OSNews, Generic OSes It's funny how trying to have a consistent system design makes you constantly jump from one area of the designed OS to another. I initially just tried to implement interrupt handling, and now I'm cleaning up the design of an RPC-based daemon model, which will be used to implement interrupt handlers, along with most other system services. Anyway, now that I get to something I'm personally satisfied with, I wanted to ask everyone who's interested to check that design and tell me if anything in it sounds like a bad idea to them in the short or long run. That's because this is a core part of this OS' design, and I'm really not interested in core design mistakes emerging in a few years if I can fix them now. Many thanks in advance.

In RPC, you assume that the remote end has a procedure you can call. That's a big assumption. To make it work, you assume that the remote procedure is written in the same programming language. That's a huge implementation "detail".

Remote objects are just an object oriented extension of the RPC concept. They were en vogue in the nineties, when everybody switched to remote architectures. This was when CORBA and other such methods were found to be too cumbersome.

Messaging has a long history, really. These lessons were already learned in AmigaOS, BeOS, Syllable and new messaging systems such as 0MQ. You can also ask yourself what the most successful remote protocol does. Is HTTP/HTML RPC based?
