Re: [netmod] Obsolete feature - what does it mean?

[Balázs Lengyel <[e-mail]>]

feature oldFeature {
  status obsolete;
}

leaf myTimer {
  if-feature oldFeature ;
  mandatory true;
  config true;
  status current;
  type string;
}

So should I configure myTimer or not? I assume yes, correct?

regards Balazs

   Hello,

   The feature statement may have a status substatement. But what does it
   mean if a feature is deprecated or obsolete? Some ideas:

     * All if-feature statements using it should be removed. But what to do
       with "if-feature oldFeature AND otherFeature" ;
     * The feature is always considered true/false
     * this is a bug in rfc7950, there should not be such a substatement
     * something else

Deprecated means the feature is deprecated, you should not use it in
new definitions. A feature is not "true or false", a feature can be
implemented or not. A current definition being conditional on a
deprecated feature may be something tools should warn about.

Obsolete means the feature is obsolete, it likely should only be used
in obsolete definitions. A current definition likely should not depend
on an obsolete feature and if that happens, then likely brainware
needs to look at the situation and resolve it.
