Sure, you can find a slightly updated version of the code in the attachment,
licensed under the two clause BSD license and without the syntax error.
Thank you very much for being willing to share this code under the BSD
license. I will try this out and see if it does the job for us.

Fantastic, thanks for sharing this code. I will definitely have a look. If
it turns out to
work for us, would you mind releasing this under a BSD license so we can
include
it in IPython (BSD open source project)? In either case, the ideas will be
very helpful to us.
Cheers,
Brian

Hi,
I have a server-like process that uses twisted. I need it to daemonize
itself and on linux/os x I am simply
using the daemonize function from twistd. This works fine. What about
Windows thoughI saw that the
win32 version of twistd doesn't have (unless I am missing it) the ability to

So
I have been using Twisted for years but only recently began to use
inlineCallbacks (couldn't give up Python 2.4 support until recently). This
simple asynch. sleep function is fantastic. Just today I used to it with
inlineCallbacks to dramatically clean up some complex deferred logic.
Thanks,

Hi,
I know this is not the zope list, but I am encountering this in a twisted
project, so I
wanted to get some ideas here first. I am finding that zope.interface is
like
an infectious disease. Here is a simple example:
In [35]: import zope.interface as zi
In [37]: class A(object):
:
):
...: a = 1 + i
In [2]: %timeit f()
100 loops, best of 3: 8.33 ms per loop
That's depressing...
Cheers,
Brian

Hi,
We use Twisted extensively in the IPython project for parallel and
distributed computing. We have an extensive test suite that uses
trial to test our servers and clients. Everything works
great...but...the test suite takes much longer to run on OS X than
windows. Here is what I mean:

OK, it looks like I solved this. My external program is a python
program. I was starting it without the "-u" flag to Python, which
turns on unbuffered output. Adding the "-u" flag made the error go
away.
I found this tip in the docstrings of the _dumbwin32proc.py Twisted module.

Hi,
[take a deep breath and try to get over how much I dislike Windows]
So, I am using Twisted's external process capabilities in a
cross-platform setting. Almost everything is working now in Windows.
But, when I try to stop the external program (using
signalProcess("INT")) that I starting using
