C++ a kopie pointeru...

ariczek · November 21, 2011

Nějak jsme teď na hulákadle nakousli problém s ukazatelema, delete a check na NULL...

například:

#include <iostream>
using namespace std;

int main(int argc, char* argv[]) {
 int * a = new int;
 *a = 8;
 cout << a << " " << *a << endl;
 delete a;
 if (a) {
   cout << a << " " << *a << endl; }
 return 0;
}

se provede i ten spodni cout

vystup:

0x8792008 8
0x8792008 0

dalo by se to trochu vyřešit přidáním úrovně ukazatelů...

#include <iostream>
using namespace std;

int main(int argc, char* argv[]) {
 int ** a = new int*;
 *a = new int;
 **a = 8;
 cout << *a << " " << **a << endl;
 //co kdyz nekde dame b, kopii... a o pul hodiny pozdejc to deletnem v a, ale b uz nemame pod kontrolou ? 
 int ** b = a;
 delete *a;
 *a = NULL;
 if (*a) {
   cout << *a << " a " << **a << endl;
 }
 if ( *  {
   cout << *b << " b " << **b << endl;
 }
 delete a;
 a = NULL;
 //delete b - tady by to crashlo  double delete 
 b = NULL; 
 return 0;
}

takhle nejako

vystup:

0x8c4c018 8

nenapada nekoho jeste lepsi reseni ?

EDIT: hlavně mi tam jde o to řešení u b v druhém příkladu když nemůžu ručně změnit ukazatel na NULL, protože ho neznám.

int ** b = &a;

ariczek · November 21, 2011

int ** b = &a;

to je v podstatě jinak zapsané řešení s přidáním úrovně ukazatele

#include <iostream>
using namespace std;

int main(int argc, char* argv[]) {
 int * a = new int;
 *a = 8;
 cout << a << " " << *a << endl;
 int ** b = &a;                                                                                              
 delete a;
 a = NULL;
 if (a) { 
   cout << a << " a " << *a << endl;
 }
 if (*b ) {
   cout << *b << " b " << **b << endl;
 }  
 b = NULL;
 return 0;
}

Abych uvedl, co jsem neuvedl - na hulákadle jsme řešili že core spadne v handleru std::set (tam chyba nebude) i když Player* neni NULL, protože je to pravděpodobně kopie, která se smazala z jiného ukazatele... (jiny thread ?)

Takže tohle řešení by v daných místech vyžadovalo přidání hvězdiček navíc... to mi pořád přijde ujeté, není ještě jiná možnost ?

To, že první příklad vyřešíš takto ti je jasný?

#include <iostream>

using namespace std;

int main(int argc, char* argv[]) {
 int* a = new int;
 *a = 8;
 cout << a << " " << *a << endl;
 delete a, a = NULL;
 if (a) {
   cout << a << " " << *a << endl;
 }
 return 0;
}

Tady máš řešení toho tvého druhého problému. Přes reference.

#include <iostream>

using namespace std;

int main(int argc, char* argv[]) {
 int* a = new int;
 int*& b = a;
 *a = 8;
 cout << a << " a: " << *a << endl;
 cout << a << " b: " << *b << endl;
 delete a, a = NULL;
 if (a) {
   cout << a << " a: " << *a << endl;
 }
 if (b ) {
   cout << b << " b: " << *b << endl;
 }
 return 0;
}

ariczek · November 22, 2011

jasny, to prvni byla jen ukazka, ze samotnej delete nestaci, jeste je potreba nastavit ukazatel na NULL. V podstate jen ilustrovalo kdyz to smazes, ale neprepises ukazatel, co se stane.

to druhy je moc pekny... teda reference na ukazatel ... tuhle konstrukci jsem snad v zivote nevidel :blink: fuj osklive, zlata java

edit: uz se v tom motam

on pořád myslí ty jeho crashe... kdy ukazatel ukazuje na neco, co uz je smazanyho.

ktere by timhle nejspis vyresit sly - ale vyzadovalo by to zmeny na dost mistech v core, a do toho se mu nechce

SneakerXZ · November 27, 2011

Pokud potřebuješ mít více kontroly nad těmi pointery potom se můžeš poohlídnout po smart pointerech. http://en.wikipedia.org/wiki/Smart_pointer

OneB1t · November 27, 2011

no dobry ale to znamena prepsat to uplne na vsech mistech ne? = silena prace

Nic neni jednoduchý a život neni fér.

SneakerXZ · November 28, 2011

Proto je lepší takovýhle věci používat hned při psaní a ne je dělat dodatečně. Bohužel pokud to chceš vyřešit nic jiného ti nezbude.

smarna to musi jit nejak inteligentne vyresit navic nikomu jinymu nez me se to nedeje nemuze to zpusobovat jeste neco jinyho (nastaveni kompilatoru, starsi ACE, etc..)?

Já pořád nevím, co pořádně máš za problém. Každopádně pokud máš dangling pointery, tak jiné řešení neexistuje a když si myslíš, že existuje nějaké inteligentní řešení, vymysli ho tedy a použij.

Wolf Officious · November 29, 2011

Sice se tu řeší mrtvý pahýly kopií ukazatelů, ale přidám taky trochu do mlýna, ikdyž to vezmu oklikou a úplně jiným směrem.

Mě se stávalo naprosto běžně (na TC2 s pravidelností západu slunce), že to padalo na různě blbě zvrstvených podmínkách. Budu to demonstrovat na obsahu metod příkazů:

if(GetSession()->GetPlayer())
{ ... }

Fungovalo to, ale když session neexistovala (třeba konzole žádnou session nemá), tak to padlo jednoduše proto, protože na základě NULL session to nemůže nikdy získat pointer hráče, žejo. Mohlo by, ale způsob ošetření třídy neznám. Možná to chce počítat v každém případě s NULL daty takovým způsobem (a všude), aby si s tím aplikace poradila. Co třeba throw / try / catch? http://www.builder.cz/art/cpp/cpp_vyjimky.html Nemám šajna, jestli se v myšlenkách ubírám správným směrem.

Ale zpět k příkladu v metodách příkazů. Řešením bylo boďto zakázat příkaz z konzole(nesouvisí s tématem), nebo místo kódu výše použít následující:

if(GetSession())
{
   if(GetSession()->GetPlayer())
   {
       // code...
   }
}

Není to sice dokonalý, ale pro daný účel dostačující. Třeba je kámen úrazu v něčem podobným. Neošetřená vyjímka, atp... Těžko ale soudit, OneB1tovu chybu jsem do podrobna nestudoval.

EDIT: ad SneakerXZ - Smart pointery: myslím že se v core na některých místech používají. Ruku do ohně za OC nedám, za MaNGOS možná jen prstíček.

add Smart pointers...

Bud ArcEmu, nebo Aspire Hearthstone par let zpatky na ne s velkou slavou presli...

o par tydnu/mesicu pozdeji potichu revertovali zpet, protoze emul bezel na smart pointerech vyrazne pomaleji - aspon co jsem tenkrat pochytil.

ale treba to tenkrat jen blbe pouzili

add vyjimky...

musel bys handlovat signaly od OS... u nekterych to lze, u nekterych ne

http://www.cplusplus.com/reference/clibrary/csignal/signal/

kuprikladu se tim necha obejit kill na linuxu kill -n 9 už ovšem ne.

if(GetSession())
{
   if(GetSession()->GetPlayer())
   {
       // code...
   }
}

Proč to psát takhle? Daleko lepší je to napsat následovně.

if (GetSession() && GetSession()->GetPlayer())
{
   // code...
}

Jinak smart pointery nějakou režii samozřejmě přidají, ale myslím si, že je zanedbatelná.

no to ja taky poradne nevim proto sem se ariczka ptal na ten crash a ten udelal topic o pointerech

jinak zkousel sem vcera uplne cistou revizi TC2 nejnovejsi z githubu (https://github.com/TrinityCore/TrinityCore/commit/1f70fd2851c52d7bbfeb58af8180cf3ad39af290) do 400 online rock stable od 500 do 900 to proste pada kazdou hodinu..

ted treba nejcerstvejsi crash

http://www.oneb1t.cz/paste/index.php/view/61583010

(bez debug rezimu nema to v nem cenu kompilovat informaci o tom crashi mam hromadu z poslednich 2 tejdnu...)

kdyby jste to nekdo vyresil a poslal mi k tomu nejakej navod pro truhliky pripadne rovnou patch tak bych byl moc stastnej

To můžou ale klidně být i načatý RAMky, nebo kixlý CPU.. Jestli tam má AMD, tak ty jsou tím nechvalně pověstný. Mám s tím dost drsnou zkušenost. Jak s AMD, tak s RAMkama. Vadný bloky a máš vymalováno. To bude padat pořát.

V první řadě bych udělal diagnostiku RAM a prověřil tak jejich spolehlivost. U mýho serveru (DELL) mám na to v BIOSu přímo utilitu, která to prověřuje. Ale jde to udělat třeba i při instalaci ubuntu (nebo i jinýho linuxu).. Myslím že ten nástroj je dostupnej i normálně v tom linuxu, jenom si nepamatuju, jak se jmenuje.
