YANG Versioning Weekly Call Minutes - 2021-01-05
(see the link below to join the calls)
Key topics & next steps for the versioning work:
A) drafts expiring (reqs, versioning, semver)
-> bump requirements draft
-> let versioning and semver expire until real updates or IETF 110
B) open issues review (yang versioning first)
-> we left off at issue #15 https://github.com/netmod-wg/yang-ver-dt/issues/15
C) next virtual interim (who preparing what?)
-> Balazs for config false rules
D) ORAN/3GPP liaison statement
E) Whitespace issue
Add new topic to Feb virtual interim:
## new: 0) Definition/meaning of BC vs NBC for config false nodes
Move the Semver "gaps in history" issue as the first Semver issue for the Feb virtual interim
BC vs NBC for config false nodes:
- review expectations of clients (e.g. handle unknown tags, handle values outside the 'range' statement)
- no validation on outgoing data today in 7950. Is that an indication that there are no guarantees on config false nodes?
- changing type should be NBC for config true or false nodes (**including changing something to a union that is a superset of the previous type? -> yes, receiver may suddenly get that new member)
- reverse the meaning of some rules (expanding vs shrinking value spaces), but look at 3.3
- adding mandatory: different rule for config true vs false?
- suggested approach: go through 7950 rules and try to stick with them as much as we can for config false, but define/highlight rules that should be different for config false
[Balazs to take a first stab at the rules]
