Breakpoint and Step Over with multithreading

[pub-pub]

there's an issue with debugging python code that utilizes multithreading.
i set a breakpoint, start debugging, execution pauses as expected, but when i press 'Step Over' (F10) debugger does not go to the next expression (line) in the current thread, but jumps to some random locations in other running threads, and i have to 'Step Over' again and again until i return to my current thread.

'Step Over' feature must be limited the current (paused) thread.

the same issue was reported for Visual Studio a couple of years ago https://developercommunity.visualstudio.com/t/make-the-debugger-stick-to-the-current-thread-inst/351390

@pub-pub in debugpy the library there is a setting for this. Try adding this to the launch config: "steppingResumesAllThreads": false

thanks a lot, @karthiknadig
it's working great

but i had to hardcode False into pydevd_process_net_command_json.py because i don't know where exactly i should put "steppingResumesAllThreads": false in launch.json. can you, please, explain it to me?

and one more thing: maybe there's also a parameter that keeps me Stepping Over inside my thread without pausing all other threads?

@pub-pub debugpy has lot more control over this, but I am not sure if there is a stop only current option yet. This might be a feature request on debugpy. You can ask for it here https://github.com/microsoft/debugpy

       {
            "name": "Python Debugger: Current File",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "steppingResumesAllThreads": false
        }

Even though it has the yellow line it should work.
