查找正在运行的python进程的当前行号 [英] Find the current line number of a running python process

问题描述

我有长时间运行的python程序，没有足够的内部日志记录.我希望能够附加到正在运行的python程序，并找出它的当前行号.理想情况下，我希望在不中断其执行的情况下执行此操作，但是我很高兴让它暂停，打印堆栈t种族，然后继续前进.

我可以轻松键入control-C，但这会终止程序.

有什么办法吗?

解决方案

好像 py-spy py-spy 是您要寻找的.

它可以连接到正在运行的进程，而无需修改并显示其当前操作.

I have long-running python programs that do not have sufficient internal logging. I'd like to be able to attach to a running python program and find out it's current line number. Ideally, I'd like to do this without interrupting its execution, but I'm happy to have it pause, print the stack t race, and then keep going.

I could easily type control-C, but that would kill the program.

Is there any way to do this?

解决方案

Seems like py-spy is what you are looking for.

It can connect to running process without modifying and show what it currently do.
