Hi Tom

in a GUI application I'm using quite a comprehensive chain of deferreds and I'm running the mainloop from the glib2reactor. At a certain point of my application I need to terminate the entire chain of deferreds to make sure that no more data is loaded and processed. Stopping the reactor does not work as the entire GUI would terminate, too. I tried to cancel the first deferred, hoping that the cancel event will be forwarded to the next deferred in the chain or at least invoke an errback, but for some reason it does not work and the deferreds seem to run forever. Any ideas on how to solve this issue?

It's a bit hard to know how to help without more detail. Code you paste some code somewhere? I'm sorry if this sounds picky, but your description is a bit vague. E.g., there's no such thing as a "chain of deferreds" (do you mean chain of callbacks on a single deferred? or a callbacks that return deferreds etc?) and e.g., "deferreds seem to run forever" but deferreds don't run at all, callbacks do. If you can make it a bit more precise I'll be happy to try to help. Terry
