// Ruleguard file implementing custom linting rules.
|
|
//
|
|
// Note that when used from golangci-lint (using the gocritic linter configured
|
|
// with the ruleguard check), because rule files are not handled by
|
|
// golangci-lint itself, changes will not invalidate the golangci-lint cache,
|
|
// and you must manually clean to cache (golangci-lint cache clean) for them to
|
|
// be considered, as explained here:
|
|
// https://www.quasilyte.dev/blog/post/ruleguard/#using-from-the-golangci-lint
|
|
//
|
|
// Note that this file is ignored from build with a build constraint, but using
|
|
// a different than "ignore" to avoid go mod tidy making dsl an indirect
|
|
// dependency, as explained here:
|
|
// https://github.com/quasilyte/go-ruleguard?tab=readme-ov-file#troubleshooting

// Suggest rewriting "log.(Print|Fatal|Panic)(f|ln)?" to
|
|
// "fs.(Printf|Fatalf|Panicf)", and do it if running golangci-lint with
|
|
// argument --fix. The suggestion wraps a single non-string single argument or
|
|
// variadic arguments in fmt.Sprint to be compatible with format string
|
|
// argument of fs functions.
|
|
//
|
|
// Caveats:
|
|
// - After applying the suggestions, imports may have to be fixed manually,
|
|
// removing unused "log", adding "github.com/rclone/rclone/fs" and "fmt",
|
|
// and if there was a variable named "fs" or "fmt" in the scope the name
|
|
// clash must be fixed.
|
|
// - Suggested code is incorrect when within fs package itself, due to the
|
|
// "fs."" prefix. Could handle it using condition
|
|
// ".Where(m.File().PkgPath.Matches(`github.com/rclone/rclone/fs`))"
|
|
// but not sure how to avoid duplicating all checks with and without this
|
|
// condition so haven't bothered yet.
