Oops! Sounds like you need to rethink your sequential design!
:The summary we arrived at last time was that by default user commands
:should be executed strictly sequentially. This was to be done via
:sequence number dependancies. However, we also saw a use in commands
:which were to be explicity executed in parrallel with other user
:commands. One of the primary uses for such was an interrupt command
:which more or less said, "kill the entire command queue NOW!".
That, and prioritized interuption...
:(Hey Jon! This is another thread to add your list of things to dig up
:-- the one about command sequencing, priority commands, command
:interrupts, and job control for asynchronous command execution. It
:was mainly between CG and myself.).
And I may go and fish out a bunch of the stuff I wrote on the subject in
the rgm.diku "Event-based vs Loop-based" thread several months back...
:>I'd say that an input
:>command from a user cannot even be ready for execution until all
:>previous commands from that user have C&C'd.
:In the general case yes. An explicit exception should be made for
:interrupt commands.
I don't like it even in general. Of course, my model is different, and not
very many commands are executed as a single event, which is a major part
of the rational behind the "event chain" model (I once provided a martial
arts example, in which a jump kick is transformed into a somersault and
turn when the target dives out of the way...)
:>Haven't we talked about just this
:>before?
:Yup. However our new members didn't catch that thread.
We've got a lot of threads could use a dustin off, I reckon.
