YANG Versioning Weekly Call Minutes - 2022-05-24
As part of "per-element" BC/NBC tags, we need to define default assumptions
that a tool will make for certain types of module changes. Note that these are
just assumptions, not definitive rules that these changes are indeed NBC or BC.
In some cases, there will be a default assumption below, but an author is
obligated to document whether a change is BC or NBC (e.g. for a "must"
statement the tool will assume NBC, but the author will decide if it is really
BC or NBC, and potentially tag that element, based on whether the constraint is
relaxes or not, as per RFC 7950).
A) descriptive strings (e.g. description, org, presence argument string,
revision, units): editorial (for add/remove/change)
B) changes that a machine should be able to compare and easily determine BC vs
NBC (e.g. YANG version, range, import, adding a "must", etc): as per rules in
draft
C) changes that are complex/unrealistic for a machine to figure out (e.g.
changes to patterns, must statements, when statements, and leafref paths): NBC
D) extensions: if it is a known extension to the tool then use the defined
rules for that extensino. If unknown, then assume BC but flag "unknown
extension additions / removals / changes". Note:
- some models are sprinkled with BC extensions
- some models are sprinkled with NBC extensions
Balazs: New github issue: codify how extension additions/removals/changes are
BC vs NBC in a machine readable way
[ maybe in tool comparison draft ?]
Jason: New github issue: did we forget to say that import changes are BC in
module versioning ? (adding, removing, changing the import by revision, etc).
Add to section 3.1.1.
We're now done going through the feedback on WGLC from Jurgen, Italo and Andy.
Responses are in progress by Reshad, Rob and Joe.
Next meeting: talk about Comparison Draft and Packages
