test: convert var->const/let in tests #10685

gibfahn · 2017-01-08T14:59:24Z

Overview

Use eslint to convert all var to const/let in test/, manually fix anything that eslint messed up.

If we're going to go ES6 in test/, we might as well go all the way.

To fix rules with eslint

Apply this:

diff --git a/.eslintrc b/.eslintrc
index cf1f36c86b..e09fd6ac64 100644
--- a/.eslintrc
+++ b/.eslintrc

cc/ @silverwind @Trott @not-an-aardvark Is there an easy way to make rules only apply to test/? Also should @not-an-aardvark be on the tools/eslint cc list in onboarding-extras?

Is there an easy way to make rules only apply to test/

Add the rule to test/.eslintrc.

gibfahn · 2017-01-08T15:25:19Z

@targos

Add the rule to test/.eslintrc.

Thanks, done

Rubber stamp LGTM if the CI passes.

gibfahn · 2017-01-08T22:29:14Z

CI: https://ci.nodejs.org/job/node-test-commit/7103/

EDIT: CI passed

gibfahn · 2017-01-08T23:03:51Z

It's probably worth checking the second and third commits:

second (manual fixups of eslint issues): 27d10c0
third (require let/const in test/): 21725bf

Rubber-stamp LGTM

test/.eslintrc

Should these be:

no-var: 2 prefer-const: 2

? I'm not sure what the 2 represents here.

2 means error

Changed error to 2 for consistency.

I think you can const this one.

➜ node git:(var2const) tools/test.py test/parallel/test-http-get-pipeline-problem.js === release test-http-get-pipeline-problem === Path: parallel/test-http-get-pipeline-problem image.length = 45658 /Users/gib/wrk/com/node/test/parallel/test-http-get-pipeline-problem.js:38 for (const i = 0; i < total; i++) { ^ TypeError: Assignment to constant variable.

If this is what you meant, I don't think so. I can do for (let i = 0; though.

Weird, I could swear const loop variables once worked, but I see it's failing now. Your let suggestion sounds good.

test/parallel/test-http-many-ended-pipelines.js

unneccesary wrapping?

The semicolon puts it over 80 chars 😭

silverwind · 2017-01-10T22:54:27Z

test/parallel/test-http-url.parse-auth-with-header-in-request.js

unneccesary wrapping?

81 chars again

Move the string to a variable so it doesn't look so hideous? :)

silverwind · 2017-01-10T22:56:18Z

test/parallel/test-writeuint.js

Same here, can probably use const.

Changed to let as above (const didn't work)

silverwind · 2017-01-10T22:56:37Z

test/parallel/test-zlib.js

const again.

silverwind · 2017-01-10T22:56:57Z

test/pummel/test-net-connect-econnrefused.js

const here too.

const doesn't work (the pending++ would be modifying it)

Actually, as is the test failed (it's not run in CI), to fix I had to move the let to the previous line.

silverwind · 2017-01-10T22:58:27Z

test/.eslintrc

Maybe alphabetically sort the rules?

gibfahn · 2017-01-10T23:15:19Z

@silverwind Updated, PTAL

gibfahn · 2017-01-10T23:16:43Z

Actually, I just realised that the eslint rule isn't showing up all the vars for some reason, I'll investigate later.

This will need backport PRs in order to land on v6 or v4

bnoordhuis · 2017-03-09T06:59:31Z

This is likely preventing a lot of pull requests from back-porting cleanly so I think it should be back-ported with some urgency. Likewise for #10698.

gibfahn · 2017-03-09T16:39:03Z

v4.x backport: #10685

MylesBorins · 2017-03-09T17:25:38Z

@gibfahn did can you do a v6.x backport too?

gibfahn · 2017-03-09T17:50:27Z

@MylesBorins I'll do it once I get the v4.x backport working. There's more pig-wrestling than I'd expected.
