[Pharo-users] Network data exchange - Basys and Seamless usage questioning

Hi all and Denis, I’ve played a bit with Basys and Seamless. Basys is the low level P2P connection framework used by Seamless. First, thanks for such works. Heavily documented and tested. That’s super cool. My objective is to have several images running (one representing one app belonging to one or more singular entity realm). Lets say image A1, A2, A3 belongs to Alice. And image B1, B2, … to Bob. They exchange messages conveying information. So the aim of the network layer is for me to keep messages synchronized betweens A(s) and B(s). I have inbox and outbox for that. This is actually quite close to the basys abstractions on LocalPeer and RemotePeer (active and passive). So I played a bit with basys and can declare a network between A1 and B1 for instance. I wonder if I need as much network as possible connection (A1B1 A1B2 … but also A1A2, A1A3, A2A3, …). Not sure how to declare network with more than 2 nodes… I can send string message, and eventually binary. I think I may implemented proper message send. Then, there is seamless that is based on basys and that is far more complete. Several transport and message send possibilities, distributed object with proxy remote delegation, etc. I could use seamless but I find it goes too far for my purpose (it can actually execute code in the remote image - I don’t want that, at least by default). At first I don't want to execute code on the peer, only send message to it and received message form it (some of this message could be code invocation but actually more in a business process manner, meaning I activate an activity, but code run locally). This being said, do you think 1) it’s better to use Basys and subclass BasysNetwork (I used BasisNetworkStub) ? I just send message serialization ? 2) or may I use Seamless straight with restrictions (I wonder if limiting the classes that can be executed would suffice - proxies should only be on the peer inbox and outbox I think) ? 3) or maybe I should do a lighter version of seamless ? If so where should I look at/change ? TIA, Cédrick
