Description
Since the version v1.45.0 golangci-lint supports go1.18.
But some linters don't work with generics, golangci-lint disable those linters automatically with go1.18.
Since v1.45.1, golangci-lint can detect the Go version used by a project.
To get the Go version golangci-lint will use, in order:
- the Go version defined by the CLI flag, ex:
--go=1.18 - the Go version defined in the configuration file, ex:
run: go: '1.18'
- the Go version defined in the
go.mod, ex;module github.com/org/my-project go 1.18
- Go version defined by the env var
GOVERSION - fallback on go1.17.
Notes:
- some rules in go-critic (
externalErrorReassign) don't work with generics and must be disabled by hand - if you are not using generics (and your dependencies) you can use the following configuration:
run: go: '1.17'
The keyword any works well and produces no error (it's expected because it's just a type alias)
The problem with SSA is now fixed but some linters need to update their code base to handle generics.
About the linters:
- for
go-critic, there is an existing issue Support generics for Go 1.18 go-critic/go-critic#1193
Linter issues: (checked if the problems are solved)
- govet(nilness,unusedwrite)
- staticcheck, stylecheck, gosimple, unused
- bodyclose
- contextcheck
- nilerr
- noctx
- rowserrcheck
- sqlclosecheck
- tparallel
- wastedassign
- unparam
-
struccheck: Deprecated - go-critic(externalErrorReassign)
The binary compiled with go1.17 doesn't work when running on go1.18:
$ golangci-lint run
panic: load embedded ruleguard rules: rules/rules.go:13: can't load fmt
goroutine 1 [running]:
github.com/go-critic/go-critic/checkers.init.22()
github.com/go-critic/[email protected]/checkers/embedded_rules.go:46 +0x4b4
Compatibility table
🟢️: means that the linter seems to work, but it's not 100% sure, it needs to be tested on more go1.18 code.
🟠: means that the linter works partially.
🔴: means that the linter panic.
