One more important point. In R3.14 we took the important step of moving all of the OS
interface layers into a common area in libCom. In contrast, in
the past I maintained some of them in with the CA client library because the CA client library was the only
part of base that was portable at that time. The consolidated approach makes porting EPICS to a
new OS easier. Michael has in his published version of EPICS placed his derived
version of my source code into libCom. His derived code now
occupies exactly the same niche in libCom that my original
version does in the decapitated CVS trunk. Note that the Michael’s derived version neither currently works
correctly nor makes any attempt to conform to the interface that my work in the
decapitated CVS trunk requires. Some people may ask this question; what is the problem with what
Michael has done, he can maintain his version and Jeff can maintain his version and
we can all be happy. The problem with that approach is that porting EPICS is now harder
because I would be forced to maintain private copies of at least some of the OS
interface layers in CA. Something that I am definitely not in favor of doing. Sorry about the interruption, Jeff Message

[mailto:[email protected]] On Behalf Of Jeff Hill Ø I'll contact my legal department today I hope
that you find this to be constructive. This is a relatively small piece of code, and with enough effort
it is always possible to take the concepts and write a completely new code (it really
helps to have the original ideas and the original source code to look at). Maybe it’s even
strictly legal to take the low road. I think the wider issue is this; we get to choose, we can work
together or duplicate effort creating functionally
equivalent codes. Hence my feeling compelled to consume some bandwidth to discuss the issue on tech-talk. Jeff Message
