Hi,
Been working with pycapnp a while now. And when it works, it is really
nice, but when I make a mistake, it can be a bit hard to track down what
went wrong (the stack traces on the form of hex addresses doesn't help me
much, or I just don't know which tools to apply on them).
I have two questions,
a) Consider the following schema snippet:
interface Foo {
meth @0 (a :Text, b :Bar) -> ();
}
interface Bar {
}
Is there any way to make the b parameter optional, or accept None as input
when invoking it, on the python side?
b) Using RPC, is there any way on the server side to detect when a client
disconnects?
Now I find myself relying on __del__ being called on server interfaces I've
created and sent to the client (but that only works if I refer from holding
a reference to it myself, and weak refs doesn't seem to work on these
little buggers) ;)
And if yes, how to identify the client in question.
Thanks.
