What are goroutine leaks and how can I prevent them?

What are goroutine leaks and how can I prevent them?

Goroutine leaks occur when goroutines are not properly terminated, leading to resource wastage. To prevent them, ensure you manage goroutine lifecycles carefully, using channels or context to signal completion.

Can you give me an example of a goroutine leak?

Sure! A common example is starting a goroutine that waits for a channel to receive a value, but if the channel never receives, the goroutine remains active indefinitely.

How can I detect goroutine leaks in my application?

You can use tools like Go's built-in pprof package to analyze goroutine usage and identify leaks by checking for goroutines that are still running after they should have completed.

What are the best practices for managing goroutines?

Best practices include using context for cancellation, limiting the number of concurrent goroutines, and ensuring proper error handling to avoid leaks.
