[Plugin] CrashDetect

Crash example

Suppose we run the following game mode:

#include <a_samp>

main() {
    function1();
}

function1() {
    function2();
}

function2() {
    new buf[10];
    fread(File:123, buf);
}

By default when it comes to function2, your server will exit immediately and if you're running Windows it will dump some unreadable stuff to crashinfo.txt.

But with crashdetect, you see the following in your server log:

[05:26:38] [debug] Server crashed while executing crash.amx
[05:26:38] [debug] Backtrace (most recent call first):
[05:26:38] [debug] #0  native fread () from samp-server.exe
[05:26:38] [debug] #1  00000090 in ?? () from crash.amx
[05:26:38] [debug] #2  00000038 in ?? () from crash.amx
[05:26:38] [debug] #3  0000001c in main () from crash.amx

which is more informative. You can also get more information like line numbers, function names, parameter values, etc if compile that script in debug mode to make compiler put extra information about all that stuff into the output .amx (see here for how):

[05:27:11] [debug] Server crashed while executing crash.amx
[05:27:11] [debug] Backtrace (most recent call first):
[05:27:11] [debug] #0  native fread () from samp-server.exe
[05:27:11] [debug] #1  000000b8 in function2 () at crash.pwn:13
[05:27:11] [debug] #2  00000048 in function1 () at crash.pwn:8
[05:27:11] [debug] #3  00000024 in main () at crash.pwn:4

Runtime error

Run time errors are usually reported via the "Run time error <error_code>: "Error details here"" message. Unfortunately this message is rarely shown because the server doesn't always check for them.

Some example code by JernejL:

public OnGameModeInit() {
    new bla[5];

    new fffuuuu = 0;

    fffuuuu = 100;
    bla[fffuuuu] = 100;

    return bla[fffuuuu];
}

If you compile this code in debug mode mode and run it:

[05:32:16] [debug] Run time error 4: "Array index out of bounds"
[05:32:16] [debug]   Accessing element at index 100 past array upper bound 4
[05:32:16] [debug] Backtrace (most recent call first):
[05:32:16] [debug] #0  00000084 in public OnGameModeInit () at bounds.pwn:11

New server.cfg option

If you wanna make your server quit on first runtime error set the "die_on_error" var in server.cfg to 1.

Wow, this is just what I need! Good work

What.... This is not for PAWNO. It's for the samp-server.exe

This is amazing, and will help MANY people.

pass -d3 to compiler, this if for pawno

Setting compiler options via pawno\settings.ini doesn't work for some reason, but you can create a file "pawn.cfg" in pawno directory and specify compiler options there, i.e like in this topic:

http://forum.sa-mp.com/showthread.php?t=249897

Note that you need -d3 as I mentioned in the first post (maybe -d2 will work too - I didn't check)
