[Orbit-python-list] doing a frontend/backend with o-p

[Adam O. <rh...@d2...>]

The situation:  I want a frontend that checks for user input, a
backend that checks networking, and for them to notify eachother when
they get input.

The problem:  If they both try to notify eachother at once they'll
deadlock.  It's a race condition.

The solutions:
a) I can make the frontend poll the backend for updates, instead of
the backend pushing them to the client
b) I can make them able to service requests while making requests of
their own.

b can be done either by making the orb reentrant[0], so that it
recursively handles requests when waiting for requests of it's own to
be answered, or by using threads.  If there's a problem with threads
then forking could probably be done instead.

And so my question:  what is the practical solution now, and what'll
be practical in the future?
