Ah, the dangers of porting code from other bases :P

Nice catch Conner. Fixed.

As much as I appreciate that, I really must defer to Remcon on this one. I installed it as he wrote it, then when I ran into a similiar issue to the one Zeno found, I patched it with your solution of reverting the memory macros, but it still didn't fully solve the problem, so I asked Remcon to help me decipher the core file it had produced and he helped me figure out that this was the problem/solution and when we were done, he asked me to post it here for others too. So, while I love seeing my name in lights like everyone else, I'll pass the credit for this one on to Remcon because it's really where it is due. Besides, overall, this whole cleanup_memory addition is his baby, from cradle to grave. :)

lol thanks but i have to pass it on to samson, or who ever first came up with it :) I just tried to make it fit into stock smaugfuss the problem with some of it is that in stock smaugfuss it doesnt have data in everything and these problems arent noticed until one searched for each part and made sure its done right or there is a problem which makes someone check a part :) thanks for finding the issue and making it known to others :)

in comments.c
find
      /*

      strtime = ctime( ¤t_time );
      strtime[strlen( strtime ) - 1] = '\0';
      ch->pnote->date = STRALLOC( strtime );

replace that with this
      /*
       * act( AT_ACTION, "$n posts a note.", ch, NULL, NULL, TO_ROOM );
       */

      strtime = ctime( ¤t_time );
      strtime[strlen( strtime ) - 1] = '\0';
      STRFREE( ch->pnote->date );
      ch->pnote->date = STRALLOC( strtime );

Its not freeing the date and it appears it is already set elsewhere :)

It seems that item scraps aren't being cleaned up when the MUD is shutdown.

Total strings in hash 24: 1
Len:  28 Lnks:    1 Str: the remnants of A Cup
Total strings in hash 28: 1
Len:  46 Lnks:    1 Str: The remnants of A Cup are strewn about.
Total strings in hash 46: 1
Cleanup complete, exiting.


Any way to fix this? Codebase I'm using is FUSS 1.4.

Well the objects were cleaned up but apparently the hashed descriptions weren't. Can you post a copy of your make_scraps() function?

Well I'm at a loss. I don't see anything wrong with the function. Were there any specific steps you followed to make this happen?

Well not really, I was testing a few modifications I made to the fighting system and fought with a mob, which destroy my my item and I picked it up and shutdown the MUD. Then I saw the output, and the mods I did were changing the message displaying.

I was thinking it could have something to with clean_obj_queue() or extract_obj, but the item scraps are the only things that pop up.

Has anyone had problems with the global boards? Every time I shutdown it shows all gnotes in every board and that can become quite spamful. :(

Total strings in hash 0: 1
Len:   3 Lnks:    2 Str: All
Total strings in hash 3: 1
Len:   7 Lnks:    2 Str: Testing
Total strings in hash 7: 1
Len:  10 Lnks:    1 Str: Testing.
Total strings in hash 10: 1
Len:  24 Lnks:    1 Str: Sun Jul 30 20:44:17 2006
Total strings in hash 24: 1

Memory Cleanup Complete.


I tried to fix it, but I later found out I was approaching the problem the wrong way and got tired of trying. (I thought it was caused by players not reading new gnotes, but I was wrong.) So if any one has any suggestions or anything please let me know.

for the load_char_obj memory leak... characters aren't automatically added to the first_char last_char list on load... they are added once they get to CON_PRESS_ENTER i believe. :P search descriptors for d->character.

Thanks for the suggestion, but the problem has been fixed. I've been adding fixes to the MUD from the SMAUG fix list and the obj_queue fix solved the problem. :smile:

As for the global_board problem, it looks like it might have to be changed on how it loads up boards. :/

So, since this is related to this topic, instead of creating a new one, figured I'd add it here.
Alright, discovered this, as it started today, when an Imm rebooted MW after bombing an area. but MW never came back up, well, I set about finding out why, and low and behold....

Now, I've stayed pretty on top of this thread since I put this into the Obscurities code, watching for fixes and adding them. And for this to randomly start today, is mind boggling. If there's anything else you need, let me know, and I'll get it. If you want to treat me like I'm retarded, which I probably am, just spell out what you want me to do to get whatever information, and i'll ensure I follow directions. :tongue:
