removes ioutil usage everywhere which was deprecated in go1.16 #15297

kschoche · 2022-11-08T21:25:49Z

Description

This is a cleanup PR that I'm testing, it would be sweet if it passed all the unit tests :-D

Deprecated: As of Go 1.16, the same functionality is now provided by package io or package os, and those implementations should be preferred in new code. See the specific function documentation for details.
https://pkg.go.dev/io/ioutil

This PR also introduces a new rules to the golangci-lint tool which forbids the use of the ioutil package and will result in output like this:

demo $ make lint
--> Running golangci-lint
command/logout/logout_test.go:34:12: use of `ioutil.ReadFile` forbidden because "Use io and os packages instead of ioutil" (forbidigo)
        _, err := ioutil.ReadFile("abcd")
                  ^
make: *** [lint] Error 1

PR Checklist

updated test coverage
external facing docs updated
not a security concern

@dhiaayachi I'm not sure if this one's been proposed before, but thought I'd see if there was any interest in this PR. Thoughts?

Thank you for working on this @kschoche!
Seems like your experiment is working 🚀
I added a comment about a commented code that I think we should remove.

I also have a suggestion to avoid regression for this (as long as ioutils is existing in golang). Maybe we can use something like this https://github.com/le0tk0k/noioutil to vet the code in the CI but feel free to merge this as is and have this in a subsequent PR.

You might be able to use the forbidigo golanglint-ci configuration to prohibit calls: https://github.com/hashicorp/consul/blob/main/.golangci.yml#L85

Ahh this is a great find, thanks!

Many times this sort of fixup doesn't necessitate a changelog entry. Your call if you think we should have one.

Makes sense! I was on the fence about it, so I'll remove it then, I think the commit message should be good enough!

Usually we handle go version compatibility differently in the api package so that folks using the library aren't forced to upgrade to a future version before they're ready. I think the policy seems to be assuming folks are using a go version that is still receiving security updates (which 1.16 is definitely NOT anymore).

So in this case it's fine to do the swap. I wonder if we should correlate this with bumping the go directive in api/go.mod from 1.12 to at least 1.16 or maybe all the way to 1.18 (which is the oldest version we test against in CI).

The same logic would apply to sdk/go.mod too.

👍🏽 Can do, I think 1.18 makes sense here then.
There is a ton of module tidying, save that for another PR?
