Breakpoints with multiple files

Bug report

Consider the following structure:
a.py (foo())
'- b.py (bar())
meaning that a.py with foo() calls some function from b.py, namely bar().

Now, add a breakpoint to b.py and let the debugging begin. You will see that the debugger seems to simply overlook the breakpoint in b.py. In other words: Breakpoints are only accepted, if the next line to be executed before clicking on "Go" is in the same file.

This is rather bothersome and does work correctly in other IDEs like Qt for C++.

The solution

Please "step down" to a breakpoint by design.

Your environment

• CPython versions tested on: 3.11.1
• Operating system and architecture: Windows 10

在 Windows 10 上使用 CPython 3.11.1，通过 a.py 调用 b.py 中的 bar() 来复现该报告，然后跟踪调试器的断点和单步执行入口点。确认当执行从 a.py 开始时能够命中 b.py 中的断点，并为预期的跨文件行为添加回归覆盖。
