Duplicate CallBack call - RhaegarX - 2021-03-19

In my gamemode I use mysql as a data saving system. Most of the player data I will save the moment it is changed to avoid problems in case of server crash or crash, and I also save the player data when restarting the server (/ gmx).

PHP Code:
public OnPlayerDisconnect()
{
Player_DestroyAllVehicles(playerid);
Player_SaveRanking(playerid);
Player_SaveConfig(playerid);
Player_SaveMoney(playerid);
? ? Player_SaveData(playerid);
? ? Player_ClearVars(playerid);
Player_ClearAcessories(playerid);
Player_ClearInfo(playerid);
Inventory_Reset(playerid);
} 

PHP Code:
public OnGameModeExit()
{
    foreach(new i : Player)
    {
        Player_DestroyAllVehicles(i);
        Player_SaveRanking(i);
        Player_SaveConfig(i);
        Player_SaveMoney(i);
        Player_SaveData(i);
        Player_ClearVars(i);
        Player_ClearAcessories(i);
        Player_ClearInfo(i);
        Inventory_Reset(i);
    }
    DestroyAllDynamicMapIcons();
    DestroyAllDynamic3DTextLabels();
    DestroyAllDynamicPickups();
    mysql_close(ConexaoSQL);
    return 1;
} 

What I noticed is that when I restart the server, OnGameModeExit is saved and OnPlayerDisconnect is saved, doubling each player's save. For example: when I restart the server (/ gmx) the player's money is saved in OnGameModeExit and OnPlayerDisconnect, being saved 2 times without need.
How do I avoid this duplication of calls? Do I need to save player data on OnGameModeExit or just OnPlayerDisconnect?
Is OnPlayerDisconnect called by default by OnGameModeExit?

Code:
public OnGameModeExit() {

    ON_GAMEMODE_EXIT_SAVE = true;

    // ..SAVE

    return true

}

public OnPlayerDisconnect(playerid, reason) {

    if(ON_GAMEMODE_EXIT_SAVE == true)

        return false;

    // ..SAVE

    return true;

}

I don't know if the values of the variables are kept after gmx, I never used that
If they are, you will have to modify the variable in OnGamemodeInit setting as 'false'.

When the player disconnects I save the data and reset the variables.

For starters, dont use /gmx as it's unstable af

Use /rcon exit than start the server again.

Also, try on blank gm if the OPDC is called when you do /rcon gmx or /rcon exit, ion remember

Yes. I tested it on an empty gamemode and OnPlayerDisconnect is also being called when OnGameModeExit and / rcon gmx is called

Would that make saving on OnGameModeExit useless?

Yes, don't save anything player-related OnGameModeExit then.

Yes. I removed the save made on OnGameModeExit and everything works perfectly, OPDC is called when restarting the server and without duplicating the save

Still, I don't recommend usage of /rcon gmx, fresh start is always my go-to

There's nothing wrong with gmx. Someone was claiming that on discord the other day as well with no proof or explanation. I don't know where these rumors come from, nor why people are so quick to believe them. If you think you've found a bug, document it reproducibly, otherwise stop spreading misinformation.

Oh, sorry, someone very "knowledgeable" told me that actually so that's why I believed, like Illidan or someone like that idk
