进程已完成，退出代码为 -1073741819 (0xC0000005)（Cython、TeamSpeak3）

Question

我现在的目标是创建 team speak 3 经理服务（通过频道切换用户）：所以我创建了 TS3 SDK lib 的包装器（用 Cython 包装 Python）：https://mega.nz/#!pQdFjIwD!1vg8DPsFtYR4icVqWXzvpdbAQ47-n-aPz2niRkTU4fY (main module: http://pastebin.com/PywhH4bf）在这个包装器中，我在模块中使用了测试连接。要测试这个模块，只需导入这个。

我在 python 控制台中收到消息（在调用 ts3client_startConnection 之后）：Process finished with exit code -1073741819 (0xC0000005)（访问冲突）

而且我看到 TS3 回调是从非主线程调用的。

有了这个日志：

我也遇到了不可重复的随机错误：

和

Fatal Python error: PyThreadState_Get: no current thread

Answer 1

由于没有可验证的例子，所以有点猜测。

如果从 C 库 (ts3client_*) 创建的线程调用这些处理程序函数，则在调用 python 函数时尚未正确获取 GIL。

加with gil赞

cdef void onConnectStatusChang‌eEvent(uint64 serverConnectionHand‌lerID,
                                     int newStatus, 
                                     unsigned int errorNumber) with gil:

可能会有帮助。

__main__()末尾也没有代码，最好是主线程至少是空闲的

if (error != ERROR_ok):
    print("Error connecting to server: %d\n"% error)

print("Client lib initialized and running\n")

可以在打印调用之后添加以下行以进行快速测试

import time
while True:
    time.sleep(1.0)
