You can apologize for the rough tone all you want, but I find this attitude towards documentation appaling. That's not to say I think the documentation should be widely availiable--in fact, I think it should not be for the exact reasons you specify. However, knowing that there is one and only one guru who knows what's going on scares the begeezes out of me. As someone who implements Epics based systems--primarily with the PCAS, but with iocCore as well, I find it disconcerting every time a problem is posted to this list. The first few responses--if any--are from well meaning, knowledgable, experienced users offering what amounts to an educated guess--it can't be much more than that because the internals of CA are unknown. Then, perhaps a week later, the guru responds with the only answer I find I can trust. I know Jeff is busy and I'm not saying he has to offer 24-7 tech support, but knowing he is the only guy who understands the CA protocol--the hing-pin of EPICS--makes me wonder what shape the community would be in were, God forbid, something to happen to him. Is that the point where Epics ceases to exist? Does someone step in to do their best only to have the "official" Epics CA libraries become buggy due to lack of knowledge/experience? Do we then get an open protocol where people who need to can muck about? Again, I'm not saying the protocol specification needs to be generally distributed, but I would sleep better at night if I knew it were written down somewhere and there was at least one other individual spending some amount of time developing with it. Sorry for my tone, but I manage several projects on which I am the only person who knows how they work. I've fought for years to try and get someone else involved to understand them in case I leave. Having failed that, I have at least documented my efforts to the best of my ability such that someone else might have a fighting chance to take over after me--it's the only responsible thing to do.
