我在我的应用程序中做了一些重复的操作(测试它),突然我得到一个奇怪的错误:
OperationalError: database is locked
我已重新启动服务器,但错误仍然存在。这到底是怎么回事?
最佳答案
来自 django 文档:
SQLite is meant to be a lightweight database, and thus can't support a high level of concurrency. OperationalError: database is locked errors indicate that your application is experiencing more concurrency than sqlite can handle in default configuration. This error means that one thread or process has an exclusive lock on the database connection and another thread timed out waiting for the lock the be released.
Python's SQLite wrapper has a default timeout value that determines how long the second thread is allowed to wait on the lock before it times out and raises the OperationalError: database is locked error.
If you're getting this error, you can solve it by:
- Switching to another database backend. At a certain point SQLite becomes too "lite" for real-world applications, and these sorts of concurrency errors indicate you've reached that point.
- Rewriting your code to reduce concurrency and ensure that database transactions are short-lived.
- Increase the default timeout value by setting the timeout database option
