net/http: remoteEmptyPort could be optimized #76651
Description
Line 115 in f22d37d
func removeEmptyPort(host string) string {
if hasPort(host) {
return strings.TrimSuffix(host, ":")
}
return host
}
can be optimized to:
func removeEmptyPort(host string) string {
if len(host) > 0 && host[len(host)-1] == ':' {
return host[:len(host)-1]
}
return host
}
or using strings.HasSuffix:
func removeEmptyPort(host string) string {
if hasPort(host) && strings.HasSuffix(host, ":") {
return strings.TrimSuffix(host, ":")
}
return host
}
