Warning about comparisons for indirect errors #55
Description
The following code produces no warnings (since v1.4.4, which has #10 fixed).
func CompareUnixErrors() {
if err := unix.Rmdir("somepath"); err != unix.ENOENT {
fmt.Println(err)
}
}but if we wrap unix.Rmdir into a function:
func rmdir(path string) error {
return unix.Rmdir(path)
}
func CompareUnixErrors() {
if err := rmdir("somepath"); err != unix.ENOENT {
fmt.Println(err)
}
}we still get the warning:
unexpected diagnostic: comparing with != will fail on wrapped errors. Use errors.Is to check for a specific error
