Clients

Since clients are simply Proxy objects that receive a list of available functions when they first connect, they are PyroLab version-independent.

Note that it’s always a good idea to use proxies in a context-manager to clean up the connection:

with locate_ns(host="...") as ns:
    uri = ns.lookup("...")

with Proxy(uri) as remote_object:
    remote_object.useful_method()

Assuming drivers and services have been written correctly, they only raise builtin Python exceptions. You can also catch different levels of exceptions if you know what exceptions an object can raise. Therefore you can use them in try-except blocks:

try:
    remote_object.useful_method()
except ConnectionError as e:
    # handle this kind of error
except Exception as e:
    # handle the generic exception
