Conflict with gamemode/other plugins

[AndreT]

Hi.

Thanks for your creation. However I'm having trouble getting the profiler to work for my gamemode, which is quite extensive when it comes to plugin usage and functionality. Then again, I'm sure I'm not the only one with such gamemode who has tried to use profiler plugin. (I am running it locally on Windows)

The plugins that I use are:

• Streamer plugin 2.6 (doesn't use gdk for callback hooks)
• MySQL plugin by BlueG R6-2
• sscanf (not update 2.5, the one before, no gdk dependency?)
• GVars 1.3
• CTime library
• CSTL

Here's what my server.cfg looks like:
echo Executing Server Config... lanmode 0 port 7777 hostname SFSE announce 1 query 1 weburl www.SF-SE.net maxnpc 10 onfoot_rate 40 incar_rate 40 weapon_rate 40 stream_distance 300.0 stream_rate 1000 maxplayers 24 rcon_password whatthefuckisthisshit gamemode0 SFSE plugins profiler streamer mysql sscanf gvar CTime cstl password testsvr profile_gamemode 1 profile_format html call_graph 1

There are 2 lines in the log associated to the profiler:
`[20:04:32] [profiler] Loaded debug info from 'gamemodes\SFSE.amx'
[20:04:32] [profiler] Attached profiler to 'gamemodes\SFSE.amx'``

It crashes instantly after:
[20:04:32] Number of vehicle models: 113

And here is what crashinfo tells me:

From what I see in the crash log it is not related to profiler at all - the server crashed inside format(), perhaps due to wrong format specifier. Try running crashdetect to be sure.

[AndreT]

Thanks for the feedback, I ran it with crashdetect enabled.

[debug] Backtrace (most recent call first): [debug] #0 native format() from samp-server.exe [debug] #1 Debug(DEBUG_TYPE=3, fstring[]=@0x00028618 "OnHousesLoad(%d, %d, %d)") at SFSE_functions.pwn:3346 [debug] #2 public OnHousesLoad(query_ex[]=@0x00000003 "", index=165400, extraid=619200, connectionHandle=619204) at SFSE_houses.pwn:79

This is the result of Y_Less' combination of yours and his format code using #emit. Nothing there has changed, and using the code without the profiler plugin works perfectly.

But I could get some cool information by disabling my custom debug function.

[Zeex]

Does this function crash in empty script? Or is it specific to OnHousesLoad? What happens when you comment it out?

[AndreT]

I have edited the bare gamemode a little to replicate the crash. Here it is: http://pastebin.com/ML88WzB6

It happens when a string parameter is passed to the Debug function! I hope you can work out the problem :)

[Zeex]

Change

        #emit LOAD.I
        #emit PUSH.pri
        arg_end -= BYTES_PER_CELL;
        #emit LOAD.S.pri      arg_end

to

        #emit LREF.S.pri arg_end
        #emit PUSH.pri
        arg_end -= BYTES_PER_CELL;

in the do-while loop.

[AndreT]

Thank you, this made it work perfectly! If you have the time, could you explain the difference to me a little. And does this mean that anyone using Y_Less' code would need to change that?

Also, another small question: Since my server crashes when being gmx-ed on linux (CentOS distro), I saw this in my error log:

    [12:00:44] [debug] Run time error 4: "Array index out of bounds"
    [12:00:44] [debug]   Accessing element at negative index -1
    [12:00:44] [debug] Backtrace (most recent call first):
    [12:00:44] [debug] #0  public Streamer_OnPlayerDisconnect(playerid=4, reason=1) at SFSE.pwn:822
    [12:00:44] [debug] #1  native CallLocalFunction() from samp-server.exe
    [12:00:44] [debug] #2  public Streamer_OnPlayerDisconnect(playerid=4, reason=1) at SFSE.pwn:822

I had a look around in Streamer_OnPlayerDisconnect and a few other sections, but cannot find anything related. Should I contact the plugin author about the issue or is there something simpler on my hands?
