To extend the tool for debugging more complex multi-threaded programs that utilize synchronization mechanisms like locks and semaphores, several enhancements could be made. First, the tool could incorporate visual representations of synchronization constructs, such as lock acquisition and release sequences. This would allow students to see when threads are waiting for locks and how this affects their execution flow.
Additionally, the tool could include detailed trace logs that highlight the interactions between threads and synchronization mechanisms. For example, when a thread attempts to acquire a lock, the trace could indicate whether the lock is available or if the thread is blocked, providing insights into potential deadlocks or contention issues.
Implementing step-through debugging capabilities would also be beneficial, allowing students to execute their programs one step at a time while observing the state of locks and semaphores. This would help them understand the timing and order of operations that lead to synchronization problems.
Moreover, the tool could feature case studies or real-world scenarios that demonstrate common pitfalls in multi-threaded programming, such as deadlocks or priority inversion. By analyzing these scenarios, students could learn to identify and resolve synchronization issues effectively.
