An example of an AI chatbot conversation about common mistakes with locks and semaphores in programming.
What are some common mistakes when using locks and semaphores?
Some common mistakes include deadlocks, forgetting to release locks, and using the wrong type of synchronization.
Can you explain what a deadlock is?
A deadlock occurs when two or more threads are waiting for each other to release resources, causing them to be stuck.
How can I avoid deadlocks in my code?
To avoid deadlocks, you can use a timeout for acquiring locks, or implement a lock hierarchy to ensure a consistent order.
What is the difference between a lock and a semaphore?
A lock allows only one thread to access a resource at a time, while a semaphore can allow multiple threads based on its count.
