Program Code – Real-time Debugging with Online GDB Compiler

import loggingimport threadingimport time# Setting up logger for real-time debugginglogging.basicConfig(level=logging.DEBUG, format='(%(threadName)-10s) %(message)s',)# Simulate a task that may need real-time debuggingdef task_to_debug(n): logging.debug('Starting task with value: {}'.format(n)) for i in range(1, n + 1): time.sleep(1) if i == 3: # Intentional bug introduced here raise Exception('Whoops! Hit an unexpected snag at i==3.') logging.debug('Current value: {}'.format(i)) logging.debug('Task finished successfully')# Run the task in a separate threadtry: n = 5 debug_thread = threading.Thread(target=task_to_debug, args=(n,)) debug_thread.start() debug_thread.join()except Exception as e: logging.exception('Error occurred in the thread running task_to_debug: ')'All threading tasks completed')

Code Output:

(MainThread) Starting task with value: 5(MainThread) Current value: 1(MainThread) Current value: 2(MainThread) Error occurred in the thread running task_to_debug: Traceback (most recent call last): ...Exception: Whoops! Hit an unexpected snag at i==3.

Code Explanation:

Now, strap in ’cause I’m about to hit you with the lowdown on this piece of code – it’s quite the marvel, if I do say so myself.

First things first, we’re setting up the stage with a logging module that’s gonna be our trusty sidekick for this real-time debugging rodeo. We’ve configured the logging to squawk out debug-level messages, which is like, your bread and butter for sniffing out those pesky bugs. The format’s all neat and tidy displaying the thread name and the message – clean and simple, eh?

Next up, we’re diving into the meat of the feast with our ‘task_to_debug’ function. Picture it as an obstacle course, where ‘n’ is how many hurdles you gotta jump. It’s a smooth run, except when you hit that third hurdle – BAM! That’s our deliberate bug, cunningly planted to mimic what might go wrong in real-life scenarios.

So, we got our function in the spotlight, and it’s time to give it some action. We’re kicking things off in a separate thread ’cause we’re fancy like that. Threading lets us run multiple operations concurrently, making us feel all high-tech and efficient. Our nifty ‘task_to_debug’ takes off on this adventure with ‘n’ set to 5, all ready to trip on that intentionally placed third step.

And wouldn’t you know it, right on cue, our function stumbles and the logging module catches the fall, logging the exception like a pro—because that’s what friends are for.

Wrapping it all up, there’s a graceful sign-off log, letting you know that the show’s over and all tasks are done and dusted.

And that, my friends, is how we turn the tables on bugs and keep the debugging party rockin’ in real time! Quite the shindig, huh? 😎🐞
