Python “为什么我的功能”；挂起；

大家好，我现在正在使用MySQLdb。出于某种原因，在运行了大约30分钟后，我的应用程序完全停止了。看来这个函数正在阻止我。（不知道是什么原因）

顺便说一句，这是表格：

  File "/usr/lib/python2.6/multiprocessing/process.py", line 231, in _bootstrap

    singleCur.execute( """SELECT templateBuilt FROM templateEnough WHERE netloc=%s""", [ netlocH])
  File "/var/lib/python-support/python2.6/MySQLdb/cursors.py", line 153, in execute
    r = self._query(query)
KeyboardInterrupt

有什么想法吗

根据您的回溯，您在执行

checkTemplateBuild

时中断了脚本，而不是

enoughPassedForTemplate

---

我认为问题在于代码的另一部分；也许某处有一个无限循环？可能在

运行

功能中？

表上可能有一个锁阻止查询完成。

在执行查询字符串之前，请尝试将其记录到文件中。

然后，当您认为它已挂起时，可以查看查询并查看它是否可以手动运行

我重新编辑了我的粘贴。我不认为我会有一个无限循环，真的吗？如何确定？对于innodb，可以使用“显示enginge innodb状态”，请参阅。不确定内存引擎。您的意思是在游标执行SQL语句之前打印SQL语句？好的。如果您知道程序挂起的是哪个查询，那么您可以在mysqlclient中运行相同的查询，看看那里发生了什么。您可以尝试查询的变体。这看起来是一个足够简单的查询，所以挂起的原因可能很奇怪。分而治之
