e., to read everything w/o getting stuck? I am
not familiar with all these low-level functions and their annoying
blocking behaviour. Note that I don't want to close the process
because I want to send more commands to it after that, read the
results, and so on and on.

Thanks,

-- O.L.

You are a death fetishist. According to your posts, someone's death is
the requisite response to anything and everything you happen not to
like. I realize that, in real life, you're a harmless little fellow,
but you're not a healthy or well-adjusted one.

Can you describe this "left wing police state" of you're imagining?

How do you account for the fact that discussion of the actual,
barbaric practices of organized religion is subject to a complete ban?
It cannot be a result of quasi-theocratic police-state policies, now
can it?

I don't. You're fantasizing or hallucinating.

Christians have cleaned upthier act considerably.

Islam continues to commit atrocities which are well documented.

Life is not a bad adolescent scifi novel.

Well that pretty well substantiates your opinon on this and any other
subject. You fully explained the original subject and nicely filled in
the details with substantiated facts.

Do post again if you get an actual thought on something.

Why do I think Plimpton has yet another new name?

Ok. A trivial example: the obvious fraud associated with television
evangelists who exploit the naive. And it is a knowing fraud. But
all they have to do is say they believe and apologists like you accept
them at their word.

> Christians have cleaned upthier act considerably.

They've learned to "work" in secret as much as possoble, if that's
what you mean. My favorite method is their deliberate incompetence
whereby they do harm even as they pretend to have good intentions.

Of course, people like you have no idea why conditions so rarely
improve and nearly always get worse. Such a mystery.

> Islam continues to commit atrocities which are well documented.

Different in kind, but not necessarily degree.

> Life is not a bad adolescent scifi novel.

Fuck you and the straw men you rode in on.

Because you are wracked with paranoia and fear after the last few
thrashings he has administered upon you.
