Fix various golangci linter issues#977

@kevpar PTAL when you get the chance |
|
Any chance for a brief overview of what these are? e.g. are 90% of these "remove unused code"? |
|
The fact that our old linter complained about this PR made me giggle |
|
And that's why I didn't want to change linter in #970 but instead make it a separate step :)

curious; what was the linter complaining about here?

It complained because the call to StartSpan returns a new ctx, which isn't used again in the function.

Ah!
would something like this work for those as well?

Can we do _, span := ... and remove the nolint?

we can't add new functions on the context struct type since it's defined in a different imported package that we don't own.

If we keep the nolint directives in, and then later change the code such that they are no longer needed (e.g. start using ctx), will the linter tell us "hey, this directive isn't doing anything"?

Not from what I've seen

I don't have a strong preference here. I would probably go with _, span := ..., and rely on re-creating the ctx variable later if we end up needing it, but leaving the nolint directives in seems okay to me as well.

I think I'm going to keep the nolint directives in for now and if it becomes annoying we can take them out.

do you know why this was here? (or was this just copy/pasta from another block?)

Looks like that was something @jstarks wrote two years ago, so maybe he can comment haha
@katiewasnothere just wanted to make sure you saw this. |
@kevpar I updated the PR description with some info. Is there something else that I should add that would make it clearer? |

Why did we remove this assignment?

The linter was complaining because below we check if shimOpts is nil, so it didn't like this direct access to it. But also, we set it additionally right below this struct creation, so we only need one :D

looks like it was noticed just before / after merge 🙈 #915 (comment)

I thought I force pushed to fix before checking in 😭 😭 😭. Well I've gotta give it to myself, I both fixed it and then broke it again. This deserves a medal

💩 happens; you did that to test if the linters work, correct? 😂

100%, don't let anyone tell you otherwise 😉

This is obnoxious. Maybe we need to think about turning off the error check lint in the future.

I think it's valuable to have on. I think we should just find a better way to handle cases where we don't really care about the error. Maybe log a warning? Probably depends on the case though.

Fix various golangci linter issues
This PR fixes the various linter issues discovered in #975.
Many of the fixes involved adding a comment to exclude code from specific linters, see No Lint.
For warnings relating to deadcode, the related code was removed. Warnings that related to ineffectual value assignment for context variables, I excluded the line from the
ineffassignandstaticchecklinters. This was to help ensure future log statements that may be made in these functions use the correctctxvalue. For warnings relating to not checking the error code of a function call, I excluded theerrchecklinter for that line, since it was likely intentional to ignore the error. If this is not the case, we can fix the relevant areas.To see a list of the default checks made with golangci, see here.
