Our documentation states that we support
.conf
and.json
config formats (which are the same, actually), but in reality only.conflist
works properly. All of them are fingerprinted correctly, but only conflist works at allocation run time.Fixes #19816
The first commit is here for a reference, which used a boolean to keep track of whether or not
confIsList
, but in my second pass I made a little struct to make it easier (I think) to hold correctly.I have some e2e tests set up for this too, but I'll do that in a separate PR since we generally don't backport those.
