여러 메모리 누수가있는 GTK가있는 GUI

Question

잠시 동안 GTK-3.0을 배우기 시작했고 필자가 일하는 프로그램을위한 GUI를 만들기 시작했습니다.

프로그램은 아무런 경고없이 잘 컴파일되지만, valgrind을 실행하면 메모리 누수가 많이 발생하며 내가하는 일을 파악할 수 없습니다.

필자는 프로그램을 문제를 쉽게 설명 할 수있는 최소한의 코드로 축소했습니다. 코드를 다음과

잘 컴파일하지만, 메모리 누수의 많은 :

#include <gtk/gtk.h> 

int main(int argc, char *argv[]){ 
    gtk_init(&argc, &argv); 
    GtkWidget *window; 
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL); 

    g_signal_connect(window, "delete-event", G_CALLBACK(gtk_main_quit), NULL); 
    gtk_widget_show(window); 
    gtk_main(); 
} 

나는 그것을 컴파일 :

valgrind --leak-check=full --track-origins=yes --leak-check=full ./app 

:

gcc -Wpedantic -std=c11 -Wall -Wextra -Werror -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -Wconversion -Wshadow -Winit-self -Wfloat-equal -Wwrite-strings -O0 -g main.c -o app `pkg-config --cflags gtk+-3.0 ` `pkg-config --libs gtk+-3.0 ` 

와 나는 다음과 같은 명령으로 valgrind를 실행 한 후

출력이 다음과 같습니다.

책을 읽고 GTK3 Manual을 읽고 난 다음에 누수가 어디 있는지 알아낼 수 있습니다.

여기 GUI가 잘못 되었습니까? 매뉴얼에서 나는 올바른 방법으로 코드를 작성했음을 거의 확신한다.

valgrind 출력에 calloc과 realloc이 호출 된 것을 보면 이는 역시 free() 호출이어야 함을 의미합니다. GTK +로 메모리를 해제하려면 어떻게해야합니까?

Answer 1

여기에 여러 번 대답 해 왔습니다. 이 응용 프로그램의 수명에 필요한 내부 버퍼를 할당하고 할당 해제에 관해서

GTK + 꽤 게으른이 내가 중간에 사용되는 포럼에이 질문 다른 사람에 대한 답변으로 준 것입니다 . 예를 들어, 응용 프로그램의 수명에 필요한 초기화 동안 룩업 테이블을위한 메모리 영역을 할당 할 수 있습니다. GTK +는 결코 이것을 할당 해제하지 않습니다. Valgrind는 메모리 누수처럼 보입니다 (기술적으로는 그렇습니다). 그러나 최적화로 인해 GTK +는 응용 프로그램을 종료하는 동안 할당이 취소되고 오류가 발생하지 않으므로 할당을 해제하지 않습니다. Valgrind가 이것을 무시할 수 있도록 억제 파일이 필요한 이유입니다. 문제는 대부분의 GTK + 버전 변경으로이를 변경해야한다는 것입니다.

보고있는 것은 오 탐지입니다. valgrind가 무시할 수 있도록 억제 파일을 사용할 수 있습니다. 당신은 자신의 것을 만들거나 이미 완료된 것을 검색 할 수 있습니다.
