Very, very close to want I wanted to understand, thank you!
One more q please: what if I complicate the abc1() like following, is
this expected to work or again I've missed the point?
return (
self.abc1().
addErrback(self.handleFailure1).
addCallback(self.abc2,

Thank you a lot for pointing me to the Twisted doc-s, but we're
discussing the following snippet:

me too,
may be its because of the way I'm calling the chain:
return (
self.abc1().
addErrback(self.handleFailure1).
addCallback(self.abc2,args).
addCallback(self.abc3).

Add another .addErrback() directly after adc1() - to handle that
specific exception...

hi,
how can I chain in defer methods that could raise exception while
showing the exception that coming from method? I mean, if I'll do:
return (
adc1().abc2().abc3().addErrback("Common2AllException")
)
than "Common2AllException" will be raised if abc1() raise Exception,
but I'd like to see
