I'm guessing that you omitted @inlineCallbacks for navigation, but
that it contains a yield. In Python, that makes it a plain old
generator expression, which ju

This is th
I'm suggesting that there are lots more problems with your code than
the one you have identified. Any method which is decorated with
@defer.inlineCallbacks will return a Deferred, and you need to handle
every Deferred somehow. Generally (although not always, as lvh has
said) you do that by yieldi

And that calls three times self.D, which has a yield.
What is wrong with my reasoning?
Something prevents the inline callback in self.D to wait
That handles the Deferred from subprocess(args), but it doesn't handle
the Deferred from self.C()

Is this true, if I have a yi
True, I only mean that
def A(self):
...
tmp = yield subprocess(args)
...
self.B()
leaves the deferred from B totally unhandled, which is nearly always a
bad thing.

I still believe that making those dependencies visible is a good idea.
At any rate, in your original code:

Async programming aside, this mode of chaining multiple methods
doesn't sit well with me:
def A()
# .. do stuff
B()
def B()
# .. do stuff
C()
I think it'd be more idiomatic to have a controlling method that
indicates the chaning:
def do_stuffs():
A()
B()
C()
D()
D()
D()
