[faddat]

let's do it. codecov is unhelpful anyhow.

[melekes]

Is it possible to exclude Pebble from this PR and make it only about lint changes?

[melekes]

#112 needs to be merged first.

[faddat]

@melekes yes, I agree.

[melekes]

do you mind bringing this back?

[faddat]

Few minutes.

[faddat]

generally, depguard isn't in my lint religion -- did you want it back & configured?

[melekes]

./pebble.go:60:107: too many arguments in call to registerDBCreator
	have (BackendType, func(name string, dir string) (DB, error), bool)
	want (BackendType, dbCreator)

looks like I broke something. sorry about that

[faddat]

Oh that's okay I'll fix it

[faddat]

I'll add a make test-pebble to default test runs..

[melekes]

please remove
