Raw map configuration and case sensitivity

[pmalek]

Welcome

• Yes, I'm using a binary release within 2 latest major releases. Only such installations are supported.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've included all information below (version, config, etc).
• Yes, I've tried with the standalone linter if available. (https://golangci-lint.run/usage/linters/)

Description of the problem

It seems that golangci-lint (starting with v1.50?) passes the arguments to linters in lower case and not "as is".

This causes in our cases panic in revive

panic: Invalid argument to the context-as-argument rule. Unrecognized key allowtypesbefore

which can be tracked down to: https://github.com/mgechev/revive/blob/v1.2.4/rule/context-as-argument.go#L82-L110.

The same config with the same code base works fine with v1.49

Hey, thank you for opening your first Issue ! 🙂 If you would like to contribute we have a guide for contributors.

Hello,

[x] Yes, I've tried with the standalone linter if available

As you have checked this, can you give me the output of the revive command line?

Sure,

revive -config revive.toml ./...

With the following config:

[rule.context-as-argument]
  arguments = [{allowTypesBefore = "*testing.T"}]

It's related to github.com/spf13/viper@v1.13.0 (#3205)

spf13/viper#1387

So it's a breaking change inside Viper introduced by a bug fix, the new behavior will not change because it's the expected behavior from the Viper point of view, but it's a major problem for us.

spf13/viper#1431

EDIT: I reverted the update of Viper #3284 (golangci-lint v1.50.1)
