Hi everyone,

I'm using the DW distribution lib with FluffOS 2.20-ds01, on linux, and was wondering if anyone else ran into a problem with mob spawn causing a seg fault, in pumpkin town (on squash street).

This is the trace I get

Object: /d/dist/pumpkin/squash/squash4, Program: /d/dist/pumpkin/inherit/cityroom.c
   in make_citymonster() at /d/dist/pumpkin/inherit/cityroom.c:61
arguments were (0)
Object: /d/dist/pumpkin/hospital, Program: /d/dist/pumpkin/hospital.c
   in ok_to_clone() at /d/dist/pumpkin/hospital.c:490
arguments were ()
Object: /secure/simul_efun, Program: /secure/simul_efun/modified_efuns.c
   in named_livings() at /secure/simul_efun/modified_efuns.c:232
arguments were ()
'     <fake>' in '/            <driver>' ('/   secure/simul_efun')

I checked the hospital.c files first (there's a couple of them), and I think the piece of code in question is trying to count the mobs in Ankh-Morpork, which isn't part of the distributed lib:

// This function returns 1 if its ok to clone some more npcs and
// false if not.
int ok_to_clone() {
  if(time() > last_check + 300) {
    last_check = time();
    am_npcs = sizeof( filter( named_livings(),
      (: environment( $1 ) && base_name( environment( $1
       ) )[0..4] == "/d/am" :) ) );
  }
  return ( am_npcs < MAX_AM_LIVING );
}
where "/d/am" doesn't exist, but MAX_AM_LIVING is defined in another file alright.  however, there are also 4 hospital files to do with pumpkin, one in /d/dist/pumpkin, and the others in /d/dist/pumpkin/pumpkin, /d/dist/pumpkin/inherit, and /d/dist/pumpkin/hospital.  pumpkin's path.h only points to the one in the base pumpkin folder, though (i also just found a typo where it was referring to hostpial.h, but i don't think that's the issue since each hospital.c has hospital.h included at the top)

i think there's also something wrong with named_livings(), but i have no idea what the trace is saying.  the e_fun code in the trace is simply:

/** @ignore yes */
object *named_livings() {
#if efun_defined(named_livings)
  return filter( efun::named_livings(), (: reference_allowed :) );
#else
  return filter( LIV->named_livings(), (: reference_allowed :) );
#endif
} /* named_livings() */
any input would be appreciated!

edit: this doesn't happen all the time, only if i leave the mud running a while (presumably when the number approaches/hits the max?)

heh, running a search on the two area names he mentioned, it looks like it's Merentha, or perhaps if Merentha distributes those areas with their code, a mud that uses the Merentha lib.

after browsing through the code, it looks like the discworld files for maps are still included in the lib... does anyone know how to use them with skylib, by chance?

Crat, you're not unaccommodating!  Don't be silly.

I think that I'm a fair newbie at LPC, so I appreciate the fact that you're watching out for us, making sure we don't do more damage than necessary.

And like you said in another post, I can always just use windows explorer to search through files, if I'm desperate

Hello everyone,

I just started looking at Skylib, and so far it looks awesome.  A big thanks to Cratylus for making the bundle that works on windows

I ran into a bit of a problem with the 'grep' command internal to the mud, and traced it back to an external_start efun.  The mud says:

/secure/cmds/creator/grep.c line 61: Undefined function external_start before ;

where line 61 is where grep.c uses external_start:

    if( nfiles || !search )
        fd = external_start( 6, arg, "read_call_back",
            "write_call_back", "close_call_back");
    else
        return notify_fail("Grep needs at least one file.\n");

    if( fd == -1 )
        return notify_fail("Grep failed for some reason.\n");

looking at the help file for external_start, it says the first parameter passed should be an int, for one of five external commands specified in the config file.  could the fact that it's a 6 be messing it up?

i'm running skylib right out of the bundle (with the included fluffos-2.9).

any advice would be greatly appreciated!

hmm, i put something similar to:

string longdesc = NewLong();

outside of the create function, and then did

SetLong(longdesc);

inside the create, and it's still resetting the desc every time i quit and re-log.

wow, this is exactly the same sorta thing that i was looking for sweet deal

ps, personally i'd want a "bursting koi".
