Can you leave a todo comment to do proper exception handling in this method?

There is no exception handling in cares_wrap.cc. If this was needed, it would have been added for all parsing the other record types, too. I don't see a todo here.

There is no exception handling in cares_wrap.cc.

Right, it’s missing, so it would be nice to have a comment about that somewhere in the file

FWIW, this pulls c-ares patch that is not yet released which will break Node on systems where c-ares is linked as an external dependency. For this reason, I think this should not be backported to currently released versions.

AdamMajer · 2020-10-22T11:57:52Z

The don't-land-on-v15.x actually already happened. It's in 15.0.0+ in 6f34498

aduh95 · 2020-10-22T12:23:19Z

Indeed! Do you think that should be reverted on v15 or do you think it's fine as is?

AdamMajer · 2020-10-22T16:33:20Z

For me it's OK since we will not be shipping 15 with anything and by the time 16 rolls around we can either patch our c-ares for the extra functionality or have a new c-ares version by then.

Trott · 2020-11-04T19:41:54Z

Unfortunately, this broke a test in test/internet (which only get run nightly and I only got around to bisecting today):

node:internal/process/promises:218
          triggerUncaughtException(err, true /* fromPromise */);
          ^

AssertionError [ERR_ASSERTION]: The expression evaluated to a falsy value:

  assert.ok(Array.isArray(result[0]))

    at validateResult (/Users/trott/io.js/test/internet/test-dns.js:404:12)
    at test_resolveCaa (/Users/trott/io.js/test/internet/test-dns.js:411:3) {
  generatedMessage: true,
  code: 'ERR_ASSERTION',
  actual: false,
  expected: true,
  operator: '=='
}

Bug in the test? Bug in this change? Something else?

Trott · 2020-11-04T19:53:02Z

Oh, interesting, the test that is failing was added in this PR.

Is the bug that it should be checking Array.isArray(result) and not Array.isArray(result[0])?

Yeah, looking at the surrounding code, that's gotta be it.

@AdamMajer , @aduh95 : c-ares 0.17.1 has been released recently. It there any change to get this into v10, v12, or v14?

AdamMajer · 2020-11-20T16:49:32Z

I think no problem here to backport this to older versions now.

@AdamMajer , @aduh95 : c-ares 0.17.1 has been released recently. It there any change to get this into v10, v12, or v14?

10.x is in maintenance so this won't land there. The last planned 12.x release before it enters maintenance at the end of the month is due on Tuesday (#35950 ) so the chance of getting this into 12.x is low.

For 14.x the path forwards should be to update c-ares in master to 0.17.1 and then backport that together with this PR to 14.x.

I've created a pull request for c-ares 1.17.1 here: #36207

@richardlau c-ares 1.17.1 has landed in 3bd9b81, any other obstacles to backport this to 14.x?

For 14.x the path forwards should be to update c-ares in master to 0.17.1 and then backport that together with this PR to 14.x.

@richardlau c-ares 1.17.1 has landed in 3bd9b81, any other obstacles to backport this to 14.x?

Our general policy is that for LTS release lines (e.g. 14.x) a change should live on the current release (i.e. 15.x) for two weeks before being backported (https://github.com/nodejs/Release#lts-staging-branches). 3bd9b81 hasn't gone out in 15.x yet (the next 15.x release is planned for this week, nodejs/Release#621). The next 14.x release is going to be a security release (https://nodejs.org/en/blog/vulnerability/january-2021-security-releases/) so any backports of features would have to wait until after that. We haven't firmly sketched out the release plan for 14.x for next year, but have discussed planning a semver-minor for mid to late January.

So timeline wise:

3bd9b81 goes out in a 15.x release.
Two weeks after the 15.x release the c-ares update lands on v14.x-staging.
This PR is backported, minus the c-ares floating patch (as the intention is to use the proper c-ares update) and including test: fix error in test/internet/test-dns.js #35969 (fixing up one of the testcases). I've added a backport-requested-v14.x label.
