MySQL文件系统先睹为快(3)_MySQL
六、写权限？
在开发的第二阶段，会有措施执行SQL 语句。现在的思路是：
采用目录：
/mountpoint/database/.command/
然后执行命令，把SQL 语句作为目录建立。
或者建立目录把SQL 语句作为文件放入这个目录。
两个方案都有优点，第一个方案可以重新使用SQL 语句，但是这样的目录名实在不敢令人苟同。第二个方案采用信号量文件，语句执行完毕就删除这个文件，没有任务使用时，目录也被删除。对于那些慢速的查询响应，可以选择timeout 的时间。
七、权限管理
在权限管理方面，可以使用Unix 的权限管理方式，这样的方案看来是最好的。

Which AI programmer is the best? Explore the potential of Devin, Tongyi Lingma and SWE-agent
Apr 07, 2024 am 09:10 AM
On March 3, 2022, less than a month after the birth of the world's first AI programmer Devin, the NLP team of Princeton University developed an open source AI programmer SWE-agent. It leverages the GPT-4 model to automatically resolve issues in GitHub repositories. SWE-agent's performance on the SWE-bench test set is similar to Devin, taking an average of 93 seconds and solving 12.29% of the problems. By interacting with a dedicated terminal, SWE-agent can open and search file contents, use automatic syntax checking, edit specific lines, and write and execute tests. (Note: The above content is a slight adjustment of the original content, but the key information in the original text is retained and does not exceed the specified word limit.) SWE-A
