I am doing so during years (in C, not D) and
did not expierienced extremely complex troubles.
I mean I do not use libpq - instead I implement some
subset of the protocol, which is needed for particular program.
Very interesting. I need to stand-up this program and two others
in one week, so it looks like dpq2 and message passing is the
good short term solution to reduce implementation effort. But I
would like to return to your idea in a couple months so that I
can try a fiber based implementation instead.
Usually I design more or less complex (network) programs using
event-driven paradigm (reactor pattern) plus state machines.
In other words programs designed this way are, so to say,
hierarchical team of state machines, interacting with
each other as well as with outer world (signals,
timers, events from sockets etc)
It sounds like you might have a rigorous way of defining and
keeping track of your state machines. I could probably learn
quite a bit from reading your source code, or the source for
similarly implemented programs. Are there examples you would
recommend?
