DRb Questions

Ruby
1

I’ve seen a couple of tutorials now claim that both sides need access
to all classes used by client and server, but that’s just a half
truth, right?

I’m needing to build a client class that just defines an API, then
allow clients to subclass it to customize it to their needs. The
server will be able to handle this as long as the client object is
DRbUnDumped or proxied, right?

I just want to make sure I’m not crazy, before I try to build it.
Thanks.

If you pass a proxied object rather than marshalling it, yes. The server
will be able to access the client object in the context of the client.

I’m using this fact now with great success:

In this model, the server uses the $stdin/$stdout/$stderr of the calling
client. Neat stuff.

Everyone is crazy. That shouldn’t stop you from trying.

Half truth. Access to all classes or appropriate use of
DRb::DRbUndumped.

Should work perfectly.
