Error with Atcommand Events diff

[sizenine]

I'm getting this error:

npc.c:784: undefined reference to `aMallocA'

from applying this diff by ToastOfDoom.. can anyone help me solve this?

http://www.eathena.w...howtopic=272578

Here is part of the src that shows line 784 in npc.c:

+int do_atcmd_event (struct map_session_data* sd, const char* command, const char* message, const char* eventname)
+{
+ struct event_data* ev = (struct event_data*)strdb_get(ev_db, eventname);
+ struct npc_data *nd;
+ struct script_state *st;
+ int i = 0, j = 0, k = 0;
+ char *temp;
+ temp = (char*)aMallocA(strlen(message) + 1);

+
+ nullpo_ret(sd);
+
+ if( ev == NULL || (nd = ev->nd) == NULL )
+ {
+ ShowError("npc_event: event not found [%s]n", eventname);
+ return 0;

replace aMallocA with aMalloc

Thanks that seems to have worked but now I found a possible glitch...

I've written somewhat of a small script to add a requirement for Emperium when using the command @guild:

- script atcmd_sample_inject -1,{

OnInit:
bindatcmd("guild", "atcmd_sample_inject::OnAtCmd");
end;



OnAtCmd:
if (.@atcmd_command$ == "$guild") { end; }
if(countitem(714) < 1) 
{
dispbottom "You need the necessary item to create a Guild.";
}
else
{
useatcmd "@guild " + .@atcmd_parameters$[0];
}
end;

}

After implementing that script, the @guild command works fine with the item requirement. However, when I try to use #guild <charname> <guildname>, the map server will receive a crash signal. Is there something wrong with my script? Or is this a flaw in the diff?

Probably has something to do with attached player when checking and "useatcmd"-ing, probably null reference in useatcmd. Put some console debug writers in that function and see what you get.

My guess is that it doesn't check whether <charname> is actually a character.

Sorry I'm not too familiar with console debug writers".. but I've tried it on actual existing char names and it still crashes the server.

[Derceto]

I mean, find the function "useatcmd" and fill it with ShowInfo() watches to see what happens when it crashes

[sizenine]

so i just stick a bunch of "ShowInfo()" between the code lines?

BUILDIN_FUNC(useatcmd)
{
TBL_PC dummy_sd;
ShowInfo();
TBL_PC* sd;
ShowInfo();
int fd;
ShowInfo();
const char* cmd;
ShowInfo();
cmd = script_getstr(st,2);

if (st->rid) {
ShowInfo();
sd = script_rid2sd(st);
ShowInfo();
fd = sd->fd;
ShowInfo();
} else { //Use a dummy character.
ShowInfo();
sd = &dummy_sd;
fd = 0;
ShowInfo();
memset(&dummy_sd, 0, sizeof(TBL_PC));
ShowInfo();
if (st->oid)
{
ShowInfo();
struct block_list* bl = map_id2bl(st->oid);
ShowInfo();
memcpy(&dummy_sd.bl, bl, sizeof(struct block_list));
ShowInfo();
if (bl->type == BL_NPC)
ShowInfo();
safestrncpy(dummy_sd.status.name, ((TBL_NPC*)bl)->name, NAME_LENGTH);
ShowInfo();
}
ShowInfo();
}

// compatibility with previous implementation (deprecated!)
if(cmd[0] != atcommand_symbol)
{
ShowInfo();
cmd += strlen(sd->status.name);
ShowInfo();
while(*cmd != atcommand_symbol && *cmd != 0)
ShowInfo();
cmd++;
}
ShowInfo();
is_atcommand(fd, sd, cmd, 2);
ShowInfo();
return 0;
}

lol... like that? i dont know what im doing obviously.

[Derceto]

showinfo() is an extension (remake) of printf().

syntax: showinfo(formatString, ...)

Normally you would write

ShowInfo("useatcmd: somevariable = %d n", somevariable);

for integers. For floating point you use "%f" instead of "%d", for strings "%s".

But if you're asking it this far, I suppose you won't know what to do after that anyway. Wait for someone less lazy than me come by.

oh i see.. i know what printf() is but yeah i probably wouldn't know what the values mean and how to fix it even if i printed out the results..

Hello.. I didn't want to open another thread because, my concern is also about the atcommand events mod.

I get this error when I try to use #command.

What I added is just this line

  	 if( .@atcmd_command$ == "#testshop")
  	 { end; }

Here's what's written on npc.c line 782

nullpo_ret(sd);

npc.c

int do_atcmd_event (struct map_session_data* sd, const char* command, const char* message, const char* eventname)
{
struct event_data* ev = (struct event_data*)strdb_get(ev_db, eventname);
struct npc_data *nd;
struct script_state *st;
int i = 0, j = 0, k = 0;
char *temp;
temp = (char*)aMalloc(strlen(message) + 1);

nullpo_ret(sd);

if( ev == NULL || (nd = ev->nd) == NULL )
{
	ShowError("npc_event: event not found [%s]\n", eventname);
	return 0;
}

Quite hard to understand the issues here, not so familiar with Toasty diff to get an idea.

Anyway gdb would help on the matter, you may have some info here :

http://rathena.org/wiki/GDB

Or all you guys need to do is :

gdb -ex run map-server_sql

Than also run the 2 other part :

./login-server_sql

./char-server_sql

With this will have a better view of what may wrong when crashing. (use "bt full" when this append to have a more consistent report)
