Re: [Twisted-Python] deferred graph?

I'm continuing to have some stuck deferreds - deferredlists probably. I had that graphviz/twisted graphing thing working for some test code, but upon applying it to some deferreds that're getting stuck in some production code, I didn't get the same pleasing output - not entirely surprising. Part o

You should still see the unhandled deferred in your logs if that's truly the case. On Thursday, June 28, 2012, Dan Stromberg wrote: > > Hi. > > I'm a Twisted neophyte, but I've been using Python a long time. > > My question: > Is there a way of producing a deferred graph in a Python program at a

[Twisted-Python] deferred graph?

Hi. I'm a Twisted neophyte, but I've been using Python a long time. My question: Is there a way of producing a deferred graph in a Python program at a given point in time? Perhaps something based on graphviz and objgraph.py? We're able to detect when we're having the problem, we just don't (yet
