Memory leaks can cause Go program memory to continuously increase by: closing resources that are no longer in use, such as files, network connections, and database connections. Use weak references to prevent memory leaks and target objects for garbage collection when they are no longer strongly referenced. Using go coroutine, the coroutine stack memory will be automatically released when exiting to avoid memory leaks.

How to use Golang's error wrapper? How to use Golang's error wrapper? Jun 03, 2024 pm 04:08 PM

In Golang, error wrappers allow you to create new errors by appending contextual information to the original error. This can be used to unify the types of errors thrown by different libraries or components, simplifying debugging and error handling. The steps are as follows: Use the errors.Wrap function to wrap the original errors into new errors. The new error contains contextual information from the original error. Use fmt.Printf to output wrapped errors, providing more context and actionability. When handling different types of errors, use the errors.Wrap function to unify the error types.
