Debugging is important, since everyone will make mistakes. Python has perfect traceback to help you find the problem. However, for asynchronous program, debugging has been divided into two levels – the application level and the eventloop level.
Here’s a simple example of debugging:
import futurefinity.web import asyncio loop = asyncio.get_event_loop() loop.set_debug(True) app = futurefinity.web.Application(debug=True, loop=loop) @app.add_handler("/") class MainHandler(futurefinity.web.RequestHandler): async def get(self, *args, **kwargs): raise HTTPError(500) return "Hello, World!" app.listen(23333) try: loop.run_forever() except KeyboardInterrupt: pass
For most cases, the bug comes from the application, you can just turn on the application level
debugging by passing
debug=True to Application Class as a keyword argument.
For some rare situations, which means the FutureFinity itself may have bugs,
we can use eventloop level debugging by executing
before the eventloop starts.
You’ve finished this simple tutorial; however, this is not an end, this is a new start. You can see the rest of the documentation to comprehend FutureFinity deeper, or just write a simple application.
