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.

These should likely be done as a separate commit

Couple of minor nits. Otherwise LGTM if CI is green.

test/parallel/test-dgram-membership.js

+const common = require('../common');
+const assert = require('assert');
+const dgram = require('dgram');
+const multicastAddress = '224.0.0.114';


Is this something that could be moved to common?

I'm on the fence on that. I have a concern that putting that address in common will signal to people (like me) who don't fully understand multicast that it's OK for tests in parallel and sequential to communicate with that address. It's not, I don't think, and that's probably why the existing test that uses that address is in internet.

This test needs to have an address to test addMembership() and dropMembership(), which, now that I think about it, I guess means that this test will cause some IGMP traffic on the local network?

/cc @nodejs/build in the hopes someone who actually understands how multicast works can say "Yup, this test will send a packet" or "Nope, this test does not send a packet on the network."

Hmmm, although 224.0.0.114 would be multicast on the local subnet only, so maybe it's OK in the context of this test? Like, it's not sending packets destined for the Internet or anything...

I can't say for sure it's true for all platforms but just joining or leaving a local multicast group (which all 224.0.0.xxx addresses are) should not generate any traffic, that's just bookkeeping to the kernel.

LGTM with a comment. I also second @jasnell's nits.

Trott · 2016-05-16T22:15:15Z

Per nits from @jasnell and @cjihrig:

Moved doc metadata update into its own commit
Omitted removal of lib/dgram.js comment

LGTM, thank you

Missing socket.close()?

@bnoordhuis Yes, good catch. Added socket.close(), rebased against current master, force pushed.

Trott · 2016-05-18T05:10:52Z

Rebased against master, fixed a nit from @bnoordhuis, time to run CI again: https://ci.nodejs.org/job/node-test-pull-request/2685/

parallel/test-dgram-membership and the documentation changes LGTM but the style fixes to the other test don't really belong, IMO.

Lots of failures on one of the smartos machines although I don't think they're related to this PR. The test itself passes: https://ci.nodejs.org/job/node-test-commit-smartos/2537/nodes=smartos14-64/console

True. I'll remove those style changes and re-run CI. If no surprises, landing soon...

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.

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`. I also did some minor tidying on the existing `test/internet` test.
