test: fix setTimeout, remove unused err #10193

amazingandyyy · 2016-12-09T08:11:27Z

file: test/parallel/test-domain-uncaught-exception.js

There are three setTimeout() in the file and they do not specify a
duration (the second argument), so I change them to setImmediate()
instead.

There are four callbacks that take an argument called err but that
argument is never used, I just removed them.

The test used to test that exceptions thrown from setTimeout were in the domain, now they test that test thrown from setImmediate are still in the domain! I don't think you are looking at what the test is doing.

I understand your point. Since it does not specify a duration (the second argument), I think it's more appropriate to change this call to setImmediate() instead of setTimeout().

For this test, instead of changing the setTimeout() to setImmediate(), it is better to keep setTimeout() but add a duration of 1. @sam-github is right. This is testing a timer, not an immediate. Changing it to an immediate changes the test. In other words, the setTimeout() is not an incidental tool used within the test. It is part of what is actually being tested.

(In @amazingandyyy's defense, I'm the one that suggested changing setTimeout() with no duration to setImmediate() in the first place. But yeah, that's not right in this test.)

  });

  d5.run(function() {
    d6.run(function() {
-      setTimeout(function onTimeout() {
+      setImmediate(function onSetImmediate() {


ditto. the point of the test isn't to run these functions, its to test interactions with timeouts and domains

same here, it does not specify a duration (the second argument), setImmediate is more appropriate.

@sam-github is (as usual) right on this one too. We're testing that domains and setTimeout() interact the way they are supposed to, so it needs to be setTimeout(). Add a duration of 1 rather than changing it to setImmediate().

sam-github

This looks to me like a combination of random code churn, and unintended changes to the function of the tests.

Trott · 2016-12-09T23:58:20Z

I don't think the changes to test-domain-timers.js belong here. Can we please limit the scope of this PR to just test-domain-uncaught-exception.js?

Trott · 2016-12-10T00:01:28Z

test/parallel/test-domain-uncaught-exception.js

    process.send('errorHandledByDomain');
  });

  d9.run(function() {
    d10.run(function() {
-      setTimeout(function onTimeout() {
+      setImmediate(function onSetImmediate() {


Same here: Use setTimeout() with a duration of 1 instead of setImmediate().

Commits need to be squashed

addaleax

LGTM

Squashing commits can also be done by whoever lands the PR, btw.

sam-github · 2016-12-13T19:30:54Z

@addaleax, it can, but last time I did that @mhdawson suggested I ask the PR author. Rebasing is part of the work flow, so knowing how to do that helps get people up to speed with node work habits. On the other hand, doing it for them makes it easier. I don't care.

@amazingandyyy do you want to squash, or do you want me to?

addaleax · 2016-12-13T21:28:16Z

@sam-github Right, but squashing and rebasing can be tricky depending on somebody’s git experience level, so I like to mention that it’s optional.

amazingandyyy · 2016-12-13T22:06:28Z

@sam-github @addaleax I just do "git rebase -i HEAD~6" and then replace "pick" by "squash" then save the file.

I am not sure if this works? I still see 6 commits on this PR. I appreciate this practicing chance.

btw, Please feel free to squash it(if my rebasing doesn't work) when landing, thanks!

italoacasas · 2016-12-13T22:09:10Z

@amarzavery the last step is to comment all the msg except one (the one that you are going to use as a commit msg)

addaleax · 2016-12-13T22:09:29Z

@amazingandyyy That sounds about right, except you’ll need to keep the first commit as pick

file: test/parallel/test-domain-uncaught-exception.js 1. There are three setTimeout() in the file and they do not specify a duration (the second argument), so I change them to setImmediate() instead. 2. There are four callbacks that take an argument called `err` but that argument is never used, so I removed them.

amazingandyyy · 2016-12-13T22:32:32Z

Thank you! @italoacasas and @addaleax

I leave one as pick and clean commit message, then got

amazingandyyy ~/projects/node $ git rebase -i HEAD~6

but I still see 6 commits on this PR, do I miss any step or what's next step to complete(make the squashing work?) Thanks

@amazingandyyy just noticed that the commit message does not fit our contributor guidelines. I'll fix up as part of landing but can you review the guidelines for the next time.

The commit message should start with a prefix. In this case 'test:' and the length needs to be less than or equal to 50 chars. See https://github.com/nodejs/node/blob/master/CONTRIBUTING.md#step-3-commit

mhdawson · 2016-12-14T18:28:45Z

CI failure on arm was #10073, so not related to this change so CI is good. Will land.

We do not need anyone's name for commits. It is up to them.

(Always good to ask first-time contributors, though, of course! People forget to set the name all the time. So, it's a nice gesture to make sure they are making a conscious choice in the matter. I'm just reacting to the "need your full name" phrasing. If someone wants to be "Pat" or "avatar-46", that's their choice.)
