进程结束，退出码为-1073741819 (0xC0000005) (Cython, TeamSpeak3)

Question

我现在的目标是创建team speak 3 manager服务(通过通道和其他通道切换用户):所以我创建了TS3 SDK库的包装器(用Cython for Python包装):https://mega.nz/#!pQdFjIwD!1vg8DPsFtYR4icVqWXzvpdbAQ47-n-aPz2niRkTU4fY(主模块:http://pastebin.com/PywhH4bf)在这个包装器中，我在模块中使用测试连接。要测试这个模块，只需导入这个。

我在python控制台(调用ts3client_startConnection后)得到消息:Process finished with exit code -1073741819 (0xC0000005)(访问冲突)

我还看到TS3回调是从非主线程调用的。

与此日志:

我也得到了不可重复的随机错误:

和

Fatal Python error: PyThreadState_Get: no current thread

Answer 1

由于缺乏可验证的示例，这是一点猜测。

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函数时还没有正确获取GIL。

添加with gil，如

cdef void onConnectStatusChang‌​eEvent(uint64 serverConnectionHand‌​lerID,
                                     int newStatus, 
                                     unsigned int errorNumber) with gil:

也许会有帮助。

在__main__()的末尾也没有代码，主线程至少是空闲的可能会更好。

if (error != ERROR_ok):
    print("Error connecting to server: %dn"% error)
print("Client lib initialized and runningn")

可以在print调用之后添加以下行以进行快速测试

import time
while True:
    time.sleep(1.0)
