(DBUS/Python) async_callbacks vs. reply_/error_handler

[Jason Heeris]

I'm using the Python/DBUS bindings for asynchronous inter-process
calls in my Twisted/PyGTK app.

I know about using the "reply_handler"/"error_handler" for calling
methods on proxy objects, and connecting to signals, but I've also
read about the "async_callbacks" argument to the dbus.service.method
decorator[1].

The problem is, the section of the docs that should detail this[2] is empty...

So what's the difference? If I have an "async_callbacks" argument in
my service, will a call on the proxy object in another process behave
any differently than if I used the "reply_handler"/"error_handler"
arguments? How can I decide which is best for my situation?

Cheers,
Jason
