This is refactoring of the benchmark.
It contained millions or thousands which is changed to n

Fixes : #18778

Hm, it seems like the description in #18778 was not clear enough: it was not about just replacing the variable name. Instead of having millions = 1 it should be n = 1e6, not n = 1. That applies to all of these changes.

This also has influence on the for loops and the benchmark end call. These should be changed accordingly.

If there is a iter variable as here, it is likely obsolete and it could be replaced with n instead.

working on it.

BridgeAR · 2018-02-22T01:09:22Z

@juggernaut451 since you opened multiple pull requests so far: would you be so kind and please have another look at the commit guidelines?

juggernaut451 · 2018-02-22T06:15:16Z

@BridgeAR changed the commit message. Thank you for pointing out.

BridgeAR · 2018-02-22T13:54:11Z

@juggernaut451 So far nothing is changed. I guess you did not push your commit. If you want to change the commit message, you have to change the commit history by force pushing. Please use git push --force-with-lease.

juggernaut451 · 2018-02-22T16:38:20Z

@BridgeAR sorry forgot to push the message. Can you please check now?

benchmark/es/defaultparams-bench.js

I'd like to use 1e8 for consistency. (ditto throughout)

@starkwang so everywhere I should replace the value of n with 1e8?

I am not sure what the question stands for. Is there something unclear with the suggestion from @starkwang ?

@juggernaut451 100e6 means 100 * 1e6, 1e6 means 10^6. Thus 100e6 can be written as 1e8.

changes made. Thanks

Besides the comments there are a couple of tests that still need to be changed as well. The millions and thousands entries should be replaced in that case.

BridgeAR · 2018-02-24T15:12:33Z

benchmark/buffers/buffer-compare-instance-method.js

bench.end should never say n / x. Instead, it should always only be n. That applies to all benchmarks and is missing in many files here.

Mostly correct. There are cases where we see how many requests a server can take over 10 seconds and then we run bench.end(numberOfRequests) but those are special cases.

benchmark/timers/immediate.js

The comment from @starkwang applies here as well and in more places.

BridgeAR · 2018-02-27T09:02:35Z

benchmark/timers/immediate.js

This is a independent change and is not necessary. Please change it to the way it was before to reduce churn. This applies to all these functions in this test.

BridgeAR · 2018-02-27T09:11:21Z

benchmark/buffers/dataview-set.js

Renaming this variable is not necessary. I would rather change it to the way as it was before to reduce churn. That applies to all functions in this test besides main.

In this const len = millions * 1e6 was defined. There is no need of len as it's value is n. So that's why I replaced len with n. If I don't replace then I have to initialize the len

So what I meant is that only the main function is impacted by that change. You can keep the len argument here and only change len / 1e6 to len. That way there is less churn.

that sounds good. Thanks :)

changes made.

BridgeAR · 2018-02-27T09:14:59Z

benchmark/process/next-tick-breadth-args.js

Please do not use i but n here and only n and no division as mentioned in another comment. That applies to all cases in this test.

changes made :)

BridgeAR · 2018-02-27T09:15:20Z

benchmark/process/next-tick-breadth-args.js

Nit: please remove the line break here.

changes made :)

BridgeAR · 2018-02-27T09:16:01Z

benchmark/process/next-tick-depth-args.js

Please do not add double line breaks. This is a unnecessary change.

changes made :)

BridgeAR

This looks quite nice now.

AndreasMadsen

LGTM. Thanks, this is something that has annoyed me for a long time and confused new users, thus I'm very happy to see this is now fixed :)

Well done!

juggernaut451 · 2018-03-01T19:57:52Z

Thanks, @AndreasMadsen

apapirovski

LGTM but needs to be rebased and there's a small nit below.

apapirovski · 2018-03-04T14:24:55Z

benchmark/buffers/dataview-set.js

This could just use n throughout the main function rather than creating an extra variable.

It is done to reduce the churn as requested by @BridgeAR

No, I actually explicitly excluded the main function in my comment ;-)

making the change on the main function too

@juggernaut451 if you click on the CI link and scroll down to the bottom you'll see a link to node-test-commit:

If you click on that link you'll see that it failed, so you need to go to the Console Output on the right:

If you click that you'll see this:

I know that this PR isn't showing that there are conflicts, but the CI does the rebase in a different way.

I'm pretty sure this commit is the issue:

Basically what you need to do is to squash all your commits into one commit, and then rebase that on top of the upstream master branch.

Thank you @gibfahn

@starkwang can you please re run the CI

richardlau · 2018-03-28T09:11:00Z

CI is currently locked down for the security release: #19642

"thousands" is misspelled in the commit message.

ChALkeR · 2018-03-28T10:04:07Z

Perhaps var should be changed to let in the touched lines?
That works down to 6.x and I don't think this is going to be backported to 4.x.

BridgeAR · 2018-04-09T10:42:02Z

New CI https://ci.nodejs.org/job/node-test-pull-request/14134/

@ChALkeR there are only very few lines that touch var in this PR. So I believe we should go ahead and land this instead of delaying it further for that.
