[Python bindings] Unable to convert function return value to a Python type! when accessing caf::node_id about broker HOT 1 CLOSED

When trying to access a field of type caf::node_id e.g. through a status update (status.context().node) Python exits with the error in the title.
As the error says the type from libcaf cannot be converted to a Python object, which makes sense, as broker does not ship with libcaf Python bindings.

Is this intended behaviour? If so then the caf types should probably not be exposed to Python at all (see: _broker.cpp).

I just removed the EndpointInfo.node() method as to minimize how much the CAF dependency is exposed here.

We would really like to use the node id in our project though, is there any supported way of doing so?
For the moment we discovered that context.__repr__ looks like it contains the node id, which lets an endpoint identify its peers (on status updates) but as Endpoint::node_id is not bound at all the endpoint cannot get its own id.

Yes, I agree being able to obtain the node ID string is helpful. Via
df6525e, there's now the additional repr() available for Endpoint that prints a node ID, and additionally I've just made explicit node_id() methods for both Endpoint and EndpointInfo.

This is just one example of unconvertible objects. endpoint.peers() is unable to convert std::vector<broker::peer_info, std::allocator<broker::peer_info>>. Unfortunately we are not sure if this happens because of the vector itself, broker::peer_info or the std::allocator.

This should be fixed via 7582523.
