mod_firewall: Initialize compiled chunk just once for all handlers This should fix a case where some stateful dependencies (such as throttles) produce separate instances for every call to new_handler(), leading to surprising behaviour (e.g. rules executed via JUMP CHAIN vs ::deliver would have separate rate limits). This also adds better error handling in case the compiled code fails to run for some reason.

package main

import "fmt"
import "bufio"
import "os"
import "strings"

const (
	ACTION = iota
	USER
	HOST
	PASSWORD
)

func main() {
	stdin := bufio.NewScanner(os.Stdin)
	for stdin.Scan() {
		parts := strings.SplitN(stdin.Text(), ":", 4)
		switch parts[ACTION] {
			case "auth":
				if parts[USER] == "someone" {
					fmt.Printf("1\n")
					continue
				}
				
			default: fmt.Printf("0\n")
		}
	}
