Ongoing device development in alpha

[zack-vii]

I already mentioned this in our meeting some time back. We should move the device driver development outof our release branches. these atomic merge/release of unfinished device drivers has side effects on what you can do to improve your driver code.

#2284 should not be ok according to our backwards compatibility rule as it breaks the device node structure, existing trees will not work anymore.

If you dont expect anyone to use your device, why releasing it with mdsplus. If you just do it for an easy distibution on your test site, this is bad practise.

Furthermore we now have them released in stable as well, so we have two versions of the same driver.

I strongly suggest moving the device drivers out of our releases.

Hi Timo,    even if I agree with you on moving device development stuff outside main MDSplus branch (we should agree however on how doing it, in order to avoid using each a different approach, I would see it as another mdsplus project in github, as done for example in MARTe2-MDSplus project ), I would like to remind that there is a quick way for backward compatibility in devices in case some node are removed/added that we use routinely, that is to Decompile and Compile again the tree, i.e. DecompileTree <my_tree> CompileTree <my_tree> CompileTree will create new devices instances with the latest version and copy the content of other nodes accordingly. Of course this wont work is the semantics of some node has changed, must in the vast majority of the cases, new nodes are added without affecting the semantics of the others. Gabriele
