Quick question: is the AWS_ACCESS_KEY_ID supposed to be visible? @Centril

mati865 · 2019-05-06T13:44:30Z

It might be not worth just now: #37939

hellow554 · 2019-05-06T13:52:12Z

@mati865 I'm sadly aware of that issue~~, but a quick test showed that since 1.32.0 they produce the same asm at least on godbolt~~

forget that, sorry :)

Quick question: is the AWS_ACCESS_KEY_ID supposed to be visible?

Yep, the access key id can be public. The actual sensitive part is AWS_SECRET_ACCESS_KEY which is not visible, and also not included in PR builds. We could make AWS_ACCESS_KEY_ID secret, but it would be annoying for us when we need to track down where a key is used.

Oh boy.. what happened here? AFAIk I haven't closed this PR.

Concern by @mati865

#37939 probably should be fixed first
