Le problème surviens lors de la création du BSP-TREE dans le main, j'ai un crash à la dernière ligne :

int main (int argv, char* argc[]) {

Merci d'avance pour votre aide.

[Invité]

Mmmm, à priori il semble qu'il m'appelle le constructeur de copie en boucle, lors de l'appel à std::make_unique je vais essayé d'appeler un autre constructeur que le constructeur de copie.

[ternel]

Vu que tu trouves quasiment toujours quel est ton problème avant qu'on te réponde, tu ne pourrais pas essayer de réfléchir un peu plus longtemps avant de demander?

Non qu'on ne veuille t'aider, mais c'est assez dommage de voir des sujets lancé par quelqu'un, répondu par lui-même, sans autre intervention.

Ok je comprends mais là je ne vois pas du tout comment régler le problème.

J'ai essayé de cloner le std::unique_ptr mais sans succès :

Action::Action(const Action& other) {
    leaf = other.leaf;
    pressed = other.pressed;
    startEvent = other.startEvent;
    is_not = other.is_not;
    comparator = other.comparator;
    pressed = other.pressed;
    type = other.type;
    leftChild = other.leftChild.get()->clone();
    rightChild = other.rightChild.get()->clone();
}
std::unique_ptr<Action> Action::clone() {
    if (type == KEY_PRESSED_ONCE || type == KEY_HELD_DOWN || type == KEY_RELEASED)
        return std::make_unique<Action>(type, startEvent.key.code);
    if (type == MOUSE_BUTTON_PRESSED_ONCE || type == MOUSE_BUTTON_HELD_DOWN || type == MOUSE_BUTTON_RELEASED)
        return std::make_unique<Action>(type, startEvent.mouseButton.button);
    if (type == COMBINED_WITH_AND || type == COMBINED_WITH_XOR || type == COMBINED_WITH_OR)
        return std::make_unique<Action>(type, *leftChild, *rightChild);
    return std::make_unique<Action>(type);
}

J'ai toujours ce même crash.
Quand je commente les lignes ou je clone le std::unique_ptr ça ne crash plus par contre les feuilles de mon BSP-TREE ne sont pas clonée évidement. (leftChild et rightChild sont nullptr)

Est qu'il y a vraiment moyen de faire ça avec un std::unique_ptr, ne devrais je pas utiliser un std::shared_ptr plutôt ?

Merci.

[Invité]

Mmm il me semble que le shared_ptr est indispensable ici car je dois copier l'adresse du pointeur. (et non pas le contenu du pointeur)

Donc j'ai remplacé le std::unique_ptr par un std::shared_ptr, mais, si quelqu'un à une meilleure solution je suis preneur.

Non mais le pire c'est qu'il le fait à chaque thread, non seulement aux je-sais-pas-combien de threads qu'il a lancés, mais sur ceux des autres même quand y'a pas de rapport
Et bien sûr il ignore les réponses.
Perso j'ai arrêté de réfléchir à une solution, suffit de faire F5 et y'en a une qui pop (pas forcément la meilleure d'ailleurs, mais les autres étant automatiquement ignorées ...)

[ternel]

On dirait une série.
Après Batman, Superman, voici lolilolight, le développeur!

Au dernier épisode, il cherchait à cloner un unique_ptr...
Parviendra-t-il à déterminer qui possède la donnée pointée?
Saura-t-il voir que la donnée est interne ou externe?
Comprendra-t-il qu'une donnée interne n'est jamais donnée, mais copiée en sortie?
Qu'une donnée externe ne dois pas être possédée?

[Invité]

Ha voila. (le problème était ici)

Action Action::operator| (Action other) {
    Action result (COMBINED_WITH_XOR, *this, other);
    return result;
}
Action Action::operator|| (Action other) {
    Action result (COMBINED_WITH_XOR, *this, other);
    return result;
}
Action Action::operator&& (Action other) {
    Action result (COMBINED_WITH_XOR, *this, other);
    return result;

Je ne peux pas créer un unique_ptr sur une donnée temporaire, sinon elle sera détruite avec le std::unique_ptr.
Donc je la copie et ensuite je fais le std::unique_ptr.

Bon maintenant j'ai un autre problème avec le thread, mais je vais chercher un peu cette fois avant de poster.

[ternel]

Normalement, le constructeur de unique_ptr doit recevoir directement un new.

unique_ptr supprime l'écriture des delete par le code métier.
De la même manière, make_unique supprime l'écriture de new, en le faisant lui-même.

Il n'en reste pas moins que donner l'adresse d'une variable sera nécessairement une faute.
