Description of change
The only tests for addMembership()
and dropMembership()
(from the
dgram
module) were in test/internet
which means they almost never
get run. This adds checks in test/parallel
.
Since I was doing the necessary git archaeology anyway, I took the time
to add YAML information to the docs about when addMembership()
and
dropMembership()
first appeared in their current forms.
I also did some minor tidying on the existing test/internet
test.
