I honestly do not know what to tell you..

I downloaded the same file I linked you to... I typed make in the src directory,

I cannot recreate what is happening on your end... so I am at a loss on what to tell you. I literally just did this with the same files...

No, I'll save you a step.

I cd ../area and then ../src/smaug while thinking to myself, "wtf, this is a really bad way to invoke a program."

And then it starts up, with

not very strong. each of them are easily resolvable and do not prevent the game from functioning. They aren't the problem

I believe it, because your version of GCC is about 70 years old. 4.4.0? I have 7.3.1. Anyway, I have it running.

Have you compiled it with debug flags enabled and attached a debugger to it?

no, honestly I have googled, read here about gdb debugging, I have exhausted the internet ... and for WHATEVER reason, I NEVER get the output the tutorials claim I should get. So gdb has been lost to me and I am stuck trying to rely on reasonable guesses and trial and error.

edit: I am starting to think that Smaug is haunted.

and again, thanks for helping with this. I saw on the MUD discord channel people talking about this snippet today, so others may run into this issue soon. If a solution is found it could save a lot of future headaches.

There was a bug in MUSHclient a while back where, under some circumstances, no data would be sent to the server. If you advise which version of MUSHclient you are using that would help.

Also, does my gdb tutorial not work? In what way?

So I run gdb ../src/smaug
then I tell it to run. then it runs.
then I hit ctrl-c and type bt and it shows me


#0  0x00007ffff6e0aad7 in select () from /lib64/libc.so.6
#1  0x00000000004d89b9 in game_loop () at comm.c:970
#2  0x00000000004d7851 in main (argc=1, argv=0x7fffffffdf88) at comm.c:551


Oh look. game_loop in comm.c.

So I open comm.c.

blah blah. game_loop. blah blah.

calls accept_new. what does that do?

blah blah.

calls new_descriptor. what does that do?

blah blah blah. lol bans. blah blah.

oh look, here it sends the greeting.

blah blah...and nothing else...

go back to game_loop ...

not idling out
...
not getting disconnected
...
not dns

...blah blah...

calls read_from_buffer. What does that do?

Gosh. The first thing it does is set read_buf[0] = '\0';

What an odd thing to do. I wonder what the effect of that is?

oh look. for i = 0 blah blah if( read_buf[i] == '\0') return;

So read_from_buffer does absolutely nothing. okaaayy.

blah blah...hm.. end of that loop.

update_handler?

blah blah blah nope.

Output sounds reasonable.

blah blah blah

ugh

blah blah

write_to_descriptor. finally. What does it do?

not much...

ugh. this is dumb. where does the password get set?

search for "password"

Oh look. nanny. Deal with sockets that haven't logged in yet.

So I need to make it to nanny. It's just after read_from_buffer.

Except the code will never get to nanny, because read_from_buffer does nothing.



This is just a wild guess, but did you edit this code, specifically read_from_buffer in comm.c, to make it do less than it used to?

the only thing I did to that was per instruction. 2 lines were added


In game_loop():

    read_from_buffer( d );
    if ( d->incomm[0] != '\0' )
    {
        d->fcommand     = TRUE;

        if ( d->pProtocol != NULL )      /* <--- Add this line */
            d->pProtocol->WriteOOB = 0;  /* <--- Add this line */

If d->fcommand is set to TRUE anywhere else, do the same there.

OK, this is my third attempt to get from you what version of MUSHclient you are using (if you are using it at all)?

but….. I can’t send any commands… my name, password… nothing lol

gdb is useful in two main situations:

  • The server crashes and you want to know why (this doesn’t seem to apply to you)

  • The code is doing something you don’t expect (this seems more to be your case)

In the first case, typing “bt” (backtrace) basically tells you where the code was when it crashed.

In the second case it is more useful to put a breakpoint in a function where you are expecting to be (eventually) and then see why branch X is taken when you expected branch Y.

So when you say you can’t send any commands, perhaps put a breakpoint in “nanny” and see if, when you send your name, nanny is even called.

You could also turn on packet debugging in MUSHclient - perhaps what is happening is that data is arriving, but being discarded for some reason.

sorry nick, i didn't see that message. I am trying this on Zmud (newest version trial), Gmud, Mudlet 3.9, and beipMU 3.0

all yielding no results.

edit: and fiendish, I checked my read_from_buffer function against stock, and nothing inside the function itself was changed.
