you will need to get hold of the remote exception class.
the easiest solution would be to have a local copy of the module defining
the exception (including it's packages).
if that's not possible, there are some options you can use:
1) catch rpyc.core.vinegar.GenericException, which is the base class of all
generated exceptions
2) look up your exception in rpyc.core.vinegar._generic_exceptions_cache by
name
3) put an exception into rpyc.core.vinegar._generic_exceptions_cache, e.g.
class MyServerException(Exception):
pass
rpyc.core.vinegar._generic_exceptions_cache["the.server.module.MyServerException"]
= MyServerException
i think (3) is best. you can also define a class decorator to hide the
gruesome details:
def vinegarify(remote_name):
def deco(cls):
rpyc.core.vinegar._generic_exceptions_cache[remote_name] = cls
return cls
return deco
@vinegarify
class MyServerException(Exception):
pass
it's quite a corner case, you usually don't expect to catch remote
exceptions that are not known on the local side...
but it's doable, as shown above.
note that i haven't tested the code, but it should work. if not, try to
tweak with it a little.
hope this helps,
