sometime I need to check and see what all the temps etc can modify just to see if there is a good reason not to stop them at the max needed for the highest lol

lol that would probably be a good idea



although right now I'm trying to implement some housing code and I need a bit of help


this is the housing snippet off of mudbytes I found a link to in a forum on here

which would be here:
http://www.mudbytes.net/index.php?a=files&s=viewfile&fid=2399


I've gotten quite a few of the errors and warnings gone, but one is stumping me

this is the line the error is complaining about

			for ( mreset = addloc->area->first_reset; mreset; mreset = mreset_next )
			{

				mreset_next = mreset->next;

				if ( is_room_reset( mreset, addloc, addloc->area ) )
					delete_reset( addloc->area, mreset );

			}

here is the whole thing

bool remove_house( CHAR_DATA *ch)
{
   HOME_DATA *homedata = NULL;	
   ROOM_INDEX_DATA *location, *addloc = NULL;
   OBJ_INDEX_DATA *key = NULL;
   OBJ_DATA *obj = NULL;
   CHAR_DATA *mob, *mob_next = NULL;
   EXIT_DATA *pexit = NULL;
   char filename[256];
   sh_int i = 0;
   RESET_DATA *mreset, *mreset_next = NULL;

	for (homedata=first_home; homedata; homedata=homedata->next)
	{
		if (!str_cmp( homedata->name, ch->name))
			break;
	}

	if (!homedata)
		return FALSE;	

	if ((location = get_room_index(homedata->vnum[0])) == NULL)
		return FALSE;

	while ( (obj = location->first_content) != NULL)
		extract_obj(obj);

	for ( mob = location->first_person; mob; mob = mob_next)
	{
		mob_next = mob->next;

		if ( IS_NPC(mob))
			extract_char( mob, TRUE);

	}

	sprintf( filename, "%s%s", HOUSE_DIR, capitalize( homedata->name ) );

	remove( filename );

	STRFREE(homedata->name);

	if (homedata->vnum[1] > 0)
	{

		for ( i=1; i < MAX_HOUSE_ROOMS; i++)
		{
			if (homedata->vnum[i] <= 0)
				continue;

			if((addloc = get_room_index(homedata->vnum[i])) == NULL)
			{
				homedata->vnum[i] = 0;
				continue;
			}

			for ( pexit = addloc->first_exit; pexit; pexit = pexit->next )
			{
				if (pexit->rexit)
					extract_exit(pexit->to_room, pexit->rexit);
				
			}

			for ( mreset = addloc->area->first_reset; mreset; mreset = mreset_next )
			{

				mreset_next = mreset->next;

				if ( is_room_reset( mreset, addloc, addloc->area ) )
					delete_reset( addloc->area, mreset );

			}

			
			homedata->vnum[i] = 0;

			delete_room(addloc);

this is the error it is giving me and I'm kind of at a loss on how to fix it

house.c:1664: error: âAREA_DATAâ has no member named âfirst_resetâ

also

	for (i=0; i < MAX_HOUSE_ROOMS; i++)
	{
		if (homedata->vnum[i] > 0 
			&& (location = get_room_index(homedata->vnum[i])) != NULL)
		{
			obj = location->last_content;
			j=supermob->level;
			supermob->level=MAX_LEVEL;

			if (obj)
				fwrite_obj(supermob, obj, fpout, 0, OS_CARRY );
			supermob->level=j;
		}
	}

my mud doesn't have levels so I would appreciate any ideas on how to fix this as well.

			for ( mreset = addloc->area->first_reset; mreset; mreset = mreset_next )
			{

				mreset_next = mreset->next;

				if ( is_room_reset( mreset, addloc, addloc->area ) )
					delete_reset( addloc->area, mreset );

			}

resets are room based and the delete_room will take care of the resets so you dont need that part

change

	for (i=0; i < MAX_HOUSE_ROOMS; i++)
	{
		if (homedata->vnum[i] > 0 
			&& (location = get_room_index(homedata->vnum[i])) != NULL)
		{
			obj = location->last_content;
			j=supermob->level;
			supermob->level=MAX_LEVEL;

			if (obj)
				fwrite_obj(supermob, obj, fpout, 0, OS_CARRY );
			supermob->level=j;
		}
	}

to

	for (i=0; i < MAX_HOUSE_ROOMS; i++)
	{
		if (homedata->vnum[i] > 0 
			&& (location = get_room_index(homedata->vnum[i])) != NULL)
		{
			obj = location->last_content;

			if (obj)
				fwrite_obj(supermob, obj, fpout, 0, OS_CARRY );
		}
	}

So I understand you just deleted the whole reference to supermob


what did the supermob do?


and I can't believe I didn't think of just removing it. lol

not the whole reference just the changing its level. In smaug you have to give it max level to make sure it saves all objects since it wouldn't save any object that was over the supermobs level.

So now I seem to have a problem with copyover


In another thread Zeno said this:

As for load_char_obj, hotboot was put in, so you'll need to fix those to work with hotboot. (It requires adding one more bool)

But honestly I have no idea how to go about doing this .... I know that makes me sound like a retard lol

There is only one instance of load_char_obj in house.c

CHAR_DATA *load_player( char *name )
{
   CHAR_DATA *onlinechar = NULL;
   DESCRIPTOR_DATA *d = NULL;
   struct stat fst;
   char buf[MAX_STRING_LENGTH];
   int oldvnum = 0;
   
    sprintf( buf, "%s%c/%s", PLAYER_DIR, LOWER(name[0]),
		capitalize(name) );

	for ( onlinechar = first_char; onlinechar; onlinechar = onlinechar->next )
	{

		if ( IS_NPC(onlinechar) ) 
			continue;

		if ( !str_cmp( onlinechar->name, name ) )
			return onlinechar;

	}

	if ( !check_parse_name( name, FALSE) )
		return NULL;

	if ( stat( buf, &fst ) == -1 )
		return NULL;

	CREATE( d, DESCRIPTOR_DATA, 1 );
	d->next = NULL;
	d->prev = NULL;
	d->connected = CON_GET_NAME;
	d->outsize = 2000;
	CREATE( d->outbuf, char, d->outsize );
	load_char_obj( d, name, FALSE );
	add_char( d->character );


	oldvnum = ((get_room_index(d->character->in_room->vnum)) != NULL) ? d->character->in_room->vnum
		: ROOM_VNUM_LIMBO;

	
	char_to_room( d->character, get_room_index(oldvnum));

	d->character->retran = oldvnum;

	d->character->desc	= NULL;

	d->character		= NULL;	
	DISPOSE( d->outbuf );
	DISPOSE( d );

	for ( onlinechar = first_char; onlinechar; onlinechar = onlinechar->next )
	{

		if ( IS_NPC(onlinechar) ) 
			continue;

		if ( !str_cmp( onlinechar->name, name ) )
			return onlinechar;

	}

	return NULL;
}

it isn't really needed to do that. if no problems just continue on. It is only really used to keep from showing you the last site you were connected from, at least in LoP lol

Hmm I'm thinking I did something else wrong


because I can't savearea, can't copyover, hmm

I guess I must have really borked something up lol

trying to decipher the core dump right now thought I'd post it up here so other people could look at it as well and possibly help me decipher

ah so its crashing on closing the fpreserve.

It had been awhile, but thought id check into it just to make sure. You don't need to have the fpreserve anymore anyways lol. And since I don't see it in the cm3 that means its already removed from the codebase so just remove the opening and closing of the fpreserve in the stuff you added.

If you don't mind me asking (because honestly I'm trying to understand gdb and how to read it) would you mind explaining to me how you came to understand that

I mean I see #4 5 and 6, and I mean of course I figured that it had something to do with do_save, but I figured that because when I tried to savearea it crashed


I'm really not trying to be a bother I just want to understand everything, and maybe one day I won't have to ask for so much help

Well 0, 1, 2, 3, 4 all seem to be after the actuall issue so 5 was a great spot to look at, 4 is good to see that the part in 5 is calling fclose though.

#5  0x000000000049b34d in fold_area (tarea=0x15b7250,
    filename=0x7fff83384bb0 "../building/Aasterinian.are", install=0 '\000') at build.c:7366

7364       sprintf( buf, "%s.bak", filename );
7365       rename( filename, buf );
7366       fclose( fpReserve );
7367       if( ( fpout = fopen( filename, "w" ) ) == NULL )
7368       {
7369          bug( "fold_area: fopen", 0 );
7370          perror( filename );

Now 5 shows that it is calling fclose on fpReserve which hasn't been used in quite some time and through experience I've seen it crash muds back when it was used lol. People do enjoy doing up and list as well as info locals etc... i normally just use frame <#> and then maybe a list to see what is around the issue and then I use print just to see what data it has there. for example i would have done

frame 5
list
print fpReserve
print *fpReserve

at the very least

Hah I wasn't sure what I was doing, but I took a chance lol and removed all references to fpreserve and it let me save and do a copyover



Reading over your post while I was working I will definitely try and remember to do the prints


so basically looking at the gdb you could tell that the first few we're after the crash, which I guess I can see

so you just basically (through experience) saw that #4 and 5 was a good place to start

and then of course once you do list you can see where it all takes place


and then once again through experience you know that fpreserve hasn't been used in forever so that really tipped your hat off to whats wrong

nice

Yep no worries you will learn lots as you go

I feel I'm actually learning pretty quickly

I added and changed a lot of that snippet from what I've learned without having to ask for help

so I'm a bit happy about that

you should be just takes lots of time lol

and sometime while I was at work my mud crashed

and when I go to load it back up segmentation fault
