winpdb crashes with Python 3.12 at Windows

[macmacy]

Hi,
I've installed winpdb-reborn with pip. On attempt to start, winpdb crashes every time.
My environment:

• Windows 10
• Python 3.12.1

Crash info from Windows Event Log:

Hello

while I'm not affiliated in any way with the project, I can provide you with some information. First this project is very much abandonware, no contribution since 3 years+. Second, the underlaying debugger, rpdb2, contains the instruction 'import imp', this module is not available anymore since python 3.12. So you have no hope of debugging anything with winpdb under python 3.12, even if you managed to start it. Sorry for bringing you the bad news.

OK, thanks for info. In the meantime I've noticed the lack of imp in Python 3.12 - this is probably the root cause.

I had made the following modification on rpdb2.py few years ago, it works.

1. change "import imp" to "import importlib"
2. replace line "imp.load_source('__main__', _path)" in StartServer() with
    if sys.version_info[0] == 3: 
        if sys.version_info[1] >= 5:
            import importlib.util
            spec = importlib.util.spec_from_file_location('__main__', _path)
            module = importlib.util.module_from_spec(spec)
            spec.loader.exec_module(module)
        elif sys.version_info[1] < 5:
            import importlib.machinery
            loader = importlib.machinery.SourceFileLoader('__main__', _path)
            loader.load_module()
   elif sys.version_info[0] == 2:
        import imp
        imp.load_source('__main__', _path)
