Description (last modified by Thijs Triemstra)

I needed to know this and I ended up having to read the source code to learn it. This patch will let the next person learn it from docstrings.

  • twisted/internet/

    === modified file 'twisted/internet/'
    276276        Add a pair of callbacks (success and error) to this L{Deferred}.
    278278        These will be executed when the 'master' callback is run.
     280        Returns self.
    279281        """
    280282        assert callable(callback)
    281283        assert errback == None or callable(errback)
    341343        being returned from a callback, it is possible to cause the call
    342344        stack size limit to be exceeded by chaining many L{Deferred}s
    343345        together with C{chainDeferred}.
     347        Returns self.
    344348        """
    345349        d._chainedTo = self
    346350        return self.addCallbacks(d.callback, d.errback)

(I'll also attach this patch as a unified diff file.)

Thanks for the ticket and patch, zooko!

I added some epytext markup before merging.

(As usual, I failed to move this out of review before closing)
