Hi again Glyph, Andrew
Below is a simpler and more flexible ControllableDeferred class.
The idea is simple: you want a deferred that you can call/errback yourself,
and which you can also deactivate so that it never fires. This is done by
manipulating two normal deferreds (self, and a deferred re
Argh. sorry, there was a trivial cut & paste error in the code I just
posted. The errback method should of course be:
def errback(self, fail=None):
if not self._called:
self._called = True
defer.Deferred.errback(self, fail)

Hi Devraj,

Yes it is possible. Simply start the reactor in a thread, but run it as:
reactor.run(installSignalHandlers=False)
If you do it this way you're going to have to handle signals yourself.
You're going to have

The thing is, this attitude isn't always reasonable. Deferred is not
necessarily the place to implement

Hi, we're trying to using pyinstaller to create single-directory
distributions of our Twisted/python server on Linux. Wondering if anyone has
accomplished this? I googled and checked the archives, but there seems to be
no concrete information available.
I'm real new to pyinstaller and not really f
