Question

我有一个二进制文件，99％的时间运行良好。并且不时地，我无法理解，它与此输出崩溃。在重新启动之后，一切正常。

二进制文件是一个模板系统。它用占位符来读取一些模板 {％foo％}或{％include：foo％}分别为：

在当前上下文中查找“foo”（std :: map）
在那里包含一个名为“foo”的子模板（与给定的存储过程一样多次返回行）覆盖/添加到当前的std :: map上下文。

每个模板生成器获取其自己的上下文副本，然后在其自己的线程中执行，在该线程中将生成的输出保存到文件并将其发送到MQ。一旦每个生成器返回，所有内容都被清理，exe返回0。

我甚至不使用双向链表（或任何地方的任何表格或链表）。我不理解这种崩溃，即使它们似乎与某些多线程堆损坏有关。

我欢迎任何提示：

我怎样才能更频繁地重现这个，以便我可以调试它？

我应该在哪里寻找什么？

基本上我的ibm和我的sybase TDS驱动程序的mq lib正在做废话吗？我检查了“我的调用”几乎所有内容都是在一个函数或另一个函数内部的堆栈上构建的。

Answer 1

我会说

Syscall param semctl(arg) points to uninitialised byte(s)

匹配此部分：

I checked "my calls" nearly everything is build _on the stack locally inside one function or another_.

^如果一个线程超出了创建它的范围，那么会导致问题。具体来说，如果你在堆栈上创建一个信号量，它会导致像valgrind报告的错误

#include <semaphore.h>
#include <time.h>
#include <assert.h>
#include <errno.h>
#include <signal.h>

void foo()
{
    sem_t sem;
    pthread_t th;
    pthread_attr_t attr;
    int s = pthread_attr_init(&attr);
    // error handling
    s = pthread_create(&th, &attr, &thread_start, static_cast<void*>(&attr));

} // oops

我知道这可能不是你的代码的样子，只是草绘图片：）

因为我能做的很少。看起来这个驱动程序/插件不是很强大。

Answer 2

如果您从多个线程访问数据库驱动程序，那么驱动程序中可能存在问题，并且有两种解决方案：

通过互斥锁保护对驱动程序的所有访问。理想情况下，为数据库访问创建一个包装类来强制执行此操作。
创建驱动程序的多个实例，每个线程一个。

只能在创建连接的线程中使用连接。不支持在线程之间移动连接或从其他线程创建查询。

这意味着您不能在一个线程中使用cloneDatabase，并在另一个线程中使用克隆连接。您必须通过在您希望使用该连接的线程中运行的代码创建然后打开一个全新的独立连接。

您必须非常小心，无论您传递给线程的隐式共享类实际上是单独的实例。 如果它们是引用，const引用或指针，则是。有关详细信息，请参阅this answer。
