Code:
[13:06] No longer banning *!*@exezic.users.quakenet.org on #dota.no (expired)


Is there any way to detect when this happens?

My intension is to make a web-based banlist, and I therefore need it to be updated whenever a dynamic ban expires.

I am aware of the possibility of using a timer to check a list up against the current banlist. But I would prefer to just update the list whenever it is changed, instead of having a timer running in the background all the time.

I appreciate all and any responses.

No. (you'd have to keep a copy of the list and compare it to the internal one to do that...but then you might as well create the html all over again)

If you have a botnet, you can bind to the botnet message.

Oh, and if you can compile your bot yourself, you can also consider to call something in src/mod/irc.mod/irc.c function check_expired_chanstuff() which seems to handle ban expires.

I cant seem to figure out what to bind to, I tried using:

Code:
BOT

bind bot <flags> <command> <proc>
proc-name <from-bot> <command> <text>

Description: triggered by a message coming from another bot in the botnet. The first word is the command and the rest becomes the text argument; flags are ignored.

Module: core


But the bot didnt return anything with this code:

Code:
bind bot - * randomprocname

proc randomprocname { from cmd text } {
  putlog "FROM: $from CMD: $cmd TEXT: $text"
}



Code:
[17:14] BotA: cancel ban *!*@exezic.users.quakenet.org on #dota.no


which I received on another bot in the botnet (BotB), which was running the script...

Any ideas?

Maybe it's something about the bind I'm missing, considering it's not stackable... Maybe it should be bound to something. But I'm not sure what the <command> is...



On a sidenote; I have access to compiling the bot myself. So if you could point out what I would need to do to make the bot detect whenever a ban expire, that would do aswell Smile


Ok, so I figured out it wasn't actually in src/mod/irc.mod/irc.c function. It was actually in src/mod/channels.mod/userchan.c

I also found my way to the code:

Code:
/* Check for expired timed-bans.
 */
static void check_expired_bans(void)
{
  maskrec *u, *u2;
  struct chanset_t *chan;
  masklist *b;

  for (u = global_bans; u; u = u2) {
    u2 = u->next;
    if (!(u->flags & MASKREC_PERM) && (now >= u->expire)) {
      putlog(LOG_MISC, "*", "%s %s (%s)", BANS_NOLONGER, u->mask, MISC_EXPIRED);
      for (chan = chanset; chan; chan = chan->next)
        for (b = chan->channel.ban; b->mask[0]; b = b->next)
          if (!rfc_casecmp(b->mask, u->mask) &&
              expired_mask(chan, b->who) && b->timer != now) {
            add_mode(chan, '-', 'b', u->mask);
            b->timer = now;
          }
      u_delban(NULL, u->mask, 1);
    }
  }
  /* Check for specific channel-domain bans expiring */
  for (chan = chanset; chan; chan = chan->next) {
    for (u = chan->bans; u; u = u2) {
      u2 = u->next;
      if (!(u->flags & MASKREC_PERM) && (now >= u->expire)) {
        putlog(LOG_MISC, "*", "%s %s %s %s (%s)", BANS_NOLONGER,
               u->mask, MISC_ONLOCALE, chan->dname, MISC_EXPIRED);
        for (b = chan->channel.ban; b->mask[0]; b = b->next)
          if (!rfc_casecmp(b->mask, u->mask) &&
              expired_mask(chan, b->who) && b->timer != now) {
            add_mode(chan, '-', 'b', u->mask);
            b->timer = now;
          }
        u_delban(chan, u->mask, 1);
      }
    }
  }
}


I hope someone here can speak in c Smile

Basically, I think I need some sort of bind which will react whenever a function is run. For instance, if I had put a function named event_expireban underneath

Code:
       putlog(LOG_MISC, "*", "%s %s %s %s (%s)", BANS_NOLONGER,
               u->mask, MISC_ONLOCALE, chan->dname, MISC_EXPIRED);


like so:

Code:

  /* Check for specific channel-domain bans expiring */
  for (chan = chanset; chan; chan = chan->next) {
    for (u = chan->bans; u; u = u2) {
      u2 = u->next;
      if (!(u->flags & MASKREC_PERM) && (now >= u->expire)) {
        putlog(LOG_MISC, "*", "%s %s %s %s (%s)", BANS_NOLONGER,
               u->mask, MISC_ONLOCALE, chan->dname, MISC_EXPIRED);
        -->event_expireban();<--
        for (b = chan->channel.ban; b->mask[0]; b = b->next)
          if (!rfc_casecmp(b->mask, u->mask) &&
              expired_mask(chan, b->who) && b->timer != now) {
            add_mode(chan, '-', 'b', u->mask);
            b->timer = now;
          }
        u_delban(chan, u->mask, 1);
      }
    }



and if the event_expireban() function would somehow be detected by

Code:
bind evnt - expireban procedurename


in the same way rehash is detected by

Code:
bind evnt - rehash procedurename


Then that would solve my problem, only problem is... I don't know how to do this :\

Any help will be greatly appreciated!
