Infinite loop at startup

I don't know how it happened, or where it may have happened, I had the entire thing running earlier, and now that I've tried to get it public, I get this. Since I'm really rusty on the entire coding thing, and new to Cygwin, where do I start to look for this loop?

Nick Gammon Australia Forum Administrator Tue 15 Dec 2009 10:20 PM #1

Do you mean CPU usage goes up to 100%? How do you know it is in a loop?

Daraku Tue 15 Dec 2009 10:30 PM #2

You have a point, I suppose. Then my problem is a crash at login... I've been testing some, but again, not sure where to look or how. :/

Hanaisse Canada Tue 15 Dec 2009 10:37 PM #3

Could you be more specific about "tried to get it public" and what, if any, errors you are getting?

Does it crash? When does it crash? What is the last command before it crashes? Have you checked your logs for bug or error messages?

Daraku Tue 15 Dec 2009 10:54 PM #4

Well, I'm running a router, and through various posts and whatnot, I found I'd have to port forward through it to my PC. That didn't work, as no-one could connect, and as soon as I was kicked, I couldn't connect again. ./startup would do nothing, no output, MUD still down. I gave up, deleted the src, and went back and started once more, doing what I did before, and even doing what you suggested with the uncommenting of the logs, Hanaisse. Make displays no errors that I can see, and when I ./startup 6000, it doesn't display anything. When I connect, I get "Connecting...", then next line is "Disconnected" in my MUD client.

From my understanding, the MUD should be up, no? But when I go to connect:

Quote:

%%% Connecting to <localhost ip> on port 6000
%%% Connected to localhost on port 6000.
%%% Disconnected from server.

I've checked the logs, but there's nothing in them, just that the MUD started up as it was supposed to.

Nick Gammon Australia Forum Administrator Tue 15 Dec 2009 10:59 PM #5

Instead of startup, try running manually:


cd ../area
../src/dbsaga 6000

Then watch the messages fly by. If it doesn't immediately return to the command prompt with an error message, then try connecting and see what happens.

Daraku Tue 15 Dec 2009 11:20 PM #6

This is wierd. It started up fine again, housing errors aside, and when I went to log in, kicked to the prompt and disconnected me from the MUD client, no errors that I can see in Cygwin.

I don't see anything about me attempting to connect, nor do I see anything buggy when I try to connect. :/
This thing is a pain. I had it working earlier

Nick Gammon Australia Forum Administrator Tue 15 Dec 2009 11:41 PM #7

It looks to me like the bug re echo_to_room() is a fatal error, causing the server to exit, since that was the last thing you saw.

I would be a bit worried about the bugs like "BUG: Cannot load house file: Aburame" - sounds like some files aren't there.

Try and get rid of all those loading bug errors. If that doesn't help you may have to fire up gdb and work out exactly what is happening:

http://mushclient.com/gdb

Daraku Tue 15 Dec 2009 11:46 PM #8

All I can say is those bugs were already there when I had it running before. I'll clean them up, but I'm more focused on getting the MUD back up and running right now, so gdb it is.

Hanaisse Canada Tue 15 Dec 2009 11:52 PM #9

Was this an existing MUD you're restarting? A clean copy of DBSC doesn't contain houses. What I would do is go to the /houses folder and remove all the files, except for the required ones;

homeaccessories.dat
homebuy.dat
house.lst

Save the actual house files to another folder on your HD if you want to keep them. Then update house.lst so it looks like this;

It appears to me to be something wrong with the house files. Removing them from startup may allow you to at least connect to your mud and debug from there.

Daraku Wed 16 Dec 2009 12:22 AM #10

Removed the house files, still can't get passed the "disconnected" from MUD client upon connecting. I'm just going to take a break from this for now, I've been working on it all day.

Hanaisse Canada Wed 16 Dec 2009 12:32 AM #11

Did you make clean/make?
What errors do you see on startup now?

Daraku Wed 16 Dec 2009 11:26 AM #12

Alright, cleaned it up, did 'make' again. I'm seeing all the same things in startup as before, minus the house problems. And same as before, it seems to start, syslog shows it starting up, but the second I try to log into the game from my MUD client, I get the

Quote:

%%% Connecting to <localhost ip> on port 6000
%%% Connected to localhost on port 6000.
%%% Disconnected from server.

All I can say is, there's gotta be something wrong in one of the files associated with people logging in... I don't know... -.-

Hanaisse Canada Wed 16 Dec 2009 01:32 PM #13

Is there a reason you're using port 6000 instead of typical 4000? A quick google search brings up many pages that basically say..

Quote:
This is pretty much an obvious sign of a firewall or other security program getting in the way. You might have gotten a pop-up window warning that a program (either XWin.exe or ssh.exe) was trying to make or accept a connection on port 6000. If you told the firewall to block it, that's the problem.
If your firewall or security program is set to block unexpected connections without even asking you, that could be the problem.
The easiest way to check this would be to teporarily turn off your firewall and security software, then try launching an X client again.

Change to port 4000 in your startup file and try again.

If that doesn't work, gdb it is then.
Instead of going into your src directory and using the startup go to your area directory and type;

gdb ../src/DBSaga

and then;

run 6000

Post the results.

Nick Gammon Australia Forum Administrator Wed 16 Dec 2009 07:24 PM #14

I added a bit to my gdb posting, on this page:

http://www.mushclient.com/gdb

It mentions you can put a breakpoint on "exit" in case the MUD is choosing to exit. Then you can see why.

Daraku Thu 17 Dec 2009 01:11 PM #15

Everything looks fine, until I try to log in. Here is what it looks like at this moment, I haven't logged in through a client yet:

I guess I didn't see it. I saw a reference to it, but it wasn't actually the problem. Here's the code, I can't see what is wrong with it, and I showed it to a friend who dabbles in code, but he's almost as rusty as I am, and he said the same, that it should be working.


{
	BAN_DATA *pban;
	char new_host[MAX_STRING_LENGTH];
	int i;

	for ( i = 0; i < (int) strlen( d->host ) ; i++ )
		new_host[i] = LOWER( d->host[i] );
	new_host[i] = '\0';

	for ( pban = first_ban; pban; pban = pban->next )
	{
		if ( pban->level != LEVEL_SUPREME )
			continue;
		if ( pban->user && str_cmp( d->user, pban->user ) )
			continue;
		if ( pban->prefix && pban->suffix &&
		     strstr( pban->name, new_host ) )
		{
			if ( check_expire( pban ) )
			{
				dispose_ban( pban, BAN_SITE );
				save_banlist( );
				return FALSE;
			}
			else
				return TRUE;
		}
		/*
		 *   Bug of switched checks noticed by Cronel
		 */
		if ( pban->suffix && !str_prefix( pban->name, new_host ) )
		{
			if ( check_expire( pban ) )
			{
				dispose_ban( pban, BAN_SITE );
				save_banlist( );
				return FALSE;
			}
			else
				return TRUE;
		}
		if ( pban->prefix && !str_suffix( pban->name, new_host ) )
		{
			if ( check_expire( pban ) )
			{
				dispose_ban( pban, BAN_SITE );
				save_banlist( );
				return FALSE;
			}
			else
				return TRUE;
		}
		if ( !str_cmp( pban->name, new_host ) )
		{
			if ( check_expire( pban ) )
			{
				dispose_ban( pban, BAN_SITE );
				save_banlist( );
				return FALSE;
			}
			else
				return TRUE;
		}
	}
	return FALSE;
}

I'm not so sure that line is the actual problem, as it's the same code across all the Smaug codebases. That is where the Seg Fault occurs, but it is not telling us why.

Did the seg fault dump any core files? Check in your main DBSaga dir. If so, try this;

gdb DBsaga core.11231

(change the core file # to whatever you have)

Did that seg fault occur when you tried to connect?

Since it is failing here:


1116 for ( i = 0; i < (int) strlen( d->host ) ; i++ )

... you need to reproduce the crash in gdb, and then get some debugging information out. My page about gdb should help.

For one thing, find out about the variables that have caused the crash, almost certainly d and d->host.

First thing to do is type:

bt

That shows a backtrace, which shows where this code was called from. Then look at the variables:


p d
p d->host

Wierd. I have a "stackdump" file in my areas folder, now. :/ Is this what I am supposed to be looking for? Heh.

You can reproduce it every time, right? So don't muck around with old core files, just run the MUD under gdb the way I described earlier.
